Definitions

  • the invention relates to a method for updating software, an electronic device, a system, a computer program and a computer program product.
  • An update of software-controlled and data-processing devices in motor vehicles is typically carried out via a diagnostic connection in a workshop or, as usual in navigation systems, by inserting a data carrier from which an updated software or updated data, for example, are read from a digital map.
  • this electronic device is provided with a transmission schedule, which provides information about which time for updating required package is provided with software, so that the electronic device is put into a ready to receive state at such time and the package is loaded with the software to the electronic device.
  • the software that is downloaded to the electronic device during the update can safely and consistently be integrated into an electronic device already existing
  • Stock of software, as the update, taking into account the schedule, may occur in a correct order depending on one or more versions of the software.
  • the transmission schedule is transmitted cyclically, ie at fixed times.
  • Transmission of the transmission schedule takes only a very short time compared to transmission of packets with software to be updated and can therefore be repeated in short successive cycles. A period of time in which the electronic device or the vehicle computer must be switched on to receive the transmission schedule is thus comparatively short.
  • the software provided by the method may include data, information, programs, eg, programs required for operation of the electronic device, and the like.
  • the transfer of software or data for a variety of versions must be possible. For this reason too, the transmission schedule is transmitted cyclically, in which case it is communicated which version of the software is made available for which update at which time.
  • the electronic control unit for example, the computer or a control device for a vehicle, refer to the transmission schedule, at which time a required for an update package can be received with software.
  • Information from the schedule may be set to a timing unit of the electronic device such that the electronic device is turned on for a selectable period of time at a selectable time and the update is performed during that time so that the packet is loaded onto the electronic device with the software.
  • the electronic equipment is set to the reception ready state at the time when the package required for the update is transmitted with software during a period required for the reception of the package with the software.
  • the method for an electronic device arranged in a device can be performed independently of an operating state of this device.
  • the method can be fully automatic, without the intervention of a user of the device, in the case of a vehicle without the driver's intervention.
  • the update of the software can be done while driving. But it is also possible that the update takes place when the vehicle is parked.
  • An ongoing update is made by turning off the device or turning off the device
  • the update is performed independently of a change in the operating state of the device or the vehicle.
  • the update will stop as soon as the required software or data is loaded on the controller. If the device or the vehicle is turned off or turned off during the update, a full charge of the
  • the transmission schedule and / or the software package in particular to the device in which the electronic device is arranged, can be transmitted wirelessly.
  • the transmission of the packets with software and the transmission plan can, for example, be carried out in a broadcast method, which is generally less expensive than a bidirectional service for the transmission of data or information.
  • the software in the electronic device can be updated via a wireless connection.
  • the software can be transferred in whole or in part.
  • Software already present in the electronic device can be replaced or modified by the software loaded during the update.
  • a tagged package with software is loaded into the electronic device.
  • the software package can be uniquely identified by the electronic device so as to avoid loading wrong software.
  • the updatable software electronic device is configured to receive a schedule that provides information about when a software package required to update the software is available.
  • this electronic device is adapted to put in such a time in a ready-to-receive state and to load the package with the software.
  • a user of an electronic device designed as a navigation system can use a current version of a digital map, which can be used as a transferable software is available. Changes in this card are wirelessly transmitted, received by the electronic device and inserted into a card already present in the navigation device as software. Thus, frequent replacement of data carriers such as CDs or DVDs to update the card and the associated costs can be avoided.
  • the invention takes into account that different versions of digital maps may be present in the navigation device. To incorporate changes securely and consistently into an existing database, the update takes place, depending on the schedule, if necessary, depending on the version and in the correct order.
  • the electronic device may, for example, be located in a vehicle and have a computing unit with a main memory, a non-volatile software memory, a control unit for automatic switching on and off, and a receiver which is designed for wireless reception of the package with software.
  • the electronic device may be a control device of the device or of the vehicle.
  • the electronic device is used as a navigation device for navigation purposes.
  • the electronic device in operation typically accesses data from a digital one
  • the electronic device stored on a disc such as a CD, DVD or hard disk. If the electronic device is designed as a control device or a computer for the device or the vehicle, then the software of the electronic device is stored in a non-volatile memory and is loaded from this non-volatile memory in the working memory before performing a function of the controller.
  • the system according to the invention has at least one transmitting device for, for example, wireless transmission or provision of a transmission schedule and a number of packets with software.
  • the software is suitable for updating a software present on an electronic device.
  • the schedule gives information on which time which package with which software is available.
  • the computer program with program code means according to the invention is intended to carry out all steps of the method according to the invention when this computer program is carried out on a computer or a corresponding computing device, in particular in the electronic device according to the invention or the system according to the invention.
  • the computer program product according to the invention with program code means which are stored on a computer-readable data carrier is intended to carry out the method according to the invention when the computer program is carried out on a computer or a corresponding computing device, in particular in the electronic device according to the invention or the system according to the invention.
  • Figure 1 shows an embodiment of an electronic device in a schematic representation.
  • FIG. 2 shows a schematic representation of an example of a transmission of a transmission device.
  • the figures are described coherently and comprehensively, the same reference numerals designate the same components.
  • the electronic device for example, a computer-controlled vehicle device, has, as shown schematically in Figure 1, a computing unit 5 with a memory 7, a non-volatile software memory 11, which is designed for non-volatile storage of software or data, a control unit for the time-dependent, automatic switching on and off of the electronic device 1 and a receiver 3 for a wireless connection to a transmitting device 17 of a service provider.
  • the electronic device 1 can further a control and
  • Output unit 13 for interaction with a user.
  • the electronic device 1 receives from the transmitting device 17 software which is broadcast unidirectionally in a broadcast mode.
  • the software can optionally be requested via a bidirectional connection.
  • the software may include data, information, programs, etc.
  • the software for a program sequence for operating the electronic device 1 is located on the arithmetic unit 5, in the working memory 7 or in the non-volatile
  • Memory 11 or is loaded from the non-volatile memory 11 for execution in the working memory 7.
  • FIG. 2 shows a schematic representation of an example of a transmission of software or information as provided by one or more transmitting devices 17 according to FIG.
  • the transmitting devices 17 emit different versions in the course of time t in individual packets, eg V2.0, V2.1, V3.0, V3.1, V3.2, V3.3, V3.4 of the software or data.
  • transmit schedules 15 are transmitted, which provide information about what time T A which package with which of the versions eg V2.0, V2.1, V3.0, V3.1, V3.2, V3.3, V3.4 the software is transmitted and how long a respective transmission takes.
  • the electronic device 1 receives via the receiver 9 the transmission schedule 15 with information about when updates of Software can be transmitted and thus can be received. Since the transmission schedule 15 is short compared to the software, this transmission schedule 15 can be transmitted much more frequently and cyclically. A one-time transmission of the transmission schedule 15 takes place during a period of time t z . During this period of time t z , the electronic device 1 must be turned on to receive the transmission schedule 15 to the maximum.
  • the electronic device 1 is informed about the time T A which packet is transmitted with which versions of the software or data by the transmitting devices 17.
  • the electronic device 1 can select from a plurality of packets to be transmitted with different versions of the software those required for updating the software or data respectively present in the electronic control unit 1.

  • control unit 9 is programmed by the arithmetic unit 5 in such a way that the control unit 9 switches the electronic device 1 on and off according to the times T A , T E predetermined by the transmission schedule 15.
  • the electronic device 1 needs new version V3.3 software for updating the existing software, it can be seen from the transmission schedule 15 that a transmission of a packet with this version V3.3 begins at time T A and Time T E ends, the transmission claims a period t v . Because those limiting the transfer of the package with software
  • Timing points T A and T E are known in advance by the transmission schedule 15, the electronic device 1 is offset by the control unit 9 from the time T A for the period t v in a ready to receive state.
  • the time span t z which the electronic device 1 must wait a maximum for receiving the transmission schedule 15 and must be turned on for this purpose, is compared to a waiting time t w to receive the required version
  • the transmission schedule 15 is completely radiated at least once within a time interval t y . This means that between a beginning of a Transmission of a first and a start of a transmission of an immediately following transmission schedule 15 the time interval t y is not exceeded. Accordingly, the time interval t y between an end of a transmission of a first and an end of a transmission of an immediately following transmission schedule 15 is not exceeded.
  • the electronic device 1 takes from the transmission schedule 15 the transmission times T A required for the required data and sets the control unit 9 so that the electronic device 1 is automatically switched on in time for reception, provided that it is not already in operation.
