The invention provides a vehicle braking energy recovery control method and device and a vehicle. According to the method, when the vehicle is in a braking energy recovery state, a received downshift request of a transmission is responded, and then a power system is controlled to execute braking energy recovery according to a braking energy recovery request value sent by a chassis system; the current gear information of the transmission in the downshift process is obtained, the wheel end torque is determined based on the current gear information and the current input shaft torque, then the braking energy recovery execution value is determined according to the wheel end torque, the braking energy recovery execution value is sent to the chassis system, and the chassis system feeds back the execution result. The execution value is determined based on the actual gear shifting process information of the transmission, the accuracy of the execution value fed back to the chassis system is guaranteed, the problems of error reporting and forbidding of the braking energy recovery function in the prior art are solved, and normal operation of the function is guaranteed.
本申请提供一种车辆制动能量回收控制方法、装置及车辆,该方法在车辆处于制动能量回收状态下,对接收到的变速器的降档请求进行响应,进而根据底盘系统发送的制动能量回收请求值,控制动力系统执行制动能量回收,进一步的,获取变速器在降档过程中的当前档位信息,基于该当前档位信息以及当前输入轴扭矩,确定轮端扭矩,进而根据轮端扭矩确定制动能量回收执行值,将其发送至底盘系统,以使底盘系统反馈执行结果,实现了基于变速器实际换档过程信息确定执行值,保证了反馈至底盘系统的执行值的准确性,解决了现有技术对制动能量回收功能报错和禁用的问题,保证功能正常运行。
