AI Technical Summary
Technical Problem
Due to the serial uploading characteristics of the MQTT protocol, on-board terminals are prone to traffic jams when processing multiple services, resulting in some services being unable to be executed in time and resulting in missing functions.
Method used
After sending remote control instructions on the user side, the vehicle status data is retrieved from the cloud after a certain period of delay is delayed in the order of the received execution results, ensuring that the data is the latest state.
Benefits of technology
It effectively avoids business processing problems caused by interface blockage, ensures that the vehicle status data displayed on the user side is up-to-date, and improves the reliability of the system.

Abstract
The invention discloses a vehicle state control system and method and a vehicle. The system comprises a user side, a vehicle-mounted terminal and a cloud side, and the vehicle-mounted terminal and the user side are both in communication connection with the cloud side; the user side is used for sending one or more remote control instructions to the vehicle-mounted terminal; the vehicle-mounted terminal is used for executing the remote control instructions according to the sequence of the received remote control instructions so as to control the vehicle to carry out operation corresponding to the remote control instructions, uploading execution results of the remote control instructions to the cloud after each remote control instruction is executed, and obtaining current state data of the vehicle and uploading the current state data to the cloud after all the remote control instructions are executed; wherein the execution result is used for reflecting whether the vehicle completes operation corresponding to the remote control instruction or not, and the state data is used for reflecting the current state of the vehicle; the cloud side is used for feeding back the execution result received each time to the user side, and when the user side receives one execution result each time, the state data are called from the cloud side after the preset duration of receiving the execution result and are displayed. By adopting the system, the uploading sequence of the vehicle-mounted terminal is optimized, the efficiency is improved, and the problem of real-time synchronization of the vehicle state can be effectively solved.
