RF transmission method and apparatus in a tire pressure monitoring system

摘要

In some aspects, a plurality of frames to be transmitted is assembled. The averaging factor is determined for each frame. Each frame is transmitted with the averaging power determined for each frame and not with the worst case averaging power from the plurality of frames.

主权项

1. A method of increasing transmission performance between a tire pressure monitoring sensor and a receiver in a vehicle, the method comprising:
receiving a plurality of frames to be transmitted, each of the plurality of frames being separated by a first inter frame timing distance; determining an averaging factor for each of the plurality of frames, and a worst case averaging factor; determining a second inter frame timing distance that separates each of the plurality of frames, the second inter frame timing distance being less than the first inter frame timing distance; assembling the frames into a transmission burst and separating these frames with the second inter frame timing distance; inserting an additional frame into the transmission burst; transmitting each of the frames of the transmission burst with the worst case averaging factor.
