Introduction

This procedure is based on JJG 745-2002, with reference to JJF1002-2010 "National Metrological Verification Regulation Write the rules "to revise, and JJG 745-2002" motor vehicle headlamp detector "compared to, in addition to JJF1002-2010 "National Metrological Verification Rules for the preparation of rules" made by the chapter composition and format changes, the main The technical changes are as follows. --- Added the English interpretation of the term (see 3); - revised the overview of the automatic headlamp instrument (see 4); - in the measurement performance requirements, the merger of the first test and follow-up test, the use of inspection on the light intensity and optical axis deviation Shift angle (angle) of the indication error requirements; cancel the near-light light and dark cut-off angle offset (angle) of the indication error Request; cancel the front light instrument height than the measurement range and height than the indication error requirements; the luminous intensity indication error in the Zero angle and other angles within the measurement range are combined (see 5); --- In the general technical requirements, with the near-light detection function of the headlamp instrument, an increase of near-light function characteristics Request (see 6.3); - in the test conditions, revised and improved the main measurement of the standard equipment requirements (see 7.1.1); --- In the verification project, according to the measurement performance requirements and general technical requirements of the adjustment, the test items made a phase Should be amended (see 7.2); --- In the test method, according to the luminous intensity of the instrument was measured measuring range, the test point from the original "8kcd, 10kcd, 15kcd, 20kcd, 30kcd", revised as. "8kcd, 15kcd, 20kcd, 25kcd, 30kcd, 40kcd "(light intensity measurement of the upper limit of 60kcd) and" 8kcd, 15kcd, 20kcd, 30kcd, 40kcd, 60kcd (light intensity measurement of the upper limit of 120kcd); the optical axis angle offset value (angle) The calibration point is corrected by the magnitude of the angle and offset values; the off-angle of the near-light cut-off line is canceled (See 7.3); the method of verification of the height ratio of the automatic headlamp instrument is eliminated; --- modified the test record recommended format (see Appendix A); increased the certificate (inside page) format, verification (See Appendix B); an increase in the uncertainty of the test results (see Appendix C). Prerequisites of this Code Release. --- JJG 745-2002. Verification procedure of vehicle headlamp detector

1 Scope

This procedure applies to the first test of the motor vehicle headlamp detector (hereinafter referred to as the headlamp instrument), the subsequent verification and Check in use.

2 reference file

This procedure refers to the following documents. Safety technical conditions for motor vehicle operation GB 7258 GB/T 13306 signs GB 21861 Motor vehicle safety technical inspection items and methods For dated references, only the dated edition applies to this rule; references that are not dated , The latest version (including all amendments) applies to this procedure.

3 terms and units of measurement

3.1 high beam center centeroffarlight The current light is illuminated at a distance of 10 m from the headlamp (screen origin and headlamp base Quasi-center has been aligned), if the distance from the origin on the horizontal axis of the screen coordinate system is left 52.4cm and right 52.4cm two equal illumination, and the coordinate system on the vertical axis from the origin of 17.5cm and 17.5cm on the two Where the illumination is also equal, the position of the screen coordinate origin is the center of the far beam. 3.2 headlamp reference center height referencecenterheightofheadlamp The distance between the reference center and the ground, in meters (m). 3.3 detection distance detectiondistance The distance from the headlamp reference center to the headlamps is the distance from the mirror of the light box, in meters (m). 3.4 optical angle angle opticaxialangle The angle between the headlamps of the headlamps and the horizontal plane and the vertical axis of the headlamps, (Minute('). 3.5 optical axis offset value (angle) offsetofopticalaxis The headlamp is illuminated at a distance of 10 m on the screen with a high beam center, near beam of light beam cut The offset distance (angle) of the screen origin, in cm/dam (°). 3.6 Optical axis offset value (angle) Indication interval difference absolutedifferencebetweenthemaximumandmini- mumindicationerrorsoftheoffsetofopticalaxis In the case of calibrator light intensity and optical axis offset value (angle) unchanged, automatic headlamp instrument from the upper and lower, Left and right tracking measurement, measured optical axis offset value (angle) maximum indication error and the difference between the minimum indication error On the value.
