Process and apparatus for determining the application pressures and characteristic brake values of a vehicle

Process for electronic control of a brake system of a vehicle, said vehicle having wheels and brakes at each wheel which are responsive to a driver's input, said process comprising

• monitoring said driver's input,
• monitoring at least one parameter, which decreases in response to said driver's input,
• determining the vehicle deceleration,
• determining when braking action at each wheel ends,
• determining a characteristic brake value as a function of said at least one operating parameter and said vehicle deceleration,
• storing said characteristic brake values and said at least one operating parameters determined when braking action at each wheel ends,
• controlling the brakes based on said driver's input, said stored characteristic brake values, and said at least one stored operating parameter determined when braking action at each wheel ends.

Apparatus for control of a brake system of a motor vehicle, said vehicle having wheels and brakes at each wheel which are responsive to a driver's input, said apparatus comprising

• means for increasing and decreasing an operating parameter of the vehicle as a function of said driver's input,
• means for determining at least one of a beginning of braking action during increase of said operating parameter and an end of braking action during a decrease of said operating parameter,
• means for determining a characteristic brake value during said at least one of said increase and decrease of said operating parameter, and
• means for controlling the brakes based on said driver's input, said characteristic brake values, and at least one of said beginning of braking action and said end of braking action.
