Patent ID: 7788010

Claim:
A controlling system of a vehicle provided with a continuously variable transmission, which calculates a target rotation speed calculated relative to an input shaft rotation speed of the continuously variable transmission and calculates a target output torque of a power source to achieve a target drive force calculated based on an output requirement amount and a vehicle speed, for controlling a speed change ratio of the continuously variable transmission based on the target rotation speed, comprising: an acceleration requirement judging means for judging an acceleration requirement by a driver; and a controlling means, upon judgment of the acceleration requirement by the acceleration requirement judging means, for setting a target drive force upon acceleration to be higher than the target drive force calculated, for further maintaining or decreasing the target drive force relative to an increase of the vehicle speed, for setting a target rotation speed upon acceleration higher than the target rotation speed calculated, and for increasing the target rotation speed with an increase of the vehicle speed by a predetermined gradient, to thereby control the speed change ratio of the continuously variable transmission and the output torque of the power source such that the target drive force set upon acceleration is achieved and the input shaft rotation speed of the continuously variable transmission coincides with the target rotation speed upon acceleration.
