Description
Technical field
The present invention relates to driveway deviation alarming system, the test device of specifically a kind of driveway deviation alarming system and side
Method.
Background technology
Driveway deviation alarming system it is general main by HUD, forward sight camera, controller and sensor group into,
The markings of traveling lane are recognized using forward sight camera, the relative position of vehicle and track is calculated, when driver is unconscious partially
During from track, sensor can in time collect the mode of operation of vehicle data and driver, be given a warning (sound by controller afterwards
Alarm, image warning, vibration of steering wheel or seat vibrations etc.) remind driver to note, when providing more reactions for driver
Between.
Therefore, driveway deviation alarming system important role on vehicle safety is improved, also causes that such product exists
Need to carry out ann test and Performance Evaluation before use, to check whether product reaches qualified alarm criteria.Qualified car
Road deviation warning product must reach low rate of failing to report, and wrong report as few as possible.
At present, the alarm performance evaluation mode to driveway deviation alarming system not yet forms unified understanding, major researchs
There are the evaluation method of oneself in mechanism and manufacturer.Some use driving simulators, advantage must when being and can simulate real train test
The dangerous situation that must be accepted the risk, can more test out the potential ability of product, and the acquisition of various parameters is relatively easy to, but platform sets
Meter work complexity, the more difficult foundation of simulated environment, build it is relatively costly.Thus, major part is more likely to real steering vectors, and advantage is
Most can truly reflect the operating mode of driveway deviation alarming system, driver can also take seriously, and test result really degree is high.
But during real steering vectors, in order to the reliability and alarm condition of checking system are, it is necessary to be equipped with deviation alarm system
The sample car of system travels longer than 10,000 kilometers, will generally form at least huge data volume of 100 hours, is so testing
Need to spend substantial amounts of manpower, financial resources and time to carry out data processing after, the live and alarm for comparing test acquisition is
The alarm condition of system, can evaluate its alarm performance.
The content of the invention
It is an object of the invention to provide the test device and method of a kind of driveway deviation alarming system, it is easy in data
The lookup of key scenes in processing procedure, lifts data-handling efficiency.

Information, Normal Alarm, the number of times made a false report and fail to report in statistics key scenes.
E, test report：Reference standard ISO17361 2007（E）《Intelligent transportation system driveway deviation alarming system performance
It is required that and detection method》, to be tested driveway deviation alarming system alarm performance be analyzed, generation report.
The processing speed of rear data is completed to further speed up, when tester presses tapper 4, timely contingency table
Note, the settings button one of tapper 4 to button 6 41 ~ 46 6 button, as shown in figure 3, six physics ID of correspondence.Testing process is such as
Shown in Fig. 4, when observing that vehicle left side deviates, driveway deviation alarming system Normal Alarm then presses button 1；When observe
Vehicle without departing from when, driveway deviation alarming system occur left side alarm (false), then press button 2 42；When it was observed that vehicle left side
During deviation, driveway deviation alarming system is not alarmed (fail to report), then press button 3 43；When observing that vehicle right side deviates, track
Departure warning system Normal Alarm, then press button 4 44；When observe vehicle without departing from when, driveway deviation alarming system occurs right
Side is alarmed (false), then press button 5 45；When observing that vehicle right side deviates, driveway deviation alarming system is not alarmed and (is leaked
Report), then press button 6 46.In later data treatment, statistics left side is deviateed Normal Alarm, makes a false report, fails to report and right side is inclined respectively
From Normal Alarm, make a false report, fail to report when, only need to directly retrieve various key scenes gets cumulative frequency ready.Later stage classification can be omitted
The step of statistics, further lift data-handling efficiency.
