Definitions
- the invention relates in particular to a method for updating and / or expanding the functionality of the sequence control of at least one control unit of a motor vehicle.
- the object of the invention is in particular an improvement of the known method for updating or expanding the functionality of the sequence control of at least one control unit of a motor vehicle.
- the sequence control in the second or in one or more further control devices of the motor vehicle is at all compatible with the sequence control provided for execution by the first control device.
- the compatibility is checked by determining the version of the sequential control system that is currently present in the second or in the further control devices and comparing it with one or more version names or version numbers that are considered to be compatible. Does the existing version of the sequential control in the second or in the other control units as compatible, the updated sequence control or an additional sequence control is made available to the first control unit for execution or is stored therein for execution.
- it can also involve additional data items to expand the functionality of the control unit.
- Such data volumes can be, for example, spatially or temporally limited map data for a navigation system or for the control unit of the navigation system.
- the fact that the compatibility check is carried out in accordance with the invention means that the time-consuming and therefore expensive export of the compatibility information from the vehicle is no longer necessary.
- the compatibility check which is carried out according to the invention in the vehicle can also considerably reduce the possibilities of manipulating the sequence controls or the software of the control units.
- the version of the second control device before changing the sequence control of the first control device in the vehicle, it is checked whether the version of the second control device is at all compatible with the version provided for execution by the first control device. running control is compatible. The compatibility is checked by comparing the current version or version designation of the second or further control devices with one or more version designations or version numbers that are considered to be compatible. If the existing version of the second control device or the further control devices is considered to be compatible, the updated sequence control or an additional sequence control is made available to the first control device for execution or is stored in it for execution.
- the actual states of the versions of the sequential controls in the control units of the motor vehicle and / or the actual states of the versions of the control units of the motor vehicle in the vehicle are determined, preferably periodically, and stored in the vehicle.
- the actual status information required for updating is immediately available. If the current status is determined periodically, e.g. after each parking of the vehicle or during other "rest phases" of the motor vehicle, it is ensured that the current actual conditions are always available.
- the target states of the versions of the sequential controls for the purpose of causing an update or functional expansion in the control units and their sequential controls are transmitted to the vehicle from the outside and stored there.
- the target states and their sequence controls have been signed for checking for falsification and / or via a data medium, such as a DVD, which, for example, additionally has map information for a navigation system in the vehicle, and / or can be transmitted into the vehicle via a wireless interface between the vehicle and the outside world, preferably via a network connection in a vehicle workshop or via a telecommunication connection.
- a data medium such as a DVD
- DVDs with navigation data are located in a DVD drive in the vehicle, which can be accessed by a vehicle data bus. Furthermore, a subscription is generally agreed upon, in which the driver receives DVDs with updated navigation data at certain intervals and exchanges them for a more current DVD in the DVD drive.
- the DVD can have the desired states and their sequence controls, preferably digitally signed, for updating the sequence controls of the control units in the vehicle. It goes without saying that another mobile data carrier can also be used instead of a DVD if this is more expedient.
- a signature check taking place in the vehicle and therefore largely tamper-proof, e.g. As part of a public key process, as described below, it can be ensured that only authorized sequence controls or control devices, in particular those authorized by the vehicle manufacturer, are executed or used in the vehicle.
- the signature is preferably checked using a public key located in the vehicle, which has been stored in the vehicle to prevent it from being changed or falsified.
- the target states of the versions of the sequential controls in the vehicle are compared with the actual states of the versions of the sequential controls and, in the event of a deviation from an update instance provided in the vehicle, to one imported into the vehicle from the outside and there stored measures database is accessed, which specifies the storage measures required for the update and their sequence.
- One embodiment of the invention is such that the first test carried out in the vehicle is carried out using a first database provided in the vehicle, which specifies which version of the sequence control or software in the second control unit must be present in order to be compatible with the version intended for storage in the first control unit or with supplementing the sequence control and / or with the additional data volumes.
- the second test in the vehicle is carried out using a second database provided in the vehicle, which specifies which control unit version the second control unit must have in order to change to the version provided for storage in the first control unit Complement the sequence control and / or to be compatible with the additional data volumes.
- first and second databases can be a single database with corresponding entries.
- a locking device is provided in the vehicle, which prevents the current version of the sequential control system and / or the supplementation of the sequential control system and / or the additional data volumes from being stored in the first control unit if the first and / or second test is negative.
- the locking device arranged according to the invention in the vehicle ensures that incompatible software scopes are not executed and / or used by the control devices of the motor vehicle. It is preferably a software-based locking device that is largely tamper-proof implemented in the vehicle.
- an activation device is provided in the vehicle.
- the more up-to-date version of the sequential control system and / or the supplement to the sequential control system and / or the additional data volumes can only be carried out by the first control unit when it has been enabled for execution by the enabling device, in particular using one enabling code or several enabling codes is or are.
- the unlocking device makes it possible, among other things, to charge additional software, in particular signed, in non-unlocked form Bring the form into the vehicle before it has been ordered or paid for. If the driver orders one or more of these software scopes, the software scopes already in the vehicle can be made available for use immediately after the order or payment process. It is preferably a software-based activation device that is implemented in a largely tamper-proof manner in the vehicle.
- the entries in the first and / or second database have been provided with a digital signature. Before being used, in particular for the first and / or second check, these are checked for authenticity as part of a first signature check provided in the vehicle.
- the more current version of the sequential control system and / or the supplementation of the sequential control system and / or the additional data volumes can only be carried out by the first control unit when the signature verification of the digitally signed entries of the first and / or the second database has shown that the entries or the first and / or second database is or are unadulterated.
- the databases are preferably from the vehicle manufacturer.
- Another embodiment of the invention provides that the more current version of the sequential control system and / or the supplement to the sequential control system and / or the additional data volumes are each digitally signed and before they are executed by the first control unit as part of a second signature check provided in the vehicle be checked for authenticity.
- the more current version of the sequential control system and / or the supplementation of the sequential control system and / or the additional data volumes are only executed by the first control unit can or can, if the second signature check has shown that it is not genuine.
- the software scope preferably comes from the manufacturer of the vehicle.
- the first and / or second signature check carried out in the vehicle is carried out as part of a public key method using a public key that is complementary to the secret key and the public key in the vehicle on at least one Location, preferably at least two locations, can be read out in the vehicle but is secured against falsification.
- a key check is carried out in the vehicle, in which the presence and identity of the public keys stored in the at least two different locations is checked, and the public key is only used in the context of the public key method, if the key check was positive.
- This measure in the vehicle prevents manipulation of the public key and overall ensures that only authorized software scopes, in particular software scopes authorized by the vehicle manufacturer, are executed or used by the control units of the motor vehicle.
- the methods according to the invention also make it possible to provide an advantageous system and an advantageous computer program product for updating and / or expanding the functionality of the sequence control of at least one control unit of a motor vehicle.
