Device for monitoring the inflation pressure of the tires of a vehicle
First Claim
1. A device indicating the under-inflation of one of the tires of a vehicle having a chassis and at least one axle with two wheels equipped with tires, based on an analysis of the differences in position of the wheels relative to the chassis, characterized by the fact that the measurement of the differences in position of the wheels of one and the same axle relative to the chassis is effected by means of an element of generally U-shape the central portion of which has a fixed position relative to the chassis of the vehicle and each of the ends of which are connected to one of the wheel holders of the wheels of the axle so that any difference in position between the two wheels relative to the chassis of the vehicle results in a twisting of said element.

Abstract
An arrangement for monitoring the under-inflation of one of the tires of aehicle comprising a chassis and at least one axle having two wheels equipped with tires, based on an analysis of the differences in position of the wheels relative to the chassis, characterized by the fact that the measurement of the differences in position of the wheels on the same axle relative to the chassis is effected by means of an element of generally U-shape, the central portion of which has a fixed position relative to the chassis of the vehicle, and each of the ends of which are connected to one of the wheel holders of the wheels of the axle in such a manner that any difference in position between the two wheels relative to the chassis of the vehicle results in a twisting of said element.

11. A method of detecting the under-inflation of one of the tires of a vehicle comprising a chassis and at least two axles having two wheels equipped with tires, in which:
-
for each axle i, the positions di1 and di2 of each wheel relative to the chassis are measured and δ
i =di1 -di2 is calculated;for each pair of axles i and j, the relationship Δ
ij =Kδ
i -δ
j, in which K is a characteristic function of the axles i and j of the vehicle, is calculated;an alarm is given when Δ
ij satisfies a given relationship. - View Dependent Claims (12, 13)
