    Abstract: A vehicle traveling control system and a vehicle control device whereby markers are detected with reliability and information about a local vehicle is transmitted to a succeeding vehicle. Information collecting unit of a preceding vehicle acquires information about the traveling state of the local vehicle associated therewith and supplies the acquired information to modulating unit. The modulating unit modulates the information supplied thereto and supplies the modulated information to blinking unit. The blinking unit causes the markers to blink in accordance with the information supplied thereto. Imaging unit of the succeeding vehicle acquires images of the markers and supplies the acquired images to specifying unit. The specifying unit specifies the marker images from within the image data output from the imaging unit. Validity determining unit determines validity of the specified marker images. Using the marker images, distance measuring unit measures a distance to the preceding vehicle. Demodulating unit demodulates information superimposed on the markers to reproduce the original information. In accordance with the information obtained from the distance measuring unit and the demodulating unit, control unit controls the traveling state of the local vehicle associated therewith.

    Abstract: A vehicle control device generates a speed pattern alternately repeating an acceleration travel pattern having a section accelerating a host vehicle and an inertia travel pattern having a section with an acceleration driving force of zero and a deceleration braking force of zero with respect to the wheels of the host vehicle. The speed pattern is generated by reducing speed of the host vehicle in front of any one position of an intersection of the road on which the host vehicle travels and an exit leading to the road. The intersection and the exit may encounter another vehicle, and may include a traffic flow of other vehicles on a road with a host vehicle. Matching a proved speed by reducing vehicle speed of a speed pattern with a position of an intersection or an exit, the host vehicle may cooperate with traffic flow to improve fuel efficiency.

    Abstract: Disclosed is a vehicle control device capable of reducing calculation time while securing precision of a traveling plan in an arbitrary section. The vehicle control device controls a vehicle along a traveling plan calculated in accordance with a traveling path to a destination of the vehicle. The vehicle control device includes a traveling path setting unit which sets the traveling path from the current position of the vehicle to the destination, a traveling path division unit which divides the traveling path into a first section and a second section, and a traveling plan calculation unit which calculates a first traveling plan according to the first section and a second traveling plan according to the second section. The traveling plan calculation unit coarsens calculation granularity in the second traveling plan compared to calculation granularity in the first traveling plan.

    Abstract: A steering control device for a vehicle includes a steering characteristic setting unit setting the range of a steering manipulation angle corresponding to a tire angle in a predetermined range (near an induction target tire angle for guiding to a target locus), which is determined on the basis of the target locus upon vehicle traveling, to be wider than the range of a steering manipulation angle corresponding to a tire angle outside of the predetermined range. A reduction gear ratio of a steering mechanism in the predetermined range increases.
