西安正昌电子着力提升商用汽车行车安全

如何提升商用汽车行车安全?通过主动安全装置介入车辆运行的状态,或者提醒驾驶员关注,来提升整车的安全性能,它作用在汽车事故发生之前,利用机电一体化装置尽可能地保持车辆的稳定性、可操纵性,让驾驶者能够恢复对车辆的控制,就可以最大限度避免意外发生,或者提醒驾驶人员对可能发生事故采取措施,以有效地避免事故的发生。

西安正昌电子股份有限公司就是这样一家专门从事商用汽车主动安全研发、生产、销售和服务的新三板上市企业,是陕西省科技厅认定的高新技术企业。该公司从主动安全的制动防抱死系统(ABS)、驱动防滑转(ASR)研发开始,历经18年的专业研发,其主营产品ABS、ASR、胎压监测系统目前在国内畅销,其最新推出的前向防撞预警系统、车道偏离预警系统、盲点监测系统,已经成熟并批量化应用于客车和个别厂家的货车,其商用车安全监控平台也开始进入推广阶段。

前方碰撞预警系统(FCW)

此系统可通过电脑对前方行驶或静止的车辆、车道内的行人等进行危险等级评估,在必要的时候对驾驶员进行预警警告,系统会持续对车辆行驶速度与前方障碍物的距离变化等信息进行快速评估,可以在发生碰撞危险前几秒钟发出警报,提醒驾驶员刹车。同时控制刹车灯,提醒后面汽车驾驶员注意,避免追尾。最大限度做到避免碰撞或减轻碰撞等级。简单说,该系统让车辆始终有一颗最明亮的双眼为驾驶者注视着前方。

车道偏离预警系统(LDW)

长途驾驶的时候,驾驶人员容易犯困,车辆会在驾驶员无意识时候,偏离正常行驶的车道。瞬间的车道偏离可能导致车辆和其他车道的车辆发生刮蹭,严重的可能引起重大交通事故。车道偏离预警系统借助摄像头对路两侧的分道线进行采集,再传到电脑进行数据分析,从而辨别车道,让车始终保持在车道中心行驶,当车辆无意识地偏离既定车道,预警系统会通过报警,起到提醒驾驶者的目的。

盲点监测系统(BSM)

盲点监测系统又叫并线辅助系统。在行车过程中,通过观察后视镜带来的信息是有限的,盲点监测系统可防止在并线过程中由于观察不仔细或观察不到后视镜盲区,所发生的交通事故。当驾驶员想要并线时,系统会自动扫描后方一定距离是否有潜在威胁(车辆两侧的后视镜盲区中的超车车辆),当系统监测到盲区有车辆时,会以报警或是灯光闪烁等方式提示驾驶员此刻不宜变道,从而避免交通事故的发生。

胎压监测系统(TPMS)

它的作用是在汽车行驶过中对轮胎气压进行实时自动监测,当轮胎出现漏气、高压、低压、高温时,系统就会进行报警提示驾驶员,以确保行车安全。数据表明,由爆胎引起的车祸在恶性交通事故中所占比例非常高,达到70%以上,而这其中造成轮胎爆胎的因素绝大部分都是因为胎压不足。

西安正昌电子生产的以上主动安全产品在车辆运行过程中,就像给驾驶员增加了许多助手,不停地监控前向车道内的车辆、行人,以及车辆是否偏离正常车道,车辆变道时,目标车道是否存在可能发生碰撞的车辆等等;甚至可以通过车辆的安全监控平台,将车辆行车时的运行状态数据及驾驶员的驾驶行为信息数据,进行远程监控(如本车与前车的车距是否保持正常、变道时是否有打开转向灯,是否存在超速行驶等等),通过有效的二级远程监管,确保车辆正常行驶的安全性。
