According to the upshift speed regulation method and system and the vehicle, when the scheme is implemented, the vehicle speed of the vehicle is detected in real time, when it is detected that the vehicle has an upshift requirement, the output torque of a motor is controlled to be zero, when the output torque of the motor is zero, a transmission is controlled to disengage from a gear, then whether the electric quantity of a power supply battery is larger than a full electricity threshold value or not is judged, and the vehicle is started; when the current value is larger than the full-power threshold value, the motor controller is controlled to be switched into a three-phase active short-circuit mode to adjust the speed of the motor, so that the rotating speed of the motor reaches the target rotating speed, and after the rotating speed of the motor reaches the target rotating speed, the transmission is controlled to execute the gear shifting action, and upshift speed adjustment of the vehicle is achieved; the problem that the battery is damaged due to the fact that energy feedback is generated by adopting conventional rotating speed ring speed regulation in the full-charge state of the automobile battery is solved.

    本发明提供一种升挡调速方法、系统和车辆,方案在实施时,实时对车辆的车速进行检测,当检测到车辆有升挡需求时,控制电机输出扭矩为零,当电机输出扭矩为零时,控制变速器摘挡,然后判断供电电池的电量是否大于满电阈值,当大于满电阈值时,控制电机控制器切换成三相主动短路模式对电机进行调速,使得电机转速达到目标转速,当电机转速达到所述目标转速后,控制变速器执行换挡动作,实现了车辆的升挡调速,并且,解决了汽车电池满电状态下因采用常规转速环调速产生能量回馈而对电池造成伤害的问题。
