Outline<\/p>\n

\u2022 The TCM implements auto shift control according to the vehicle speed and accelerator pedal depression amount while in D position.<\/div>\n
\u2022 When the vehicle is stopped with the selector lever is in the D position and the brake pedal depressed, the neutral idle control is performed which internally controls the automatic transaxle to be in the neutral condition while the selector lever is in the D position. When the brake pedal is being released, the clutch is engaged immediately and the automatic transaxle returns to the normal D position condition.<\/div>\n
\u2022 When SPORT mode is selected using the drive selection switch, a lower gear relative to normal mode is selected, and control is performed so that a higher operating force can be assured.<\/div>\n
\u2022 When implementing the automatic shift control, the TCM determines the driving conditions based on each input signal and selects the drive mode appropriate to the driving conditions. In addition, information such as torque and gear changes is exchanged via PCM and CAN communication and control is performed so as to achieve optimum drive force according to the driving scenario.<\/div>\n

Driving range determination<\/p>\n

\n
\n
\u2022 If a D position signal is input and an M position signal is not input, the TCM implements auto shift control.<\/div>\n<\/dd>\n<\/dl>\n

Driving mode determination<\/p>\n

\n
\n
\u2022 Normal mode and SPORT mode can be selected using the drive selection switch and the following modes are switched automatically based on the driving conditions in conjunction with normal mode\/SPORT mode.<\/div>\n
\n
\n
\u2015 AAS (Active Adaptive Shift) mode: Automatically controls the optimum shift point according to the road conditions and the driver operation.<\/div>\n
\u2015 High ATF temperature mode: When the ATF temperature rises to a high temperature, the engine torque is restricted so that the increase in ATF temperature is suppressed to protect the transaxle.<\/div>\n
\u2015 Low engine coolant temperature mode: If the engine coolant temperature is low, a gear lower than when in normal mode is selected.<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
\n
AAS (Active Adaptive Shift) mode operation<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 Accelerator pedal fully closed suddenly and returned<\/div>\n
\n
\n
\u2015 When the accelerator pedal is fully closed and returned at a certain speed or more, shift-up is inhibited for specified time to improve speed control and acceleration performance.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Brake is strongly depressed<\/div>\n
\n
\n
\u2015 When decelerating at a certain speed or more, a lower gear is selected so that acceleration is performed smoothly.<\/div>\n
\u2015 During a shift change with the brake pedal depressed firmly, blipping control (synchronization to engine speed) is performed to shorten the shifting time.<\/div>\n
\u2015 The shift down control using the brakes may not operate under cold temperature condition.<\/div>\n
\u2015 When driving on slippery roads such as snow covered roads, the shift down control using the brakes may not operate.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 When cornering<\/div>\n
\n
\n
\u2015 While cornering at a turn with a radius of less than a specified value, shift up is suppressed to improve vehicle speed performance while cornering and acceleration performance after cornering.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 During drive in a high-altitude area<\/div>\n
\n
\n
\u2015 While driving in a high-altitude area, gears are selected appropriate to the driving conditions for driving comfort.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 During ascent<\/div>\n
\n
\n
\u2015 While ascending a slope of a certain grade or more, slope mode control prevents unnecessary shift-up by maintaining the appropriate gear.<\/div>\n<\/dd>\n<\/dl>\n
\u2022 During descent<\/div>\n
\n
\n
\u2015 While descending a slope of a certain grade or more and depressing the brake pedal, the gears are appropriately shifted down according to the estimated slope angle for effective use of engine braking. As a result, frequent brake pedal operation is reduced.<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 When SPORT mode is selected, the AAS selects a lower gear compared to when normal mode is selected, and maintains it for a longer period of time.<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
AAS (active adaptive shift) operation scenario and effect<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 The AAS (active adaptive shift) is a mode which estimates the driving environment and driver\u2019s intentions according to the vehicle driving conditions and the driver\u2019s operations, and selects the optimum gear for driving.<\/div>\n
\n
\n
Ex.1: Cornering<\/div>\n<\/dd>\n
\n
\u2015 During cornering, shift up is suppressed to improve acceleration performance after cornering.<\/p>\n\n\n\n

\n
\n
Ex. 2) Merging onto high speed expressways<\/div>\n<\/dd>\n
\n
\u2015 In a scenario such as temporarily decelerating while merging onto a high speed expressway, shift up is suppressed directly afterwards to improve acceleration performance.<\/p>\n\n\n\n
