Abstract

The invention belongs to the technical field of transmission detection and relates to an AMT (Automated Manual Transmission) offline detection platform and a control method thereof. The AMT offline detection platform includes a computer, a test tool, a control unit, a base, a driving motor which is mounted on the base, and a transmission bracket mounted on the base; the output shaft of the drivingmotor is connected with a coupling used for connecting the output shaft of a transmission to be detected; the control unit is connected with the test tool through a wire harness; the test tool is connected with the computer through a data line; the control unit receives an offline detection request from an operator, and controls each pneumatic actuator to complete offline detection; a rotationalspeed sensor and a position sensor feed back rotational speed signals and position signals which are monitored in real time to the control unit; the control unit transmits relevant status signals andthe like to the computer, so that the computer can display and record the signals in real time; and therefore, the operator can be facilitated to check and judge whether a gear request is completed, whether the gear shift of the transmission is in place, and whether a countershaft brake reaches a braking effect.

Description

technical field [0001] The invention relates to the technical field of transmission detection, in particular to an AMT transmission off-line detection platform and a control method thereof. Background technique [0002] The AMT transmission is different from the traditional mechanical transmission. The operator cannot directly select and shift the transmission through the selection lever for testing when it is off-line. The gear selection and shifting actuator of AMT is a pneumatic actuator, which must be controlled by the control unit to complete the gear selection and shifting action. The current off-line testing platform for transmissions is only suitable for off-line testing of traditional mechanical transmissions, and there is currently a lack of a testing platform suitable for AMT transmissions. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention proposes an automatic transmission off-line detection platform and a control me...
