A method is provided for determining the start and the end of an automatic braking process to optimize the triggering of the automatic braking process. When a set value is exceeded, an automatic braking process is triggered. The threshold value is changed as a function of the driving state, in particular, as a function of the speed of the vehicle when the brake pedal is actuated, and independently thereof, as a function of the position of the brake pedal. In addition, various criteria terminate the automatic braking process as a function of the actuation force of the brake pedal, of the speed of the vehicle and of the pedal travel.
A method for triggering an automatic braking process in a vehicle, comprising the steps of determining a threshold value of a brake pedal actuation speed by multiplying a fixed threshold value by at least one factor which is a function of a variable representative of a vehicle driving state, and using the threshold value as a single switch-on criterion for triggering of the automatic braking process, wherein a brake pressure which is greater than that which results from a brake pedal position is built up automatically after the automatic brake process is triggered.
A method for an automatic braking process in a vehicle, comprising the steps of determining a threshold value of brake pedal actuation speed in which a fixed threshold value is prescribed, determining travel of the brake pedal experienced when the fixed threshold value is exceeded, determining a travel threshold as a function of the travel of the brake pedal experienced, and triggering the automatic braking process only when the actuation speed of the brake pedal does not drop below the fixed threshold value in the time period in which the brake pedal is moved beyond the travel of the brake pedal by the travel threshold.
A method for determining a switch-off criterion for an automatic braking process in a vehicle, comprising the steps of triggering an automatic braking process after a switch-on criterion is fulfilled, building up a braking pressure, during the automatic braking process which is greater than a pressure resulting from brake pressure actuation, and terminating the automatic braking process when a speed of the vehicle drops to a value above zero and below a limit value.
