Abstract

A tire theft alarming system includes a vehicular device mounted to a vehicle and a mobile device carried by a user of the vehicle. When a main power supply of the vehicle is in an OFF state, the vehicular device transmits a radio wave including a first alarm based on having a variation in air pressure or acceleration of a tire, which is mounted to the vehicle, detected by a sensor transmitter for detecting and transmitting the air pressure of the tire or the acceleration applied to the tire. The mobile device carries out a warning notification to a user based on having reception of a radio wave including a first alarm transmitted by the vehicular device.

Claims

1. A tire theft alarming system, comprising:

a vehicular device mounted on a vehicle; and

a mobile device carried by a user of the vehicle,

wherein, when a main power supply of the vehicle is in an OFF state, the vehicular device transmits a radio wave including a first alarm based on a variation in air pressure or acceleration of a tire, which is mounted to the vehicle, detected by a sensor transmitter for detecting and transmitting the air pressure of the tires or the acceleration applied to the tires, and

wherein the mobile device carries out a warning notification to the user based on receiving the radio wave including the first alarm transmitted by the vehicular device.

2. The tire theft alarming system according to claim 1,

wherein the vehicular device includes:

a TPMS vehicular device that controls display corresponding to the air pressure of the tires received from the sensor transmitter when the main power supply is in an ON state and stops an operation when the main power supply is in an OFF state;

and a door-control vehicular device that controls door-locking and door-unlocking for the vehicle by at least communicating with the mobile device when the main power supply is in an OFF state,

wherein the sensor transmitter transmits detected air pressure of the tire to the TPMS vehicular device when the main power supply is in an ON state, and transmits the detected air pressure of the tire to the door-control vehicular device when the main power supply is in an OFF state;

and wherein the door-control vehicular device transmits the first alarm via the radio wave to the mobile device based on having a variation in air pressure of the tire received from the sensor transmitter when the main power supply is in an OFF state.

3. The tire theft alarming system according to claim 1,

wherein, after the vehicular device transmits the first alarm by a radio wave, and the vehicular device controls a broadband device, which is mounted to the vehicle, to transmit a second alarm to a predetermined destination outside of a transmission range of the first alarm by outputting a request to the broadband device based on a variation in reception power intensity from the sensor transmitter.

4. The tire theft alarming system according to claim 1,

wherein, after the mobile device carries out the warning notification to the user based on receiving the radio wave transmitted by the mobile device, and the mobile device transmits a call-back to the vehicular device based on receiving a predetermined operation from the user, and

wherein the vehicular device outputs a request to a broadband communication device mounted to the vehicle based on having no reception of the call-back in a period where another predetermined period has elapsed from transmitting the first alarm so that the broadband communication device transmits a second alarm to a predetermined destination outside of a transmission range of the first alarm, and

wherein the vehicular device does not output the request to the broadband communication device based on having reception of the call-back in a period where the predetermined period has elapsed from transmitting the first alarm.

5. The tire theft alarming system according to claim 1,

wherein the vehicular device prohibits transmission of the first alarm in a predetermined waiting period right after receiving an emergency earthquake early notification.
