Abstract
A method and system for automatic braking is described. A service brake which can be operated electrically with a compressed air pressure and a parking brake which can be operated electrically are provided. When the vehicle stops due to the service brake being applied, the service brake is released and the parking brake is applied as a function of a release criterion. The release criterion includes the parking brake not being applicable manually because of a defect, and the operation of a control element for application of the parking brake.
Claims11
1-11. (canceled)
Method for automatic braking, without active braking operation by a driver, of a vehicle equipped with an electronically controlled braking device, including a service brake operable electrically and to which is applicable a service braking pressure pB, and a parking brake operable electrically and to which is applicable a parking braking pressure pF, comprising the acts of:
- starting from the vehicle being stationary as a result of the service brake being applied, releasing the service brake and applying the parking brake as a function of a release criterion;
- initiating without delay application of the parking brake in response to the initiation criterion;
- and
- selecting the initiation criterion to be at least one of the parking brake not being applicable manually because of a defect, and operation of a control element for application of the parking brake.
Method according to claim 1, wherein, when the braking effect of the parking brake is not sufficient to prevent the vehicle from rolling, the service brake is applied again, and at least one of an audible and visual warning signal is produced.
