Abstract
A tire condition sensing apparatus (14) includes a tire condition sensor (78, 84, 88) for sensing a tire condition and providing a sensor signal indicative thereof. A transmitter (44) transmits a data message having a plurality of data locations for accommodating data. A controller (72) is electrically connected with the tire condition sensor (78, 84, 88) and the transmitter (44). The controller (72) controls the transmitter (44) to transmit tire condition data in selected data locations of the data message based on a parameter associated with the apparatus (14), such as an identification code of the apparatus (14).
Claims30
A tire condition sensing apparatus comprising:
- a tire condition sensor for sensing a tire condition;
- a transmitter for transmitting a data message having a plurality of data locations for accommodating data;
- and
- a controller electrically connected with said tire condition sensor and said transmitter, said controller controlling said transmitter to transmit tire condition data in selected data locations of said data message based on an identification code of said apparatus.
A tire condition sensing system for a vehicle comprising:
- a plurality of tire pressure transmitter modules, each of said plurality of modules having a unique identification code and including:
- a tire condition sensor for sensing a condition of the associated tire;
- a transmitter for, when activated, transmitting a data message having a plurality of data locations for accommodating tire condition data for the associated vehicle tire;
- and
- a controller electrically connected with said tire condition sensor and said transmitter, said controller controlling said transmitter to transmit tire condition data in randomly selected data locations of said data message, the randomly selected data locations being determined based on the unique identification code of said module.
A tire condition sensing apparatus comprising:
- a tire condition sensor for sensing a tire condition;
- a transmitter for transmitting a data message having a plurality of data locations for accommodating data;
- and
- a controller electrically connected with said tire condition sensor and said transmitter, said controller controlling said transmitter to transmit tire condition data in selected data locations of said data message based on a parameter associated with said apparatus.
A method of transmitting a data message from a tire condition module, comprising the steps of:
- sensing a condition of a tire;
- determining random data locations of a data message based on an identification code of the tire condition module;
- and
- transmitting a data message in which tire condition data indicative of the sensed tire condition is provided in the determined random data locations of the data message.
