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 remote financial vehicle locking, which comprises the following steps: 1, when a financial vehicle is remotely locked and started,a vehicle ECU (Electronic Control Unit) judges whether a temporary unlocking triggering condition is met or not, if so, a step 2 is executed, and if not, a vehicle locking state is kept; 2, a temporary unlocking function is triggered, and a network confirmation request is sent to the vehicle-mounted terminal by the vehicle ECU; 3, the vehicle-mounted terminal self-checks the network state, if thenetwork is disconnected, the step 4 is executed, and if the network is normal, the vehicle locking state is kept; 4, the vehicle ECU judges whether the temporary unlocking allowable frequency is larger than 0 or not, if yes, the step 5 is executed, and if not, the vehicle locking state is kept; and 5, the financial vehicle is allowed to be temporarily unlocked, and the engine is started. According to the invention, the financial vehicle can be allowed to be unlocked temporarily in a network-free state, so that the financial vehicle can run to an area covered by a network, and remote management of the financial vehicle by a management platform is facilitated.

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 ...
