System Diagram
WARNING: This page is about a different car, the 2012 Infiniti M35h. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- This information provides description only about the control by HPCM. For overall control, refer to "INFINITI DRIVE MODE SELECTOR ".
- ECO pedal control is only for vehicles with intelligent pedal (distance control assist).
Infiniti Drive Mode Selector
- A/C auto amp. receives an operation state signal of the drive mode select switch and transmits a mode signal (see below) to TCM via CAN communication.
- STANDARD: ON/OFF
- SPORT: ON/OFF
- ECO: ON/OFF
- SNOW: ON/OFF
- TCM transmits a mode state signal to HPCM via CAN communication, based on a ECO mode signal received from A/C auto amp.
- HPCM controls torque appropriate to each mode, based on a ECO mode signal received from TCM via CAN communication.
- ECM controls the throttle position characteristics and controls engine output torque, based on the command signal from HPCM.
- Traction motor inverter controls the traction motor output torque, based on a command signal from HPCM.
- When ECO mode is engaged, the ECO mode indicator lamp is turned ON or blinks based on the ECO mode indicator lamp signal received by CAN communication from HPCM.
ECO Pedal Control
- AV control unit transmits the ECO pedal reaction force setting signal (Standard/Soft/OFF) to HPCM via CAN communication.
NOTE:
The ECO pedal reaction force setting signal which determines reaction force of the accelerator pedal can be selected on the settings screen of the Multi AV System.
- HPCM transmits the ECO pedal reaction force control signal to ADAS control unit via CAN communication, based on a ECO mode signal received from TCM via CAN communication and an ECO pedal reaction force setting signal received from AV control unit via CAN communication.
- HPCM sends back an ECO pedal reaction force setting signal received from the AV control unit to the AV control unit for confirmation.
- ADAS control unit controls pedal reaction force of the accelerator pedal actuator via ITS communication, based on a ECO pedal reaction force control signal received from HPCM.
