    摘要: A hybrid electric vehicle (HEV) has an algorithm for executing a method for diagnosing a high-voltage (HV) fault condition aboard the HEV. The HEV includes a high-voltage (HV) battery, an auxiliary power module (APM), a power inverter module (PIM), and a three-phase motor/generator unit (MGU). A controller executes the method to thereby measure a DC output current from the HV battery, a DC inlet current into the APM, and a pair of AC phase currents in the MGU. The method further includes calculating a DC inlet current into the PIM using the AC phase currents, diagnosing the HV fault condition using the DC output currents and the DC inlet currents, and executing a control action in response to the diagnosed condition. The method can include shutting off the APM to determine whether the APM is the root cause of the HV fault condition.

    摘要: A method and an article of manufacture are provided to monitor a temperature sensing circuit and detect a fault therein. The method comprises monitoring sensor readings output from a plurality of temperature sensing circuits. An average sensor reading is determined, calculated from the sensor readings output from a subset of the temperature sensing circuits. Each of the sensor readings is compared to the average sensor reading. A fault is identified when one of the sensor readings deviates from the average sensor reading by an amount greater than a threshold, more particularly when one of the sensor readings deviates from the average sensor reading by an amount greater than the threshold at least a quantity of X times out of Y sensor readings.

    摘要: A rear wheel steering mechanism capable of independently positioning the rear wheels of a vehicle also independently corrects the toe error of each steered wheel. In the preferred embodiment, each rear wheel is steered by a separate actuator. The overall steering command for the actuators is determined at least in relation to the front steering angle, the command being constrained within predefined command limits. The actuators, on the other hand, have a control range which exceeds that of the predefined command limits. The controller which generates the steering commands is adapted to receive and store signals representing the toe error of each rear wheel from a conventional wheel alignment machine, and the controller causes the actuator to position each rear wheel as a combined function of the steering command and the respective stored toe error signals. When realignment becomes necessary, an alignment machine is connected to the controller, and the system enters a reset mode in which the rear wheels are steered to a "straight ahead" position independent of the previously stored toe error values, and the newly measured toe error values are stored for future steering control.
