Embodiment Construction

[0032] In the following, an automated motor vehicle is also understood synonymously to mean a partially automated motor vehicle, an autonomous motor vehicle and a partially autonomous motor vehicle.

[0033] In particular, the invention includes the idea of ​​optimizing a digital map for an automated vehicle, wherein in particular the electronic storage requirements for the mentioned digital map should be kept as low as possible.

[0034] To this end, it is proposed to first evaluate the limited area of ​​a digital map (HAD map, English: highly automated driving) as follows: whether and how an improved coverage of landmarks and thus an improved positional accuracy of positioning can be achieved. For this purpose, the characteristics (e.g. number, location, type, visibility, age, etc.) of landmarks already present in the area are used in order to evaluate how the removal or addition of landmarks would affect the electronic storage requirements for the digital map degree of bene...

Abstract

A method for optimizing a digital map for an automated vehicle includes selecting an area of the digital map, ascertaining a localization quality provided with the aid of the digital map in the selected area based on usage data of the digital map, and providing at least one suggestion for optimizing landmarks of the digital map with respect to an electronic memory requirement of the digital map. The invention relates to a corresponding device and a computer program.

Description

technical field [0001] The invention relates to a method for optimizing a digital map for an automated vehicle. The invention also relates to a device for optimizing a digital map for an automated vehicle. The invention also relates to a computer program. Background technique [0002] Methods and systems are known for mapping a traveled road by means of sensors installed in a vehicle (for example cameras, radar sensors, ultrasonic sensors, etc.). In addition to the mentioned sensors, these systems usually also have a radio interface (for example via a connection unit (English: connectivity unit)) for transmitting the measured sensor data to a server. In this way, fleets can map their surroundings with the aid of vehicle sensors by transmitting their sensor data, for example, to a server. This transfer of so-called "fleet-mapping data" is known. [0003] The sensor data is collected on a server and a digital map for the relevant road section is generated from the data of ...
