Abstract
A method and a device for controlling a brake system, where a braking intention value, which is used for controlling the brake system, is determined from at least one brake pedal actuation parameter. When the braking intention value is determined from the actuation parameter, its direction of change is taken into account.
Claims6
A method for controlling a brake system, comprising the steps of:
- determining at least one actuation parameter representing an actuation of a brake pedal, the at least one actuation parameter having a direction of change;
- determining a braking intention of a driver as a function of the at least one actuation parameter and the direction of change of the at least one actuation parameter;
- controlling electrically actuated actuating elements of wheel brakes as a function of the braking intention of the driver;
- wherein the braking intention is determined as a further function of a hysteresis contribution;
- and
- further comprising the step of changing the hysteresis contribution with a reversal of the direction of change of the at least one actuation parameter according to a monotone function, the monotone function being a straight line with a predefined slope.
