Abstract
A device is provided for determining a value of a speed limit on a roadway on which a vehicle travels. The device is configured to determine that there is a roadwork situation on the roadway on which the vehicle travels. The device is additionally configured to adjust, in reaction to the determination of a roadwork situation, one or more operating parameters of an algorithm for determining the value of the speed limit.
Claims8
A device for determining a value of a speed limit on a roadway traveled by a vehicle, wherein the device is configured:
- to determine that a roadwork situation is present on the roadway traveled by the vehicle;
- in reaction to the roadwork situation, to adapt an operating parameter of an algorithm for determining the value of the speed limit;
- and at least one of:
- to output information with respect to the value of the speed limit via a user interface of the vehicle to a driver of the vehicle;
- or
- to effectuate at least partially automated longitudinal guidance of the vehicle as a function of the value of the speed limit, wherein:
- the operating parameter is a distance threshold value for a lateral distance of a traffic sign from an edge of the roadway traveled by the vehicle or from the vehicle;
- and
- the device is further configured:
- based on surroundings data from one or more surroundings sensors of the vehicle, to detect the traffic sign at the edge of the roadway and to determine the lateral distance of the traffic sign to the edge of the roadway or to the vehicle;
- and
- to determine the value of the speed limit based on the traffic sign when the lateral distance is less than or equal to the distance threshold value;
- or
- to ignore the traffic sign in determining the value of the speed limit when the lateral distance is greater than the distance threshold value.

A device for determining a value of a speed limit on a roadway traveled by a vehicle, wherein the device is configured:
- to determine that a roadwork situation present on the roadway traveled by the vehicle has ended;
- to determine that since the roadwork situation has ended, it has been impossible to detect any traffic sign relevant for determining the value of the speed limit based on surroundings data from one or more surroundings sensors of the vehicle;
- in reaction to determining that it has been impossible to detect any traffic sign relevant for determining the value of the speed limit based on surroundings data from the one or more surroundings sensors of the vehicle, to determine the value of the speed limit based on map data with respect to a roadway network traveled by the vehicle;
- and at least one of:
- to output information with respect to the value of the speed limit via a user interface of the vehicle to a driver of the vehicle;
- or
- to effectuate at least partially automated longitudinal guidance of the vehicle as a function of the value of the speed limit;
- wherein the map data include limit data with respect to respective speed limits applicable on different roadways of the roadway network;
- and
- wherein the device is further configured to determine that the roadwork situation present on the roadway traveled by the vehicle has ended by:
- determining, based on surroundings data from one or more surroundings sensors of the vehicle, that the roadway traveled by the vehicle was multilane before the roadwork situation;
- determining, based on surroundings data from one or more surroundings sensors of the vehicle, whether the roadway currently traveled by the vehicle includes at least one further lane in addition to a lane currently traveled by the vehicle;
- and
- as a function of whether the roadway currently traveled by the vehicle includes the at least one further lane in addition to the lane currently traveled by the vehicle, determining whether the roadwork situation is ended or not.
