Classification: CPC B | IPC B

Claim 6:
7. A system comprising:
one or more processors configured to determine whether measured operating conditions of a vehicle system match at least one of plural different sets of designated operating conditions, the measured operating conditions of the vehicle system including a motor speed and a motor torque, the different sets of the designated operating conditions including different combinations of different designated motor speeds and different motor torques,
the one or more processors configured to determine one or more fault frequencies associated with the at least one of the different sets of the designated operating conditions that match the measured operating conditions of the vehicle system responsive to determining that the measured operating conditions of the vehicle system match at least one of the different sets of the designated operating conditions,
the one or more processors configured to determine whether a frequency peak of an alternating current (AC) that is fed to a motor of the vehicle system matches the one or more fault frequencies associated with the at least one of the different sets of the designated operating conditions that matches the measured operating conditions of the vehicle system,
the one or more processors configured to determine a mechanical fault of the motor responsive to determining that the frequency peak of the AC matches the one or more fault frequencies associated with the at least one of the different sets of the designated operating conditions,
the one or more processors configured to change movement of the vehicle system responsive to the mechanical fault being determined.
