AR-HUD-based automobile forward collision early warning detection system and method

Abstract

The invention discloses an AR-HUD-based automobile forward collision early warning detection system and method. The system comprises a detection unit used for obtaining the vehicle driving condition of a vehicle, a sensing unit, a processing unit and a display unit, wherein the vehicle driving condition comprises vehicle driving speed information and acceleration information; the sensing unit is used for acquiring longitudinal distance information and transverse distance information between a target vehicle or an environment obstacle in front of the vehicle and the vehicle, and speed information and acceleration information of the target vehicle; the processing unit is used for receiving the information acquired by the detection unit and the sensing unit in real time, calculating the distance impact time TTC of the target vehicle and sending out an alarm signal; and the display unit is used for generating a corresponding early warning picture from the alarm signal of the processing unit through the AR-HUD system, projecting the early warning picture to front windshield glass, and displaying the early warning picture, the environment and the traffic scene in an overlapping manner to assist in reminding a driver of the condition that the forward collision risk possibly exists. A displayed warning picture content can be combined with the environment and the traffic scene so that a driver can intuitively perceive the forward collision early warning information.

Description

technical field [0001] The present invention relates to intelligent driving technology, in particular to a vehicle forward collision warning detection system and method based on AR-HUD. Background technique [0002] With the traditional head-up display system, the driver can see important information projected on the windshield, which can help the driver observe emergency situations more safely and take timely actions without lowering his head or shifting his eyes. [0003] However, due to the small FOV of the display interface (field of view 6°*2°), the traditional head-up display system cannot cover the lane ahead, and the displayed content cannot be combined with the environment and traffic scenes, and can only support the display of forward collision warning. Simple icon information such as the detection system makes it difficult for the driver to detect and perceive the shape and color changes of the icon brought about by the relevant alarm information, and has a limite...

[0003] However, due to the small FOV of the display interface (field of view 6°*2°), the traditional head-up display system cannot cover the lane ahead, and the displayed content cannot be combined with the environment and traffic scenes, and can only support the display of forward collision warning. Simple icon information such as the detection system makes it difficult for the driver to detect and perceive the shape and color changes of the icon brought about by the relevant alarm information, and has a limited role in assisting driving.
