Driver assistance system with reduced activation time

1. A method for the operation of an automated parking brake of a motor vehicle including a hydraulic operating brake and an automated parking brake, the parking brake configured to adopt at least a disengaged position, an engaged position, and an intermediate position between the disengaged position and the engaged position, the method comprising:

determining the intermediate position such that the parking brake produces a lesser braking effect compared to the engaged position of the parking brake;

determining a parking variable representing a parking process of the motor vehicle with a control unit; and

bringing the parking brake into the intermediate position in response to determining the parking variable.

2. The method according to claim 1 , wherein determining the parking variable comprises:

carrying out an analysis of at least one of a geographic location of the motor vehicle and a map material.

3. The method according to claim 1 , wherein determining the parking variable comprises:

carrying out an analysis of at least one of video data, data of sound-based and/or radar-based systems, vehicle functions, and activation of a parking aid and/or an automated parking function.

4. The method according to claim 1 , wherein determining the parking variable comprises:

carrying out an analysis of at least one of a speed profile of the motor vehicle, an operation of a turn indicator, and a wheel angle and/or a steering angle.

5. The method according to claim 1 , further comprising:

determining the intermediate position such that a frictional torque is produced by the parking brake, but a mobility of the mobility vehicle is maintained.

6. The method according to claim 1 , further comprising:

checking operability of the parking brake while the parking brake is brought into the intermediate position.

7. The method according to claim 1 , further comprising:

immediately applying a required brake force with the parking brake in response to a recognition of a requirement to park.

8. The method according to claim 1 , further comprising:

immediately activating the parking brake and further activating the parking brake until the engaged position of the parking brake is reached in response to recognizing a final parking position of the motor vehicle.

9. The method according to claim 1 , further comprising:

setting at least two different activation strategies for the parking brake,

wherein a first activation strategy brings the parking brake directly from the disengaged position into the engaged position,

wherein in a second activation strategy an intermediate position is additionally activated, and

wherein selection of the activation strategy is carried out depending on recognition of the parking variable representing the parking process of the motor vehicle.

10. A method for the operation of an automated parking brake of a motor vehicle including a hydraulic operating brake and an automated parking brake, the parking brake configured to adopt at least a disengaged position, an engaged position, and an intermediate position between the disengaged position and the engaged position, the method comprising:

determining the intermediate position such that a shorter activation time is necessary in order to change the parking brake to the engaged position compared to the disengaged position of the parking brake;

determining a parking variable representing a parking process of the motor vehicle with a control unit; and

bringing the parking brake into the intermediate position in response to determining the parking variable.

11. A method for the operation of an automated parking brake of a motor vehicle including a hydraulic operating brake and an automated parking brake, the parking brake configured to adopt at least a disengaged position, an engaged position, and an intermediate position between the disengaged position and the engaged position, the method comprising:

determining the intermediate position such that a significant part of a free travel of the parking brake is overcome compared to the disengaged position of the parking brake or the free travel of the parking brake is fully overcome;

determining a parking variable representing a parking process of the motor vehicle with a control unit; and

bringing the parking brake into the intermediate position in response to determining the parking variable.
