Abstract

A system for monitoring the vehicle tire inflation pressure has a device for detecting the vertical acceleration of the tire or of a vehicle component connected therewith and the longitudinal speed of the vehicle, as well as having an analyzing unit which determines the tire inflation pressure from the measured vertical acceleration data and the measured vehicle longitudinal speed data. The analyzing unit contains a trainable estimating unit, particularly a neuronal network, which is trained by predeterminable training example data with different tire inflation pressure values and vehicle longitudinal speed values. In the trained condition, the estimating unit determines the tire inflation pressure at least as a function of the measured vertical acceleration and vehicle longitudinal speed data fed directly or preprocessed on an input side thereof. The system provides continuous tire inflation pressure monitoring in the case of road vehicles.
