    • PROBLEM TO BE SOLVED: To improve driveability in the case of deceleration when making a drive force source brake torque act. SOLUTION: On the basis of motor efficiency ηm, alternator efficiency ηa for 4WD, and a power loss Pw/h(-) of a wire harness 28, alternator drive torque Ta for 4WD is calculated so that, when making drive force source brake torque TB act by a drive force source (engine 14 and motor 20), the alternator drive torque Ta for 4WD for offsetting a portion TBer of engine brake torque TBe can be precisely calculated. Thus, it is possible to make the actual drive force source brake torque TB appropriately act so as to match the target drive force source brake torque TB*, and to appropriately perform the braking force distribution of total drive force source brake torque TB with front wheel brake torque TBf which is made to act with the other section (excess section) TBef of the engine brake torque TBe and rear wheel brake torque TBr which is made to act with motor regenerative brake torque TBm.

    • PROBLEM TO BE SOLVED: To properly control the temperature of an exhaust emission control catalyst by utilizing a generator for supplying power to a motor in a driving force controller of a four-wheel drive car in which the driven wheels of a vehicle are driven by the motor.
      SOLUTION: In the four-wheel drive car, main drive wheels are driven by an internal combustion engine, and the driven wheels are driven by the motor. The second generator driven by the internal combustion engine when the driven wheels are driven to supply a power to the motor comprises a cooling fan which is disposed near the catalyst for purifying the exhaust gas of the internal combustion engine and which cools the second generator by introducing the outside air and blows air to the catalyst. The driving forces of the driven wheels are increased when the temperature T of the catalyst is lower than an activation temperature Ta (S120). When the temperature T of the catalyst is equal to or higher than a degradation temperature Tb, the driving forces of the driven wheels are lowered (S140).
