Mazda CX-5 Service & Repair Manual: Engine Transaxle Integration Control [Fw6 A EL, Fw6 Ax EL]
Outline
-
The TCM controls engine output torque and reduces transaxle output shaft torque fluctuation during auto shifting, and reduces shock occurring from the vehicle during shifting.
Construction
Operation
-
During auto shifting, the TCM sends the torque reduction request signal using the CAN system and temporarily reduces the engine output torque by the engine ignition timing retard control. As a result, transaxle output shaft torque fluctuation is reduced during auto shifting by smooth engagement of the clutch.
-
In addition, the TCM receives the engine output torque from the PCM via the CAN signal to determine the clutch engagement pressure according to the engine output torque. As a result, the clutch hydraulic control setting accuracy is increased and smooth shift performance is achieved.
