Problems solved by technology

[0003] The traditional test method is usually a real vehicle road test. Due to the existence of disturbances such as uneven road surface and wind resistance, it is difficult to quantitatively test the adaptive cruise control system.
Moreover, it is difficult to customize complex traffic road scenarios required for adaptive cruise control system testing in real vehicle road tests, such as: multi-target vehicles frequently enter and exit scenarios, test roads that allow vehicle speeds greater than 120km / h, and bends with different curvatures. Road scenarios, etc., making it impossible to conduct a comprehensive and accurate test of the adaptive cruise control system

Abstract

The embodiment of the invention discloses a test system and method. The system includes an upper computer and a simulation platform. The simulation platform comprises a real-time processor and a control module cluster. The control module cluster comprises a self-adaptive cruise control module and other control modules. The upper computer generates test information and sends the test information tothe other control modules through the real-time processor. The self-adaptive cruise control module acquires relative information between a simulation vehicle and a traffic vehicle, performs self-adaptive cruise control on the simulation vehicle according to the relative information, and sends a self-adaptive cruise control signal to the upper computer, so that the upper computer evaluates the self-adaptive cruise control module and the coordination of the self-adaptive cruise control module and the other control modules. Compared with the prior art, according to the scheme, comprehensive andautomatic testing is carried out on the self-adaptive cruise control module and the coordination of the self-adaptive cruise control module and the other control modules, and the testing accuracy andcomprehensiveness are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automated testing, and in particular to a testing system and method. Background technique [0002] Adaptive Cruise Control (ACC) is an intelligent device used in mid-to-high-end cars in recent years, which can reduce the driver's burden by replacing the driver's acceleration and braking operations. The control effect of the adaptive cruise control system is related to its own performance and the coordination between the system and other systems. Therefore, it is of great significance to conduct a comprehensive test on the adaptive cruise control system. [0003] The traditional test method is usually a real vehicle road test. Due to the existence of disturbances such as uneven road surface and wind resistance, it is difficult to quantitatively test the adaptive cruise control system. Moreover, it is difficult to customize the complex traffic road scenarios required for adaptive cru...
