Definitions

  • the invention relates to a control device according to the preamble of claim 1, an external device according to the preamble of claim 4 and a method for activating and / or expanding and / or modifying software modules or parts of a software module.
  • the vehicle network is connected to an external unit via a so-called diagnostic connector and a cable (production or service tool ,,) - which transmits data to the individual control units and which data receives from the control unit.
  • a so-called diagnostic connector and a cable production or service tool ,,
  • the invention has for its object to improve the communication between the control devices of a vehicle and an external device.
  • activation and / or expansion and / or modification of software modules or parts of a software module can be carried out.
  • a functional improvement, functional expansion, functional activation of software can be brought about.
  • new software functions can be transferred to the control unit.
  • status information can also be transmitted via the existing control unit (eg OES status; original equipment supplier). So it is possible, among other things, that the end customer of a software can obtain the corresponding "software product" directly from the manufacturer without going through the workshop.
  • wireless communication is used to transmit the information.
  • the vehicle network bus system
  • an external device e.g. production or service tool
  • the wireless control unit access gives the opportunity to transmit information during vehicle production. This eliminates the usual connection between the vehicle and a "production or service tool" with a data cable. In addition, for the first time, data transmission can also be carried out particularly easily over several production steps. This brings in particular Programming advantages (, flashing); Coding (eg adaptation to vehicle variant); Compatibility management (hardware and software); Tracking, recording and analysis of processes (tracking) and for testing the control units, as well as for the calibration of connected sensors and actuators.
  • the wireless control unit access enables error diagnosis (e.g. "On Board” diagnosis), coding (e.g. activation of additional functions) when you are in the workshop.
  • error diagnosis e.g. "On Board” diagnosis
  • coding e.g. activation of additional functions
  • updates updates
  • additional functions upgrades
  • the method for wireless communication is set up in such a way that it is suitable for communication over distances of more than approximately 5 km. This results in largely location-independent wireless control device access over long distances. In this way it is possible to carry out the above updates even without a visit to the workshop, either with or without customer request.
  • transmitter / receiver units (cell phone networks, cell phones, etc.) that are already in the vehicle to carry out the method according to the invention.
  • transmitter / receiver units cell phone networks, cell phones, etc.
  • a combination with the following devices in the vehicle is possible: Keyless entry device (Keyless Entry) Direct tire pressure monitoring (radio link between sensor and receiver, TPMS) Mobile or car phone (cell-phone)
  • a connection between the control device and an additional hardware resource can preferably be established via a bus or a network. This connection is controlled by telemetry. Data transmitted to the vehicle (e.g. downloads) is particularly preferably transferred to the new resource at a later point in time.
  • the vehicle mentioned above is preferably a motor vehicle which is equipped with at least one electronic control device, such as an electronic brake control device.
  • the motor vehicle can be a passenger vehicle or a truck.
  • the software module which is modified or installed according to the invention, is preferably a method for detecting a tire pressure loss on the basis of the wheel speed information (so-called indirectly measuring tire pressure loss detection system; DDS).
  • the software module can also be any other software functions that are carried out in control units, such as ABS (anti-lock braking system), ASR (traction control system), ESP (electronic stability program) and TPMS (tire pressure control based on pressure sensors located in the tire).
  • the desired software module (upgrade, patch, new version, etc.) is kept in an application management database for the operators of the control devices (in particular motor vehicle customers), so that the customer can do this as desired can be downloaded directly (download).
  • the suppliers preferably have an interface via which they can communicate if necessary to change the content of the application management database.
  • every data transmission process is protected against access by third parties (eavesdropping, eavesdropping) by suitable measures such as encryption.
  • the control device or other suitable devices within the motor vehicle communicate with the application management database.
  • data about the vehicle type and / or about the configuration in the vehicle are transmitted from the vehicle to the application management database, so that the suitable version of the software module can be determined independently by the application management database.
  • the vehicle customer only needs to state which type of application is to be changed. Version-dependent or vehicle-dependent entries are then not required.
  • FIG. 1 shows a motor vehicle which can communicate with an application management database via a wireless telemetry device.
  • Motor vehicle 2 includes an electronic brake control device 1, which contains a microcontroller and a changeable ROM memory (e.g. flash ROM) for performing a wide variety of control and regulation tasks (ABS, ESP etc.).
  • the control unit is connected to other electronic hardware devices 4, 10 via CAN bus 9.
  • 4 denotes a mobile radio device with antenna 6 for communication with the outside world.
  • Memory 10 is also connected to CAN bus 9 by means of interface electronics.

Abstract

Selon l'invention, une communication sans fil est établie au moyen d'un dispositif télémétrique (4-7) à l'aide d'un appareil de commande (1), notamment dans un véhicule automobile (2), qui comprend une interface (8) servant à l'activation, à l'extension et/ou à la modification par un appareil externe (3) de modules logiciels ou de parties d'un module logiciel qui sont stockés à l'intérieur d'une mémoire de l'appareil de commande. Il est ainsi possible d'exécuter des extensions et des adaptations de logiciel de manière particulièrement simple.
