Abstract
The present invention relates to a method for detecting overheating of an electrical heating device comprising a plurality of resistive elements configured to be supplied electrically using a control signal by pulse width modulation according to a setpoint, comprising the following steps: —detecting the setpoint, —detecting the duty cycle (PWM_system; PWM_subsystem), —defining a threshold value for detecting the duty cycle according to the setpoint, or a value of at least one parameter for monitoring an incidence of overheating, —comparing the detected duty cycle value with the detection threshold value, and —detecting an incidence of overheating when the detected duty cycle value reaches the detection threshold value. The invention also relates to a corresponding control unit.
