Patent ID: 7011602

Claim:
A shift control apparatus comprising: a continuously-variable transmission; a sensing section to sense a vehicle speed of a vehicle and an accelerator operation condition of the vehicle; and a controller to control an actual transmission ratio of the continuously-variable transmission normally in a first mode in accordance with the vehicle speed and accelerator operation condition, to produce a rapid acceleration request signal by monitoring an accelerator operation speed determined from the accelerator operation condition, to control the actual transmission ratio of the continuously-variable transmission in a second mode in response to the rapid acceleration request signal, by varying a target transmission ratio, to determine a second-mode downshift characteristic and a second-mode upshift characteristic in accordance with the accelerator operation condition, and to control the actual transmission ratio of the continuously-variable transmission in the second mode in response to the rapid acceleration request signal by performing a downshift operation to a target downshift transmission ratio determined according to the second-mode downshift characteristic and an upshift operation according to the second mode upshift characteristic.
