Hybrid car and control apparatus therefor, and hybrid four-wheel-drive car and control apparatus therefor

Abstract

In a hybrid car, or an electric motor-driven four-wheel-drive vehicle, in which an electric motor is driven directly by an output from a generator, vehicle running performance is enhanced. The output from the generator is controlled so as to maintain a generator torque in a range, in which the vehicle does not stall. Specifically, a driving apparatus for the hybrid car includes a second generator 2 driven by an engine 1 for driving one pair of either front or rear wheels 14, 15, an electric motor 5 driven through directly receiving the output from the second generator 2 and driving the other pair of either the front or rear wheels 14, 15, and a four-wheel-drive control unit 6 controlling driving of the second generator 2 and the electric motor 5. When the engine 1 is in an overloaded condition, the four-wheel-drive control unit 6 limits the output of the second generator 2.
