Definitions

  • the invention relates to a device for checking vehicle maturity according to the preamble of patent claim 1.
  • the object of the invention is to provide a device for the tire control which responds not only to air pressure differences, but also to other loads on the tires, such as poor wheel balancing, overloading and much more.
  • FIG. 1 shows a block diagram of an embodiment of the system integrated in the vehicle
  • Fig. 3 shows a signal processing and transmission type.
  • Microphones 1 to 4, 101 and 102 are attached to the frame of the vehicle in the vicinity of each wheel and / or structure-borne noise sensors 1 to 4, 104 with the respective preamplifiers 101 to 104a.
  • sensors 111 can measure the temperature at a distance from the tires.
  • the respective speeds 1 to 4 in 105 can also be determined from the transmission or the ABS.
  • a spectrum analyzer 107 either directly or via an electrical or optical interface 106. This leads the sound spectra obtained with or without speed information and / or induced structure-borne sound spectra of each wheel to the evaluation processor 108.
  • a test device 204 can also be installed in the hub 201 with a rim 202 or a further rim 203 of the vehicle in accordance with FIG. 2.
  • this test device supplies the energy supply when driving via a generator 301, which at the same time provides information about the real rotational speed to the microprocessor 304. It can be used directly on the tire or rim, e.g. Sensors for structure-borne noise 302 and temperature 303 can be attached. The information is preselected via the microprocessor 304 and transmitted via an IR diode 305 to one or more receiving diodes 306.
  • This information can be evaluated in the overall system 307 according to FIG. 1.

Abstract

Un dispositif de contrôle de pneus de véhicules, notamment de chambres pneumatiques, lorsque le véhicule est en marche comprend au moins un capteur de mesure par roue à surveiller. Des capteurs soniques (103, 104) et/ou des capteurs thermiques (111) saisissent ensemble des modifications des valeurs correspondantes de mesure au niveau des roues/pneus par comparaison temporelle ou par comparaison de ces valeurs de mesure et les fournissent à un processeur (108) d'évaluation et de traitement de valeurs de mesure qui, lorsque les limites admissibles de déviation sont dépassées, transmet un avertissement à une unité d'affichage (109) ou transmet des impulsions de commande à des mécanismes d'actionnement.
