Embodiment Construction

[0036] figure 1 A schematic diagram of a vehicle 100 with a device for plausibility checking of a forward-looking sensor system according to an exemplary embodiment of the invention is shown.

[0037] Vehicle 100 has a forward-looking sensor system 110 and two crash sensors 120 . The two crash sensors 120 are arranged at a distance from one another, for example on opposite sides of the vehicle 100 . According to this embodiment, one of the crash sensors 120 is provided on the right front of the vehicle 100 , and the other of the crash sensors 120 is provided on the left front of the vehicle 100 . Crash sensors 120 are designed to each provide an acceleration signal. Forward-looking sensor device 110 can also be referred to as environment sensor 110 . Forward vision sensing device 110 is configured to provide sensor data. Sensor logic 130 is designed to determine collision parameters from the sensor data of forward-looking sensor system 110 and to forward them to evaluation...

Abstract

The invention relates to a method (200) for checking the plausibility of a predictive sensor system (110) of a vehicle (100). The method includes a step of plausibility check (210). The reliability of the collision parameter (214) determined by the sensor signal (212) of the predictive sensor system (110) is checked by using the crash sensor signal (216) of the vehicle (100).

Description

technical field [0001] The invention relates to a method for plausibility checking of a forward-looking sensor system of a vehicle, a corresponding device and a corresponding computer program product. Background technique [0002] A collision of a vehicle can be detected by means of so-called front sensors. In particular, pedestrian protection sensors can be used to detect collisions with pedestrians. A forward-looking sensing device can be used to support collision detection. [0003] Interpretation of data based on environmental sensing devices is generally a very demanding classification task which by itself cannot be 100% solved by the best systems. The data provided by the environmental sensor system can in some cases be flawed due to complex conditions on site, which can lead to serious deviations or so-called “false positives” in the output data. If such data are used to activate, for example, certain airbag stages, the influence should be chosen to be relatively l...
