The invention relates to a device for controlling a complementary electric radiator (R) installed in a ventilation system used in the automotive sector, said device including at least two electronic modules each including a computer, a control module (1) capable of sending operating commands to the radiator and a management module (2), which is implemented within the electric radiator (R) in order to manage the operation thereof on the basis of commands received from the control module (1). According to the invention, the control module (1) includes a unit for generating and transmitting a PWM signal representative of the operating commands being sent to the radiator (R) over a communication wire (3) connected to the management module (2) and a unit for reading the signal travelling over the communication wire (3); the management module (2) includes a unit for altering the PWM signal travelling over the communication wire on the basis of detected events in the operation of the radiator (R).
A device for controlling a complementary electric radiator installed in a ventilation system used in the automobile sector, the device comprising at least two electronic modules each including a computer, wherein a first electronic module is a control module suitable for sending operating commands to the radiator and a second electronic module is a management module which is disposed within the radiator and manages operation of the radiator according to the commands received from the control module, wherein the control module comprises a unit for generating and transmitting a PWM signal representative of the operating commands to be sent to the radiator over a single communication wire linked to the management module and a unit for reading the signal circulating on the single communication wire, and the management module comprises a unit for altering the PWM signal circulating on the single communication wire according to diagnostic feedback from the operation of the radiator, and the PWM signal is transmitted back and forth between the control module and the management module across the single communication wire.
A method for controlling a complementary electric radiator installed in a ventilation system used in the automobile sector, the method comprising a step of sending, via a control module, operating commands to the radiator and a step of managing the operation of the radiator, via a management module disposed within this radiator, according to the commands received from the control module, wherein the control method also comprises:
