Method and system for realizing remote diagnosis and controlling vehicle

Abstract

The invention discloses a method and system for realizing remote diagnosis and controlling a vehicle. The method comprises the steps that S1, a vehicle-mounted terminal obtains real-time data on the vehicle through a vehicle body CAN bus; S2, the vehicle-mounted terminal sends the data to roadside communication equipment in a wireless transmission mode; S3, the roadside communication equipment uploads the data to a server; S4, the server performs operation on the data and judges whether the data is abnormal or not, if yes, the step S5 is executed, and if not, the step S6 is executed; S5, the server issues a command to the roadside communication equipment, the roadside communication equipment sends the received command to the vehicle-mounted terminal, and the vehicle-mounted terminal sendsa control command through the vehicle body CAN bus; and S6, the server feeds back abnormal-free data to the roadside communication equipment and then turns to the vehicle-mounted terminal. According to the invention, data interaction between the roadside communication equipment and the vehicle-mounted terminal is carried out by using wireless transmission modes such as LTE-V2X and the like, diagnosis and real-time control of a remote vehicle are realized, and the communication stability is improved.

Description

technical field [0001] The invention relates to the technical field of remote vehicle Internet, in particular to a method and system for realizing remote diagnosis and controlling a vehicle. Background technique [0002] The vehicle-mounted terminal (Tbox) is installed on the existing vehicle-mounted system to realize the interaction of vehicle information with the remote Internet of Vehicles server, including the uploading of vehicle real-time operation data and the issuance of server-controlled vehicle commands. The existing networks used by the vehicle terminal (Tbox) include 2G (GSM), 3G (CDMA), and 4G (TD-LTE and FDD-LTE). The vehicle-mounted terminal (Tbox) sends data to the remote Internet of Vehicles server at a certain time interval, and processes the relevant data on the server. If the vehicle is found to be abnormal, such as the trajectory is quite different from the scheduled driving route, the battery is almost exhausted, the motor When the data is abnormal, re...

Problems solved by technology

[0003] However, when the vehicle-mounted terminal (Tbox) needs to communicate with the cloud-based Internet of Vehicles server through the vehicle-mounted terminal (Tbox), the existing communication method will bring a huge delay, especially when the network is congested, information may appear In the case of failure to transmit, the control command is delayed or even lost, resulting in the inability to realize the control of the vehicle, that is, the real-time performance is not strong

The real-time data of the car body collected by the vehicle terminal (Tbox) may not be sent to the cloud server when the network is congested, resulting in the cloud server having no corresponding real-time data for calculation and logical judgment
