Monitoring and/or control device for the functioning ability of a tyre using electrical conduction for the transmission of an electrical signal between a wheel and the vehicle

摘要

The proposed circuit is to be mounted on a wheel of a vehicle, and to allow the transmission of an electrical signal by the bearings. For this purpose, the observation parameters on the wheel (pressure, temperature of the tire) is reduced to the observation of 3 resistors of sufficiently different values: the resistance of a semiconductor T₂ in the conducting state, a resistor R₀ upper two orders of magnitude to the previous and the internal resistance at least one semiconductor or T₂ T₁ in the off state. It is also proposed to Integer the pressure switch required with a conventional valve. Alternatively, it is possible to control an electric element mounted on the wheel.
