Sensor product, simulator and method for simulating sensor measurements, merging sensor measurements, validating a sensor model and designing a driver assistance system

摘要

In addition to a sensor (1), a sensor model (10) is provided, which describes and / or virtually models hardware and / or physical properties of the sensor (1) in such a way that a simulator is able to carry out virtual measurements (30) to simulate the sensor (1) in an environmental model (20). The sensor model (10) is modularly separated from the environmental model (20) and is independent. For each type of sensor model (10) to be used, the corresponding physical properties of the environment are taken into account in the environment model (20). For a video camera, for example, these are the geometry and the textures of the objects. The division between the sensor model (10) and the environmental model (20) has so far not been common, but it means that the special knowledge of the developers of the sensor hardware and the knowledge of the application domain are not combined in one person or in a team must be recorded and used or reused independently of each other. Furthermore, it is possible to use one sensor (1) for a number of driver assistance applications, since the strict coupling between sensor (1) and driver assistance application is broken up by the modularly reusable sensor model (10). As a result, redundancy in the overall driver assistance system is better exploited.
