Title: METHOD FOR CARRYING OUT DIAGNOSTICS ON A VEHICLE SENSOR SYSTEM, IN PARTICULAR AN AUTONOMOUS VEHICLE, AND VEHICLE SENSOR SYSTEM, IN PARTICULAR AN AUTONOMOUS VEHICLE
Abstract:
In order to be able to carry out self-diagnostics on a vehicle sensor system (FSESA), in particular on an autonomous vehicle in a simple manner and without large additional outlay, it is proposed that in the course of the self-diagnostics of the vehicle sensor system (FSESA) this vehicle sensor system (FSESA) and a further vehicle sensor system (FSESB) observe one another and in the process acquire, in a sensor-system-based fashion (SEA, SEB) in each case at least one extracted system feature (FSESA_SM_FSESB, FSESA_SM`_FSESB, FSESB_SM_FSESA, FSESB_SM`_FSESA) and generate, as a function of sensor-system-related, extrinsic and intrinsic system parameters (SPAe, SPAi, SPBe, SPBi) and the acquired system features "6D-Systempose [FSESA_Th_FSESB], [ FSESA_Th_FSESB] *, [FSESB_Th_FSESA], [FSESB_Th_FSESA] *"-based relative information items (RI1, RI1*, RI2, RI2*) independently of one another by means of homogenous transformation [Th], which relative information items (RI1, RI1*, RI2, RI2*) are preferably formed by the respective vehicle sensor system by means of the entire system parameters/system features or a subset thereof. After this, the vehicle sensor system FSESA compares the self-generated relative information items (RI2, RI2*) of the relative information items (RI2, RI2*) which were generated and transferred by the further vehicle sensor system FSESB. When identity is detected (in the case of identically observed information), the vehicle sensor system (FSESA) operates normally within the scope of the observed system parameters/system features, and otherwise a fault is present.
