Abstract

A system for limiting the speed of a vehicle includes a first module that generates a first torque signal based on a vehicle speed, a second module that generates a second torque signal based on a difference between a predetermined vehicle speed limit and the vehicle speed, and a third module that generates an output torque signal based on the first and second torque signals. The output torque signal is adapted to control the output torque of a motor.
