Abstract
A control unit for a driving assistance of a vehicle includes a data interface for querying sensors for detecting surroundings data of the vehicle, a data interface for querying a steering angle of the vehicle, an arithmetic unit for ascertaining driving instructions based on the surroundings data of the vehicle transmitted by the sensors, a data interface for outputting the driving instructions, the driving instructions including at least one instruction to perform a steering of the vehicle at a standstill, and an interface for activating a braking system of the vehicle in such a way that the vehicle is braked during the steering performed at a standstill until a predefined steering angle is reached.
Claims7
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.
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.
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.
