摘要: A control for an electric motor in a vehicle. The control ascertains whether an obstacle is interfering with rotation of the motor. The control establishes a baseline speed, representing normal free running speed of the motor. This baseline speed will be different, in different operating environments. Then the control determines whether measured motor speed drops below the baseline speed by a predetermined amount. If so, then the motor is shut down, or reversed.
