Specifically, the present embodiment completes factory reset of the IVI system of one vehicle to be processed, and the adopted devices include the vehicle to be processed, a diagnostic device, a message monitoring device, and a one-to-two patch cord. During specific implementation, a vehicle to be processed stays at a detection station of a production line, a one-to-two patch cord is connected to an OBD diagnosis port of the vehicle to be processed, one of two plug connectors is connected with diagnosis equipment, and the other plug connector is connected with message monitoring equipment. The diagnosis equipment needs to develop a process of writing input and output control functions for the IVI system according to routine control, and mainly comprises the following two steps: firstly, a routine control command is transmitted to the IVI for searching factory default values; and secondly, the diagnostic equipment sends a reset diagnostic service instruction to reset the IVI system. After the program is developed, the diagnosis equipment can support the IVI system of the real vehicle to restore the factory settings.
Further, as shown in fig. 2, the step S101 specifically includes:
and S1011, acquiring protocol channel information of the diagnostic equipment, and controlling the protocol channel information of the built-in IVI system of the vehicle to be processed to be consistent with the protocol channel information of the diagnostic equipment, so that the IVI system and the diagnostic equipment are in a data interaction state.
And S1012, triggering and operating the diagnostic equipment to start diagnostic service, acquiring an extended mode switching instruction sent by the diagnostic equipment, and controlling the IVI system and the diagnostic equipment to enter an extended session mode so as to enable the IVI system to be in a detection mode.
Specifically, when the IVI system and the diagnostic device are in a data interaction state, the diagnostic device sends an extended mode switching instruction to the IVI system, and the diagnostic device and the IVI system enter an extended session mode. The extended mode switching instruction is a 1003 instruction.
S102, triggering a safety access program for operating the diagnosis equipment, acquiring a safety access instruction, and judging whether the safety access instruction is legal or not.
Specifically, after the IVI system is switched to the extended session mode, the diagnosis device sends an IVI system security access instruction again, the diagnosis device sends a seed request message to the IVI system, the IVI system randomly generates an IVI system seed after receiving the message and feeds the IVI system seed back to the diagnosis device, and the diagnosis device calculates a diagnosis key after receiving the IVI system seed; after receiving the diagnosis secret key, the IVI system compares the diagnosis secret key with the secret key of the IVI system to judge whether the security access instruction is legal or not.
Further, as shown in fig. 3, the step S102 specifically includes:
s1021, when the IVI system is in a detection mode, acquiring a request seed message sent by the diagnosis equipment, and randomly generating an IVI system seed;
specifically, the diagnosis device sends 2701 instruction request seed message to the IVI system, and the message monitoring device can monitor the operation condition and determine whether it is responded.
S1022, feeding back the IVI system seed to the diagnostic equipment, and judging whether the diagnostic equipment successfully receives the IVI system seed.
And S1023, if so, controlling the diagnosis equipment to calculate a diagnosis key corresponding to the IVI system seed.
S1024, obtaining the diagnosis secret key, and comparing the diagnosis secret key with a secret key of the IVI system to judge whether the security access instruction is legal or not;
specifically, the diagnostic device sends 2702 instruction to the IVI system to send the diagnostic key to the IVI system, and the message monitoring device can monitor the operation status and confirm whether it is responding positively.
S103, if yes, triggering and operating an input/output control program of the diagnostic equipment, acquiring a routine control instruction, enabling the IVI system to shield an actual input/output signal value, and setting the actual input/output signal value according to a preset factory default value;
s104, when the IVI system is confirmed to be written into a factory default value, triggering a reset program for running the diagnostic equipment, and obtaining a reset instruction so that the diagnostic equipment exits the diagnostic service;
specifically, the message is monitored by the message monitoring device, and after the fact that the IVI system has written the factory default value is confirmed, the diagnosis device sends a reset instruction to the IVI system, wherein the reset instruction is 1101 instruction. After the IVI system is reset, an IVI system interface is checked through a 1101 instruction, and functions on a touch screen of the IVI system all display a factory state.
In summary, the following steps: when the IVI system and the diagnostic equipment are in a data interaction state, the diagnostic equipment can be triggered at a corresponding node, so that the IVI system obtains an extended mode switching instruction and a safe access instruction and writes a factory default value into the IVI system, and after the extended mode switching instruction and the safe access instruction are successful, the diagnostic equipment continues to send a reset instruction to the IVI system, and all functions of the IVI system are restored to a factory set state; the IVI system is automatically subjected to diagnosis routine control by additionally arranging routine control on a detection station before the vehicle to be processed enters a warehouse, so that the IVI system can automatically write factory default values, and the IVI system can restore factory settings.
