Embodiment Construction

[0024] The embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as a limitation of the present invention.

[0025] like figure 1 As shown, the vehicle-mounted light and small HUD head-up display system in this embodiment includes: electronic components, projection components and OBD modules. It is placed above the dashboard directly in front of the driver. like figure 2 As shown, the system is installed at the position between the top of the instrument panel directly in front of the driver and the windshield.

[0026] The electronic component can receive vehicle condition information and sensor information, and the GPU organizes to generate a picture, drives the image source in the projection component, and finally forms a head-up virtual image through the optical system of the projection component.

[0027] The electronic components include CPU, GPU ...

Abstract

The invention relates to a vehicle-mounted light-small head-up display (HUD) system. The overall device is composed of an electronic component, a projection component and an OBD module, wherein the electronic component can achieve interconnection with a smart phone in a wireless mode. An OBD communication interface reads vehicle condition information through a CAN bus on a vehicle and transmits the vehicle condition information to the electronic component through the Bluetooth. An electronic component CPU generates a picture through a GPU by combining sensor information with the vehicle condition information and drives an image source and an optical system in the projection component to achieve virtual imaging in the front head-up range of a driver, wherein the sensor information comprises GPS navigation information, camera information and e-dog information, the vehicle condition information comprises the vehicle speed, the revolving speed, the water temperature, oil consumption, braking system information and power system information, and the optical system is a light-small optical system composed of a baffle board, a diffuse reflection type imaging board and a meniscus spherical mirror. The head-up display (HUD) system has the advantages of being convenient to use and easy to install and can increase the driving security coefficient.

Description

technical field [0001] The invention relates to the field of vehicle augmented display (AR), in particular to a vehicle-mounted light and small HUD head-up display system. Background technique [0002] When the vehicle is driving at high speed, especially at night, the driver may look down at the instrument display or the navigation display on the center console. At this time, if there is an emergency ahead, it may be too late to take effective measures and cause an accident . Assuming that the vehicle is traveling at a speed of 120KM / H, even if the driver's line of sight is disturbed for 1 second, this means that there is a blind spot of 33 meters, which poses a major safety hazard. The vehicle head-up display system (HUD) can effectively avoid this situation. [0003] Vehicle-mounted head-up display system is an augmented reality vehicle-mounted display device, which is derived from aviation airborne head-up display technology. It uses an off-axis optical system to displ...
