Brake system for motor vehicles

The motor vehicle brake system having a brake pedal, a brake booster, a master brake cylinder and an electronically regulatable brake unit arranged between the master brake cylinder and wheel brakes of the vehicle, comprising:

• an electronic control unit adjusting a brake pressure in the wheel brakes independently of a preliminary pressure existing at an output of the master brake cylinder;
• wherein the electronic control unit senses a deceleration course achieved by the brake booster as a function of a pedal operating value directly proportional to a pedal force applied by a driver via a brake pedal;
• and
• further wherein the electronically regulatable brake unit generates the brake pressure in the wheel brakes such that a desired deceleration course corresponding to a desired characteristic deceleration curve stored in the electronic control unit occurs when an actual deceleration course deviates from the desired deceleration course.

A software product for controlling a motor vehicle brake system having a brake pedal, a brake booster, a master brake cylinder, an electronic control unit and an electronically regulatable brake unit, the software product comprising:

• a computer readable medium having stored thereon code segments that:
• sense a course of a pedal operating value achieved by the brake booster which is directly proportional to a pedal force applied by a driver via a brake pedal;
• and
• when a predetermined threshold value of the pedal operating value is reached, generate a brake pressure signal for the wheel brakes to the electronically regulatable brake unit such that a raised deceleration gradient occurs over a course of the deceleration with a further rise of the pedal operating value.
