C: CONTROL AND OPERATION
When actual vehicle speed is higher than the "set" speed, the motor in the actuator operates to move the throt-
Constant speed tle valve in the closing direction by the amount corresponding to the difference between the two speeds. When
control actual driving speed is lower than "set" speed, the motor operates to move the throttle valve in the opening
enabling direction according to the difference in speed.
When SET/COAST switch is pressed with main switch ON while the vehicle is being driven at a speed greater
Speed setting than 40 km/h (25 MPH), current flows to the actuator. This causes the clutch in the actuator to engage, enabling
control the motor to operate. The motor moves the throttle valve to the position corresponding to the accelerator pedal
position. The vehicle is driven at the set speed.
When SET/COAST switch is turned ON while the vehicle is cruising at a constant speed, the motor in the ac-
Deceleration tuator rotates to move the throttle valve in the closing direction. This causes the vehicle to decelerate by a cer-
control tain amount. When the switch is turned OFF, the vehicle speed is stored in memory and the vehicle maintains
that speed thereafter.
When RESUME/ACCEL switch is turned ON while the vehicle is cruising at a constant speed, the motor in the
Acceleration actuator rotates to move the throttle valve in the opening direction. This causes the vehicle to accelerate by a
control certain amount. When the switch is turned OFF, the vehicle speed is stored in memory and the vehicle main-
tains that speed thereafter.
When RESUME/ACCEL switch is turned ON after the cruise control is temporarily cancelled, vehicle speed
returns to that speed which was stored in memory just before the cruise control is cancelled. This occurs only
when the vehicle is running at a speed greater than 32 km/h (20 MPH).
Resume control In the following cases, however, the set vehicle speed is completely cleared. Therefore, no resume control is
performed.
(1) Ignition switch is turned OFF
(2) Main switch is turned OFF
When any of the following signals is entered into the clutch control module, the clutch is disengaged and the
cruise control is deactivated.
Manual cancel (1) Stop light switch ON signal (Brake pedal depressed) (2) Brake switch OFF signal (Brake pedal depressed)
control (3) Clutch switch OFF signal (Clutch pedal depressed – MT) (4) Inhibitor switch ON signal (Selector lever set
to "N" – AT) (5) CANCEL switch ON signal (Command switch cruise control lever pulled) (6) Ignition switch OFF
signal (7) Main switch OFF signal
Low speed limit When the vehicle speed drops below 32 km/h (20 MPH), the cruise control is automatically cancelled. Cruise
control control at any speed lower than 40 km/h (25 MPH) cannot be effected.
When the vehicle speed becomes 10 km/h (6 MPH) or more higher than the memorized speed while vehicle
is running utilizing the cruise control (in a downgrade, for example), the actuator's clutch is turned OFF so that
Motor control
the vehicle decelerates. When the vehicle's speed decreases by 8 km/h (5.0 MPH) or more from the memorized
speed, the clutch is turned ON again so that the cruise control resumes.
