Description

Technical Field

[0001] The present invention relates to the technical field of intelligent connected vehicles, and in particular to a method, device, and computer-readable storage medium for testing an intelligent connected vehicle in an electromagnetic compatibility darkroom. Background Art

[0002] As vehicles become increasingly intelligent, features like assisted and autonomous driving are becoming increasingly common. Vehicles rely on a variety of sensors, including cameras, millimeter-wave radar, lidar, and ultrasonic radar, to perceive their external environment, including location, road conditions, lane markings, and objects such as vehicles, obstacles, and people. Simultaneously, the vehicle integrates and processes this perceived data using a robust computing device to form a perception model, providing front-end input for the vehicle's assisted and autonomous driving functions. The incorporation of numerous sensors, controllers, and actuators has transformed the vehicle into a complex and highly sensitive electronic system. While assisted and autonomous driving features are intended to improve safety and enhance travel convenience, they have a complex and potentially dangerous nature. These complex electronic and electrical devices are susceptible to interference from electromagnetic signals. Failures can cause malfunctions in the autonomous driving function or even cause the vehicle to lose control.

[0003] Therefore, EMC immunity testing of intelligent connected functions is necessary to determine whether they function properly under typical electromagnetic interference conditions. To protect electromagnetic order, China prohibits testing by directly releasing interference signals in an open environment. Therefore, most immunity testing is conducted within an EMC chamber. This presents a challenge: these intelligent connected functions rely on sensors to sense the external environment, but an EMC chamber lacks a realistic external environment, such as roads, pedestrians, or vehicles. Therefore, these intelligent connected functions will not function in a standard EMC chamber, making it impossible to test whether they malfunction under interference conditions.

Figure 1 , which is a schematic diagram of the first embodiment of this application. Figure 1 A first embodiment of the present application provides a detailed description of a method 100 for testing an intelligent connected vehicle in an electromagnetic compatibility chamber.

[0027] Step S102: Configuring a scenario test, i.e., applying an electromagnetic interference signal in a predetermined test environment, and configuring a corresponding scenario test for the intelligent connected vehicle, wherein the scenario test includes at least one functional test, generating a single scenario test and / or a combined scenario test;

[0031] Testing Method 100 for Intelligent Connected Vehicles in an EMC Chamber can help automakers and security researchers fully understand the security risks that vehicle information systems may face. It can also rely on sensors in the EMC chamber to jointly perceive the external environment and implement testing and evaluation of intelligent connected vehicles under electromagnetic interference.

[0032] In some embodiments, the single scenario test includes: pedestrian rear-end crossing test, vehicle accompanying and unable to change lanes test, automatic emergency braking scenario test, and adaptive cruise test; the combined scenario test includes at least any two of the following: vehicle accompanying and unable to change lanes test, switching preparation test, automatic emergency braking test, adaptive cruise test, and rear-end crossing test.

Segment FD is a curve transition section, while segment DE is a straight section in the right adjacent lane. Using these segments, HG, FD, and DE can simulate lane-changing scenarios where a vehicle ahead of the vehicle cuts out of its lane. ④ Track segments G-IJ, located in front of the vehicle under test, simulate automatic emergency braking scenarios with pedestrians crossing in front of the vehicle under test. ⑤ Track segment J-IBA, located to the left of the vehicle under test, serves as a connecting segment, enabling the vehicle to return to its home position.
