Automatic emergency braking system (Automatic Emergency Braking, AEB) is an important vehicle safety technology, which can automatically perform emergency braking in the event of a collision risk to reduce the occurrence of collision accidents or reduce the consequences of accidents. In order to ensure the performance and reliability of the AEB system, various automobile manufacturers and R & D institutions usually conduct various tests on the AEB system. This paper will discuss the test content, method and importance of AEB system.

1. Test contents of AEB system

the AEB system is a complex system composed of multiple components and functions, and its testing content covers multiple aspects, including but not limited:

• sensor Testing: Including the accuracy, sensitivity and stability tests of sensors such as radars and cameras.
• Brake system test: Test the coordination and response speed of the AEB system and the vehicle braking system.
• Collision Warning Test: Test whether the AEB system can accurately and timely identify collision hazards and issue warning signals.
• Automatic brake test: Test whether the AEB system can accurately and smoothly perform emergency braking to avoid collision.
• System Integration Test: Test the coordination and compatibility of the AEB system with other vehicle safety systems.

2. Test method of AEB system

in order to ensure the performance and reliability of the AEB system, the following test methods are usually used:

2.1 real vehicle test

real vehicle testing is the method of installing the AEB system on an actual car for testing and evaluation under real road conditions. Real vehicle testing can more realistically simulate the performance of the AEB system in a real driving environment and evaluate its ability to identify and deal with collision hazards.

2.2 vehicle bench test

vehicle bench testing is a method of placing a car on a specially designed test bench for simulation testing. By controlling various parameters and environmental conditions, the performance and characteristics of the AEB system under different operating conditions are evaluated. Vehicle bench testing allows for more precise control of test conditions, providing accurate data support.

2.3 software simulation test

software simulation test is to use computer to simulate the operation of AEB system in different scenarios to evaluate its performance and reliability. Software simulation testing can be carried out in different environments, providing more comprehensive test coverage and reducing test cost and time.

3. The importance of AEB system testing

as an important vehicle safety technology, the performance and reliability of AEB system are directly related to the safety of drivers and pedestrians. Therefore, thorough and rigorous testing of the AEB system is essential. Through testing, it can ensure that the AEB system can quickly and accurately identify the collision risk and take corresponding measures under various conditions, improve the safety performance of the vehicle, and reduce the incidence of traffic accidents.

Testing of Automatic Emergency Braking System (AEB) is a key step in ensuring its performance and reliability. Through the real vehicle test, vehicle bench test and software simulation test of the AEB system, the performance of its sensors, braking system, collision warning and automatic braking can be comprehensively evaluated, and the quality and stability of the AEB system can be improved.
