Abstract: A method for generating a signal representing an occupation of a vehicle seat of a vehicle including the steps: detecting a signal of a sensor system for detecting a dynamic parameter with respect to the vehicle seat; evaluating the signal, in particular, a progression of the signal; generating a seat occupancy signal as a function of the evaluation of the signal, the seat occupancy signal being suited for indicating whether the vehicle seat is occupied by a person or by an object.

Abstract: A device for a vehicle, particularly a motor vehicle, includes an environment sensor system which has at least one environment sensor for contactlessly detecting at least one environment region, means for adjusting the environment region to be detected, and a device for determining the environment region to be detected. The device has a position sensor which detects the tilting of the vehicle in respect of a vehicle base, and the means adjust the environment region to be detected depending on the tilt of the vehicle.

Abstract: A communication method is provided for transmitting useful data between a first traffic participant, at least one second traffic participant, and a central communication device. It is provided that the first traffic participant provides a data packet and transmits it to the central communication device, the data packet being assigned to a changing key that is transmitted together with the data packet, and that the first traffic participant transmits an identifier together with the key to the second traffic participant, and that the second traffic participant requests from the central communication device, using the key, the data packet assigned thereto, and assigns it to the first traffic participant. Also provided is a communication system.
