Claims

[Scope of utility model registration request]

a motor that is independently rotatable in forward and reverse directions for each drive wheel of the automobile; a vehicle speed control unit that generates a rotation speed control signal that duty-controls the rotation speed of each motor according to the amount of depression of an accelerator pedal; provided for each motor capable of forward and reverse rotation,
A drive circuit that converts the rotational speed control signal from the vehicle speed control section into a motor drive current and rotates the motor forward or reverse; and a drive circuit that is provided between the vehicle speed control section and the drive circuit and selects forward, reverse, or neutral. and a drive motor selector, which is also provided between the vehicle speed control section and the output circuit, and selects drive of the right motor, drive of the left motor, or simultaneous drive of both left and right motors depending on the rotation angle of the steering wheel. What is claimed is: 1. A drive wheel independent drive control device for an automobile, comprising:
