Embodiment Construction

[0017] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout, and prime notation is used to indicate like elements in alternate embodiments.

[0018] refer to Figure 1 to Figure 3 , a brake intensity indicator system 20 for a vehicle 21 of the type comprising a service brake pedal 22 within a footwell 24 and a plurality of brake lights 23a-23c. The brake lights 23a-23c are typically carried by the vehicle and face rearwardly, with at least one of the brake lights being in the rear window. Of course, other ...

Abstract

A braking intensity indicator system for a vehicle of a type that includes a foot operated brake pedal and at least one brake light may include a proximity sensor to be associated with the brake pedal and a controller. The controller may be configured to cooperate with the proximity sensor to determine a plurality of brake pedal positions versus time during foot operation of the brake pedal, and selectively adjust an intensity of the at least one brake light based upon the determined plurality of brake pedal positions versus time.

Description

technical field [0001] The present invention relates to vehicles, and more particularly to vehicles having a service brake pedal and related methods. Background technique [0002] To increase safety and driver awareness, especially during vehicle operation after dark, vehicles are often equipped with lights. Headlights for forward lighting, parking lights, and brake pedal lights are some of the types of lights in a car. The brake pedal light is normally activated when the vehicle's foot brake pedal is operated. [0003] Some brake lights only activate when the brake pedal is depressed, and usually don't give any indication of how fast or how far the brake pedal is being depressed. This may lead to an increased number of rear-end collisions, as drivers following the vehicle may not be aware of how fast or how hard the brake pedal is being depressed. [0004] To improve driver perception, some braking systems provide an indication of braking intensity. For example, such a ...
