The invention provides a vehicle braking energy recovery method and device.The method comprises the steps that driving information of a second vehicle and road information in a preset journey are obtained, the distance between a first vehicle and the second vehicle is smaller than a preset threshold value, and the second vehicle is driven by the first vehicle; determining a target torque according to the driving speed, the driving information of the second vehicle and the road information in the preset distance, obtaining the state of an accelerator pedal, the state of a brake pedal and the state of vehicle control, and determining a driving intention according to the state of the accelerator pedal, the state of the brake pedal and the state of vehicle control, and according to the target torque and the driving intention, the whole vehicle demand torque is determined, and according to the whole vehicle demand torque, a motor of the vehicle is controlled to conduct braking energy recovery. According to the vehicle braking energy recovery method and device, the recovery rate of the braking energy can be increased.

    本发明提供一种车辆制动能量的回收方法和装置,该方法包括:获取第二车辆的行驶信息以及预设路程内道路信息,其中,所述第一车辆和所述第二车辆的距离小于预设阈值,根据行驶速度、第二车辆的行驶信息以及预设路程内道路信息确定目标扭矩,获取加速踏板的状态、制动踏板的状态以及车辆操控的状态,并根据所述加速踏板的状态、制动踏板的状态以及车辆操控的状态确定驾驶意图,根据所述目标扭矩和所述驾驶意图确定整车需求扭矩,根据所述整车需求扭矩控制所述车辆的电机进行制动能量回收。本发明提供的车辆制动能量的回收方法和装置可以提高制动能量的回收率。
