Abstract
A drive system for an electric vehicle includes a motor for providing a drive torque and an electrically actuated brake for providing a braking torque to the motor. The system includes a controller that receives a plurality of inputs which may include a battery voltage input, a throttle pedal position input, a brake pedal position input, a key switch input, a forward/neutral/reverse (FNR) input, and a brake full-stroke input in addition to the brake pedal input. The controller may generate a drive signal for the motor based on some or all of the inputs.
