无须依赖国外,国内已开发出汽车故障诊断系统(OBD-II)
国内车载电脑专家-深圳市鑫合利科技有限公司,凭借本身的技术优势,日前已经成功的开发出车载诊断系统,从而结束了OBD2依赖国外的历史,为我国汽车行业的发展提供了良好的契机.
据悉,国Ⅲ标准将在全国统一实行，这将从很大程度上减少汽车尾气对大气的污染。而北京早已于今年1月1日，第一个在全国提前实施了国Ⅲ标准，上海和广州也分别于7月31日和9月1日实施了国Ⅲ标准。那么能否顺利实施、达到既定目标，这个问题的主要矛盾集中在车载诊断系统(OBD)和油品两个方面。次前OBD-II只能依赖国外进口,成本在3000-8000元左右,合利科技在推出OBD-II时,结合车载电脑能大大降低OBD-II系统的成本,而且还可以获得车载电脑,以及GPS卫星导航等相关功能!
