  • Publication number: 20140232265
    Abstract: When occurrence of a failure associated with light distribution control has been detected during high beam irradiation, a low beam irradiation direction is changed upward and then the high beam irradiation is stopped, and subsequently the low beam irradiation direction is gradually returned downward. The time during high beam irradiation includes the time during which variable high beam light distribution control in which part of high beam light is shielded by a shade is being executed.

  • Patent number: 8527095
    Abstract: A cooling system constructed to cool down an accumulator mounted on a motor vehicle is herein presented. The cooling system sequentially controls an air blower to restrict the air blow to the accumulator, controls the air blow mode switchover module to switch over the active air blow mode after restriction of the air blow to the accumulator, and controls the air blower to release the restriction of the air blow to the accumulator after the switchover of the active air blow mode by the air blow mode switchover module.

  • Patent number: 8265822
    Abstract: A disclosed in-vehicle equipment control device “S” includes input units 2 and 3 for increasing and decreasing a set value of in-vehicle equipment, and a set value increase/decrease halting unit 13 for stopping the increase/decrease of the set value when the set value reaches a prescribed value after being increased and decreased by the input units 2 and 3. Further, the in-vehicle equipment control device “S” may further include a set value increase/decrease resuming unit 14 for resuming increasing or decreasing the set value when an input of the input unit 2 or 3 is continued after the increase or decrease of the set value is stopped by the set value increase/decrease halting unit 13.

  • Publication number: 20090248204
    Abstract: The position of a damper is changed over to switch over the cooling mode between an inside air intake mode and an A/C intake mode. In the inside air intake mode, the air inside a passenger compartment of a motor vehicle is taken in and directly blown to a battery by the operation of a battery blower fan. In the A/C intake mode, the air cooled down by an air conditioner (evaporator) is taken in and blown to the battery by the operation of the battery blower fan. When the detected vehicle speed V is not lower than a preset reference speed Vref, the position of the damper is immediately changed over (steps S240 to S260). When the vehicle speed V is lower than the preset reference speed Vref, on the other hand, the operation amount of the battery blower fan is restricted to a preset limit level Qlim, prior to the changeover of the position of the damper (steps S220 to S260).

  • Patent number: 7425085
    Abstract: A vehicle headlight apparatus includes a headlight and an actuator. The actuator horizontally changes a lighting direction of the headlight. The vehicle headlight apparatus drives the actuator such that the actuator horizontally changes the lighting direction of the headlight based on a target swivel angle that is determined based on a travel condition, upon the occurrence of one of the following conditions: (a) the vehicle headlight apparatus detects a dark road section located on a downstream side of a current position of a vehicle, or (b) the headlight is switched on.

  • Patent number: 7281827
    Abstract: A vehicle headlight apparatus includes a headlight and an actuator. The actuator horizontally changes a direction of an optical axis of the headlight. The vehicle headlight apparatus detects a rotational state of at least one predetermined wheel. The vehicle headlight apparatus determines whether a vehicle travels in a forward direction or a non-forward direction based on a detection result. A swivel operation, in which the actuator horizontally changes the direction of the optical axis of the headlight based on a steering operation of the vehicle, is performed when the vehicle headlight apparatus determines that the vehicle travels in the forward direction. The swivel operation is cancelled when the vehicle headlight apparatus determines that the vehicle travels in the non-forward direction.

  • Patent number: 6071542
    Abstract: The present invention provides antibacterial zeolite exhibiting a less discoloring action, obtained by treating the surface of zeolite supporting an antibacterial metal with 0.5 to 20% by weight, based on said zeolite, of a composition comprising (A) 100 parts by weight of a hydrolyzable silane and/or oligomer thereof which comprises 10 to 100% by weight of a hydrolyzable silane and/or oligomer thereof having an aryl group; (B) 1 to 1000 parts by weight of an organopolysiloxane having a basic nitrogen atom; and (C) 0.2 to 250 parts by weight of an acid which is soluble in water and which can form a salt with the aforesaid (B). The present antibacterial zeolite exhibits a remarkably less action of discoloring an organic polymer which contains the antibacterial zeolite when the polymer blend is placed under the influence of heat or the sunshine.
