1. A drive system for a vehicle, the drive system comprising:
- a drive belt;
an engine selectively engageable with the drive belt;
a motor selectively engageable with the drive belt;
a supercharger for delivering compressed air to an intake of the engine, wherein the supercharger is selectively engageable with the motor; and
a controller for setting an operational mode of the drive system,wherein when in a power mode, the controller engages the engine with the drive belt, the controller engages the supercharger with the motor so as to deliver compressed air from the supercharger to the intake of the engine, and the controller disengages the motor from the drive belt; and
wherein when in a cruise mode, the controller disengages the engine from the drive belt, the controller engages the supercharger with the motor so as to deliver compressed air from the supercharger to the intake of the engine, and the controller engages the motor with the drive belt.

Abstract
A drive system includes a drive belt, an engine, a motor, and a supercharger for delivering compressed air to an intake of the engine, and a controller for setting the operational mode of the drive system. The engine and motor are selectively engageable with the drive belt, and the supercharger is selectively engageable with the motor. A method of controlling an operational mode of such a drive system includes detecting a throttle position. Thereafter, the method includes selectively engaging the engine with the drive belt or the drive belt with the motor or the motor with the supercharger, based at least in part on the throttle position.

11. A method of setting an operational mode of a drive system comprising a drive belt, an engine, a motor, and a supercharger for delivering compressed air to an intake of the engine, and a controller for setting the operational mode of the drive system, the method comprising:
-
wherein when in a power mode, the controller engages the engine with the drive belt, the controller engages the supercharger with the motor so as to deliver compressed air from the supercharger to the intake of the engine, and the controller disengages the motor from the drive belt; wherein when in a cruise mode, the controller disengages the engine from the drive belt, the controller engages the supercharger with the motor so as to deliver compressed air from the supercharger to the intake of the engine, and the controller engages the motor with the drive belt; wherein when in a regeneration mode, the controller engages the engine with the drive belt, the controller disengages the supercharger from the motor, and the controller engages the motor with the drive belt; and wherein when in an engine-off mode, the controller engages the motor from the drive belt, the controller disengages the supercharger from the motor, and the controller disengages the supercharger from the motor. - View Dependent Claims (12, 14, 15, 16)
