Internet of Vehicles remote intelligent vehicle locking function emergency unlocking control method

Abstract

The invention discloses an Internet of Vehicles remote intelligent vehicle locking function emergency unlocking control method, relates to the technical field of engine control, and solves the technical problem that existing emergency unlocking excessively depends on a terminal and a CAN network. The method comprises the following steps: S1, monitoring the operation state of a vehicle in real time, and if the operation state of the vehicle meets an emergency unlocking request, executing the step S2; S2, judging whether an emergency unlocking condition is met or not, if the emergency unlockingcondition is met, completing emergency unlocking, adding the number of continuous use times by one, adding the number of lifelong use times by one, starting to record the unlocking time; otherwise, failing the emergency unlocking and quitting; and S3, judging whether an emergency unlocking quitting condition is met or not; and if the emergency unlocking quitting condition is met, quitting the emergency unlocking state. Emergency unlocking is carried out by judging the operation state of the vehicle, and the problem that the vehicle is unstable due to the fact that the vehicle excessively depends on a terminal and a CAN network can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of engine control, more specifically, it relates to an emergency unlocking control method for a remote smart lock function of the Internet of Vehicles. Background technique [0002] The car locking function of the Internet of Vehicles has been widely used at present. This function is mainly used to control the vehicles purchased by loans. If the buyer fails to repay the loan, the dealer can remotely send instructions through the platform to restrict the operation of the engine, so as to limit the operation of the vehicle. Remind users of the purpose of repayment. The commands issued by the platform are received by the vehicle terminal and forwarded to the engine, and the engine executes after receiving the command. If the vehicle terminal is removed, the commands issued by the platform will not be transmitted to the engine. In order to deal with this situation, the engine has developed an anti-disman...

AI Technical Summary

Problems solved by technology

[0005] 1. Too much reliance on the terminal. If the terminal fails, the temporary unlock code cannot be input to the vehicle terminal, and the vehicle terminal cannot send an unlock request normally, so emergency unlocking will not be possible;

[0006] 2. Too much reliance on the CAN network, if the CAN network is disconnected or interfered, the unlock request sent by the vehicle terminal will not be transmitted to the engine, and emergency unlocking will not be possible; after the emergency unlock timeout, the vehicle terminal resends the lock command won't be able to pass to the engine, that won't be able to go back to lock

Therefore, the existing emergency unlocking function has the problem of insufficient stability
