In other modules (such as main control module 400).
S2: current VIN is obtained.After OBD interface is connect with vehicle-mounted OBD interface, so that it may obtain current VIN.
S3: the control OBU failure when current VIN and original VIN are inconsistent.
In one embodiment of invention, OBU relevant information includes at least the state letter whether being disassembled for indicating OBU
Breath, then step S3 includes:
When current VIN and original VIN are inconsistent, the status information is illegal disassembly status information, by illegally tearing open
It unloads status information and assert that the OBU is illegally dismantled.
Specifically, in the ESAM of OBU (the specific chip that ESAM is security module) system file, some preset word
The different working condition of the representative OBU of section.Wherein, indicate that OBU is illegally dismantled when the numerical value of the byte position becomes 0.OBU goes out
It is 0 that the byte position is defaulted when factory, and when OBU is powered on and is activated for the first time, which becomes 1, is indicated when wherein byte position is 1
OBU is in normal working condition.After OBD interface is connect with vehicle-mounted OBD interface, so that it may obtain current VIN.Main control module will
The original VIN prestored in current VIN and security module is compared, if currently VIN and original VIN is inconsistent, assert OBU
It is illegally dismantled, which is become 0, wherein indicated that OBU is illegally dismantled when the byte position becomes 0, control OBU at this time
Failure.When the vehicle of the label with illegal disassembly status information drives into expressway entrance and exit lane, handed over RSU
Mutually, and to it corresponding processing is done.
In one embodiment of the invention, OBU further includes capacitor, wherein capacitor at least with communication module, security module
It is connected with one of main control module.It charges when for being connected to vehicle power supply, and when not being connected to vehicle power supply to logical
Letter module, security module and main control module discharge, control method further include: when capacitor is connected to vehicle power supply to capacitor into
Row charging；It discharges when capacitor is not connected to vehicle power supply communication module, security module and main control module.
Specifically, capacitor charges when connecting power supply, and when being not connected to power supply to communication module, security module and
Main control module discharges, and can be prevented by capacitor because OBU electrification reset caused by shaking causes to produce disassembly status
Raw erroneous judgement.
The invention also discloses a kind of computer readable storage medium, which has program,
Program for realizing above-described embodiment control method.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
