Abstract
A system and method for preventing thermal damage to an electric motor in a vehicle includes arrangements for monitoring the motor and detecting a cycle of the motor. If the cycle occurred within a predetermined increment time, a cycle count is incremented. If no cycle occurs for a predetermined decrement time, the cycle count is decremented if the cycle count is greater than zero. If the cycle count is at least equal to a cycle limit, power operation of the motor is deactivated for at least the decrement time. The method may include continuously calculating energy consumed by the motor and, if the energy consumed exceeds one or more allowable energy thresholds, setting the cycle count equal to the cycle limit. The method may further include detecting a failure condition and setting the cycle count equal to the cycle limit when the failure condition is detected.
