Definitions
- the invention relates to the field of vehicles and in particular to the field of commercial vehicles.
- Such commercial vehicles include towing vehicles, such as trucks or semi-trailers, and trailer vehicles, such as drawbar trailers or semi-trailers.
- the invention relates to trailer vehicles.
- the vehicles considered here have a large number of control devices, which are also called “electronic control units” or ECUs for short.
- the control devices are used to control individual functions of the vehicle.
- actuators of the vehicle are controlled or sensors of the vehicle are read out by the control devices.
- vehicle control devices are brake control devices, EBS or TEBS for short, for controlling various types of brake functionalities, such as controlling the vehicle's friction brakes, and air spring control devices for controlling air suspension.
- Control devices in modern vehicles are connected to one another via a vehicle network for data communication, in particular a data bus, in order to exchange data with one another.
- a control unit of an air suspension system can be used to determine the mass of the vehicle.
- a sensor measures the prevailing pressure in the air bellows and transmits this to the control unit of the air suspension system.
- the control unit can determine the mass from the prevailing pressure and provide the specific mass, for example, to a brake control unit, whereby the brake control unit can then take these masses into account when controlling the actuators.
- control devices Due to the increasing number of such control devices and thus increasing interaction between the control devices, the demands on the vehicle network for data exchange are increasing, especially with regard to the data security of a vehicle network system that includes the control devices and the Vehicle network itself includes.
- the requirements for data security are becoming particularly relevant due to increasingly automated driving functions, which enable the vehicle to operate partially or completely autonomously and are also implemented using the control devices mentioned.
- Control devices for implementing automated driving functions must be able to access the vehicle's sensors and actuators without errors, whereas manipulation of such access can lead to dangerous driving situations or accidents.
- control devices that can perform safety-critical functions are often not connected to the vehicle's general data buses. Rather, secured connections are provided for such control devices, so that such control devices exchange control commands, in particular safety-critical control commands, with the secured connections.
- a trailer network system is constructed in such a way that a safety-critical control device, such as the brake control device, receives safety-critical commands, for example for activating the friction brakes, from the towing vehicle via a standardized interface with a protocol according to ISO 11992-2.
- a safety-critical control device such as the brake control device
- Modern trailer vehicles also have an additional interface that exchanges data with the towing vehicle using a protocol according to ISO 11992-3.
- the additional interface can be used to communicate with other components of the trailer vehicle, which are connected, for example, via a bus system.
- the object of the present invention is therefore to address the problems of the prior art.
- the aim is to reduce the risk that attacks by vehicle components on safety-critical systems lead to dangerous driving interventions.
- an alternative to what is known from the prior art should be found.
- the invention describes a trailer network system for data communication in a trailer vehicle according to claim 1.
- the trailer network system is used for data communication in a trailer vehicle.
- the trailer network system includes at least two main control devices.
- the main control units are each set up to carry out safety-relevant functions of the trailer vehicle.
- the trailer network system also includes at least one auxiliary control device.
- the secondary control unit is used to execute safety-irrelevant functions, i.e. functions that are not safety-relevant.
- the trailer network system also includes a main data bus.
- the main data bus includes several main data bus interfaces.
- the main control devices are each connected to a main data bus interface of the several main data bus interfaces.
- the main control devices are connected to each other via the main data bus to exchange data.
- the secondary control unit is not connected to the main data bus, i.e. not connected. In the case of several secondary control devices, all secondary control devices are not connected to the main data bus.
- the trailer network system also includes a secondary data bus with multiple secondary data bus interfaces.
- a secondary data bus interface of the plurality of secondary data bus interfaces is connected to one of the main control devices.
- Another secondary data bus interface is connected to another of the main control devices.
- Another secondary data bus interface of the several The secondary data bus interface is connected to the secondary control unit.
- all main and secondary control devices are each connected to the secondary bus.
- the secondary data bus is therefore used to exchange data between all main and secondary control devices in the trailer network system.
- the main control device or devices are connected to one another by two data buses, namely the main data bus and the secondary data bus.
- the idea of the invention is that the main data bus only connects the main control devices but not the secondary control devices.
- the main data bus therefore does not provide any interfaces for connecting secondary control devices on the trailer vehicle.
- An additional data bus is provided for connecting additional control devices. Control devices that perform functions that are not relevant to safety and can pose a danger to control devices that perform functions that are relevant to safety can therefore only be connected via the secondary data bus.
- main control devices Secure communication between main control devices is therefore possible via the main data bus, so that safety-critical commands, which are received, for example, by one of the main control devices from a towing vehicle or another main control device, can be safely transmitted to the main control device.
- the trailer's secondary control units cannot access the main data bus because it is not accessible to the secondary control units.
- This structure of the trailer network system enables secure communication between the control devices that carry out safety-relevant functions.
- the structure enables the main control devices to also communicate via the secondary data bus in the event of a failure of the main data bus. There is therefore a partially redundant bus connection, so that the disadvantage of the additional effort to increase data security is outweighed by a simultaneous increase in reliability.
- the main control devices each correspond to a control device that is set up to influence a driving function of the trailer vehicle.
- each of the main control devices is set up to control an actuator of the trailer vehicle.
- the secondary control device is a control device that is set up to leave the driving function of the trailer vehicle unaffected.
- the secondary control device is set up to carry out an actuator-free function.
- the main control devices are therefore used to control all functions that affect the movement of the trailer and have a direct influence on the journey or locomotion.
- the secondary control unit therefore corresponds to a control unit that has no direct influence on the travel or movement of the trailer vehicle.
- Secondary control units which therefore have no direct influence on the driving function, remain unconnected to the main data bus and therefore cannot have any influence on main control units, which exchange safety-relevant data via the main data bus and, in particular, can influence the driving functions of the trailer vehicle through this exchange of data.
- each of the main control devices is set up to have at least one actuator for actuating a service brake, an actuator for actuating a parking brake, an actuator for raising and / or lowering a lifting axle, an actuator for raising and / or lowering a trailer support foot, one Actuator for controlling a trailer vehicle level control or an actuator, in particular an electric motor, for driving or braking a wheel or an axle of the trailer vehicle.
- the secondary control device is set up to carry out a function that differs from the control of the actuators mentioned according to this embodiment, which can be controlled by the main control device.
- a final list of actuators is therefore specified, each of which can be controlled via several main control units.
- a first main control unit is used as a control unit for controlling a service brake and another main control unit is used as a control unit for raising and/or lowering a Lift axle.
- another main control unit is designed as a control unit for driving or braking a wheel or an axle.
- secondary control units are set up to carry out a function that differs from the complete list of actuators.
- the actuators mentioned are clearly actuators whose actuation represents a safety-relevant function and is therefore carried out by a main control unit. Such actuators are not controlled by secondary control devices, but only by main control devices. Safety-critical commands to a master controller that are sent on the slave bus from a slave controller that is not connected to the master data bus can be ignored. Data security in the communication of all control devices that have an influence on these safety-relevant actuators can be guaranteed against attacks from control devices that are not connected to the main data bus.
- At least one of or all of the main control devices comprises a data interface unit.
- the data interface unit is connected to a main data bus interface and a secondary data bus interface.
- the data interface unit is set up to distinguish between disturbed and undisturbed data traffic on the main data bus, i.e. to recognize whether the data traffic is disturbed or undisturbed. If the data interface unit detects undisturbed data traffic on the main data bus, the data interface unit is set up to ignore safety-critical data on the secondary data bus.
- Safety-critical data is preferably predefined data or data packets, which include, for example, a command to activate the brakes of the trailer vehicle.
- the data interface unit is preferably also set up not to ignore, i.e. to process, safety-critical data on the secondary data bus in the event that disrupted data traffic on the main data bus is detected.
- the main control device is therefore designed by the data interface unit to receive safety-critical data, such as data that is sent by a secondary control device connected to the secondary data bus and the Corresponding to safety-critical data should be ignored as long as operation with the main data bus, namely undisturbed data traffic with another main control unit, is possible.
- An attack on the main control device by a secondary control device that is connected to the secondary data bus is therefore completely prevented if the main data bus is undisturbed.
- non-critical data can also be sent from secondary control devices to the brake control device via the secondary data bus and processed by the brake control device.
- the trailer network system includes one or more secondary control devices, which are designed as a telematics system, wireless interface module, operating device or display device.
- the trailer network system therefore includes one or more of a telematics system, a wireless interface module, an operating device and a display device.
- a secondary control device is connected as a display device to the secondary data bus via a secondary data bus interface
- other secondary control devices can preferably display parameters with the display device.
- Such parameters can also include parameters that are provided by a main control device on the secondary data bus.
- the secondary control devices can therefore communicate with each other and with the towing vehicle, for example via a main control device designed as a trailer interface module.
- Processing of data from a main control device designed as a trailer brake control device by the secondary control devices is also possible, although safety-critical data from one of the secondary control devices addressed to the trailer brake control device, in particular by the data interface unit, are not processed in the trailer brake control device.
- the trailer network system comprises a plurality of main control devices, one of the main control devices corresponding to a trailer brake control device and being set up to activate friction brakes of the trailer vehicle.
- Another main control unit corresponds to a control unit for controlling an electric drive of the trailer vehicle.
- Safety-critical data therefore includes braking requests for activation of the friction brakes, which are addressed to the trailer brake control unit, for example, by a main control unit designed as a trailer interface module.
- Further safety-critical data are acceleration requirements for activating an electric drive controlled by the brake control unit or braking requirements for activating recuperation operation of the electric drive. Accordingly, braking requests can be transmitted to the trailer brake control unit through the main data bus in order to activate the friction brakes. However, braking requests via the secondary data bus are preferably ignored as long as the trailer brake control unit detects undisturbed data traffic on the main data bus.
- the trailer network system comprises a plurality of main control devices, with a trailer brake control device being formed by at least two of the main control devices. At least one of, several of or all of the main control devices forming the trailer brake control device are set up to control friction brakes of the trailer vehicle.
- Safety-critical data includes braking requests for activation of the friction brakes, which are addressed to at least one of the main control units forming the trailer brake control unit. Safe control of a trailer brake control unit formed by several main control units is therefore possible.
- the trailer network system comprises a plurality of main control devices, one of the main control devices being designed as a trailer interface module and having a first towing vehicle data interface in order to exchange data with a towing vehicle.
- the first towing vehicle data interface is an Ethernet data interface and particularly preferably a Gigabit Ethernet data interface. Fast data exchange between the towing vehicle and the trailer vehicle is possible via such Ethernet connections that can be provided with the first towing vehicle data interface, for example in order to exchange large amounts of data from cameras directly connected either to the secondary data bus or to the trailer interface module in addition to safety-critical data for safety-critical systems, such as braking requirements.
- the main control unit designed as a trailer interface module comprises a second towing vehicle data interface.
- the second towing vehicle data interface is also used to exchange data with the towing vehicle.
- the second towing vehicle data interface is a standardized data interface according to ISO 11992-3.
- the trailer network system comprises a main control unit designed as a brake control unit with a third towing vehicle data interface.
- the third towing vehicle data interface is set up to exchange data with the towing vehicle.
- the third towing vehicle data interface is a standardized interface designed in accordance with the ISO 11992-2 standard. This means that the trailer network system will also be compatible in the future with towing vehicles that do not have an Ethernet data interface but at least have an ISO 11992-2 interface to control the brakes of the trailer vehicle.
- the invention also includes a trailer vehicle with a trailer network system according to one of the aforementioned embodiments. Furthermore, the invention includes a combination with a trailer vehicle according to the invention and a towing vehicle.
- the invention includes a method for operating a trailer network system according to one of the embodiments, a trailer vehicle according to the invention or a trailer according to the invention.
- At least one or each of the main control devices recognizes self-addressed data packets with safety-critical data on the secondary data bus.
- the main control unit determines whether the main data bus is disturbed or not.
- the recognized data packet is processed, if the main data bus is disturbed and discarded if the main data bus is undisturbed.
- an error message is issued by the main control unit if safety-critical data is received on the secondary data bus while the main data bus is simultaneously undisturbed.
- Secondary control devices connected to the secondary data bus which send safety-critical data to a main control device, therefore remain uncritical for the operation of the trailer vehicle as long as the main data bus is undisturbed.
- the probability of an attack on the brake control unit by a secondary control unit is thus reduced and limited to the case that the main data bus is disrupted.
- the probability of an attack on a main control unit by a secondary control unit is therefore significantly reduced.
- the purpose of issuing an error message is to make an attack visible. Actions can be taken by an operator to counter further attacks.
- the main control device or each of the main control devices recognizes data packets with non-safety-critical data on the secondary data bus.
- a data packet with non-safety-critical data recognized in this way is processed by the main control unit.
- Such non-safety-critical data includes, for example, the retrieval of certain parameters from the brake control unit, for example an operating state, by a secondary control unit for display, transmission or further processing.
- the method includes receiving safety-critical data for a main control device designed as a trailer brake control device from the towing vehicle via the first towing vehicle data interface or the second towing vehicle data interface.
- a main control unit designed as a trailer interface module which is used for this purpose, also determines or detects whether the main data bus is disturbed or not, i.e. whether data traffic is disturbed or whether data traffic is undisturbed is possible.
- a data packet addressed to the trailer brake control unit with the received safety-critical data is sent out on the main data bus with the trailer interface module if the Main data bus is undisturbed. If the main data bus is disrupted, the data packet is sent to the trailer brake control unit on the secondary data bus.
- the method includes receiving data for an auxiliary control device from the towing vehicle via the first towing vehicle data interface or the second towing vehicle data interface through the trailer interface module.
- the method according to this embodiment includes sending a data packet addressed to the secondary control device with the data on the secondary data bus, regardless of whether the main data bus is disturbed or not. Accordingly, data intended for the secondary control devices is always sent on the secondary data bus.

- Trailer vehicle 12 and towing vehicle 14 form a team 15.
- the towing vehicle 14 has a towing vehicle brake control device 16, which, for example, generates a braking request 17 for friction brakes of the towing vehicle 14 depending on a driver's request.
- a braking request 17 for a trailer vehicle 12 is also generated in the towing vehicle brake control unit 16.
- Braking requests 17 for the trailer vehicle 12 are transmitted as data to the trailer vehicle 12, such data being predefined as safety-critical data 18.
- the towing vehicle brake control unit 16 In order to send the safety-critical data 18 of a braking request 17 to the trailer vehicle 12, the towing vehicle brake control unit 16 generates the Braking request 17 and transmits this to a towing vehicle interface module 20.
- the towing vehicle interface module 20 generates a data packet 21 with the safety-critical data 18 and transmits this to the trailer network system 10 via a first data connection 22.
- the trailer network system 10 includes a trailer interface module designed as a main control unit 23 24, which is connected to the first data connection 22 via a first towing vehicle data interface 26.
- the first data connection 22 is preferably an Ethernet data connection 28 and in this case a Gigabit Ethernet data connection 30.
- the first towing vehicle data interface 26 is an Ethernet data interface 32 and in this case a Gigabit Ethernet data interface 34.
- the safety-critical data 18 are transmitted from the trailer interface module 24 via a main data bus 36 to a further main control unit 23, which is designed as a trailer brake control unit 38 of the trailer network system 10.
- the trailer interface module 24 corresponds to a gateway module. This serves the purpose of mediating connections between different network sections. Different communication protocols can be used in the network sections.
- the gateway module is designed to carry out protocol conversion so that messages in the format of one communication protocol are converted into messages of the other communication protocol and vice versa.
- the gateway module can be housed in a separate housing in the manner of an electronic control device or, alternatively, it can also be part of a main control device 23.

- the other main control devices 23 are each set up to have an actuator 79 for actuating a parking brake 81, an actuator 82 for raising and / or lowering a lifting axle 83, an actuator 84 for raising and / or lowering a trailer support foot 85, an actuator 86 for controlling a trailer vehicle level control 87 and an actuator 88 , namely an electric drive 70, for driving or braking a wheel 89.
- Each of the mentioned actuators 77, 79, 82, 84, 86, 88 serves to execute one of several safety-relevant functions 41 that influence driving functions 43 of the trailer vehicle 12.
- the main data bus 36 differs from the secondary data bus 42 in that the main data bus 36 comprises main data bus interfaces 44, 48, each of which is connected to one of the main control devices 23, the secondary data bus 42 being in addition to the already mentioned secondary data bus interfaces 46, 50, which are connected to the main control device 23 designed trailer interface module 24 and are connected to the trailer brake control device 38 designed as a main control device 23, has further secondary data bus interfaces 52.
- a telematics system 54, a wireless interface module 56, an operating device 58 and a display device 60 are connected to the further secondary data bus interfaces 52.
- the telematics system 54, the wireless interface module 56, the operating device 58 and the display device 60 can each also be referred to as secondary control devices 62.
- the secondary control devices 62 are therefore used to carry out actuator-free functions 63, which correspond to functions 65 that are not relevant to safety.
- the secondary control devices 62 can also exchange data with other modules 64 of the towing vehicle 14 via the trailer interface module 24 and the first data connection 22 as well as the towing vehicle interface module 20.

- the safety-critical data 18 are sent via the main data bus 36 to the main control device 23, which is designed as a trailer brake control device 38, at least as long as the main data bus 36 is undisturbed. Friction brakes 68 or an electric drive 70, for example, are controlled by this safety-critical data 18, with the electric drive also being controlled via the Trailer brake control unit 38 can be done.
- the drive 70 is controlled via a further separate main control device 23.

- Safety-critical data 18 are therefore also sent from the towing vehicle brake control unit 16 of the towing vehicle 14 directly to the trailer brake control unit 38 via the third towing vehicle data interface 78.
- a data packet 94 is received from a trailer interface module 24.
- the trailer interface module 24 determines whether the data packet 94 includes safety-critical data 18 or non-critical data 66. If the data of the data packet 94 is non-critical data 66, these are sent out on a secondary data bus 42 in step 98 if they are intended for a secondary control device 62. If the data is safety-critical data 18 and it has been recognized in a previous step 100 that the main data bus 36 is undisturbed 102, then in a step 104 the safety-critical data 18 is sent to the trailer brake control unit 38 via the main data bus 36.
- step 100 If, on the other hand, it has been recognized in step 100 that the main data bus 36 is faulty 106, the safety-critical data 18 is sent to the trailer brake control unit 38 via the secondary data bus 42 in step 104.
- the trailer brake control device 38 detects safety-critical data 18 on the secondary data bus 42 in step 108, the trailer brake control device 38 determines its value in step 110 Data interface unit 40 whether the main data bus 36 is disturbed 106 or undisturbed 102.
- step 112 the data packet 94 is then processed if the main data bus 36 is disturbed 106 and discarded if the main data bus 36 is undisturbed 102.
