Chapter One Control Principle of Some Systems
I. Control Principle of Starting System
1. Starting System
When the ignition switch is turned to ST position, the pull-in winding of the starter powers on, and
then the starting gear of stater motor is pushed to and engaged with the gear of flywheel. At the
same time, when the gears engage, the contact on the pull-in winding works and connects the
power supply from the battery to the starter motor so as to turn the motor and start up the engine.
When the ignition key returns back to the IG position, the holding coil of the starter powers off,
and under the action of spring force of the gear the motor disengages from the flywheel and the
flywheel of starter motor disconnects at the same time. The starting signal is transmitted to BCM
at the same time. The BCM utilizes the starting signal to determine that the system is in the
starting condition. In this case, the BCM will stop the action of motor of window glass regulator
so as to ensure that there is electric engergy enough to be supplied to starter motor.
2. Charging System
When the ignition switch is in IG position, the power supply from the ignition switch F17 is used
to excite the generator so as to ensure that it can generate electric power during the generator is
