The present disclosure provides methods and systems for stall torque derating. Methods and systems are provided for operating a vehicle including an electric machine as a propulsion source. In one example, a motor stall assessment level is generated based on an amount of time of motor stall and an amount of torque generated by the motor. If the motor stall assessment level exceeds a threshold level or threshold, a mitigation action may be performed.

    本公开提供了“用于失速扭矩降额的方法和系统”。提供了用于操作包括作为推进源的电机的车辆的方法和系统。在一个示例中,基于马达失速的时间量和由所述马达产生的扭矩量来生成马达失速评估水平。如果所述马达失速评估水平超过阈值水平或阈值,则可以执行缓解动作。
