Definitions
- the invention relates to a bus system in a motor vehicle with at least one first bus having control units as bus subscribers, according to the preamble of claim 1.
- a vehicle-external diagnostic device in particular in a vehicle workshop, via an interface of the motor vehicle a specific diagnostic command on the bus system and thereby speaks a stored in the addressed control unit diagnosis Algorithm.
- the diagnostic algorithm checks the operability of the respective controller and gives a corresponding message to the bus system, which is received and evaluated by the diagnostic device. Furthermore, the diagnostic device reads out the error memories of control units to be checked.
- the known procedure or the known bus system is not very flexible, because the diagnostic algorithms for self-testing of the control devices are virtually unchangeable or expandable. This is particularly disadvantageous in the case of a large number of networked control devices which interact with one another.
- the object of the invention is to provide a bus system that is more flexible with regard to fault diagnosis.
- the essence of the invention is that at least one gateway device is provided with an access control device as an external vehicle access at least to the first bus and the control units connected to it.
- the gateway device according to the invention is brought into a diagnostic mode in which, in contrast to an operating mode of the gateway device, which is activated during the regular operation of the motor vehicle, under the control of the gateway device at least a first bus Message is supplied to at least a first control device of the control units.
- the first bus message at least largely corresponds to a bus message which the first control unit also receives during regular operation of the motor vehicle.
- one or more regular bus messages in particular from an external diagnostic device, can be fed to one or more control devices and their behavior under typical bus message conditions in the bus system can be investigated, in particular for the determination of faulty control devices or bus components.
- the first control unit emits a first response message following receipt of the first bus message.
- the first response message at least largely corresponds to a bus message which the first control unit also transmits during normal operation of the motor vehicle.
- the first response message is supplied via the gateway device to a vehicle-external diagnostic device.
- the vehicle-external diagnostic device preferably transmits to the gateway device the first bus message for forwarding to the first control device.
- the first bus message is a bus message of a plurality of bus messages of a bus message packet and the bus message packet represents a sequence of bus messages that the first control device and / or other control devices are supplied.
- the response messages of the first and / or the further control units triggered thereby are checked by the diagnosis device to determine whether they correspond to the response messages which occur during regular operation of the motor vehicle with proper functioning of the first control device or with proper functioning of the first control device addressed control devices are emitted by the first control unit or by the addressed control units.
- a plurality of such analysis scenarios for various fault images of the bus system can be stored or stored in the vehicle-external diagnostic device, in particular a laptop computer or a personal computer.
- a library of analysis scenarios on the vehicle-external diagnostic device can be kept up to date in a technically quite simple manner by means of a data connection with an always current corresponding library, in particular at the vehicle manufacturer.
- a particularly specialized technician may in difficult cases, via a suitable data connection with the gateway device, carry out a remote analysis by transmitting adapted analysis scenarios, relieving the technician in the vehicle workshop.
- the bus message packet represents a sequence of simulated switch actuations and / or simulated driving conditions of the motor vehicle, such as in terms of speed, acceleration or temperature.
- the access control device of the gateway device carries out an identity check or authentication check of the diagnostic device in order to determine whether the diagnostic device is deemed to be entitled to bring about the diagnosis mode and to address the control units with bus messages.
- an identity check or authentication check of the diagnostic device By means of the authentication check according to the invention, manipulations of the bus system can be reliably prevented.
- the appropriately designed gateway device checks whether the motor vehicle is in its regular operating state and, if appropriate, prevents the gateway device from being brought into the diagnostic mode during the regular operating state of the motor vehicle ,
- the gateway device checks whether the motor vehicle is currently being used by a driver for locomotion and possibly prevents the gateway device from activating the diagnostic mode.
- the invention further describes a method for diagnosing a fault in the bus system according to the invention, in which the diagnostic device is a portable or mobile computer operated in a vehicle workshop, which communicates with the gateway device via an interface, in particular an Ethernet - Interface, data technology is connected.
- the diagnostic device authenticates against. the gateway device as authorized access to the bus system in the context of an authentication check made by the gateway device.
- the gateway device forwards the bus messages received from the portable or mobile computer to one or more controllers of the bus system.
- the inventive method for diagnosing a fault in the bus system according to the invention enables a reliable diagnosis without the risk of manipulation in the environment of a vehicle workshop.
- the invention further describes a method for diagnosing a fault in the bus system according to the invention, in which the diagnostic device is a portable or mobile computer operated in a vehicle production facility, which communicates with the gateway device via an interface, in particular an Ethernet - Interface, data technology is connected.
- the portable or mobile computer authenticates against. the gateway device as authorized access to the bus system in the context of a made by the gateway device authentication check.
- the gateway device forwards the bus messages received from the portable computer to one or more controllers of the bus system.
- the method according to the invention for diagnosing a fault in the bus system according to the invention enables a reliable diagnosis without the risk of manipulation in the environment of a vehicle production facility. Likewise, it can already be checked in the course of production on the basis of corresponding bus messages that are given to the bus system, whether the already installed control devices or bus subscribers, such as a windshield wiper, are operated and work properly.
