| Transmission hydraulic control |
Shifting control |
Shift pattern selection |
Based on the shift pattern selected by input from switches in each range, upshift and downshift points are set according to accelerator pedal opening angle and vehicle speed. |
| Linear solenoid control for each shift clutch |
Directly controls the linear solenoid for each shift clutch according to target gear range. The control values are constantly corrected by learning control and real-time feedback, contributing shifting quality improvement and prevention of quality aging. |
| Engine brake control |
In manual mode, controls high&low reverse clutch solenoid so that engine brake is applied at 1st speed. |
| Lock-up control |
Basic lock-up control |
Based on the shift pattern selected by input from switches in each range, lock-up engagement and release points are set according to accelerator pedal opening angle and vehicle speed. In accordance with these points, the lock-up solenoid is controlled to engage and release the lock-up clutch in torque converter. |
| Smooth control |
In lock-up clutch engagement, gradually changes pressure to provide smooth engagement. |
| Line pressure control |
Controls the line pressure in accordance with the input torque, front vehicle speed signal, rear vehicle speed signal and gear range. |
| AWD center differential control |
Normal transfer control |
Torque sensitive control |
Adjusts the multi-plate clutch (LSD) pressure according to torque input to the transfer. |
| Control for turning |
Adjusts the LSD pressure based on the steering angle and vehicle speed. |
| Slip control |
LSD pressure increases if front or rear wheels start to slip. |
| Cooperation control |
Control during ABS operation |
LSD pressure is adjusted to the set value during ABS operation. |
| Control during braking |
LSD pressure is adjusted to the set value while the brake switch is ON with the throttle valve fully closed. |
| Control during VDC and TCS operation |
LSD pressure is adjusted to the set value during VDC and TCS operation. |
