Mobile intelligent terminal based vehicle-mounted multimedia HUD (head up display) device

Abstract

The invention relates to a vehicle head up display device, in particular to a mobile intelligent terminal based vehicle-mounted multimedia HUD (head up display) device. The device comprises a projector, a HUD terminal and an OBD (on-board diagnostics) interface; the projector is used for projecting images to a front windshield of a vehicle, the HUD terminal is connected with the input end of the projector, and the HUD terminal is connected with the OBD interface through a data line and is connected with the mobile intelligent terminal through Bluetooth; the mobile intelligent terminal is provided with a Bluetooth communication module, a local database and an application software operation mechanism. By the application of high data processing and storing capabilities of mobile intelligent terminal equipment, vehicle condition alarm projection prompt, emergency self-help and intelligent traffic management functions can be provided, the applicable vehicle models can be selected through software, and display modes of types of display information can be set. The device is widely applicable, convenient to use and good in user's experience.

Description

Technical field [0001] The invention relates to a vehicle head-up display device, in particular to a vehicle multimedia HUD device based on a mobile intelligent terminal. Background technique [0002] Head Up Display, abbreviated as HUD, is also called a head-up display device, which is currently a flight aid instrument commonly used on aircraft. Head-up means that the pilot can see the important information he needs without having to lower his head. Head-up displays first appeared on military aircraft, reducing the frequency with which pilots need to look down at the instruments, avoiding interruption of attention and loss of state awareness. Because of the convenience of HUD and its ability to improve flight safety, civil aircraft have also followed up and installed. HUD uses the principle of optical reflection to project important flight-related information on a piece of glass. This piece of glass is located at the front of the cockpit, and the height is roughly level with ...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned various vehicle-mounted HUDs have a single function, and cannot realize the display of more safety warnings and prompt information, let alone realize intelligent traffic management; in addition, because the technical standards of different models are not uniform, the various information codes generated by the vehicle OBD interface are locked. The meaning has its own standards. These car HUDs can only be applied to one type of vehicle, but cannot be applied to all types of vehicles, and it is impossible to independently set the type of display information and the display method according to the needs of users.
