Abstract
A braking control system includes sensors for detecting pressure applied to a brake pedal. The system can also include a pressure sensor capable of detecting the hydraulic pressure of the braking system. The system can also include a position sensor for detecting a position of the brake pedal. The pressure applied to the brake pedal is compared to either the hydraulic pressure or the pedal position. If the resulting measurements are not correlated properly, braking countermeasures are applied. Braking countermeasures can include engine braking, regenerative braking, hydraulic assist, and brake pad assist.
Claims23
A method of controlling braking in a motor vehicle, comprising:
- receiving information related to the hydraulic pressure of a braking system;
- receiving information related to the pressure applied to a surface of a brake pedal;
- determining a measured braking relationship between the hydraulic pressure of the braking system and the pressure applied to the surface of the brake pedal;
- retrieving a predetermined braking relationship, wherein the predetermined braking relationship comprises a predetermined correlation between the hydraulic pressure of the braking system and the pressure applied to the surface of the brake pedal;
- comparing the measured braking relationship and predetermined braking relationship;
- and
- activating a braking countermeasure when the measured braking relationship is substantially different from the predetermined braking relationship, the braking countermeasure being configured to reduce a speed of the motor vehicle.

A method of controlling a braking system in a motor vehicle, comprising:
- sensing a pressure applied to a brake pedal surface;
- receiving information related to the amount of braking force applied by a braking system;
- determining if the pressure applied to the brake pedal surface agrees with the amount of braking force applied by the braking system;
- and
- applying a braking countermeasure if the pressure applied to the brake pedal does not agree with the amount of braking force applied by the braking system.
