A smart car head-up display

Abstract

The invention discloses a vehicle head-up display which comprises a sight tracking device, a sensor message receiver, an information processing center and a projector. The sight tracking device is used for acquiring the sight position of a driver and transmitting the sight position to the information processing center, the sensor message receiver is used for acquiring pick-up information of a vehicle sensor and transmitting the pick-up information to the information processing center, the pick-up information includes position information representing a road condition in front of a vehicle, the information processing center is used for selecting the best projection position within the sight of the driver or on the periphery of the sight on a front vehicle windshield without hindering the driver from observing the road condition according to the sight position of the driver and the pick-up information of the vehicle sensor, and the projector projects the information to the front vehicle windshield according to the best projection position determined by the information processing center. The vehicle head-up display can automatically select the best projection position on the front vehicle windshield according to the sight of the driver and the condition outside the vehicle, so that the area of the projected information is increased without affecting the sight of the driver.

Description

technical field [0001] The invention relates to an automobile head-up display. Background technique [0002] When the car is running at high speed, especially at night, if the driver looks down at the instrument panel or operates the navigation on the center console and encounters an emergency ahead, it may cause a traffic accident because it is too late to take measures. [0003] In order to reduce the number and time of the driver's sight leaving the road ahead and expand the driver's field of vision, head-up displays have gradually been applied to cars. Head Up Display (HUD), referred to as HUD, is a comprehensive electronic display device composed of electronic components, display components, controllers, high-voltage power supplies, etc. It can pass the information required by the driver in the form of images and characters. The optics are projected onto the windshield of the car. When the driver observes the road conditions through the front windshield, he can see th...

Problems solved by technology

Since the information projected by the head-up display is located on the front windshield, in order not to affect the driver's sight, the traditional head-up display has a small projection area and the projection position is fixed in front of the driver, the amount of information provided is small, and the projected information is fixed.

Some researchers have proposed a full-area head-up display that can project information in a large area on the entire front windshield, but this kind of head-up display seriously affects the driver's sight, especially when driving at night
