27、ign. Copyright SAE International Provided by IHS under license with SAE Not for ResaleNo reproduction or networking permitted without license from IHS -,- SAE J914 Revised JUL2003 RationaleThe changes are as follows: Simplistic diagrams of both right adjacent lane and left adjacent lane to the vehic
28、le equipped with the side turn signals are presented. The dimensions are approximate but are based on available vehicles. The sketch of the plan view shows the vehicles centered in 12 feet wide lanes (3658 mm or 144 inches). The cross-hatched areas are the boundaries of the photometric pattern. In t
29、he right adjacent lane the following driver will detect the photometrically required signal at a distance of 6922 mm (272.5 in or 23 ft) away from the side turn signal or 6502 mm (256 in or 21 ft) in the direction of travel. NOTEThe signal will be detected earlier but the intensity may be unreliable
30、 since it is not defined. At this position it is truly an auxiliary or supplemental signal since the driver is still in view of the rear turn signal of the leading vehicle. The right adjacent lane elevation view shows that, at the 70 degree angle, a line drawn from the 1650 mm height at 10 degrees d
31、own crosses the line drawn from the original 1220 mm mounting height at 5 degrees down. At any distance beyond this intersection the higher mounted signal can be seen at a LOWER eye level. Since the drivers position is at approximately 272 in away from the signal and the intersection occurs at 190 i
32、nches the driver (of the following vehicle) could easily detect the signal from the higher mounted turn signal. As the following vehicle overtakes the lead vehicle the drivers eye line and the point of intersection converge at approximately the 63 degree angle. Beyond this point the following driver
33、s eye will no longer be within the controlled photometric zone (although he/she may still see the signal). As the following vehicle proceeds through the photometric controlled zone the drivers eye location line intersects the 30 degree photometric line at 108 inches from the side turn signal. At thi
34、s location the 5 degree downward line in 38.5 inches above the pavement and the 10 degree downward line is 46 inches above the pavement. Therefore, neither mounting height catches the eye line of the 5th percentile driver in a sports car. To make the new mounting height, 1650 mm, equivalent in perfo
35、rmance to the previous mounting height, 1220 mm, the downward angle must be at least 13.8 degrees. The photometric downward angle has been changed to 15 degrees from 10 degrees. Since the existing standard does not meet this objective (the eye of the 5th percentile driver) and since these side turn
36、signals are auxiliary devices (not required by FMVSS) which increase the conspicuity of the vehicle, a case can be made that vehicles equipped with these are safer than vehicles without them. Similarly, the left adjacent lane is analogous to the right, but more conservative because the drivers eye i
37、s farther away. The left adjacent lane elevation view shows that, at the 70 degree angle, a line drawn from the 1650 mm mounting height at a 10 degree down angle crosses a line drawn from the original 1220 mm mounting height at 5 degree down. At any distance beyond this intersection the higher mount
38、ed turn sign can be seen at a LOWER eye height. Since the drivers position is at 337 inches away from the signal and the intersection occurs at 190 inches the driver could easily detect the signal from the higher mounted turn signal.

41、tworking permitted without license from IHS -,- SAE J914 Revised JUL2003 Additional justification for the 15 degree down test point in conjunction with the 1650 mm mounting height is presented in a University of Michigan TRI study by Michael J. Flannagan. Ref. File: SAE TF 12-04-02.PPT “Side Turn Si
42、gnal Vertical Angles.” The changes proposed in this revision to the document are in response to requests from manufacturers. The larger vans and SUVs are designed to include side turn signals but the location exceeds the mounting height requirement in the current standard which is 1220 mm max. and 5
43、00 mm min. Several states have regulations which require compliance with the SAE Standard. The manufacturers goal is to conform to the standard so deviations or approvals will not be required from each state. Since side turn signals are not required by FMVSS 108 manufacturers need to meet the state
44、requirements. Most SAE signaling and marking device standards do not have mounting height requirements or guidelines in them. Therefore, these changes propose to delete the mounting height from the installation requirements section, 6.3.3 and add it to the installation guidelines section 7.1.1. Rela
