First Claim
1. A system for warning against a tire air pressure comprising:
- air pressure measuring means for measuring a tire air pressure of a tire of a vehicle;
air pressure judging means for judging, on the basis of the tire air pressure measured by said air pressure measuring means, whether or not the tire air pressure is proper;
warning issuing means for issuing, if a result of the judgment by said air pressure judging means is negative, a warning;
driver on-board judging means for judging whether or not a driver is on board the vehicle; and
driver detecting means for detecting whether or not the driver is in the proximity to the vehicle,if the result of the judgment by said air pressure judging means is negative, a result of the judgment by said driver on-board judging means is negative and a result of the detection by said driver detecting means is positive, said warning issuing means issues the warning outside the vehicle.

11. A method for warning against a tire air pressure comprising the steps of:
-
(a) measuring a tire air pressure of a tire of a vehicle; (b) judging, on the basis of the tire air pressure measured in said step (a) of measuring, whether or not the tire air pressure is proper; (c) judging whether or not a driver is on board the vehicle; (d) detecting whether or not the driver is in the proximity to the vehicle; and (e) if a result of said step (b) of judging is negative, issuing a warning in accordance with results of said step (c) of judging and said step (d) of detecting, wherein, if the result of said step (b) of judging is negative, the result of said step (c) of judging is negative and the result of said step (d) of detecting is positive, a warning is issued outside the vehicle in said step (e) of issuing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
