The invention discloses a vehicle starting slip control method, system and device and a medium, and relates to the technical field of vehicle electronic starting, the method comprises the steps of determining the starting rotating speed of a to-be-controlled vehicle, judging the slip control state corresponding to the vehicle, determining the power source torque and the gearbox torque according to the slip control state and the starting rotating speed, corresponding power source rotating speed and gearbox rotating speed are determined based on the power source torque and the gearbox torque, and starting is completed according to the automobile state after the power source rotating speed and the gearbox rotating speed are the same. Sliding control and starting control can be fused, and the problems that the starting capacity is slowly recovered, and the starting time is prolonged are solved; and wheel slippage can be fully utilized to synchronize the rotating speed of the power source and the rotating speed of the gearbox, so that sliding abrasion of the clutch is reduced, and the service life of the clutch is prolonged.

    本发明公开了一种车辆起步滑移控制方法、系统、设备及介质,涉及汽车电子起步技术领域,方法包括:确定待控制汽车的起步转速,判断汽车对应的滑移控制状态,根据滑移控制状态、起步转速确定动力源扭矩以及确定变速箱扭矩,基于动力源扭矩和变速箱扭矩确定对应的动力源转速以及变速箱转速,当动力源转速以及变速箱转速相同后,根据汽车状态完成起步。本发明能够融合滑移控制与起步控制,避免起步能力恢复缓慢,延长起步时间的问题;还能充分利用车轮滑移,对动力源转速与变速箱转速的同步,减少离合器的滑磨,提高离合器的寿命。
