Apparatus and method for alarming decrease in tire air-pressure
First Claim
1. An apparatus for alarming a decrease in tire air-pressure which alarms the decrease in inner pressure of the tire by using a judged value calculated based on rotational information obtained from tires fitted to a four-wheeled vehicle, comprising:
- traveling determining means for determining whether the vehicle should be stopped at once or the vehicle can still travel to some extent when the decrease in tire air-pressure is judged;
vehicle position detecting means for detecting a vehicle traveling position at the time of judgment of the decrease in tire air-pressure;
collating means for collating the detected vehicle traveling position with positional information on a blowout repairing facility, which has been input previously;
facility calling means for calling a nearest blowout repairing facility being open based on the collation by the collating means; and
display means for displaying a route from the vehicle traveling position to the called facility, wherein the vehicle position detecting means, the collating means, the facility calling means and the display means are started to be operated in the case where the traveling determining means determines that the vehicle can still travel to some extent.

Abstract
An apparatus for alarming a decrease in tire air-pressure by using a judged value calculated based on rotational information obtained from tires fitted to a four-wheeled vehicle. The apparatus comprises: traveling determining means for determining whether the vehicle should be stopped at once or the vehicle can still travel to some extent; vehicle position detecting means; collating means for collating the detected vehicle traveling position with positional information on a blowout repairing facility; facility calling means for calling a nearest blowout repairing facility; and display means for displaying a route from the vehicle traveling position to the called facility. The apparatus according to the present invention can teach the route to the blowout repairing facility after giving the alarm of the decrease in tire pressure, thus achieving the repairing of blown-out tire after the safe traveling.
