Shift Control
The clutch pressure control solenoid is controlled by the signals from the switches and sensors. Thus, the clutch pressure is adjusted to be appropriate to the engine load state and vehicle driving state. It becomes possible to finely control the clutch hydraulic pressure with high precision and a smoother shift change characteristic is attained.
Shift Change
The clutch is controlled with the optimum timing and oil pressure by the engine speed, engine torque information, etc.
*1: Full phase real-time feedback control monitors movement of gear ratio at gear change, and controls oil pressure in real-time to achieve the best gear ratio.
Blipping Control
This system makes transmission clutch engage readily by controlling (synchronizing) engine revolution according to the (calculation of) engine revolution after shifting down.
- "BLIPPING CONTROL" functions.
- When downshifting by accelerator pedal depression at "D" position.
- When downshifting under the manual mode.
- TCM selects "BLIPPING CONTROL" or "NORMAL SHIFT CONTROL" according to the gear position, the selector lever position, the engine torque and the speed when accelerating by pedal depression.
- Revolution control demand signal is transmitted from TCM to ECM under "BLIPPING CONTROL".
- TCM synchronizes engine revolution according to the revolution control demand signal.
Tow Mode
- High driving torque is required for towing a heavy load. The tow mode enables torque-oriented driving by changing the shift schedule to that of delaying A/T gear shift timing (compared to normal driving).
- During downhill driving, the transmission assists deceleration by changing gear in cooperation with brake operation, according to driving conditions.
- TCM receives tow mode switch signal from combination meter via CAN communication.
