Head-up display device

Abstract

The invention discloses a head-up display device. The head-up display device comprises a host machine, a display device, a curved-surface semi-transparent reflecting screen, a voice interaction unit and a driver detection device, wherein the host machine is used for transmitting an image signal to the display device, the display device is arranged at one side of the host machine and used for displaying the image signal, the curved-surface semi-transparent reflecting screen is used for receiving an image displayed by the display device and displaying the image after ghosting is removed, the image is displayed at the other side by penetrating the semi-transparent reflecting screen at one side of the host machine, the voice interaction unit is arranged in the host machine in advance, and the driver detection device is arranged in the host machine. The invention provides an intelligent vehicle-mounted device which supports whole-course voice interaction, monitors a driver in real time, gives an alarming in advance and has a good display effect, and the defects that a head-up display device is lack of voice interaction operation, is inconvenient to be placed in a vehicle and is lack of special driving emotion analysis in the prior art are overcome.

Description

technical field [0001] The invention relates to a vehicle-mounted intelligent device, in particular to a head-up display device. Background technique [0002] HUD (Head Up Display) is a flight aid commonly used in aircraft. Heads up means that the pilot does not need to look down to see the important information he needs. [0003] At present, the head-up display HUD also has the following defects: [0004] 1. Most of them can only display information such as vehicle speed and fuel level, and have no operating functions at all. [0005] 2. Insufficient in the principle of realization, generally by projecting vehicle-related information on glass and coated lenses (optical mirrors), and then balancing and reflecting it into the driver's eyes. [0006] 3. In terms of display methods, a projector based on the LED principle is generally used for projection, and the image is displayed on the imaging film, and the driver can see the relevant information of the vehicle through the...

Problems solved by technology

[0004] 1. Most of them can only display information such as vehicle speed and fuel level, and have no operating functions at all

[0005] 2. Insufficient in the implementation principle, generally by projecting vehicle-related information on glass and coated lenses (optical mirrors), and then balancing and reflecting into the driver's eyes

In addition, the use of a projector will be limited by the imaging distance, which will affect the overall appearance of the HUD device

[0007] 4. The information displayed on the HUD head-up display may be unclear, especially in the case of strong light in front, and there may be ghosting of the image, which will affect the driver's driving

[0008] 5. The imaging distance of the HUD is not far enough to be placed in the car, and the focal length does not match the driving scene, which cannot solve the problem of far-near fusion of the road surface and the instrument panel
