Abstract

The invention relates to a simulation test method and a test device, and relates to the technical field of performance testing for a forward collision warning system. The simulation test method is applied to verifying the accuracy of distance recognition of an FCWS (Forward Collision Warning System) prototype in the vehicle driving process, and comprises the steps of extracting pre-collected videodata, and playing the video data; identifying the played video data through the FCWS prototype, simulating the real road scene and generating corresponding driving information, wherein the driving information includes first distance information identified by the FCWS prototype between two vehicles in the simulation test and second distance information between front and back vehicles contained inthe video data; and judging whether the identification of the FCWS prototype for the distance is correct or not according to the driving information. The simulation test method and test device in theembodiment of the invention can complete the verification test for the distance in the current FCWS laboratory test.

Description

technical field [0001] The invention relates to the technical field of performance testing of a forward collision warning system, in particular to a simulation test method and a test device. Background technique [0002] Nowadays, more and more vehicles are equipped with FCWS (Forward Collision Warning Systems), and FCWS is a system that can predict the danger of driving and send an alert to the driver 2.7 seconds before the danger of collision occurs to prevent traffic accidents. Accidents occurred in the product. [0003] FCWS currently uses the camera as the main sensor, detects and tracks the position of the vehicle ahead based on machine vision technology, and judges whether the vehicle is in danger of collision based on the characteristics of the driver, and provides sound, light and vibration warnings to the driver in case of danger; but the current FCWS laboratory During the test, the accuracy of the distance recognition by the FCWS algorithm could not be verified. ...
