Technical Examples
A lock-up clutch controlling device includes a three-dimensional back pressure map, a sensor, and a lock-up pressure controlling unit. The map allows a back pressure of a lock-up piston to be determined from a rotational speed of an engine, an oil temperature, and a speed ratio. The sensor is provided for a parameter influencing the back pressure of the piston. The lock-up pressure controlling unit determines a value equivalent to the back pressure of the lock-up piston from an input value of the sensor and the hydraulic pressure map, and outputs a lock-up pressure to be applied to a lock-up clutch by using the value equivalent to the back pressure of the lock-up piston. When the controlling device operates, it outputs the lock-up pressure by using the value equivalent to the back pressure of the lock-up piston.
