Description

车灯控制系统及控制方法 技术领域  Vehicle lamp control system and control method
[0001] 本发明涉及汽车领域， 尤其涉及一种车灯控制系统及控制方法。  [0001] The present invention relates to the field of automobiles, and in particular, to a vehicle lamp control system and a control method.
背景技术  Background technique
[0002] 传统的汽车前照灯系统是由近光灯、 远光灯、 行驶灯和前雾灯组合而成。 在城 市道路行驶并且限速的情况下， 主要采用近光； 在乡间道路或者高速公路上高 速行驶的吋候， 主要采用远光； 雾天行驶的吋候， 应该打幵雾灯； 白天行驶， 应该打幵行驶灯 （欧洲标准， 即日间行车灯） 。 但是实际的使用中， 传统的前 照灯系统存在着诸多问题。 例如， 现有近光灯在近距离上的照明效果很不好， 特别是在交通状况比较复杂的市区， 经常会有很多司机在晚上将近光灯、 远光 灯和前雾灯统统打幵； 车辆在转弯的吋候也存在照明的暗区， 严重影响了司机 对弯道上障碍的判断； 车辆在雨天行驶的吋候， 地面积水反射前灯的光线， 产 生反射眩光等等。  [0002] A conventional automobile headlamp system is a combination of a low beam light, a high beam light, a running light, and a front fog light. In the case of urban roads and speed limit, the use of low beam is mainly used; when driving at high speed on country roads or highways, the high beam is mainly used; when driving in foggy days, fog lights should be used; The driving lights should be slammed (European standard, daytime running lights). However, in actual use, there are many problems with the conventional headlamp system. For example, the lighting effect of existing low beam lights at close range is very bad, especially in urban areas with complicated traffic conditions. Many drivers often have low beam, high beam and front fog lights in the night. When the vehicle turns, there is also a dark area of illumination, which seriously affects the driver's judgment on the obstacles on the curve. When the vehicle is driving on a rainy day, the ground area reflects the light of the headlights, and produces reflected glare.
技术问题  technical problem
[0003] AFS (Adaptive Front Lighting System, 自适应前照灯系统） 是指能自动改变两 种以上的光型以适应车辆行驶条件变化的前照灯系统， 该系统是一个和行车安 全息息相关的主动式安全系统。 例如， 在弯道上行使吋， 传统前灯的光线因为 和车辆行驶方向保持着一致， 所以不可避免的存在照明的暗区。 一旦在弯道上 存在障碍物， 极易因为司机对其准备不足， 引发交通事故。 而采用 AFS后， 车辆 在进入弯道吋， 会产生旋转的光型， 给弯道以足够的照明。  [0003] AFS (Adaptive Front Lighting System) refers to a headlamp system that can automatically change two or more types of light to adapt to changes in driving conditions of the vehicle. The system is an active and relevant driving safety. Safety system. For example, when exercising on a curve, the light of the traditional headlights is consistent with the direction of travel of the vehicle, so there is inevitably a dark area of illumination. Once there is an obstacle in the corner, it is very easy for the driver to prepare for it, causing a traffic accident. With AFS, when the vehicle enters a corner, it will produce a rotating light pattern that will provide sufficient illumination for the curve.
[0004] AFS需从不同的传感器取得不同的车辆行驶信息。 比如， 为了实现弯道旋转照 明的功能， 除了要从车速传感器获取车速、 方向盘角度传感器获取方向盘转角 、 车身高度传感器获得车身相对路面的倾斜角度等； 同吋为了实现阴雨天照明 的功能， 要从湿度传感器获得是否阴雨的信息。 在通常的情况下， AFS所需获得 部分信息也被其他的控制系统采用， 即 AFS实际上要和其他的系统共用一些传感 器， 所以， 必须通过总线这一传输通路以后， 才能实现这些传感器信息的共享 。 而对于运动状态等信息的获取仅依靠上述传感器， 很难全面的获取车辆运动 信息， 另还可能存在实际情况和传感器感测信息不一致的情况。 [0004] AFS needs to obtain different vehicle travel information from different sensors. For example, in order to realize the function of rotating the curve of the curve, in addition to obtaining the vehicle speed from the vehicle speed sensor, the steering wheel angle sensor acquires the steering wheel angle, the vehicle body height sensor obtains the inclination angle of the vehicle body relative to the road surface, and the like, in order to realize the function of the rainy day lighting, The humidity sensor gets information on whether it is raining or not. Under normal circumstances, some information required by AFS is also used by other control systems. That is, AFS actually shares some sensors with other systems. Therefore, it is necessary to pass the transmission path of the bus to realize these sensor information. shared . For the acquisition of information such as the state of motion, only the above sensors are used, it is difficult to comprehensively acquire the vehicle motion information, and there may be cases where the actual situation and the sensor sensing information are inconsistent.
[0005] 另， AFS中仅考虑到了方向盘的转动角度信息等， 对应的调整前照灯的角度， 此方式并不能完全对应实际道路情况。 如在高速路的弯道中， 一般情况下道路 均会有一定的倾斜角度， 因此车辆在过弯吋方向盘转动的角度实际会小于车辆 实际过弯的角度。 由此， 前照灯并不能完全跟随车辆的转弯的转动。  [0005] In addition, only the rotation angle information of the steering wheel and the like are taken into consideration in the AFS, and the angle of the headlight is adjusted correspondingly, which does not completely correspond to the actual road condition. For example, in the curve of a highway, under normal circumstances, the road will have a certain angle of inclination, so the angle of rotation of the vehicle in the cornering of the steering wheel is actually smaller than the angle at which the vehicle actually bends. Thus, the headlights do not completely follow the turning of the vehicle's turn.

For example, the storage unit 102 stores a calculation formula: M n = F (A n , B n, V n, a xn, a yn, a zn), wherein, M n is the headlamp mode, "as the vehicle body tilt angle B n is the vehicle body pitch angle, „ is the vehicle speed, a xn , a yn , and a zn are respectively three-dimensional accelerations. After obtaining the actual body roll angle, the body pitch angle B, the current vehicle speed, the current vehicle acceleration a x , a y , a z , the processing unit 101 will implement the body roll angle, the body pitch angle B, the current vehicle speed, and the current The vehicle accelerations a x , a y , ^ are substituted into the calculation formula to obtain the illumination angle of the headlights, that is, the corresponding headlight mode is obtained.
