Abstract: A travel control apparatus comprises a first detector configured to detect an obstacle around a subject vehicle traveling in a first lane and a second detector configured to detect a second lane adjacent to the first lane. The travel control apparatus sets a first range at a target position for lane change in the second lane. The first range has a size equal to or larger than a size which the subject vehicle occupies on a road surface. The travel control apparatus detects a range in the second lane as a second range. The range in the second lane is located at a side of the subject vehicle, and the obstacle is absent in the range in the second lane. The travel control apparatus permits the subject vehicle to change lanes when the second range includes the first range.
Abstract: A method is provided for manufacturing a terminal member that is electrical conductive with a conductive member. The terminal member is formed by working a workpiece having a plate shape with a first surface and a second surface extending from one end toward the other end, by cutting out a recessed portion at the one end from the first surface to the second surface. In this method, the recessed portion is supported by being abutted against a supporting member, and a portion spaced from the recessed portion toward the other end side is fixed, and both side portions along the one end from the recessed portion are bent while being pressed from the first surface toward the second surface side, thereby forming, as a pair of conductive surfaces for conduction with the conductive member, second surface portions facing each other with the supporting member interposed therebetween.

The device then acquires map information including landmark positions of landmarks existing on a map by the controller, matches the pieces of landmark position data in a certain range with the landmark positions included in the map information, and estimates the own position of the mobile body, the certain range being set based on movement records of the mobile body traveling to a current position.
Abstract: A scene understanding device obtains map data where one, two or more obstacle detection frames, shaped corresponding to a road structure, for detecting an obstacle are set in advance for a specific spot on a road where a vehicle would otherwise bump into a vehicle or a pedestrian. The scene understanding device determines whether there exists an obstacle in the obstacle detection frames set for the specific spot on a scheduled traveling route of a host vehicle, and calculates the degree of risk at the specific spot based on a result of determining whether there exists an obstacle therein.

Abstract: Metal foil base material placed on lower blade is first restricted under pressure by lower blade and pad and then cut by a shearing action based on an engagement of lower blade side cutting edge and upper blade side cutting edge. Resin face sheets are fixed to the top surface of lower blade and the pressing surface of pad, the face sheets having a larger friction coefficient than that of these surfaces. By frictional forces imparted by face sheets, metal foil base material is prevented from being dragged and moved by the pressing force of the upper blade prior to cutting. Consequently, the occurrence of “burr”, “roll-up”, and so forth is eliminated thereby ensuring a good cutting quality.
