Specifically, the qualified range corresponding to the test parameter can be set by the user, the test item is determined to be qualified when the test parameter is within the qualified range, and the test item is determined to be unqualified when the test parameter is outside the qualified range.
In some embodiments, as shown in fig. 3 and 4, testing latch assembly 4 further includes testing the signal transmission quality of the CAN high communication line, the CAN low communication line, and the LIN signal line; testing the impedance of a connector of the locking assembly 4, testing a power supply 32 of the locking assembly 4 and testing the analog quantity acquisition precision of the locking assembly 4; testing switching parameters of the locking assembly 4 during switching between the P gear and the non-P gear; the switching parameters include a switching time of the lock assembly 4 when the shift position is switched and shift position information of the lock assembly 4 after the end of the switching.
It CAN be understood that the signal transmission quality when the locking assembly 4 is connected with the CAN high-pass communication line, the CAN low-pass communication line and the LIN signal line CAN be determined by testing the differential voltage and the signal rising and falling time of the two CAN high-pass and CAN low-pass communication lines in the explicit message and the implicit message, the explicit level value and the implicit level value of the LIN signal line and the signal rising and falling time during communication and other related data. The performance of the connector of latch assembly 4 can be better tested by testing the impedance between the various pins of the connector of latch assembly 4 and power supply 32, ground. The test of the power supply 32 can be well realized by collecting a voltage signal output by the power supply 32, a system working current, a system sleep current, a power-up and power-down logic test, a sleep awakening logic test and the like, so that the power supply 32 can safely and reliably provide power for the operation of the whole function test system, and the test reliability of the locking comprehensive test is improved. The acquisition precision of the analog quantity of the locking assembly 4 can be tested by monitoring temperature acquisition and voltage acquisition, so that the accuracy and reliability of the signal output by the locking assembly 4 are ensured. When the lock assembly 4 is used for gear shifting, the time required by the lock assembly 4 in the gear shifting process and the position of the lock assembly 4 after the gear shifting are finished can better express the gear shifting performance of the lock assembly 4, so the gear shifting performance of the lock assembly 4 can be judged according to the shifting time and the gear position information. Specifically, when it is necessary to perform the performance of switching the lock assembly 4 to the P range, the processing device 3 controls the motor inside the lock assembly 4 to rotate in the forward direction, drives the transmission shaft inside the lock assembly 4 to the P range position, and detects signals of the position sensors during operation and after the motor is stopped, and the time taken until the motor is stopped before the motor is operated. The operation when the performance of switching the lockup assembly 4 to the non-P range needs to be performed need not be described in detail.
