<P>PROBLEM TO BE SOLVED: To obtain stable travel state responding to the opening of an accelerator so as to cope with the slip state of a drive wheel, even in a travel only by the output of a rotary electric machine, in a parallel hybrid system. <P>SOLUTION: This hybrid system is equipped with a means 30, which controls the torque command value of a rotary electric machine into the requested torque equivalent to that in the travel by only the output of an engine, during the travel by only the output of the rotary electric machine, a means 31 which computes the rotational acceleration from the rotational speed of the rotary electric machine, a means 32 which computes the inertia torque falling upon the drive shaft of the rotary electric machine from the rotational acceleration of the rotary electric machine and the drive system of the engine, a means 33 which detects the slippage state of a drive wheel, and a means 34 which corrects the torque command value of the rotary electric machine from the demanded torque in the travel, by only the output of the rotary electric machine and the inertia torque falling upon the drive shaft of the rotary electric machine, when the drive wheel is in slip state from the decision and also gives a response delay equivalent to that of the engine to the output characteristics. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
