1. A vehicular system comprising:
- a pressure detector for detecting a tire pressure of tires of a vehicle;
a communication terminal including a terminal transmitter and a terminal receiver; and
a handset including a receiver unit and a transmission unit, whereinthe combination terminal and the handset are carried by the user;
the terminal transmitter of the communication terminal transmits a forced-operation signal to forcefully operate the pressure detector to the handset,the transmission unit of the handset transmits the forced-operation signal received from the communication terminal by the receiver unit to the pressure detector via an entry system of the vehicle, andthe terminal receiver receives tire pressure information from the pressure detector.

Abstract
An in-vehicle apparatus allows the user to check and adjust tire pressure whenever he/she thinks of doing it, by transmitting, from a portable unit that is carried by the user, a start request signal through UHF band electric wave to forcefully operate sensor units for detecting the tire pressure in each of the tires of the automobile, by collecting the tire pressure information to a control unit of the in-vehicle apparatus, and by displaying the tire pressure on a display unit of the portable unit when the tire pressure information is transmitted from a Bluetooth unit of the in-vehicle apparatus to a Bluetooth unit of the portable unit.

10. A vehicular system comprising:
-
a pressure detector for detecting a tire pressure of tires of a vehicle; and a handset that is carried by a user, wherein the handset includes; a transmission unit for wirelessly transmitting a forced-operation signal to forcefully operate the pressure detector; and a receiver unit for wirelessly receiving tire pressure information detected by the pressure detector;
whereinthe pressure detector includes; a tire sensor disposed in each tire for detecting air pressure in each tire; a wireless communication unit for transmitting the tire pressure information detected by the tire sensor in each tire; a collection unit for collecting the tire pressure information by receiving the tire pressure information transmitted by the wireless communication unit; a detector transmitter for transmitting the tire pressure information collected by the collection unit; and a detection signal transmitter for transmitting to each of the tire sensors a detection instruction signal for pressure detection when the forced-operation signal is transmitted from the transmission unit of the handset, the tire pressure information is collected by the collection unit from each tire in response to the detection instruction signal transmitted from the detection signal transmitter, and the collected tire pressure information is transmitted from the detector transmitter;
wherein the vehicle system further comprises;a first determination unit for determining whether any tire sensor transmits a pressure change exceeding a threshold based on the tire pressure information collected by the collection unit, wherein, when at least one of the tire sensor is determined by the first determination unit to transmit the pressure change exceeding the threshold, the detection instruction signal is transmitted only to the tire sensor that is determined to transmit the pressure change exceeding the threshold, in order to collect the tire pressure information from the tire sensor. - View Dependent Claims (11)
