ABSTRACT:
In a vehicle drive system having a torque split arrangement, it is difficult to have all the rotating parts of the system to be properly balanced. In particular, when a rotational speed difference is produced between the two output elements, relatively massive parts which may not be properly balanced may have to be turned at a high speed. According to the present invention, because the power output of the engine is reduced whenever any significant speed difference is produced between the two output elements, no part of the drive system is subjected to any excessive rotational speed, and are therefore not required to have any excessive mechanical strength. This improves the reliability of the system, and reduces the manufacturing cost.
