Abstract: A vehicle control device includes a detection unit detecting a preceding vehicle based on an image acquired by a camera, a follow-on travel control unit that can control a user's own vehicle to travel so as to follow the preceding vehicle, and can control the user's own vehicle to travel at a predetermined speed when the preceding vehicle does not exist, and an acceleration suppression unit suppressing acceleration of the user's own vehicle for a predetermined time period if a detection accuracy for the preceding vehicle is decreased in the detection unit when the user's own vehicle is following the preceding vehicle at the predetermined speed or less. The predetermined time period is a vehicle headway time previously determined for the preceding vehicle or a time required until the user's own vehicle reaches a location where the preceding vehicle was positioned when the detection accuracy was decreased.

Abstract: A column and beam connection structure for connecting a steel H-beam to a column uses an external diaphragm. The external diaphragm includes a plurality of divided diaphragm segments such that each diaphragm segment has a column plate abutting on the column. A diaphragm segment which is arranged along the steel H-beam among the plurality of divided diaphragm segments has a beam plate installed in a flange of the steel H-beam. The beam plate has an end portion in which the column plate is provided. A joining surface between the diaphragm segments is placed in a vicinity of a corner portion of the column so that only the column plate of one of the diaphragm segments abuts on each column surface of the column. A joining member fastens to fix between the diaphragm segments such that contact pressure is applied from the column plates to the surface of the column.

Abstract: When a start-up operation by a driver is detected while a vehicle is maintained at a stopped state, a target driving force for suppressing the movement of the vehicle on the road to be driven is calculated, based on the grade obtained regarding the road to be driven on. After the vehicle is driven by the target driving force, the braking force is released so as to terminate the maintaining of the stopped state of the vehicle. Preferably, the state of being driven by the target driving force is maintained until the releasing of the braking force is completed. When the releasing of the braking force is completed, the driving force is increased to start-up the vehicle. With such a start-up control, vehicles are prevented from moving temporarily in a direction opposite from the traveling direction, and a smooth star-up can be achieved.

Abstract: In a control system for an internal combustion engine having a plurality of cylinders and mounted on a vehicle, in which the engine operation is switched based on the throttle opening between a full-cylinder operation in which all of the cylinders are operative and a cut-off cylinder operation in which some of the cylinders are inoperative, and a running control including a cruise control in which the vehicle runs at a desired vehicle velocity and a preceding vehicle follow-up control in which the vehicle runs at a desired vehicle velocity to maintain a desired inter-vehicle distance from a preceding vehicle are conducted. In the system, an acceleration suppression control is conducted if the engine operation is switched from the cut-off cylinder operation to the full-cylinder operation when the running control is in progress. With this, sharp or drastic acceleration accompanying torque fluctuation is effectively avoided, when the engine operation is switched to the full-cylinder operation.
