Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0036] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied to the field of automotive EMC anti-interference testing technology.

[0037] With the development of smart cars, car functions are becoming more and more complex. In order to ensure that the vehicle's autonomous driving function can operate normally in various electromagnetic environments and will not interfere with other devices or systems, vehicle EMC verification is very necessary.

[0038] According to research, for the EMC verification of the whole vehicle, the anti-interference ability test of the autonomous driving function in the EMC darkroom has the following shortcomings: the traditional EMC anti-interference test is divided according to the function, but there are too many autonomous driving functions to traverse. This will cause the traditional EMC anti-interference test to consume a lot of manpower and time. Therefore, how to efficiently conduct the EMC anti-interference test of the autonomous driving function has become a technical issue that cannot be underestimated.

[0039] Based on this, an embodiment of the present application provides an EMC anti-interference test method for an autonomous driving function, which saves test time, improves the efficiency of the EMC anti-interference test for the autonomous driving function, and reduces the investment in experimental equipment and manpower.

[0040] See also Figure 1 , Figure 1 The flowchart of an EMC anti-interference test method for an autonomous driving function provided in an embodiment of the present application is used to test the anti-interference capability of the autonomous driving function of a vehicle set in an EMC darkroom, such as Figure 1 As shown in, the EMC anti-interference test method provided in the embodiment of the present application includes:

[0041] S101, determining multiple hardware devices involved in the autonomous driving function of the vehicle to be tested.

[0042] For the above step S101, in the specific implementation, for the vehicle to be tested, multiple hardware devices involved in the automatic driving function of the vehicle to be tested are determined. Specifically, firstly, the vehicle to be tested is selected, and the automatic driving hardware architecture diagram of the vehicle to be tested is determined to determine the automatic driving architecture, and then the multiple hardware devices involved in the automatic driving function are determined.

[0043] Specifically, according to the embodiments provided in the present application, the multiple hardware devices involved in the autonomous driving function include but are not limited to lidar, millimeter-wave radar, camera, vehicle-mounted inertial measurement unit, navigation system, steering system, braking system and throttle system.

[0044] Here, in autonomous driving technology, sensors are used to sense the environment around the vehicle and provide necessary data input. LiDAR: Creates a 3D point cloud map of the surrounding environment by emitting laser beams and measuring the reflection time. Provides high-precision distance and shape information. Camera: Used to capture visual information and identify traffic signs, lane lines, pedestrians and other vehicles. Multiple cameras are usually used to cover different perspectives. Millimeter wave radar: Detects the distance of objects by emitting radio waves and measuring the reflection time. On-board inertial measurement unit: Used to measure the acceleration and angular velocity of the vehicle to help determine the vehicle's motion state. Navigation system: Such as GPS, used to determine the location of the vehicle, usually used in conjunction with the on-board inertial measurement unit to improve positioning accuracy. Steering system: Used to control the steering of the vehicle. Braking system: Used to control the braking of the vehicle. Throttle system: Used to control the acceleration of the vehicle.

[0045] S102: In a specific test scenario, when the EMC interference immunity test of the autonomous driving function of the vehicle to be tested begins, the test data generated by each hardware device is obtained, and based on the test data generated by each hardware device and the original data corresponding to each hardware device, it is determined whether the autonomous driving function of the vehicle to be tested is normal.

[0046] Here, the specific test scenario refers to the experimental environment built in the EMC darkroom when the EMC immunity test is performed on the vehicle to be tested. Here, as an example, the specific test scenario can be a scenario where an obstacle appears when the vehicle to be tested is driving on the road, and this application does not make specific limitations on this. The raw data represents the data collected by the hardware device under the specific test scenario when the autonomous driving function of the vehicle to be tested is normal.

[0047] For the above step S102, in the specific implementation, before the EMC anti-interference test of the automatic driving function of the vehicle to be tested begins, it is necessary to obtain the original data collected by each hardware device in a specific test scenario when the automatic driving function of the vehicle to be tested is normal. Continuing the above embodiment, when the specific test scenario is a scene in which an obstacle vehicle appears 2 meters in front of the vehicle to be tested when the vehicle to be tested is driving on the road, when the hardware device is a laser radar, the original data is the point cloud information of the obstacle vehicle; when the hardware device is a millimeter wave radar, the original data is the distance between the vehicle to be tested and the obstacle vehicle, that is, 2 meters; when the hardware device is a camera, the original data is the image corresponding to the obstacle vehicle. At the beginning of the test, the vehicle to be tested is placed in an EMC darkroom, and the EMC anti-interference test is performed on the vehicle to be tested in a specific test scenario. When the EMC anti-interference test of the automatic driving function of the vehicle to be tested begins, the test data generated by each hardware device on the vehicle to be tested is obtained, and based on the test data generated by each hardware device and the original data corresponding to each hardware device, it is determined whether the automatic driving function of the vehicle to be tested is normal. In this way, a test environment is set up in the vehicle EMC laboratory, the autonomous driving components of the vehicle to be tested are run, the vehicle software is updated for monitoring, the corresponding underlying hardware / software of the vehicle to be tested is run and testing is carried out. The EMC interference immunity test of the autonomous driving function of the vehicle to be tested can be performed by monitoring the test data collected by each hardware device and the original data corresponding to each hardware device.

[0048] As an optional embodiment, after determining the multiple hardware devices involved in the automatic driving function of the vehicle to be tested, the EMC anti-interference test method further includes:

[0049] For each hardware device, determine the data transmission mode corresponding to the hardware device and the target data type that the hardware device needs to output in the specific test scenario.

[0050] Here, the data transmission mode refers to the way in which the hardware device transmits the data after collecting the test data. The target data type refers to the type of data that the hardware device needs to collect in a specific test scenario.

[0051] For the above steps, during the specific implementation, for each hardware device, determine the data transmission method corresponding to the hardware device, as well as the target data type that the hardware device needs to output in a specific test scenario. Here, as an example, when the specific test scenario is a scenario where an obstacle appears when the vehicle to be tested is driving on the road, the target data type output by the lidar can be pre-set as point cloud information, and the point cloud information is output via OBD Ethernet; the target data type output by the millimeter-wave radar is obstacle distance information, and the obstacle distance information is output via OBD Ethernet. The target data type output by the camera is obstacle image information, and the obstacle image information is output via OBD Ethernet. Here, different hardware devices can set different data transmission methods according to needs, and this application does not make specific limitations on this.

[0052] Specifically, with respect to the above step S102, the acquiring of the test data generated by each hardware device, and judging whether the automatic driving function of the vehicle to be tested is normal based on the test data generated by each hardware device and the original data corresponding to each hardware device, include:

[0053] Step 1021: For each hardware device, the test data generated by the hardware device during the EMC anti-interference test is obtained through the data transmission method corresponding to the hardware device.

[0054] Here, the data type of the test data generated by the hardware device is the target data type that the hardware device needs to output in a specific test scenario.

[0055] Regarding the above step 1021, during specific implementation, for each hardware device, the test data generated by the hardware device during the EMC anti-interference test is obtained through the data transmission method corresponding to the hardware device.

[0056] Step 1022: Determine whether the automatic driving function of the vehicle to be tested is normal based on the test data corresponding to the hardware device and the original data corresponding to the hardware device.

[0057] Regarding the above step 1022, during the specific implementation, it is determined whether the automatic driving function of the vehicle to be tested is normal based on the test data corresponding to the hardware device and the original data corresponding to the hardware device.

[0058] Specifically, with respect to the above step 1022, judging whether the automatic driving function of the vehicle to be tested is normal based on the test data and the original data corresponding to the hardware device includes:

[0059] Determine whether the test data corresponding to the hardware device and the original data corresponding to the hardware device are the same; if so, it is considered that the automatic driving function of the vehicle to be tested is normal.

[0060] Regarding the above steps, during the specific implementation, for each hardware device, determine whether the test data generated by the hardware device during the EMC anti-interference test is the same as the original data corresponding to the hardware device; if so, it is considered that the automatic driving function of the vehicle to be tested is normal, that is, the automatic driving function of the vehicle to be tested is not affected by the electromagnetic environment.

[0061] Here, continuing with the above embodiment, when the specific test scenario is a scenario where an obstacle vehicle appears 2 meters in front of the vehicle to be tested when the vehicle to be tested is driving on the road, if the hardware device is a millimeter wave radar, the test data collected by the millimeter wave radar in the specific test scenario is an obstacle distance of 1 meter, and the original data corresponding to the millimeter wave radar in the specific test scenario is 2 meters, the test data is not the same as the original data, then it can be judged that the automatic driving function of the vehicle to be tested is affected by the electromagnetic environment. If the hardware device is a laser radar, the obstacle point cloud information collected by the laser radar in the specific test scenario is obtained, and the obstacle point cloud information is compared with the point cloud information of the obstacle vehicle. If they are not the same, then it can be judged that the automatic driving function of the vehicle to be tested is affected by the electromagnetic environment. In this way, if the test data corresponding to each hardware device is the same as the original data, it is considered that the automatic driving function of the vehicle to be tested is normal.

[0062] The EMC anti-interference test method for the autonomous driving function provided in the embodiment of the present application is used to test the anti-interference capability of the autonomous driving function of a vehicle set in an EMC darkroom. First, multiple hardware devices involved in the autonomous driving function of the vehicle to be tested are determined; then, in a specific test scenario, when the EMC anti-interference test of the autonomous driving function of the vehicle to be tested starts, the test data generated by each hardware device is obtained, and based on the test data generated by each hardware device and the original data corresponding to each hardware device, it is judged whether the autonomous driving function of the vehicle to be tested is normal.

[0063] This application decomposes the EMC anti-interference test from the monitoring of function realization to the monitoring of the underlying hardware performance, divides multiple hardware devices according to the hardware architecture of autonomous driving, and outputs the test data collected by each hardware device through the bus in the EMC anti-interference test of the autonomous driving function, and diagnoses the working status of related components by monitoring the test data collected by the hardware device and the original data corresponding to the hardware device, and then tests the autonomous driving function of the whole vehicle, which not only saves test time and improves the efficiency of the EMC anti-interference test of the autonomous driving function, but also reduces the investment in experimental equipment and manpower.
