In a method for providing identification registration of a tire air pressure monitoring apparatus, an external equipment receives transmission data including the sensor identification from transmitters. The external equipment identifies the transmitter that transmitted the transmission data based upon the transmission data and registers the identified transmitter at the receiver.

Sensor ID registration method of tire air pressure monitoring apparatus

Provided is a tire pressure monitoring system capable of preventing mistaken registration of ID due to radio interference. In the system, a tire pressure monitoring apparatus is switched into an ID registration mode while an ID is read out from a bar code or the like and is transmitted to the tire pressure monitoring apparatus. The tire pressure monitoring apparatus registers the received ID in a memory. After the completion of the registration of a necessary number of IDs, the tire pressure monitoring apparatus is switched into a normal mode, before the ID registration operation comes to an end. On the other hand, in the case of tire replacement, through the use of an ID registration tool, an ID is read out from a bar code adhered onto a tire detached and is transmitted to the tire pressure monitoring apparatus. The tire pressure monitoring apparatus removes an ID corresponding to this ID from the memory, and through the use of the ID registration tool, an ID is read out from a bar code adhered onto a tire to be newly mounted and is transmitted to the tire pressure monitoring apparatus to be registered therein.

A transmitter mode switching apparatus switches a transmitter into an ID registration mode, while a receiver mode switching apparatus switches a receiver into an ID transmission mode (step S). Then, a collation ID to be transmitted from the receiver is set based on an ID assigned inherently to the receiver (step S). Subsequently, an ID transmitting apparatus of the receiver transmits the collation ID (step S). An ID receiving apparatus of the transmitter receives the collation ID (step S). An ID registration apparatus of the transmitter stores the received collation ID as a registered ID of the transmitter (step S). After the ID registration is accomplished, the transmitter mode switching apparatus returns the transmitter to an ordinary mode, while the receiver mode switching apparatus returns the receiver to an ordinary mode (step S).

ID registration method, ID collation system incorporated in a vehicle control system, embodied as a pneumatic tire pressure monitoring apparatus associated with pneumatic pressure sensors, and an ID registration tool combined with pneumatic tire pressure monitoring apparatus

A signal receiver for tire air pressure monitoring system determines whether the pressure detection signals from all transmitters have been received during an engine stop state. Upon affirmative determination, the receiver sets a timer, and deactivates the entire or partial function of the receiver. The receiver determines whether the second predetermined period has expired after the setting of the timer. Until the period passes, the receiver retains the deactivated state thereby to save electric power consumption during engine stop state.
