Definitions
- the invention relates to a method and a device for vehicle-typical programming of vehicle control units.
- the aim of the invention is to be able to program vehicle control devices such as engine control, transmission control, ABS control, airbag control and driving dynamics control during production according to the vehicle type.
- vehicle control devices such as engine control, transmission control, ABS control, airbag control and driving dynamics control during production according to the vehicle type.
- DE 43 34 859 A1 discloses a device for programming electronic control units in motor vehicles.
- the task of this device is to enable testing and programming of electronic control devices in motor vehicles without the need for cable connections.
- this device makes use of a communication-capable control device which has a transmitting / receiving unit and which can be queried and programmed wirelessly by an external programming device via the transmitting / receiving unit.
- This device is designed so that it can program the vehicle at least for test purposes before leaving the production line. This means that all communication-capable control units can be programmed during the production of the vehicle.
- the use of a radio wave connection between the motor vehicle and the external programming device eliminates the use of a cable connection which is sensitive to moisture and wears out quickly.
- Vehicles of different types are produced in today's production facilities.
- the use of different engines, for example, results in a large variety of types, which requires a large number of control units for individual vehicle parts with different software when different control units interact with one another. It follows that the storage of this large number of control units is complicated. This results in an additional source of error during vehicle assembly, since an incorrect control unit for the respective vehicle type is installed very quickly.
- the object of the invention is to enable a vehicle-typical programming of vehicle control devices during production.
- the object derived and shown above is achieved according to the invention by a method in which during the production of a motor vehicle, in particular when leaving the production line, at least one identifier is transmitted by the motor vehicle, in which the identifier is received by an external programming device, and / or by the external programming device is read by the motor vehicle, in which, with the aid of the programming device, at least one control unit and / or vehicle-typical control unit software is sent as a function of the received or read identifier, in which the control unit and / or vehicle-typical control unit software is transmitted by the Motor vehicle is received, and in which at least one control unit of the motor vehicle is programmed with at least one of the at least one received control unit and / or vehicle-typical control unit software.
- the identifier that is transmitted by the motor vehicle uniquely identifies at least one of the vehicle control units and / or the type of the motor vehicle, and / or also the motor vehicle itself, in relation to the external programming device. All possible control unit software variants are stored in the external programming device. Using the at least one control unit and / or motor vehicle or motor vehicle type identified by the identifier, the programming device determines the required control unit software, which is then sent to the motor vehicle and received there. In the motor vehicle itself, at least one of the control units is programmed with the corresponding control unit software adapted to the control unit and / or the vehicle type and / or the individual vehicle. By programming the control units according to the vehicle during assembly, it is no longer necessary to keep different control unit variants in stock for the individual control units.
- the control units are preferably programmed with at least basic software that enables the installation of control unit and / or vehicle-typical software.
- This basic software also makes it possible, for example, to identify the type of control unit, such as an engine control unit, transmission control unit, airbag control unit, ABS control unit or vehicle dynamics control unit.
- the corresponding control unit is programmed with this control unit software.
- the control unit is then configured for use in the respective vehicle.
- the advantage of the solution according to the invention lies on the one hand in cost-effective storage, and on the other hand in a low probability of errors when installing the control units.
- the software of the control units can be adapted very flexibly to different requirements. This means there are no overhangs in the warehouse and the evolution cycles of vehicles or vehicle types are shortened.
- an identifier is sent by at least one control unit or is read by the control unit through the programming device.
- each of the control devices arranged in the motor vehicle and programmable by a vehicle-typical control device software can send an identifier to the external programming device or read it from it.
- the external programming device can use the individual control unit identifiers to select the appropriate control unit software and send it back to the respective control units. It is also conceivable here that several control units are combined to form a group, each group having its own transceiver. The control unit identifiers are then sent out or read by this transmission / reception unit and the respective vehicle-specific control unit software is received.
- the programmable control units are connected to the transmitting / receiving unit, for example, via a data line.
- the transmitting / receiving unit transmits to the external programming device a control device and / or vehicle identifier, with the aid of which the programming device can determine the respective control device and / or the vehicle and / or the vehicle type. Accordingly, the control unit software for the respective control units is sent back to the transmitting unit and from there forwarded to the control units to be programmed.
- a particularly simple transmission of the vehicle-specific control unit software is achieved in that the identifier and / or the control unit software is transmitted wirelessly between the motor vehicle and the programming device. Through the wireless transmission, the transmission cable can be saved, which would have to be laid additionally. It is an advantageous embodiment of the wireless transmission that the identifier and / or the control unit software is transmitted between the motor vehicle and the programming device with the aid of electromagnetic waves.
- An advantageous wireless transmission using electromagnetic waves is the transmission using the “Bluetooth transmission standard”.
- the “Bluetooth standard” is known, for example, from www.teltarif.de/i/bluetooth.html from January 2, 20002.
- the "Bluetooth transmission standard” enables data transmission via radio waves.
- the Industrial Scientific Medical (ISM) radio network with 2.45 gigahertz is used.
- the data transmission rate is up to 1 megabit per second with a range of approx. 10 m.
- Another option for wireless data transmission is the transmission of the identifier and / or control unit software between the motor vehicle and the programming device with the aid of an infrared signal.
- At least one identifier and / or at least one control unit software be transmitted between at least one motor vehicle and the programming device using a multiplex method. It is thus possible that several control units can be programmed with the control unit software essentially simultaneously.
- the control units can be arranged in a motor vehicle and the control units arranged in the motor vehicle are simultaneously supplied with the control unit software intended for them via the multiplex method.
- the control devices arranged in the respective vehicles can thus also call up the respective control device software.
- a time-division multiplex method, a code-division multiplex method or also a frequency-division multiplex method can be used as the multiplex method.
- At least one identifier and / or at least one control unit software be transmitted between at least one motor vehicle and the programming device with the aid of a packet-switched transmission method.
- a packet-switched transmission method For example, in a time division multiplex method, only part of the entire control unit software is transmitted in each time slot. The data are packed into individual data packets and the individual data packets are each transmitted separately to the control unit via the carrier channel.
- at least one ECU software is transferred using the point-to-multipoint method.
- the programming device sends out the control software for all control devices of the same type and all control devices located in the reception area of the programming device receive the control device software.
- Another object of the invention is a device for the control unit and / or vehicle-typical programming of vehicle control units, wherein a motor vehicle has at least one control unit that controls a vehicle function, the motor vehicle having a transmitter / receiver unit that enables communication with an external programming device, which is thereby characterized indicates that at least one control unit and / or the motor vehicle has at least one identifier, the transmitting unit sending the at least one identifier to the programming device or the programming device reading the identifier that the programming device, depending on the identifier, has at least one control device and / or vehicle-typical Control unit software transmits, and wherein the at least one control unit software programs at least one control unit in a control unit and / or vehicle-typical manner.
- This device enables the method according to the invention to be used.
- the use of this device results in enormous cost-saving effects, since only control devices of a basic type have to be stored for the respective vehicle elements. Errors due to incorrect installation of a control unit that does not match the respective vehicle type can be excluded.
- a control device can be addressed separately by the external programming device if at least the one control device has a transmitting unit.
- the respective control unit can send an identifier to the programming device with the aid of the transmitting unit, or the programming device reads the identifier.
- the programming device recognizes the respective vehicle type or control device type on the basis of the identifier and supplies the respective control device with the control device and / or vehicle-typical control device software. It is also conceivable that each individual control device has its own identifier.
- a transmission unit several control units can be combined into a group, the entire group using the one transmission unit present in the group.
- At least one control unit is programmed with an initial configuration and that the received vehicle-typical control unit software programs the control unit in a vehicle-typical manner makes it possible to install only basic control units in the respective vehicle types.
- the basic control units are then programmed using the control unit software typical of the vehicle, depending on the control unit type.

- the method illustrated in FIG. 1 functions as follows:
- the vehicle 100 sends an identifier to the programming device 102 via the air interface 130 with the aid of the transmitting / receiving unit 110.
- This identifier serves to uniquely identify the vehicle 100 this to the computing unit 106.
- the received identifier is processed in the computing unit 106.
- the vehicle type is determined from the identifier and the components 113, 115, 117 and 119 mounted in this vehicle type are determined.
- the computing unit 106 inquires in the database 108 the control programs required for the corresponding components 113, 115, 117 and 119. All control programs for the different types of components 113, 115, 117, 119, 123, 125, 126 and 129 are stored in database 108.
- the associated control unit software is retrieved from the database 108 by the computing unit 106. With the aid of the transmission unit 104, the programming device 102 sends the control unit software required for the respective control units 112, 114, 116, 118 to the transmission unit 110 of the vehicle 100 via the interface 130. The received control unit software is imported into control units 112, 114, 116 and 118.
