Method and system for providing vehicle control to a driver

摘要

A method and system for providing vehicle control to a driver utilizes an accelerator pedal position and other various inputs. A powertrain control module uses the accelerator pedal position and the other various inputs to give the driver a combination of speed and torque control. In operating a vehicle at speeds ranging from zero to forty-five miles per hour, the powertrain controller provides the driver with torque control by mapping pedal position to electronic throttle angle according to a plurality of predetermined acceleration functions. In operating the vehicle at speeds greater than forty-five miles per hour, the powertrain controller provides the driver with speed control by mapping the electronic throttle angle according to a plurality of predetermined speed functions. Upon receiving other various inputs, the powertrain controller switches control from one form to the other.
