Example Embodiment

[0026] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.
[0027] figure 1 It is a flow chart of the activation method of the vehicle-mounted unit according to the embodiment of the present invention. like figure 1 As shown, the method may include the following processing steps:
[0028] Step S102: obtaining the preset mode information of the OBU;
[0029] Step S104: Activate the OBU after the successful transaction between the OBU and the RSU according to the acquired preset mode information.
[0030] In the related art, the way of activating the OBU not only increases the hardware cost of the OBU system, but also increases the operational complexity. using as figure 1 In the method shown, the preprocessing mode of the OBU is preset, and after the preset mode information of the OBU is obtained, the OBU can be activated after the successful transaction between the OBU and the RSU according to the obtained preset mode information, which can not only avoid adding additional settings in the OBU system. The hardware activation device also avoids artificially triggering the OBU for activation, and solves the problem that the method of activating the OBU in the related art not only increases the hardware cost of the OBU system, but also increases the operational complexity, and thus does not need to modify the hardware structure of the OBU system. , In the case of adding a hardware activation device or peripheral auxiliary activation hardware, the independent activation of the OBU is completed, and the remote activation of the OBU is realized.
[0031] Preferably, in step S104, activating the OBU after the successful transaction between the OBU and the RSU according to the acquired preset mode information may include the following steps:
[0032] Step S1: setting the status flag information of the OBU according to the obtained preset mode information;
[0033] Step S2: determine whether the transaction between OBU and RSU is successful;
[0034] Step S3: If the transaction is successful, activate the OBU according to the set status flag information.
[0035] In a preferred embodiment, the issuing operation of the OBU can be completed at the operator's service network, and the tamper-proof flag of the system information in the OBU's security access module is set to the pre-activation mode; then the OBU is installed on the user's vehicle; finally , when the vehicle successfully completes the transaction through the ETC lane, the OBU judges whether it is currently in the pre-activated state. If it is in the pre-activated state, the OBU automatically updates the tamper-evident flag information of the system information in its security access module to the activated state. Self-activation also enables tamper; if not pre-activated, do nothing.
[0036] Preferably, in the above step S1, setting the status flag information of the OBU according to the acquired preset mode information may include the following operations:
[0037] Step S11: determine whether the preset mode information of the tamper-proof status bit of the security access module in the OBU is a pre-activation mode;
[0038] Step S12: If yes, set the status flag information of the OBU as a pre-activated state.
[0039] Preferably, in step S12, after setting the state flag information of the OBU to the pre-activated state, the following processing may also be included:
[0040] Step S13 : setting the state information of the tamper-evident information flag bit of the vehicle service table VST to an active state.
[0041] In the preferred embodiment, figure 2 This is the process flow chart of the pre-activation mode during the OBU reset process according to the preferred embodiment of the present invention. like figure 2As shown, the processing flow may include the following steps:
[0042] Step S202: OBU system reset;
[0043] Step S204: obtaining the preset mode information of the tamper-proof status bit in the OBU security information module;
[0044] Step S206: determine whether the preset mode information is a pre-activation mode; if yes, continue to step S208; if not, go to step S212;
[0045] Step S208: setting the state flag information of the OBU to be a pre-activated state;
[0046] Step S210: setting the VST anti-dismantling information flag to an active state to ensure that the OBU in the pre-activated state can pass through the ETC lane normally; enter the OBU system dormancy; the process ends;
[0047] Step S212: determine whether the preset mode information is an active mode; if so, go to step S214; if not, go to step S216;
[0048] Step S214: set the VST anti-dismantling information flag to an active state; enter the OBU system dormancy; the process ends;
[0049] Step S216: Set the VST anti-disassembly information flag bit to the disassembly state; enter the OBU system dormancy; and the process ends.
[0050] In this preferred embodiment, if it is not in the pre-activation mode, the state of the VST anti-tamper information flag bit can be set according to the actual situation, so as to ensure the availability of the tamper-proof device. This process ensures that the OBU in the pre-activation mode can complete normal transactions with the ETC lane equipment.
[0051] In a preferred implementation process, in the above step S3, activating the OBU according to the set state flag information may include the following steps:
[0052] Step S31: judging whether the set state flag information is a pre-activated state;
[0053] Step S32: If yes, activate the OBU and clear the status flag information.
[0054] Combine below image 3 and Figure 4 The above preferred implementation process is further described.
[0055] image 3 This is a flow chart of the OBU completing autonomous activation in the ETC transaction process according to the preferred embodiment of the present invention. like image 3 As shown, the process may include the following processing steps:
[0056] Step S302: the OBU system receives the air interface beacon service table (BST) data, and the OBU system enters a transaction state;
[0057] Step S304: completing the relevant flow of the ETC transaction;
[0058] Step S306: determine whether the ETC transaction is successful, if successful, continue to perform step S308; if not, enter the normal processing flow, and the OBU system sleeps;
[0059] Step S308: the OBU judges whether it is currently in a pre-activated state; if so, continue to perform step S310; if not, enter the normal processing flow, and the OBU system is dormant;
[0060] Step S310: The OBU performs an autonomous activation operation, and this process can ensure that the OBU completes the autonomous activation operation.
[0061] Step S312: The OBU clears the status flag information, and enters the normal processing flow, and the OBU system sleeps.
[0062] In this preferred embodiment, if it is not in the pre-activation state or the ETC transaction is unsuccessful, the autonomous activation operation is not performed, and the normal related processing flow is directly performed. The above process can not only ensure that the OBU can only activate itself after completing a normal ETC transaction, but also can judge whether the ETC transaction is actually completed, so as to avoid the OBU from performing other operations (for example: issuance operations) and the interference of air interface data. Mis-activation operation, thus ensuring the reliability of autonomous activation.
[0063] Figure 4 This is the processing flow chart of the OBU anti-dismantling interruption according to the preferred embodiment of the present invention. like Figure 4 As shown, the process may include the following processing steps:
[0064] Step S402: the OBU system enters the anti-dismantling interruption;
[0065] Step S404: obtaining the anti-dismantling flag bit information in the OBU security access module;
[0066] Step S406: determine whether the OBU is currently in the pre-activation mode; if not, go to step S408; if so, go to step S410;
[0067] Step S408: if it is not in the pre-activation mode, the number of tamper-proofing is deducted according to the tamper-proof flag position, and the process is exited after performing relevant processing. This process can ensure the reliable operation of the tamper-proof device;
[0068] Step S410: If it is in the pre-activation mode, the number of anti-dismantling is not deducted, and the status flag information of the OBU is set, and then exits after the relevant processing is performed.
[0069] In this preferred embodiment, the reliable operation of the tamper-proof device is ensured, and the tamper-proof device of the OBU can run stably in both the pre-activation and activation modes of the OBU.
