ABSTRACT:
A drive mode selecting system for a four-wheel-drive motor vehicle includes a drive system for driving a first axle drive mechanism and a second axle drive mechanism, a clutch for selectively rigidly connecting the first and second axle drive mechanisms through the drive system for transmitting relative torque between the first and second axle drive mechanisms, and disconnecting the first and second axle drive mechanisms, a brake operation detector for detecting operation of a brake of the motor vehicle, an accelerator operation detector for detecting operation of an accelerator of the motor vehicle, and a controller responsive to detected signals from the brake operation detecting means and the accelerator operation detecting means for applying a disengaging signal to the clutch means to disconnect the first and second axle drive mechanisms when the detected signals indicate that the brake is operated and the accelerator is not operated.
