COMMUNICATION SYSTEM FOR VEHICLE, ON-VEHICLE APPARATUS AND PORTABLE MACHINE
To provide a communication system for vehicle which facilitates establishment of communication between a portable machine and an on-vehicle apparatus and has low consumption power.SOLUTION: A communication system for vehicle 1 performs wireless communication between a portable machine 20 and an on-vehicle apparatus 10 mounted on a vehicle 2 and comprises tire pneumatic pressure sensors 30 which include sensor parts attached to a plurality of tires 3 of the vehicle 2, respectively, and detect the pneumatic pressure of the tires 3 and a tire radio part which wirelessly transmits a signal showing the pneumatic pressure detected by the sensor parts. The tire radio part is capable of wirelessly transmitting and receiving a signal between the portable machine 20 and the on-vehicle apparatus 10 and makes it possible to switch between direct communication of the portable machine 20 with the on-vehicle apparatus 10 and relay communication of the portable machine 20 with the on-vehicle apparatus 10 via the tire pneumatic pressure sensors 30.SELECTED DRAWING: Figure 1
【課題】携帯機と車載器との通信が成立しやすく、かつ、消費電力が少ない車両用通信システムを提供する。【解決手段】携帯機２０と、車両２に搭載された車載器１０との間で無線通信を行う車両用通信システム１であって、車両２が備える複数のタイヤ３にそれぞれ取り付けられ、タイヤ３の空気圧を検出するセンサ部と、センサ部が検出した空気圧を示す信号を無線送信するタイヤ無線部とを有するタイヤ空気圧センサ３０を備え、タイヤ無線部は、携帯機２０および車載器１０との間で無線による信号の送受信が可能であり、携帯機２０と車載器と１０の直接通信と、タイヤ空気圧センサ３０を介した携帯機２０と車載器１０との中継通信とが切り換え可能になっている。【選択図】図１
