Here, A1 is the cross-sectional area of the wire (25) after compression. That is, A1 is the sum of the cross-sectional area of the each strand after compression. Also, 131 is the cross-sectional area of the covered area (27) after compression. In the present invention, the compression rate for the wire (25) is set between 50% and 80%. Also, the compression rate for the covered area (27) is set between 40% and 90%. The amount of compression by the molds (31a, 31b) is set so that the compression rates are within these ranges. In the present invention, the compression rate is calculated by: (cross-sectional area after compression)/(cross-sectional area before compression). That is, 80% compression rate means that the cross-sectional area has decreased by 20% due to compression. That is, the relationships of 80%?(A1/A0)?50% and 90%?(B1/B0)?40% are satisfied.

  • Publication number: 20180170315
    Abstract: A windscreen wiper control system controls a drive mechanism for at least one windscreen wiper arm to effect a reciprocating movement of the at least one windscreen wiper arm within a wiping range between a first position and a second position. The control system includes a detector that detects, upon activation of the control system, an uncertain position of the windscreen wiper arm within the wiping range but different from the first position. Upon detection of such an uncertain position, the control system returns the windscreen wiper arm to the first position at a predetermined reduced speed, the reduced speed being applied at least in a sub-range of the wiping range in the vicinity of the first position.

  • Publication number: 20180170371
    Abstract: A driving supporter includes: an object-information obtainer that obtains object information relating to at least an object in an area; an environment obtainer that obtains a relative positional relationship between the own vehicle and the object located in the area and identified based on the object information obtained by the object-information obtainer; and a support inhibitor that inhibits driving support when an absolute value of a steering operation value representing a magnitude of a steering operation is greater than an inhibition threshold value. The support inhibitor includes a threshold-value determiner that determines the inhibition threshold value to a smaller value when the relative positional relationship is a specific relationship in which it is estimated that a steering operation in a direction in which the own vehicle avoids the object is to be performed, than when the relative positional relationship is not the specific relationship.

    Abstract: A driving supporter includes an environment obtainer and a support controller configured to control a supporting device to perform driving support such that an own vehicle travels along a target traveling line. The environment obtainer includes a relative-positional-relationship obtainer configured to obtain a relative positional relationship between the own vehicle and an object detected based on object information obtained by an object-information obtainer. The support controller includes an offset-target-traveling-line setter configured to set, when the relative positional relationship is a specific relationship in which it is estimated that a steering operation in a direction in which the own vehicle avoids the object is to be performed, the target traveling line to an offset position that is shifted in a direction identical to a direction of a steering operation from the target traveling line located when the relative positional relationship is not the specific relationship.

  • Publication number: 20180170364
    Abstract: A vehicle stability control device includes a yaw moment generation device and a control device. A variation yaw moment generated by simultaneous turn and acceleration/deceleration is expressed as a function of a longitudinal acceleration and a lateral acceleration. A longitudinal force and a lateral force of a tire have non-linear load dependency. The variation yaw moment when assuming that the load dependency is linear is a first variation yaw moment. The variation yaw moment considering the non-linear load dependency is a second variation yaw moment that is expressed as a product of the first variation yaw moment and a correction gain. In vehicle stability control, the control device controls the yaw moment generation device to generate a counter yaw moment counteracting the second variation yaw moment, based on the longitudinal acceleration, the lateral acceleration, and the correction gain.
