Problems solved by technology

[0004] In the above-mentioned vehicle automatic driving system, the driving environment cannot be monitored through the camera and image recognition system to monitor the overall environment of the road section, and early prevention cannot be achieved, which greatly reduces the user's driving experience; in addition, because 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. Even if the driver can update it in time, the final data may not be able to reflect the current information because there is no latest information about the road in the existing resources. The current road conditions will eventually lead to unreasonable driving routes and low navigation accuracy, which will cause inconvenience to driving

Abstract

The invention discloses a vehicle automatic driving system for real-time update of road information. The system includes a vehicle control unit, a positioning system, an information transceiver, a steering-by-wire system and vehicle monitoring module. The vehicle control unit records a driving route through the positioning system, and exchanges information with an urban road monitoring center through information transmission and reception, corrects road information provided by the urban road monitoring center, records steering wheel actions through the steering-by-wire system, and corrects steering data through combination with the positioning system. When an automatic driving function is activated, vehicle control unit performs automatic driving control over the vehicle according to the road information of a selected road segment, the vehicle driving information monitored in real time by the vehicle monitoring module and the steering data. Through real-time data exchange between the vehicle control unit and the urban road monitoring center, the road information can be updated timely, navigation accuracy can be improved, occurrence of traffic violation incidents can be reduced substantially, and safety of vehicle driving can be ensured to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of vehicle automatic control, in particular to a vehicle automatic driving system with the function of updating road information in real time. Background technique [0002] With the increase of the number of vehicles 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 vehicle automatic driving systems. [0003] An existing vehicle automatic driving system 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 are based on information such as pre-stored road maps. Carry out navigation, plan a reasonable driving path between the current position of the vehicle and the destination, and guide the vehicle to the ...
