Electric heavy commercial road vehicles use a regenerative brake system that acts on pressing of brake pedals and co-operates with friction brakes to provide the necessary deceleration. The strategy of applying regenerative braking during accelerator pedal release and its control using accelerator pedal position in the dead zone is focused in this work. It is observed that implementation of this strategy in heavy road vehicles used for urban drive applications has the advantage that under most of the driving conditions, the deceleration requirement is within 0.15 m/s2 and only pure regenerative braking provided with accelerator pedal release is sufficient. This strategy combined with the use of braking by pressing the brake pedal can meet the entire range of deceleration requirements of a vehicle. The results show that higher amount of energy recovery and driving comfort can be achieved with this feature. Further, this strategy is integrated with the complete VCU model and the analysis of different methods of applying regeneration torque viz. constant torque, increasing torque at different rates etc., amount of dead zone to be provided in accelerator pedal and their effect on vehicle speed, deceleration and energy recovery are studied.
