System Construction: Notes
WARNING: This page is about a different car, the 2006 Infiniti G35. However, it is still accessible from the selected car via links, so may be relevant.
A small network is constructed between the display and A/C auto amp., air mix door motor, mode door motor and intake door motor. The display and A/C auto amp. and motors are connected by data transmission lines and motor power supply lines. The LAN network is built through the ground circuits of each door motor.
Addresses, motor opening angle signals, motor stop signals and error checking messages are all transmitted through the data transmission lines connecting the display and A/C auto amp. and each door motor.
The following functions are contained in LCUs built into the air mix door motor, the mode door motor and the intake door motor.
- Address
- Motor opening angle signals
- Data transmission
- Motor stop and drive decision
- Opening angle sensor (PBR function)
- Comparison
- Decision (Display and A/C auto amp. indicated value and motor opening angle comparison)
