Abstract
A method for transmitting information between a motor vehicle and a vehicle-external server. A contour profile of a road to be traveled along by the vehicle, which is stored on the server, is retrieved by the vehicle via a vehicle-server interface. The contour values of the road contour profile lying ahead of the vehicle are cyclically transmitted by the server to the vehicle at a definable interval. A contour value is transmitted per cycle, which lies ahead of the vehicle at a speed-dependent interval. In addition, a chassis system for carrying out the method and a vehicle are provided with the chassis.

A method for transmitting information between a motor vehicle and a vehicle-external server, wherein a contour profile for a road to be traveled along by the vehicle, which is stored on the server, is retrieved by the vehicle via a vehicle-server interface, wherein contour values of the contour profile lying ahead of the vehicle are transmitted by the server to the vehicle cyclically, at a definable time interval, wherein one contour value is transmitted per cycle, which lies at a speed-dependent distance ahead of the vehicle.
A chassis system of a vehicle provided with a control unit, which is configured to request at a definable interval via a vehicle-server interface from a vehicle-external server to send contour values of a contour profile of a road to be traveled along by the vehicle, wherein the contour values of the contour profile lying ahead of the vehicle are transmitted cyclically, at a timely definable interval, wherein one contour value is transmitted per cycle.
