Problems solved by technology

But even so, when the equipment is damaged or the transmission signal is affected, it will have an unpredictable impact on the remote driving function
Improving the algorithm of the software can reduce the transmission delay to a certain extent, and can also improve the accuracy of the data. However, if the received data is severely distorted or lost, it will also cause vehicle driving hazards. Unable to successfully transfer to vehicle

Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] The present invention proposes a remote driving vehicle control information transmission and processing method, and the specific steps are described in detail as follows:

[0034] Step 1: Remote cockpit sends command data

[0035] The remote cockpit will send a byte stream data B with a period of 20ms that carries the absolute value control information instruction set, which contains: the time stamp of the current time of the remote control cabin), steering angle (unit: degree, value range: -540 —540 degrees), vehicle speed (unit: km / h, value range: 0-30km / h), gear position (00: N gear, 01: D gear, 02: R gear), handbrake (00: no action, 01: Pull up, 02: Release, 03: Brake during travel), door (01: open, 02: close), turn signal (01: open, 02: close), headlight (01: open, 02: close ), whistle (01: on, 02: off), air conditioner (01: on, 02: off)...

Abstract

The invention discloses a remote driving vehicle control information transmission and processing method. During remote driving, two 4G routers are used for controlling vehicle information transmissionand processing through two different networks. The driving control server uses two 4G wireless routers to transmit and process control command information through a command double-transmission methodof two different 4G networks, when the vehicle-mounted terminal receives data, data selective combination is performed, and the latest data compared with the current time is selected from the two pieces of data. Therefore, when the network control information transmission and processing of one 4G wireless router goes wrong, the other 4G wireless router transmits and processes the control information through the other network, the information transmission and processing are stably controlled in real time, the stability of the control information transmission and processing is guaranteed, and an emergency mechanism that one transmission device is damaged is realized. According to the method, the real-time performance and the stability of transmission and processing of the vehicle control information are guaranteed to a great extent.

Description

technical field [0001] The invention discloses a remote driving vehicle control information transmission and processing method, which belongs to the technical field of remote control of intelligent vehicles. Background technique [0002] At this stage, when driving remotely, the command control information sent by the driver in the remote cockpit is sent to the on-board industrial computer through the driving control server. Therefore, a 4G wireless router is usually used on the vehicle side to receive remote control commands through a 4G network. . During this process, network equipment failures (such as server damage and failures, etc.), limitations of the wireless propagation environment (such as large building blocks, thunderstorms, etc.) may occur. And the position and speed of the vehicle change in real time, which may cause the channel environment to change, which will cause the channel characteristics to change randomly over time, and the received signal will be mor...
