Abstract:
1. A transmission system for a powered vehicle, comprising: a fluid-coupling device configured to receive input torque from an engine drive shaft; an input shaft disposed along a first axis and operably coupled to the fluid-coupling device; an output shaft disposed along the first axis and configured to transfer torque to a rear axle of the vehicle; a countershaft disposed along a second axis, where the first axis and second axis are parallel but spaced from one another; a first sensor, a second sensor, and a third sensor, where the first sensor is configured to measure rotational speed of the input shaft, the second sensor is configured to measure rotational speed of the output shaft, and the third sensor is configured to measure rotational speed of the countershaft; and a controller disposed in electrical communication with the first sensor, second sensor and third sensor; wherein, the controller is configured to determine countershaft acceleration and compare the calculated acceleration to a threshold value; further wherein, based on the comparison, the controller is configured to request an adjustment in the amount of input torque being received by the fluid-coupling device.
