The invention discloses a vehicle-mounted automatic headlamp control method, which comprises the following steps: performing power-on initialization on a vehicle body controller to enter a standby state; acquiring vehicle driving state information of the vehicle-mounted computer, and if the vehicle driving state information shows that the vehicle is in a driving state, executing the next step; detecting and compensating the vehicle top brightness Lg, the vehicle forward brightness Lf, the current vehicle environment temperature T and the current vehicle running speed Vs of the running environment of the vehicle in real time; and determining whether the size logic between the Lg* and the Lg*, the Lg* and the Lf* is established or not, and correspondingly controlling different combination states of the headlamp. The embodiment of the invention provides a vehicle-mounted automatic headlamp control method, by which the influence of the vehicle driving speed and the temperature of the vehicle driving environment on brightness acquisition in front of and above the vehicle and images of the vehicle entering special environments such as culverts, dusk, dawn and tree shade are fullyconsidered, so that real-time, accurate, effective and reliable control on the automatic headlamp is realized.

    本发明公开了一种车载自动大灯控制方法,其包括以下步骤:对车身控制器进行上电初始化,进入待机状态;获取车载电脑的车辆行驶状态信息,若车辆行驶状态信息为车辆处于行驶状态,则进入下一步;实时检测车辆所在行驶环境的车辆顶部光亮度Lg,车辆前向光亮度Lf,当前车辆环境温度T以及当前车辆行驶速度Vs并进行补偿;判断Lg*与Lg_t1*、Lg_t2*以及Lf*之间的大小逻辑是否成立,并对应控制大灯的不同组合状态。本发明的实施例提供了一种车载自动大灯控制方法,其充分考虑了车辆行驶速度、车辆行驶环境的温度对车辆前方和上方光亮度采集影响,以及车辆进入涵洞、黄昏、黎明、树荫等特殊环境的影像,从而实现实时、准确、有效、可靠的对自动大灯的控制。
