Title:
TIRE CONDITION MONITORING DEVICE
Document Type and Number:
Japanese Patent JP2016203834
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tire condition monitoring device in which a receiver can receive a signal transmitted from a transmitter, with a simple circuit configuration even when a transmission time of the transmitter is shorter than a reception interval of the receiver, in a case where the transmitter installed to a tire and the receiver installed to a vehicle body operate intermittently, respectively.SOLUTION: Every time a period corresponding to one period Tr1 of intermittent reception processing on a vehicle side device passes, a transmission interval Tt1 of a notification signal is controlled so that a transmission time Tp1 of preamble of the notification signal is shifted to a direction of relatively delaying with respect to an execution time Tw1 of the reception processing. When the transmission time Tp1 of the preamble in the relative shift step, passes through a range of the execution time Tw1 of the reception processing, whole body of the transmission time Tp1 of the preamble is included in the range of the execution time Tw1 of the reception processing, by controlling the transmission interval Tt1 of the notification signal.SELECTED DRAWING: Figure 5
