乘用车A柱盲区的校核方法

在驾驶员视野优化设计中，A柱盲区是影响汽车主动安全的重要因素之一，所以对A柱盲区的校核应给予足够的重视。文章用SAE眼椭圆、GB11562-94和RAMSIS眼点3种方法在同一个状态的驾驶姿势下对A柱盲区进行了校核．并对得到的3种不同结果进行了比较分析。结果表明，测得的双目障碍角中，RAMSIS眼点的结果〉SAE眼椭圆的结果〉GB11562-94的结果；在校核过程中，RAMSIS眼点比其他2种方法操作过程简单，在校核时间上占有优势。

Verification Method of A-pillar Obstruction of Passenger Car

In optimized design of driver＇s field of view, A-pillar obstruction is an important factor influencing automotive active safety, verification of A-pillar obstruction should be paid adequate attentions. In this paper, three-methods of SAE eye ellipse, GB 11562-94 and RAMSIS eyespot is used for checking A-pillar obstruction in the same driving position, with a comparative analysis of its results. The results indicated that the measured obstacle angle of two-eyes visibility, the result of RAMSIS eyespot is bigger than that of SAE eye ellipse and GB 11562-94; in verification process, RAMSIS eyespot is simpler than that of two methods and it has advantages in verification time.
