A vehicle propulsion system includes a prime mover having a prime mover output shaft, a continuously variable transmission having a variator input shaft coupled to the prime mover output shaft and having a variator output shaft, a driver torque request module in communication with a driver input and for outputting a driver torque request, an engine backbone in communication with the prime mover, and a transmission backbone in communication with the continuously variable transmission and the engine backbone in the vehicle propulsion system. The transmission backbone includes a positive torque request module that generates a positive torque request, and a positive torque request monitor that limits a torque request from the transmission backbone to the engine backbone to a maximum of a predetermined threshold.
A vehicle propulsion system, the system comprising:
A controller for a vehicle propulsion system in a vehicle, the controller comprising:
A method for controlling a vehicle propulsion system which includes a prime mover having a prime mover output shaft, a continuously variable transmission having a variator input shaft coupled to the prime mover output shaft and having a variator output shaft, the method comprising:
