Passenger car tail lamp and passenger car tail lamp light rhythm control method

Abstract

The invention relates to a passenger car tail lamp and a passenger car tail lamp light rhythm control method. The passenger car rear tail lamp comprises a rear back door tail lamp and a side wall taillamp which are located at the position of a passenger car back door, and the side wall tail lamp and the rear back door tail lamp each comprise a rear position lamp. The tail lamp light rhythm control method comprises a tail lamp rhythm control strategy and unlocking and locking rhythm actions, the tail lamp rhythm control strategy is divided into a BCM control strategy and a tail lamp control strategy; and the unlocking and locking rhythm actions include three actions of rhythm, normally-on and gradually-off. According to the invention, when a user uses a vehicle to unlock and leaves the vehicle to lock; a vehicle controller BCM inputs a rhythm signal to the rear tail lamp; the rear tail lamp controls a plurality of light sources of the rear position lamp to be lightened according to thepreset lightening sequence, lightening time and lightening mode through a control circuit in the lamp, the lamplight rhythm effect is achieved, the ceremony feeling is brought to a user in the lamplight waving process, and the science and technology feeling and the distinguishing degree of the whole vehicle are improved.

Description

technical field [0001] The invention relates to a rear tail light of a passenger car and a light rhythm control method of the rear tail light of a passenger car. Background technique [0002] In the past, the rear taillights of passenger cars were mainly used to realize some common signal light functions such as brake lights and rear position lights. The internal control circuit can only control the LED light source of a certain function to turn on or off at the same time, and the lighting effect is relatively simple; When the vehicle is unlocked and when the vehicle is locked, the user is often reminded of the location of the vehicle and the state of the unlocked lock only by the blinking of the turn signal. [0003] With the development and innovation of lighting control technology, the internal control circuit has greater flexibility and diversity in the control of LED light sources, which can break the conventional lighting effect that can only be turned on or off at the...
