Description

Apparatus and method for controlling image display of vehicle {APPARATUS AND METHDO FOR CONTORLLING IMAGE DISPLAY OF VEHICLE}

The present invention relates to an apparatus and method for controlling image display of a vehicle.

In general, while driving, the driver looks ahead through the windshield and can check the rear without turning his head through the rear-view mirror on the vehicle body. Side rearview mirrors are installed on both left and right sides of the vehicle to view the left and right sides. We check with the naked eye to ensure safe operation.

However, when looking forward through the windshield or rearward through the rearview mirror from the driver's seat, an invisible blind spot occurs. Also, when looking at the left and right sides of the vehicle through the side rearview mirror, an invisible blind spot occurs. Safety accidents occur frequently due to this.

Therefore, recently, an increasing number of vehicles are installing blind spot detection devices on the front and rear of the vehicle so that drivers can conveniently check blind spots while driving. These blind spot check devices use cameras to record images from the front and rear. A common system is to allow the driver to view the captured image through a display inside the vehicle.

Recently, a technology has been proposed to display images captured by the rear camera by adding a display unit to one side of the rear-view mirror in the vehicle. However, this also only provides the function of displaying images around the vehicle, so it is not a function suitable for the future autonomous driving era. In order to provide this to drivers, groundbreaking technological development is required.

The present invention integrates a foldable display with the rear-view mirror to provide the driver with information around the vehicle, as well as provide information to drivers or pedestrians outside, and when unfolded, provides a large screen to the driver. The purpose is to provide a display control device and method.

Additionally, the control unit folds the display unit when the vehicle is in a normal driving mode.

And, when the display unit is folded, the control unit controls to output different images to the first display area and the second display area, respectively.

Additionally, the control unit controls to display at least one of a front image, a side image, and a rear image of the vehicle in the first display area.

In addition, the control unit controls to output a message according to at least one of the external state of the vehicle and the driving and parking state of the vehicle on the second display area.

And, the first display area faces the interior of the vehicle when the display unit is folded.

And, the second display area faces the outside of the vehicle when the display unit is folded.

And, when the vehicle is in autonomous driving mode, the control unit unfolds the display unit.

And, when the display unit is unfolded, the control unit positions the first display area and the second display area in a straight line, and displays one image in the first display area and the second display area. Control to output.

And, the display unit is implemented in the form of a room mirror.
