Abstract

The invention discloses an automobile autopilot system comprising an automobile control unit, a positioning system, an information transmit-receive unit and a steering-by-wire system; wherein the automobile control unit is used for recording driving routes by the positioning system, for exchanging information between the automobile autopilot system and urban road monitoring center by the information transmit-receive unit, for correcting road information provided by urban road monitoring center, for recording the movement of steering wheels by the steering-by-wire system, and for correcting steering data by combining the positioning function of the positioning system. When the autopilot function is activated, the automobile control unit is used for automobile automatic piloting control according to road information, traffic report and steering data of a selected section of road. Real-time data interchange between the automobile autopilot system and urban road monitoring center is provided, so that road information can be updated timely; navigation accuracy is increased; traffic violations such as speeding, running red lights are decreased; car accident rate is decreased, and the safety of drivers is ensured in a certain level.

Description

technical field [0001] The invention relates to automatic control technology of automobiles, in particular to an automatic driving system of automobiles. Background technique [0002] With the increase of the number of cars in our country, road traffic congestion is becoming more and more serious, and the annual traffic accidents are also rising. In order to better solve this problem, it is necessary to research and develop auto-driving systems. [0003] An existing auto-driving system for a vehicle uses a camera installed in the driver's cab and an image recognition system to identify the driving environment, and then the vehicle's main control computer, GPS positioning system, and path planning software provide information on the vehicle based on pre-stored road maps and other information. Carry out navigation, plan a reasonable driving path between the current position of the vehicle and the destination, and guide the vehicle to the destination. [0004] In the above aut...
