The invention relates to optimization of regenerative braking. A control system for controlling a powertrain of an electric or hybrid electric vehicle is disclosed. The powertrain includes a battery and a traction motor and is operable in a regenerative braking mode. The control system is configured to generate a deceleration target of the vehicle in the regenerative braking mode and generate a torque command for the traction motor based on the deceleration target. By generating a deceleration target for the vehicle during regenerative braking and using the deceleration target to control the torque of the traction motor, more consistent regenerative braking may be provided, particularly when the vehicle is used to carry different loads.
本公开涉及优化再生制动。公开了一种用于控制电动车辆或混合动力电动车辆的动力总成的控制系统。动力总成包括电池和牵引马达并且可在再生制动模式下操作。控制系统被配置成生成再生制动模式下的车辆的减速度目标,并且基于减速度目标生成用于牵引马达的扭矩命令。通过在再生制动期间为车辆生成减速度目标并使用减速度目标来控制牵引马达的扭矩,可以提供更一致的再生制动,特别是当车辆用于承载不同负载时。
