Control unit and method for driver assistance

1. A control unit configured to provide automated driving assistance for a vehicle, comprising:

a first data interface configured to query sensors for detecting surroundings data of the vehicle;

a second data interface configured to query a steering angle of the vehicle;

an arithmetic unit configured to ascertain driving instructions from the surroundings data of the vehicle transmitted by the sensors;

a third data interface configured to output the driving instructions, the driving instructions including at least one instruction to perform a steering of the vehicle at a standstill;

a fourth data interface configured to selectively activate a braking system of the vehicle such that the vehicle remains braked during the steering performed at a standstill until a predefined steering angle determined by the control unit is reached; and

a fifth interface configured to query motion sensors of the vehicle, wherein the braking system is not activated during the steering performed at a standstill until the query of the motion sensors ascertains a standstill of the wheels of the vehicle.

2. The control unit as recited in claim 1 , further comprising:

a sixth data interface configured to query an input device for releasing the braking system braked during the steering performed at a standstill.

3. The control unit as recited in claim 2 , wherein the third data interface is configured to output a warning when the braking system is released.

4. A parking-assist device for a vehicle, comprising:

surroundings sensors for detecting surroundings data of the vehicle;

an output unit for conveying information to a driver of the vehicle;

a steering angle sensor;

a triggering unit configured to electronically activate a braking system of the vehicle; and

a control unit including:

a first data interface configured to query the surroundings sensors for detecting surroundings data of the vehicle;

a second data interface configured to query the steering angle sensor for a steering angle of the vehicle;

an arithmetic unit configured to ascertain driving instructions from the surroundings data of the vehicle transmitted by the sensors;

a third data interface configured to output the driving instructions, the driving instructions including at least one instruction to perform a steering of the vehicle at a standstill;

a fourth data interface configured to selectively activate the braking system of the vehicle such that the vehicle remains braked during the steering performed at a standstill until a predefined steering angle determined by the control unit is reached; and

a fifth interface configured to query motion sensors of the vehicle, wherein the braking system is not activated during the steering performed at a standstill until the query of the motion sensors ascertains a standstill of the wheels of the vehicle.

5. A method for automated driving assistance for a vehicle, comprising:

detecting a current steering angle;

outputting driving instructions to a driver of the vehicle, the driving instructions including at least one steering instruction for steering at a standstill of the vehicle;

activating a braking system such that the braking system is braked during the steering performed at a standstill; and

not releasing the braking system until a predefined steering angle has been reached during the steering performed at a standstill;

wherein motion sensors of the vehicle are queried prior to activating the braking system during the steering performed at a standstill, and wherein the activating of the braking system takes place only if the vehicle is determined to be at a standstill.

6. The method as recited in claim 5 , wherein a parking brake of the vehicle is activated during the steering performed at a standstill.

7. The method as recited in claim 6 , wherein a warning is output when the braking system is released.
