  • Assessment of the dynamic stability of mine-rollers-equipped heavy vehicle   Order a copy of this article
    by Mostafa I. Yacoub, Mootaz E. Abo-Elnor, Ahmed M. Ali, Ibrahim A. Elsherif, Mohamed A. El-Latif, Alhossein Mostafa Sharaf 
    Abstract: One of the strategies to protect vehicle platoons against Improvised Explosive Devices (IEDs) is to use a mine-roller mounted at the front of the vehicle with a telescopic lever and fork ending with two sets of freely rotating solid tyres. However, rough vehicle handling or cornering in unstable conditions may be encountered particularly at high speeds. This paper presents a detailed investigation to ensure sufficient handling and stability of mine-rollers-equipped vehicle. In the design phase, both the kinematic and dynamic analyses are illustrated. The mathematical analysis of the dynamic stability problem is validated by in-field measurements of a real mine-rollers-equipped heavy vehicle. Results show that vehicle stability could be achieved using the pre-manufacturing mathematical analysis illustrated in this article. Furthermore, the analysis is extended to address the effect of some mine-rollers design parameters, such as increasing setup length and weight, which would certainly enhance the protection of the mobile platoon.
    Keywords: mine-rollers; heavy vehicle stability; handling performance; convoying security.

    Abstract: As an emerging technology, deep learning has been well-used in many fields. This paper mainly studies the application of deep learning in smart cities about port cargo throughput forecasting. Firstly, the port cargo throughput is analysed by Principal Component Analysis (PCA). Correlation analysis was carried out on the impact factors, and the screened GDP and container throughput was put into the multivariate long-term short-term memory neural network (LSTM) as external input factors to improve the accuracy, and a multivariate LSTM prediction model based on PCA was built; then, using the errors generated by the prediction model in the prediction of cargo throughput in Ningbo Zhoushan Port as training data, training to generate error sequences, and the prediction data are subjected to error correction to increase the prediction accuracy. Lastly, the model's forecast outcomes are contrasted with the vector autoregressive model (VAR), Holt-Winters, grey prediction model, and univariate LSTM model prediction results were compared and analysed. The comparison results show that the multivariate LSTM prediction model based on PCA and error correction has higher prediction accuracy

    by Song Zhongchao, Zhang Liwei, Zhang Menglei, Jiao Yanbin 
    Abstract: To improve the trajectory tracking ability of multi-module articulated vehicles, an all-axle active steering control strategy based on feedforward-feedback control is proposed. Based on the kinematics model, the expected steering angle is calculated as the feedforward control signal. The trajectory error of each axle is defined, a vehicle controller based on sliding mode control algorithm is designed to obtain additional steering angle as the feedback control signal.

  • Vibration optimisation of truck cargo transport compartment using numerical simulation   Order a copy of this article
    by Mostafa Mirtabaee, Seyed Amirhossin Ahmadi 
    Abstract: Reducing vibrations in truck cargo transport compartments has become increasingly important to prevent damage to the cargo and ensure the safety of passengers. Optimising truck cargo transport compartments based on transportation vibration standards, such as MIL-STD-810H, can considerably improve their performance, reduce transportation damages, and increase the agility and speed of heavy vehicles. The purpose of the current research is to analyse and optimise the cargo transport compartment of the Benz 911 truck by numerical methods. For this purpose, the frequency transfer function of the truck cargo transport compartment is determined by considering the effects of the weight of loads and road and engine dynamic forces at natural frequencies. Finally, after 14 optimisation steps, the obtained weight reduction is 38.8% compared with the initial state, and the maximum acceleration has also been reduced by 56.6% compared with its initial value.

  • Study on cold chain logistics vehicle path optimisation method based on improved artificial bee colony algorithm   Order a copy of this article
    by Fengju Chen, Jingzhao Zhang 
    Abstract: Cold chain logistics describes the process of transporting and storing perishable items from their point of manufacture to the final customer transportation and storage facilities equipped with refrigeration systems. Using cold chain logistics, perishable foods such processed foods, meats, seafood, ice creams, poultry, dairy products, vegetables, and fruits can be safely transported from the producer to the consumer. Effective planning of the cold chain logistics vehicle is crucial for minimising travel time, distance, and overall logistics costs in order to get the product to the consumer. One such artificial swarm intelligence technique is the Artificial Bee Colony (ABC) algorithm , which is inspired by the activities of bees and their colonies.

  • Practice of fast body attitude control for multi-axle active suspension vehicles via bi-directional attitude-suspension kinematics modelling   Order a copy of this article
    by Fan Zhang, Zhenhua Wu, Chu Li, Jintian Cai, Jiguo Yang 
    Abstract: Multi-axle off-road vehicles with suspension lifting function can achieve some robotic manoeuvring effects through body attitude and wheel lifting adjustment, but carry larger loads. In the face of the hyperstatic and coupled-bearing challenges of multi-axle suspension systems, constructing a kinematic model to guide attitude transitions is a fundamental part of active suspension control. Firstly, the bi-directional kinematic relationship between body attitude and suspension displacement on uneven ground is presented to provide graphical interaction for the driver. Secondly, multibody dynamics simulations are carried out for vehicle state calculation and body attitude adjustment. Finally, a three-axle independent hydraulic suspension experimental platform is developed, and active attitude control experiments are carried out. Experimental results show that the scheme can achieve flexible and effective attitude control of multi-axle vehicles under complex ground conditions, thus playing a positive role in enriching the active suspension control functions of multi-axle vehicles and supporting the vehicle extrication.

  • Research on active suspension-based anti-rollover control strategy for side-unloading dump trucks during lifting operations   Order a copy of this article
    by Tianmin Zhu, Mingmao Hu, Qinghe Guo, Min Liu, Renjun Liu, Mengchao Wang, Zhongcheng Fu, Yu Wang 
    Abstract: Aiming at the problem of poor stability of side-unloading dump trucks under lifting conditions, an anti-rollover control strategy combining active suspension and fuzzy sliding mode control was proposed. Considering the changes in the mass and spatial position of the cargo during lateral unloading, a four-degree-of-freedom side-unloading dump truck nonlinear model was established, and the model's accuracy was validated using MATLAB/Simulink. The adjustment of sliding mode control parameters is realized through fuzzy logic, and the fuzzy-sliding mode controller is used to obtain the anti-roll moment that suppresses suspension deformation. A rollover warning controller was designed using the ratio of the right wheel load to the total vehicle weight as the rollover evaluation index. Simulation is conducted using ordinary sliding mode control and without any control for comparison. The results indicate that this strategy enhances the lateral stability of side-unloading dump trucks under lifting operations, effectively preventing rollover incidents.

  • Development of a direct yaw moment control strategy for an articulated bus equipped with on-board electric motors   Order a copy of this article
    by Kerem Bayar 
    Abstract: Considering the damping moment associated with the articulation joint of buses, the degree of actuation freedom increases, for stabilising the vehicle during harsh manoeuvres on slippery surfaces. With this background, this study aims at developing a direct yaw moment control strategy for an articulated bus, equipped with on board electric motors at middle and rear axles, that is capable of braking / accelerating the left and right wheels independently. The yaw moment control problem is treated as a control allocation problem, where the corrective yaw moment action for front and rear compartments, is distributed onto individual wheel braking/acceleration and articulation joint damping moment. Through lane change and snaking manoeuvre simulation results, the effectiveness of the proposed controller is shown, in terms of tracking the desired front and rear compartment yaw rates. This is achieved without sacrificing vehicle sideslip and articulation angles.
    Keywords: direct yaw moment control; articulated bus; control allocation; yaw rate; articulation angle; vehicle sideslip angle; on board electric motor.

  • Lightweight security scheme for data management in the e-commerce platform   Order a copy of this article
    by Zhiwen Cai, Jingying Ke 
    Abstract: This paper proposes Lightweight Distributed Accessible Control (LW-DAC) for data management to secure users' data in an E-commerce Platform. The Lightweight Security method enables distributed user information access control for protected users. This system's security is reduced to the Bilinear Discrete Diffie-Hellman (BDDH) assumption, which helps the Decision Making Algorithm minimize the execution time. The proposed method provides easy data encryption, trapdoor keyword generation and data recovery. BDDH filters the keyword search to avoid accessing the terminal. The algorithm has been compared with the existing system and proven based on reliability and scalability highly efficient. The simulation analysis demonstrated that the proposed Lightweight Security Scheme for data management system encrypts the user data and prevents the backdoor access with high scalability, performance, and lesser mean square error.

  • Optimisation-enabled deep learning model for traffic sign recognition   Order a copy of this article
    by Soja Salim, J.S. Jayasudha, B. Soniya 
    Abstract: A novel optimisation algorithm-trained deep learning network is developed to recognise all symbol-based traffic signs. The deep learning method employed here for the recognition is Deep Q Network (DQN) with an optimization algorithm, named Gradient Descent- Team Work Optimisation algorithm (GD-TOA), for training the DQN. Initially, the Gaussian filter is used for the pre-processing phase, in which the noise can be eliminated. Thereafter, the sign localisation is performed using SegU-Net with a modified loss function that includes balance cross-entropy, rescaled hinge loss, and insensitive loss to localise the sign region from the image. Finally, TSR is performed using the proposed GD-TOA-based DQN so as to improve the TSR performance. The experimentation reveals that the proposed GD-TOA-based DQN technique attains an overall improvement regarding the precision, accuracy, recall, and F measure with values 0.977, 0.972, 0.971, and 0.973, respectively.

  • Real-time emission test and evaluation method of heavy-duty diesel vehicle SCR system based on dynamic time warping   Order a copy of this article
    by Xuejian Ma, Tao Qiu, Yan Lei, Zexun Chen 
    Abstract: Selective catalytic reduction (SCR) technology is the most important technical to solve the high NOx emission of diesel vehicles. In-use heavy-duty diesel vehicles must undergo emission spot checks at inspection stations to avoid exceeding the NOx emission limits due to abnormal operation of the SCR system. A method that can quickly carry out in-situ emission tests on heavy-duty diesel vehicles on the road to evaluate SCR operation status is of great significance. In this paper, a method based on dynamic time warping (DTW) is proposed to quickly judge the SCR operation status when the vehicle is stationary. The variation of similarity between SCR inlet NOx and SCR outlet O2, the variation of similarity between SCR outlet O2 and SCR outlet NOx, and the effect of SCR working efficiency on SCR outlet O2 were analysed through experiments, and the proposed method was validated.

  • A review of road surface recognition and tyre-road friction coefficient estimation methods   Order a copy of this article
    by Linhui Wang, Xiaobin Fan, Xueliang Yu, Zipeng Huang, Kaikai Zhao 
    Abstract: The tyre-road friction coefficient (TRFC) characterises the maximum interaction force that can be generated between the road surface and the tire, which directly affects the driving, braking, and handling stability of vehicles. Obtaining accurate estimates of TRFC can optimise the vehicles active safety control and improve decision-making and planning performance in autonomous driving. However, the existing TRFC identification methods are not very accurate and real-time when dealing with sudden changes inroad conditions under extreme working conditions. Therefore, this paper discusses the current domestic and international road recognition methods, provides a review based on recognition principles, and elaborates on the two main categories of existing identification methods. It introduces the adhesion rate estimation and road type recognition methods commonly involved in TRFC identification, analyses the new methods brought by neural networks and rubber friction theory to the adhesion coefficient estimation issue, and provides an outlook on future development directions.

  • Community transport experiences, in connection with diesel-LPG mixed operation buses belonging to the category of heavy vehicles   Order a copy of this article
    by István Lakatos 
    Abstract: Various international literature sources and papers address the issue of the theoretical implementation of using liquefied petroleum gas (LPG) gas as catalyst material injected into the carburetor system of diesel engines and its positive impact on the characteristic features of the engine and its emission. In Europe, for example, Landi-Renzo, one of the biggest Italian companies dealing with traditional gas systems, is developing a compressed natural gas (CNG)-diesel system. The present paper outlines the operational characteristics of a diesel LPG dual operating system based on our own experiments and measurements which have been carried out on the transformed buses of the Southern Transdanubian Transportation Centre (DDKK, Hungary). In the process of evaluation two aspects were taken into consideration: the impact on emission and that on fuel consumption. Of course, the tests can be extended to wider areas, which take into account both vehicle structures and the environment (Palkovics and El-Gindy, 1993; Palkovics et al., 1996; Shokouhfar et al., 2016).

  • Lateral stability control of heavy-towing taxi-out based on differential braking   Order a copy of this article
    by Jiahao Qin, Jiaqi Ma, Peiyang Xu, Wei Zhang 
    Abstract: The new mode of towing taxi-out consisting of rodless tractor and aircraft, is prone to extreme lateral instability accidents such as slipping and jack-knifing during high-speed turns. To address this issue, a ten-degree-of-freedom dynamic model of the aircraft towing system is established using the Lagrangian analysis method. This model does not consider constraints and limitations at hinge points. Based on this model, a high-speed turn differential braking controller uses yaw rate deviation as yaw moment controller inputs and determine their respective additional yaw moments. According to the braking strategy and braking moment allocation rules, the controller outputs the required braking moments for the target wheels. Finally, through Matlab/Simulink simulations, the steering angle input and initial speed are varied under J-turn and double lane change condition. This allows the delineation of safe and dangerous areas for steering angles and speeds in towing taxi-out mode, and a comparison of the control effectiveness of differential braking.

  • ANN-based RBF prediction for maximal energy recovery using hybrid optimisation in electric vehicles   Order a copy of this article
    by A. Velu, N. Chellammal 
    Abstract: Owing to the increasing number of Electric vehicles (EVs) that have propelled the global trend towards transportation electrification over the past few decades, the automotive industry has expanded its excessive investment in transportation electrification technology. However, the widespread maintenance of EVs is significantly complicated by their short driving range. Therefore, a lot of research is done to improve the efficiency and driving range of automobiles in both business and academia. The operational range of EVs can be expanded using regenerative braking technology. Initially, the parameters, like speed of the EV and State of Charge (SOC) of the battery are taken as input to the Artificial Neural Network (ANN) and the corresponding predicted regenerative braking force has been obtained as the desired outcome of ANN. The estimated accurateness of the ANN classifier is then enhanced by optimally altering its weight parameters by Wild Horse Insisted Sparrow Search Optimization (WHI-SSO).

    by Wei Gao, Wei Minxiang, Yuping He, Deng Zhaowen, Yonghui Jin, Baohua Wang 
    Abstract: This paper presents a coordinated control strategy for acceleration slip regulation (ASR) and direct yaw moment control (DYC) to improve the lateral stability of a distributed in-wheel motor drive electric articulated heavy vehicle (DIMDEAHV). A non-linear TruckSim model and a linear three-degree-of-freedom (3-DOF) yaw-plane model of DIMDEAHV are generated, and their fidelity is evaluated. An algorithm is then developed to identify road conditions using the - standard curve of the Burckhardt tire model. Built upon the road identification algorithm, an ASR controller is designed and proved to be effective in preventing wheel slip. Finally, a coordinated control strategy for ASR and DYC is developed and validated using co-simulation under a double lane change (DLC) manoeuvre. The simulation results demonstrate that compared to the DYC alone, the ASR and DYC coordinated control can effectively prevent the wheel slip and improve the lateral stability of the DIMDEAHV traveling at high speeds on

  • Research on ride comfort control of electro-hydraulic active suspension based on intelligent optimisation control strategy   Order a copy of this article
    by M.C. Wang, Renjun Liu, Qinghe Guo, Huihui Zhou, Shilu Guo, Weiliang Xu 
    Abstract: High-frequency excitation signals pose a severe impact on human health during vehicle operation. Designing a control strategy to enhance vehicle dynamic performance for the system of electro-hydraulic active suspension, characterised by parameter uncertainties and high-dimensional nonlinearity, is a significant challenge. In response, an intelligent optimisation control strategy was proposed: The Multi-Strategy Improved Beluga Whale Optimisation (MSIBWO) was used to optimise the parameters of a Hybrid Hierarchical Controller (HHC). The outer layer of the HHC employs impedance control to calculate the desired force. The inner layer uses a Fractional Order PID (FOPID) controller to control the nonlinear electro-hydraulic servo actuator, characterised by time-varying parameters, ensuring it tracks the desired force. Simulation analyses conducted in MATLAB/Simulink reveal that the proposed MSIBWO algorithm surpasses the BWO algorithm regarding convergence accuracy and speed. Furthermore, the intelligent optimisation control strategy significantly improves vehicle ride comfort while maintaining driving safety on high-frequency road surfaces.

  • Research on optimisation of regenerative braking strategy for pure electric mining dump truck based on MPC   Order a copy of this article
    by Weiwei Yang, Wenming Zhang, Nong Zhang 
    Abstract: With the development of environmental protection concepts, the proportion of battery electric mining trucks is gradually increasing. However, the problems of charging mileage and battery life degradation limit the application. Meanwhile, production efficiency is also reduced due to slower charging and battery replacement speeds. The paper mainly focuses on the problem of decreased battery life and the shorter driving range of a 50-ton pure electric mining dump truck, considering the influence of the shifting strategy. A model predictive control (MPC) algorithm is proposed, which verifies that the MPC strategy can reduce energy consumption and improve battery lifetime by comparing the original rule-based control algorithm. The simulation results show that the proposed MPC strategy can reduce energy consumption by 16.92% and reduce battery life loss by 18.21% in the typical cyclic working conditions of mining roads.

  • Lateral stability classification and active stabilisation of towing taxi-out system based on K-clustering classification   Order a copy of this article

    Abstract: The towing taxi-out system composed of a tractor and a civil aircraft has the structural characteristics of driving in the front and mass in the back, which leads to accidents such as lateral instability and even system "folding" when the system is steering. In this paper, a lateral stability evaluation method based on K-means cluster analysis is proposed to characterise the lateral stability state parameters of the system. The lateral stability of the system is evaluated into four grades of safety, safety hazard, potential danger and danger, and a fuzzy control-based control method is designed to control the additional lateral moment, and a differential braking method is used to achieve the lateral stability of the system. The simulation results show that the k-mean cluster analysis can achieve the hierarchical evaluation of the lateral stability of the system.
    Keywords: traffic engineering; lateral stability; K-means clustering; fuzzy control; graded control.
