<P>PROBLEM TO BE SOLVED: To provide a control device for hybrid vehicle that is capable of controlling an electric storage device to the maximum allowable voltage of the electric storage device when charged and to the minimum allowable voltage when discharged without exceeding the maximum allowable voltage or the minimum allowable voltage. <P>SOLUTION: A reference value for instruction torque for a motor-generator is computed by a reference instruction torque computation unit 61. When the voltage of an electric storage device approaches its maximum allowable voltage Vmax and when the voltage approaches its minimum allowable voltage Vmin, the reference value for instruction torque is multiplied by a limit correction value to compute instruction torque. The instruction torque is corrected by multiplying it by the limit correction value when the voltage is between the maximum allowable voltage Vmax and a threshold value Vs and when the voltage is between the minimum allowable voltage Vmin and the threshold value Vs. The threshold values Vs for charging and for discharging are respectively computed based on a reference value set according to the current of the electric storage device and temperature and a correction value set according to the remaining capacity of the electric storage device and its current. <P>COPYRIGHT: (C)2008,JPO&INPIT |
