Study on Adaptive Cruise Control Strategy for Pure Electric Vehicle Considering Braking Energy Recovery Sheng Zhang , Xiangtao Zhuan

Abstract

This paper studies the control strategy for adaptive cruise control (ACC) system on pure electric vehicle (PEV) in the car-following process. The hierarchical control structure is adopted for the ACC system, and the structure contains upper controller and lower controller. In the upper controller, multiple objectives including the safety, tracking, comfort and energy consumption are optimized in a model predictive control (MPC) framework. In the lower controller, the energy is recovered during braking. So the energy economy is improved by reducing energy consumption and increasing energy recovery. The proposed ACC control strategy is evaluated in simulation. The simulation results show that safety and tracking are guaranteed, and the comfort and energy economy are improved significantly.
