<P>PROBLEM TO BE SOLVED: To provide a motor control device that outputs a target braking torque and suppresses power to be regenerated to a battery, and to provide a vehicle system. <P>SOLUTION: The motor control device includes a carrier frequency selection unit for switching a mode between a first regenerative operation mode for supplying a first carrier frequency to an inverter and a second regenerative operation mode to be applied when instructions for suppressing a power generation quantity are input and supplying a second carrier frequency higher than the first carrier frequency to the inverter. Also, a carrier frequency capable of obtaining a target power generation amount may be selected based on a ratio between a kinetic energy input in the AC motor and output power generation amount by using a map capable of deriving the carrier frequency. <P>COPYRIGHT: (C)2011,JPO&INPIT |
