VEHICLE STATE NOTIFYING SYSTEM, ITS CONSTITUENT DEVICE, AND NOTIFYING METHOD
First Claim
1. A vehicle state notifying device, comprising:
- a radio communication means for performing bidirectional intermittent communication with a portable terminal device by using weak power which is not restricted by a law;
a transmission request receiving means for receiving, from the portable terminal device, a transmission request to send information indicating a current state of a vehicle to be monitored, through the radio communication means;
a vehicle state detecting means for obtaining a detection result detected by a predetermined sensor, regarding the state of the vehicle corresponding to the transmission request received by the transmission request receiving means; and
a control means for controlling an operation of the radio communication means such that the radio communication means intermittently sends notification data having a predetermined data structure, indicating the detection result obtained by the vehicle state detecting means, at an interval at which the portable terminal device can receive the notification data.

Abstract
A vehicle state notifying system for notifying the user of a vehicle state through a simple configuration at a low cost is proved. The notifying system includes a slave device which the user carries and a master device radio-communicatable with the slave device bidirectionally. Upon reception of send request data from the slave device, the master device generates notification data indicating the state of an automobile from the detection result of the state of the automobile detected by various sensors and sends the notification data to the slave device through weak radio. The master device synchronizes the transmission timing of the notification data with the reception operation interval of the slave device.

7. A portable terminal device, comprising:
-
a radio communication means for performing bidirectional intermittent communication with a notifying device which notifies of a vehicle state in response to a request, by using weak power which is not restricted by a law; a transmission request data generating means for generating transmission request data to request, through the radio communication means, the notifying device to send notification data indicating a current state of a vehicle to be monitored; and a control means for controlling an operation of the radio communication means such that the radio communication means intermittently sends the transmission request data generated by the transmission request data generating means to the notifying device at an interval assigned in advance to the portable terminal device, and also receives the notification data sent to the portable terminal device. - View Dependent Claims (8, 9, 10)

12. A vehicle state notifying method, which is executed by a notifying device and a portable terminal device each having a radio communication means for performing bidirectional intermittent communication by using weak power which is not restricted by a law, the method comprising the steps of:
-
intermittently sending, by the portable terminal device, transmission request data, to the notifying device, to request for transmission of notification data indicating a current state of a vehicle to be monitored, at an interval assigned to the portable terminal device; establishing, by the notifying device, synchronization of intermittent communication with the portable terminal device upon reception of the transmission request data, and intermittently sending notification data having a predetermined data structure indicating a detection result regarding the vehicle state obtained through detection of a predetermined sensor, at an interval at which the portable terminal device, which has established synchronization, can receive the notification data; and notifying, by the portable terminal device, after receiving the notification data, the user of the vehicle state identified by the notification data, by visually expressing the vehicle state.
