The invention discloses a sun-shading method for a vehicle. The method comprises the steps that whether sun-shading is needed or not is judged according to illumination intensity; if the illumination intensity exceeds the preset intensity, it is judged that sun shading is needed, and the intersection point of the driver eye position and the sun position on the vehicle body is obtained according to the driver eye position, the sun position and the vehicle driving data; and if the intersection point is located on the front windshield of the vehicle, sunlight shielding is conducted on the intersection point. According to the scheme, when the illumination intensity reaches or exceeds the preset intensity and the intersection point of the position of the sun and the position of the eyes of the driver on the vehicle body is located on the front windshield of the vehicle, sunlight shielding is conducted at the intersection point, and light is weakened. According to the mode, the shading position is more accurate and variable, accurate shading can be conducted according to the actual light incidence position, accordingly, multi-angle and multi-position shading is achieved, the defect that shading cannot be achieved by a sun shield under some conditions is overcome, and driving safety is facilitated.
本申请公开了一种本车辆遮阳方法,包括:根据光照强度判断是否需要遮阳;若光照强度超出预设强度,判定为需要遮阳,根据驾驶员眼睛位置、太阳位置及车辆行车数据得到驾驶员眼睛位置与太阳位置在车辆车身的交点;若交点位于车辆前风挡,则对交点位置处进行太阳光遮挡。通过本方案的遮阳方法,在光照强度达到或超出预设强度时,且太阳位置与驾驶员眼睛位置在车身的交点位于车辆前风挡时,在交点位置处进行太阳光遮挡,使光线减弱。此方式遮阳位置更准确且遮阳位置可变,能够根据实际光线入射位置进行准确遮光,从而实现多角度多位置遮光,避免了遮阳板在部分情况下无法实现遮光的弊端,有利于行车安全。
