Test device and method for lane departure warning system

Abstract

The invention relates to a testing device for a driveway deviation alarm system and a method. The device comprises video collecting equipment used for collecting driveway video information, video recording equipment used for receiving the driveway video information from the video collecting equipment and data collecting and synchronous recording equipment used for collecting video information and vehicle real time data; the device further comprises a ticker-timer, and the ticker-timer is used for synchronously marking a timer shaft corresponding to the video information when a tested driveway deviation alarm system alarms normally, alarms falsely and fails to alarm. By means of the testing device for the driveway deviation alarm system and the method, the retrieving and searching of key scene in data processing after substantial vehicle tests are achieved, the data processing efficiency is promoted, and the problem in the prior art that the data processing is time-consuming and labor-consuming is solved.

Description

technical field [0001] The invention relates to a lane departure warning system, in particular to a test device and method for a lane departure warning system. Background technique [0002] The lane departure warning system is generally composed of a head-up display, a front-view camera, a controller and a sensor. The front-view camera is used to identify the marking line of the driving lane and calculate the relative position of the vehicle and the lane. When the driver deviates from the lane unconsciously, the sensor will promptly Collect vehicle data and driver's operating status, and then the controller will send out warnings (sound alarm, image warning, steering wheel vibration or seat vibration, etc.) to remind the driver to pay attention, providing more reaction time for the driver. [0003] Therefore, the lane departure warning system plays an important role in improving vehicle safety, and it also requires an alarm test and performance evaluation before use of this ...

Problems solved by technology

However, in the actual vehicle test process, in order to verify the reliability of the system and the alarm situation, it is necessary to drive a prototype vehicle equipped with a lane departure alarm system for more than 10,000 kilometers. Generally, a huge amount of data will be formed for at least 100 hours. After the completion, it takes a lot of manpower, financial resources and time to process the data. Only by comparing the real situation obtained by the test with the alarm situation of the alarm system can the alarm performance be evaluated.
