Article: Optimisation of pulse and glide technique to enhance the energy saving control methodology in low power utility vehicle Journal: International Journal of Vehicle Performance (IJVP) 2026 Vol.12 No.3 pp.299 - 319 Abstract: Autonomous connected vehicles execute complex algorithms with or without driver interventions to implement fuel-saving methods of driving. One such energy-saving drive mode, pulse and glide (<i>PnG</i>) is redefined and a suitable methodology is proposed for evaluating its effect during real-time driving conditions. Various parameters like acceleration, velocity changes, city driving, highway driving, load and other dynamic factors are experimentally studied at different operating conditions. Key parameters influencing the energy-saving method are identified and the relation between them is analysed by data-driven approach. Optimisation of the energy saving parameters is executed, framed as an algorithm and evaluated on Indian road conditions. Significant improvement in fuel saving by up to 16% is achieved for four-wheeler passenger car in highway and almost negligible saving in city. Energy assessment driving cycle for automation test is arrived for vehicles powered by electrical energy and internal combustion engine.

Abstract: Autonomous connected vehicles execute complex algorithms with or without driver interventions to implement fuel-saving methods of driving. One such energy-saving drive mode, pulse and glide (PnG) is redefined and a suitable methodology is proposed for evaluating its effect during real-time driving conditions. Various parameters like acceleration, velocity changes, city driving, highway driving, load and other dynamic factors are experimentally studied at different operating conditions. Key parameters influencing the energy-saving method are identified and the relation between them is analysed by data-driven approach. Optimisation of the energy saving parameters is executed, framed as an algorithm and evaluated on Indian road conditions. Significant improvement in fuel saving by up to 16% is achieved for four-wheeler passenger car in highway and almost negligible saving in city. Energy assessment driving cycle for automation test is arrived for vehicles powered by electrical energy and internal combustion engine.
