Abstract: An extrusion molding method utilizes a mandrel with a small outer diameter region having an outer diameter corresponding to a raw pipe inner diameter and a large outer diameter region having a larger outer diameter than the raw pipe inner diameter on its tip and base end sides respectively. The mandrel is pushed into the raw pipe set in a container which has a small inner diameter region having an inner diameter smaller than a raw pipe outer diameter and a large inner diameter region which has a larger inner diameter than the raw pipe outer diameter on its tip and base end sides respectively to expand a diameter of raw pipe end part on a base end side of the raw pipe. Thereafter, the base end side of the raw pipe having the mandrel inserted inside is pushed into the small inner diameter region of the container.

Abstract: A lane-dividing line recognition apparatus for a vehicle includes a processor that calculates relative coordinates of a tentative complementary point extracted from data on a lane-dividing line recognized in each predetermined cycle, based on image of a traveling environment in front of the vehicle, calculates a first lane-dividing line complementary point, based on the relative coordinates and traveling information on the vehicle, and calculates a second lane-dividing line complementary point, based on the relative coordinates and absolute position data on the vehicle.

Abstract: In extrusion processing in which diameter reduction is performed by pressing a raw pipe having a core bar inserted therein into a die having a small inner diameter portion on its tip end side, a differential thickness pipe having a thick-walled portion at its tip end can be molded using a core bar having a small cross-section portion formed at its tip end. It is also possible to mold a differential thickness pipe having a thick-walled part at an intermediate axial position by using a raw pipe having a thin-walled portion at its tip end. For example, such a raw pipe can be molded by extrusion processing using a core bar having no small cross section portion at its tip end, prior to the above-described formation of the thick-walled portion. When higher dimensional accuracy is required, a so-called “counter punch” may be used in the formation of the thick-walled portion.

Abstract: A vehicle drive assist apparatus for a vehicle includes: a forward environment recognition device configured to acquire forward environment information of the vehicle; a lateral environment recognition device configured to acquire lateral environment information of the vehicle; an alarm device configured to alert a driver who drives the vehicle through at least an alarm or a warning display; and a control unit configured to receive surrounding environment information including the forward environment information and the lateral environment information and activate the alarm device. The control unit is configured to compute a cognitive load value of the driver based on an object detected within a cognitive field-of-view area of the driver extracted from the surrounding environment information, and, in accordance with the cognitive load value, variably set a warning level of the alarm device to be activated upon detection of a potential collision object in the lateral environment information.

Abstract: An automated parking control device includes: a surrounding environment recognition device that acquires surrounding environment information of a vehicle; a parking controller that searches for an available parking area, generate a target route to the available parking area, and control the vehicle to move along the target route; an image processor that estimate a distance to a three-dimensional object and a slippage level of a road surface; an image map generator that generate a road a slippage level map; a wheel selector that predicts routes of vehicle's wheels, superimposes the routes on the map, and selects a wheel expected to pass through a route where the wheel is most unlikely to slip; and a movement amount calculator that acquires a wheel speed pulse of the selected wheel and calculates a movement amount of a reference position of the vehicle.

Abstract: A clamp member and a counter pressure member are hingedly connected together about a rotary axis, and a fitting portion of a fitting protrusion that is positioned in a fitting recess is located at a foreside in an advancing direction of the pipe relative to a position where a bending operation of the pipe is initiated, and a mating portion at which a first groove part of the clamp member and a second groove part of a counter pressure member mate is located at a backside in the advancing direction of the pipe relative to the position where the bending operation of the pipe is initiated. The counter pressure member comprises a first member supported rotatably about the rotary axis, a second member detachably connected to the first member, and a third member detachably connected to the second member, which are connected together by a common connecting member (e.g., bolt).

Abstract: A pipe bend die unit comprises a clamp member having a first groove part of half-circular cross section on an outer peripheral surface thereof with a fitting recess extending in a peripheral direction by a first predetermined length on a planar surface perpendicular to a rotary axis, and a counter pressure member having a second groove part of half-circular cross section formed on an outer peripheral surface thereof, and a fitting protrusion extending in a peripheral direction by a second predetermined length from a tip end portion of the second groove part. The fitting protrusion is positioned in the fitting recess so that the first and second groove parts are combined to form a pipe-receiving groove of half-circular cross section. The counter pressure member and the clamp member are hingedly connected to one another so as to be rotatable relative to each other about the rotary axis.
