摘要

A method for a vehicle having plural electric motors includes generating motor electrical signatures for the motors. The motor electrical signatures represent one or more characteristics of electrical energy that is supplied to the motors. The method also includes identifying one or more fault measures of each of the motor electrical signatures. The fault measures are indicative of mechanical characteristics of the motors. The method further includes comparing the one or more fault measures of each motor with the one or more fault measures of the other motors in the same vehicle and predicting an impending mechanical failure of one or more of the motors based on comparing the fault measures of the motors.
