Testing equipment and method for testing FCW, AEBS and RCWS

Abstract

The invention discloses testing equipment and method for testing FCW, AEBS and RCWS, and relates to the technical field of vehicle performance testing, the testing equipment comprises a first guide rail, and the first guide rail comprises a first fixed rail and a moving rail. The road motion of the target vehicle in the test is converted into the track motion, the transverse motion of the target vehicle is eliminated, the transverse deviation is reduced by 50%, the two objects originally moving respectively in the test are converted into the relative motion, meanwhile, the longitudinal deviation is reduced by 50%, the test accuracy is greatly improved, and the test efficiency is improved. FCW / AEBS testing consistency and testing accuracy are improved, and the problem that conventional testing equipment and methods cannot test the working conditions of early warning / emergency braking of too small time headway of FCW and AEBS is solved; meanwhile, the speed and distance of relative movement can be accurately controlled through the system, and the problems that in current testing, the relative distance and respective speed of the tested vehicle and the target vehicle are difficult to control, the accuracy is low, the number of effective testing times is small, and the testing efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle performance testing, in particular to a testing equipment and method for testing FCW, AEBS and RCWS. Background technique [0002] Forward Collision Warning System (FCW) is a system that automatically detects target vehicles or obstacles through sensors such as radar and cameras, detects potential forward collision hazards, and sends out warning signals to remind drivers to reduce collision risks. The core indicators of the test are Early Warning Distance to Collision Time (TTC) (TTC refers to the time required for the vehicle under test to collide with the target obstacle at time t); Vehicle Automatic Emergency Braking System (AEBS) automatically detects the target vehicle or vehicle through sensors such as radar and camera. Obstacles, detect potential danger of forward collision, send out warning signals to remind the driver, and activate the braking system of the vehicle to avoid or mitigate co...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a test equipment and method for testing FCW, AEBS and RCWS, one purpose of which is to have the function of reducing the lateral deviation and longitudinal deviation, and solve the problem that the lateral deviation and longitudinal deviation have great influence on the test; Another purpose is to solve the inaccurate and difficult-to-control problems of important test indicators such as the distance between two vehicles and vehicle speed during the test, so as to achieve the effect of dynamic and precise control of indicators such as vehicle distance and vehicle speed for users; the last one The purpose of the project is to solve the problem that the current test methods cannot accurately control the coordinated motion state of the vehicle under test and the target vehicle, resulting in the inability to test the condition that the distance between the vehicle in front of FCW or AEBS is too close
