Description

This invention relates to the technical field of vehicle testing, and in particular relates to a method for testing a data storage system, to an apparatus for testing a data storage system and to computer program products for carrying out said method.

As far as intelligent, connected vehicles with high-level driver assistance and/or automated driving functions are concerned, the requirements for their data storage systems are gradually being standardized so that they meet potential management requirements, such as determining accident liability, recreating an accident scenario, etc . At the same time, domain controllers are being used more and more due to their service-oriented, centralized architecture, which is structured according to functions. They not only enable a quicker separation of hardware and software, but also ensure a reduction in computer costs. Many automobile manufacturers integrate the data storage system into the domain controller because, on the one hand, this architecture ensures that the data storage system can share computing resources, storage space, encryption modules, etc. with other applications, and on the other hand, wire harness arrangements can be saved and additional hardware costs can be reduced. However, with this architecture, when testing a production vehicle, environmental scenarios must be set up and/or the vehicle diagnostic system (on-board diagnostics), the vehicle's only physical interface with the outside world, must be used to subject the vehicle to limited readout and/or emulation operations. whereby there are no methods based on a series vehicle to directly operate and/or test a data storage system integrated into the domain controller.

In addition, the configurations of the hardware and software of the automated driving systems and/or the driver assistance systems of the individual automobile manufacturers show very large differences, which makes a standardized, uniform test of the domain controllers extremely difficult. For example, a standardized unified dyno test requires hardware conditions that simulate the configuration required for each vehicle and a signal environment that can simulate and process the vehicle's raw signals. Due to the large differences in hardware and software configuration, it is therefore difficult to develop a test bench test suitable for the development environment of all automobile manufacturers. Likewise, it is extremely difficult to carry out standardized, uniform tests within the context of full-vehicle testing because the operating conditions of the data storage systems of different automobile manufacturers differ. In particular, as far as intelligent, connected vehicles with automated driving functions are concerned, their operating conditions are very closely related to the defined operational design domain or the defined operational design conditions of the automated driving system and/or the driver assistance system, whereby The data storage systems can also only record data when the automated driving system and/or the driver assistance system is activated. However, these are relatively dangerous conditions under which data recording is triggered when the automated driving system and/or driver assistance system is activated, for example when the airbag deploys, when the vehicle yaws at a relatively high rate, when the pedestrian protection system is triggered, etc., so that Whole vehicle test is difficult to implement the aforementioned tests in the aforementioned scenarios, and even if the aforementioned scenarios are run through to a certain extent, it is difficult to ensure the safety of people and the vehicle.

As a result, it is currently a general technical challenge how the data storage systems of intelligent, connected vehicles with automated driving functions from various automobile manufacturers can be standardized and tested uniformly.

The aim of this invention is to provide a method for testing a data storage system, an apparatus for testing a data storage system and computer program products for carrying out said method. The core concept of this invention is the following: standardized emulation of central signals and environments and at the same time partially differentiated structure of the test device based on the system designs of various automobile manufacturers, with the standardized emulation of central signals and environments particularly aimed at being connected to the vehicle event data storage system to place the standing control module in a standard test device; Sending signals to the control module and the data storage system control unit installed in the standard test device and in communication with the vehicle event data storage system to cause said control module and the said data storage system control unit to be placed in the operational standby state and/or which remains there and monitors and collects in real time information on the data that must be recorded as required when the trigger threshold is reached as part of the system design; Speed control and/or acceleration control of the test device such that said control module associated with the vehicle event data storage system triggers data recording, and triggering said control module to send signals relating to collision events to the control unit of said data storage system so as to enable the performance of the trigger data storage by the control unit of said data storage system; after the crash test, retrieving and checking the data stored in the control unit of the data storage system, in particular in the storage unit of the control unit. With the aid of the exemplary embodiments of this invention, the data storage systems of intelligent, connected vehicles with automated driving function of various automobile manufacturers can be standardized and uniform with respect to the triggering mechanisms in collision events using a control module integrated in the test device and connected to the vehicle event data storage system and the control unit of the data storage system be tested.

It should be noted that “operational readiness state” can be understood as follows: In the operational readiness state, the control module 4 connected to the vehicle event data storage system 20 and the control unit 6 of said data storage system 2 are in one for operation (for example, recording data, sending of signals etc.) prepare state and monitor in real time the relevant conditions, including the trigger threshold, process data in real time and prepare for data recording, said recording of data in particular writing data from a dRAM memory to means an NvM storage.

In step S2, the test device 3 is operated to cause said control module 4 to trigger data recording, and said control module 4 to trigger, directly or indirectly, signals and/or protocol data units and/or data frames relating to collision events to the control unit 6 of said data storage system 2 send in order to trigger the control unit 6 of said data storage system 2 to carry out data storage based on the information about the data that must be recorded as required as part of the system design. Here, a “collision event” can be understood to mean a collision or other physical event in which the triggering threshold is reached or exceeded, or any other event in which the restraint device (e.g. an airbag) is irreversibly triggered. A sensor module connected to the vehicle event data storage system 20 is installed on said control module 4 and/or the test device 3, said sensor module connected to the vehicle event data storage system 20 being, for example, a front sensor and/or another monitoring sensor, so that the sensor, trigger and recording functions of a complete vehicle event data storage system 20 are implemented. Based on the needs of differently designed data storage systems, the vehicle position information recorded by said sensor module, for example signals and/or protocol data units and/or data frames relating to the yaw rate of the vehicle, the roll rate of the vehicle, etc., can also be transmitted directly or indirectly via said Control module 4 is sent to the control unit 6 of the data storage system 2, which is information that keeps the control unit 6 of said data storage system 2 in the operational readiness state, as well as information about the data that is required when the trigger threshold is reached as part of the system design must be recorded.

It is to be understood that said control module 4 is configured, for example, in the following manner: replacing the normal connection harness of the control module 4 installed in the vehicle with a modified extended connection module and placing this control module 4 on said test device 3 so that this control device 4 is replaced by it Test device 3 can be controlled. This test device 3 can be installed on or next to the body. In this way, the control module 4 can be tested in a real whole-vehicle hardware environment, in particular while maintaining the connection relationships between the control module 4 and the other components of the vehicle, and using the test device 3, without causing a crash of the real vehicle comes, the control module 4 is triggered.

In the current embodiment of this invention, according to the system design, said control module 4 can directly or indirectly via the third communication module 13 send signals and/or protocol data units and/or data frames related to collision events to the control unit 6 of said data storage system 2. The said third communication module 13 is, for example, a plug connector and/or a communication cable. It should be noted that this communication cable supports LIN channels and/or FlexRay channels and/or CAN channels and/or Ethernet channels, etc., depending on the design and needs of different systems.

In another alternative embodiment of this invention, said control module 4 sends, via the second emulation module 9, signals and/or protocol data units and/or data frames relating to collision events to the control unit 6 of said data storage system 2, said signals and/or protocol data units and/or Data frames can be converted, for example using the second emulation module 9, so that they match the type of input signal and / or the transmission protocol of the control unit 6 of said data storage system 2 and can therefore be read and / or processed.

In another alternative embodiment of this invention, said control module 4 sends signals and/or protocol data units and/or data frames relating to collision events to the control unit 6 of said data storage system via the test device communication module 14 and the test box 7 and via conversion by the second emulation module 9 2. Compared with directly sending signals via the third communication module 13, sending signals via said test device communication module 14 can ensure stable communication during high-speed vibration of the test device 3.

In another alternative embodiment of this invention, said control module 4 sends signals and/or protocol data units and/or data frames related to collision events to the third emulation module 16 via the test device communication module 14 and the test box 7, and the third emulation module 16 converts the received signals and / or protocol data units and / or data frames and transmits them to the control unit 6 of said data storage system 2.

In addition, said control module 4 can also be triggered to send airbag deployment signals and/or protocol data units and/or data frames to said test box 7, these signals and/or protocol data units and/or data frames in the airbag ignition circuit Switch on the vehicle and consequently the explosion of the igniter is triggered, so that the gas generating agent decomposes, said test box 7 comprising, for example, a resistor board and interfaces for monitoring said airbag deployment signals and/or protocol data units and/or data frames , whereby it is qualitatively assessed whether the airbag deployment has been triggered, and said airbag deployment signals and/or protocol data units and/or data frames are sent to the control unit 6 of said data storage system 2 by means of conversion by said second emulation module 9 , which are said signals and/or protocol data units and/or data frames are, for example, flag bits for the airbag status.

It should be noted that said test box 7 includes, for example, communication cable connectors, sensor cable connectors, driving test cable connectors, an airbag emulator 17, a seat belt emulator and/or a power supply unit, wherein said airbag emulator 17 includes the from Control module 4 sent signals relating to collision events or parts thereof are received, so that consequently the received signals can still be forwarded via the communication cable connections, the sensor cable connections and / or the driving test cable connections.

It should be understood that one or more of the aforementioned ways of sending signals and/or protocol data units and/or data frames can be combined in any way according to the system design.

In step S3, the data stored in the control unit 6 of said data storage system 2 is retrieved and a check is made as to whether the control unit 6 of said data storage system 2 has completed the data storage. It should be understood that since the control unit 6 stores the data in the storage unit of the control unit 6, consequently in step S3 the data is retrieved in particular from the storage unit of the control unit 6 and then checked, the retrieval of the data depending on the various System designs can be done differently, for example by using Unified Diagnostic Services and/or by means of network transmission.

It should be noted that the architecture and the solution of this invention can also be implemented without emulation modules, whereby the signals and/or protocol data units and/or data frames to be input relating to said emulation modules can come from real hardware units. For example, the third emulation module 16 can be replaced by a hardware environment formed jointly by several real hardware units, with the hardware units (for example airbag control units) in this hardware environment providing the corresponding signals and/or protocol data units and/or data frames can.

In the following only the differences to the in 1 The exemplary embodiment shown is explained; identical steps will not be described again in order to keep it short.

The said method can also include step S21. In step S21, after operating said test device 3 for a certain period of time (e.g. 2 s) (taking into account factors such as encrypted processing to protect vehicle data, bus communication and latency), it is necessary to use said test device for one to operate for a certain period of time before the power supply is switched off), the power supply unit 10 or (if necessary) one of several power supply units 10 of the control unit 6 of said data storage system 2 is switched off or the connection between the control unit 6 of said data storage system 2 and the power supply unit 10 or one interrupted by several power supply units 10, so that the control unit 6 of said data storage system 2 carries out the data storage when the power supply is switched off or is not normal. It should be understood that said one or more power supply units 10 are power supplies constructed outside the control unit 6 of said data storage system 2. In this case, especially if there are several power supply units, one of the power supply units is only switched off after a certain period of time, in which case the data from the control unit 6 can be tested when the power is switched off or when the power supply is irregular (car manufacturers can use redundant ones with strict requirements and high standards Design power supply units or reserve batteries or supercapacitors can continue to supply the control unit 6 with power, so that this invention therefore does not provide a test method for system designs with already given functional reliability in which all power supply units are switched off in the case of several power supply units 10).

In the following only the differences to the in 1 The exemplary embodiment shown is explained; identical steps will not be described again in order to keep it short.

The method in question can also include steps S20 and S4. After the test device 3 has been operated, the data on the operating state of the said test device 3 is recorded in step S20 using the sensor and recording module 5 and recorded. In step S4, a comparison is made of the data stored in the control unit 6 of said data storage system 2 with the data recorded in the sensor and recording module 5 in order to carry out a reliability check of the data stored in the control unit 6 of said data storage system 2.

4 shows another workflow diagram of the method for testing a data storage system according to another exemplary embodiment of this invention. In the following only the differences to the in 1 The exemplary embodiment shown is explained; identical steps will not be described again in order to keep it short.

The method in question can also include steps S11 and S41. In step S11, the data sent from emulation modules 8, 16 to the control unit 6 of said data storage system 2 is recorded using the monitoring and recording module 15. It should be understood that this step can be performed after sending data in step S1, thereby recording the data for later comparison. It should be noted that since the first emulation module 8 and/or the third emulation module 16 in embodiments of this invention send signals and/or protocol data units and/or data frames to the control unit 6 of said data storage system 2 via the first communication module 11, said first Communication module 11 - which is, for example, a connector and / or a communication cable - can have a signal tap, which serves to ensure that the monitoring and recording module 15 records the data sent by the first emulation module 8 and / or by the third emulation module 16 and records.

In step S41, a comparison is made of the data stored in the control unit 6 of said data storage system 2 with the data recorded in the monitoring and recording module 15 in order to carry out a reliability check of the data stored in the control unit 6 of said data storage system 2.

It should be noted that the monitoring and recording module 15 can also monitor and record the control information sent to the test device 3 and make a comparison between the data recorded on the operating state of said test device 3 with the data stored in the control unit 6 of said data storage system 2 in order to carry out a reliability check of the data stored in the control unit 6 of said data storage system 2.

The aforementioned method steps all belong to test bench tests for a data storage system, which are used to validate the basic functions of the control unit 6 of a data storage system 2, in particular the electronic control unit of a storage system for data from automated driving, as well as extreme operating conditions that are difficult to simulate on an entire vehicle. such as tests to trigger the recording of safety-critical events (collision events, blocked events), tests to verify the accuracy of the data stored for safety-critical events, tests to validate the data storage mechanisms (tests on storage capacity in relation to safety-critical events and tests to overwrite memory , tests for storage capacity in relation to non-safety-critical events), tests for storage during power interruptions, etc. Specifically, in an exemplary embodiment according to this invention, a crash test is carried out on a shaker test stand, with the acceleration of the. using an industrial PC and a drive Shakers are controlled to simulate a collision event so that the triggering environment of the trigger signal is realistically simulated. It should be noted that the standard for tests to validate the data storage mechanisms contains requirements for the control unit 6 of the data storage system 2, in particular the electronic control unit of the storage system for automated driving data, in relation to the storage space and the overwriting mechanisms, for example in relation to Number of storages in the memory of the control unit 6 or, for example, in relation to which data stored in the memory, if the data memory of the control unit 6 is already full, can be overwritten by the data that is then to be written further or which stored data in the memory may not be overwritten , which can be verified by repeatedly triggering the test stand tests and reading out the data in the memory of the control unit 6.

5 shows another workflow diagram of the method for testing a data storage system according to another exemplary embodiment of this invention. In the following only the differences to the in 1 The exemplary embodiment shown is explained; identical steps will not be described again in order to keep it short.

The said method can also include method step S5 of the overall vehicle test sen. In step S5, a defined scenario on a test site corresponding to the conditions is used to trigger the vehicle's reaction to said scenario, so that the control unit 6 of said data storage system 2 is consequently triggered to carry out data storage in relation to the collision risk event. Said overall vehicle test serves to verify whether, for example, the vehicle actually and correctly sends the driving and/or system data to the control unit 6 of the data storage system 2, and whether, after the recording has been triggered by the control unit 6 of the data storage system 2, the Data that must be recorded as required as part of this system design can be stored correctly.

Below, process step S5 of the entire vehicle test is described using specific test scenarios. As an example shows 6 A schematic representation of a complete vehicle test scenario in which a vehicle in front cuts in. The test route is a long straight road with two lanes and the middle lane marking is a white dashed line, with the test vehicle VUT driving at a constant speed in the left lane and the target vehicle VT driving at a constant speed on the right in front of the test vehicle VUT drives. The test vehicle VUT is running normally and has the automated driving system of the entire vehicle, in particular a high level automated driving system (e.g. level L3 or higher), activated. When the test vehicle VUT has reached a certain percentage of the speed limit value and the predicted collision time is after a preset time, for example within 1 s, then the target vehicle VT begins to merge into the left lane and perform the lane change. In this way, the cut-in of the right-front target vehicle VT can be used to trigger an emergency braking of the automated driving system of the test vehicle VUT (for example, the automated driving system requests a braking deceleration of more than 5m/s ² ), so that consequently the control unit 6 of said data storage system 2 is triggered to store the data in relation to the collision risk event.

7 shows a schematic representation of a complete vehicle test scenario in which there is a stationary vehicle in front of the rear moving vehicle. The test route is a long straight road with at least two lanes and the middle lane marking is a white dashed line, with two target vehicles VT in the right lane, with the first target vehicle driving towards the im The second target vehicle, which is at a standstill, approaches and the deviation of the two target vehicles from the center line does not exceed a specified value. The test vehicle VUT is running normally and has activated the system of automated driving of the entire vehicle, in particular a system of automated driving of a high level (for example level L3 or higher), with the test vehicle VUT constantly driving behind the first target vehicle in the right lane. If the predicted collision time of the first target vehicle and the second target vehicle is after a preset time T1, for example within 1 s, the first target vehicle changes lane and pulls out of the right lane and into the left lane. In this way, the emergency pull-out of the front vehicle when it hits the stationary vehicle can be used to trigger emergency braking of the automated driving system of the test vehicle VUT (for example, the automated driving system requires a braking deceleration of more than 5m/s ² on), so that the control unit 6 of the said data storage system 2 is consequently triggered to carry out the data storage in relation to the collision risk event.

In addition, the said method can also include the crash test method steps S50, S51 and S52. In step S50, the test platform for the crash test is equipped in accordance with the test standards and the system design of the vehicle, and causes the control unit of said data storage system 2 to record part of the data before the crash test and to read out said data that has already been recorded.

In step S51, crash tests are carried out on the vehicle according to various test standards. The test content for the crash tests can be selected according to the special features of the different vehicle models and the test standards.

In step S52, the data recorded after the crash tests in the control unit 6 of said data storage system 2 is retrieved and a comparison is made as to whether the data recorded before and after the crash tests match. In this way, it can be verified whether the data recorded in the control unit 6 of the data storage system 2 after the collision is complete and not invalid.
