Vehicle emergency avoidance real vehicle test system and method

Abstract

The invention belongs to the field of automobile electrical testing, and relates to a high-precision positioning vehicle emergency avoidance real vehicle testing system and method. Comprising a GPS and RTK antenna module, a data acquisition and processing module, a gyroscope, an automobile CAN box tool and an upper computer. The GPS and RTK antenna module obtains high-precision position information of the test vehicle by using a GPS antenna in combination with an RTK differential positioning technology; the gyroscope is used for obtaining motion state information of the test vehicle; the data acquisition and processing module is used for acquiring test vehicle position information and motion state information; the automobile CAN box tool is used for reading the CAN signal data converted by the data acquisition and processing module and the required test data on the test vehicle bus, and sending the CAN signal data and the required test data to the upper computer to obtain the test data in the emergency avoidance process; complete and accurate test data in the emergency avoidance process can be obtained in a real road environment, the analysis workload of test personnel on the test data is reduced, the test efficiency is improved, and the test quality of the emergency avoidance function is effectively improved.

Description

technical field [0001] The invention relates to the field of automotive electrical testing, in particular to a real-vehicle testing system and method for emergency avoidance of high-precision positioning vehicles. Background technique [0002] Nowadays, the configuration of different intelligent networking functions is the core differentiated competition direction created by many automobile manufacturers, and the degree of intelligence of automobiles is getting higher and higher, which has also received increasing expectations and attention from automobile consumers. Among them, emergency obstacle avoidance, as an important part of the ADAS function, is of great significance for improving the driver's road safety and reducing the occurrence of traffic accidents. At the same time, because different automobile manufacturers will choose different suppliers and other combination solutions for the same function in different models and different configurations, this also brings ch...
