Abstract
A method of distributing a torque demand in a hybrid electric vehicle having an internal combustion engine and an electric motor is provided. In hybrid operation, the motor initially starts the vehicle. When the vehicle desired power demand reaches a first vehicle operational parameter, a controller switches the torque demand to the engine . An accelerator pedal has a position sensor which determines a non-fixed pedal first position during transition between the motor and engine . The accelerator pedal also has a preset second position wherein a maximum of engine torque is requested. The controller , cognizant of the accelerator pedal first and second positions, linearly scales the accelerator pedal to provide a uniform torque-responsive accelerator pedal.
