The invention provides a brake power assisting device for a vehicle, which comprises an input rod, a displacement sensor, a transmission mechanism, a brake master cylinder and a control unit, and the control unit is configured to control the transmission mechanism to drive the brake master cylinder to output brake fluid and establish expected brake hydraulic pressure according to a displacement value, detected by the displacement sensor, of a brake pedal. The control unit is further configured to be able to send to the regenerative braking control unit a compensation request signal requesting the regenerative braking control unit to provide compensation braking deceleration through the regenerative braking system, the compensated brake deceleration corresponds to the difference between the desired brake fluid pressure and the actual brake fluid pressure, which is generated by the deviation between the actual brake fluid amount and the theoretical brake fluid amount that the brake master cylinder needs to output in order to establish the desired brake fluid pressure. The invention further provides a regenerative braking control unit and a braking system and method of the vehicle. By means of the present invention, it is possible to reduce the additional displacement of the brake pedal required to obtain a desired brake deceleration.

    本发明提出一种用于车辆的制动助力装置,其包括输入杆、位移传感器、传动机构、制动主缸及控制单元,控制单元配置成能够根据位移传感器检测的制动踏板的位移值控制传动机构驱动制动主缸以输出制动液并建立期望的制动液压,控制单元还配置成能够向再生制动控制单元发送请求再生制动控制单元通过再生制动系统提供补偿制动减速度的补偿请求信号,补偿制动减速度对应于由制动主缸为了建立期望的制动液压而需要输出的实际制动液量与理论制动液量之间的偏差所产生的期望的制动液压与实际制动液压的差值。本发明还提出一种再生制动控制单元、一种车辆的制动系统以及制动方法。通过本发明,能够减小为获得期望的制动减速度所需的制动踏板的额外的位移。
