Abstract:
1. A method for controlling a transmission assembly of a vehicle, the method comprising: providing a vehicle having a first power source and a second power source in parallel with the first power source, the first power source including a prime mover and a transmission assembly, the transmission assembly including a torque converter that is coupled to the prime mover, the transmission assembly further including a clutch that selectively engages the torque converter to a transmission of the transmission assembly, the second power source including a pump-motor unit, a fluid reservoir, and an energy storage unit; comparing a torque value of the second power source to a torque threshold value; disengaging the clutch of the transmission assembly so that the torque converter of the transmission assembly is disengaged from the transmission of the transmission assembly when the torque value of the second power source is greater than or equal to the torque threshold value.
