System and method for using a mobile terminal in a motor vehicle for updating the software of on-board computers
First Claim
1. A system, comprising:
- at least one mobile terminal, wherein the mobile terminal is a mobile telephone, a personal digital assistant, a notebook computer, or a mobile entertainment device;
a motor vehicle, coupled to the at least one mobile terminal by a communication interface;
a software version transmission device provided in the mobile terminal and arranged to transmit a software version message,wherein the software version transmission device specifies which sequence controllers and/or control unit data are to be stored and/or installed in one or more control units of the motor vehicle,wherein the software version message is transmitted to the mobile terminal and to a vehicle-external download device by the software version transmission device upon a technical error of the vehicle, which results in an entry in the error memory of the control unit,wherein the software version message is analyzed to ascertain whether the vehicle-external download device has one or more current sequence controllers and/or control unit data ready for downloading,wherein the one or more current sequence controllers and/or control unit data are downloaded via a communication link and the downloaded sequence controllers and/or control unit data are stored in the mobile terminal, andwherein the system also includes an updating device, which stores and/or installs the sequence controllers and/or control unit data stored in the mobile terminal in at least one affected control unit.

Abstract
A system for using at least one mobile terminal in a motor vehicle, such as a passenger automobile or a two-wheeled vehicle in particular, having the at least one mobile terminal and a communication interface between the motor vehicle and the mobile terminal is provided. A software version transmission device transmits a software version message indicating which sequence controllers and/or control unit data are stored and/or installed in one or more control units of the motor vehicle. The software version message is analyzed to ascertain whether the vehicle-external download device has one or more current sequence controllers and/or control unit data ready for downloading, which are downloaded via a communication link and stored in the mobile terminal. An updating device stores and/or installs the sequence controllers and/or control unit data stored in the mobile terminal in the at least one affected control unit.

13. A method, comprising the acts of:
-
transmitting, by a software version transmission device provided in a mobile terminal that is a mobile telephone, a personal digital assistant, a notebook computer, or a mobile entertainment device, a software version message to the mobile terminal and/or to a motor vehicle-external download device upon a technical error of the motor vehicle, which results in an entry in an error memory of a control unit, the software version transmission device specifying which sequence controllers and/or control unit data are to be stored and/or installed in one or more control units of the motor vehicle; analyzing the software version message to ascertain whether the vehicle-external download device has one or more current sequence controllers and/or control unit data ready for downloading, downloading, via a communication link, the one or more current sequence controllers and/or control unit data; storing the downloaded sequence controllers and/or control unit data in the mobile terminal, and storing and/or installing, by an updating device, the sequence controllers and/or control unit data stored in the mobile terminal in the at least one affected control unit. - View Dependent Claims (14, 15, 16, 17, 18)
