Infiniti Drive Mode Selector

SYSTEM

Infiniti Drive Mode Selector : System Description


SYSTEM DIAGRAM






- The A/C auto amp. receives an operational state of the drive mode select switch and transmits a mode signal (See below.) to each unit via CAN communications.
- STANDARD: ON/OFF
- SPORT: ON/OFF
- ECO: ON/OFF
- SNOW: ON/OFF
- TCM transmits a mode state to ECM and ADAS control unit via CAN communications, based on a mode signal received from the A/C auto amp.
- ECM transmits an ECO pedal control signal to the ADAS control unit via CAN communications.
- The ADAS control unit controls pedal reaction force of the accelerator pedal actuator via ITS communications, based on an ECO pedal control signal received from ECM.
- The ADAS control unit receives a mode signal from the A/C auto amp. and changes the characteristics of the active trace control function via CAN communications with the ABS actuator and electric unit.

CONTROL DESCRIPTION

- The INFINITI drive mode selector switches a vehicle mode with the flick of a switch (Drive mode select switch) mounted on upper part of the center console and changes the control characteristics of the powertrain and chassis.
- The vehicle characteristics are controlled from the STANDARD mode ("" position of the drive mode select switch) to any mode listed below:
- SPORT: Changing the control characteristics of the transmission and active trace control function enables the use of high engine performance regions to obtain a light and crisp feel of the steering wheel.
- ECO: Fuel economy is enhanced by changing the control characteristics of the engine transmission and using an ECO pedal.
- SNOW: Changing the engine characteristics enables the obtainment of higher driving performance on roads with low coefficient of friction.

ENGINE TRANSMISSION CONTROL

- For further information on engine control, refer to "Infiniti Drive Mode Selector : System Description" Infiniti Drive Mode Selector.
"Infiniti Drive Mode Selector : System
Description".
ECO DRIVE INDICATOR
- This system supports ECO driving by controlling the ECO drive indicator lamp in the combination meter, according to an accelerator pedal depression during ECO mode.
- The ECO drive indicator lamp changes depending on the state of the fuel-efficient region, fuel-efficient limit region, or fuel-efficient region excess.






ACTIVE TRACE CONTROL FUNCTION

- SPORT mode is introduced.
- In SPORT mode, the changing of brake control characteristics allows the driver to control the vehicle motion more than in STANDARD mode.

ECO PEDAL CONTROL

- This system supports ECO driving by applying a load to the accelerator pedal according to an accelerator pedal operation during ECO mode.
- Reaction force to the accelerator pedal can be switched in two settings between STANDARD and SOFT.
Pedal reaction force to the accelerator pedal can be set to OFF, as necessary. (Switch the settings on the
NAVI screen.)
- ECO pedal control and ECO drive indicator lamp are interlocked each other to support ECO driving.
- For further information on ECO pedal control, refer to "Infiniti Drive Mode Selector : System Description" Infiniti Drive Mode Selector.

COMBINATION METER CONTROL

A mode state of the INFINITI drive mode selector is displayed on the information display built in the meter.
