System Diagram
WARNING: This page is about a different car, the 2013 Infiniti M37. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- This article provides descriptions only about the control by ECM.
For overall control, refer to "INFINITI DRIVE MODE SELECTOR: SYSTEM DESCRIPTION ".
- 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 ECM via CAN communication, based on a ECO mode signal received from the A/C auto amp.
- ECM controls throttle angle characteristics and torque appropriate to each mode, based on a ECO mode signal received from TCM via CAN communication.
- The combination meter turns ON or blinks (with ECO pedal) the ECO drive indicator when in ECO mode, based on a ECO drive indicator control signal received from ECM via CAN communication.
ECO pedal control
- The AV control unit transmits an ECO pedal reaction force setting signal (Standard/Soft/OFF) to ECM via CAN communication.
NOTE:
An 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.
- ECM transmits an ECO pedal reaction force control signal to the 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 the AV control unit via CAN communication.
- ECM sends back an ECO pedal reaction force setting signal received from the AV control unit to the AV control unit for confirmation.
- The ADAS control unit controls pedal reaction force of the accelerator pedal actuator via ITS communication, based on an ECO pedal reaction force control signal received from the ADAS control unit.
