Preferably, the seat cushion fan 5 is mounted below the seat cushion and the seat back fan 6 is mounted behind the back.
The invention also provides a control method of the seat automatic ventilation system, which comprises the following steps: the controller 1 receives the detection signal from the detection device and carries out processing and judgment, if the seat is not used, the controller 1 does not receive other signals, and if the seat is used, the controller 1 receives the signal from the switch 3 and carries out processing and judgment;
when the switch 3 is in the Auto gear, the controller 1 receives temperature signals from the first temperature sensor 4 and the second temperature sensor 7 and judges a seat cushion temperature value and a backrest temperature value; if the seat cushion temperature value is higher than a first threshold value C, the control module controls the seat cushion fan 5 to be in a 2-gear movement state, if the seat cushion temperature value is not lower than a second threshold value D and not higher than the first threshold value C, the control module controls the seat cushion fan 5 to be in a 1-gear movement state, and if the seat cushion temperature value is lower than the second threshold value D, the control module controls the seat cushion fan 5 to be turned off; if the temperature value of the backrest is higher than a third threshold value E, the control module controls the seat backrest fan 6 to be in a 2-gear movement state, if the temperature value of the backrest is not lower than a fourth threshold value F and not higher than the third threshold value E, the control module controls the seat backrest fan 6 to be in a 1-gear movement state, and if the temperature value of the backrest is lower than the fourth threshold value F, the control module controls the seat backrest fan 6 to be turned off; the relationship between the fan rotation speeds of the seat cushion fan 5 and the seat back fan 6 and the gear positions is such that the rotation speed in the 2-gear motion state is greater than the rotation speed in the 1-gear motion state. In Auto, the controller 1 controls the corresponding fan speed according to the temperature of the seat cushion and the backrest, and the fan speed increases as the temperature increases.
When the switch 3 is in the Hold gear, the Hold gear is a forced up-down gear, and the controller 1 receives temperature signals from the first temperature sensor 4 and the second temperature sensor 7 and judges a seat cushion temperature value and a backrest temperature value; if the seat cushion temperature value is higher than a first threshold value C, the control module controls the seat cushion fan 5 to be lowered to a 1-gear movement state, if the seat cushion temperature value is not lower than a second threshold value D and not higher than the first threshold value C, the control module controls the seat cushion fan 5 to be raised to a 2-gear movement state, and if the seat cushion temperature value is lower than the second threshold value D, the control module controls the seat cushion fan 5 to be turned off; if the temperature value of the backrest is higher than a third threshold value E, the control module controls the seat backrest fan 6 to be in a 1-gear movement state, if the temperature value of the backrest is not lower than a fourth threshold value F and not higher than the third threshold value E, the control module controls the seat backrest fan 6 to be in a 2-gear movement state, and if the temperature value of the backrest is lower than the fourth threshold value F, the control module controls the seat backrest fan 6 to be turned off. Under normal conditions, when the first temperature sensor 4 detects that the temperature is not higher than the first threshold C and not lower than the second threshold D, the rotation speed of the seat cushion fan 5 is reduced to the rotation speed of the 1 st gear, however, some passengers feel that the rotation speed of the fan in the 1 st gear cannot meet their requirements, and still want to want the fan to be in the 2 nd gear, at this time, the passengers turn the switch 3 to the "Hold" gear, the rotation speed of the fan is increased to the rotation speed of the 2 nd gear, and the same is true for the control process of the seat back fan 6; normally, when the first temperature sensor 4 detects that the temperature is higher than the first threshold C, the rotation speed of the seat cushion fan 5 is increased to the rotation speed of the 2 nd gear, but some passengers feel that the rotation speed of the fan in the 1 st gear is enough to meet their requirements, and then the passengers turn the switch 3 to the "Hold" gear, and the rotation speed of the fan is reduced to the rotation speed of the 1 st gear, and the same is true for the control process of the seat back fan 6. In the Hold gear, the controller 1 controls the corresponding fan rotating speed according to the temperatures of the seat cushion and the backrest, but compared with the Auto gear, the control corresponding relation between the fan rotating speed and the temperature is that the working temperature intervals of the fan 1 gear and the fan 2 gear are exchanged, so that another automatic control scheme for providing the fan rotating speed for passengers is selected, and the actual requirements of more passengers are met.
In addition, in the Auto gear and the Hold gear, the controller 1 can independently open and close the seat cushion fan 5 of the seat or adjust the rotating speed of the fan according to the temperature of the seat cushion, and the controller 1 can independently open and close the seat backrest fan 6 or adjust the rotating speed of the fan according to the temperature of the backrest; the independent control and regulation of the air quantity of the seat cushion and the air quantity of the backrest are realized, so that better comfort is brought to passengers.
When the switch 3 is in the "Off" gear, the controller 1 does not receive temperature signals from the first temperature sensor 4 and the second temperature sensor 7, and the control module controls the seat cushion fan 5 and the seat back fan 6 to be turned Off.
This application judges whether the seat is used, gathers seat seatpad temperature and seat back temperature through the signal that detection device provided to compare with the threshold value, thereby control opening of fan and stop with the wind speed, switch 3 has three shelves, wherein still including forcing the upshift and downshift, can satisfy passenger's various demands, realized that the vehicle is automatic to carry out ventilation control to the seat, improved the intelligence and the comfort level of vehicle, provide convenience for user's trip.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
