The embodiment of the invention provides a vehicle slip prevention method and device, electronic equipment and a readable medium, which are applied to a vehicle controller of a vehicle, according to a vehicle acceleration demand received by the vehicle and a running state of the vehicle, an expected acceleration and an expected driving torque, corresponding to the vehicle acceleration demand, of the vehicle are determined, and the vehicle slip is prevented. The driving shaft acceleration of the vehicle is obtained; if the duration that the relation between the expected acceleration and the acceleration of the driving shaft meets the preset deviation condition exceeds a preset duration threshold value, it is determined that the vehicle has the slipping risk; determining a limit coefficient of the expected driving torque based on the expected acceleration and the driving shaft acceleration; the expected driving torque is reduced through the limiting coefficient, the slipping risk of the vehicle is eliminated, hardware cost does not need to be increased, the anti-slipping capacity of the vehicle is improved only by introducing a new software algorithm, and the driving safety and comfort of the vehicle are improved.
本发明实施例提供了一种车辆打滑的防止方法、装置、电子设备及可读介质,应用于车辆的车辆控制器,根据车辆接收到的车辆加速需求以及车辆的运行状态,确定车辆的与车辆加速需求对应的期望加速度和期望驱动扭矩,并获取车辆的驱动轴加速度;若期望加速度和驱动轴加速度之间的关系满足预设偏差条件的时长超过预设时长阈值,则确定车辆存在打滑风险;基于期望加速度和驱动轴加速度,确定期望驱动扭矩的限制系数;利用限制系数减小期望驱动扭矩,消除车辆的打滑风险,无需增加硬件成本,仅通过引入新的软件算法,提升了车辆的防打滑能力,提升了车辆的驾驶安全性和舒适性。
