The invention relates to a vehicle mode switching control method and system, a vehicle and a computer readable storage medium. The method comprises the steps that in response to a first vehicle mode switching request for switching from a two-wheel drive mode to a four-wheel drive mode, the motor rotating speed and the motor torque of a first motor are adjusted, and under the condition that the motor rotating speed and the motor torque meet clutch intervention conditions, the rotating speed difference value between the motor rotating speed and the shaft speed of a first shaft is monitored in real time; and when the rotating speed difference value meets the preset gear shifting condition, the clutch is controlled to shift, so that the first motor and the first shaft are switched from the separation state to the matched connection state. By means of the method, vehicle mode switching is achieved through clutch control, and timeliness of mode switching is improved.
本申请涉及一种车辆模式切换控制方法、系统、车辆和计算机可读存储介质。所述方法包括:响应于从两驱模式切换至四驱模式的第一车辆模式切换请求,对第一电机的电机转速和电机扭矩进行调整,在电机转速和电机扭矩满足离合器介入条件的情况下,实时监测电机转速和第一轴轴速之间的转速差值;当转速差值满足预设进档条件时,控制离合器进档,以使第一电机和第一轴从分离状态切换至配接状态。采用本方法利用离合器控制实现车辆模式切换,提高了模式切换的及时性。
