摘要： When a gear change has been decided, the coil resistance value of a motor which manipulates the transmission is measured. The coil temperature of the motor is estimated from the measured coil resistance value of the motor. In a case where the estimated coil temperature of the motor has been decided to be a predetermined temperature or above, the speed change inhibition time period of the transmission is calculated, and the speed change of the transmission is inhibited during the calculated speed change inhibition time period.
