The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The simulation test method, device, electronic device and storage medium of the embodiment of the present application are described below with reference to the accompanying drawings. In response to the problems mentioned in the above background technology, the present application provides a simulation test method, in which the CAN port of the virtual gateway is configured based on the test requirements of the assisted driving system and the cockpit domain control, and the closed-loop interaction between the assisted driving system and the cockpit domain control is realized, and the CAN signals of different network segments can be accurately simulated to ensure that the signal transmission between the assisted driving system and the cockpit domain control is accurate, and the signal response between the assisted driving system and the cockpit domain control is tested based on the configured CAN port, which reduces the dependence on the actual vehicle, avoids the high cost and time required for actual vehicle calibration, functional testing and regulatory testing, and does not require the additional purchase of vehicle integrated gateways or dedicated controllers, reducing the construction and maintenance costs of the test platform.

[0030] Before introducing this application, the intelligent driving and cockpit domain control simulation test system involved in this application is described in detail. Figure 1As shown in the figure, it mainly includes RT real-time machine, host computer, optical dark box, virtual test platform, cockpit controller, etc. Among them, RT real-time machine: contains RT processor, various communication boards (CAN / CANFD, serial port, etc.), Ethernet. The lower computer hardware (such as NIPXI) is the hardware core of the test bench. Host computer: runs the scenario model and the veristand simulation test HMI interface. The host computer software (such as VeriStand or CarMaker, ECU-Test) is a software platform for controlling and monitoring the test process. Carmaker scenario model: vehicle dynamics model building software; simulates virtual driving environment, including environmental model, sensor model and actuator model, builds different road conditions, driving scenes, virtual sensor layout, and adds various environmental factors such as different climates, weather, and light; Veristand: configures IO ports and CAN communication data connection relationships; builds virtual instruments, uses the operation interface to monitor and interact with running tasks in real time online; imports vehicle dynamics and environmental variable data; monitors all input and output states of the upper and lower computers in real time and records and analyzes data. ECU-Test integrates test-related software and hardware, generalizes and manages test cases, builds automated test scenarios, and automatically generates test reports. Optical darkroom: plays simulation test scenarios and provides video signals to the ADAS controller for the camera built into the ADAS all-in-one. In the virtual test platform, the RT real-time machine is connected to the simulation test platform through the TCP / IP protocol to configure the parameters of the simulation model. The main function of the simulation test platform is to run the vehicle dynamics model and collect output parameters in the virtual environment. The simulation test results are transmitted to the host computer (Host PC) through CAN communication. The input parameters of the virtual reality simulation software running in the Host PC are converted into the vehicle operation scene environment and displayed on the high-precision display screen. The camera collects the virtual driving scene on the display screen, and sends the control instructions to the virtual test platform after visual processing and decision-making by the all-in-one machine. 5. The cockpit controller communicates with the virtual simulation platform through BD_CAN (equipped with instrument CAN communication segment) and IF_CAN (equipped with central control screen CAN communication segment), so as to achieve the purpose of closed-loop information interaction between the cockpit and the ADAS all-in-one machine. The ADAS all-in-one machine integrated bench is the core component of the entire test system. It is a device that integrates multiple sensors and control units to simulate various vehicle working conditions and environments and provide real-time feedback data. Through the connection with the cockpit instrument, central control screen and cockpit domain controller, it can realize the test of HMI (human-machine interaction) display and cockpit control functions.

[0031] Specifically, Figure 2 A flowchart of a simulation test method provided in an embodiment of the present application.

[0032] like Figure 2As shown, the simulation test method includes the following steps:

[0033] In step S101, the test requirements of the assisted driving system and the cockpit domain control are obtained.

[0034] Among them, the testing requirements include: interaction requirements and signal simulation requirements.

[0035] In step S102, the CAN port of the virtual gateway is configured according to the test requirements.

[0036] It is understandable that the embodiments of the present application can build a virtual gateway based on the simulation test platform software and hardware introduced in the above embodiments to achieve closed-loop interactive communication with the smart cockpit. In the actual implementation process, the embodiments of the present application need to configure the virtual gateway according to the test requirements to ensure that the virtual gateway can effectively support the HIL simulation test of intelligent driving and cockpit domain control, thereby improving the development quality and efficiency of the human-computer interaction function of the ADAS system.

[0037] In one embodiment of the present application, the CAN port of the virtual gateway is configured according to the test requirements, including: configuring CAN1 and CAN2 as CANFD network segments to meet the signal simulation requirements; configuring CAN3 and CAN4 as CAN network segments to meet the interaction requirements. Among them, the baud rates of the CANFD network segment and the CAN network segment are different, and the baud rates of the same network segment are the same.

[0038] Specifically, the embodiment of the present application can utilize the CAN hardware of the host computer Veristand and NIPXI to realize the function of the virtual gateway of the integrated domain control of the whole vehicle. The multi-CAN port function of the lower computer PXI is utilized to realize the CAN hardware configuration of different baud rate segments of the vehicle network.

[0039] 1) Allocate CAN 1 and CAN2 as CANFD segments to meet the signal simulation requirements of the simulation platform ADAS controller and power chassis;

[0040] 2) Allocate CAN3 and CAN4 as CAN segments to meet the signal interaction requirements of the vehicle body and infotainment segments. Different segments are used to achieve signal interaction and switching through the virtual gateway of the host computer software.

[0041] Specifically, in order for ADAS to communicate with the cockpit domain control DMC, it is necessary to simulate the entire vehicle environment (simulation test platform simulation) and transmit relevant signals to DMC through a virtual gateway to achieve information interaction between the intelligent driving ADAS and the DMC intelligent cockpit.

[0042] As shown in Table 1, different network segments on the CAN bus in the embodiment of the present application contain different controller nodes.

[0043] Table 1

[0044] Serial number Controller network segment Network segment description CAN port Baud rate 1 FCM DA_CAN Assisted driving CAN CAN1 CANFD_2M 2 ABS / ESP,EPS CH_CAN Chassis CAN CAN1 CANFD_2M 3 EMS TCU PT_CAN Power CAN CAN1 CANFD_2M 4 FCM DA_CAN ADAS Private CAN CAN2 CANFD_2M 5 IHU IF_CAN Infotainment CAN CAN3 CAN500K 6 ICM BD_CAN Body CAN CAN4 CAN500K

[0045] The baud rates and signals of different network segments are different, and CAN signal interaction can be performed through the CGW central integrated gateway. The DBCs of different network segments are different, and the same signal has large differences in different network segments, and there is signal forwarding across network segments. In the actual implementation process, the embodiment of the present application can use the existing Veristand software to configure the PXI hardware port of the simulation platform. The existing simulation platform has CAN1 and CAN2, both of which are CANFD and baud rate 2M. Therefore, it is necessary to add two CAN channels, namely the body CAN, BD_CAN, with a baud rate of 500k, and the infotainment CAN, IF_CAN, with a baud rate of 500k.

[0046] In the embodiment of the present application, the instrument panel in the cockpit domain controller DMC belongs to BD CAN, and the central control panel belongs to IF CAN. Both CAN 500kBPS, with the same baud rate, belong to different network segments and dbc. ADAS, chassis and power system all belong to the CANFD network segment, with the same baud rate and are allocated in the same network segment. Figure 3 As shown, the virtual gateway has 4 CAN ports for interaction, and signals from different network segments are exchanged with ADAS to achieve signal mapping of different network segments.

[0047] Furthermore, after configuring the CAN port of the virtual gateway according to the test requirements, it includes: configuring a database for different CAN ports.

[0048] It can be understood that the host computer of the embodiment of the present application configures different dbcs for the CAN port and configures the in and out settings of the signal in the dbc. For the ADAS integrated machine, the virtual gateway sets the ADAS signal as input and outputs PT_CAN, CH_CAN, BD_CAN, IF_CAN and other signals to the ADAS. For the cockpit system, the virtual gateway sets the ADAS signal, PT_CAN, CH_CAN, etc. as the cockpit input, and BD_CAN, IF_CAN need to be set according to the actual signal for input and output.

[0049] In addition, in the implementation example of the present application, the main purpose of the simulation is to test the human-computer interaction related functions in ADAS, so it is necessary to sort out the interactive signals of IF_CAN, BD_CAN and DA_CAN, PT_CAN, CH_CAN, and determine the sender and receiver. The simulation platform is an all-in-one machine, and the simulation platform simulates the vehicle environment (ABS / ESP / EPS, EMS, TCU and other vehicle signals) mainly based on CAN FD baud rate, and the human-computer interaction HMI mainly receives signals. The virtual gateway mainly forwards the CAN FD 2M signal from CAN1 to IF_CAN, BD_CAN; maps and interacts the signals between CANFD and CAN 500k, thereby realizing the signal display and interaction of the ADAS all-in-one machine on the instrument and central control screen.

[0050] Furthermore, the embodiment of the present application also needs to set up sending and receiving signals. The receiving signal and sending signal of the virtual gateway are relative. It is equivalent to the transfer controller between the cockpit and the intelligent driving to realize the signal transmission between different network segments.

[0051] 1) BD_CAN is the network segment where the instrument CAN is located

[0052] The virtual gateway receives signals from the instrument, such as ICM_1, ICM_VIN and other signals. The remaining signals are set to send signals, mainly signals from the simulation platform, such as the FCM series signals sent by ADAS (text, lane lines, front vehicles, alarms and other information), and the vehicle ABS, EMS, TCU and other signals simulated by the simulation platform.

[0053] 2)IF_CAN is the central control screen CAN

[0054] It mainly forwards simulation platform signals, such as FCM series signals from ADAS, vehicle ABS, EMS, TCU and other signals simulated by the simulation platform. The most important signals are ADAS soft switch and switch status signals. It receives feedback signals from the central control and does not need to be forwarded to other modules.

[0055] In step S103, a virtual driving environment is built on the simulation platform, and the signal response between the assisted driving system and the cockpit domain control is tested based on the configured CAN port.

[0056] It can be understood that the embodiments of the present application can use simulation software (such as CarMaker, VeriStand, etc.) to build a virtual driving environment. These software can simulate the vehicle's dynamic model, sensor model and actuator model, and provide a realistic virtual driving scene. According to the CAN port parameters configured in the above embodiments, the CAN communication between the simulation platform and the ADAS all-in-one machine and the cockpit controller is ensured to be smooth.

[0057] In one embodiment of the present application, the signal response between the assisted driving system and the cockpit domain control is tested based on the configured CAN port, including: receiving instrument signals and central control signals based on CAN3 and CAN4, and receiving simulation platform CAN signals based on CAN1; parsing and processing the instrument signals, central control signals and CAN signals, and forwarding the processed signal data to the assisted driving system integrated machine, wherein the assisted driving system integrated machine generates control instructions according to the received signals, and sends them to CAN3 and CAN4 to update the display content of the simulated cockpit instruments and the simulated central control screen in the cockpit domain control, thereby realizing a closed-loop interactive test between the assisted driving system and the cockpit domain.

[0058] Specifically, if Figure 4 The specific implementation process shown includes the following steps:

[0059] 1. The CAN ports related to the ADAS integrated machine and the cockpit controller are connected to the CAN ports of the RT lower computer. CAN1 is the simulation platform CANFD_2M, CAN3 is IF_CAN, the baud rate is 500kpbs, and CAN4 is BD_CAN, the baud rate is 500kpbs.

[0060] 2. The ADAS integrated device and cockpit controller are powered on and the power supply remains stable.

[0061] 3. Start the Veristand project, the simulation platform will start, and the scene software Carmaker will be opened. Set the Veristand project to run mode.

[0062] 4. The virtual gateway receives instrument and central control signals through CAN3 and CAN4, and receives simulation platform CAN signals through CAN1.

[0063] 5. The virtual gateway analyzes and processes the received signal, confirms the sending CANID, and sets the sending signal.

[0064] 6. The virtual gateway outputs signals to CAN3, CAN4 and human-computer interaction display platform.

[0065] 7. Load the scenario and test case and run it. At this time, the ADAS integrated machine and the cockpit realize closed-loop interaction.

[0066] 8. A closed-loop interactive environment is established, and the central control screen will display relevant soft switch information.

[0067] The instrument panel displays vehicle information (vehicle speed, gear position, etc.), lane lines, function signs (ACC / AEB / LDW / LDP / SLA, etc.), warnings, and other information based on the scene operation content. This makes the output of ADAS intelligent driving more intuitive. When ADAS runs existing HMI-related test cases, the cockpit instrument panel can display the vehicle, the front vehicle, lane lines, various warnings, and alarm information, and use automated testing to implement lane lines and pop-up windows of various signboards HMI human-computer interaction test functions.

[0068] In summary, it is easier to locate cockpit and intelligent driving problems in human-computer interaction testing, and locate and solve them during the development process, which can not only save a lot of time and human resources, but also minimize the problems and challenges that may be encountered in the actual vehicle verification stage. By implementing closed-loop interaction testing, HMI display problems can be discovered and solved at an early stage, thereby improving the development efficiency and quality of the entire ADAS system.

[0069] According to the simulation test method proposed in the embodiment of the present application, the CAN port of the virtual gateway is configured based on the test requirements of the assisted driving system and the cockpit domain controller, so that the closed-loop interaction between the assisted driving system and the cockpit domain controller is realized, and the CAN signals of different network segments can be accurately simulated to ensure that the signal transmission between the assisted driving system and the cockpit domain controller is accurate, and the signal response between the assisted driving system and the cockpit domain controller is tested based on the configured CAN port, which reduces the dependence on the actual vehicle, avoids the high cost and time required for actual vehicle calibration, functional testing and regulatory testing, and does not require the additional purchase of vehicle integrated gateways or dedicated controllers, thereby reducing the construction and maintenance costs of the test platform.

[0070] Next, the simulation test device proposed according to the embodiment of the present application is described with reference to the accompanying drawings.
