  • Publication number: 20150025802
    Abstract: A navigation apparatus includes a control unit for determining whether an approach route to a branch point, which is a route guidance object, and an exit route from the branch point correspond to a learned road link of a learned road data. The control unit provides a normal guidance, instructing a progress direction guidance for the branch point, when none of the approach and exit routes is determined to correspond to a learned road link. Alternatively, the control unit provides a learned road guidance, which is different from the normal guidance, when at least one of the approach route and the exit route is determined to correspond to a learned road link, where the learned road guidance reflects the learned road link in the route guidance.

  • Publication number: 20130304322
    Abstract: A vehicle behavior control apparatus mounted in a vehicle to control steering of the vehicle. A virtual road outline, which is an outline of a drivable road region where the vehicle will travel, is determined on the basis of detection results from a location sensor. The virtual road outline is reconstructed as a sequence of road segments, such as straight road segments, and right- and left-hand curved road segments. When a current road segment where the vehicle is currently present is a right- or left-hand curved road segment, a subsequent road segment where the vehicle will be present subsequently is tentatively set to a straight road segment until the vehicle reaches the subsequent road segment. The steering angle is controlled so that a virtual-road boundary distance is adapted to a proper distance from the vehicle to a boundary of the virtual road outline situated in front of the vehicle.

  • Publication number: 20130220726
    Abstract: A power transducer failure detection device detects a failure on a power transducer, making a power transducer control device stop driving the power transducer. A first switching control device turns off a first power supply relay of a power supply source switching device and turns on a second power supply relay of the power supply source switching device. While the power transducer stops driving, a motor may rotate due to an external force to generate a regenerative voltage. The regenerative voltage is then regenerated in a battery through a route from the power transducer via the second power supply relay being turned on and a parasitic diode of the first power supply relay. This can protect elements such as switching elements and a smoothing capacitor of the power transducer against a regenerative voltage and prevent the elements from being destroyed or reducing the useful life due to overvoltage.

  • Publication number: 20130226214
    Abstract: A hair implanter is equipped with a tube in which a shaft is disposed movable in an axial direction thereof, a tapered hollow needle extending from a tip end of the tube, and slits extending from a tip of the needle in an axial direction thereof to divide a body of the needle into a plurality of needle strips. The needle strips are so shaped that when the shaft is pushed, it contacts inner surfaces of the needle strips, and when the shaft is further advanced in sliding contact with the inner surfaces of the needle strips, the needle strips will elastically bend radially outwardly. Each of the slits extends toward the base end of the tube across a point at which the shaft contacts the inner surfaces of the needle strips. This achieves smooth opening of the tip of the needle with a small degree of force pushing the shaft.

  • Publication number: 20130220256
    Abstract: An engine starter controller for a vehicle equipped with an idle-stop controller includes a user-start circuit, an auto-start circuit, a switch, and a failure detector. The user-start circuit energizes a starter when a driver starts an engine. The auto-start circuit energizes the starter when the idle-stop controller automatically restarts the engine. The switch circuit switches an energization circuit for energizing the starter from the user-start circuit to the auto-start circuit after the user-start circuit starts to energize the starter by causing the auto-start circuit to energize the starter and by putting the user-start circuit into a forced state where the user-start circuit is forced to stop energizing the starter. The failure detector determines whether the auto-start circuit energizes the starter when the energization circuit is switched to the auto-start circuit.

  • Publication number: 20130222128
    Abstract: In a tire pressure detecting apparatus, a receiver stores wheel positions detected by a previous wheel position detection as previous wheel positions. When an ignition switch is turned on and until wheel positions are newly specified by a current wheel position detection, the receiver permits an indicator to indicate tire pressure of each of wheels based on the previous wheel positions to notify a driver of the tire pressure from an earlier timing. The receiver permits the indication of the tire pressure based on the previous wheel positions only when a difference of the tire pressure between the wheels is equal to or less than a threshold. If there is a possibility that tire pressure of one of the wheels is insufficient, the receiver prevents the indicator to indicate the tire pressure until a current wheel position detection finishes.
