ABSTRACT:
A vehicle and a method for controlling a vehicle transmission is provided. The vehicle has at least one wheel and a positionable acceleration device. The vehicle includes an engine being responsive to the position of the acceleration device, wherein the engine provides torque to the wheel. In one embodiment, a transmission is coupled to the engine and the wheel, wherein the transmission provides multiple speed ratios and is configured to operate in a continuously variable mode. The vehicle also includes a controller that communicates with the engine and the transmission. The controller senses the position of the acceleration device, determine a shift schedule based on the position of the acceleration device, and set an engine speed limit for the engine. The controller also generates signals for the transmission to provide the speed ratio based on the engine speed limit while the transmission operates in the continuously variable mode.
