Intelligent turn-off method and turn-off control device for high beam of running vehicle

Abstract

The invention relates to an intelligent turn-off method and turn-off control device for a high beam of a running vehicle. The method includes the steps that the surrounding luminance L is continuously detected through the high-beam turn-off control device on the vehicle, and when L is greater than Lth, it is judged that a coming vehicle on the opposite side gives out an obstructive high beam signal, and then the current running speed v of the vehicle and a speed threshold value vth are compared; when v is greater than or equal to vth, the high beam is not operated and controlled; and when v is smaller than vth and the high beam of the vehicle is turned on, the high beam of the vehicle is turned off. The turn-off control device comprises a luminance sensor, a speed sensor, a first comparator, a second comparator, an And gate, a driving circuit and a high beam switching circuit. The intelligent turn-off method and turn-off control device have the advantages that the view of a driver of the coming vehicle on the opposite side is not affected by the high beam of the vehicle, the normal using state of the high beam of the vehicle is also considered, and therefore safety can be guaranteed, and normal operation of a driver of the vehicle is not affected.

Description

technical field [0001] The invention relates to high beam control, in particular to a method for intelligently closing the high beam of a running vehicle and a closing control device. Background technique [0002] According to the relevant provisions of the national "Road Traffic Safety Law", there are 6 situations where high beams cannot be used, so the use of high beams is more complicated. In reality, it is more common to use high beams incorrectly, and reports of traffic accidents are not uncommon. Among them, there are many drivers who use high beams incorrectly and cause them unconsciously. Therefore, it is particularly necessary to design a corresponding device for controlling high beams to be turned off. [0003] Therefore, some methods to try to solve the above problems have been proposed at present. For example: use the light sensor to detect whether the surrounding of the vehicle is well-lit, and if so, automatically turn off the high beam of the vehicle. But w...

Problems solved by technology

In addition, in these methods disclosed in the existing literature, there is a problem that the light detection effect is greatly affected by moonlight, street lamps, scattered light, etc., and the effect is not very good.
