Abstract

A tire pressure monitoring device is mounted on a wheel of a vehicle provided with a pneumatic tire. The device contains a tire pressure sensor and a transmitter which transmits signals wirelessly in transmission intervals, between which in each case there is a first transmission pause. A control device controls the sensor, the transmitter and the first transmission pause thereof. A source provides electrical energy to a rechargeable electric accumulator, in which electrical energy delivered from the source is stored until it is required. The state of charge of the rechargeable electric accumulator is monitored by a monitoring device and one or more of the first transmission causes is/are then ended as soon as enough electrical energy is stored in the rechargeable accumulator to operate the tire pressure monitoring device between two successive first transmission pauses until the conclusion of a predetermined number of transmission processes.
