Description

  The present invention relates to a method and apparatus for detecting and / or transmitting vehicle service data and diagnostic data between a vehicle and a factory management system.

  From EP-A-0978805 and EP-A-08106022, devices for automatically processing service orders are known. Here, the user manually inputs necessary data into the system. The execution of the appropriate service order to meet the individual requirements of the vehicle assumes that the inquired data is correctly entered and that the user has knowledge of the replenishment and repair work that may be required. It is said.

  Accordingly, an object of the present invention is to enable an appropriate service to be executed quickly and reliably without imposing a burden on the user.

  The challenge is to detect and register vehicle ID data in a non-contact manner when the vehicle is staying in the factory area, and then to detect operation data, service data and diagnostic data from the factory management system to the vehicle. This is solved by sending a request command for transmission and then evaluating the operational data, service data and diagnostic data detected and transmitted from the vehicle with a factory management system.

  Unlike known methods for simplifying the processing of service orders, the present invention automatically detects and registers vehicle ID data without contact, and subsequently registers operation data, service data and diagnostic data without contact. It is transmitted to the management system. The user does not need to prepare a document in which data is written or manually input, and an error due to an erroneous input is avoided.

  Further, all the criteria necessary for the maintenance work and the repair work are autonomously inquired and answered, and can be used regardless of the knowledge of individual users. Furthermore, electronic data transmission is much faster than manual entry. Therefore, a plurality of users can use data simultaneously or in a time multiplexed manner. This eliminates the waiting time, or the user does not have to assume the waiting time when setting the service date.

  Advantageous embodiments of the invention result from the dependent claims.

  Advantageously, the detection of the vehicle ID data is reported in the vehicle and registration of the vehicle ID data is performed after obtaining the enable command.

  This measure is for data protection and to ensure freedom of personal decision. Thus, the user does not need to monitor whether or not the vehicle data is registered, and for example, it is possible to search for another means different from the service request for the vehicle.

  Also advantageously, the ID data, operational data, service data and diagnostic data are compared with data of the same type of vehicle stored in the data bank, and maintenance and repair work to be performed are controlled based on the comparison results. The

  As a result, all of the data is used to control maintenance and repair operations to be performed directly without intermediate circuits for manual transmission or manual input. Human input or transmission errors are avoided.

  In order to control the maintenance and repair work to be performed, additional data is evaluated when the vehicle has previously stayed in the factory.

  As a result, work that is necessary but not yet executed is performed, and it is avoided that work already performed is performed again. Therefore, repair requests are effectively covered in a short period of time.

  Further, the calculation of the maintenance time and the repair time is controlled, and the collection date is calculated from the maintenance time, the repair time and the date at that time. In addition, calculation of maintenance costs and repair costs is also controlled.

  The user receives all the data necessary to make a decision regarding order authorization. The user can recognize the calculated due date and cost and build a corresponding plan. Since time and costs are determined automatically, very accurate calculations can be made based on a duty contract between the user and the factory.

  Advantageously, maintenance time, repair time, maintenance costs and repair costs are displayed and authorization orders transmitted to the factory management system permit maintenance orders and repair orders.

  This ensures that maintenance orders and repair orders are only permitted by the user expressing the authorization with knowledge of the time and expense associated with the offer, not simply by bringing them into the factory area.

  In addition, factory resources and material procurement are controlled in the factory management system.

  This allows maintenance and repair operations to be performed as needed without manual intervention and without time delays.

  Embodiments of the invention are illustrated and described in detail below.

  FIG. 1 shows a block diagram of two components. As components on the vehicle side, a control device 1 having a diagnosis node, an off-board diagnosis unit OBDE or a telematics terminal TE having an input / output device 2 called a man-machine interface HMI, and a communication module 3 are provided. Yes. As a factory component, a central computer 5 having a communication module 4, a data bank 6 and an interface 7 and an automatic receiving device (Annahmeautomat) 8 for keys are provided.

  Vehicle-side components are incorporated as additional hardware and / or software in car radios, driver information systems, gateways and others. Factory-side components are built into or connected to a stationary factory management system. Communication between the vehicle and the factory takes place in several phases.

I)
When the vehicle stays in the factory area, the ID data of the vehicle, for example, the model, year and owner name of the vehicle is detected by the control device 1, the off-board diagnostic unit OBDE or the telematics terminal TE2, and is contactless. Are transmitted between the communication modules 3 and 4 via, for example, Bluetooth or WLAN, and detected and registered by the factory management system. The user 9 of the vehicle is notified of the detection or transmission, and can decide whether or not to permit data registration. Registration and use of data is triggered by a central computer of the factory management system by an enable command via the input / output device 2.

  Whether or not the vehicle stays in the factory area is detected by comparing the position of the vehicle detected by a position detection device in the vehicle, for example, GPS, and the position of the factory. Alternatively or additionally, detection of whether the vehicle is staying in the factory area may be identified by a corresponding input from the user (driver). This can be done by activating the corresponding function and / or activating communication between the vehicle and the factory management system. For example, pulses are transmitted between vehicle-side components and / or factory management systems.

II)
After the user enables the data in the factory area and the vehicle ID data is detected, the operation data, service data and diagnostic data formed in the network inside the vehicle are sent to the onboard diagnostic unit OBDE or Inquiries are made via the telematics terminal TE. This inquiry is encoded (or encrypted) and transmitted via the contactless communication module 3 of the vehicle, and received and decrypted by the contactless communication module 4 of the factory management system. This is done by comparing with the data in bank 6. At this time, both data from a data bank provided for each vehicle type and data obtained when the vehicle has previously visited the factory are used. The central computer 5 can access other external computers or servers via the interface 7. The request command is automatically formed by the factory management system and transmitted to the vehicle via a wireless communication connection.

  The communication modules 3 and 4 perform communication via an arbitrary contactless communication interface such as Bluetooth, WLAN, GSM, GPRS, and UMTS. The result of the comparison or evaluation is transmitted to the input / output device 2 in the vehicle and displayed to the user. At this time, the result of the comparison or evaluation is transmitted from the factory management system to the vehicle via the communication interface and displayed there. In addition, the estimated cost to carry out planned maintenance and repair work and vehicle take-over dates are communicated.

III)
The user 9 determines whether to perform the presented maintenance work and repair work. When working, the user leaves the vehicle and stores the key in the auto-acceptor 8 for service order processing and transmits an authorization command to the automaton, or the driver himself enters the vehicle-side component. By doing this, the order permission can be transmitted to the factory management system.

  Instead of transmitting the planned maintenance work and repair work and the vehicle take-off date to the input / output device of the vehicle, the data can be transmitted to the input / output device of the automatic receiving device 8.

  Whenever the vehicle is in the factory, the user can be notified of the execution of service work and repair work, without the vehicle needing to output other individual additional information. As a result, the user can automatically know the time and cost required for the evaluation.

  In addition, resource planning takes place in the factory. In addition, materials and parts are procured automatically based on the detected diagnostic data.

It is a block diagram which shows the apparatus of this invention.
