Title (EN) SYSTEM FOR DETERMINING CORRECTNESS OF WIRELESS COMMUNICATION
(FR) SYSTÈME POUR DÉTERMINER L'EXACTITUDE D'UNE COMMUNICATION SANS FIL
(JA) 無線通信正否判定システム
Abstract:
(EN) A system in which a vehicle (1) and an electronic key (2) communicate by UHF radio waves (24, 28) of the same frequency band, wherein the electronic key (2) calculates the received signal strength of the radio waves (24) from the vehicle (1) and transmits received signal strength information (30) indicating the received signal strength to the vehicle (1). The vehicle (1) calculates the difference between the received signal strength information (30) received from the electronic key (2) and the received signal strength of the radio waves (28) in which the received signal strength information (30) is carried, and confirms whether or not this difference is within a reference range, thereby determining the communication correctness of smart communication.
(FR) L'invention concerne un système dans lequel un véhicule (1) et une clé électronique (2) communiquent par ondes radio UHF (24, 28) de la même bande de fréquences. La clé électronique (2) calcule l'intensité du signal reçu des ondes radio (24) du véhicule (1) et transmet des informations d'intensité de signal reçu (30) indiquant l'intensité de signal reçu au véhicule (1). Le véhicule (1) calcule la différence entre les informations d'intensité de signal reçu (30) reçues de la part de la clé électronique (2) et l'intensité de signal reçu des ondes radio (28) dans lesquelles sont transportées les informations d'intensité de signal reçu (30), et vérifie si cette différence se situe ou non dans une plage de référence, déterminant ainsi l'exactitude d'une communication intelligente.
(JA) 車両(1)と電子キー(2)とが同一周波数帯のUHF電波(24、28)で通信するシステムにおいて、電子キー(2)が車両(1)からの電波(24)の受信信号強度を算出し、その受信信号強度を示す受信信号強度情報(30)を車両(1)に送信する。車両(1)は、電子キー(2)から受信した受信信号強度情報(30)とその受信信号強度情報(30)が乗った電波(28)の受信信号強度との差分を算出して、この差分が基準範囲にあるか否かを確認することにより、スマート通信の通信正否を判定する。
