PURPOSE:To prevent learning which is carried out using a measured value in the course of speed change in a throttle opening range less than a reference value, and has the possibility of insufficient pertinence. CONSTITUTION:An input-output revolution sensor detects the number of input- output revolutions of the speed change gear mechanism of an automatic speed change gear which actuates the various friction elements of the speed change gear mechanism by line pressure to carry out speed change, and a measuring means for inertia phase time measures the inertia phase time being time when a ratio between the numbers of input-output revolutions is varying, and a line pressure regulating means regulates the line pressure on the data of correction quantity, and corrects the above data using the measured value of the inertia phase time. A throttle opening output means detects and outputs a throttle opening in carrying out speed change, and only in the case where the throttle opening in the case of speed change is more than a reference value, a correct- restricting means for the data of correction quantity allows the correction of the data of correction quantity which is carried out using the measured value of the inertia phase time during the speed change on the basis of a signal issued from the throttle opening output means. |
