Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 shows a main flow diagram of an embodiment of a remote upgrade security method provided by the present invention. In this embodiment, the method is applied to a vehicle Tbox device, and includes the following steps:
step S11, after receiving the upgrade request from OTA server, responding to user operation to trigger the upgrade flow; specifically, the OTA server will issue the upgrade package and the upgrade request to the vehicle Tbox device of each vehicle when the ECU software is updated. After receiving the upgrading request, the vehicle-mounted Tbox equipment displays the upgrading request on a human-computer interaction operation interface of the vehicle, and if a user clicks upgrading on the human-computer interaction operation interface, the clicking action of the user is converted into an upgrading starting instruction and is transmitted to the Tbox, so that the upgrading starting process is triggered;
step S12, when the current vehicle is checked to meet the upgrade condition, forbidding a vehicle one-key starting system and forbidding the application message communication functions of all CAN buses of the vehicle;
in this step, it is required to check whether the current vehicle meets the upgrade condition, specifically including checking at least one of an ACC gear, a vehicle locking and fortifying state, a vehicle speed, a battery power, a battery voltage, a handbrake state, a vehicle ignition state, a high-voltage charging state, a whole vehicle high-voltage state, a vehicle gear and a main driving safety belt state. It is understood that the upgrade check condition may be dynamically configured among the above conditions according to specific situations, and in particular, may be flexibly configured according to different upgraded ECU objects.
For example, in one specific example, the upgrade condition check may be performed according to table 1 below:
table 1: vehicle upgrade condition checking
If the vehicle meets the upgrade execution condition, starting the upgrade process, and if the vehicle does not meet the upgrade execution condition, quitting the upgrade;
after the function of a vehicle one-touch START system (PEPS) is forbidden, the vehicle cannot be switched ON/OFF by a START button and cannot be ignited to START the vehicle, so that the vehicle can be upgraded under a proper use scene (a scene of an unmanned vehicle); specifically, in one example, the PEPS functionality may be disabled by: firstly, the PEPS is controlled to enter an extended mode through a diagnosis service (such as 1003 instruction); then, the PEPS is controlled to enter the boot mode through a diagnosis service (such as a 1002 instruction); finally, the PEPS is controlled to be maintained in the boot mode by the diagnostic service (such as a 3E 80 instruction);
the CAN bus of all paths is forbidden to apply the message communication function, so that the bus load CAN be ensured to be at a lower level in the updating and refreshing process, the possible bus message interference is eliminated, and the success rate of updating and updating is ensured; specifically, in one example, all CAN application messaging may be disabled by: firstly, all ECUs are controlled to enter an expansion mode through a diagnosis service (such as 1003 instruction); secondly, controlling all CAN buses to forbid application message communication through a diagnosis service (such as 280301 instruction); finally, all CAN buses are maintained with disabled application messaging by the diagnostic service (e.g., 3E 80 instructions).
Step S13, according to the upgrade package from OTA server, carrying out upgrade operation to ECU software of the vehicle;
step S14, determining whether the current upgrade is successful, feeding back the upgrade result to the man-machine interaction interface of the vehicle, and reporting to the OTA server;
in a specific example, the step S14 further includes:
step S140, feeding back the upgrade result (success or failure) to a human-computer interaction interface of the vehicle;
step S141, after determining that the current upgrade fails, controlling to continue the upgrade operation of ECU software of the vehicle for at least one time;
step S142, after the upgrade finally fails, controlling the vehicle ECU software to automatically roll back and restore to the version before upgrade; it can be understood that, in an actual example, if the software rollback is successful, the upgrade is reported to be failed, but the software rollback is successful, so that the normal use of the vehicle is not influenced; if the software rollback still fails, the upgrading fails, the functions of the vehicle and the ECU fail, and the functions need to be solved after the user returns the vehicle;
and step S143, reporting the final result (success or failure) of the upgrade to the OTA server, and actively contacting the vehicle owner to perform corresponding processing when the background operator at the OTA server monitors the event.
It is understood that if the result of the upgrade is successful, the intermediate steps S141 and S142 may be omitted.
And step S15, after the upgrading is successful, recovering the use environment of the vehicle, and recovering the application message communication functions of the vehicle one-touch starting system and the CAN bus.
As shown in fig. 2, which is a schematic structural diagram illustrating an embodiment of a remote upgrade security system provided by the present invention, and shown in fig. 3 to fig. 4, in this embodiment, the remote upgrade security system 1 is applied to a vehicle-mounted Tbox device, and includes:
the upgrading triggering unit 11 is used for responding to user operation to trigger an upgrading process after receiving an upgrading request from the OTA server;
the upgrade preparation unit 12 is configured to disable a vehicle one-touch start system and disable application message communication functions of all CAN buses of a vehicle when it is detected that a current vehicle meets an upgrade condition;
the upgrading processing unit 13 is used for upgrading the ECU software of the vehicle according to the upgrading packet from the OTA server;

and the driving function recovery unit 15 is configured to recover the service environment of the vehicle and recover the application message communication functions of the vehicle one-touch start system and the CAN bus after the upgrade is successful.
More specifically, in one example, the upgrade provisioning unit 12 further includes:
the upgrade condition checking unit 120 is configured to check whether the current vehicle meets an upgrade condition, specifically including checking at least one of an ACC gear, a vehicle locking defense state, a vehicle speed, a battery level, a battery voltage, a handbrake state, a vehicle ignition state, a high-voltage charging state, a vehicle high-voltage state, a vehicle gear, and a main driving safety belt state;
an upgrade ending unit 121, configured to end the upgrade process when the upgrade condition checking unit checks that the current vehicle does not meet the upgrade condition;
a one-touch-enabled disabling unit 122 for disabling the vehicle one-touch-enabled system by: controlling a vehicle one-touch starting system to enter an extension mode; controlling a vehicle one-touch starting system to enter a boot mode; controlling the vehicle one-touch starting system to maintain in a boot mode;
a CAN application message communication disabling unit 123, configured to disable application message communication functions of all CAN buses of the vehicle by: controlling all ECUs to enter an expansion mode; controlling all CAN buses to forbid application message communication; and maintaining all CAN buses to keep forbidding application message communication.
More specifically, in an example, the upgrade result feedback unit 14 further includes:
the interface display unit 140 is used for feeding back the upgrade result to a human-computer interaction interface of the vehicle;
the repeated upgrading processing unit 141 is used for controlling the upgrading processing unit to continue upgrading the ECU software of the vehicle at least once after determining that the current upgrading fails;
