<P>PROBLEM TO BE SOLVED: To provide a drive control device for an electromotive vehicle capable of detecting the abnormality of a temperature-detecting means, while preventing a malfunction of a motor. <P>SOLUTION: The drive control device 1 for an electromotive vehicle decides target torque and supplies AC power to a motor coil, to generate the target torque to drive and control a drive motor 2. The device 1 detects the temperature of the drive motor 2 and estimates the voltage value applied to the motor coil based on the detected temperature of the drive motor 2, the value of the current flowing to the motor coil and a map showing the correlation between the temperature and the resistance value of the motor coil. The drive control device 1 for an electromotive vehicle detects the voltage applied to the motor coil and detects the malfunction of a motor temperature detecting part 17 when the difference between the detected voltage value and the estimated voltage value is larger than a specified value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
