Intelligent braking system and method
First Claim
1. A system comprising:
- a processor coupled to a vehicle;
a brake controller coupled to the processor;
a first range detector coupled to the processor;
wherein the processor executes instructions to operate the brake controller based on a comparison of a deceleration profile with range data from the first range detector and a speed of the vehicle.

Abstract
A distance, speed and direction sensitive processor coupled to a brake controller. The processor executes instructions to compare actual vehicle performance with that of a deceleration profile and modulates the brake controller to bring vehicle performance into agreement with the profile. Distance information is provided by a radar sensor for long ranges, an ultrasonic sensor for medium ranges, and a wheel rotation sensor for short ranges. Speed information is provided by a vehicle mounted sensor or calculated by the processor based on distance. Direction information is provided by a vehicle mounted switch or determined by the processor based on distance. The brake controller includes a hold valve and a dump valve, each of which is modulated with a pulse train signal.
