Abstract

An adjustable pedal assembly is adapted to be mounted on a body structure of a motor vehicle and is operative to control a vehicle system, such as a braking system or engine throttle control system, for example. The assembly includes a carrier, a support structure mounting the carrier for fore and aft movement relative to the vehicle body structure, and a drive assembly for providing the fore and aft movement of the carrier along the support structure. A pedal is operatively connected to the carrier for movement relative to the carrier that is independent of the fore and aft movement of the carrier along the support structure. The assembly is characterized by a generator having an input associated with the pedal and an output adapted to be associated with the vehicle system. The generator is operative in response to the movement of the pedal relative to the carrier and generates an electric control signal from the output that varies in magnitude in proportion to the input by the extent of movement of the pedal relative to the carrier. The control signal is proportioned to and indicative of the position of the pedal relative to the carrier.

Dependent claims

An adjustable pedal apparatus comprising:

an adjustable accelerator pedal assembly adapted to be mounted on a body structure of a motor vehicle and operative to control an engine throttle,
an adjustable brake pedal assembly adapted to be mounted on the body structure of the vehicle and operative to control a vehicle braking system;
said adjustable accelerator pedal assembly including an accelerator carrier, an accelerator support structure mounting said accelerator carrier for fore and aft movement relative to the vehicle body structure, an accelerator drive assembly for providing said fore and aft movement of said accelerator carrier along said accelerator support structure, an accelerator pedal operatively connected to said accelerator carrier for movement relative to said accelerator carrier and independent of said fore and aft movement of said accelerator carrier along said support structure, and first generator means having an input associated with said accelerator pedal and an output adapted to be associated with the engine throttle, said first generator means operative in response to said movement of said accelerator pedal relative to said accelerator carrier to generate a first electric control signal from said output which varies in magnitude in proportion to said input by the extent of movement of said accelerator pedal relative to said accelerator carrier whereby the first control signal is proportioned to and indicative of the position of the accelerator pedal relative to the accelerator carrier;
and
said adjustable brake pedal assembly including a brake carrier, a brake support structure mounting said brake carrier for fore and aft movement relative to the vehicle body structure, a brake drive assembly for providing said fore and aft movement of said brake carrier along said brake support structure, a brake pedal operatively connected to said brake carrier for movement relative to said brake carrier and independent of said fore and aft movement of said brake carrier along said brake support structure, and second generator means having an input associated with said brake pedal and an output adapted to be associated with the braking system, said second generator means operative in response to said movement of said brake pedal relative to said brake carrier to generate a second electric control signal from said output which varies in magnitude in proportion to said input by the extent of movement of said brake pedal relative to said brake carrier whereby the second control signal is proportioned to and indicative of the position of the brake pedal relative to the brake carrier.
