A method and system for improving the safety of vehicle-mounted display devices

Abstract

The invention relates to a method and system for improving using safety of vehicle-mounted display equipment. The method and system for improving using safety of the vehicle-mounted display equipment is characterized in that the vehicle running state and the vehicle equipment status are monitored in real time or in definite time, when a vehicle is backed up or a truck of the vehicle is in an opening status, displaying work of the vehicle-mounted display equipment is closed or stopped automatically. Therefore, the influence for safety of surrounding pedestrians or drivers due to direct light ray of equipment such as a light ray machine in the vehicle is avoided.

Description

technical field [0001] The invention relates to a vehicle-mounted intelligent system, in particular to a method and system for improving the safety of a vehicle-mounted display device. Background technique [0002] As a new type of mobile media, vehicle-mounted display equipment is more flexible than traditional rear window stickers. It can be in the form of projection, LED screen, LCD screen or LCD screen plus reflector. When it adopts the projection method, the entire rear window (the rear window is generally installed on the trunk door) is turned into a huge display screen, and the light is projected onto the glass to form an image, which is an active luminous display method. Since there is a projector installed in the car, the brightness of the projector is generally greater than 100lm in order to have a good imaging effect. a high security risk. When it adopts the form of LCD screen and reflector, its brightness may be higher, sometimes up to 1000cd / m 2 above. The d...

Problems solved by technology

[0004] Scenario 1: When a car passenger uses the trunk, the scene of opening the trunk door must be involved at this time. When the on-board display device is a projector, since the projector in the car directly projects the light to the rear window on the trunk door Glass, when the passenger opens the trunk door, the passenger will directly face the projection light source, and the high-brightness projection light source will cause damage to the eyes of the passenger; Passengers will also directly face the bright display screen, which will also cause damage to the eyes. This problem must be properly resolved;

[0005] Scenario 2: Due to the reflective characteristics of light, when the vehicle-mounted display device is a projector, the light projected by the projector in the car to the rear window glass will inevitably be reflected back into the car in addition to being transmitted and imaged outside the car. , and when the driver is reversing, the driver looks at the rear window glass. If the rear window glass still displays images at this time, then this will seriously interfere with the driver's reversing judgment, thereby causing driving safety; At the same time, the reflector will inevitably reflect part of the light to the driver's eyes, and this problem must also be properly resolved
