Test system and test method suitable for testing vehicle driving performance

Abstract

The invention relates to a test system suitable for testing the vehicle driving performance. The system comprises a GNSS base station, a test device and a test control machine. The GNSS base station is erected on a control point with known coordinates; the test device comprises inertial navigation equipment, a mobile terminal receiver and a radio station; the inertial navigation equipment, the mobile terminal receiver and the radio station are fixedly mounted at the top end of the vehicle body; wherein the inertial navigation equipment is fixedly connected with the mobile terminal receiver through a communication cable, the GNSS base station is in communication connection with the mobile terminal receiver through a radio station to obtain high-precision position data in real time, and thetest control machine is connected with the mobile terminal receiver in a wireless communication mode to receive the data. The test system and method suitable for testing the vehicle driving performance can realize accurate test of vehicle offset parameters and drawing of a vehicle driving track, so that the vehicle performance test system can measure vehicle position information simply and quickly.

Description

technical field [0001] The invention belongs to the command and control technical field of ground vehicles, in particular to a test system and a test method suitable for testing vehicle driving performance. Background technique [0002] Most of the traditional vehicle performance testing methods are based on the water spray method, that is, the water spray method is used to measure the water stain trajectory with a steel ruler. This traditional method has a complex technical structure, the test is greatly affected by the external environment, and the measurement accuracy is poor, and the level of intelligence is low. Based on the shortcomings of traditional methods and the increasing maturity of satellite navigation technology, in recent years, there are more and more schemes to measure vehicle driving performance such as vehicle deviation by using satellite positioning and navigation (GPS) technology. The attitude of the measuring device remains stable, so the accuracy of ...

Problems solved by technology

This traditional method has a complex technical structure, the test is greatly affected by the external environment, and the measurement accuracy is poor, and the level of intelligence is low.

Based on the shortcomings of traditional methods and the increasing maturity of satellite navigation technology, in recent years, there are more and more schemes to measure vehicle driving performance such as vehicle deviation by using satellite positioning and navigation (GPS) technology. The attitude of the measuring device in the middle is kept stable, so the accuracy of the measured value cannot be guaranteed

In this case, how to ensure the attitude stability of the measuring device during the driving of the vehicle has become a restrictive problem
