WIRING SYSTEM
Cruise Control
General Description
The circuit consists of cruise control unit, cruise main
switch, combination switch clutch switch (M/T), mode
switch (A/T), stoplight switch, actuator and indicator
lights. Cruise control system keeps the vehicle running at
a fix speed until a signal canceling this fixed speed is
received.When the cruise main switch is turned on with
the vehicle in the running mode, the battery voltage is
applied to the control unit.
When a signal from the combination switch is input to the
control unit while vehicle is in this state, the actuator is
activated to operate the system. Also, while the system is
operating, the cruise indicator light in the meter panel
lights up.
Set Function
When the cruise main switch turned on and the set switch
is depressed with the vehicle speed within the set limit
and cancel operation is refused the vehicle speed when
the set switch is released is stored in the control unit as
the set speed. But in case of the vehicle speed is over
maximum limit speed of cruise control, maximum limit
speed in the control unit is stored as the set speed.
Resume Function
Unless the vehicle speed falls below the minimum speed
limit after canceling the set speed by the cancel switch,
pushing the resume switch causes the vehicle to resume
the speed before cancellation.
Acceleration Function
During cruise control driving, pushing the acceleration
switch (on time is more than 0.6 sec.) causes an increase
in cruise speed and vehicle accelerates at a controlled
rate until acceleration switch released. Vehicle speed at
the acceleration switch released plus 1.0 km/h is stored in
the control unit as the set speed.
Top Up Function
During cruise control driving, the set speed can be
increased 1.6 km/h each time by operating the
accelerator switch quickly within 0.6 sec.
Coast Function
During cruise control driving, pushing the coast switch (on
time is more than 0.6 sec.) causes a decrease in cruise
speed and the vehicle decelerate at a controlled rate until
coast switch released. Vehicle speed at the coast switch
released ,minus 1.0 km/h is stored in the control unit as
the set speed.
Top down Function
During cruise control driving, the set speed can be
lowered 1.6 km/h each time by operating the coast switch
quickly within 0.6 sec.
Cancel Function
During cruise control driving, the cruise control is
released if the control unit receives a signal from the
cancel switch, mode switch, clutch switch or brake
switch. But the set speed is not erased.
Down Cancel Function
The cruise control is canceled when the vehicle speed
becomes the set speed minus 20 km/h during the cruise
control working and the set speed is erased.
Over Drive (OD) Cancel Function
OD cancel function is required when the vehicle speed
becomes the set speed minus 3 km/h during the cruise
control working. OD cancel function is enabled when the
acceleration function and/or resume function are working
except the vehicle speed is in more than 120 km/h.
