Method for in-vehicle communications during use of the vehicle, in which a first, data-processing component is arranged on the vehicle, at least one second component is arranged on a non-rotating part of the vehicle, each second component being a sensor arranged to measure a property of the vehicle or a component thereof or an actuator arranged to control a system, subsystem or other component of the vehicle, and the first and second components wirelessly communicate with one another. When the second component is a sensor, it wirelessly transmits data about the measured property and the first component receives the data wirelessly from the second component and processes the received data. When the first component is an actuator, it processes data relating to control of the second component and generates and wirelessly transmits signals to the second component to control the system, subsystem or other component of the vehicle.

The invention claimed is: 1. A method for obtaining information about or relating to a vehicle or a vehicular component located within the vehicle, comprising: arranging at least one sensor in the vehicle or in connection with the component to generate information about or relating to the vehicle or component; enabling the at least one sensor to wirelessly transmit the generated information; arranging an interrogator on the vehicle apart from the at least one sensor; and directing a transmission from the interrogator to cause the at least one sensor to transmit the generated information to the interrogator. 2. The method of claim 1, further comprising providing power to the at least one sensor wirelessly via the interrogator. 3. The method of claim 1, wherein the component is a seat in the vehicle and the at least one sensor includes a pressure sensor arranged in connection with the seat, the information being generated by the pressure sensor being information about pressure applied by an occupant to a bottom cushion of the seat. 4. The method of claim 1, wherein the at least one sensor is a radio frequency identification type sensor or a surface acoustic wave type sensor. 5. The method of claim 1, further comprising directing the at least one sensor to transmit an identification signal associated therewith in conjunction with the transmission of the generated information. 6. The method of claim 1, further comprising: arranging at least one additional sensor in conjunction with at least one other component to generate information about or relating to that component; enabling the at least one additional sensor to wirelessly transmit the generated information; directing a transmission from the interrogator to cause the at least one additional sensor to transmit the generated information to the interrogator; and distinguishing between the information being transmitted by the sensors using time, code, space or frequency multiplexing. 7. The method of claim 1, wherein the at least one sensor is arranged in connection with a non-rotating component of the vehicle. 8. The method of claim 1, further comprising: directing transmissions from the interrogator at periodic intervals; and varying the periodic intervals based on at least one of the type of sensor, the component and the information generated by the sensor. 9. The method of claim 1, wherein information about or relating to a component is obtained, further comprising determining the location of the component based on analysis of the transmitted information. 10. The method of claim 1, wherein the component is a seat, further comprising: controlling an occupant restraint system which is designed to protect an occupant of the seat in the event of a crash involving the vehicle based on the generated information. 11. The method of claim 10, further comprising: directing transmissions from the interrogator at periodic intervals; and varying the periodic intervals based on occupancy of the seat. 12. A system for obtaining information about or relating to a vehicle or a vehicular component in a vehicle, comprising: at least one sensor arranged in the vehicle or in connection with the component to generate information about or relating to the vehicle or component, each of said at least one sensor including means for enabling wireless transmission of the generated information; and an interrogator arranged on the vehicle apart from said at least one sensor, said interrogator being arranged to transmit a signal to cause said at least one sensor to transmit the generated information to said interrogator. 13. The system of claim 12, wherein said interrogator is arranged to provide power to said at least one sensor wirelessly. 14. The system of claim 12, wherein the component is a seat in the vehicle and said at least one sensor includes a pressure sensor arranged in connection with the seat, the information being generated by said pressure sensor being information about pressure applied by an occupant to a bottom cushion of the seat. 15. The system of claim 12, wherein said at least one sensor is a radio frequency identification type sensor or a surface acoustic wave type sensor. 16. The system of claim 12, wherein said at least one sensor is arranged to transmit an identification signal in conjunction with the transmission of the generated information. 17. The system of claim 12, further comprising: at least one additional sensor arranged in conjunction with at least one other component to generate information about or relating to that component, said at least one additional sensor including means for enabling wireless transmission of the generated information; said interrogator being arranged to direct a transmission to cause said at least one additional sensor to transmit the generated information to said interrogator, the information being transmitted by said sensors being distinguished using time, code, space or frequency multiplexing. 18. The system of claim 12, wherein said at least one sensor is at least one of a pressure and temperature sensor and the component is a tire.
