VEHICLE THEFT ALERT SYSTEM
First Claim
1. A vehicle theft alert system comprising:
- a lock state determination portion determining whether doors of a vehicle are in locked states, and the doors entering the locked states after a turn-off of a main power of the vehicle; and
a transmission control portion switching from a normal mode to an alarm mode when the lock state determination portion determines that the doors are in the locked states, whereinwhen a change amount of an air pressure of a tire of the vehicle is greater than a first pressure range in the alarm mode or when a change amount of an acceleration applied to the tire is greater than a predetermined acceleration range in the alarm mode, the transmission control portion controls a mobile communication apparatus equipped to the vehicle to transmit an alarm information to an external apparatus located outside the vehicle,the transmission control portion includes;
a first transmission control portion that controls the mobile communication apparatus to transmit the alarm information to the external apparatus when the air pressure of the tire changes relative to a first pressure reference value by an amount greater than the first pressure range in the alarm mode; and
a second transmission control portion that controls the mobile communication apparatus to transmit, to the external apparatus, a slow leak information indicating that a decrease of the air pressure is caused by a slow leak when the air pressure of the tire becomes equal to or hiqher than a theft determination threshold and lower than a slow leak threshold in the alarm mode, and the theft determination threshold is obtained by subtracting the first pressure range from the first pressure reference value and the slow leak threshold is set to be higher than the theft determination threshold.

Abstract
A vehicle theft alert system includes a lock state determination portion and a transmission control portion. The lock state determination portion determines whether doors of a vehicle have entered locked states after main power of the vehicle is turned off. The transmission control portion switches from normal mode to alarm mode when the lock state determination portion determines that the doors are locked. When a change amount of an air pressure of a tire of the vehicle is greater than a first pressure range in the alarm mode, or when a change amount of an acceleration applied to the tire is greater than a predetermined acceleration range in the alarm mode, the transmission control portion controls a mobile communication apparatus equipped to the vehicle to transmit an alarm information to an external apparatus located outside the vehicle.
