Back-up image system with camera adjustable in angle

Abstract

The invention relates to the technical field of automobile electronics and provides a back-up image system with a camera adjustable in angle. The back-up image system mainly comprises a back-up imagecontrol unit, a steering wheel rotating angle sensor, a speed sensor, a gradient sensor, a horizontal adjusting motor, a vertical adjusting motor, a transmission device, the camera, a control panel and a display unit. The back-up image control unit can automatically adjust the heading angle and pitch angle of the camera according to signals detected by the steering wheel rotating angle sensor, thespeed sensor and the gradient sensor, and the heading angle and the pitch angle can also be adjusted manually through the control panel. According to the system, the angle of the camera can be adjusted automatically or manually, a visual blind area of the inner side of a curve during back-up and steering can be reduced, the viewing range of the camera when a car backs up to climb a slope can be enlarged, and the back-up safety is improved. Meanwhile, under a special condition, the system can also be used for observing the scene behind the car and is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a reversing image system with an adjustable camera angle. Background technique [0002] Reversing image is a common reversing assistance system. When the vehicle is in reverse gear, the reversing image system will automatically connect to the camera and display the rear image information collected by the camera on the display screen, which is convenient for the driver to observe and grasp. Rear traffic. As an important part of the reversing imaging system, the camera is usually fixedly installed in the center of the rear of the vehicle, facing the rear of the vehicle, and its angle cannot be adjusted; when the vehicle is reversing to the rear, the viewing range of the camera can meet the requirements. When turning, the driver often pays more attention to the scene behind the vehicle, which will create a blind spot on the inside of the curve; at the same time, when...

Problems solved by technology

As an important part of the reversing imaging system, the camera is usually fixedly installed in the center of the rear of the vehicle, facing the rear of the vehicle, and its angle cannot be adjusted; when the vehicle is reversing to the rear, the viewing range of the camera can meet the requirements. When turning, the driver often pays more attention to the scene behind the vehicle, which will create a blind spot on the inside of the curve; at the same time, when the vehicle reverses uphill, the camera’s viewing range will be reduced due to the slope, so there will be a big problem. security risks

[0003] In the existing patent application number 201220366172.7, an angle-adjustable reversing camera device is disclosed, which can judge the turning direction of the car when reversing according to the output signal of the steering wheel angle sensor, and automatically adjust the direction of the reversing camera through the horizontal adjustment motor. The heading angle (the angle between the projection of the optical axis of the reversing camera on the horizontal plane and the longitudinal axis of the car), but the automatic adjustment of the pitch angle of the reversing camera (the angle between the optical axis of the reversing camera and the horizontal plane) cannot be realized

In addition, the existing reversing camera system is only used when reversing, and has a single function, which needs to be further developed
