Ecu device, vehicle seat, system for estimating lower limb length of seated person, and attachment structure for sitting height detection sensor

Abstract

Provided is an ECU device for estimating a length of the lower limbs of a seated person seated on a vehicle seat, the ECU device comprising: a thigh angle information acquisition means for acquiring information pertaining to a thigh angle (θ) of the seated person; a back-of-knee angle information acquisition means for acquiring information pertaining to a back-of-knee angle (φ) of the seated person; and an estimation means for estimating a length (z) of the lower limbs of the seated person on the basis of the information pertaining to the thigh angle (θ) acquired by the thigh angle information acquisition means and the information pertaining to the back-of-knee angle (φ) acquired by the back-of-knee angle information acquisition means. Through this configuration, the length of the lower limbs of a seated person seated on a vehicle seat can be accurately estimated.
