Abstract

A ventilation system (1) for vehicles comprises an electric ventilator (2) in turn comprising a fan (4), an electric motor (3) for driving the fan (4) and a microcontroller (6) installed at the motor (3) for controlling the rotation speed of the fan (4), the microcontroller (6) processes one or more vehicle functional parameters according to which it defines the rotation speed of the fan (4).

Claims

1. A ventilation system for vehicles comprising:

at least one electric ventilator comprising a fan, an electric motor for driving the fan and control means installed at the motor for controlling the rotation speed of the fan, wherein the control means comprise processing means for processing at least one vehicle functional parameter used to generate a signal for controlling at least the electric ventilator.

2. The system according to claim 1, wherein the processing means can be associated with the vehicle to process the functional parameter used to define at least the speed of rotation.

3. The system according to claim 1, wherein the control means have at least one input for the functional parameter.

4. The system according to claim 1, wherein the control means have at least one output for the functional parameter.

5. The system according to claim 1, wherein the processing means comprise at least one temperature sensor for detecting the functional parameter.

6. The system according to claim 1, wherein the processing means comprise at least one pressure sensor for detecting the functional parameter.

7. The system according to claim 1, wherein the control means comprise a computerized control unit for controlling the rotation speed of the fan and processing the functional parameter.

8. The system according to claim 1, wherein it comprises at least one second electric ventilator comprising a second respective fan and controlled by the processing means of the first electric ventilator for controlling the rotation speed of the second fan.

9. The system according to claims 8, wherein the control means have at least one input for the functional parameter and the second electric ventilator receives the control signal from the output, the second electric ventilator having a respective input for the control signal.
