The invention provides a steering pattern ground projection control method based on an automobile projection lamp. The method comprises the following steps: acquiring steering motion state parameters of a steering sensor; performing rotation projection difference processing on the steering motion state parameter and a preset steering parameter to obtain a projection steering difference component; and transmitting a steering projection on-off signal to a steering projection controller according to the projection steering difference component. After the steering motion state parameters are collected, the steering condition of the steering sensor in the current automobile moving process is determined, and then the steering motion state parameters are compared with the standard steering state parameters, so that the difference between the current automobile steering state of the steering sensor and the standard automobile steering state is conveniently determined; and finally, according to the difference value, the projection working mode of each steering projection light source is adjusted through the steering projection controller, so that the on-off state of the steering projection light source is conveniently adjusted, and the timeliness of surrounding warning is effectively improved.
本公开提供一种基于汽车投影灯的转向图案地面投影控制方法。所述方法包括获取转向传感器的转向运动状态参数;将转向运动状态参数与预设转向参数进行转投差分处理,以得到投影转向差分量;根据投影转向差分量向转向投影控制器发送转向投影启闭信号。在对转向运动状态参数采集后,对转向传感器的当前汽车移动过程中转向情况进行确定,之后将转向运动状态参数与标准的转向状态参数进行比对,便于确定转向传感器当前的汽车转向状态与标准汽车转向之间的差异,最后根据上述差异值,通过转向投影控制器对各转向投影光源的投影工作模式进行调整,便于对转向投影光源的开关状态进行调整,有效提高了对周围示警的及时性。
