    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： A method and system for controlling downshifting in an automated mechanical transmission system (10) utilized on a vehicle. When an automatic power downshift from a currently engaged ratio (GR) is required, the engine acceleration (EA) is monitored and compared with an engine free acceleration (EFA) to detect a false Neutral condition and to take appropriate action accordingly. Alternatively, a false Neutral condition is detected when the Absolute Value of the rotational speed of the output shaft (OS) times the currently engaged gear ratio (GR) minus the rotational speed of the input shaft (IS) is less than a predetermined value (ABS((OS*GR)−IS)).
