Description
Technical field
The present invention relates to safe driving control technology technical field, more particularly to a kind of prison for verifying blind monitoring system
Survey the device and verification method of precision.
Background technology
To lift drive safety, many automobiles have been loaded into blind monitoring system (LWC) at present, after the function is using the right side
The camera shooting vehicle right back image of visor, and be shown on the screen of console, and in order to show in auxiliary judgment screen
The object for the blind spot region shown and the relative distance of vehicle, there are three scores in the screen of blind monitoring system：First object
Line, the second score, the 3rd score, respectively after mark vehicle blind spot region apart from tailstock distance for L1, L2, L3 (3.15m,
11.2m, 24.0m) reference position, by vehicle install blind monitoring system, can significantly cut down the blind of right rear view mirror
Area's scope, by 20 ° of more than 100 ° be promoted to after being loaded into blind monitoring system of script right rear view mirror visual range.Vehicle is offline
Before, need first to carry out LWC on the special post of QA detection lines checking activation, after checking activates successfully, LWC functions can normally make
With, and three scores are shown on screen.Score should meet certain position accuracy demand, verify blind monitoring system
(LWC) process is exactly to examine the positional precision of three scores in screen, that is, verify the display distance of score with it is actual away from
From deviation whether in error allowed band.
First object line, the second score, the 3rd score to the tailstock of vehicle to be verified mark distance respectively L1,
L2, L3, the positional precision of score is verified, it is necessary to first determine the actual bit of projection of the score on verification platform in screen
Put, then measure the projected position on verification platform to actual range L1', L2', L3' of the tailstock of vehicle to be verified, it is actual away from
From with identifying distance versus L1-L1', L2-L2', L3-L3', this deviation is judged whether in error allowed band, so as to verify
The monitoring accuracy of blind monitoring system.The very big working space of this verification process needs, operation difficulty are big.
In order to reduce the working space of measurement, referring to the drawings 3, by the way of blank is put on trailing wheel center line, in vain
Plate will mark the projected position and measurement distance of score by trailing wheel central point and perpendicular to verification platform on verification platform
Mode be changed on blank mark score projected position and measure its height.Drawn by the ratio of similar trianglesIn formula, L is mark distance of the score to the tailstock, measures a and b numerical value first, then passes through blind monitoring
The allowed band value that L is set in the design of system calculates corresponding standard value h allowed band value；Then, reality is measured
Value h', actual value h' and standard value h is contrasted, confirm h' whether in h allowed band value, that is, verify that blind monitoring system is
The no requirement for meeting monitoring accuracy.
Known as described above, referring to the drawings 3, verify that the process key of the monitoring accuracy of blind monitoring system is to determine H points
Position, at present determine H points position method it is as follows：
1st, respectively in the headstock central point of vehicle to be verified, tailstock central point, right rear view mirror camera central point, off hind wheel
Central spot hanging wire mallet, mark in headstock central point B corresponding on verification platform, tailstock central point C, right rear view mirror camera
Heart point A, off hind wheel central point D；
2nd, BC length and BA length are determined by underbody shooting rope；
3rd, it is that radius draws circular arc by center of circle BC of A, is that radius draws circular arc by center of circle BA of C, the intersection point of two circular arcs is J, is used
Rope connects AJ；
4th, make the straight line vertical with AJ lines by tailstock central point C, finally draw corresponding intersection point H.
After determining H points, the distance HA using tape measure right rear view mirror camera central point A to the point H that hangs down；Along off hind wheel
Vertical centerline places the blank perpendicular to verification platform, first makees blank and AJ intersection point F, then the numerical value with tape measure HF.
The method of measurement HA and HF distance value is primarily present following shortcoming at present：
1st, operating procedure is complicated, and time-consuming：Need by underbody shooting rope, draw circular arc, multiple steps such as find intersection, due to
Operating procedure is more, causes that time-consuming and error-prone；
2nd, the accessory used is various, simple and crude：Operating process needs to use scissors, paster, rope, oil pen's aid,
Time-consuming for accessory preparation, inconvenient for use so that probatio inspectionem pecuoarem process operation bothers.
Measurement AH and AF distance difficulty causes to verify that the monitoring accuracy of blind monitoring system is difficult, and being now badly in need of one kind can letter
The method of the monitoring accuracy of single checking blind monitoring system.
