Abstract: A method and a device, respectively, for controlling a barricade of a parking space for a vehicle are proposed, the method being used to change a code as needed with which authorization for controlling the barricade of the parking space is attained and to recognize a plurality of codes as authorized for one barricade. A code is able to be changed using a password. The radio signals are preferably transmitted via Bluetooth. A dwell time of the vehicle in the parking space may also be logged. A code may be designed as a personal identification number or as an identification number of the vehicle or of the radio module. The barricade is designed as either a garage door or a barrier.

Abstract: A method for transmitting data packets between motor vehicles includes transmitting individual data packets including vehicle data and generation data for the individual data packets. Other motor vehicles may combine the individual data packets into combined data packets and transmit them. The data packets may include fields, each of which may include data-packet generation data and vehicle data. To allow processing to be performed in the transmitting/receiving stations in motor vehicles. Permanently installed radio stations allow a main station to supply information columns at clearly defined points with traffic information to inform users outside of the roads.
