Shift control apparatus for continuously variable transmission

A shift control apparatus for a continuously variable transmission of a vehicle which is configured to continuously vary a rotational driving force of an engine that is inputted to an input side rotational member, and to transmit the varied rotational driving force to an output side rotational member, the shift control apparatus comprising:

• a target transmission gear ratio setting section configured to set a target transmission gear ratio based on an actual accelerator opening degree which is identified from an output signal of an accelerator operation amount sensor, and a vehicle speed;
• a shift control section configured to control a shift of the continuously variable transmission toward the target transmission gear ratio;
• a judging section configured to judge whether or not the vehicle runs an uphill;
• and
• a pseudo accelerator opening degree generating section configured to generate a pseudo accelerator opening degree which is larger than the actual accelerator opening degree when the actual accelerator opening degree is decreased when the judging section judges that the vehicle runs the uphill, and to output the pseudo accelerator opening degree to the target transmission gear ratio setting section,
• the target transmission gear ratio setting section being configured to set the target transmission gear ratio by using the pseudo accelerator opening degree when the pseudo accelerator opening degree is inputted, and
• the shift control section being configured to control the shift of the continuously variable transmission toward the target transmission gear ratio set based on the pseudo accelerator opening degree and the vehicle speed when the pseudo accelerator opening degree is generated, and to control the shift of the continuously variable transmission toward the target transmission gear ratio set based on the actual accelerator opening degree and the vehicle speed when the pseudo accelerator opening degree is not generated.
