Electronic assistance rear view system based on image communication

The present invention relates to an electronic assistance rear view system based on image communication. The electronic assistance rear view system is positioned on a motor vehicle and comprises a left side ultrasonic sensor, a right side ultrasonic sensor, a left side rear view camera, a right side rear view camera and an instrument panel controller; the left side ultrasonic sensor and the right side ultrasonic sensor are respectively positioned on the left side and the right side of the motor vehicle and are used for respectively detecting distances from a left vehicle body to an obstacle and from a right vehicle body to the obstacle; and the instrument panel controller is connected with the left side ultrasonic sensor, the right side ultrasonic sensor, the left side rear view camera and the right side rear view camera respectively, and determines whether to start the left side rear view camera and the right side rear view camera or not according to detection results of the left side ultrasonic sensor and the right side ultrasonic sensor. According to the electronic assistance rear view system, under the condition that passing spaces at the two sides of the motor vehicle are small, the left and right side rear view cameras are used to automatically replace a left rear view mirror and a right rear view mirror for rear view monitoring, and therefore the passing efficiency and the intelligence level of the motor vehicle are improved.
