Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] The criterion adopted in the present invention is: use a longer focal length lens to judge vehicles with an interval of more than 160M, this is a safe interval, the warning sign is a green light, and it is an early warning area when it reaches 100M, and the warning sign is a yellow light or a longer interval. When the interval is about 30M, it is an emergency alarm area. At this time, the warning sign is a red light or the sound of a short interval. The warning light can be a flashing light. The invention helps to reduce the incidence of rear-end collision accidents, and does not require the vehicle in front to transmit digital signals. When the safe speed is increased to the maximum speed allowed by the road, the yellow light is on, a...

Abstract

The invention discloses an automobile safety distance detection and safety control method. An optical imaging visual angle measuring method or a laser infrared method is adopted in front of an automobile for measuring and judging a distance between automobiles, and during optical imaging, a safe signal or an alert signal is given through the correspondence between the size of an image on an imaging target surface and a distance or a direct distance reading. A safety control device is formed by combining a device which adopts an optical imaging visual angle measuring device or a laser infrared device and a reversing radar to measure the distance between the automobiles, a silence, long rhythm sound and short rhythm sound indicating device as well as a green light, yellow light and red light indicating circuit; the potential of test data is inputted to a photoacoustic drive circuit of transistors; and a red light, a yellow light and a green light as well as a sounder are connected to the output of the drive circuit. According to the automobile safety distance detection and safety control method disclosed by the invention, a traffic light system is formed in the automobile through the combination of a measurement and automatic control technology and a visual prompt as well as an alarming method, a safety device is also formed in the automobile, and the automobile safety distance detection and safety control method and the safety control device integrate simplicity, visualization and habits.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle safety performance detection, and in particular relates to a vehicle safety distance detection and safety control method. The invention relates to a safety distance detection and safety control method and device for automobiles, in particular to a safety distance detection and control method and device for ensuring safety when automobiles are driving on expressways, and is referred to as a "traffic light" system in a vehicle for short. Background technique [0002] With the development of highways and the increase of car users, the safety requirements of cars are getting higher and higher. Vehicle speed, safety distance, and driver's state are the main hidden dangers of automobile accidents. How to ensure the safe distance between vehicles or obstacles during high-speed driving, slow down and stop in time are effective measures to reduce traffic accidents. There are 0-200m safe distance sig...
