Abstract
A vehicle includes an engine, input clutch, transmission, and controller. The transmission includes an input member, output member, and bidirectional speed sensor. The speed sensor measures a magnitude and direction of a rotational speed of the output member. Engagement of the input clutch selectively connects the engine to the input member. The controller has a commanded gear shift monitoring (CGSM) module. The CGSM module executes a method via a processor to cause the controller to detect a requested shift of the transmission to a destination gear, and to receive the measured magnitude and direction from the speed sensor. The controller determines a calibrated maximum output speed for the destination gear using the measured magnitude and direction, and executes a control action with respect to the transmission when the measured magnitude exceeds the calibrated maximum output speed. A transmission assembly includes the transmission and controller.
