<p><P>PROBLEM TO BE SOLVED: To maintain good startability without giving a drive unnatural feeling by preventing occurrence of hesitation even in a vehicle including two voltage systems and an electric heating catalyst. <P>SOLUTION: An ECU 50 outputs target voltage to execute charge without directly controlling power generation torque of a motor generator 4 at a time of charge. Since a high voltage battery 2 is charged by regeneration or the like, the high voltage battery is normally charged predetermined voltage value equivalent to 70% of battery residual capacity. If the vehicle is started within a first established time predetermined longer than energization time of a heater 11b from start of enerzigation of the heater 11b of the electric heating catalyst 11 when the ECU 50 energizes the heater 11b of the electric heating catalyst 11, target voltage for charge is established lower than normal established value until a predetermined second established time passes from start. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
