Method and device for operating a pedestrian-protection device of a vehicle, pedestrian-protection device
First Claim
1. A method for operating a pedestrian-protection device of a vehicle having a surroundings sensor and a contact sensor and configured to trigger at least one pedestrian protection measure, the method comprising:
- monitoring surroundings of the vehicle to detect a collision object using the surroundings sensor;
determining a type of the detected collision object before an impact on the vehicle;
determining a probability of impact of the detected collision object using the surroundings sensor, wherein, in response to the determined probability of impact exceeding a predeterminable threshold value, data of the surroundings sensor is stored and made available for a change of at least one predeterminable limit value;
determining a feature of the impact on the vehicle of the detected collision object after the detected collision object has impacted on the vehicle using the contact sensor;
comparing the feature with the at least one predeterminable limit value in order to make a decision regarding triggering of the at least one pedestrian protection measure; and
changing the at least one predeterminable limit value depending on the determined type of the detected collision object and depending on the determined probability of impact.

Abstract
The disclosure relates to a method for operating a pedestrian-protection device of a vehicle, in particular a motor vehicle, which has a surroundings sensor system and a contact sensor system, and is configured to trigger at least one pedestrian-protection measure. The method comprises monitoring the surroundings of the vehicle to detect a collision object using the surroundings sensor system, and determining the type of detected collision object before an impact with the vehicle. The method further comprises using the contact sensor system to determine an impact feature on the vehicle of the detected collision object, which has impacted with the vehicle, and to compare the impact feature with at least one predefineable limiting value, in order to make a decision about the triggering of the pedestrian-protection measure. In this context there is provision that the limiting value is changed as a function of the determined type of detected collision object.
