A sensor equipped axle unit having an in-wheel type motor built therein, in which a hub bearing assembly (A), an electric motor (B), a reduction gear unit (C) and a brake assembly (D) are arranged coaxially on a center axis of a vehicle drive wheel. Sensors (80, 81 and 82) are provided for measuring forces Fx, Fy and Fz acting at a point of contact of the vehicle drive wheel (70) and a road surface in three axis directions perpendicular to each other, respectively, from the status of at least one of the hub bearing assembly (A), the electric motor (B), the reduction gear unit (C) and the brake assembly (D). Results of such measurement are utilized for a suspension control, an ABS control and any other control. |
