The invention discloses a vehicle headlamp irradiation angle adjusting method. The method comprises the steps that a front overhang height signal, a rear overhang height signal, an accelerator pedal travel signal, a brake pedal travel signal and a wheel rotating speed signal of a vehicle are collected in real time; according to the front overhang height signal and the rear overhang height signal, the current vehicle body height and pitch angle of the vehicle are obtained, and according to the accelerator pedal travel signal, the brake pedal travel signal and the wheel rotating speed signal, an acceleration signal, a brake signal and a vehicle speed signal are obtained; obtaining an initial irradiation angle of a vehicle headlamp, an initial vehicle body height of the vehicle, a vehicle body height correction parameter and a pitch angle correction parameter, and determining a target irradiation angle of the vehicle headlamp according to the initial irradiation angle, the initial vehicle body height, the vehicle body height correction parameter, the pitch angle correction parameter, the current vehicle body height and the pitch angle; the headlamp is adjusted from the initial irradiation angle to the target irradiation angle according to the acceleration signal, the braking signal and the vehicle speed signal, the adjusting precision is high, the driving safety is improved, and the cost is low.

    本申请公开了一种车辆大灯照射角度调节方法,包括:实时采集车辆的前悬高度信号、后悬高度信号、加速踏板行程信号、制动踏板行程信号和车轮转速信号;根据前悬高度信号和后悬高度信号获取车辆的当前车身高度和俯仰角,根据加速踏板行程信号、制动踏板行程信号和车轮转速信号分别获取加速信号、制动信号和车速信号;获取车辆大灯的初始照射角度、车辆的初始车身高度、车身高度修正参数和俯仰角修正参数,并根据初始照射角度、初始车身高度、车身高度修正参数、俯仰角修正参数、当前车身高度和俯仰角确定车辆大灯的目标照射角度;根据加速信号、制动信号和车速信号将大灯从初始照射角度调节至目标照射角度,调节精准度高,提高驾驶安全,成本低。
