3、LCA Lane Change Decision Aid
ISO 17387 Introduction 介绍
Lane Change Decision Aid Systems (LCDAS) warn the driver against collisions that
may occur due to a lane change manoeuvre. LCDAS are intended to supplement
the vehicle’s interior and exterior rear-view mirrors, not eliminate the need for such
mirrors. LCDAS are intended to detect vehicles to the rear and sides of the subject
vehicle (see Figure 1). When the subject vehicle driver indicates the desire to make
a lane change, the system evaluates the situation and warns the driver if a lane
change is not recommended. LCDAS are not meant to encourage aggressive
driving. The absence of a warning will not guarantee that the driver can safely make
a lane change manoeuvre. The system will not take any automatic action to prevent
possible collisions. Responsibility for the safe operation of the vehicle remains with
the driver.
车道变更决策辅助系统(LCDAS)警告驾驶员可能因换道机动而发生
碰撞。LCDAS旨在补充车辆的内部和外部后视镜,而不是消除这种镜
子的需要。LCDAS旨在检测车辆的后方和侧面(见图1)。当主体车辆
驾驶员指示希望进行车道改变时,系统评估该情况,并且如果不建议改
变车道,则警告驾驶员。LCDAS并不意味着鼓励积极的驾驶。 没有警
告并不能保证驾驶员可以安全地进行换道机动。系统不会采取任何自动
行动来防止可能的冲突。 驾驶员对车辆的安全操作负责。
Note Many figures in this documents show vehicle on roadways with
lane markings. This is not meant to imply that lane marking recognition
or lane detection is required for an LCDAS. The lane markings are
drawn for reference only.
本文件中的许多数字显示车道上有车道标记的车辆。这并不意味着要求
LCDAS需要车道标记识别或车道检测。车道标记仅供参考。

2、ISO 17387 Terms and definitions术语和定义
SN.
Terms Definitions
2.1 subject vehicle vehicle equipped with the system in question and related to the topic of discussion
装备有与讨论的话题有关的系统的车辆
2.2 LCDAS target vehicle any vehicle that is closing in on the subject vehicle from behind, or any vehicle that is located in one
of the adjacent zones
NOTE An LCDAS target vehicle is referred to as “target vehicle” in this document.
任何从后面靠近主体车辆的车辆,或位于相邻区域之一的任何车辆
注:在本文件中,LCDAS目标车辆被称为“目标车辆”。
2.3 coverage zone entire area to be monitored by an LCDAS, a system’s coverage zone consisting of a specific subset
of the following zones: left adjacent zone, right adjacent zone, left rear zone and right rear zone
NOTE A target vehicle located within the coverage zone will thus be detected by the system.
在整个区域由LCDAS监视,系统的覆盖区由下列区域的特定子集组成:左侧相邻区,右侧相邻区,左
后侧区和右后侧区 注:位于覆盖区内的目标车辆将被系统检测到。
2.4 adjacent zones
zones to the left and right of the subject vehicle 目标车辆的左侧和右侧区域
See Figure 见图 2.
NOTE The adjacent zones are intended to cover the lanes adjacent to the subject vehicle. However, the position and size
of the adjacent zones are defined with respect to the subject vehicle, and are independent of any lane markings.
注:相邻区域用于覆盖与主体车辆相邻的车道。
然而,相邻区域的位置和大小是相对于本车限定的,并且与任何车道标记无关。
2.5 rear zones
zones that are behind and to the sides of the subject vehicle 在车辆后方和侧面的区域
See Figure 见图 3.
NOTE The rear zones are intended to cover the lanes adjacent to the subject vehicle. However, the position and size of the
rear zones are defined with respect to the subject vehicle, and are independent of any lane markings.
注:后部区域用于覆盖与主体车辆相邻的车道。 但是,后方区域的位置和大小是相对于主体车辆而定义的,并且与任何车道标
记无关。
2.6 rear zones 〈of a target vehicle〉 lateral distance between the side of the subject vehicle and the near side of a
target vehicle
<对于目标车辆> 主体车辆的侧面和目标车辆的近侧之间的横向距离
See Figure 见图 4.

2、ISO 17387 Terms and definitions术语和定义
SN.
Terms Definitions
2.7 rear clearance 〈of a target vehicle〉 distance between the rear of the subject vehicle and the front of the target
vehicle as measured along a straight line, or optionally, as estimated along the target vehicle’s
estimated path See Figures 5 a) to 5 d). NOTE This definition applies to target vehicles in the rear zones only.
<对于目标车辆> 在沿着直线测量的主体车辆的后方与目标车辆的前方之间的距离,或者可选地
沿着目标车辆的估计路径估计的距离 参见图5a)至5d)。注意:注此定义仅适用于后方区域的目标车辆。
