  • Patent number: 7477978
    Abstract: A device adapted to automatically control the effective output of a vehicle control system/component that, for example, automatically applies braking and/or steering control, in response to tire contact with a rumble strip. The device includes a processor configured to receive a first signal indicative of contact of a vehicle tire with a rumble strip. The processor also includes logic to determine that at least one vehicle tire is in contact with a rumble strip based at least on the first signal. If the processor has received the first signal and has determined that the at least one vehicle tire is in contact with the rumble strip, the processor then issues a command to control the effective output of at least one of a vehicle control component or a vehicle control system. For example, an automatically applied braking force may be reduced to ½ its normal applied force.

  • Publication number: 20090007887
    Abstract: A fuel injection valve is provided with a main body and a valve member. The main body has a fuel passage and a fuel injection opening formed at the downstream-end of the fuel passage. The valve member is provided in the fuel passage. The valve member is configured to move between a first position in which the valve member closes the fuel injection opening and a second position in which the valve member opens the fuel injection opening. A hardened layer is formed on abutment surfaces of the valve member and the main body that abut with each other. The hardness of this hardened layer is lower in its surface side than in its bottom side. According to this structure, the stress generated inside the hardened layer is suppressed, and breakage and detachment of the hardened layer are prevented.

  • Publication number: 20070228193
    Abstract: The invention provides an effective technique for improving the sealing performance and durability of a fluid control valve, particularly a fuel injector. The fuel injector 10 has a ball valve 32 and a valve seat body 41. A fuel jet opening 41c formed in the valve seat body 41 is closed when the ball valve 32 contacts a sealing surface 41b of the valve seat body 41, while being opened when the ball valve 31 separates from the sealing surface 41b of the valve seat body 41. A stainless steel base material and a Sn plated film softer than the base material form a smooth surface 42 on the sealing surface 41b of the valve seat body 41.

  • Publication number: 20070225914
    Abstract: An a lane departure prevention system is described having a position detector for detecting positional information of a vehicle with respect to a lane of travel. A determining unit is included for comparing the positional information with a first threshold value indicating a predetermined positional relation with respect to the lane of travel, and for determining a tendency of the vehicle to depart from the lane of travel on the basis of a comparison result. At least one control is selectively adjusted when the determining unit determines that the vehicle is tending to depart from the lane of travel. The at least one control is selectively delayed or selectively reduced as a result of a proximate predetermined physical object.
