Patent number: 8731771Abstract: A tire inflation pressure obtaining unit obtains tire inflation pressure. An inflation pressure storing unit stores a tire inflation pressure after start of travel of a vehicle as an after-travel inflation pressure. A pressure reduction determining unit determines reduction in the tire inflation pressure based on the tire inflation pressure obtained. A reference pressure setting unit sets larger one of the after-travel inflation pressure and a predetermined lowest reference pressure as a reference pressure of tire inflation pressure determination when reduction in the tire inflation pressure is determined, and sets the lowest reference pressure as a reference pressure of tire inflation pressure determination when reduction in the tire inflation pressure is not determined. An alarm unit generates an alarm when the tire inflation pressure becomes below an alarm pressure threshold which is determined from the reference pressure.Type: GrantFiled: April 18, 2013Date of Patent: May 20, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hideki Kusunoki, Hideki Ohashi

Patent number: 8466782Abstract: An inflation pressure sensor is mounted in a wheel of a vehicle and determines a tire inflation pressure. A wheel-side communication device transmits a detected tire inflation pressure to a body-side communication device at a predetermined interval. An inflation pressure storing unit stores, as an after-travel inflation pressure, a tire inflation pressure after start of travel of the vehicle. A comparing unit compares the after-travel inflation pressure with a lowest reference pressure. The lowest reference pressure is a tire inflation pressure immediately after start of the vehicle or a predetermined recommended inflation pressure.Type: GrantFiled: April 24, 2009Date of Patent: June 18, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hideki Kusunoki, Hideki Ohashi

Publication number: 20110238238Abstract: If a trigger signal transmitted from another trigger unit in a set range is received after a transmission command switch has been turned on, an annunciation portion is advised of a likelihood of radio interference. In this case, no trigger signal is supplied. If identifier information that has been received corresponds to the identifier information stored in a memory after the transmission of a trigger signal, a count value remains untouched (YES in S55). It is apparent that identifier information was transmitted before from one of wheel-side units that has supplied a trigger signal, and that the trigger signal has not been received by a desired one of the wheel-side units. An operator can supply a trigger signal again through a change in relative position or the like.Type: ApplicationFiled: June 3, 2011Publication date: September 29, 2011Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hideki Kusunoki, Takashi Kida
