| Functions
of the EDFC : |
| |
| 1.
Damping force control function (16 levels
/ 32 levels) |
| The
damping-force-control-type shock absorbers
normally have a built in damping force control
function for 16 levels. This function controls
the damping force by adjusting the rate
of oil flow in the bypass through raising
and lowering the damping force control needle
built in piston rod for 16 levels. In the
EDFC, this function is performed by a stepping
motor installed on the top of piston rod,
realizing a 16-level control, the same as
in the manual control. Moreover, the operation
by the controller with a decreased rotation
angle has realized a finer adjustment of
a 32-level mode in the same control range.
The damping force for the front and rear
wheels can be separately controlled, and
the right and left wheels are simultaneously
controlled. |

| 2.
Damping force level maintaining function
|
| An
EDFC switch is connected with the key position
of the vehicle, the same as in general car
audio components. If the EDFC power switch
is continuously turned on, the EDFC can
store in memory the click position setting
when the driver gets out of the car and
the key switch is turned off. Thus, when
the engine is restarted, he/she can drive
using the same setting. All memory contents
are deleted when the EDFC power switch is
turned off. The electric current to maintain
memory is as slight as the current necessary
for a standard equipment clock, and there
is little possibility of a dead battery.

| 4.
Damping force level memory function |
| It
is equipped with a function to store in
memory three settings of the damping force.
The level setting in memory can be maintained
even if the engine is turned off. The memory
contents can be recalled with the touch
of a button. Moreover, the stored memory
contents can be easily changed by pushing
the button for more than two seconds. |
| |
| 5.
Damping force level resetting function |
| After
the EDFC is installed, the driver will put
it into a return-to-origin mode by rotating
the motor in the clockwise direction when
the power is turned on. With this operation,
the controller can recognize the origin
of the damping force control needle. The
EDFC is equipped with a function to execute
the return-to-origin mode compulsorily in
the following occasions: in the case of
installation or detachment of the EDFC,
or when the control level is changed from
16-level to 32-level, or when the level
displayed is different from the actual one
due to external and mechanical reasons.
This operation is not necessary in the normal
driving, however. Turning on the main power
again after turning it off can reset the
damping force level. At this time, the memory
contents are also reset. |
| |
| 6.
Self-checking/warning function |
| In
the case where the EDFC does not function
correctly (due to an overcurrent or detached
wires, etc.), all three memory buttons will
blink red with an alarm sound and an error
indication displayed, and the driver can
confirm the position of the malfunctioning
motor on the screen. |
| |
| 7.
Volume/brightness control function |
| The
beep sound volume while operating the EDFC
can be set at three levels and can also
be put into a silent mode. It is also possible
to adjust the brightness of the display
at three levels. This adjustment is connected
with the power source for lamps, and it
functions when the dimmer function is in
operation at night. |
| |
| 8.
Mis-operation preventative function |
|
The EDFC is equipped
with a lock mode, which prevents mis-operation.
The 'key' mark is displayed and all operations
become impossible including turning the
power on and off. It is useful when the
driver allows another driver to drive
an EDFC-equipped vehicle.
