Method and device for operating a pedestrian-protection device of a vehicle, pedestrian-protection device

An apparatus for operating a pedestrian-protection device of a vehicle, comprising:

• a surroundings sensor;
• and
• a contact sensor,
• wherein the apparatus is configured to monitor surroundings of the vehicle to detect a collision object using the surroundings sensor and to determine a type of the detected collision object,
• wherein the apparatus is configured to determine 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,
• wherein the apparatus is further configured to determine a feature of an impact of the detected collision object on the vehicle using the contact sensor and to compare the feature with the at least one predeterminable limit value to make a decision regarding a triggering of at least one pedestrian protection measure of a pedestrian-protection device of the vehicle, and
• wherein the apparatus is further configured to change the predeterminable limit value depending on the determined type of the detected collision object and depending on the determined probability of impact.

A pedestrian-protection device for a vehicle comprising:

• at least one triggerable pedestrian protection measure;
• and
• an apparatus for operating the pedestrian-protection device including a surrounding sensor and a contact sensor,
• wherein the apparatus is configured to monitor surroundings of the vehicle to detect a collision object using the surroundings sensor and to determine a type of the detected collision object,
• wherein the apparatus is configured to determine 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,
• wherein the apparatus is further configured to determine a feature of an impact of the detected collision object on the vehicle using the contact sensor and to compare the feature with the at least one predeterminable limit value in order to make a decision regarding a triggering of at least one pedestrian protection measure of a pedestrian-protection device of the vehicle, and
• wherein the apparatus is further configured to change the predeterminable limit value depending on the determined type of the detected collision object and depending on the determined probability of impact.
