Abstract
A device is proposed for determining a relative speed between a vehicle and a crash object, the device being situated in the vehicle itself. The device has one active surround field sensor system and one contact sensor system. The device ascertains the relative speed with the aid of a first signal, the surround field sensor system and with the aid of a second signal of the contact sensor system.
Claims20
A device for being situated in a vehicle and for determining a relative speed between the vehicle and a crash object, comprising:
- at least one active pre-crash surround field sensor system;
- at least one contact sensor system;
- an arrangement for ascertaining the relative speed based on a first signal of the at least one surround field sensor system and based on a second signal from the at least one contact sensor system, wherein the signal of the contact sensor system is used to correct the relative speed of the pre-crash surround field sensor system.
