Remote driving system and method based on 4G network communication

Abstract

The invention discloses a remote driving system and method based on 4G network communication. The remote driving system comprises a simulator part and a vehicle terminal part, wherein the simulator part comprises a steering wheel and an accelerator brake pedal, and is connected with a control room host through a serial port to simulate real driving and acquire a control signal; the vehicle terminal part adopts a STM32 single-chip microcomputer; two GPIO pins of PA9 and PA10 are led out to serve as serial ports I which are connected to an industrial control computer of a vehicle through a USB;two GPIO pins of PA2 and PA3 are led out to serve as serial ports II which are connected to a 4G module; and when a simulator in a remote cockpit generates a control signal, the signal is transmittedto the STM32 single-chip microcomputer through a serial port, transmitted to the 4G module through a cloud end, and transmitted to the single-chip microcomputer through the serial ports II, and data is controlled in a CAN protocol format to be transmitted to the industrial control computer through the serial port I to control vehicle running. The remote driving system and method have the advantages of moderate technical requirements, wide coverage of 4G signal and relatively low development cost.

Description

technical field [0001] The present invention relates to a remote driving system, more specifically to a remote driving system and method based on 4G network communication. Background technique [0002] Self-driving car, also known as unmanned car, computer-driven car, or wheeled mobile robot, is a kind of intelligent car that realizes unmanned driving through a computer system. [0003] The communication module has three transmission modes: buffer transfer mode (Buffer Access Mode), transparent transfer mode (Transparent Access Mode), and direct push mode (Direct Push Mode). Due to the Buffer Access Mode, the communication module will not Active upload requires the host to use AT commands to query, the real-time performance is greatly reduced, and the expected requirements cannot be met; in Transparent Access Mode, once the connection is established, sending AT commands to the communication module will be defaulted as the data to be sent, and the connection will be disconnec...

AI Technical Summary

Problems solved by technology

[0008] Although both technical solutions A and B can achieve unmanned driving very well, solution A requires multiple sensors at the hardware level, and the development cost is very high. From the software level, the development algorithm is very complex, and the skills of technical personnel are required. higher

Plan B adopts the fifth-generation mobile communication network. 5G technology is still in the research process, and there is still some time before commercial use. 5G signal coverage is not complete, and the development of infrastructure requires high costs.
