Abstract
A control apparatus for a vehicle provided with (i) a power source, (ii) drive wheels and (iii) a fluid transmission device disposed between the power source and the drive wheels and including a lockup clutch to which a fluid pressure is supplied. A feedback control is executed for correcting a command value of the fluid pressure by a correction amount such that an actual value of a slip amount of the lockup clutch becomes substantially equal to the target value of the slip amount in a slip control. When the actual value has been converged into a given range with respect to the target value, the correction amount is obtained, and the command value for a next execution of the slip control is corrected by learning with use of the obtained correction amount. The given range is set depending on the target value of the slip amount.
