Title: Tire air pressure drop alarm device
Inventor: BOESCH MATHEW ALAN
IPC: B60C23/02
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a system for detecting tire air pressure drop directly, positively and safely from displacement measured on the effective rolling radii of four wheels of an automobile and outputting a correct alarm. SOLUTION: Automobile driving conditions of excessive speed or very low speed, braking, rotation, and the like are determined from the output of angular displacement sensors 22, 24, 26, 28 so as not to make a wrong decision on a change in each effective rolling radius. What is judged to be acceptable out of data from the sensors is integrated as the displacement value to each wheel. When the displacement value exceeds the specified value, difference detected in the integrated displacement value on a front wheel pair 12, 14 and a rear wheel pair 16, 18 is compared. In case of the difference between the wheel pairs being excessive compared to the specified base line metric value, tire pressure drop is detected. As the detected state is integrated, the actual presence of the state becomes reliable. As a result, an alarm is outputted to an automobile driver.
