Problems solved by technology

At present, the principle of gyroscope is generally used to realize the positioning of the test vehicle. The implementation method of this technology is complicated, and the vibration resistance of the gyroscope is relatively poor, so it is not suitable for application in the test vehicle system; in addition, during the test drive process, cumulative errors will occur , in order to eliminate this error, it is necessary to install multiple calibration devices on the side of the driving road, which increases the difficulty of the construction of the examination room

Abstract

The invention relates to a test vehicle driving state detection device of a road driving test and a detection method thereof. The test vehicle driving state detection device of the road driving test comprises a base station and a mobile station, wherein the base station is used for receiving a GPS (Global Positioning System) signal sent by a GPS navigation satellite and generating and broadcasting a differential calibration signal, the mobile station is used for receiving the GPS signal sent by the navigation satellite and receiving the differential calibration signal broadcasted by the base station, a main control computer is arranged in a test vehicle, and the signal output end of the mobile station is connected with the signal input end of the main control computer. The test vehicle driving state detection device has high detection accuracy, simple device structure and low construction cost.

Description

technical field [0001] The invention relates to a driving test detection device, in particular to a detection device and a detection method for detecting the driving state of a driving test vehicle. Background technique [0002] In the actual road driving skills test system that realizes automatic evaluation, accurate positioning of the test vehicle is an important condition for automatic evaluation. At present, the principle of gyroscope is generally used to realize the positioning of the test vehicle. The implementation method of this technology is complicated, and the vibration resistance of the gyroscope is relatively poor, so it is not suitable for application in the test vehicle system; in addition, during the test drive process, cumulative errors will occur , in order to eliminate this error, it is necessary to install multiple calibration devices on the side of the driving road, which increases the difficulty of the construction of the examination room.
