The invention discloses an active short-circuit protection control method for coping with a motor failure, and the method specifically comprises the steps: S1, enabling a controller to enter a fault diagnosis and management module after receiving an instruction, carrying out the judgment of a fault type, and carrying out the pre-judgment of an active short circuit; s2, after the active short circuit is pre-judged, a rotary transformer of the motor is detected; s3, entering an active short-circuit judgment module, and firstly judging bus voltage and three-phase current; s4, entering an active short-circuit execution module, reading temperature according to a motor temperature module, connecting upper three bridges or lower three bridges, and executing an active short-circuit function; and S5, the rotating speed after the active short circuit is executed is detected through a rotating speed detection module, the rotating speed returns to normal, and the fault is reset. The method is directly realized through motor control software, additional hardware equipment does not need to be added, and a guarantee is provided for the safety of the controller and the whole vehicle when the motor fails.

    本发明公开了一种应对电机失效的主动短路保护控制方法,所述主动短路保护控制方法具体包括:S1,控制器接收到指令进入到故障诊断及管理模块,进行故障类型的判断,对进入主动短路进行预判断;S2,主动短路进行预判断之后,对电机的旋转变压器进行检测;S3,进入主动短路判断模块,首先对母线电压和三相电流进行判断;S4,进入主动短路执行模块,根据电机温度模块读取温度连通上三桥或下三桥,执行主动短路功能;S5,通过转速检测模块对执行了主动短路之后的转速进行检测,转速恢复正常,故障复位。本发明直接通过电机控制软件进行实现,不需要加入额外的硬件设备,在电机失效时对控制器以及整车安全提供保障。
