Method and system for regulating field angle of head-up display device

Abstract

The invention discloses a method and system for regulating the field angle of a head-up display device. The field angle of the head-up display device can be conveniently regulated without manual operation. The method includes the steps that an intelligent terminal sends a control instruction to an instruction processing device in a wireless communication mode according to a virtual direction key, pressed by a user of the head-up display device for a long time, of a man-machine interaction interface of the intelligent terminal; the instruction processing device sends a rotation instruction to a first stepping motor and / or a second stepping motor according to the control instruction; a reflection plate of the head-up display device is borne to rotate through the first stepping motor and / or the second stepping motor according to the rotation instruction. On one hand, troubles caused by wiring are eliminated, and the cost for designing physical keys and a controller of the physical keys is reduced; on the other hand, as long as the user feels that the field angle is not good, the angle does not need to be manually regulated like the mode in the prior art, the angle only needs to be regulated in situ, the user can conveniently use the head-up display device, and the flexibly of the head-up display device is enhanced.

Description

technical field [0001] The invention belongs to the field of automotive electronics, and in particular relates to a method and system for adjusting the viewing angle of a head-up display device. Background technique [0002] With the maturity of automobile manufacturing technology, more and more high-end vehicles are equipped with advanced automotive electronic products, and Head Up Display (HUD) is one of them. HUD is an automotive electronic product based on Augmented Reality (AR) technology. The so-called AR simply means superimposing computer-generated image information on the human field of vision to enhance human perception of the current environment. For example, an AR-based HUD can project images such as vehicle speed and navigation information on the windshield or a projection screen above the center console to assist the driver in driving the vehicle. [0003] For the use of HUD, the adjustment of the field of view is very critical, because only when the field of ...

Problems solved by technology

Although some HUDs have reflectors, they need to be adjusted manually, so it is difficult to quickly determine the amount of adjustment required for the best viewing angle
