Problems solved by technology

[0004] In the above autopilot system, since the road map is pre-stored in the vehicle, the update of its data depends on the manual operation of the driver, and the update frequency cannot be guaranteed. There is no latest information about roads in the resources, so the final data cannot reflect the current road conditions, which eventually leads to unreasonable driving routes and low navigation accuracy, which brings inconvenience to driving

Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0031] Such as figure 1 and combine figure 2 As shown, a vehicle automatic driving system, including lidar, position

[0032] set evaluator, camera and radar; the lidar is set on the top of the car body, and scans in all directions to obtain an accurate three-dimensional map of the car body environment; the position evaluator is set on the left rear wheel of the car body , used to accurately locate the location on the map; the camera is set next to the rearview mirror, which helps the on-board computer to identify sidewalks and bicycle obstacles; the radar is set around the car body to determine the distance between obstacles location of the object.

[0033] Further, it also includes a lane departure warning module, an automatic emergency brakin...

Abstract

The invention discloses an automatic vehicle driving system and a usage method therefor. The automatic vehicle driving system comprises a laser radar device, a position evaluation device, a camera andradar devices, wherein the laser radar device is arranged on a top part of a vehicle body and is used for scanning in all directions, an accurate three dimensional map about a vehicle body environment can be obtained, the position evaluation device is arranged on a left rear wheel of the vehicle body and is used for accurately positioning a position thereof on the map, the camera is arranged beside a rearview mirror and is used for helping a vehicle-mounted computer to identify side pavements and bicycle barriers, and the radar devices are arranged on a periphery of the vehicle body and are used for determining distance from the positions of the barriers. The beneficial effects of the automatic vehicle driving system and the usage method therefor disclosed in the invention are that due toreal time data interaction between the automatic vehicle driving system and an urban road center, road information can be timely updated, and navigation accuracy can be improved; peccancies such as overspeeding, jumping a red light and the like can be greatly reduced; probabilities of car accidents can be lowered; safety of a driver can be ensured to a certain degree.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a vehicle automatic driving system and a method for using the same. 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 autopilot 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...
