Monitoring for malfunction of an electric motor of an electric vehicle is described. In response to malfunction, a motor controller may be shut-down to inhibit unsafe operation of the vehicle. One example provides an electric motor control apparatus configured to selectively enable or inhibit operation of an electric motor based on characteristics of a time varying signal, these characteristics may include the duty cycle, and/or the frequency content of the time varying signal. The apparatus may enable or inhibit operation of the electric motor based on the amplitude of the time varying signal in a selected frequency band. |
