    摘要: A road surface condition estimation device (200) includes a control circuit (201), an acquisition circuit (202) and an estimation circuit (203). The control circuit (201) is configured to control a driving device that is able to independently drive a plurality of wheels. The acquisition circuit (202) is configured to acquire detection results of a plurality of wheel speed sensors that detects rotation speeds of the plurality of wheels respectively. The estimation circuit (203) is configured to calculate a slip ratio for each driving wheel, based on a detection result of a first wheel speed sensor and a detection result of a second wheel sensor. The estimation circuit (203) is configured to estimate a friction coefficient for each region on a road surface that corresponds to the driving wheel, based on the slip ratio.

    摘要: A manufacturing process (S1) for a stator (1) includes: an arrangement process (S12) of arranging at least either conductor side portions (41) of a first segment conductor (5) or conductor side portions (41) of a second segment conductor (6) in slots (21) such that a facing surface (44) of one of joint portions (43) of the first segment conductor (5) and a facing surface (44) of one of joint portions (43) of the second segment conductor (6) face each other; a regulation process (S15) of regulating movement of the conductor side portions (41) in the radial direction (R); and a joint process (S14) of joining the joint portions (43) of the first segment conductor (5) and the joint portions (43) of the second segment conductor (6) to each other by pressing at least one of the first segment conductor (5) and the second segment conductor (6) in the axial direction (L) such that the first segment conductor (5) and the second segment conductor (6) approach each other while maintaining a regulating state in the regulation process (S15).
