Daytime running light linkage control strategy and daytime running lights

Abstract

The invention relates to a daytime running light linkage control strategy and daytime running lights. The control strategy is used for controlling light on or off of two or more sets of daytime running lights comprising a set of main lights and one or more sets of auxiliary lights. A control logic comprises that all sets of the lights are lighted on at the same time, when the main lights are off,the rest lights are controlled to be off; and when any group of the auxiliary lights are off, the rest lights are controlled to be off or the main lights are continuously controlled to be on. The sumof the luminous intensities of all sets of the lights is not more than 800cd and not less than 400cd, the control strategy is adopted, and each set of the lights includes an illuminant, an LED, an LEDcircuit board, an LED control module, and a linkage control module; the LED control module is connected with the LED circuit board, and the linkage control module is connected with a trip computer through a signal line in a communication mode. The daytime running light linkage control strategy and the daytime running lights can meet the regulatory requirements, and can meet the molding needs of the upper and lower sets of lights of main engine plants.

Description

technical field [0001] The invention relates to a control strategy of daytime running lights and the daytime running lights thereof, and belongs to the technical field of car lights. Background technique [0002] Daytime Running Light (DRL) is installed at the front of the car body, and it is a signal light for daytime driving, which can make the vehicle easier to be recognized by other vehicle drivers during daytime driving, especially in the driving line of sight environment In poor conditions, its effect on improving driving safety is more significant. [0003] Of course, the daytime running lights must meet the basic brightness requirements, but they should not be too bright, so as not to disturb others. According to the provisions of GB23255 on the light distribution performance of DRL, its luminous intensity should be between 400-800cd. [0004] There is only one group of existing daytime running lights on a car, including left daytime running lights and right daytim...

AI Technical Summary

Problems solved by technology

However, automobile OEMs have begun to have the need to install two or more sets of daytime running lights on a car, and require these sets of daytime running lights to be turned on at the same time, then According to the above-mentioned luminous intensity regulations of the GB23255 standard, in the case of two sets of lights, theoretically only the luminous intensity of a single set of lights is exactly 400cd to meet the above light distribution performance requirements, but this extreme situation does not have practical significance. It is even more impossible to set more sets of daytime running lights
