The invention discloses a vehicle starting control method, device and equipment and a storage medium. The method comprises the steps that current state information of a vehicle is obtained, and whether the vehicle is in a pure electric starting mode or not is detected based on the current state information; if in the pure electric starting mode, a target rotating speed is determined based on the current accelerator pedal opening degree, a target rotating speed request is made for a motor, so that the motor conducts closed-loop control based on the target rotating speed, the current output torque of the motor is obtained, and a clutch is controlled to conduct open-loop control based on the current output torque; and the current rotating speed difference value between the current rotating speed of the motor and the current rotating speed of the clutch is determined, and when the current rotating speed difference value is smaller than a first preset difference value, the clutch is pressurized based on the preset pressure rate. By means of the technical scheme, rapid and smooth starting control over the vehicle can be achieved, the control precision of the clutch is improved, the problem that rotation speed fluctuation is generated during starting of a traditional vehicle is solved, and the vehicle driving performance is improved.

    本发明公开了一种车辆起步控制方法、装置、设备和存储介质。该方法包括:获取车辆的当前状态信息,基于当前状态信息检测车辆当前是否处于纯电动起步模式;若处于纯电动起步模式,则基于当前油门踏板开度确定目标转速,并对电机进行目标转速请求,以使电机基于目标转速进行闭环控制,获取电机的当前输出扭矩,并控制离合器基于当前输出扭矩进行开环控制,确定电机的当前转速与离合器的当前转速之间的当前转速差值,并在当前转速差值小于第一预设差值时,基于预设压力速率,对离合器进行加压处理。通过本发明实施例的技术方案,可以实现车辆快速、平顺的起步控制,提高离合器的控制精度,避免传统车辆起步产生转速波动的问题,提升车辆驾驶性能。
