Abstract: A tire tester includes a plurality of tire holding units attached to a movable member or a towed member and each configured to detachably hold a tire, and one or more load measuring units for measuring a load acting on the tire. The plurality of tire holding units include a first tire holding unit configured to detachably hold a first tire, and one or more second tire holding units each configured to detachably hold a second tire. The second tire holding unit holds the second tire to generate a force opposite to a lateral component force generated by steering the first tire. The tire holding units are arranged such that at least one tire holding unit is disposed on each right and left side of the movable member or the towed member with respect to a center line passing through a lateral center thereof.

Abstract: A steering holding determination device configured to determine whether a driver holds a steering member, the steering holding determination device including: a predicted value calculation unit configured to calculate a predicted value of at least one of one or more state quantities related to steering of the steering member and one or more state quantities related to turning of a wheel; and a steering holding determination unit configured to determine whether the driver holds the steering member with reference to the predicted value calculated by the predicted value calculation unit and a variance of the predicted value.

Abstract: A route generating device configured to generate a route includes a target route generating section (611) configured to generate a target route by connecting an initial location and a destination location through a line including a curve, a curvature of the curve generated by the target route generating section (611) is continuous along the curve.

Abstract: A steering holding determination device configured to determine whether a driver holds a steering member, the steering holding determination device including: a predicted value calculation unit configured to sequentially calculate a predicted value of a state quantity with reference to a steering torque and an actual measured value of the state quantity, the state quantity being related to a turning angle of a wheel; and a steering holding determination unit configured to determine whether the driver holds the steering member with reference to the predicted value calculated by the predicted value calculation unit and an actual measured value corresponding to the predicted value.
