SHIFT POINT CONTROL [FW6A-EL]


id057000000600


Purpose of Adoption

•  For effective use of engine braking, engine speed is increased during manual down shifting with the accelerator fully open, during strong braking while in D position, and while braking on down slopes, without having to depress the accelerator.
•  To improve responsiveness during re-acceleration, if the accelerator is suddenly released such as when merging onto highways or when cornering, up-shifting is put on standby for several seconds.
•  If a lack of drive force relative to the drive resistance on an up-slope is calculated, shift-up is suppressed even if the accelerator pedal is released, to assure vehicle speed performance and to prevent frequent shifting.
•  If a lack of engine braking force relative to the increase in vehicle speed on a down- slope is calculated, down-shifting is implemented in conjunction with the brake pedal operation to assure engine braking force and reduce the frequency in which the brake pedal is operated.
•  If cornering in which comparatively high lateral G-force occurs is determined, up-shifting is temporarily inhibited to improve responsiveness during re-acceleration when exiting a corner.
•  When decelerating using strong brake force upon entering a corner, down-shifting is performed to improve responsiveness during re-acceleration when exiting the corner.
•  To improve fuel economy, the transmission is put into pseudo-N position while the vehicle is stopped and in D position. However, on a grade exceeding +/- 5%, the control is not operated.

Common Inquiry

•  If there is a claim from a user concerning engine idling for increasing the engine speed without having to depress the accelerator, such as during manual down-shifting with the accelerator fully open, during strong braking while in D position, and while braking on down- slopes, explain the content of the repair order form and give the user appropriate advice.
