Abstract
Abstract An automobile is provided with a speed control system operably connected to a drive system of the automobile. The speed control system includes an accelerator pedal assembly having an accelerator pedal movably connected to a frame of the assembly, an actuator rod connected to the accelerator pedal, and an induction sensor stationarily connected to the frame. The sensor is adapted to generate an electrical output signal corresponding to the position of the actuator rod relative to the sensor without the actuator rod contacting the sensor. The accelerator pedal assembly is connected to the chassis of the automobile as a substantially modular unit.
