Vehicle brake system with variable brake pedal feel
First Claim
1. A vehicle braking system having variable braking control for automatically adjusting brake pedal feel to accommodate the stature of an operator of the vehicle, said system comprising:
- a brake pedal assembly;
a brake pedal sensor for sensing effort applied to said brake pedal assembly and generating a signal indicative thereof;
a brake actuator for generating braking force to be applied to one or more brakes on a vehicle;
a position sensor for sensing a position characteristic of the vehicle operator which is generally indicative of stature of the vehicle operator and generating a position signal indicative thereof; and
an electronic controller for receiving the sensed brake pedal effort signal and position signal and automatically controlling the amount of braking force applied to the one or more brakes by the actuator as a function of the sensed brake pedal effort signal and the sensed position signal.

Abstract
A vehicle brake system 10 has a brake pedal assembly 14, a sensor 18 or 22 for sensing effort applied to the brake pedal assembly and a brake actuator 26 for generating braking force to be applied to one or more brakes 12A-12D on the vehicle. The brake system further includes a position sensor for sensing a position signal, such as an adjustable brake pedal position sensor 40, a seat position sensor 42, a steering wheel position sensor 44, or a driver position sensor 46, which is generally indicative of the stature and/or comfort of the driver. The brake system further includes a controller 24 for automatically controlling the amount of braking force applied to the one or more brakes in the vehicle as a function of the sensed position. Accordingly, the brake system automatically adjusts the braking effort based on a sensed position signal.

9. A method of automatically adjusting braking effort for a vehicle brake system, said method comprising the steps of:
-
sensing an amount of effort applied to a brake pedal assembly and generating a signal indicative thereof;
generating a signal representative of braking force requested by the sensed effort applied to the brake pedal assembly;
sensing a position characteristic which is generally indicative of stature of the vehicle operator; and
automatically controlling the amount of braking force applied to one or more brakes on a vehicle as a function of the sensed position characteristic and the signal indicative of the sensed amount of effort applied to the brake pedal assembly. - View Dependent Claims (10, 11, 12, 13, 14)
