Abstract
In a method for providing the clamping force generated by a parking brake, the roadway incline is measured and in the case that the roadway incline exceeds a threshold value, a reengagement process is carried out after a defined time period has elapsed.
Claims21
A method for providing a clamping force generated by a parking brake and a brake device, the method comprising:
- measuring a roadway incline, wherein the measured roadway incline is categorized in one of three distinct gradient ranges;
- and
- selectively performing different control operations of the parking brake for the three distinct gradient ranges, wherein at least a time period for monitoring an unintended movement of the vehicle is varied for the three distinct gradient ranges.
A method for providing a clamping force generated by a parking brake and a brake device, the method comprising:
- performing a first engagement process to generate the clamping force by the parking brake in a vehicle while the vehicle is parked;
- after the first engagement process, determining a roadway incline;
- and
- after determining the roadway incline, performing a reengagement process by the parking brake for regenerating the clamping force,
- wherein the reengagement process is performed after a defined time period has elapsed from the first engagement process, wherein a length of the defined time period is a function of the determined roadway incline.
A regulating or control unit for providing a clamping force generated by a parking brake and a brake device, comprising:
- a determining arrangement to determine a roadway incline after a first engagement process to generate the clamping force by the parking brake in a vehicle while the vehicle is parked;
- and
- a process arrangement for:
- after determining the roadway incline, performing, if the roadway incline exceeds a threshold value, a reengagement process by the parking brake for regenerating the clamping force after a defined time period has elapsed, wherein if the roadway incline does not exceed the threshold value, no reengagement process takes place,
- wherein the roadway incline is differentiated between at least three gradient ranges, the reengagement process being performed in an upper gradient range of the at least three gradient ranges and omitted in a lowest gradient range of the at least three gradient ranges.
A parking brake, comprising:
- a regulating or control unit for providing a clamping force generated by a parking brake and a brake device, including:
- a determining arrangement to determine a roadway incline after a first engagement process to generate the clamping force by the parking brake in a vehicle while the vehicle is parked;
- and
- a process arrangement for performing, after determining the roadway incline, and if the roadway incline exceeds a threshold value, a reengagement process for regenerating the clamping force after a defined time period has elapsed, wherein if the roadway incline does not exceed the threshold value, no reengagement process takes place,
- wherein the roadway incline is differentiated between at least three gradient ranges, the reengagement process being performed in an upper gradient range of the at least three gradient ranges and omitted in a lowest gradient range of the at least three gradient ranges.
