Abstract
Vehicle rear vision system formed by exterior mirrors and wide-angle lens plays a significant roll in the vehicle safety system. Existing vehicle rear view mirror system still has many problems unsolved, such as blind space during vehicle steering. This paper proposes a new design of intelligent vehicle rear vision system which can automatically adjust the angle of exterior vehicle mirrors in two dimensions in different driving conditions. The affecting factures includes vehicle steering angle, driving speed, and vehicle size parameters. The design uses an AT90C516RD + microcontroller as core control unit. The system adds a new automatic mode with existing manual functions remained. Upon theoretical simulation and model testing, the design has been proved to be fully functional and accepted by customer investigation with industrial potential.
