With the continuous development of automobile intelligent technology, adaptive cruise system (ACC), as an intelligent driving assistance technology, is gradually being favored by consumers. The ACC system can automatically adjust the speed according to the speed and distance of the vehicle in front to improve driving comfort and safety. In order to ensure the performance and reliability of the ACC system, various automobile manufacturers and R & D institutions usually conduct various tests on the ACC system. This paper will discuss the test content, method and importance of ACC system.

1. Test contents of ACC system

the ACC system is a complex system composed of multiple components and functions. Its test content covers multiple aspects, including but not limited:

• sensor Testing: Including the accuracy, sensitivity and stability tests of sensors such as radars and cameras.
• control algorithm test: Test the response speed and accuracy of the control algorithm of the ACC system in various situations.
• Speed Adjustment Test: Test whether the ACC system can accurately and smoothly adjust the vehicle speed to maintain a safe distance from the vehicle in front.
• Traffic Response Test: Test the ACC system's ability to respond to complex traffic situations, such as performance in congestion, lane changes, etc.
• System Integration Test: Test the coordination and compatibility of the ACC system with other driver assistance systems.

2. Test method of ACC system

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

2.1 real vehicle test

the real vehicle test is a method of installing the ACC system on an actual car and testing and evaluating it under real road conditions. Real vehicle testing can more realistically simulate the performance of the ACC system in the actual driving environment and evaluate its effect on vehicle control and safety.

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 ACC system under different working 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 ACC 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 ACC system testing

as an important intelligent driving assistance technology, the performance and reliability of ACC system directly affect driving safety and comfort. Therefore, it is essential to conduct a comprehensive and rigorous test of the ACC system. Through testing, it can ensure that the ACC system can operate accurately and stably under various conditions, improve driving safety and comfort, and provide drivers with a better driving experience.

Adaptive Cruise Control (ACC) System Test is a key step in ensuring its performance and reliability. Through the real vehicle test, vehicle bench test and software simulation test of the ACC system, the performance of its sensors, control algorithms, speed regulation and traffic response can be comprehensively evaluated, and the quality and stability of the ACC system can be improved. Through continuous improvement and optimization, the ACC system will better provide drivers with a safe and convenient driving experience.
