The camera and GPS locator that USB is connect with master controller, the forward and backward radar, which has been correspondingly connected with, is manually entered key.
Further, the backward radar is BSD radar, and the forward direction radar is FCW radar.
Further, the quantity of the camera and distributing position are adapted with the quantity of radar and distributing position.
A kind of policy validation method of trailer-mounted radar BSD and FCW policy validation system, the specific steps are as follows:
(1) Usage data collection system acquisition data；
(2) collected data are analyzed using data analysis system；
(3) according in step (2) analysis system export wrong report and fail to report information, carry out data readback, compare radar number
According to image data, analyze reason, improve BSD and FCW strategy；
(4) strategy of BSD and FCW in data analysis system is modified, and repeats step (2)；
(5) it updates real steering vectors mileage and statistics is failed to report in wrong report；
(6) step (1) to step (5) is repeated, until BSD and FCW strategy meets final requirement
Further, the collected data of data collection system institute include radar data, vehicle body number in the step (1)
According to, image data, GPS data.
Further, the step of data analysis system concrete analysis data are as follows:
(1) radar data and vehicle body data are formatted, and are input in BSD and FCW algorithm；
(2) strategy for verifying BSD and FCW, exports warning message；
(3) contextual data is generated to image data, GPS data, the field that then handmarking needs BSD or FCW to alarm
Scape；
The scene of handmarking in the warning message and step (3) of BSD and the output of FCW algorithm in step (2) is believed
Information is reported and is failed to report in breath comparison, output by mistake.
The beneficial effects of the present invention are:
The present invention acquires required data by first passing through data collection system, then passes through data analysis system and reads acquisition
The data of system acquisition, and the collected all data of analysis are handled again in computer end, it being capable of fast verification BSD and FCW plan
Slightly, the safety and reliability of BSD and FCW strategy are effectively guaranteed.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:
Fig. 1 is the working principle of the invention schematic diagram.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
It closes attached drawing and the present invention is further described in embodiment.
As shown in Figure 1, a kind of trailer-mounted radar BSD and FCW policy validation system, including data collection system and data analysis
System, the data collection system include Xiang Leida, a FCW after a master controller, a data host computer, two BSD
Forward direction radar, three cameras, a GPS locator, Xiang Leida, one after the distributing position and two BSD of three cameras
It is corresponded before FCW to the distributing position of radar；Xiang Leida and vehicle body pass through before Xiang Leida, a FCW after two BSD
CAN bus is connect with master controller, and three cameras, a GPS locator pass through USB and connect with master controller, in addition, often
One radar has been correspondingly connected with one and has been manually entered key.
When needing to acquire data, the equipment for opening master controller and each connection, the data collection system, which will do it, is adopted
Collect radar data, vehicle body data, image data, GPS data；Wherein radar data and vehicle body data pass through CAN bus by master control
Device acquisition processed, the image data and GPS data of camera shooting are acquired by USB by master controller, and the master controller can
Starting and stopping for control external equipment, ensure that the synchronism of data.
All data are collected during real vehicle road driving, for special scene, can click any
What one radar was correspondingly connected with is manually entered key, corresponds to the data that radar reports in this way while sending a flag data,
It is important or abnormal that the flag data characterizes data, can when data are analyzed selective analysis.
The data analysis system is for reading data collection system data collected and handling it.
A kind of policy validation method of trailer-mounted radar BSD and FCW policy validation system, the specific steps are as follows:
