    摘要： An exemplary system includes at least one valve configured to control fluid flow in a dual-clutch transmission system. A solenoid is operably connected to the at least one valve and configured to move the valve to a plurality of positions. A primary processing unit is in communication with the solenoid and configured to determine an intended position of the valve. A controller is configured to receive the intended position of the valve from the primary processing unit and generate a primary control signal associated with the intended position of the valve. The solenoid is configured to move the valve to the intended position based on the primary control signal. A secondary processing unit is configured to receive information from the primary processing unit and prevent the primary control signal from controlling the solenoid if the primary processing unit is unable to control the solenoid.

    摘要： A throttle control system is presented. A throttle has a throttle actuator coupled to a throttle plate. A control module is coupled to the throttle actuator. The control module sends a first signal within a gear change time period to the throttle actuator to position the throttle plate for an increased throttle opening. The control module terminates the first signal after the gear change time period. The control module sends a second signal to the throttle actuator to position the throttle plate. The control module positions the throttle plate by the throttle actuator to attain a lower throttle opening limit. A downshift from a higher gear to a lower gear occurs.

    摘要： First and second reference voltages are applied to first and second terminals of a processor via voltage divider circuits. First and second signal conditioning circuits are coupled to third and fourth terminals of the processor, respectively, and voltage or current sensors are coupled to the first and second signal conditioning circuits. The processor measures the electrical characteristics at the third and fourth terminals and computes first and second ratiometric values of the electrical characteristics, wherein the first ratiometric value is based upon a measurement obtained from the third terminal and the first reference voltage and the second ratiometric value is based upon a measurement of obtained from the fourth terminal and the second reference voltage. The processor further identifies an issue if a ratio of the first ratiometric value to the second ratiometric value exceeds a ratio of the first reference value to the second reference value.
