Abstract:
A vehicle driving apparatus comprising:a synchronous AC generator driven by a prime mover for driving a first axle of a vehicle, said synchronous AC generator having a field winding and an armature winding for generating electromotive force by magnetic flux generated from said field winding; an auxiliary generator driven by said prime mover, for charging an auxiliary battery; an induction motor driven by an output of said synchronous AC generator, for driving a second axle of the vehicle, said induction motor having an armature winding with the same number of phases as the armature winding of said synchronous AC generator; a connection wire connecting said armature winding of said synchronous AC generator and said armature winding of said induction motor; and a control device for controlling said synchronous AC generator, which control device controls a current flowing into said field winding of said synchronous AC generator to make voltage applied to said induction motor variable, thereby controlling torque generated in said induction motor.
