A wiring module includes: a functional sheet disposed between a roof panel forming a roof part of a vehicle and an interior member forming a ceiling shape of a vehicle interior to planarly extend over the roof panel and the interior member; and a transmission member provided on the functional sheet, wherein the functional sheet includes a layer having at least one of a heat insulation function, an acoustic insulation function, and a radio wave shielding function, the transmission member is electrically connected to a vehicle-side apparatus mounted to a side of the vehicle, and the transmission member is formed to extend to a position where the transmission member can perform a power supply to or communication with a roof-side apparatus mounted to the roof part in the functional sheet.

Wiring module

A wiring module includes: a sheet which is a member extending planarly and including an easy-fracture part sectioning the sheet into a plurality of areas and capable of dividing the sheet into the areas; and a transmission member including one of or both a power line supplying an electrical power to at least one apparatus provided in one or more of the plurality of areas and a signal line enabling communication with the apparatus, wherein, in a case where the transmission member is disposed over at least two areas, a part of a middle portion of the transmission member in relation to an end portion connected to the apparatus is fixed to a first area in the two areas, and the transmission member is laid without being fixed to a second area in the two areas.

A power line communication system is provided in which the influence of the impulsive noise unexpectedly generated on a power line which is a communication medium can be reduced according to the characteristics of the impulsive noise by an existing method and power line communication can be realized without a hindrance. A transmitter is constituted by: a modulator for conveying a LIN data signal by a power line; a filter that allows a signal of a predetermined band to pass therethrough; and a sinusoidal wave outputter (sinusoidal wave in the figure). In contrast, the receiver is constituted by the sinusoidal wave outputter, the filter and a demodulator that performs demodulation. To the power line, a limiter that limits the amplitude of the propagating signal to a predetermined amplitude (reception signal amplitude) is connected.

Power line communication system

For voltage values (observed noise sequence) in an electronic power line (communication medium) which are obtained at a predetermined interval, initial values of noise characteristics based on a statistic of the observed noise sequence itself are decided by a moment method (Sto S), the noise characteristics (state transition probabilities and state noise power) for maximization of the likelihood of the observed noise sequence are obtained from the initial values by MAP (Maximum A Posteriori) estimation using a Baum-Welch algorithm (Sto S), a state sequence is estimated from the obtained noise characteristics, and an impulsive noise at each time point is detected.

Noise detection method, noise detection apparatus, simulation method, simulation apparatus, and communication system

A GW device for relaying data sent and received between a plurality of ECUs mounted in a vehicle stores data sent from the respective ECUs in a database and then timely sends the data. The database is stored in a time series in association with time information, and copies of database at a plurality of time points are sent to a central device at predetermined time intervals, or at the time of detection of occurrence of a problem.

Vehicle information recording apparatus, vehicle information communication system and vehicle information communication method

Plural electronic control units (ECUs) are connected to each other by an electric power line that is for supplying electric power. Each ECU sends information with a carrier wave having a first frequency lower than a dip frequency estimated by the physical condition and the circuit structure of electric power line, or having a second frequency lower than the first frequency. Or, the physical condition and the circuit structure of electric power line are determined, on the contrary, to make the dip frequency become higher than the frequency of utilized carrier wave. The frequency utilized for sending information may be selected in accordance with the contents of information.
