Test and Analysis on Distance Measurement Accuracy of Commercial Vehicle Forward Collision Warning System

The distance measurement accuracy is directly related to the safety margin of forward collision warning system (FCWS) warning time, which affects the safety of vehicles and pedestrians. Distance measurement accuracy of a commercial vehicle equipped with different FCWS sensing schemes was tested and analyzed according to relevant regulations and standards on the basic of the analysis of the distance measurement principle of FCWS sensor scheme. The test results show that the distance measurement accuracy of millimeter wave radar and camera information fusion has the preferable performance. Besides, we pointed out some problems existing in the test and evaluation of distance measurement accuracy for commercial vehicle FCWS and put forward some feasible suggestions.
