Description

In-car electronic rear view system

The present invention relates to an electronic auxiliary system, and more particularly, to an in-vehicle electronic rear-view system that can display the outside view through an in-vehicle electronic display screen.

With the high frequency of commercial activities and the rapid expansion and development of transportation and logistics, people rely more and more on mobile vehicles such as automobiles and motorcycles. At the same time, drivers are paying more and more attention to the protection of their own life and property while driving. Generally, in addition to considering In addition to the performance of the mobile vehicle and the comfort of riding, it will also be considered whether the mobile vehicle to be purchased provides sufficient safety protection devices or auxiliary devices. Under this trend, in order to increase the safety of driving, automobile manufacturers or vehicle equipment designers have developed various driving safety protection devices or auxiliary devices, such as rear-view mirrors and surround images that can instantly display objects in the dead-end area of the vehicle. Wait.

Taking traditional rearview mirrors as an example, drivers mostly use them to observe and determine whether there is an object outside the car when changing lanes or turning. For example, when driving at night, in a dark environment, the pupil of the driver's eye is just like the shutter of a camera, in a state of opening, in order to provide more light signals from the optic nerve. In this state, the driver's eyes are extremely sensitive to sudden bright light. Usually, the headlights from the overtaking or following vehicles reflected by the rearview mirror of the car will cause the driver to have visual dizziness, which will cause the driver's visual ability to decrease rapidly in an instant, thus increasing the driver's perception of obstacles ahead. The reaction time when it becomes visible.

In addition, based on the structural design of traditional automobiles, all rear-view mirrors have inherent blind spots in their installation positions, so that drivers cannot fully obtain the actual external environment of the car through the pictures provided by those rear-view mirrors. road conditions, and in terms of safety design considerations, there are still deficiencies to be improved.

Furthermore, when the driver wants to change lanes, turn or reverse during driving, the driver must change the line of sight to look at the left rearview mirror or the right rearview mirror, so as to actually understand the road environment of the one-lane lane. However, relying only on the visual area provided by the left or right rearview mirror cannot help the driver to understand the blind spot information that cannot be displayed by the left or right rearview mirror, and sometimes the driver needs to turn his head to check. The external and rear conditions of the vehicle, or with the interior rearview mirror, can fully obtain the static and dynamic scene outside the vehicle. Therefore, the above-mentioned specific actions for driving a vehicle all require the driver to constantly change their sight to obtain road condition information, and cannot timely pay attention to the road conditions in all directions, which may easily lead to a car accident or collision.

The present invention provides an in-vehicle electronic rear view system, thereby improving driving safety and reducing the probability of accidents caused by blind spots of sight.
