<P>PROBLEM TO BE SOLVED: To prevent a motor coil from burning out by preventing temperature in the motor coil from being raised to critical temperature. <P>SOLUTION: In a case where the end of gear change has been decided by a gear change end decision means 123 for deciding if a transmission 102 has undergone the gear change, a control device of the transmission measures coil resistance value of motors 109, 110 operating the transmission 102 by a coil resistance measurement means 116. The control device estimates coil temperature of the motors 109, 110 from the measured coil resistance value of the motors 109, 110 by a coil temperature estimation means 117. In a case where the estimated coil temperature of the motors 109, 110 has been decided to be predetermined temperature or above by a high-temperature decision means 118, the control device calculates speed change inhibition time period of the transmission 102 by a speed change inhibition time calculation means 119 and inhibits the speed change of the transmission 102 during the calculated speed change inhibition time period. <P>COPYRIGHT: (C)2010,JPO&INPIT |
