Intelligent control device of electromotion rearview mirror of car

Abstract

The invention relates to an intelligent control device of automobile electric rear-vision mirror that comprises master control module, left rear-vision mirror driving module, right rear-vision mirror driving module. The intelligent control device possesses CAN bus interface which can blend with current CAN bus system, and the interface protocol with CAN bus can be changed to increase the flexibility and versatility greatly. The electric rear-vision mirror intelligent control device can adjust the angle of rear-vision mirror len automatically based on the bus signals of turning left, turning right, recovery in rectilinear path, driven backward, stopping driven backward sent by CAN bus, and eliminate the visual blind area of driver. The electric rear-vision mirror intelligent control device uses LIN bus to accomplish the control of electric rear-vision mirror, it decrease the cost.

Description

technical field [0001] The invention relates to an automobile rearview mirror control device, in particular to an intelligent control device for an electric rearview mirror. Background technique [0002] With the development of the automobile industry, automobile rearview mirrors are also updated. The purpose of the rearview mirror is to achieve the rearview range expected by the driver, but with the continuous improvement of people's quality of life, the purpose of the rearview mirror is not only that simple, but more consideration is given to its safety, convenience and comfort. sex, luxury.
