Abstract

A tire condition monitoring system includes a plurality of tire condition acquisition devices that are installed on pneumatic tires and acquires quantities of tire conditions, and a monitoring device that receives a radio signal from each of the tire condition acquisition devices and performs a predetermined process. The monitoring device sequentially specifies tire labels of the tire condition acquisition devices and requests input of tire positions of the tire condition acquisition devices. The monitoring device generates registration information in which a sensor ID and a tire position are associated based on the input results of the tire position.

Claims

1. A tire condition monitoring system comprising:

a plurality of tire condition acquisition devices that are installed on pneumatic tires and acquire tire condition quantities; and

a monitoring device that receives a radio signal from each of the tire condition acquisition devices and performs a predetermined process;

the monitoring device

storing sensor IDs of the tire acquisition devices, each sensor ID being composed of a multi-digit character string and a simplified tire label corresponding to the sensor ID,

sequentially specifying the sensor IDs of the tire condition acquisition devices and requesting input of a tire position of each of the tire condition acquisition devices by sequentially specifying the tire labels upon requesting input of the tire position, and

generating registration information in which the sensor ID and the tire position are associated based on results of inputting the tire position.

2. The tire condition monitoring system according to claim 1, wherein, upon the tire positions for those of the sensor IDs which are needed being input in response to an input request for tire positions and a confirmation operation being performed,

the monitoring device uses the registration information that is already in existence to generate registration information for the tire positions for others of the sensor IDs.

3. The tire condition monitoring system according to claim 2, wherein the monitoring system comprises a display unit that displays specification of the sensor IDs and input requests for the tire positions, and input results of the tire positions.

4. The tire condition monitoring system according to claim 3, wherein the monitoring system displays to the display unit a plurality of tire position buttons arranged in accordance with an arrangement of tires in a vehicle, and displays input results of the tire positions to the tire position buttons.

5. The tire condition monitoring system according to claim 4, wherein the display unit is a touch panel that can be operated to input the tire positions.

6. The tire condition monitoring system according to claim 3, wherein the display unit is a touch panel that can be operated to input the tire positions.

7. The tire condition monitoring system according to claim 1, wherein the monitoring system comprises a display unit that displays specification of the sensor IDs and input requests for the tire positions, and input results of the tire positions.

8. The tire condition monitoring system according to claim 7, wherein the monitoring system displays to the display unit a plurality of tire position buttons arranged in accordance with an arrangement of tires in a vehicle, and displays input results of the tire positions to the tire position buttons.

9. The tire condition monitoring system according to claim 8, wherein the display unit is a touch panel that can be operated to input the tire positions.

10. The tire condition monitoring system according to claim 7, wherein the display unit is a touch panel that can be operated to input the tire positions.

11. The tire condition monitoring system according to claim 10, wherein the monitoring system displays to the display unit a plurality of tire position buttons arranged in accordance with an arrangement of tires in a vehicle, and senses touch operations of the tire position buttons as input operations of the tire positions.

12. The tire condition monitoring system according to claim 1, wherein the tire condition monitoring system is mounted on a vehicle having six or more wheels.

13. A monitoring device that receives radio signals related to tire condition quantities of a pneumatic tire from a plurality of tire condition acquisition devices and performs predetermined processes,

sensor IDs of the tire condition acquisition devices being stored and sequentially specified, and input of a tire position of each of the tire condition acquisition devices being requested, each sensor ID being composed of a multi-digit character string and a simplified tire label corresponding to the sensor ID, and

registration information being generated in which the sensor ID and the tire position are associated based on results of inputting the tire position by sequentially specifying the tire labels.

14. A monitoring method, comprising:

receiving radio signals related to tire condition quantities of six or more pneumatic tires from tire condition acquisition devices, each of the pneumatic tires being associated with a tire acquisition device,

sequentially identifying a sensor ID of each of the tire condition acquisition devices, each of the sensor IDs comprising a multi-digit character string,

sequentially identifying, in a predetermined order, a tire label for each of the tire acquisition devices, the tire labels being simplified sensor ID indicators comprising fewer characters than the sensor IDs, sequential tire labels comprising sequential letters or numbers,

requesting manual input of a tire position of each of the tire condition acquisition devices, and

generating registration information associating the sensor ID, the tire label, and the tire position for each of the tire acquisition devices based on the input.
