When driving at high speed or turning, the driving speed of the vehicle does not increase and the driving stability deteriorates as the grip force of the rear tires is weakened. In order to solve this problem, as disclosed in Patent Document 1, an air spoiler is installed at the rear of the vehicle. By changing the flow of air passing through the vehicle by the air spoiler, it is possible to generate pressure (aerodynamic force) that presses the vehicle according to the air flow around the air spoiler. Through this, by improving the grip of the rear tire, it is possible to improve driving force and braking force by compressing the vehicle to the road surface.

Therefore, in addition to such limited power, a demand for power supply from an auxiliary power source is increasing.

Solar cells are attracting the most attention as such an auxiliary power source. When the solar cell is attached to the outer surface of the vehicle, solar power generation is possible using sunlight or artificial visible light while the vehicle is running as well as while the vehicle is stopped. The generated power can be charged in a battery and used to drive an engine, convenience devices such as AVs, or air conditioners, or can be used as an auxiliary power source for electric vehicles.

In particular, in the prior art disclosed in Patent Literature 2 or the like, a technology is disclosed in which the aerodynamics improvement effect and the photovoltaic power generation function of the spoiler are simultaneously performed by mounting the solar cell on the upper part of the rear spoiler of the vehicle.

And, as shown in FIG. 11, when switching from the (a) state in which the outer spoiler 100 is deployed to the stowed state, first, as shown in (b), the inner spoiler 200 After descending and the inner spoiler 200 descends to a predetermined position, as shown in (c), the outer spoiler 100 slides into a stored state.

Hereinafter, a spoiler control method according to the present invention will be described with reference to FIG. 12 .

First, in order to determine whether the outer spoiler unit 100 is deployed or stored, the control unit receives illumination information and vehicle speed information from an illumination intensity sensor and a vehicle speed sensor installed in the vehicle (S10), and compares the received vehicle speed information with a predetermined threshold. A vehicle speed value is prepared (S20).

As a result of the determination in step S20, when it is determined that the current vehicle speed exceeds a predetermined threshold vehicle speed value, it is necessary to increase the gripping force of the vehicle by generating downforce, so the spoiler deployment signal is transmitted to the electromagnet of the lifting mechanism 400 ( 410) (S30).

When receiving a spoiler deployment signal from the control unit, the electromagnet 410 of the lifting mechanism 400 generates a magnetic field to lower the inner spoiler unit 200 (S40).

When the inner spoiler 200 descends below a certain height, the lower surface of the inner spoiler 200 comes into contact with the switch 430, and at this time, the switch 430 turns on the motor 320 of the drive unit 300. to unfold the outer spoiler unit 100 (S50).

And, when the outer spoiler unit 100 reaches the fully deployed position, the spoiler fixing link 332 comes into contact with the switch 340, and at this time, the switch 340 drives the electromagnet 410 of the lifting mechanism 400. turn off When the driving of the electromagnet 410 is turned off, the inner spoiler unit 200 is raised by the elastic member 420 of the lifting mechanism 400 (S60). Accordingly, in a state in which the outer spoiler unit 100 is deployed, both the solar cell 110 mounted on the outer spoiler unit 100 and the solar cell 120 mounted on the inner spoiler unit 200 start solar power generation. do.

On the other hand, even when the vehicle speed is less than the critical vehicle speed value and there is no need to deploy the outer spoiler unit 100 in terms of vehicle grip, the outer spoiler unit 100 is operated to secure sufficient power if the current weather is in a state of high illumination. need to evolve.

Accordingly, when the vehicle speed is less than or equal to the threshold vehicle speed value in step S20, the control unit determines whether the current illumination intensity exceeds the threshold illumination intensity value by using the illumination intensity information received in step S10 (S70).

As a result of the determination, when it is determined that the current illuminance exceeds the threshold illuminance value, the process proceeds to step S30 to unfold the outer spoiler unit 100.

Meanwhile, in a state where the vehicle speed is less than the critical vehicle speed value but the current illumination exceeds the threshold illumination value and the outer spoiler unit 100 is deployed, when the illumination decreases due to a change in weather, the outer spoiler unit 100 is operated again. It is necessary to switch to storage state.

Therefore, in this case, the controller first transmits a spoiler storage signal to the electromagnet 410 of the lifting mechanism 400 (S80).

When the electromagnet 410 of the lifting mechanism 400 receives a spoiler storage signal from the control unit, a magnetic field is generated to lower the inner spoiler unit 200 (S90).

When the inner spoiler 200 descends below a certain height, the lower surface of the inner spoiler 200 comes into contact with the switch 430, and at this time, the switch 430 turns on the motor 320 of the drive unit 300. to accommodate the outer spoiler unit 100 (S100).

And, when the outer spoiler unit 100 reaches the completely retracted position, the belt fixing link 331 comes into contact with the switch 350, and at this time, the switch 350 drives the electromagnet 410 of the lifting mechanism 400. turn off When the driving of the electromagnet 410 is turned off, the inner spoiler unit 200 is raised by the elastic member 420 of the lifting mechanism 400 and maintained at a predetermined standby position (S60).

On the other hand, if the position of the inner spoiler 200 is maintained for a long period of time in the stored state, it is necessary to switch the battery charging mode by solar energy to the sleep mode from the viewpoint of reducing power consumption.

Therefore, the control unit measures the time the inner spoiler unit 200 is maintained in the stored state, determines whether the stored state maintenance time exceeds a threshold value (S120), and if it exceeds, the battery charging mode by solar energy Converts to sleep mode (S130).

According to the spoiler and its control method according to the present invention described above, when the vehicle speed exceeds the critical vehicle speed value and it is necessary to increase the gripping force of the vehicle, or when a large amount of solar energy can be converted into electric power due to high illumination, the outer spoiler By using the unit 100, it is possible to simultaneously achieve the effect of increasing the aerodynamic force through the deployment of the spoiler and the increase in the amount of solar energy capture according to the increase in the area exposed to sunlight.
