  • Patent number: 9845093
    Abstract: A vehicle speed limiting apparatus includes an opening detection unit to detect an opening of an accelerator pedal of the vehicle; an estimation unit to estimate whether the vehicle starts a lane change; and an ECU to implement an upper-limit setting unit to set an upper-limit speed of the vehicle, a vehicle speed control unit to control the traveling speed so as not to exceed the upper-limit speed even when the opening of the accelerator pedal becomes great enough to make the traveling speed exceed the upper-limit speed, and a permissible speed setting unit to set a permissible speed higher than the upper-limit speed. When the estimation unit estimates that the vehicle starts the lane change, the vehicle speed control unit permits the traveling speed to exceed the upper-limit speed, and controls the traveling speed so as not to exceed the permissible speed.

  • Publication number: 20170144664
    Abstract: A vehicle control device which can substantially eliminate or shorten a period when vehicle speed exceeds a lowered speed limit when a vehicle goes into a road where a speed limit lower than before then during running of the vehicle should be provided. A speed control decreases vehicle speed so that the vehicle speed approaches the next speed limit from a time point when it is judged that a position of the own-vehicle is at a predetermined position in front of a transition point which is a point where the next speed limit starts to be applied, in a case where a specified condition that the next speed limit is lower than the present speed limit is satisfied.

  • Publication number: 20170140922
    Abstract: Disclosed is a method of generating a recipe for supplying an imprint material onto a substrate, the imprint material being used in imprint processing of forming a pattern on the substrate with the imprint material and a mold. The method includes obtaining first information about a volume of a pattern of the mold, and obtaining second information about a concentration of a condensable gas to be supplied to a space between the mold and the imprint material on the substrate. The condensable gas has a property of being liquefied by contact between the mold and the imprint material. The method further includes generating the recipe based on the first information and the second information.

  • Publication number: 20160347313
    Abstract: A control system for a vehicle includes an imaging device; a co-ECU to limit the travel speed of the vehicle; and an ECU to set the speed limit, that recognizes the speed limit value on a road while traveling, and sets the recognized speed limit value in the co-ECU. If the elapsed time since the speed limit value has been set reaches a predetermined time, the ECU estimates the speed limit value on the road while traveling, and if receiving a switch command, switches the speed limit value set in the co-ECU to the estimated speed limit value so as to avoid limiting the vehicle speed by a speed limit value that is different from the actual speed limit value on the road.

  • Publication number: 20160347175
    Abstract: A vehicle's accelerator pedal depression amount is detected; a speed limit of a road on which the vehicle is traveling is determined; a start of a lane change is estimated; an upper-limit speed is determined each time when the speed limit changes; and the travelling speed is controlled to not exceed the upper-limit speed even if the accelerator pedal depression amount increases to cause the speed of the vehicle to exceed the upper-limit speed. The speed of the vehicle is controlled, until a predetermined timing, to not exceed the upper-limit speed determined before the start of a lane change is estimated, if (i) the start of a lane change is estimated, and (ii) a reduction in the speed limit is determined. After the predetermined timing, the speed of the vehicle is controlled to not exceed the currently determined upper-limit speed.
