The invention relates to a deceleration anti-slip control method and device, a medium, equipment and a vehicle, the deceleration anti-slip control method is characterized in that an anti-slip control stage is divided into a torque-up control stage and a torque-up recovery stage, different torque control strategies are executed in different anti-slip control stages, and the torque-up recovery stage is improved by improving the electric feedback torque in the torque-up control stage. In other words, the braking force applied to the wheels is reduced, so that the purpose of restraining vehicle braking slippage is achieved, and the vehicle stability is met; in the torque rising recovery stage, the vehicle braking slippage is restrained, the electric feedback torque is controlled to be recovered to the target required torque of the driver, namely the braking force applied to the wheels is increased, so that the vehicle deceleration performance is met, and the stability and the deceleration performance of the vehicle during deceleration slippage are both considered.
本公开涉及减速防滑控制方法、装置、介质、设备及车辆,该减速防滑控制方法通过将防滑控制阶段细化为升扭控制阶段和升扭恢复阶段,在不同防滑控制阶段执行不同的扭矩控制策略,在升扭控制阶段通过提高电回馈扭矩,即减小施加在车轮上的制动力,以到达抑制住车辆制动滑移的目的,满足车辆稳定性;在升扭恢复阶段,车辆制动滑移已被抑制住,通过控制电回馈扭矩恢复到驾驶员目标需求扭矩,即增大施加在车轮上的制动力,以满足车辆减速性能,从而兼顾车辆减速打滑时的稳定性和减速性能。
