Vehicle-high-beam control method and system based on light-dependent-resistor photometry

Abstract

The invention discloses a vehicle-high-beam control method based on light-dependent-resistor photometry. The vehicle-high-beam control method includes the following steps of (1) light condition obtaining, wherein a plurality of light dependent resistors are put on a vehicle, and light conditions of different angles on the periphery of the vehicle are obtained; (2) voltage collecting, wherein voltage at the two ends of each light dependent resistor is collected; (3) control command generating, wherein the voltage at the two ends of each light dependent resistor is comprehensively analyzed, thelight conditions nearby the vehicle are judged, and a control command for controlling vehicle lamplight is generated; (4) sending, wherein the control command is sent to a vehicle control system, andthe vehicle control system controls the vehicle lamplight. The vehicle-high-beam control method based on light-dependent-resistor photometry has the advantages that the cost is low, and the reliability is high; a system is automatically switched, and weariness brought by frequent operation of a driver is effectively released; 3, traffic risk brought by high-beam lighting is effectively controlled,vehicle lamps are reasonably controlled to be used, and traffic safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile light control, in particular to an automobile high beam control method and system based on photometry of a photoresistor. Background technique [0002] In recent years, the vigorous development of the automobile industry and the rapid increase in the number of automobiles have provided great convenience for people's travel, but also brought huge traffic problems, which have also caused many traffic accidents. Therefore, traffic safety problems are becoming more and more serious. has attracted more and more people's attention. Compared with the normal daytime, due to the poor lighting conditions when driving at night or in fog, the driver's visual ability is limited to a certain extent, and pedestrians and non-motor vehicles are often in danger due to the visual limitations of car drivers. . Therefore, the risk of driving at night or in fog is higher. In order to improve the safety of drivers...

Problems solved by technology

At present, the most common way to obtain this effect is that the driver turns on the high beam, but if the high beam is always on, it will seriously interfere with the oncoming vehicle, so that the driver on the opposite side cannot see the road clearly, because the traffic accidents caused by turning on the high beam account for the night time. More than 30% of traffic accidents, and it is on the rise. Therefore, the traffic law stipulates the conditions for turning on the high beams. It is illegal to turn on the high beams in violation of the regulations. The all-weather intelligent high beam control system is to meet the driver's lighting needs. At the same time, it automatically and intelligently switches to suitable lighting when it is not suitable to turn on the high beam.
