TIRE CONDITION MONITORING APPARATUS WITH KEYLESS ENTRY FUNCTION
First Claim
1. A tire condition monitoring apparatus with a keyless entry function, comprising:
- a keyless entry portable communication device capable of transmitting and receiving high frequency signals;
a plurality of sensor units each being attachable to a wheel of the vehicle, each sensor unit detecting the condition of a tire attached to the wheel and transmitting, as a high frequency signal, a condition data signal that contains data representing the detected tire condition, wherein, in response to the reception of a command signal, which is a high frequency signal, the sensor unit executes operation in accordance with the command content in the command signal;
a plurality of antennas each arrangeable in the vehicle body to correspond to one of the wheels; and
a control unit locatable in the vehicle body and connected to the antennas, the control unit when operated executing a keyless entry function based on transmission and reception of high frequency signals with the portable communication device via at least one of the antennas, and the control unit transmitting the command signal to each of the sensor units via the corresponding antenna and processing the condition data signal received from each of the sensor units via the corresponding antenna.

Abstract
A tire condition monitoring apparatus including a keyless entry portable communication device capable of transmitting and receiving RF signals, sensor units, each of which is attached to a wheel and transmits, as an RF signal, a tire condition data signal, out-of-cabin antennas each corresponding to the wheel, and a control unit mounted on a vehicle body. The control unit executes a keyless entry function based on transmission and reception of RF signals with the portable communication device via the out-of-cabin antennas, and sends a command signal, which is an RF signal, to the sensor units through the out-of-cabin antennas. Upon receiving the command signal, the sensor unit executes an operation that corresponds to the command content of the command signal.
