System for protection of a vulnerable road user and method for operating the system
First Claim
1. A method for operating a system of a vehicle for protection of a vulnerable road user, said system comprising a remote sensor, a contact-based sensor and a pedestrian protection means, the method comprising:
- scanning a region in front of said vehicle by said remote sensor in order to detect a target object;
if a target object is detected, classifying said target object into an object category based on information from said remote sensor;
selecting a selectable fire interval of an evaluation algorithm using said object category as input;
if an impact is detected by said contact-based sensor, said contact-based sensor sending information about the impact as a signal to said evaluation algorithm;
said evaluation algorithm evaluating if said signal is within said selectable fire interval, and in that case activating said pedestrian protection means;
wherein a plurality of n different object categories is used corresponding to n fire intervals of said evaluation algorithm, n being between 2 and 20.

Abstract
A method is provided for operating a system of a vehicle for protection of a vulnerable road user. The system includes a remote sensor, a contact-based sensor, and a pedestrian protection device. The method may include scanning a region in front of the vehicle by the remote sensor to detect a target object and, if a target object is detected, classifying the target object into an object category based on information from the remote sensor. The method may also include selecting the selectable fire interval of an evaluation algorithm using the object category as input and, if an impact is detected by the contact-based sensor, the contact-based sensor sending information about the impact to the evaluation algorithm. The method may also include the evaluation algorithm evaluating if the signal is within the selectable fire interval, and in that case activating the pedestrian protection device.
