Abstract:
1. A system for controlling a vehicle, the system comprising: a prime mover including an output shaft; a transmission having an input shaft, a clutch assembly, a plurality of gears, a plurality of torque transmitting devices, and an output shaft, wherein the clutch assembly includes a friction clutch that rotationally couples the input shaft with the plurality of gears, and wherein the plurality of torque transmitting devices are selectively engageable with the plurality of gears to establish a plurality of speed ratios between the input shaft and the output shaft; a first sensor configured to detect a rotational speed of the input shaft of the transmission and output a first signal indicative of the speed of the input shaft of the transmission; a second sensor configured to detect a rotational speed of the output shaft of the prime mover and output a second signal indicative of the speed of the output shaft of the prime mover; a transmission controller in electronic communication with the first and second sensors and operable to control the transmission by selectively engaging the plurality of torque transmitting devices, wherein the transmission controller includes control logic comprising:
