Problems solved by technology

But triggering is often implemented too late to always be effective in protecting pedestrians
Especially when pedestrians enter the road directly in front of motor vehicles, for example through a gap in a parking space, it is often not possible to effectively protect pedestrians

Embodiment Construction

[0051] figure 1 A device 2 is shown for triggering an exterior protection function 4 for a motor vehicle 1 to protect external road users particularly deserving of protection, in particular pedestrians. The device 2 has a controller unit 3 for evaluating sensor data of a first sensor device 5 for sensing a collision object and for outputting a first trigger signal for at least one external protective function 4 ; and an auxiliary control A controller unit 12 is provided for evaluating sensor data of a second sensor device 6 for sensing a collision object and for directly outputting a second trigger signal for at least one exterior protective function 4 . When a collision object has been detected, the first trigger signal or the second trigger signal is triggered. The auxiliary controller unit 12 is arranged such that the controller unit 3 is bypassed when outputting the second trigger signal.

[0052] The first sensor device 5 includes both the surroundings sensor 8 and the ...

Abstract

A device (2) for activating at least one exterior protection function (4) for a motor vehicle (1) to protect external road users particularly deserving of protection, especially pedestrians, said device having: a control A controller unit (3) for evaluating sensor data of a first sensor device (5) for sensing a collision object and for outputting a second sensor device for the at least one external protective function (4) a trigger signal; and an auxiliary controller unit (12) for analyzing sensor data of a second sensor device (6) for sensing a collision object and for when a collision object has been identified A second triggering signal for the at least one external protective function (4) is output directly, wherein the auxiliary controller unit (12) is arranged such that the control is bypassed when outputting the second triggering signal unit (3).

Description

technical field [0001] The invention relates to a device and a method for triggering at least one exterior protection function for a motor vehicle for the protection of external road users, in particular deserving protection, in particular pedestrians. Background technique [0002] Modern motor vehicles usually have sensors by which collisions with objects in the surroundings of the motor vehicle can be detected before and / or after a collision. Measures for protecting pedestrians in the event of a collision are also known. Such measures are usually activated as soon as a collision has been detected by the sensors. However, the triggering often takes place too late, so that the pedestrian cannot always be effectively protected. Especially when pedestrians enter the road directly in front of the motor vehicle, for example through a parking space gap, it is often not possible to effectively protect pedestrians. Contents of the invention [0003] Here, a particularly advant...
