Problems solved by technology

However, this method is based on the transmission of network messages. When the car is locked and the network is disconnected, even if the financial vehicle fee has been paid, the vehicle cannot be started normally, and it will also affect the remote management of the vehicle by the management platform. and control

Embodiment 1

[0052] The financial vehicle was remotely locked due to overdue loan repayment, and the vehicle engine was restricted from starting. Pre-stored in the EEPROM of the vehicle ECU: limited start threshold = 3 times, self-inspection time threshold = 1s, and the initial default value of the number of times allowed for temporary unlocking = 3 times.

[0053] When the owner tries to start the vehicle, the engine fails to start due to the remote lock function. Every time the engine fails to start due to the remote lock function, the vehicle ECU will limit the number of starts Lock_tFail to 1 and store it in EEPROM. After the engine fails to start, the owner can trigger the temporary unlocking function by long pressing the vehicle start button for 5s.

[0054] The vehicle ECU sends a network confirmation request to the vehicle terminal in the form of a message through the CAN harness. The message of the network confirmation request is Fin_NW (0CFF44FD), and the first byte in the messag...

Abstract

The invention discloses a network-free temporary unlocking method for a remote financial locked car, comprising steps: 1. When the financial vehicle is locked remotely, the ECU of the vehicle judges whether the triggering condition for temporary unlocking is met when starting up, and if so, execute step 2; if not, Keep the car locked; 2. Trigger the temporary unlocking function, and the vehicle ECU sends a network confirmation request to the vehicle terminal; 3. The vehicle terminal self-checks the network status. If the network is disconnected, perform step 4. If the network is normal, keep the car locked; 4 . The ECU of the vehicle judges whether the allowed number of times of temporary unlocking is greater than 0. If yes, execute step 5. If not, keep the car locked; 5. Allow the financial vehicle to be temporarily unlocked, and start the engine. The invention can allow the financial vehicle to be temporarily unlocked in the state of no network, so that the financial vehicle can drive to the area covered by the network, so as to facilitate the remote management of the financial vehicle by the management platform.

Description

technical field [0001] The invention relates to a remote locking method of a financial vehicle, in particular to a network-free temporary unlocking method of a remote financial locked vehicle. Background technique [0002] With the development of the times, loaned vehicles and leased vehicles have become a new mode of vehicle use. However, since financial vehicles such as loaned vehicles and leased vehicles do not completely belong to the owner, the management platform needs to adopt GPS positioning, mandatory car locks, etc. to monitor financial vehicles. Carry out remote control to avoid car owners defaulting on necessary expenses such as loans and lease payments, thereby ensuring the safety of funds. [0003] At present, the application of remote locking technology has been relatively popular. The vehicle terminal installed on the vehicle communicates with the vehicle ECU (Electronic Control Unit, that is, the electronic control unit) and the management platform, and can ...
