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.
