The invention relates to the technical field of vehicle control, in particular to a switching method for vehicle driving modes, a processor, a system and a vehicle. The switching method comprises the following steps: when the vehicle is in a limping mode, acquiring a first operation parameter of the vehicle; when it is determined that the running state of the vehicle meets a first condition according to the first running parameter, the current first demand torque of the vehicle, the real-time rotating speed of a driving motor and an accelerator pedal signal input by a user are obtained; periodically adding a preset value on the basis of the first demand torque to serve as a second demand torque of the vehicle; a first target demand torque of the vehicle is determined according to the real-time rotating speed of the driving motor and the accelerator pedal signal, and the first target demand torque is a real-time change value; under the condition that the second demand torque is larger than or equal to the first target demand torque, increasing of the demand torque of the vehicle is stopped; and the first target demand torque serves as the demand torque of the vehicle, so that the vehicle exits the limping mode.

    本申请涉及车辆控制技术领域,具体涉及一种用于车辆行驶模式的切换方法、处理器、系统及车辆。切换方法包括:在车辆处于跛行模式下,获取车辆的第一运行参数;在根据第一运行参数确定车辆的运行状态满足第一条件的情况下,获取车辆当前的第一需求扭矩、驱动电机的实时转速以及用户输入的加速踏板信号;周期性地在第一需求扭矩的基础上增加预设数值,以作为车辆的第二需求扭矩;根据驱动电机的实时转速和加速踏板信号确定车辆的第一目标需求扭矩,其中,第一目标需求扭矩为实时变化值;在第二需求扭矩大于或等于第一目标需求扭矩的情况下,停止增加车辆的需求扭矩;将第一目标需求扭矩作为车辆的需求扭矩,以使车辆退出跛行模式。
