Vehicle tracking collision safety test system and method

Abstract

The invention relates to a vehicle tracking collision safety test system and method. According to the vehicle tracking collision safety test system and method, all systems of a vehicle are in normal working states in the test process; (2) the self power is used for driving in the whole collision test process; and (3) cruising is carried out according to a preset state and collision is generated. The method comprises the following steps of controlling a tested vehicle in a test scene to automatically drive on a test road according to a preset driving track and preset driving parameters; collecting the real-time driving state information of the automatic driving of the tested vehicle on the test road in real time; performing deviation comparison on the real-time driving state information and the preset driving state information; and if a deviation value between the real-time driving state information and the preset driving state information exceeds a set deviation value range, controlling the tested vehicle to perform steering, acceleration and / or braking actions, so that the tested vehicle continues to collide with a target object located at a set position in the test scene according to the preset driving track and the preset driving parameters.

Description

technical field [0001] The invention relates to the field of automobile testing, in particular to a vehicle tracking collision safety testing system and method. Background technique [0002] The development of vehicle crash safety performance is inseparable from the crash safety test system. At present, the vehicle crash safety test system generally consists of a lighting system, a camera system, a data acquisition system and a vehicle traction system. [0003] The vehicle traction system of the above-mentioned collision safety test system has the following disadvantages: (1) Generally, a motor is required as an additional power source, and special tracks and steel cables are required, which occupy a large area and have very high requirements for the site; (2) the energy provided is limited , the maximum speed of the vehicle being towed is generally around 80km / h; (3) the running route of the vehicle before the collision is limited, generally a straight line; (4) it is diffi...
