DRIVER ADAPTIVE SHIFT CONTROL OUTLINE [AW6A-EL, AW6AX-EL]

id051723102600

• The AW6A(X) -EL automatic transaxle does not have a driving mode selection switch that allows drivers to select a mode themselves. The vehicle is ordinarily in NORMAL mode. However, when specific conditions are met, the TCM selects a shifting pattern appropriate to driving conditions from all of the shifting patterns and switches automatically.

Mode

Description

NORMAL

•  Used during normal driving.

AAS

•  In this mode, shift point and TCC point settings are higher than in the normal driving condition for generating high engine speed and output.

MANUAL

(See MANUAL MODE SHIFT CONTROL OUTLINE [AW6A-EL, AW6AX-EL].)

HIGH TEMP

•  When ATF temperature becomes too high, this mode activates TCC at an earlier timing to stop the temperature rise and lower the temperature.

CRUISE CONTROL

•  When cruise control is ON, gears are fixed to perform smooth driving.

DOWN-SLOPE

•  When the vehicle is driven down a slope, the TCM detects the gradient based on the signal from the PCM and the engine speed, and switches the drive mode to DOWN-SLOPE mode. Due to this, load on the brakes is reduced.

UP-SLOPE

•  When driving up a slope, TCM detects an up-slope based on the engine control unit signal and output speed. TCM switches to UP-SLOPE mode to prevent driving force drop.

COLD

•  TCM detects that the engine is cold based on the signal (ECT signal) from the PCM when the ignition switch is on. TCM switches to cold mode to improve warm-up performance.

Mode	Description
NORMAL	• Used during normal driving.
AAS	• In this mode, shift point and TCC point settings are higher than in the normal driving condition for generating high engine speed and output.
MANUAL	(See MANUAL MODE SHIFT CONTROL OUTLINE [AW6A-EL, AW6AX-EL].)
HIGH TEMP	• When ATF temperature becomes too high, this mode activates TCC at an earlier timing to stop the temperature rise and lower the temperature.
CRUISE CONTROL	• When cruise control is ON, gears are fixed to perform smooth driving.
DOWN-SLOPE	• When the vehicle is driven down a slope, the TCM detects the gradient based on the signal from the PCM and the engine speed, and switches the drive mode to DOWN-SLOPE mode. Due to this, load on the brakes is reduced.
UP-SLOPE	• When driving up a slope, TCM detects an up-slope based on the engine control unit signal and output speed. TCM switches to UP-SLOPE mode to prevent driving force drop.
COLD	• TCM detects that the engine is cold based on the signal (ECT signal) from the PCM when the ignition switch is on. TCM switches to cold mode to improve warm-up performance.

Active Adaptive Shift (AAS) Mode

• When certain conditions are met, AAS mode is automatically selected from normal mode. In AAS mode, the shift point is set higher than the normal shift point so that high-engine speed, high-output conditions are available.

• AAS mode is canceled when the vehicle speed remains constant (stable vehicle behavior).

Conditions for switching to active adaptive shift (AAS) mode

• The accelerator pedal is depressed fully to accelerate rapidly while driving in D range.

• Rapid acceleration or deceleration continues for a certain period of time while driving in D range.

Shift control in active adaptive shift (AAS) mode

• Shift control is performed according to the shift pattern in AAS mode.

• When the driver releases the accelerator pedal fully and rapidly, the gear position is maintained at the position before accelerator pedal was released. Due to this, re-acceleration and vehicle control performance have been improved. If the accelerator pedal is released slowly, the gears shift up according to the shift pattern.

• While cornering the vehicle, the gear position is maintained at the position before the vehicle was cornered to facilitate re-acceleration after the corner. The gears do not shift up if the accelerator pedal is depressed fully while cornering the vehicle.

Forced cancellation of active adaptive shift (AAS) mode

• AAS mode is forcibly cancelled under the following conditions:

― The vehicle speed in the cruise control system is reset.

― The selector lever is shifted to M range while driving in D range.
