技术领域 FIELD

[0001] 本发明涉及智能汽车领域,尤其涉及一种基于车联网的车辆远近光灯的智能控制方法。 [0001] The present invention relates to a smart vehicle, and more particularly, to a method for controlling intelligent networking vehicle based on the vehicle distance light lamp.

背景技术 Background technique

[0002] 目前物联网技术得到了快速发展,而车联网技术则是物联网技术在智能交通领域的具体应用。 [0002] Currently networking technology has been rapid development, and the vehicle networking technology is the concrete application of networking technology in the field of intelligent transportation. 车联网车载系统把车辆作为控制对象,同时将车辆当作信息节点,通过系统中每辆汽车对行驶环境信息进行感知采集,利用无线通信技术实现信息共享,对车辆进行大规模智能化统一管理,为用户提供了实时准确的信息査询、路线导航、故巧诊断和休闲娱乐等服务,有效改善人们的出行方式,增强道路交通的运输能力、预防或缓解交通事故的发生,减少道路交通对环境的污染和能源消耗,提升交管部口的管控能力,从而有利于缓解城市道路交通拥诸状况,解决城市交通问题。 Telematics vehicle system to the vehicle as a control object while the vehicle as an information node for running environment information collected by the perceptual system in each car, the use of wireless communication technology to share information, the vehicle for large-scale smart unified management, provides users with real-time accurate information inquiry, navigation route, so clever diagnosis and entertainment and other services, effectively improve the way people travel, the ability to enhance the transport of road traffic, prevent or mitigate traffic accidents and reduce road traffic on the environment pollution and energy consumption, improve traffic management on the mouth of the management and control capabilities to help alleviate urban road traffic hold various conditions, to solve urban traffic problems. 但目前车联网技术并未能对于车辆的远近光灯进行有效智能控制,仍无法完全避免对远近光灯的不合理使用而导致交通安全事故的问题,尤其是滥用远光灯的现象相当严重。 But the car networking technology and failure to respect the distance light vehicle effective intelligent control, can not completely avoid the problem of irrational use of distance light which led to traffic accidents, especially the abuse of high beam is quite serious. 远近光灯是汽车上重要照明设备之一,但若不合理使用远近光灯,会直接影响行车安全。 Distance light is one of the important automotive lighting equipment, but if the unreasonable use of distance light, can directly affect traffic safety.

[0003] 由于远光灯的光线平行射出,光线集中且亮度较大,照明度大;若在夜晚会车时, 使用远光灯会使对向驾驶员视觉上产生瞬间致盲,短时间内驾驶员如同闭眼开车,对周围的行人以及前后的来车观察能力基本为零。 [0003] Because of the high beam light emitted parallel light concentration and the brightness is large, a large illumination; at night when the car will be used to produce high beam to make an instant blinding the driver visually, short driving eyes closed as staff car to car observation and pedestrians around the front and rear of essentially zero. 并且车辆在开启远光灯的情况下,若行人在离车前15米左右处时,行人的身影将完全被灯光吞没,驾驶员无法看见行人。 And the vehicle in the case of the high beam is turned on, if a pedestrian at the front 15 meters from the vehicle, the pedestrian figure engulfment lights, the driver can not see the pedestrian. 另外,后方近距离的车辆若开启远光灯时,则前车的内外3个后视镜中将出现大面积光晕,缩小了后车前方路况的可视范围,而大大影响行车安全。 Further, if the rear of the vehicle near the high beam is turned on, the inside and outside rearview mirror 3 in the vehicle front halo large area, reducing the visual range of the car road ahead, greatly affect driving safety. 并且在遇到有雾、雨、雪、沙尘等低能见度的路面环境,以及进入隧道、无路灯时的外界光照强度过低的行驶环境时,因不合理使用近光灯和远光灯而导致行车事故的情况;因此若不能合理地对远近光灯的使用,会严重降低夜间的行车安全,大大增加危险事故的发生几率。 And in the event there are road conditions with low visibility fog, rain, snow, dust, etc., as well as into the tunnel, the outside light intensity when no lights low driving environment, due to the irrational use of high beam and low beam lights and lead to traffic accidents; therefore if it can not reasonably use the distance light can seriously reduce driving safety at night, greatly increasing the probability of occurrence of the risk of accidents. 因此,对于提出一种能够准确有效控制车辆远近光灯的方法,对车辆的安全行驶具有重要的社会意义。 Thus, for the proposed method for a vehicle capable of accurately and effectively distance light control, it has important social significance of safe driving the vehicle.
