  • Publication number: 20150199817
    Abstract: A position detection device obtains image coordinate groups representing a coordinate of a target object in each acquired image having first and second acquired image groups. The first acquired image group has acquired images obtained at an image acquiring timing in a reference period. The second acquired image group has acquired images obtained at an image acquiring timing in the reference period, which is delayed from the image acquiring timing of the first acquired image group by an asynchronous time. The device performs a Fourier transformation of each of a first locus and a second locus, and calculates a first frequency waveform based on the first locus and a second frequency waveform based on the second locus. The device calculates a position of the target object based on a relationship in which the frequency waveforms are delayed relative to each other by a phase corresponding to the asynchronous time.

  • Publication number: 20150120085
    Abstract: In a smart system, an onboard system transmits a request signal. A portable device receives the request signal. An LF demodulation portion demodulates the request signal to acquire request data and returns an answer signal based on acquisition of the request data. The onboard system receives the answer signal and performs smart drive based on reception of the answer signal. The onboard system also transmits a specified counter-RA signal. A switching circuit of the portable device outputs the received counter-RA signal to a modulation portion while bypassing the LF demodulation portion. The modulation portion performs RF modulation using the counter-RA signal to acquire a counter-RA modulation signal and transmits the counter-RA modulation signal. When receiving the counter-RA modulation signal, the onboard system determines whether to allow or disallow the smart drive based on delay time of timing to receive the counter-RA modulation signal with reference to timing to transmit the counter-RA signal.

  • Patent number: 9002614
    Abstract: An inter-vehicle distance control device is provided. In this control device, an inter-vehicle distance detecting section detects an inter-vehicle distance between an own vehicle and a preceding vehicle traveling in front of the own vehicle. A laterally adjacent vehicle detecting section detects another vehicle present beside the own vehicle. A cut-in detecting section judges whether or not a cut-in by the other vehicle detected by the laterally adjacent vehicle detecting section is likely to occur, before the other vehicle cuts in between the own vehicle and the preceding vehicle. An inter-vehicle distance adjusting section performs an inter-vehicle distance extension adjustment to increase the inter-vehicle distance when the cut-in detecting section judges that a cut-in is likely to occur. An inter-vehicle distance control section controls the inter-vehicle distance based on information from the inter-vehicle distance adjusting section.

  • Patent number: 8974337
    Abstract: A power transmission apparatus for a vehicle which includes a first, a second, and a third rotor which split power among a motor-generator, an internal combustion engine, and a driven wheel of the vehicle. The apparatus also includes a torque transmission control mechanism which selectively transmits torque between the first rotor and the engine. When the torque transmission control mechanism establishes the transmission of torque between the first rotor and the engine, powers, as produced by the second and third rotors, are opposite in sign to each other. This enables the speed of the first rotor to be set to zero (0) or a very low speed. Therefore, when an initial torque is applied to the engine through the first rotor to start the engine, the mechanical vibration which usually arises from the application of initial torque and is to be exerted on the power transmission apparatus is minimized.
