Data system, data transmission system and method for data transmission for a towing vehicle and/or trailer vehicle

Abstract

Data system of a towing vehicle and / or trailer vehicle, in particular for commercial vehicles such as a heavy goods vehicle or heavy goods vehicle trailer or a passenger bus or passenger bus trailer,having: a control device, a sensor system for picking up and processing sensor data, a BUS system for transmitting the sensor data between the control device and the sensor system, an interface of theBUS system for transmitting the sensor data to an interface of a BUS system of a respective other data system of the towing vehicle and / or trailer vehicle within the framework of a data transmissionsystem, wherein the BUS system has a first BUS device in the form of a CAN BUS, characterized in that the BUS system has a second BUS device in the form of an ETHERNET BUS, and the data system of thetowing vehicle and / or trailer vehicle in each case also has an intelligent switch, coupled to the control device and / or to the interface, that is designed to couple the towing vehicle and the trailervehicle by means of the ETHERNET BUS in a manner coordinated based on need by activating the second BUS device in the form of an ETHERNET BUS.

Description

technical field [0001] The invention relates to a data system and a tractor vehicle and / or a trailer vehicle respectively having a data system for a tractor vehicle and / or a trailer vehicle, in particular for a commercial vehicle such as a truck or a truck trailer or a passenger car or a passenger car trailer Data transmission system for the data system of the trailer vehicle. To this end, the invention relates to a data system according to the preamble of claim 1 , a data transmission system according to the preamble of claim 11 , and a tractor and / or trailer vehicle according to claim 21 . The invention also relates to a corresponding method for data transmission for a tractor vehicle and / or a trailer vehicle according to the preamble of claim 14 . Background technique [0002] Such data systems as described above typically include: [0003] - control device, [0004] - sensor systems for receiving and processing sensor data, [0005] - a bus system for transferring se...

Problems solved by technology

[0033] Alternatives to CAN bus-based data systems developed so far, such as power-based communication (English: Powerline Communication, PLC) according to SAE J24997 etc. and real-time transmission of data, such as camera data, lidar or radar data, or ancillary solutions via additional cables, plugs or similar connections, are reluctantly accepted by customers because this Increased system complexity and cost to deal with

[0034] Data transmission systems with higher transmission rates, such as broadcasting solutions, these broadcasting solutions can be, for example, radio-based broadcasting solutions or point-to-point (English: Pear to Pear)-based solutions, such as vehicle-to-vehicle (English : Car to Car) or car-to-something (English: Car to X) communication as an alternative relies on additional prerequisites that are not widely available or are limited by limited reliability and transmission reliability

Therefore, there are usually costs associated with "pairing" this system, and moreover "pairing" connections are data-technically insecure and also susceptible to interference or modification
