Data processing method and assembly of a seat and a controller

A method for processing capacitance values generated by capacitive sensors with interdigitated electrodes supported by a seat of a vehicle, in particular a motor vehicle;

• the seat being equipped with a heating system, the method being implemented by a controller capable of receiving capacitance values measured by the capacitance sensors with interdigitated electrodes at regular time intervals during the entire duration of the method;
• the controller being capable of receiving a warning signal indicating an operating or non-operating state of the heating system;
• the method comprising the following steps:
• detecting the presence of an occupant on the seat from the capacitance values received;
• receiving a warning signal indicating an operating state of the heating system,
• upon receipt of the warning signal, implementing an initial phase during which an adaptive compensation is applied to each capacitance value received, the adaptive compensation having a value which increases over time during the initial phase;
• implementing a continuation phase after a defined time with respect to the receipt of the warning signal, a continuation compensation being applied to each capacitance value received during the continuation phase;
• the continuation compensation having a constant value during the continuation phase;
• the continuation phase being implemented as long as the heating system is in an operating state and as long as the occupant is seated on the seat;
• wherein the initial phase comprises at least a first period and a second period subsequent to the first period, the increase in the adaptive compensation during of the first period being greater than the increase in adaptive compensation during the second period;
• and wherein applying adaptive compensation to each received capacitance value comprises an addition of the adaptive compensation;
• the second period comprising several sub-periods subsequent to each other;
• the adaptive compensation value added to the capacitance values during a following sub-period being increased by a second defined quantity with respect to the adaptive compensation value added to the capacitance values measured during a current sub-period.
