Abstract
(EN) An LF transmitter of a vehicle-mounted device transmits a request signal, a first-time measurement signal, and a second-time measurement signal to a portable device. Here, the LF transmitter transmits the second-time measurement signal to a portable device by a transmission strength that is different from the transmission strength of the first-time measurement signal. A UHF receiving unit of the vehicle-mounted device receives from the portable device a response signal which includes information relating to the reception strength of the first-time measurement signal, and information relating to the reception strength of the second-time measurement signal. A determination with respect to the portable device is made based on the relationship between the information relating to the reception strength of the first-time measurement signal and information relating to the reception strength of the second-time measurement signal which are included in the response signal received in the UHF receiving unit, and the relationship between the transmission strength of the first-time measurement signal and the transmission strength of second-time measurement signal which are transmitted from the LF transmitter.
(FR) Un émetteur BF d'un dispositif embarqué transmet un signal de demande, un signal de mesure de premier temps, et un signal de mesure de second temps, à un dispositif portable. Ici, l'émetteur BF transmet le signal de mesure de second temps à un dispositif portable à l'aide d'une puissance de transmission qui est différente de la puissance de transmission du signal de mesure de premier temps. Une unité de réception UHF du dispositif embarqué reçoit à partir du dispositif portable un signal de réponse qui comprend des informations concernant la puissance de réception du signal de mesure de premier temps, et des informations concernant la puissance de réception du signal de mesure de second temps. Une détermination par rapport au dispositif portable est effectuée sur la base de la relation entre les informations concernant la puissance de réception du signal de mesure de premier temps et les informations concernant la puissance de réception du signal de mesure de second temps qui sont comprises dans le signal de réponse reçu dans l'unité de réception UHF, et sur la base de la relation entre la puissance de transmission du signal de mesure de premier temps et la puissance de transmission du signal de mesure de second temps qui sont transmises à partir de l'émetteur BF.
(JA) 車載器のLF送信部は、リクエスト信号、1回目の測定用信号、2回目の測定用信号を携帯機に送信する。ここで、LF送信部は、1回目の測定用信号の送信強度とは異なった送信強度によって2回目の測定用信号を携帯機に送信している。車載器のUHF受信部は、携帯機から、1回目の測定用信号の受信強度に関する情報と、2回目の測定用信号の受信強度に関する情報とが含まれたレスポンス信号を受信する。UHF受信部において受信したレスポンス信号に含まれた1回目の測定用信号の受信強度に関する情報と、2回目の測定用信号の受信強度に関する情報との関係と、LF送信部から送信した1回目の測定用信号の送信強度と、2回目の測定用信号の送信強度との関係とをもとに、携帯機に対する判定がなされる。
