智能汽车多传感器融合技术专利分析

The Patent Analysis of the Multi-Sensor Information Fusion Technology in Intelligent Vehicle

在车辆上设置传感器用以感知车辆周围环境态势,从而使得车辆能够根据感知信息进行自主决策,进而实现自主行驶,这是汽车智能化的重要环节。然而不同类型的传感器有着各自的长处与短板,若车辆仅依赖单一类型的传感器,难以保证获取信息的全面性与可靠性。如何利用融合技术进行车载传感器信息的融合,从而进行高效、准确的决策,是全球汽车业界关注的问题,对于我国智能汽车产业的发展有着十分重要的现实意义。本文通过专利分析对全球及中国的智能汽车多传感器信息融合技术专利信息进行提取、分析、整合,总结出其发展路线与趋势,为各方的相关决策提供参考。

Sensors are set on the vehicle in order to sensing the enviroment around, so that the vehicle can make decisions upon the perceived information, and achieve autonomous driving, which is an important part of the vehicle intellectualization. However, different types of sensors have different characteristics. It is difficult for the vehicle to guarantee the comprehensive and effective information from single type of sensors. The global automotive industry concerns about how to fuse the information from different sensors by multi-sensor information fusion technology in order to achieve efficient and accurate decision. And it also has an important realistic meaning for the intelligent ve-hicle industry of China. This paper analyses the patents of the multi-sensor information fusion technology in intelli-gent vehicle in global and China, summarizes the developing route and trend to provide reference for the policy.
