8 is a control flowchart of a vehicle according to an embodiment.

The vehicle checks the wheel speed information detected by the plurality of wheel speed detection units and the acceleration information from the acceleration detection unit, and determines whether it is time to apply driving force to the vehicle using the motor provided in the wheel based on the wheel speed information and acceleration information. Determine whether it is time to apply regenerative braking force.

When the vehicle determines that it is time to apply driving force to the vehicle, it converts the power of the battery 250 into the power necessary to drive the motor 240 and applies the converted power to the motor 240, causing the motor 240 to rotate. .

At this time, when the motor 240 rotates, rotational force is transmitted to the second gear 241 connected to the motor shaft of the motor, causing the second gear 241 to rotate. And, as the second gear 241 rotates, the meshing position of the second gear 241 and the first gear 211 changes, causing the wheel to rotate. That is, the vehicle can use the rotational force of the motor 240 as driving force for the wheels.

When the vehicle determines that it is time to apply regenerative braking force to the vehicle, the force acting on the motor 240 acts in the reverse direction so that the motor 240 can operate as a generator. At this time, the battery 250 may be charged by power applied through the motor 240 that functions as a generator.

The vehicle periodically checks the charging state of the battery regardless of the operating state of the motor 240, and if the charging amount of the battery 240 corresponding to the confirmed charging state is a preset allowable charging amount, the battery is maintained even if regenerative braking is performed. Stop charging.

If the charge of the battery 240 corresponding to the confirmed charging state is less than the allowable discharge amount, the battery is charged by regenerative braking and applies driving force to the vehicle using the motor 240 until the battery charge reaches the allowable charge. Stops the function.

That is, the vehicle stops the operation of the motor 240 when the charge of the battery 240 is less than the allowable discharge amount, and applies driving force to the vehicle when the charge of the battery becomes more than the allowable charge after the battery is charged by regenerative braking. The motor 240 can be operated for this purpose.

The vehicle checks (301) the charge amount of the battery 240 corresponding to the charge state of the confirmed battery and compares the charge amount of the confirmed battery with the reference charge amount.

The vehicle determines (302) whether the battery charge is greater than or equal to the standard charge, and if it is determined that the battery charge is less than the standard charge, operates only the motor 240.

That is, when the vehicle determines that the battery charge is less than the standard charge, the vehicle provides power from the battery 250 only to the motor 240 among the components provided inside the wheel 210, so that only the function of applying driving force to the vehicle is performed. At this time, the power of the battery supplied to the air purification unit 280 is cut off to prevent the air purification function from being performed within the wheel.

Here, the reference charge amount may be a charge amount lower than the allowable charge amount or a charge amount higher than the allowable discharge amount.

When the vehicle determines that the battery charge is greater than the standard charge, the vehicle checks the pollution level detected by the pollution level detection unit (303).

Here, checking the pollution level includes checking any one of the pollution level corresponding to the amount of dust, the pollution level corresponding to the amount of harmful gas, and the pollution level corresponding to the amount of dust and the amount of harmful gas.

The vehicle compares the confirmed pollution level with the standard pollution level and determines whether the confirmed pollution level is higher than the standard pollution level (304). If it is determined that the confirmed pollution level is less than the standard pollution level, it determines that air purification is unnecessary and operates the air purification unit (280). Turn it off.

If the vehicle determines that the confirmed pollution level is higher than the standard pollution level, it checks the speed of the wheels (305).

Here, checking the speed of the wheel includes checking the speed of the wheel on which the air purification unit is disposed. That is, checking the speed of the wheel includes checking the speed of the non-driving wheel.

The vehicle compares the confirmed wheel speed with the reference wheel speed and determines whether the confirmed wheel speed is greater than or equal to the reference wheel speed (306).

If the vehicle determines that the confirmed wheel speed is less than the reference wheel speed, the vehicle determines that the wheel 210 is not performing the fan function and turns off the operation of the air purification unit 250 to prevent the air purification function from being performed. Afterwards, the vehicle periodically checks the speed of the wheels.

In this way, when the wheel 210 does not perform the function of a fan, an air flow path is not created by the first cover of the wheel, and as a result, air is not sucked into the inside of the wheel or the amount of air sucked is very small. In addition, air is not discharged to the outside of the wheel or the amount of air discharged is very small, so even when the air purification unit is operated, the air purification performance is low. For this reason, the vehicle may stop the operation of the air purification unit.

Here, determining that the confirmed wheel speed is less than the reference wheel speed may include determining that the flow of air inside the wheel is in a stagnant state.

In addition, the state of the vehicle when the confirmed wheel speed is less than the reference wheel speed may include a low-speed driving state or a stopped state.

If the vehicle determines that the confirmed wheel speed is higher than the reference wheel speed, the vehicle determines that the wheel 210 performs the function of a fan and purifies the air by electrostatic dust collection by applying positive and negative electricity to the high voltage generator of the air purification unit. Perform (307).

In this way, when the wheel 210 performs the function of a fan, an air flow path is created by the first cover of the wheel, which causes air to be sucked into the inside of the wheel, and the air sucked inside the main body of the wheel is air. After passing through the purification unit 280, it can be discharged to the outside of the wheel through the second cover.

When air passes through the air purification unit 280, dust or impurities in the air are charged by the discharge member, and the charged dust or impurities may attach to the dust collection member of the air purification unit 280.

At this time, only neutral air can be discharged to the outside of the air purification unit 280 and into the space inside the main body, and the purified air existing in the inner space of the wheel can be discharged to the outside of the wheel.

In this way, this embodiment can compress, flow, and collect external air through the rotation of a wheel formed in a fan shape, thereby increasing the efficiency of air purification, and effectively removing contaminants in the air on the road using electric dust collection. can do.

Additionally, this embodiment can change the image of internal combustion engine vehicles, which are recognized as the main cause of environmental pollution due to exhaust gases, and improve vehicle performance by assisting the driving force of the vehicle using motors provided in the wheels.

This embodiment can remove fine dust and pollutants in the air, thereby protecting people's health.
