发明名称 ACTUATOR TORQUE PRODUCTION DIAGNOSTIC
摘要 An example hybrid vehicle includes a control unit that generates a control signal representing an expected torque, a first actuator that generates a first torque, a second actuator that generates a second torque associated with operating characteristics of the second actuator, and a gearbox that can receive the torque generated by the first and second actuators. A controller can determine whether the first torque produced by the first actuator is substantially the same as the expected torque based on one or more operating characteristics of the second actuator. An example method includes deriving an actual torque of the first actuator based on the operating characteristics of the second actuator, defining a torque deviation from the actuator torque and the expected torque, comparing the torque deviation to a calibration threshold, and diagnosing that the first actuator has failed if the torque deviation exceeds the calibration threshold.
