The invention provides an electric vehicle braking optimization system and method based on braking energy recovery. The electric vehicle braking optimization system comprises an electric braking system, a hydraulic braking system, a data acquisition system and a braking operation system. The signal output end of the data acquisition system is connected to the electric braking system and the hydraulic braking system; the electric braking system comprises a whole vehicle domain controller, a motor controller and a driving motor. S2, motor single braking is executed; and S3, motor-hydraulic composite braking is executed. The hydraulic braking system and the motor braking system which are relatively independent are fully coupled through the chassis domain controller, the magnitude distribution and adjustment of hydraulic braking force and motor braking force are adjusted through the ABS/EBD system and the whole vehicle controller, motor braking is fully utilized, and energy recovery is optimized.

    本发明提供基于制动能量回收的电动汽车制动优化系统及方法,包括电制动系统、液压制动系统、数据采集系统以及制动操作系统;数据采集系统的信号输出端连接至电制动系统、液压制动系统;电制动系统包括整车域控制器、电机控制器以及驱动电机;S1、确定制动意图:S2、执行电机单制动:S3、执行电机‑液压复合制动。本发明通过底盘域控制器使液压制动系统与电机制动系统两套相对独立的系统进行充分耦合,通ABS/EBD系统及整车控制器调整液压制动力和电机制动力的大小分配及调整,充分利用电机制动,优化能量回收。
