[0037] Figure 2 A block diagram of a relay array system according to an embodiment of the present application is provided; Figure 3 A visual interface diagram of a relay array module according to an embodiment of the present application is provided.

[0038] As Figure 2As shown, the core component of the embodiment of the present application is a relay array module 10, which is installed in the HIL virtual simulation system cabinet. The connection of the wire harness is realized by sending instructions by the HIL host computer 201. The relay array module 10 is composed of four sub-regions, which is powered by the HIL system. The A region (i.e. the first sub-region 100) of the relay array module 10 is the controller 202 connection area, which is distributed with A1, A2... An pins for connecting the measured controller 202 pin wire harness and establishing connection with the controller 202. The wire harness connection with the controller 202 needs to be manually completed in this area. The B region (i.e. the second sub-region 200) of the relay array module 10 is the HIL board card connection area, which is distributed with B1, B2... Bn pins for connecting various HIL board cards on the HIL cabinet 203, such as CAN communication board card, acquisition board card, simulation board card, etc. according to the needs. The bus signal and hard-wire signal output by the controller 202 can be collected, and various input signals required by the controller 202 can be simulated and sent. The wire harness connection with the HIL board card needs to be manually completed in this area. The C region (i.e. the third sub-region 300) of the relay array module 10 is the actuator connection area, which is distributed with C1, C2... Cn pins for connecting the actuator pin wire harness on the actuator rack 204 and establishing connection with the actuator. The function performance of the actuator end can be intuitively felt during the test process. The wire harness connection with the actuator needs to be manually completed in this area. The D region (i.e. the fourth sub-region 400) of the relay array module 10 is the array control area, which is composed of a large number of matrix arranged CAN control relays. The wire harness of the first sub-region 100, the second sub-region 200 and the third sub-region 300 does not need to be manually connected in this area. Through the control instructions sent by the HIL host computer 201, the switching and circulation of signals between the first sub-region 100, the second sub-region 200 and the third sub-region 300 are realized, so as to realize the program control automatic wiring. In addition, as shown in the figure, the HIL cabinet 203 is connected with the controller 202, the actuator rack 204 and the relay array module 10 through the wire harness, and the HIL host computer 201 is connected with the controller 202, the actuator rack 204 and the relay array module 10 through the wire harness. Figure 3As shown, for the HIL host computer 201, the HIL host computer 201 has a visual operation interface, which can be simplified as a graph composed of horizontal and vertical lines, and also represents the fourth sub-region 400 of the relay array module 10, that is, the control logic inside the array controller. Generally, the first sub-region 100, which connects the pins of the output end of the controller 202, is usually connected with the second sub-region 200 of the HIL board card controller 202 to obtain the output state of the controller 202; the first sub-region 100, which connects the pins of the input end of the controller 202, is usually connected with the second sub-region 200 of the HIL board card controller 202 to simulate the input signal required by the controller 202. Due to the strong correlation between the first sub-region 100 and the second sub-region 200, the internal connection state is also defaulted as one-to-one correspondence. The third sub-region 300, for the intelligent driving virtual simulation test, some pins are not needed, and a straight line intersecting with the AC is used to represent. For the visual interface of the host computer 201, only the required intersection needs to be clicked to complete the region connection, and the host computer 201 sends instructions to the fourth sub-region 400, so as to change the signal transmission direction and realize automatic wiring.

[0039] For example, taking the connection of the driving assistance lamp as an example, the function of the driving assistance lamp is that when the controller 202 receives the bus instruction, the controller 202 controls the output pin of the actuator to output high level, so as to light up the driving assistance lamp. Among them, the HIL acquisition board needs to collect the high level output by the actuator, so as to realize the visual display on the host computer 201. The test execution steps of the driving assistance lamp are as follows: Step one: preparation. This step needs to manually complete the wiring connection between the first sub-region 100, the second sub-region 200 and the third sub-region 300. Taking this scene as an example, the light output pin is connected to A1 area, the driving assistance lamp is connected to C2 area, and the HIL acquisition board is connected to B3 area. The next few steps are the specific implementation mode of automatic wiring between the first sub-region 100, the second sub-region 200 and the third sub-region 300.

[0040] Step two: system initialization. This step mainly involves the power-on, self-checking, loading of control programs and configuration files for driving assistance test and other preparation work of the host computer 201, HIL board card, controller 202, relay array module 10 and other devices. In this step, the power-on detection of each hardware device is performed to ensure that the hardware function is normal, and the software program and configuration information for subsequent wiring control and test process management are loaded.

[0041] Step three: the host computer 201 inputs the wiring configuration information. In this embodiment, the host computer 201 visual display interface will appear a dark dot to prompt the user to complete the connection selection by clicking a specific position on the host computer 201 visual display interface. For example, if A1 is clicked on the host computer 201 visual interface, the controller 202 pin selection is completed; if B3 is clicked on the host computer 201 visual interface, the acquisition card selection is completed; if C2 and A1, C2 and A3 are clicked on the host computer 201 visual interface, the actuator pin selection is completed. Finally, click the confirmation button, and the host computer 201 will send the control command to the fourth sub-region 400 of the relay array module 10.

[0042] Step four: the fourth sub-region 400 receives and analyzes the configuration information. The fourth sub-region 400 receives the wiring configuration information sent by the host computer 201 and analyzes it to convert it into an instruction that can accurately control the action of the relay array module 10. The fourth sub-region 400 will perform syntax and logic checks on the input configuration information to ensure its accuracy, and then convert it into a signal form suitable for controlling hardware action.

[0043] Step five: the relay array module 10 performs the wiring action. According to the instruction issued by the fourth sub-region 400, the relay array module 10 acts according to the set logical relationship to realize the connection switching between the virtual simulation control board card, the actuator load end, and the controller 202 end, and completes the wiring operation. The relay array module 10 will accurately change its on-off state according to the instruction to establish the required electrical connection.

[0044] Step six: wiring state feedback and confirmation. After the relay array module 10 completes the wiring action, it feeds back the wiring state information to the fourth sub-region 400, which then uploads the information to the host computer 201. The host computer 201 displays and confirms the feedback wiring state to ensure the accuracy of the wiring operation. The host computer 201 will display the wiring state in an intuitive way, such as through a graphical interface to display the on-off status of each connection line, making it easy for users to check and confirm.

[0045] Therefore, the embodiment can control the wiring through the program, which has repeatability and modifiability, avoiding the repetitive work of traditional manual wiring, greatly improving the efficiency of driving assistance virtual simulation testing, greatly reducing the probability of human error, improving the accuracy and stability of testing, reducing the failure of testing and equipment damage caused by wiring errors, and reducing testing costs. In addition, by controlling the wiring through the program, it is convenient to quickly switch between different test scenarios, improving the flexibility and adaptability of testing, solving the dilemma of traditional manual wiring in driving assistance virtual simulation testing, and better meeting the testing needs of the development of driving assistance systems.

[0046] Further, the embodiment of the present application also provides a driving assistance virtual simulation test program control wiring method, which is realized by a driving assistance virtual simulation test program control wiring system and comprises the following steps: Step one: system initialization. Power on, self-check, load the control program and configuration file for driving assistance test for the host computer 201, the fourth sub-region 400 and the relay array module 10; Step two: the host computer 201 inputs wiring configuration information. The target wiring mode configuration information between the virtual simulation control board card, the actuator load end and the controller 202 end is input through the interactive interface specially designed for driving assistance test of the host computer 201; Step three: the fourth sub-region 400 receives and analyzes the configuration information. The configuration information sent by the host computer 201 is analyzed into instructions for controlling the action of the relay array module 10; Step four: the relay array module 10 executes the wiring action. The connection switching between the virtual simulation control board card, the actuator load end and the controller 202 end is realized according to the instructions issued by the fourth sub-region 400; Step five: wiring state feedback and confirmation. The relay array module 10 feeds back the wiring state to the fourth sub-region 400, which is uploaded to the host computer 201 for display and confirmation.

[0047] Further, the embodiment of the present application also provides a driving assistance virtual simulation test program control wiring system, which is used for realizing the above-mentioned driving assistance virtual simulation test program control wiring method. The system comprises a host computer 201, a fourth sub-region 400, a relay array module 10, a virtual simulation control board card, an actuator load end and a controller 202 end. The host computer 201 is used for receiving the wiring configuration information input by the user for driving assistance test, sending control instructions to the fourth sub-region 400 and receiving and displaying wiring state feedback information; the fourth sub-region 400 is used for receiving the instructions of the host computer 201, analyzing and processing the instructions into signals for controlling the action of the relay array module 10 and receiving and uploading the wiring state information fed back by the relay array module 10; the relay array module 10 is used for realizing the electrical connection switching between the virtual simulation control board card, the actuator load end and the controller 202 end according to the instructions of the fourth sub-region 400, completing the wiring operation and feeding back the wiring state information; the virtual simulation control board card is used as the collection and transmission interface of sensor signals in the driving assistance system and performs data interaction with the actuator load end and the controller 202 end; the actuator load end is used for simulating the load condition of the actuator in the driving assistance system in actual work, receiving test signals and providing corresponding load response; the controller 202 end is used for controlling the driving assistance test process and data processing and cooperates with the virtual simulation control board card and the actuator load end to complete the virtual simulation test.
