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
