Abstract
A control unit for a vehicle is designed to detect movement sensor data with regard to a movement of at least one component of the vehicle. The movement is or has been effected by a roadway driven upon by the vehicle. In addition, the control unit is designed to detect a lane boundary of the roadway on the basis of movement sensor data and, in reaction thereto, to cause a functional reaction of the vehicle.
Claims10
An apparatus for a vehicle, comprising:
- a control unit operatively configured to:
- record motion sensor data in relation to a movement of at least one component of the vehicle, wherein the movement is or was brought about by a roadway being traveled by the vehicle;
- recognize a traffic lane boundary of the roadway on the basis of the motion sensor data;
- and
- bring about a functional response of the vehicle in response thereto, wherein
- the traffic lane boundary has a height profile perpendicular to a surface of the roadway being traveled by the vehicle that differs from a basic profile of the roadway;
- the motion sensor data display a temporal profile of a measured variable of the movement of the at least one component of the vehicle;
- the control unit is further operatively configured to determine the height profile of the traffic lane boundary based on the temporal profile of the measured variable of the movement of the at least one component of the vehicle;
- the traffic lane boundary is recognized based on the height profile of the traffic lane boundary;
- the control unit is further operatively configured to determine a type of the traffic lane boundary from a plurality of different types of traffic lane boundaries by comparing the temporal profile of the measured variable of the movement of the at least one component of the vehicle with at least one reference profile;
- and
- the plurality of different types of traffic lane boundaries comprises at least two of:
- a traffic lane marking, a shoulder next to the roadway being traveled by the vehicle, a border line, a guideline and cat's eyes arranged on the roadway.

A method for providing a driving function in a vehicle, wherein the method comprises:
- recording motion sensor data in relation to a movement of at least one component of the vehicle, wherein the movement is or was brought about by a roadway being traveled by the vehicle;
- recognizing a traffic lane boundary of the roadway on the basis of the motion sensor data;
- and
- bringing about a functional response of the vehicle in response thereto, wherein
- the traffic lane boundary has a height profile perpendicular to a surface of the roadway being traveled by the vehicle that differs from a basic profile of the roadway;
- the motion sensor data display a temporal profile of a measured variable of the movement of the at least one component of the vehicle;
- the method further comprises determining the height profile of the traffic lane boundary based on the temporal profile of the measured variable of the movement of the at least one component of the vehicle;
- the traffic lane boundary is recognized based on the height profile of the traffic lane boundary;
- the method further comprises determining a type of the traffic lane boundary from a plurality of different types of traffic lane boundaries by comparing the temporal profile of the measured variable of the movement of the at least one component of the vehicle with at least one reference profile;
- and
- the plurality of different types of traffic lane boundaries comprises at least two of:
- a traffic lane marking, a shoulder next to the roadway being traveled by the vehicle, a border line, a guideline and cat's eyes arranged on the roadway.
