Abstract: In this paper, the design and development cycle for integrated systems architecture for External Speed Adaptation (ESA) and Collision Avoidance Systems (CAS) is presented. It subsequently presents a new method of modelling the integrated system architecture based on structured analysis. Moreover, a vehicle kinematics model is developed and used as the basis for designing the systems decision logic. A description of an experimental hardware and CAN software simulation show the potential of the systems integration. In the experimental system, the speed limiter (vehicle throttle control and ECU) is a mechatronic sub-system and the collision avoidance system that deactivates the acceleration of the truck and controls the speed of the truck to a preset speed limit to avoid collision. This is based on communication between a roadside sensor and the vehicle and an interface between the collision avoidance and speed adaptation systems.
Keywords: collision avoidance; integrated safety; intelligent trucks; speed adaptation; systems integration; vehicle kinematics; modelling; mechatronics.
