Abstract

A vehicle power assist system can be applied to a vehicle with a driven wheel () that is mechanically unconnected to a main drive source () such as an internal combustion engine. The driven wheel () is supported by a wheel support bearing assembly () to which a drive assist, motor generator () is mounted. A rotor of the motor generator () is directly fixed to a rotational ring of the wheel support bearing assembly () without interposition of a speed reducing mechanism or a speed increasing mechanism. The vehicle power assist system includes a power storage unit () configured to store a regenerative power generated by the motor generator () and to supply the stored power to the motor generator ().
