[3]  ELECTRICAL CONTROL SYSTEM

(1) Electrical Control

An electrical control of GST system is as follows.

1. Shift  the  GST  lever  and  shuttle  lever  to  desired

position.

2. The output voltage of selected gear shift position is

output to microcomputer of the main ECU by lever

sensor.

3. The  main  ECU  detects  the  gear  shift position  with

GST  lever  sensor  and  shuttle  switch,  and  excites

various solenoid valves in accordance with selected

position.

4. When the desired solenoid is excited, oil is sent to

the desired shift piston.

5. A  pressure  in  the  circuit  is  raised  because  the

movement of shift piston shuts the shift check pin.

When the pressure in the circuit reaches 0.49 MPa

(5  kgf/cm

2

,  71  psi),  the  pressure  switch  becomes

"ON"

.

6. By means of the pressure switch's 

"ON"

, the main

ECU detects the present condition (traveling speed,

engine  speed  and  oil  temperature)  from  various

sensors,  and  pressure  in  the  hydraulic  clutch  is

raised according to the respective condition.

NOTE

• By means of speed increasing, speed

decreasing, traveling speed, engine speed and
oil temperature, the indicated pressure period
from c to d is controlled at appropriate pressure
respectively.

7. A  pressurizing  to  hydraulic  clutch  has  been  done

until it reaches the system pressure, and pressure in

the clutch is kept at this state.

  • 1. Shift the GST lever and shuttle lever to desired position.
  • 2. The output voltage of selected gear shift position is output to microcomputer of the main ECU by lever sensor.
  • 3. The main ECU detects the gear shift position with GST lever sensor and shuttle switch, and excites various solenoid valves in accordance with selected position.
  • 4. When the desired solenoid is excited, oil is sent to the desired shift piston.
  • 5. A pressure in the circuit is raised because the movement of shift piston shuts the shift check pin.
  • 6. By means of the pressure switch's "ON" , the main ECU detects the present condition (traveling speed, engine speed and oil temperature) from various sensors, and pressure in the hydraulic clutch is raised according to the respective condition.
  • 7. A pressurizing to hydraulic clutch has been done until it reaches the system pressure, and pressure in the clutch is kept at this state.
  • By means of speed increasing, speed decreasing, traveling speed, engine speed and oil temperature, the indicated pressure period from c to d is controlled at appropriate pressure respectively.
