Step S2045, if the current detection duration is less than the preset duration, increasing the second data amount of the pressure data, and returning to the step of inputting the pressure data into the data processing module of the vehicle to be tested through the bus of the vehicle to be tested.
In an alternative embodiment, when the first data amount is the same as the second data amount, but the test duration does not meet the preset duration, so that the pressure data amount borne by the bus can be further increased to test, so that the second data amount is increased, the transmission of the pressure data through the bus is continuously performed to obtain the first data amount, and the comparison of the first data amount and the second data amount is performed to judge whether the frame loss condition occurs in the bus.

And step S304, comparing the second pressure data information with the first pressure data information to obtain a vehicle-to-machine test result.
Specifically, the step S304 includes:
step S3041, determining the transmission time of each frame of data according to the reception time and the transmission time.
In an alternative embodiment, the bus data transmission efficiency is also detected in addition to the bearing capacity of the bus, and therefore, the present embodiment detects the transmission time of each frame of pressure data and the reception time to the data processing module to confirm the transmission time of this frame of pressure data in the bus.
