AUTOMATIC SHIFT CONTROL OUTLINE [DJVA-EL]

Automatic Shift Control
• The CVT shift control sets the target input shaft rotation speed in the TCM based on information such as the throttle opening angle, vehicle speed, and brake signal so that the optimum gear ratio and shift speed are obtained. Also, to optimize the gear ratio, it also outputs signals to shift control solenoids No.1 and No.2 so that the rotation speed obtained from the target input shaft rotation speed and the actual rotation speed from the primary pulley speed sensor match.
Ascent Mode
-
• When the vehicle is driven on an up slope, the TCM determines that the vehicle is on an up slope based on the signal from the PCM and the output rotation speed, and automatically switches the driving mode to ascent mode. As a result, traction reduction is prevented.
Descent Mode
-
• When the vehicle is driven on a down slope, the TCM determines that the vehicle is on a down slope based on the signal from the PCM and the output rotation speed, and automatically switches the driving mode to descent mode. As a result, optimum engine braking occurs.
D Range Shifting
• Controls the gear ratio to obtain both fuel economy and driving performance based on information such as the throttle opening angle and vehicle speed.
SS Mode Shifting
• When the SS mode switch is pressed, the shift control range on acceleration side is restricted, optimum engine braking occurs, excellent shifting response is realized, and crisp and precise driving is possible.
L Range Shifting
• Powerful engine braking is possible because the shift control range is set to the maximum deceleration side.
