Claim Text:
1. A control apparatus for a vehicle comprising a continuously variable transmission configured to transmit power from a drive power source toward a drive wheel, the control apparatus performing a gear ratio control for determining a target gear ratio of the continuously variable transmission based on a required driving force to be required at re-acceleration, the required driving force to be required at re-acceleration being set to be greater as a deceleration of the vehicle while decelerating is more increased, wherein the control apparatus is configured to: estimate a basic required driving force to be required at re-acceleration or a value correlated with the basic required driving force from the deceleration of the vehicle while decelerating; correct the basic required driving force or the value correlated with the basic required driving force based on: a maximum amount of vehicle speed change calculated by multiplication of a maximum deceleration in a period from a start of the gear ratio control initiated upon establishment of a predetermined condition for initiating the gear ratio control up to a current time point by an elapsed time from the start of the gear ratio control initiated upon the establishment of the predetermined condition for initiating the gear ratio control up to the current time point; and an amount of vehicle speed change from the start of the gear ratio control initiated upon the establishment of the predetermined condition for initiating the gear ratio control up to the current time point to obtain the required driving force to be required at re-acceleration or the value correlated with the required driving force; and determine the target gear ratio of the continuously variable transmission based on the required driving force to be required at re-acceleration or the value correlated with the required driving force.
