Vehicle-mounted electronic rearview mirror head-up displaying device

Abstract

The invention relates to vehicle-mounted electronic systems, and discloses a vehicle-mounted electronic rearview mirror head-up displaying device. The vehicle-mounted electronic rearview mirror head-up displaying device comprises a first camera, a second camera, a third camera, an image processor, a projection device connected with the image processor and a front windshield. The first camera, the second camera and the third camera are configured with A / D converters respectively, and the A / D converters on the first camera, the second camera and the third camera are connected with the image processor. Traditional inner and outer rearview mirrors are replaced with the cameras, collected image information is imaged right in front of a driver, the driver can conveniently monitor view fields behind and on the two sides of a vehicle under the right view condition, reaction time is shortened in the back up and lane changing process, and traffic accidents are reduced. The cameras are all small, exquisite and easy to arrange, and the drag coefficient and orthographic projection area of the whole vehicle are reduced. The shooting range is greatly widened, and the view blind area is lowered. Percentile position adjustment caused by different human bodies can be avoided.

Description

technical field [0001] The invention relates to a vehicle-mounted electronic system, in particular to a head-up display device for a vehicle-mounted electronic rearview mirror. Background technique [0002] At present, when the driver is driving, the situation behind the car is usually observed by the rearview mirror arranged outside the car, but the traditional rearview mirror can only monitor the vision of the left and right rear of the car, and the rear of the car Because it is blocked by the car, it cannot be observed, there are many blind spots in the field of vision, and the driving safety is low; and it is inconvenient to shake the head to observe every time when observing, especially in the process of reversing and changing lanes, which prolongs the reaction time; setting Rearview mirror, the volume of the rearview mirror is large, the drag coefficient of the vehicle and the area of ​​the front projection are large, and the energy loss is large; the traditional rearv...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the disadvantages of many blind spots in the field of vision, inconvenient observation, long reaction time, relatively large energy loss of the rearview mirror, and the need to adjust the position due to different percentiles of the human body in the prior art, and provides a This can reduce the blind area of ​​vision, improve the reaction time in the process of reversing and changing lanes, reduce traffic accidents, the camera is small and easy to arrange, reduces the drag coefficient and front projection area of ​​the vehicle, reduces the weight of the vehicle, and can avoid the difference caused by the human body. Adjust the position of the percentile, the head-up display device of the vehicle electronic rearview mirror that can be observed by both the main driver and the co-driver
