Novel rearview mirror control system

Abstract

The invention relates to a rearview mirror control system comprising a host machine and a slave machine. The slave machine is a rearview controller, the host machine is an automobile peripheral controller, and the slave machine and the host machine communicate through LIN. The slave control is mainly used for controlling the mirror surface of the rearview mirror by controlling a stepping motor anda transmission system, and comprises mirror surface folding, unfolding control and folding / unfolding functions; and an electric rearview mirror and an mirror surface adjuster can be controlled to beadjusted vertically / horizontally through linkage with a memory system (IMS). The novel rearview mirror controller is independently composed of LH / RH, and an MCU internal pull-down resistor of the rearview mirror controller is used and corresponds to two types of LH / RH. SPI communication is adopted for the host machine and the slave machine, and data packets are generated at a time. In addition, accurate control of stepping motor is realized; a data packet can be sent out at a time to control the stepping motor to operate according to the reversing state and data setting of the host, and various actions of the rearview mirror are completed.

Description

technical field [0001] The invention relates to a novel rearview mirror control system.

Modern Technology and Equipment 2013, 27 (7): 120- 126.[2] Ling Shiyun, Liu Hong, Tang Meiqi's design scheme that can enhance the safety of car reversing [J] Shandong Industrial Technology Information 2015,37(5):86-88.[3] Huang Gang's work on electric rearview mirrors and maintenance[J]. Times Agricultural Machinery 2019,32(17):75-77. But generally based on CAN bus, the structure is complex and the cost will be relatively high, so it cannot be used for simple transformation of existing vehicles
