Definitions
- the invention relates to a method for determining incompatibilities in a bus system of a motor vehicle, which has a plurality of control units, according to the preamble of claim 1.
- Incompatibilities can arise from the installation of control units of different development levels, especially if the vehicle is repaired improperly. Incompatibilities can impair the functionality of the vehicle. The problem is that they may not be obvious and lead to errors in a way that is hardly predictable.
- the object of the invention is to create a method in order to be able to reliably detect incompatibilities in a bus system with a plurality of control devices in a motor vehicle to a large extent reliably.
- control device identification information or an identifier that identifies the type of control device in question is stored.
- the control unit identification information or the identifier allows, in particular, a conclusion to be drawn about the functional sequences carried out by the control unit concerned and / or the hardware version of the control unit concerned.
- version information identifying the sequence control of the control device in question is also stored.
- the version information allows, in particular, a conclusion to be drawn about the functional sequences carried out by the relevant control unit and / or the topicality of the sequence control and / or the hardware version of the relevant control unit.
- the first control device transmits its first control device identification information and / or its first version information to the second control device.
- the second control device accesses a compatibility reference table, which is preferably stored in the second control device.
- the compatibility reference table specifies which combinations of control unit identification information and version information and thus which control units and their relevant sequence controls will communicate with the second control unit in a compatible or tested manner.
- a control device is understood to mean in particular a physical control device which has one or more software modules. Each software module performs at least one function. In other words, each physical control unit then forms an o of multiple virtual control units. In control units that have been more common up to now, each control unit performs only a single function. For example, there are separate physical control devices for engine control and for energy management of a vehicle.
- a control device of the invention is a device with at least one data processor and at least one volatile memory, the processor or processors executing the one or more software modules.
- the second control device also transmits its control device identification information and its version information to the first control device.
- this method allows the decentralized detection of incompatibilities when using several control devices in a communication network or in a bus system of a motor vehicle. Not only is the compatibility between two control units checked, but each control unit checks the compatibility with the other control unit. Before a communication connection is established between two control units, two independent compatibility tests are preferably carried out, which significantly increases the reliability of a bus system which uses the method according to the invention. Malfunctions, especially in safety-critical areas, can be avoided.
- the decentralized solution according to the invention does not require an additional control device. Only the bus load and the memory requirement increase slightly.
- the one control device transmits its control device identification information and its version information to the other control device when the other control device requests this. This makes it possible to carry out the compatibility check as required and at a suitable point in time, for example when the requesting or requesting control unit is “idling”.
- the first control device transmits its control device identification information and / or its version information, promptly or unsolicited, to largely all other control devices in the bus system for checking the compatibility.
- the transmission is carried out periodically and / or at the request of other control units and / or when the bus load is low and / or before the motor vehicle is started up.
- ⁇ 20 In a further embodiment of the invention is merely transmits the version information of the corresponding control device, when only one logical interface is provided between the control units. This is the case if several control units or their sequential controls run on the same hardware.
- each control device compares the control device identification information and / or version information transmitted by one or more other control devices with the compatibility reference table assigned to it or with its entries.
- the compatibility reference table is preferably stored or stored in the memory of the respective control device.
- each control device compares the received version information with the entries in the compatibility reference table and communicates (only) in a compatible manner if there is a match with the sending control device.
- the receiving control unit uses the received control unit identification information to determine whether there is an entry for the sending control unit in the compatibility reference table, which is stored in particular in the receiving control unit, and, if appropriate, which version information under the entry are listed. In the next step, the received version information is compared with the version information listed under the entry for checking for compliance.
- the received version information does not match the version information listed under the entry, because the version information in the form of a version number is higher and / or more current than the recorded version information or the recorded version number is so
- the receiving control device communicates with the sending control device even if the version number is higher and / or more current than the version number entered in the compatibility reference table.
- the receiving control unit in question and / or the transmitting control unit in question generates an error message and / or refused the service and / or only carried out restricted or emergency operation.
- the invention also enables an advantageous bus system with a plurality of control devices, which detects incompatibilities among the control devices by executing a method according to the invention.
- the invention also enables a computer program product for ascertaining incompatibilities in a bus system with a plurality of control devices, which is arranged in a motor vehicle by causing the method according to the invention to be carried out.
