Description

Validating instruction sequences
Technical Field
The present invention relates to a system for validating a sequence of instructions for controlling a vehicle, the system comprising a client computing device, a cloud and a vehicle, and to a corresponding method.
Background
The driver or user of the vehicle may be provided with services that may be selected and executed through the interface. For example, a display screen inside the vehicle may be used as an interface, and a mobile phone or a tablet computer, etc. may also be used as an interface. Example related services are turned off and on by the smartphone and the vehicle is also started. Examples of related services turn on or off and also start the vehicle via the smartphone. These services can be customized and incorporated into a sequence of instructions (also referred to as a service sequence), which are automatically executed under predefined conditions. Such sequences may be entered in any programming language on any computing device, so long as the computing device has an interface that allows for the entry and modification of the instruction sequences.
A large number of possible instructions that can be selected by the user, in particular by the driver, means that the selected instruction sequence is not necessarily consistent and executable. Furthermore, multiple instruction sequences executed in parallel may interfere with each other and lead to unsafe behavior of the vehicle in traffic. The purpose is therefore to define executable and secure instruction sequences.
Disclosure of Invention
This object is achieved by a system having the features of claim 1 and by a method having the features of claim 7. The dependent claims, the figures and the exemplary embodiments contain further advantageous embodiments of the invention. Embodiments of the invention may be combined in an advantageous manner.
A first aspect of the invention relates to a system for validating a sequence of instructions for controlling a vehicle, the system comprising the vehicle, a client computing device, and a cloud-based architecture for performing a virtual test run setting the sequence of instructions, wherein the computing device is in data communication with the cloud, and the cloud is in data communication with the vehicle.
The system according to the invention is advantageous in that it allows checking the executability of the input instruction sequence. Furthermore, the system allows coordination of different command sequences in order to make driving safer by preventing the command sequences from having unnecessary effects.
A user-side computing device is a computer device operated by a driver or another user of the vehicle. The computer may be, for example, an in-vehicle computer, or a smart phone, laptop, tablet, or other computer, but is not limited to this list.
A cloud-based structure refers to a facility in the cloud. For simplicity, the term "cloud" is used herein as a cloud-based structure. A cloud is a computer network that is available over the internet and provides storage space, processing power, and application software. In particular, the vehicle is a motor vehicle with an electric motor and/or an internal combustion engine.
The user-side computing device of the system preferably comprises at least one first local database comprising available services that can be invoked by the instructions, at least one second local database comprising local constraints, and at least one third local database comprising systems of the vehicle. From the local database, the instruction sequences can also be checked offline by comparison with other instruction sequences.
In the system according to the invention, the data in the local database is preferably based on data in a cloud-based global database.
The user-side computing device is preferably designed to display, via the interface, the selectable instructions for creating the instruction sequences, and to calculate and display additional instructions that can be used in the selected instruction sequences. In this process, the system accesses a local database, i.e., what services can be invoked, what constraints exist, and how the instructions can work with the functions of the vehicle. In addition, the system may compare the new instruction sequence with existing instruction sequences to determine constraints and dangerous or unsafe execution.
In the system, the cloud preferably contains vehicle-based test kits designed to virtually test the sequence of instructions uploaded by the computing device. This virtual test rig is designed based on data relating to the vehicle configuration, which is included in the evaluation of the instructions, constraints and vehicle platform characteristics. The virtual test rig can thus be optimized according to the vehicle configuration. Furthermore, data related to the driving parameters of the vehicle and stored in the cloud may be included in the design of the test rig.
The vehicle preferably comprises at least one controller designed to receive and execute the sequences of instructions for the test in the cloud and also designed to send data about the vehicle and the execution of the sequences of instructions for the virtual test to the cloud.
A second aspect of the invention relates to a method for validating a sequence of instructions for controlling a vehicle by means of a system according to the invention, comprising the following steps:
-providing possible instructions through an interface of a user-side computing device;
-selecting an instruction for creating an instruction sequence, wherein upon selection of an instruction, additional available instructions to be continued in the instruction sequence are immediately investigated;
-transmitting the selected sequence of instructions to the cloud;
-running a virtual test of the sequence of instructions in a test appliance corresponding to the vehicle;
-in case of a successful test, transmitting a sequence of instructions of the test to the vehicle, or transmitting a negative test result to the user-side computing device.
The advantages of the method correspond to the advantages of the system according to the invention.
In the method, the selected instruction sequence is preferably compared to known instruction sequences before transmission to the cloud. A known sequence of instructions is a sequence of instructions that is entered at an earlier point in time and/or stored in a database. If the local test is successful, the user preferably performs a transmission to the cloud. If all tests in the cloud are successfully passed, the sequence of instructions may be used in the vehicle. It is advantageous for this purpose if the information on the vehicle is continuously updated via the internet or a satellite link.
In the method, data relating to parameters of the vehicle is preferably stored in the cloud. In particular, the data relate to driving parameters and to data on the configuration of the vehicle, which data can advantageously be included in the configuration of the test appliance.
In the method, in the event of a test run failure, reports and recommendations regarding improvements are sent from the cloud to the computing device. These may advantageously be included in the reconstruction of the instruction sequence.
Drawings
The invention is explained in more detail with reference to the drawings, in which:
FIG. 1 is a schematic diagram of an embodiment of a system according to the present invention;
fig. 2 is a flow chart of an embodiment of a method according to the present invention.
Detailed Description
In the embodiment shown in fig. 1, the system according to the invention comprises a client computing device 10, computing structures in the cloud 20, and a vehicle 30. The user-side computing device 10 is an on-board computer 11 in a vehicle, which contains an interface in the form of a display screen 12 embodied as a touch screen. Alternatively, it is also possible that the display 12 is not a touch screen, and the instructions are input through a keyboard and a mouse. Examples of alternative client computing devices 10 are stationary computers (PCs), laptops, tablets or smart phones 14, but are not limited to this list. The different user-side computing devices 10 may also be combined with each other, for example by controlling a stationary computer via a smart phone. The entered instruction sequence 13 is displayed on the display 12. In addition, results from one or more test runs of the selected instruction run may be displayed via the interface.
The user may access the functionality 100 of the user-side computing device 10 through the interface. The function 100 comprises providing a service 101 that can be invoked by an instruction, finding a suitable service 102, and checking whether the service 103 can be used.
The user-side computing device 10 further comprises at least one local database arrangement 110. As shown in fig. 1, the local database arrangement 110 contains a plurality of databases. In this case, the first local database 111 is associated with a local service, the second local database 112 is associated with a system of the vehicle 30, and the third local database 113 is associated with possible constraints on the performability of the selected service.
The structures in cloud 20 contain the hardware and software available in the cloud. Cloud 20 contains a global database arrangement 210, which global database arrangement 210, like local database arrangement 110, contains a plurality of databases. In this case, the first global database 211 is associated with local services, the second global database 212 is associated with systems of the vehicle 30, and the third global database 213 is associated with possible constraints on the performability of the selected service. The local database 110 is connected to a global database 210. The local database 110 is here based on data from the global database 210. The user may also work in an offline condition according to the local database 110.
The virtual test appliance 220 is implemented in the cloud 20. The virtual test harness 220 is designed to test a sequence of instructions entered by a user. For this purpose, the test kit 220 is configured according to data from the global database 210 and vehicle parameters of the vehicle 320. The sequence of instructions for the test is provided "on the fly", i.e., for example, over the internet, to the vehicle 30 for use therein.
The vehicle 30 includes a controller 310, the controller 310 being configured to control the sequence of commands entered in the vehicle 30. The controller 310 is divided into a plurality of control units. The first control unit 311 is designed for receiving the instruction sequence tested in the cloud 20 and for using the instruction sequence tested in the cloud 20 in the vehicle 30. The second controller 312 is designed to send the driving parameters of the vehicle 320 to the cloud so that these can be included in the configuration or in the virtual test rig 220. The third controller 313 is designed to send data relating to the vehicle configuration to the cloud 20, which data is stored in the global database 212. Data relating to the vehicle configuration 330 is also included in the configuration of the virtual test appliance 220.
In the method shown in fig. 2 for verifying a sequence of instructions entered by a user, possible instructions are provided through an interface of a computing device in a first step S1. In a second step S2, an instruction for creating an instruction sequence is selected. The instruction sequence is set as follows: if a certain position is reached, the cruise control system is activated, a speed of 50km/h is set and the window on the driver's side is opened 50%. In this process, when an instruction is selected, additional available instructions are immediately selected and displayed, which can continue to be used in the instruction sequence. At the same time, the meaningless or unusable instruction is not displayed and is therefore eliminated from the instruction sequence to be created at an early stage.
In a third step S3, the input sequence of instructions is transmitted to the cloud 20 once the input is completed. This may occur, for example, through a wireless internet connection or a satellite link. In a fourth step S4, the instruction sequence is tested during the test operation of the virtual test appliance 220. In a fifth step S5, the tested command sequence is transmitted to the vehicle 30 and used in the vehicle if the test run has indicated that the command sequence can be used and a report of the effect is sent to the user side computing device 10(S5a) or if the result of the test run opposes the use of the input command sequence, the command sequence is sent back to the user side computing device 10 with a corresponding report (S5 b).
