Definitions
- the invention relates to a method for starting up program packages in vehicles, in particular for starting up a new program package on at least one vehicle computing unit of a vehicle. Furthermore, the invention relates to a system, a vehicle, a program element, a computer-readable medium and a use.
- Vehicle functions are in many cases implemented statically in the vehicle when a vehicle is manufactured and are often difficult to change. In at least some cases, changing a vehicle function requires a workshop visit and/or replacement of the hardware that implements the vehicle function. This can be disruptive in particular if starting a new program package would enable the vehicle function to be improved and/or error correction to be made.
- One aspect relates to a method for starting up a new program package on at least one vehicle computing unit of a vehicle.
- the method has the following steps: loading the program package from a central archive; storing the program package in a vehicle-specific archive; validate the program package in the vehicle-specific archive; determine the vehicle computing unit from a plurality of computing units of the vehicle; providing the validated program package on the vehicle computing unit; and starting the validated program package on the vehicle computing unit, the program package executing a vehicle function.
- the vehicle is, for example, a motor vehicle such as a car, bus or truck, or else a rail vehicle, a ship, an aircraft such as a helicopter or airplane.
- a vehicle computing unit (Vehicle Computing Platform, VCP) is a processor ("general-purpose processor"), a controller, dedicated hardware, e.g. with firmware and/or other types of computing units.
- a program package is a file that can be run, interpreted and/or compiled on at least one of the vehicle computing units.
- the program package can be compressed and/or encrypted.
- the commissioning can include a download and a provision (deployment) of the program package.
- the commissioning of the program package means that at least one of the vehicle computing units can perform one or more vehicle functions.
- the execution of the vehicle functions can begin immediately after the program package has been transferred to the vehicle computing unit (i.e. to a target computing unit), but it can also only be started at a later point in time.
- the new program package can, for example, implement an already existing or a similar vehicle function (“update”), for example as part of an improvement in performance and/or error correction.
- the new program package can, for example, add one or more new vehicle functions (“upgrade”).
- updates can be loaded "automatically", ie for example controlled by a central service staff.
- upgrades may be requested and/or approved by a user—e.g., a driver of the vehicle, a leasing provider, etc.
- At least some vehicle features may belong to both categories, eg a new navigation system.
- the user can decline or defer optional feature updates.
- Mandatory updates can be installed automatically.
- the function can be deployed on a VCP at the time when the function is to be started for the first time.
- the program packages for a vehicle can be supplied by one or more manufacturers. After delivery, the program packages can be stored in a central archive (online repository). The loading of the program package from the central archive can take place via a cable connection and/or wirelessly (wireless). Loading the program package from the central archive can be an optional step, i.e. at least some program packages can already be pre-installed on the vehicle - e.g. during manufacture.
- the wireless transmission of the program package or packages can e.g. via Bluetooth, WLAN (e.g. WLAN 802.11 a/b/g/n or WLAN 802.11 p), ZigBee or WiMax or also cellular radio systems such as GPRS, UMTS, or LTE and/or 5G take place. Alternatively or additionally, the use of other transmission protocols is also possible.
- the vehicle-specific archive may include facilities to validate the program package; this can include verification and/or testing, eg by means of authentication of the program package, regression tests, simulation of interfaces and/or system calls and/or others. These facilities can be available permanently or on demand stand; for example, regression tests can be supplied with the program package.
- the vehicle-specific archive can provide means for simulation and/or emulation.
- Determining the vehicle processing unit (target processing unit) from a plurality of processing units of the vehicle can include an analysis of the target processing unit, the current processor load, the program package and/or other aspects.
- the validated program package is made available (deployment) on the target vehicle computing unit.
- the program package can be started on the vehicle computing unit, so that the program package executes a vehicle function.
- Starting can be immediate, or only after a predetermined event.
- a "fail-operational function” switch to a backup system in the event of an error
- a "fall-back function” switch to a backup system in the event of an error, in at least some cases associated with a downgrading of the original function ) must first be loaded on a backup processor and only activated or started in the event of an error. In this way, for example, a so-called "hot swap" can be implemented in the event of an error.
- the method advantageously provides a framework that simplifies the commissioning of a new program package and also makes it faster and safer. Furthermore, the method can be used for a large number of applications.
- the following list provides some illustrative use cases: • Extended child safety locks for the rear doors can, for example, exclude the operation of the window winders to prevent small children from being trapped.
- An advanced navigation system can, for example, include specifics such as clearance heights, a higher resolution of certain routes and/or predefined colors. This can also be offered as a paid feature, and commissioning and/or delivery can be linked to a payment system.
- a functionally reduced (fall-back) function can be available, which is provided on a target vehicle computing unit and which is activated in the event of an event.
- a dynamic deployment and redeployment of vehicle functions can be supported via a preferably vehicle computing unit. This can make it easier to install new vehicle applications and/or update existing functions without requiring service personnel or a workshop each time. This can also be a basis for new business models, such as "pay per function", "pay per function usage”, etc.
- the method can provide a basis for optimizing the use of resources, e.g. computing and/or network resources, energy consumption , etc., and/or an improvement in the running time of the vehicle processing units, for example because only those processing units that are actually required for a specific application are loaded.
- funds can be made available for a consistent redundancy concept, e.g. for "fail-safe” or "fail-operational" functions.
- validating the program package includes emulating functions that are not executable on an archive processor of the vehicle-specific archive.
- the target vehicle computing unit must be a different processor type or hardware type than the processor ("archive processor") of the vehicle-specific archive.
- the target vehicle processing unit can consist of or have dedicated hardware, a different processor type, different interfaces (eg ioctl) and/or others, so that the program package cannot be run on the archive processor without further ado.
- the hardware dependencies can be significantly reduced by simulating and/or emulating functions.
- loading of the program package is triggered by a request from a user, by a request from an allocator and monitor, and/or by version control.
- the user can, for example, be the driver, a leasing provider, a workshop and/or other people and/or institutions.
- the user can be a monitoring program, for example, which automatically loads a corrected program package when critical errors are detected.
- the user can be a version control to optimize certain functions.
- determining the vehicle computing unit is controlled by a list of criteria that includes:
- a dynamic function assignment is therefore carried out, ie a decision is made about the target vehicle computing unit for the new vehicle function and/or the function update based on an assignment algorithm, taking into account functional dependencies and application restrictions of the function.
- Determining a type of vehicle computing unit can include determining, for example, the hardware of the vehicle computing unit.
- the function can be, for example, the control of window regulators or an infotainment function.
- Determining a computing power of the vehicle computing unit may include, for example, comparing the current power, the maximum power, and/or a history of the power of other processors. This can, for example, lead to a (e.g. temporary) downgrading of the function and/or the selection of an alternative function. It may include analysis of a stay-alive signal. It may include detecting an error and/or marking a faulty vehicle processing unit as unavailable.
- Determining a memory size and/or memory capacity of the vehicle computing unit may relate to throughput and/or latency, for example.
- determining the vehicle computing unit includes selecting an alternative function of the program package.
- the alternative function can be part of the program package, or another function, such as an older function, for example in the event of an error after reinstalling a new function, e.g. just on this vehicle.
- determining the vehicle computing unit and/or providing the validated program package includes storing information about the program package in a vehicle register (Global Function Registry). This means that an overview of the current functions and/or software versions (etc.) can be provided at any time.
- a vehicle register Global Function Registry
- the method further includes stopping and/or uninstalling the vehicle function on another vehicle computing unit; or to stop and optionally uninstall the vehicle function.
- the vehicle function can be a bundle of selected functions.
- the other vehicle computing unit can thus be relieved. This can advantageously be used, for example, in the event of an error and/or in the event of a high load (overload) and/or for an optimization (resource optimization scenario).
- stopping the vehicle function of another vehicle processing unit includes evaluating the criticality of the vehicle function. For example, critical functions can be started on a different processor. For example, non-critical functions can be stopped - at least for a predefined period of time.
- starting the validated program package on the vehicle computing unit is controlled by a start trigger.
- start triggers that only become effective in the event of an overload or error.
- loading the package, saving the package, validating the package, providing the validated package, and/or launching the validated package includes authentication of that action. This can be realized e.g. with cryptographic methods. This advantageously increases security against unauthorized access to vehicle functions.
