摘要： A keyless entry system includes a vehicle-side device and a portable device. The vehicle-side device includes a vehicle-side transmission unit connected to a plural transmission antenna and transmitting a request signal, and a vehicle-side reception unit receiving and transmitting an answer signal. The portable device includes a portable device-side control unit that detects the intensity of the signals transmitted from the plural transmission antennas. The vehicle-side control unit or the portable device-side control unit calculates distances between the portable device and the respective transmission antennas based on data of the intensity of the signals transmitted from the plural transmission antennas detected by the portable device-side control unit. When an added value of the distances calculated based on two of the intensity data is smaller than a predetermined threshold value, it is determined that the portable device is located inside the vehicle.

摘要： A mobile device for a vehicle includes a receiving unit that receives transmission signals transmitted from individual transmitting antennas of a vehicle-side device; a control unit that determines distances to the individual transmitting antennas using the signal strengths of the received transmission signals; and a transmitting unit that transmits, to the vehicle-side device using wireless communication, data items indicating the distances. In a time period in which communication is not performed between the mobile device and the vehicle-side device, the signal strength of a received signal is measured, thereby obtaining a measurement value, and the measurement value is stored as a noise element in a memory. When communication between the mobile device and the vehicle-side device is performed, correction for noise is performed on the signal strengths of the transmission signals transmitted from the transmitting antennas, and the distances are determined.

摘要： A keyless entry apparatus is disclosed that is capable of accurately determining whether a portable apparatus is positioned inside or outside an interface between an inner surface and an outer surface of a vehicle even when a region which is affected by crosstalk and/or in which saturation occurs exists outside or inside the vehicle. When an in-vehicle control unit detects that a portable apparatus is positioned in a region which is affected by crosstalk and/or in which saturation occurs, in the vicinities of some of a plurality of transmitting antennas, on the basis of intensity data from some of the plurality of transmitting antennas that is detected by a portable apparatus control unit, the in-vehicle control unit determines whether intensity data from the transmitting antenna that is detected by the portable apparatus is included in a data group composed of a plurality of intensity data that are transmitted from the transmitting antennas and then received by the portable apparatus when the portable apparatus is positioned along the inside of an interface between an inner surface and an outer surface of the vehicle in the region. When it is determined that the intensity data is included in the data group, the in-vehicle control unit determines that the portable apparatus is positioned inside the vehicle. When it is determined that the intensity data is not included in the data group, the in-vehicle control unit determines that the portable apparatus is positioned outside the vehicle.

摘要： A keyless entry device can accurately judge or determine whether a portable device exists inside or outside a vehicle. A vehicle-side controller includes a memory that stores an inside data group having a plurality of intensity information of a request signal transmitted from the plurality of transmitting antennas when the portable device is located along an inside of a vehicle. Also included is an outside data group having a plurality of intensity information of a request signal transmitted from the plurality of transmitting antennas when the portable device is located along an outside of the vehicle. The vehicle-side controller judges an area where the portable device exists from the intensity information of the request signal received from the portable device. The controller instantly judges the inside or the outside of the vehicle, when the portable device exists in an area apart from a boundary. The controller also judges which data group of the inside and outside data groups stored in the memory approximates the intensity information when the portable device exists in the vicinity of the boundary.
