Abstract

The invention discloses a testing system for automobile control stability. A steering wheel angle sensor, a gyroscope, a speed sensor, and a GPS module are used for obtaining automobile driving parameters; and a data processing unit analyzes the driving parameters. On the basis of comparison of a lateral acceleration value ad and a stable lateral acceleration threshold value a0, stability of automobile driving is determined, thereby realizing real-time detection on the automobile stability. The system has advantages of high precision and fast determination speed. Meanwhile, alarming and corresponding correction can be carried out on unstable situations timely. Besides, the provided testing system with the light weight has the excellent vibration-resistant and impact-resistant performance; and internal independent instruments can be dismounted conveniently. The system can be fixed on a co-driver seat and instrument signal cables can be received conveniently. In addition, the invention also provides a testing method for automobile control stability.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to an automobile handling stability testing system and method. Background technique [0002] The handling stability test needs to use multiple sets of equipment produced by multiple manufacturers to carry out the test. The test personnel need to be familiar with the use of all instruments and set them up correctly. At present, the settings of portable instruments need to be connected and used by installing host computer software on a computer. , It is necessary to install several software produced by multiple manufacturers on the notebook, which is inconvenient to use and maintain, and the security is not high because the notebook is prone to computer viruses. [0003] Usually, the handling stability test needs to be carried out in a professional test field, and the test cost is high. However, the data processing method of the handling stability test is relatively compli...
