INFOID:0000000009460647
VQ35DE
Component part Description
Generator (IC regulator) The IC regulator controls the power generation voltage by the tar-
get power generation voltage based on the received PWM com-
mand signal.
When there is no PWM command signal, the generator performs
the normal power generation according to the characteristic of the
IC regulator.
ECM The battery current sensor detects the charging/discharging cur-
rent of the battery. The ECM judges the battery condition based on
this signal.
The ECM judges whether to request more output via the power
generation voltage variable control according to the battery condi-
tion.
When performing the power generation voltage variable control,
the ECM calculates the target power generation voltage according
to the battery condition and sends the calculated value as the pow-
er generation command value to the IPDM E/R.
IPDM E/R The IPDM E/R converts the received power generation command
value into a pulse width modulated (PWM) command signal and
sends it to the IC regulator.
Combination meter (c harge warning lamp) The IC regulator warning function activates to illuminate the
charge warning lamp if any of the following symptoms occur while
generator is operating:
·Excessive voltage is produced.
·No voltage is produced.
Battery current sensor The battery current sensor is located on the negative battery cable
terminal. The battery current sensor detects the charging/dis-
charging current of the battery and sends a voltage signal to the
ECM according to the current value detected.

POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
System DiagramINFOID:0000000009460653
System DescriptionINFOID:0000000009460654
Power generation variable voltage control system has been adopted. By varying the voltage to the generator,
engine load due to power generation of the generator is reduced and fuel consumption is decreased.
NOTE:
When any malfunction is detected in the power generat ion variable voltage control system, power generation
is performed according to the characteristic of the IC regulator in the generator.
