Embodiment Construction

[0080] Such as figure 1As shown, the rudder and barcode reading equipment, reflective counting equipment, directional receiving antenna and receiver are installed on the front of the car, and the directional transmitting antenna and transmitter are installed on the rear of the car, plus electronic odometer, on-board computer and The control program, the automatic driving actuator and the rail track constitute the automatic driving system of the present invention.

[0081] Such as figure 2 As shown, select a lane on the highway (such as: the lane near the median strip 1) as the automatic driving lane, bury a concave guide rail 2 in the middle of the lane, and set up a reinforced concrete divider 3 and an emergency lane between the automatic driving lane and the ordinary lane. Exit 4, and there are normal entrances and exits; a section of reflector tape 6 is horizontally inlaid at every fixed distance on the driveway as a position coordinate confirmation point. The positions ...

Abstract

An automatic driving system of automobile is prepared as using steering wheel jack catch set on automobile to check automobile in concave track on express way to lead driving direction of automobile, using bar code reading device and light reflection counting device to obtain coordinate of lanes position coordinate confirmation point for revising coordinate indication on electronic mileage meter, using radio transmission device to send real time position coordinate data to follow - up vehicles, using vehicle computer to calculate out distance between vehicles and driving speed for each vehicle for working out driving decision executed by execution device.

Description

technical field [0001] The invention relates to automobiles and roads, and belongs to the field of automatic driving of automobiles. Background technique [0002] In recent years, countries around the world have invested a lot of manpower and material resources in the development of autopilot systems. [0003] Japan developed a test car with automatic driving function in 1995. The method is: a navigation magnet line is buried in the center of the road surface, the car drives according to the magnet line, the body is equipped with obstacle detection radar, and then equipped with electronically controlled accelerator and electronic brake. devices, etc., so as to carry out automatic driving. [0004] The automated vehicle road system in the United States is trying to use the Internet to input road information to the car, and then cooperate with the satellite positioning system to assist the car to drive according to the established route, hoping to finally achieve the purpose ...
