The invention relates to the technical field of vehicle lamp control, and provides a method for extracting a vehicle lamp control signal through multi-information fusion. According to the method, navigation information such as time information, position information and signal receiving strength information is obtained from a vehicle navigation module, then the time information and the position information are subjected to joint analysis to judge day and night type information, road information is obtained according to the position information, and information of a site where a vehicle is located is judged according to the signal receiving strength information. The day and night type information, the road information and the site information are fused to generate a variable control signal for controlling the vehicle lamp, so that the adjustment of the vehicle lamp can be controlled in a fine-grained manner through the change of the control signal of the vehicle lamp, and the vehicle is helped not to depend on a light sensor; effective and accurate control of the vehicle lamp is achieved only through extraction, analysis and fusion of the vehicle navigation information, the defect that a light sensor is low in working precision in rainy days is overcome, the control precision of the vehicle lamp is improved, the light sensor does not need to be installed, and the manufacturing cost of the vehicle is reduced.
本发明涉及车灯控制技术领域,提出了一种多信息融合提取车灯控制信号的方法。该方法从车辆导航模块获取时间信息、位置信息和信号接收强弱信息等导航信息,然后对时间信息和位置信息进行联合分析判断出昼夜类型信息,并根据位置信息获取道路信息、根据信号接收强弱信息判断车辆所处场地信息,再将昼夜类型信息、道路信息及场地信息进行融合生成可变的控制车辆车灯的控制信号,从而可以通过车灯的控制信号的变化可以细粒度地控制车灯的调整,帮助车辆不依赖光线传感器,仅通过车辆导航信息的提取、分析融合实现对车灯的有效精准控制,弥补光线传感器在雨天工作精度低的缺陷,提高车灯控制的精确度,且不用安装光线传感器,降低了车辆的制造成本。
