摘要： PROBLEM TO BE SOLVED: To improve response at a time of down shift in a high vehicle speed domain without influencing response at a time of down shift in a low vehicle speed domain in relation to speed change control device for a continuously variable automatic transmission. SOLUTION: This transmission control device for the continuously variable automatic transmission successively calculates a transient target speed ratio for an achieved speed ratio calculated according to a vehicle operation condition, performs speed change control toward the target speed ratio. A base time constant is established based on difference between the achieved speed ratio and the target speed ratio calculated in the last time, and a lower limit value of the base time constant is established according to vehicle speed. Larger value of these values is used to establish the target speed ratio in this time. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent failure in reducing shift shock with engine torque reducing/increasing control as intended, because of an insufficient torque reducing/increasing margin. SOLUTION: A gear ratio command value shown by a broken line is corrected to be a target gear ratio shown by a solid line by a shifting constant correcting coefficient so that a shift speed generates inertia releasing torque shown by a solid line which can just be counterbalanced by an engine torque reducing margin. The inertia releasing torque during shift at this shift speed is smaller as shown by the solid line, resulting from a lower shift speed, and an engine torque-down amount for counterbalancing it to reduce shift shock can be smaller, ΔTedn-α. To actualize engine torque tTe reflecting (ΔTedn-α) shown by a solid line, a throttle opening TVO is controlled as shown by a solid line. The tTe is surely achieved to completely counterbalance the inertia releasing torque shown by the solid line, thus reducing shift shock as intended. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent a control to limit a gear ratio from being operated under unintended situations while applying, to a vehicle without an ABS, a displacement limit control of the gear ratio to high side for securing start performance after wheel spin even if the wheel spin occurs after a vehicle start operation is performed in the shift control device and the shift control method for a continuously variable transmission. SOLUTION: In this shift control device of the continuously variable transmission 2 mounted on the vehicle without the ABS, when a drive wheel acceleration α acquired by a drive wheel acceleration acquiring means 13A is determined to be a preset accelerator or higher while the vehicle is running, a shift operation to transfer to the high side gear ratio at which the gear ratio of the continuously variable transmission is less than a preset first gear ratio is prohibited by a prohibition means 13C. The gear ratio at this point of determination is estimated by a gear ratio estimating means 13B by using the step position of a spepping motor 14a. When the gear ratio is lower than a preset second gear ratio, the shift operation by the prohibition means 13C is not prohibited. COPYRIGHT: (C)2007,JPO&INPIT
