Abstract
A device and method for the establishment of quality parameters of a digital map. A currently determined position of the vehicle and a measured value of an attribute of this position is used to calculate a quality parameter which serves as additional information for the data of the digital map. A driver assistance system constitutes an improved aid for a driver of a vehicle, since, in addition to the data of the digital map, the driver assistance system uses the feedback information of the quality parameter.
Claims14
A method for establishing quality parameters for a digital map, the method having the steps:
- detecting a position of a vehicle;
- detecting a current measured value of an attribute of the position;
- extracting a stored value of the attribute of the position of the vehicle from the digital map;
- transmitting the measured value and the extracted stored value as a value pair to an evaluation unit;
- and
- generating, with the evaluation unit, a quality parameter of the attribute of the position on the basis of the value pair;
- and.
- evaluating, by a driver assistance system located in the vehicle, an information item of the digital map by comparing the quality parameter to a quality limiting value;
- wherein the driver assistance system located in the vehicle:
- uses the information item for controlling the vehicle when the comparison indicates that the quality parameter is greater than the quality limiting value, and
- does not use the information item for controlling the vehicle when the comparison indicates that the quality parameter is less than or equal to the quality limiting value.
A driver assistance system located in a vehicle, including:
- a processor located in the vehicle:
- detecting a position of a vehicle,
- detecting a current measured value of an attribute of the position, and
- extracting a stored value of the attribute of the position of the vehicle from the digital map;
- and
- a transmitter transmitting the measured value and the extracted stored value as a value pair to an evaluation unit, the evaluation unit generating a quality parameter of the attribute of the position on the basis of the value pair;
- wherein the processor of the driver assistance system evaluates an information item of the digital map by comparing the quality parameter to a quality limiting value, and the driver assistance system located in the vehicle:
- uses the information item for controlling the vehicle when the comparison indicates that the quality parameter is greater than the quality limiting value, and
- does not use the information item for controlling the vehicle when the comparison indicates that the quality parameter is less than or equal to the quality limiting value
A device for establishing quality parameters of a digital map in a vehicle, wherein the device comprises:
- a position-determining unit configured to detect a position of the vehicle;
- a measuring unit configured to detect a measured value of an attribute of the position;
- a computing unit configured to extract a stored value of the attribute of the position of the vehicle from the digital map;
- and
- a driver assistance system located in the vehicle;
- wherein the measured value and the extracted value serve to calculate a quality parameter;
- wherein the driver assistance system located in the vehicle evaluates and information item of the digital map by comparing the quality parameter to a quality limiting value;
- and
- wherein the driver assistance system located in the vehicle:
- uses the information item for controlling the vehicle when the comparison indicates that the quality parameter is greater than the quality limiting value, and
- does not use the information item for controlling the vehicle when the comparison indicates that the quality parameter is less than or equal to the quality limiting value.
A non-transitory computer-readable medium on which a program element is stored, which program element, when executed on a processor, instructs the processor to carry out the following steps:
- detect a position of a vehicle;
- detect a current measured value of an attribute of the position;
- extract a stored value of the attribute of the position of the vehicle from the digital map;
- transmit the measured value and of the extracted value as a value pair to an evaluation unit;
- and
- generate a quality parameter of the attribute of the position on the basis of the value pair by the evaluation unit;
- evaluate, by a driver assistance system located in the vehicle, an information item of the digital map by comparing the quality parameter to a quality limiting value;
- and
- wherein the driver assistance system located in the vehicle:
- uses the information item for controlling the vehicle when the comparison indicates that the quality parameter is greater than the quality limiting value, and
- does not use the information item for controlling the vehicle when the comparison indicates that the quality parameter is less than or equal to the quality limiting value.
