  • Patent number: 9132812
    Abstract: A method and a brake system, in which method a vehicle having a service brake and a parking brake is held by autonomous brake actuation, wherein in a first step, an actuation of the service brake is performed, and in the event of a predefined condition being met, a transfer from the service brake to the parking brake takes place. According to an aspect of the invention, during the transfer, both an actuation of the parking brake and also an additional actuation of the service brake takes place.
    Type: Grant

  • Patent number: 8224548
    Abstract: Disclosed is a method of preventing a vehicle in a starting maneuver from rolling in a direction opposite a direction selected to move the vehicle during the starting maneuver. A brake force is built up or maintained on at least one wheel brake during standstill of the vehicle. The method is characterized in that a comparison between an engine rotational speed gradient and an engine rotational speed gradient threshold value as well as a comparison between a pedal travel, by which an accelerator pedal of the vehicle is depressed, and a pedal travel threshold value are performed, and in that the brake force at the at least one wheel brake is reduced when it is established that the engine rotational speed gradient exceeds the engine rotational speed gradient threshold value, and/or the pedal travel, by which the accelerator pedal is depressed, exceeds the pedal travel threshold value. Also disclosed a device that is appropriate to implement the method.
