Abstract

A vehicle includes an airbag system, a sensor unit, which includes a first sensor module, which permits the sensing of actual driving conditions, and an electronic system, which fires the airbag system in the event of a crash and which is designed to evaluate the sensor signals that are provided by the sensor unit. The electronic system carries out a comparison of sensed actual driving conditions with predetermined critical driving conditions, which indicate a crash. The sensor unit includes a second sensor module, which senses in advance the environmental conditions of the vehicle, which after a certain period of time may lead to critical actual driving conditions. Critical actual driving conditions, whose imminent occurrence has been indicated in advance by the second sensor module, are rated by the electronic system as crash-free driving conditions.
