Abstract
An assessment module for assessing data from a digital map for a vehicle. The assessment is made on the basis of a piece of dedicated map quality information and measurement data from an ambient sensor system in the vehicle. The connected driver assistance systems and safety systems in the vehicle use the digital map data on the basis of the assessment.
Claims14
A vehicle system for assessing data from a digital map, and controlling a vehicle, said vehicle system comprising:
- a computation unit including a processor located in the vehicle configured to accept data from the digital map and to perform an assessment of the data by computing a quality of the data based on a plurality of pieces of dedicated map quality information and validating the data based on measurement data from an ambient sensor system in the vehicle;
- a driver assistance system located in the vehicle, the driver assistance system coupled to the processor of the computation unit via a data bus and configured to control the vehicle;
- and
- an interface located in the vehicle for transferring, via the data bus, the assessment to the driver assistance system which uses at least a portion of both the data from the digital map and the data from the ambient sensor system to control the vehicle:
- based more on the data from the digital map than the data from the ambient sensor system when the transferred assessment via the data bus indicates that the computed quality is greater than or equal to a threshold, and
- based more on the data from the ambient sensor system than the data from the digital map when the transferred assessment via the data bus indicates that the computed quality is less than the threshold.
A method for assessing data from a digital map for a vehicle system of a vehicle, and controlling the vehicle, said method comprising the following steps:
- accepting, by a processor located in the vehicle system, data from the digital map;
- assessing, by the processor located in the vehicle system, the data by computing a quality of the data based on a plurality of pieces of dedicated map quality information and validating the data based on measurement data from an ambient sensor system located in the vehicle;
- controlling, by a driver assistance system located in the vehicle and coupled to the processor via a data bus located in the vehicle, the vehicle;
- and
- transferring, by the processor located in the vehicle system, via the data bus located in the vehicle, the assessment to the driver assistance system which uses at least a portion of both the data from the digital map and data from the ambient sensor system to control the vehicle:
- based more on the data from the digital map than the data from the ambient sensor when the transferred assessment via the data bus indicates that the computed quality is greater than or equal to a threshold, and
- based more on the data from the ambient sensor system than the data from the digital map when the transferred assessment via the data bus indicates that the computed quality is less than the threshold.
A non-transitory computer-readable medium which stores a program element which, when executed on a processor located in a vehicle system of a vehicle, instructs the processor to control the vehicle by performing the following steps:
- accept, by the processor located in the vehicle system, data from a digital map;
- perform, by the processor located in the vehicle system, an assessment of the data by computing a quality of the data based on a plurality of pieces of dedicated map quality information and validating the data based on measurement data from the ambient sensor system located in the vehicle;
- controlling, by a driver assistance system located in the vehicle and coupled to the processor via a data bus located in the vehicle, the vehicle;
- and
- transfer, by the processor located in the vehicle system, via the data bus located in the vehicle, the assessment to the driver assistance system which uses at least a portion of both the data from the digital map and the data from the ambient sensor system to control the vehicle:
- based more on the data from the digital map than the data from the ambient sensor system when the transferred assessment via the data bus indicates that the computed quality is greater than or equal to a threshold, and
- based more on the data from the ambient sensor system than the data from the digital map when the transferred assessment via the data bus indicates that the computed quality is less than the threshold.
