<P>PROBLEM TO BE SOLVED: To provide motor warm-up control for reducing power consumption due to an increase in temperature of a lubricating oil without changing an operation mode of a motor and a power transmission means. <P>SOLUTION: The motor warm-up control includes a temperature detection means 75 of detecting a temperature at a predetermined position, a rotational speed detection means 25 of detecting a rotational speed of the motor, a friction torque estimation means of estimating friction torque T2 of a gear, a pedaling torque calculation means of calculating a pedaling torque T1 to the motor based on an amount of pedaling of an accelerator pedal 61, a correction torque calculation means of calculating a correction torque T3 based on the friction torque and pedaling torque, and a lubricating oil temperature increase means of controlling an inverter by the correction torque to supply a current corresponding to the correction torque to the motor and increasing the temperature of the lubricating oil while ensuring the pedaling torque. In executing the lubricating oil temperature increase means, the setting is made as a limiting value of an output power value of an energy storage device based on what is obtained by performing power conversion of the correction torque. <P>COPYRIGHT: (C)2011,JPO&INPIT |
