The invention discloses an automobile power domain multi-source information fusion method and system based on an intelligent tire. The method comprises the steps that multi-source information influencing an automobile power domain is obtained through the intelligent tire; comprise tire force, pavement excitation and acceleration; the method comprises the following steps: extracting multi-source information acquired by an intelligent tire, storing time domain acquisition information of sensors in respective hard disk spaces in real time in a text or binary form, and preprocessing the multi-source information; fusing the multi-source data at a data level, and correcting fused information at a feature level; and uploading the fusion information to a cloud. According to the automobile power domain multi-source information fusion method based on the intelligent tire, the intelligent tire technology is considered to directly obtain the multi-source information of the vehicle and road surface influence power domain, and the basic information of automobile power domain control can be more comprehensively and more accurately obtained by considering the multi-source information; and moreover, the high efficiency and reliability of multi-source information fusion can be ensured, and a data basis is provided for subsequent automobile power domain control.

    本发明公开了一种基于智能轮胎的汽车动力域多源信息融合方法及系统,包括:利用智能轮胎获取影响汽车动力域的多源信息;包括:轮胎力、路面激励、加速度;将智能轮胎获取到的多源信息进行提取,将传感器时域采集信息分别以文本或二进制形式实时存储在各自的硬盘空间中,并对多源信息进行预处理;对多源数据在数据级进行融合,并在特征级对融合信息进行修正;上传融合信息至云端。本发明提出的基于智能轮胎的汽车动力域多源信息融合方法,考虑智能轮胎技术直接获取车辆与路面影响动力域的多源信息,考虑多源信息可以更全面、更准确的获取汽车动力域控制的基本信息,而且可以保证多源信息融合的高效性与可靠性,为之后的汽车动力域控制提供数据基础。
