<p><P>PROBLEM TO BE SOLVED: To prevent excessive charging and discharging of an energy storage device, which occur by command value change delay due to transmission delay between controllers when rotational speed of a rotating electrical machine suddenly changes, in an electric vehicle in which the controller generating an input/output power command value of the energy storage device and the controller controlling a power conversion device and the rotating electrical machine are individually arranged. <P>SOLUTION: The controller MG-ECU22 detecting rotational speed of the rotating electrical machine MG2 corrects the input/output power command value of the energy storage devices 10-1 and 10-2, which is set by HV-ECU21 in an original case, in accordance with a change of rotational speed of the rotating electrical machine MG2 without waiting for the change of the input/output power command value from HV-ECU 21 when rotational speed of the rotating electrical machine MG2 suddenly changes. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
