ABSTRACT:
The accelerator command signal from an accelerator pedal sensor of an electric vehicle is mapped to a generally lower value in view of a reduced state of charge of the traction battery of the vehicle. The mapping requires the driver of the vehicle to depress the accelerator pedal farther to provide an equivalent accelerator command to the controller which controls the traction motor of the vehicle. The driver is thus given intuitive indication that the powertrain of his vehicle has reduced propulsive capability.
