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.
