The invention discloses a non-EBS platform new energy commercial vehicle composite braking strategy, which is realized based on a braking system, the braking system comprises a brake pedal, a VCU (vehicle control unit), a motor, an MCU (motor controller), a pneumatic braking system and an ABS (anti-lock braking system), the electric braking control strategy provided by the invention comprehensively considers that the wheel speed of the vehicle is not matched, namely, the control method in the working state of the ABS system. In general, motor braking energy feedback is reserved, the vehicle energy utilization rate is increased, use of vehicle traveling braking is reduced, and abrasion and heat loss of a vehicle brake are reduced; and the activation of an anti-lock braking system is considered, so that the electric braking force of the vehicle is reasonably reduced, and the braking stability and safety of the whole vehicle are improved.
本发明公开了一种非EBS平台新能源商用车复合制动策略,其基于制动系统实现,制动系统包括制动踏板、VCU(整车控制器)、电机、MCU(电机控制器)、气制动系统、ABS防抱死系统,本发明提供的电制动控制策略,综合考虑汽车处于轮速不匹配的工况下,也就是ABS系统工作状态下的控制方法:综合来说,既保留了电机制动能量回馈,提高车辆能源利用率,减少了车辆行车制动的使用,降低车辆制动器的磨损及热损耗;又考虑了防抱死系统的激活,合理减小车辆的电制动力,提高了整车制动的稳定性和安全性。
