  • a system is a combination of different elements (logical circuits, timing, automatic start-up, microtechnical sensors, etc.) that together provide a specific functionality, for example an acceleration sensor including evaluation electronics. SoCs are usually used in embedded systems.
  • SiP system-in-package
  • SoCs are used in mobile devices such as smartphones, tablet computers, other gadgets and data acquisition devices, as well as in control and automation technology (e.g. washing machines, automotive electronics, industrial automation) and in all kinds of modern consumer electronics devices. mostly are to operate many different interfaces (sensors, actuators, networks, buttons, displays) and the quantities are large.
  • the integration of functions that were previously distributed over several components or even several printed circuit boards can also increase reliability and functional safety, especially if a variety of fault detection measures are integrated that would not be marketable with discrete components.
  • Specially adapted SoCs are rarely used for applications that generate smaller quantities, such as in medical technology or avionics, and many of the integrated modules often remain unused.
  • SoCs are mostly not developed from scratch, but the designs are based - at least in part - on existing or purchased components, so-called IP cores. These are, for example, macros for full CPU cores, or coprocessors - such as hardware accelerators for encryption or graphics calculations. Likewise, these are peripheral blocks for the implementation of storage, Ethernet, Bluetooth or other interfaces, or complete storage units including their management.
  • IP cores can often be generated via parameters adapted to the intended use, for example in the form of the pipeline length, the cache size or the bus bit widths.
  • SoCs have a debug interface. This is often a simple RS-232 interface, but USB is increasingly used here as well. Error messages and general information can then be output via this debug interface during operation, for example on a terminal, i.e. a console application. In more complex environments, this function is often also performed by a JTAG interface. This is typically used not only to transmit error messages, but also to communicate with a FLARD or software debug module in the SoC.
  • Such a module allows the user, for example, to "stop” the SoC and carry out the processing in the CPU core in single-step mode ("step-by-step") and, if necessary, to change individual register values or, for example, to shorten a loop or a jump instruction evade.
  • This interface is the programming of programmable areas of a SoC, e.g. B.RAM, EEPROM, Flash or even individual circuit parts up to the entire SoC design (only in an FPGA or similar).
  • Other external components are usually attached as a "chain" to the same JTAG interface, which are addressed via a so-called boundary scan.
  • the individual boxes or a box can be manufactured monolithically integrated with one another on a common substrate, for example a silicon substrate. It is conceivable that all boxes, i. H. all processing and data units are arranged and installed on a single chip, for example on a SoC monolith, in particular monolithically integrated.
  • the security ECU further in particular monolithically integrated, can also be based on a SoC principle and in particular also on a common substrate be generated monolithically integrated together with the other boxes or at least one of the boxes.
  • a data error or a deviating data structure can be identified as data compression in the sense of the present application.
  • a data error is, among other things, a virus or faulty software that leads to a malfunction of at least one of the components of the vehicle data communication system described here.
  • Such data compression can therefore be filtered out by the security ECU. If the data sent from the MC box to the safety ECU contains a corresponding data compression, this data is not forwarded to the BSC box at all and/or only partially, for example.
  • the security ECU repairs the corresponding data compression and/or cuts it out of the data stream in terms of data or software and only then forwards a correspondingly decompressed data set, i.e. one that has been freed from the corresponding software error, to the BSC box.
  • the security ECU forms a so-called “door opener” or “gate keeper”, which prevents the MC box, which is supplied with data or compressed, for example for corresponding downloads or USB connections, corresponding compressed messages not forwarded to the BSC box.
  • Data exchange between the security ECU and the MC box is preferably bidirectional. This can mean that in the event of an error being detected by the safety ECU, it supplies an error code, for example an error alarm, to the MC box and the MC box therefore corrected accordingly in this case, i. H. error-free data or no further data stream at all to the safety ECU. For example, if an error is detected, a data stream that is still being transmitted from the MC box to the security ECU can then be interrupted.
  • an error code for example an error alarm
  • the interruption can therefore be remedied either by the MC box or by the safety ECU, in particular by mutual agreement on data technology, or it can also be sent back to the MC box by the safety ECU.
  • a data transfer between the BSC box and the MC box can only be routed directly, i.e. without being redirected via the security ECU, if data is sent from the BSC box to the MC box.
  • the BSC box exchanges data, preferably bidirectional data exchange, with a vehicle safety system, for example an airbag controller, the BXC box exchanges data with an emergency seat controller, an emergency braking system and/or another vehicle assistance system.

  • the BXC box exchanges data with an emergency seat controller, an emergency braking system and/or another vehicle assistance system.
  • data communication between the BSC box and the MC box can be unidirectional, i. H. exclusively starting from the BSC box to the MC box.
  • a direct exchange of data between the MC box and the BSC box is therefore excluded in at least one embodiment of the above-mentioned invention. This ensures that the MC-Box cannot communicate directly with the BSC-Box and then transmit any error data or even viruses to the BSC-Box.
  • only communication from the MC box to the BSC box can take place via the security ECU.
  • the IP box is in data exchange with a charging station and/or a vehicle battery, in particular in order to be able to charge the vehicle battery.

  • the BSC box can take over the functions of passenger well-being.

  • a system or a data set can be considered compromised when the owner of the system, a database or a data set no longer has control over the correct functioning and its security.
  • a system, database or even a single record is considered compromised when data could be tampered with and when the owner (or administrator) of the system no longer has control over the correct functioning or correct content, or an attacker controls another reached the goal of the manipulation.
  • Such program errors or software errors or software anomalies are terms from software technology used to describe deviations from a required or desired target state for software system components. These can occur when B. a certain definition of the specification is incorrect or has been implemented incorrectly, and initially leads to an internal error state in the program, which in turn leads to unexpected behavior or results occurring during program execution.
  • the security gate claimed here is a program which is executed by the security ECU, with the security gate having to pass all data from the MC box and/or the BSC box. As soon as it is passed, the corresponding data set to be transmitted is checked for compromises and/or errors.
  • the security gate prevents this data record from being forwarded to the MC box and/or to the BSC box. It is therefore possible that the entire data set is therefore deleted or stored on a data medium in the safety ECU, but is separated from the system and any other data sets. This separation can be software-based. It is therefore also conceivable that the damaged data (compromised and/or containing errors) is then isolated on the security ECU and analyzed in more detail. In any case, damaged data sets are stopped by the security gate and are not used to control any actuators or sensors etc.
  • the system itself can be set up in such a way that the damaged data is extracted from a larger data set, but the rest of the data set is then extracted allowed to pass through the security gate.
  • the security gate removes the entire data set from the data flow.
  • Errors that occur are generally processed systematically in error management. According to the IEEE standard 1044 (classification of software anomalies), each error goes through a so-called classification process, consisting of the four steps of detection Recognition, Analysis, Investigation, Action, and Disposition. In each of these steps, the management activities Recording, Classifying, Identifying Impact are performed.
