The invention relates to a driving motor system rotating speed fault protection method, device and system and a vehicle. The method comprises the following steps: in response to a detected rotating speed fault, carrying out rotating speed detection and judging whether the detected rotating speed is in a high-speed area or a low-speed area; when the detected rotating speed is in a low-speed area, an inertial sliding control mode is started; and when the detected rotating speed is in a high-speed area, determining an active short-circuit entering mode according to a fault signal which is reported by the driving chip and is related to a power module of the driving motor system, and starting an active short-circuit control mode based on the determined active short-circuit entering mode. According to the embodiment of the invention, an active short circuit control mode can be enabled by adopting a correct active short circuit entering mode, and the situation that a machine is burnt down is avoided.

    本申请涉及一种驱动电机系统转速故障保护方法、装置、系统和车辆。所述方法包括:响应于检测到转速故障,进行转速检测并判断检测到的转速是处于高速区或是低速区;当检测到的转速处于低速区时,启用惯性滑行控制方式;当检测到的转速处于高速区时,根据驱动芯片上报的与驱动电机系统的功率模块相关的故障信号确定主动短路进入方式,基于确定的主动短路进入方式启用主动短路控制方式。本申请实施例能够保证采用正确的主动短路进入方式来启用主动短路控制方式,避免出现机器烧毁的情况。
