The invention provides a vehicle operation mode switching method and device and an automobile, and relates to the field of automobile control. The method comprises the steps that a hybrid power mode request is received, and whether the rotating speed difference between the two ends of a synchronizer exceeds a calibration value or not is judged; acquiring a current running mode of the vehicle, and requesting a transmission control unit to perform clutch control according to the current running mode of the vehicle so as to reduce the rotating speed difference; and when it is detected that the rotating speed difference is smaller than or equal to the calibration value, a hybrid power mode switching instruction is sent to a transmission control unit, so that the vehicle runs in a hybrid power mode. According to the invention, the purpose of switching the hybrid power mode without reducing the vehicle speed at a high speed of the vehicle is achieved. The driving performance is improved, meanwhile, the experience feeling of a user is improved, and the high practical value is achieved.

    本发明提供了一种车辆运行模式切换的方法、装置以及一种汽车,涉及汽车控制领域。所述方法包括:接收混合动力模式请求,判断同步器两端的转速差是否超过标定值;获取车辆当前运行模式,并根据车辆当前运行模式,请求变速器控制单元进行离合器控制,以降低转速差;在检测到转速差小于或等于标定值时,向变速器控制单元发送混合动力模式切换指令,以使得车辆在混合动力模式下运行。本发明达到了车辆较高速度下不需要降低车速即可切换混合动力模式的目标。提升了驾驶性能的同时,提高了用户的体验感,具有较高的实用性价值。
