Method for improving the transmission of data by a wheel unit

A method for managing messages transmitted via radio waves by a wheel unit to an external electronic unit, the method comprising:

• the wheel unit transmits a signal at regular angular intervals of the wheel, and assigns an order number to each of these intervals;
• the external electronic unit detects whether or not this signal is received;
• the external electronic unit sends the wheel unit information representing this detection, or even stores this information;
• the wheel unit or the external electronic unit deduces the angular intervals therefrom, which are referred to as “clear zones”, in which the signal can be transmitted without any alteration or with a slight alteration, and those, which are referred to as “blackspots”, in which the signal risks being altered;
• the wheel unit or the external electronic unit extracts a series of indices of angular intervals of clear zones;
• the wheel unit or the external electronic unit computes a proportion for the arithmetic sequence with the most terms in said sequence, or whose terms correspond to angular intervals allowing the strength of the transmissions of said signal from the wheel unit to the external electronic unit to be optimized;
• the wheel unit transmits messages periodically, with the duration of the period being equal to the travel time of the wheel unit in each of said intervals, multiplied by said proportion.
