Unmanned testing vehicle platform for automatic driving testing site, and method

Abstract

The invention discloses an unmanned vehicle general platform for automatic driving testing, and a method. The unmanned vehicle general platform comprises a vehicle body shape transformation system which comprises a chassis; a telescopic device is mounted on the chassis, the telescopic device changes the size of a vehicle body through telescopic deformation, and different quick assembly simulationshells are matched to simulate different vehicle models and vehicles; a feedback control system is further mounted on the chassis; the feedback control system comprises a central control device whichis connected to a motor, a braking device and a steering device; and the central control device is further connected to a vehicle sensor measuring unit, and the motion state of a vehicle is obtained through the vehicle sensor measuring unit to decide and control various operation behaviors of the testing vehicle. One testing vehicle can simulate the various vehicles (such as cars, off-road vehicles and trucks), the perceive difficulty of the tested vehicles is increased, and the testing cost is lowered.

Description

technical field [0001] The invention relates to the technical field of automobile safety testing, in particular to an unmanned test vehicle platform and method for an automatic driving test field. Background technique [0002] As "Made in China 2025" proposes to further develop intelligent networked vehicles, intelligent and networked vehicles have become the future development direction. The lack of real and efficient test and evaluation methods has become a bottleneck restricting the development of intelligent connected vehicles. The country has issued regulations that self-driving cars must first pass the test in a closed test field before being tested on the road. At present, self-driving car test fields have been established in various places, but the development of related equipment for self-driving test fields is very backward. Intelligent test equipment mainly relies on imports, and the price is expensive, which seriously limits the development and promotion of my c...

AI Technical Summary

Problems solved by technology

[0003] 1. The mobile test equipment (fake cars, simulated bicycles and simulated pedestrians) used in the current test field generally adopts a fixed shape and color, which will affect the perception results of the tested vehicle during repeated tests, especially for some special-purpose vehicles ( Ambulances, fire trucks, police cars, etc.), generally there is no special test equipment (test car) for simulation, and there is a lack of some important special traffic scene tests

[0004] 2. The mobile test equipment currently used in the autonomous driving test field, including test vehicles, simulated bicycles and simulated pedestrians, generally uses fixed guide rails to control the movement, and is mainly used for traditional collision tests, etc., which cannot simulate complex real traffic scenes. Lack of targeted testing for perception, decision-making, and control of driving cars

[0005] 3. The test equipment currently used in the test field, especially the test vehicles, generally use manual driving, which is highly dangerous, and the test process is not repeatable, and accurate repeated tests cannot be carried out, which is not conducive to targeted self-driving cars. improve training
