Novel courtesy light control system

Abstract

The invention discloses a novel courtesy light control system, and belongs to the field of automotive lighting control. The novel courtesy light control system comprises a radio frequency signal processing module, a control module, a left/right headlight driving chipset and a pixel type LED headlight, and the radio frequency signal processing module and the control module are connected by a CAN bus. The control module is connected with the left/right headlamp driving chipset through a UART bus. The left/right headlight driving chipset is electrically connected to the pixel type LED headlight.An identifiable area of the radio frequency signal processing module is divided into coverage areas of LED beads in the pixel type LED headlight. Compared with a traditional courtesy light, the technical scheme has a more scientific and technological sense, an interactive function between human and car is increased, a feeling of "being noticed by the car" is given to owners, meanwhile, compared with a technical scheme of controlling a motor to enable the light spot to move, the novel courtesy light control system has the advantages of longer service life, higher response speed, lower cost andthe like.

Description

technical field [0001] The invention belongs to the field of vehicle light control, in particular to a novel welcome light control system. Background technique [0002] Today, as the popularity of cars is getting higher and higher, people are paying more and more attention to the lighting of their cars, and the most concerned thing is the welcome light. Nowadays, cars generally have their own welcome lights. In one case, when the owner opens the door or unlocks the vehicle, a light with a pattern or text is projected on the ground; in another case, when the owner approaches the car with a smart key, The car can actively "perceive" the arrival of the owner by sensing the smart key, and automatically turn on multiple lights such as headlights, taillights, rearview mirror floor lights, inner door handle lights and interior lights through the control components, so as to achieve the goal of welcoming guests. The atmosphere gives car owners more sense of dignity. [0003] Howev...
