Breathing courtesy lamp control method and system, vehicle and storage medium

Abstract

The invention discloses a breathing courtesy lamp control method and system, a vehicle and a storage medium. The method comprises the steps that when the vehicle receives an unlocking signal, a vehicle body controller outputs a breathing greeting signal to a front combined lamp and a rear combined lamp, and the vehicle body controller supplies power to a front steering lamp and a rear steering lamp at the same time within the time period of 0-T1; supplying power to the front steering lamp and the rear steering lamp is stopped within the time period of T1-T2; power is supplied to the front position lamp, the rear position lamp and a daytime running lamp at the same time within the time period of T2-T3; power is continuously supplied to the daytime running lamp within the time period of T3-T4, and a first PWM signal with a specific frequency and a duty ratio of 0-100% is output to the front position lamp and the rear position lamp; and a first PWM wave output by an automobile body controller is recognized through the driving module of the front combination lamp, and a second PWM signal with the same duty ratio is output to the LED light source module, so the filtering effect of a circuit on the PWM wave can be avoided, it is guaranteed that lamplight response is consistent with the PWM signals output by the automobile body controller, and a good breathing greeting effect is formed.

Description

technical field [0001] The invention belongs to the technical field of automobile lighting systems, and in particular relates to a method, a system, a vehicle and a storage medium for controlling a breathing welcome light. Background technique [0002] With the rapid development of the automobile industry, consumers have higher and higher requirements on the appearance of vehicles, so the lighting effects on vehicles are also more and more valued by vehicle manufacturers. In order to improve the perception of lamps and lanterns, some cars with breathing welcome effect functions have gradually appeared on the market. At present, the breathing welcome effect of automobile lamps is driven by the PWM signal output by the body controller, so as to achieve the effect of light breathing. Since the front position lamp and daytime running lamp in the front combination lamp adopt PWM dimming, there is a filter circuit, which has a filter effect on the PWM signal output by the body co...

AI Technical Summary

Problems solved by technology

This solution can solve the problem of errors in PWM signal transmission, but it needs to pre-store the welcome lighting animation effect and corresponding relationship table in the lighting controller MCU in advance. This solution takes up a lot of memory space in the controller, which is not conducive to reducing costs Unable to update the welcome animation effect
