<p><P>PROBLEM TO BE SOLVED: To suppress vehicle vibration caused by a torque fluctuation due to battery voltage fluctuation. <P>SOLUTION: An electric vehicle is power run by an electric power supplied from a battery, and is braked by regeneration to the battery. When a time period from a torque restriction start t<SB POS="POST">0</SB>due to a battery voltage fluctuation is in a predetermined time range±αfrom 1/2ωhalf of a natural period of a torsional vibration in a drive system, a torque restriction is not released. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
