Control method and system of steering lamp and vehicle

Abstract

The invention provides a control method and system of a steering lamp and a vehicle and relates to the field of vehicles. The control method of the steering lamp comprises the steps of receiving a triggering instruction for turning on the steering lamp first; and then controlling a first working circuit to be started according to the triggering instruction and simultaneously providing multiple groups of light-emitting modules of the steering lamp with a first working current, which is lower than a steering lamp normal working current, for the multiple groups of light-emitting modules to emit lights; after the multiple groups of light-emitting modules emit lights, controlling a second working circuit to be started and providing a second working current, which is equal to the steering lamp normal working current for the multiple groups of light-emitting modules within a first preset threshold time range in sequence so as to control the multiple groups of light-emitting modules to enhancethe brightness in sequence; and finally, after the multiple groups of light-emitting modules works normally for a second preset threshold time, controlling the first working circuit and the second working circuit to be closed to stop supplying power to the multiple groups of light-emitting modules so that the multiple groups of light-emitting modules are simultaneously turned off. The control method of the steering lamp has the advantages of more complicated steering lamp turn-on control form and richer expression form.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a control method, system and vehicle for a turn signal lamp. Background technique [0002] The turn signal is used to prompt the surrounding environment of the vehicle that the vehicle has a tendency to turn, which is related to driving safety. At present, the realization forms of the turning lights are generally as follows: 1. All the light sources of the turning lights are turned on together and then all cut off in one flash cycle. That is to say, each flashing cycle is composed of an activation period (during which the turn signals are all illuminated together) and a non-activation period (during which the turn signals are all kept dark), during which the turn signals are active and inactive Appears repeatedly to achieve flickering. 2. Part of the light sources of the turn signal lights up preferentially in a flash cycle, and then the remaining light sources are turned on in sequence...

Problems solved by technology

[0003] The purpose of the first aspect of the present invention is to provide a control method for turn signals to solve the problems in the prior art that the turn signals are implemented in a single form and the turn performance is not obvious
