Method for determining a measurement signal according to the electrical signal at the output of a sensor

A method for determining, by a processor of a vehicle, a measurement signal, based on an electrical signal, at an output of a tire sensor arranged on a wheel of the vehicle, the tire sensor of the vehicle comprising a transducer capable of generating the electrical signal based on radial acceleration measured by the tire sensor and comprising a conversion of the electrical signal into a measurement signal of the radial acceleration of the tire sensor of the vehicle and at least one physical parameter to be measured other than the measured radial acceleration that can affect an amplitude of the generated electrical signal, the method comprising:

• at a first instant, determining, by the processor of the vehicle, respective measurement signals for at least two pairs of values by applying the tire sensor conversion of respective electrical signals into the respective measurement signals of the radial acceleration to at least two predetermined electrical signal values, each pair of values comprising the respective electrical signals and the respective measurement signals, and
• at a second instant, determining, by the processor of the vehicle, a mathematical function that is substantially equivalent to the tire sensor conversion, the mathematical function allowing the respective measurement signals to be obtained based on the respective electrical signals generated by the tire sensor of the vehicle is determined based on the pairs of values comprising the respective electrical signals and the respective measurement signals, and then
• at a third instant, determining, by the processor of the vehicle, at least two measurement signals of the radial acceleration by applying the mathematical function to at least two electrical signals of the tire sensor of the vehicle without using the tire sensor conversion,
• wherein the determination of the at least two measurement signals via the mathematical function at the third instant are separated by a length of time shorter than a time taken to convert the at least two electrical signals into the at least two measurement signals of the radial acceleration by the tire sensor conversion in the first instant, and
• executing, by the processor of the vehicle, a vehicle application that utilizes the radial acceleration of the at least two measurement signals determined at the second instance.
