Problems solved by technology

Therefore, ordinary GPS cannot meet the application under high-speed and high-acceleration conditions. In addition to low positioning frequency, the phase-locked loop will also lose lock, and the pseudo-random code cannot be tracked.
[0003] In addition, the use of GPS navigation also has the problem of low positioning accuracy and the problem of not being able to receive signals in underground tunnels

Abstract

The invention relates to an automatic automobile driving method. The automatic automobile driving method is characterized by comprising an information code which is generated along a ground advancingdirection of a driving route, a sensing unit which acquires the information code along the ground advancing direction of the driving route on an automobile, and a control unit which controls driving of the automobile according to the information code that is acquired by the sensing unit and is generated along the ground advancing direction of the driving route, wherein the control unit controls driving of the automobile according to the information code which is acquired by the sensing unit and is generated along the ground advancing direction of the driving route. The automatic automobile driving method can realize full-automatic automobile driving on the conditions of high speed, high precision and no GPS navigation signal.

Description

technical field [0001] The invention relates to a method for automatic driving of a car. Background technique [0002] Existing car driving, especially car unmanned driving, is completed through high-precision GPS positioning and navigation plus sensing and detection technology. The highest frequency of civilian GPS positioning is generally 10Hz, but the measurement frequency of pseudo-random codes can reach 100Hz. Therefore, ordinary GPS cannot meet the application under high-speed and high-acceleration conditions. In addition to low positioning frequency, the phase-locked loop will also lose lock, and the pseudo-random code cannot be tracked. [0003] In addition, the use of GPS navigation also has the problem of low positioning accuracy and the problem of not being able to receive signals in underground tunnels. Contents of the invention [0004] The purpose of the present invention is to provide a method for automatic driving of automobiles, so as to realize fully au...
