Abstract
A device for activating an actuator system for protecting a pedestrian is provided, the device being connected to an environment sensor system and a contact sensor system. The device compares a first signal from the contact sensor system to a threshold. The threshold or the first signal is changed as a function of a second signal of the environment sensor system and the actuator system is activated as a function of the comparison.
Claims22
A device for activating an actuator system for protecting a pedestrian, the device being connected to an environment sensor system and a contact sensor system, the device, comprising:
- an arrangement for performing a first comparison of a first signal from the contact sensor system to a threshold;
- an arrangement for comparing the first signal to a noise threshold to ascertain a staffing point for the first comparison;
- an arrangement for changing one of the threshold and the first signal as a function of a second signal of the environment sensor system, the actuator system being activated as a function of the comparing;
- and
- an arrangement for changing the threshold in response to passage of a predetermined amount of time.
