Abstract
The invention concerns a system for determining inflating pressures of tires mounted on a motor vehicle wheels, this system comprising means (12, 13) for acquiring vertical accelerations of a front wheel and of a rear wheel of the vehicle and means (34) for estimating coefficients of stiffness of the tires of said wheels based on the acquired accelerations on another of the acquired accelerations, and in that the estimation means (34) are adapted to estimate these coefficients of stiffness based on the thus temporally reset accelerations.

System for determining the inflating pressures of tires mounted on motor vehicle wheels, the system including:
- means for acquiring vertical accelerations of a front wheel and of a rear wheel of the vehicle;
- and
- means for estimating coefficients of stiffness of the tires of these wheels as a function of the acquired accelerations,
- means for temporally resetting one of the acquired accelerations on the other of the acquired accelerations, the estimation means being adapted to estimate said coefficients of stiffness as a function of the thus temporally reset accelerations.
