The invention provides a sliding energy recovery compensation method and device and an electric vehicle. The method comprises the steps that when the electric vehicle is in a gear sliding state, the maximum reverse dragging torque currently provided by a driving motor is smaller than the preset sliding reverse dragging torque, and an electronic brake has the braking capacity; and the driving motor controller sends a brake compensation starting request to the electronic brake, the brake compensation starting request comprises the first sliding compensation torque, and the first sliding compensation torque is the difference obtained by subtracting the maximum reverse dragging torque from the preset sliding reverse dragging torque, so that the electronic brake conducts braking with the first sliding compensation torque as the target torque. Therefore, when the driving motor cannot provide the preset sliding reverse dragging torque, corresponding compensation is carried out through the electronic brake, so that the deceleration consistency of the electric vehicle is kept under different sliding working conditions, and the user experience is improved.
本发明提供了一种滑行能量回收补偿方法、装置及电动车辆,方法包括在电动车辆处于带档滑行状态、驱动电机当前可提供的最大反拖力矩小于预设的滑行反拖力矩以及电子制动器具备制动能力时,驱动电机控制器向电子制动器发送开启制动补偿请求,开启制动补偿请求包含第一滑行补偿力矩,第一滑行补偿力矩为预设的滑行反拖力矩减去最大反拖力矩的差,以使电子制动器将第一滑行补偿力矩作为目标力矩进行制动。这样在驱动电机无法提供预设的滑行反拖力矩时,通过电子制动器进行相应补偿,使得在不同滑行工况时保持电动车辆减速度的一致性,改善了用户体验。
