摘要： PROBLEM TO BE SOLVED: To provide a lock-up controller for a continuously variable transmission capable of conducting a lock-up control in a wide engine rotation range by providing smooth speed change in the lock-up control.
SOLUTION: The continuously variable transmission 10 has a lock-up ring 102 and a lock-up mechanism including a solenoid 101 for driving this. The control part 201 derives a lock-up ratio judging value with which the lock-up control is smoothly conductable from a lock-up ratio judging map 202 prepared in advance corresponding to current oil temperature based on signals of an Ne sensor 205 and a throttle opening sensor 206. An actual ratio calculation part 203 calculates a transmission ratio (actual ratio) that the continuously variable transmission 10 actually generates is calculated based on a signal of a vehicle speed sensor 204 and the Ne sensor 205. When the actual ratio becomes equal to the lock-up ratio judging value, the control part 201 reviews a movement quantity of a ratio variable means 104 and then executes the lock-up control by driving the solenoid 101.
