Transmitter of tire condition monitoring apparatus and tire condition monitoring apparatus
First Claim
1. Transmitters for a tire condition monitoring apparatus, wherein one of the transmitters is provided in a tire located at a left side of a vehicle, and another transmitter is provided in a tire located at a right side of the vehicle, wherein each transmitter includes:
- a condition detection device for detecting condition of the tire; and
an acceleration detection device for detecting a direction of acceleration due to rotation of the associated tire, wherein, based on data representing the direction of acceleration detected by each acceleration detection device, whether the associated transmitter is located in the tire at the left side or in the tire at the right side is identified, and data representing condition of the associated tire detected by the associated condition detection device is wirelessly transmitted.

Abstract
Transmitters of a tire condition monitoring apparatus are provided in the tires at the left side of a vehicle and in the tires at the right side of the vehicle. Each transmitter has a pressure sensor and a temperature sensor for detecting conditions of the associated tire. Each transmitter wirelessly transmits data representing the condition of the associated tire detected by the sensors. Each transmitter has an acceleration detection sensor for detecting a direction of acceleration due to rotation of the associated tire. Based on data representing the direction of acceleration detected by the acceleration detection sensor, whether the transmitter is located in the tire at the left side or in the tire at the right side is identified.

6. A tire condition monitoring apparatus for monitoring condition of a tire located at a left side of a vehicle and a tire located at a right side of the vehicle, wherein the apparatus includes transmitters each located in one of the tires, wherein each transmitter includes:
-
a condition detection device for detecting condition of the associated tire;
an acceleration detection device for detecting a direction of acceleration due to rotation of the associated tire, wherein, based on data representing the direction of acceleration detected by each acceleration detection device, whether the associated transmitter is located in the tire at the left side or in the tire at the right side is identified, and data representing condition of the associated tire detected by the associated condition detection device is wirelessly transmitted, the tire condition monitoring apparatus further comprising;
trigger signal transmission devices, wherein the trigger signal transmission devices are located in the vicinity of the tires to correspond to the transmitters, wherein each transmitter includes a trigger signal detection device, wherein, when a trigger signal is detected by the trigger signal detection devices, the transmitters wirelessly transmit data representing the condition of the tires at different timings based on whether each transmitter is located in the tire at the left side or in the tire at the right side;
a reception antenna for receiving data wirelessly transmitted by the transmitters; and
a receiver for processing data received by the reception antenna. - View Dependent Claims (7, 8, 9, 10, 11)
