摘要： An exemplary transmission system includes a plurality of sensors each configured to output a signal at least partially representative of a speed of at least one of a first transmission input shaft, a second transmission input shaft, a transmission output shaft, and an engine. A transmission control module is in communication with the plurality of sensors and is configured to identify at least one of the plurality of sensors as a failed sensor and another of the plurality of sensors as a working sensor. The transmission control module is further configured to estimate the signal of the failed sensor based on a predetermined relationship between an expected signal from the failed sensor and the signal received from the working sensor.

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.
