The invention relates to an energy recovery method and device, vehicle-mounted equipment and a vehicle, and the method comprises the steps: obtaining the driving state data of the vehicle, determining the current gradient of the position where the vehicle is located based on the driving state data, comparing the current gradient with a preset gradient threshold value, and determining the energy recovery intensity of the vehicle according to the comparison result. The target torque of the motor is determined by combining the energy recovery intensity, the preset minimum energy recovery torque and the preset maximum energy recovery torque, and the motor is controlled to operate according to the target torque so as to perform energy recovery on the vehicle; according to the method, the influence of the gradient factor on the recovery strength is fully considered, the energy recovery strength of the vehicle is determined according to the current gradient of the position where the vehicle is located, the target torque of the motor is determined by combining the energy recovery strength, the preset minimum energy recovery torque and the preset maximum energy recovery torque, and the precision of the recovery strength and the precision of the target torque are improved.

    本发明涉及一种能量回收方法、装置、车载设备及车辆,该方法通过获取车辆的行驶状态数据,基于行驶状态数据,确定车辆所处位置的当前坡度,将当前坡度与预设坡度阈值进行比较,并根据比较结果,确定车辆的能量回收强度,结合能量回收强度、预设最低能量回收扭矩和预设最高能量回收扭矩,确定电机的目标扭矩,并控制电机按照目标扭矩进行运行,以对车辆进行能量回收;本发明充分考虑到坡度因素对回收强度的影响,根据车辆所处位置的当前坡度确定车辆的能量回收强度,并结合能量回收强度、预设最低能量回收扭矩和预设最高能量回收扭矩,确定电机的目标扭矩,提高回收强度和目标扭矩的精确度。
