5、vised 2015-06 Superseding J2802 JAN2010 Blind Spot Monitoring System (BSMS): Operating Characteristics and User Interface RATIONALE The current document recommends a visual BSMS indicator. BSMS detects and conveys to the driver via a visual indicator the presence of a target (e.g., vehicle) adjacent
6、 to the subject vehicle in the traditional Adjacent Blind Spot Zone (ABSZ). The purpose of this update is to change the ISO symbols in 4.2.1.2 to the latest ISO symbol for ide Object Detection. FOREWORD This recommended practice is intended to be consistent only with the “Blind Spot Warning Function
7、” in ISO FDIS 17387-Lane Change Decision Aid System. The functionality of the “Closing Vehicle Warning” and the “Lane Change Warning” are not considered in this document. TABLE OF CONTENTS 1.

SCOPE This document specifies the minimum recommendations for Blind Spot Monitoring System (BSMS) operati
11、onal characteristics and elements of the user interface. A visual BSMS indicator is recommended. BSMS detects and conveys to the driver via a visual indicator the presence of a target (e.g., a vehicle), adjacent to the subject vehicle in the “traditional” Adjacent Blind Spot Zone (ABSZ). The BSMS is
12、 not intended to replace the need for interior and exterior rear-view mirrors or to reduce mirror size. BSMS is only intended as a supplement to these mirrors and will not take any automatic vehicle control action to prevent possible collisions. While the BSMS will assist drivers in detecting the pr
13、esence of vehicles in their ABSZ, the absence of a visual indicator will not guarantee that the driver can safely make a lane change maneuver (e.g., vehicles may be approaching rapidly outside the ABSZ area). This document applies to original equipment and aftermarket BSMS systems for passenger vehi
14、cles. This document does not apply to installing a BSMS on either motorcycles or commercial vehicles. Finally, this document does not address Lane Change Warning systems, which monitor areas substantially farther back than the side blind spot areas monitored by the BSMS (See ISO FDIS 17387). 2. REFE

26、cycle, except those excluded in 3.5.2 and 3.5.3. 3.5.2 Optional Targets Pedestrians, pedalcyclists, or motor vehicles with an engine less than 125 cc.

30、5 Page 5 of 10 FIGURE 1 - ABSZ, AS DEFINED BY ISO FDIS 17387 3.7 ADJACENT BLIND SPOT ZONE (ABSZ) Zones to the left and right of the subject vehicle that extend into the adjacent lane. The exact size, position, and shape of the zones are given in Figure 1. 3.8 VISUAL INDICATOR Visual signal given to
31、the driver of the SV when a target has been detected in the ABSZ and the criteria (discussed in 4.1.2) have been met. 3.9 FMVSS 111 VIEWING TRIANGLE A triangular plane defined in the U.S. DOT FMVSS 111 Rearview Mirrors, that the driver must be able to see in the rearview mirror. The viewing triangle
32、 is outlined by points A, B, and C in Figure 2. SAE INTERNATIONAL J2802 Revised JUN2015 Page 6 of 10 FIGURE 2 - FMVSS 111 VIEWING TRIANGLE 4. REQUIREMENTS 4.1 Operational Characteristics 4.1.1 Operational Speed The system shall be operational when the vehicle is in a forward gear at a minimum speed
33、of 60 km/hr (37.3 mph). The system may be operational at lower forward speeds. As the system is intended to monitor the blind spot of the vehicle while moving forward, it should not be operational when the driver is in reverse or park gear. 4.1.2 Criteria for Eliciting a Visual Indicator 4.1.2.1 Loc
34、ation in ABSZ on Left Side Using Figure 1 as a reference, all of the target shall be located behind line C and to the left of line F and any part of the target vehicle shall be in front of line B and to right of line G to elicit a visual indicator. 4.1.2.2 Location in ABSZ on Right Side Using Figure
35、 1 as a reference, all of the target shall be located behind line C and to the right of line K and any part of the target vehicle shall be in front of line B and to left of line L to elicit a visual indicator. 4.1.2.3 Targets The BSMS shall give a visual indicator for mandatory targets. The BSMS may
36、 give a visual indicator for optional targets. The BSMS should not give visual indicators to non-targets. 4.1.3 Deactivation 4.1.3.1 User Deactivation The user shall be informed of the activation state (i.e., system active, system not active) at start-up, or whenever the state changes. A user may be
37、 provided with a means to deactivate and reactivate the system. The system may automatically reactivate upon the next ignition cycle. SAE INTERNATIONAL J2802 Revised JUN2015 Page 7 of 10 4.1.3.2 Qualified Technician Deactivation A method may be provided that allows the customer to have the system pe
38、rmanently deactivated by a qualified technician. Allowing the customer to permanently deactivate the system via a qualified technician is intended to accommodate customers who view the system as an annoyance. 4.1.4 Fault Indication The system shall notify the driver at the time of the fault and at a
39、ll subsequent vehicle ignition cycles during which there is a system fault. 4.2 Displays A visual indicator shall be used to notify the driver that a target is detected in the ABSZ, regardless of whether there is sufficient evidence that the driver is planning or executing a lane change maneuver in
40、the direction of a target detected in the ABSZ. 4.2.1 Visual 4.2.1.1 Location One indicator shall be dedicated to the left ABSZ and another indicator shall be dedicated to the right ABSZ. The displays shall be located on, or in close proximity to, each side view mirror. This recommendation is intend
41、ed to help ensure that drivers continue to check their mirrors before changing lanes, which is necessary for detecting vehicles outside the ABSZ areas, particularly rapidly approaching vehicles. The Kiefer and Hankey (2008) in-traffic study suggests that placing the BSMS indicators attached directly
42、 to the mirror or in the mirror will reduce the number of lane changes attempted without checking mirrors relative to a baseline (no BSMS system available) condition. This display placement recommendation also provides a means of addressing any potential risks associated with drivers that incorrectl
43、y assume that the BSMS monitors areas beyond the ABSZ areas. In addition, placing the BSMS indicators (particularly the BSMS symbol; see 4.2.1.2) either in the mirror or attached directly to the mirror may help drivers comprehend the meaning of the blind spot indicator. The visual indicator, if posi
44、tioned on the reflective surface of the outside rearview mirror shall be placed outside the area of the mirror that encompasses the FMVSS 111 viewing triangle. 4.2.1.2 Use of ISO Symbols The ISO Side Object Detection symbols, illustrated in Figure 3, should be used as either the visual indicator or
45、as the identifier for the visual indicator (K.17, ISO/IEC registration number 7000-2796). FIGURE 3 - ISO SIDE OBJECT DETECTION SYMBOLS SAE INTERNATIONAL J2802 Revised JUN2015 Page 8 of 10 The symbol on the passengers side should be displayed as a reverse image of the drivers side symbol. This use of
46、 symbols should aid in a correct interpretation of the relationship between the subject vehicle compared to a target in their blind spot. If the ISO symbol is not used as the visual indicator, a solid color, point source (i.e., an LED) may be used. The ISO symbol should be used to identify the point
47、 source. 4.2.1.3 Color The ISO symbol or point source should be illuminated in amber. It shall not be illuminated in red. 4.2.1.4 Luminance The light source of the visual indicator should be capable of achieving at least 6000 cd/m2for daytime usage. The display should have the ability to be dimmed a
48、t night so as to mitigate the potential that the display is a source of annoyance glare or possibly disability glare. For example, this dimming may be achieved through an automatic ambient light control or sensor, in conjunction with headlamp operation, or via a separate manual control. The measurem
49、ents of luminance should be taken with the photometer located at the centroid of the driver cyclopean eyellipse (SAE J941) and aimed at the center of the illuminated surface of the BSMS visual indicator on each side of the vehicle. Figure 4 provides sample values for such an approach applied to the drivers side visual indicator. The photometer is angled 42 degrees horizontally outboard, 12 degrees down a
