BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric vehicle having a solar tracking system,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric vehicle, and more particularly, to an electric vehicle including a solar location tracking system capable of accurately sensing the position of sunlight to follow solar power generation.

As society has developed and modernized, the development of alternative energy has become active due to the high oil prices and the depletion of fossil energy due to the increase in the usage of fossil energy, which was an existing energy source.

Among alternative energy sources, there is great interest in the field of solar energy that is pollution-free and can be used infinitely. Especially, solar power generation is a semiconductor device and the control unit is an electronic component. Therefore, there is no mechanical vibration or noise, the lifetime of the solar cell is long as several decades, the generation system can be semi-automated or automated, It is possible to minimize the cost incurred by the user.

In addition, solar power generation is not required for large-scale power generation facilities, and small-scale power generation is possible, so that it can be widely used for home use.

On the other hand, since the sun moves along the orbit during the time from sunrise to sunset, if the solar light unit is fixed at a predetermined position for a long time, solar heat can not be received under the optimum condition, and the efficiency of the system is lowered.

Therefore, it is known that solar heat can be taken under optimal conditions for a long time and the efficiency of the system can be increased if the solar heat-receiving apparatus including the solar panel receiving solar heat is traced along the moving orbit of the sun. For this reason, development of a solar locator is being actively carried out.

One example of a conventional solar tracker includes a current sensor for measuring the amount of electric power generated by receiving solar heat from a solar panel (condenser), and a current sensor for rotating the solar panel, that is, And a drive unit.

In such a configuration, the current measuring sensor and the like may have a large error depending on variables such as temperature, climate, and season, and it is difficult to normally track the position of the sun when a fault occurs.

Conventionally, the position of the sun is calculated by a program on a date and time basis, and an electronic compass or a tilt sensor is mounted on the solar panel so as to follow the calculated sun position to allow the solar panel to receive sunlight in an optimal state However, in this case, since the electronic compass or tilt sensor corresponds to the expensive equipment, the installation cost of the whole system is increased, and it is difficult to secure the normal operation of the heat exchanger in the event of failure of the electronic compass or tilt sensor .

Further, in the case of the electronic compass and tilt sensor, there is a problem that the energy consumption of the apparatus is increased due to driving control to continuously change the attitude of the solar panel during the nighttime from sunrise to sunrise.

In addition, a method of tracking the position of the sun using a light receiving sensor may be used. However, in this case, when foreign substances such as dust adhere to or accumulate in the light receiving sensor, an error occurs in the measured value, There was a problem.

In recent years, development and dissemination of electric vehicles have been actively carried out in order to reduce the use of fossil energy and to improve environmental pollution. In the case of such an electric vehicle, the electric energy charged in the battery is used as a power source by using a large capacity battery, and when using all the electric energy charged in the battery, it is troublesome to charge the battery at a separate charging station.

Considering these points, a technology for mounting a solar power generation device capable of generating electric power by using solar energy in an electric vehicle has been researched and developed. However, as described above, in this case, depending on the position of the electric vehicle or on the date and time Since the position of the sun is different, there is a problem that it is difficult to accurately track the sun position and absorb solar heat in the best state.

It is an object of the present invention to provide an electric vehicle having a sun position tracking system that can accurately track a sun position by a simple structure.

Here, the light-collecting plate position detecting unit includes a plurality of GPS receivers installed at different positions on the light-collecting plate, and each acquiring position information from a GPS satellite; And a position calculating unit for calculating an actual position (posture) of the light-condensing plate based on the coordinate values obtained from the plurality of GPS receivers.

The main control unit may further include a sunlight sensor installed on the vehicle body for detecting sunlight. The main control unit may control the lifting / It is preferable to control to be moved to be exposed to the outside.

Preferably, the ceiling of the automobile body is provided with a receiving portion in which the solar power generator is housed so as to be able to project and retract, and the receiving portion is selectively opened and closed by an opening / closing door provided on the automobile body.

The main control unit may compare the running speed of the vehicle detected by the running speed detecting unit with a reference speed, and only when the detected running speed is less than the reference speed, It is preferable that the solar power generation device is exposed to the outside of the automobile body to control the solar power generation.

According to the electric vehicle equipped with the solar locating system of the present invention, after the electric vehicle calculates the sun position theoretically by using the program in the state of the idling state, the position (posture) of the condenser is driven and controlled based on the theoretical value By increasing the efficiency of solar power generation, electric energy needed for electric vehicles can be supplied by itself.

Particularly, it is possible to control unnecessary operation by controlling the solar power generation device to perform the power generation operation by confirming the condition of the parking space of the vehicle and confirming the exposure condition of the sun, and to develop it only in the best time and condition, And efficient operation can be achieved.

The position (posture) of the measured light-collecting plate is compared with the theoretical value by measuring the actual position (posture) of the light-collecting plate by installing the light-collecting plate position detecting unit on the light-collecting plate and checking whether or not the actual light- And corrects the measured value to match the theoretical value when there is a difference between the theoretical value and the measured value, thereby enabling the condenser to always follow the sun precisely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electric vehicle including a solar tracking system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, an electric vehicle equipped with a solar tracking system according to an embodiment of the present invention includes a solar power generator 200 installed to be able to move into and out of a main body 10 of an automobile, A main sun position calculating unit 100 for calculating the sun position by theoretically calculating the sun position using the vehicle position detecting unit 120 for detecting the position of the vehicle, a traveling speed detecting unit 130, A sunlight sensing sensor 150, a condenser position detecting unit 300, an elevation driving unit 500 for raising and lowering the solar power generation apparatus 200, and a main control unit 400.

The receiving portion 11 may be provided on the upper portion of the automobile body 10, that is, on the ceiling, to allow the solar power generator 200 to protrude / retract. The entrance 13 is opened and closed. Therefore, the solar battery 200 can be exposed to the outside or closed by the opening / closing operation of the opening / closing door 12.

The operation of the opening / closing door 12 is controlled by the main control unit 400. The opening / closing door 12 may be operated to open / close the door 13 by a sliding operation. Alternatively, the opening / closing door 12 may be opened / closed like a sunroof installed in a vehicle. The construction of the opening / closing door 12 does not limit the present invention.

The solar power generator 200 is installed in the receiving portion 11 and is capable of protruding into and out of the receiving portion 11 and includes a condenser plate 210 and a condenser plate driving unit 220.

The light collecting plate 210 is used to absorb solar heat (light) to generate electric energy by using solar heat, and is driven by the driving unit 220 in two directions to follow the sun according to the sun position. That is, the light collecting plate 210 is rotatably driven about the second axis (Y axis) as the center of rotation according to the altitude of the sun, and rotates about the third axis (Z axis) The condensing surface of the condenser plate 210 is maintained in a vertical state with respect to the sunlight so that the mining efficiency is maintained at the maximum.

The light-condensing plate driving unit 220 includes a plurality of hydraulic cylinders 221 and 222, a rotation driving unit 223, and a rotary plate 224.

The rotation driving unit 223 is installed in the elevation driving unit 500 and rotationally drives the rotation plate 224 about the third axis (Z axis) so that the light collection plate 210 is rotated in the direction of the sun, Thereby making it possible to adjust the position in the direction. The rotation of the rotation driving unit 223 is also controlled by the main control unit 400.

The rotary plate 224 is installed at an upper portion of the rotary drive unit 223 and the rotary plates 224 are provided with the plurality of hydraulic cylinders 221 and 222 spaced apart from each other. In the embodiment of the present invention, a pair of hydraulic cylinders 221 and 222 are spaced apart from each other at positions symmetrical to each other with respect to the center of rotation of the rotary plate 224 so as to partially support the condenser plate 210 do. In this manner, the plurality of hydraulic cylinders 221 and 222 are installed and independently driven to be vertically adjustable in the third axis direction, whereby the light collecting plate 210 can be moved in the direction of the sun The posture can be adjusted in the direction of the hardness. That is, if only the left hydraulic cylinder 221 is driven to increase the length in the posture of FIG. 4, the posture of the condenser plate 210 can be changed to follow the sun in the posture as shown in FIG. The driving of the hydraulic cylinders 221 and 222 is precisely controlled by the main control unit 400 independently.

As shown in FIGS. 3 and 4, the elevating and lowering driving unit 500 is for elevating and lowering the solar power generator 200 so that the solar power generator 200 can be retracted into and out of the accommodating portion 11. In the present invention, It is to be understood that the present invention is not limited thereto. For example, another example of the lifting drive unit 500 may be a hydraulic cylinder, a lifting linear motor, a lead screw, or the like. In addition, various types of driving means may be employed.

Therefore, when it is determined that the solar power can be generated by using the solar heat, the main control unit 400 opens the opening / closing door 12 and then drives the elevation driving unit 500, The power generation device 200 is exposed to the outside of the vehicle body 10 as shown in FIG.

The vehicle position detecting unit 120 is provided in the vehicle body 10 to detect the position of the vehicle. The vehicle position detection unit 120 can detect the current position of the vehicle through satellite transmission / reception with the GPS satellite. The vehicle position information detected by the vehicle position detecting unit 120 is transmitted to the main sun position calculating unit 100.

The main sun position calculation unit 100 calculates and calculates the sun position based on the measurement date, time, and vehicle position input through the input unit 110 using a preset sun position calculation program. Here, the method of calculating the sun position using the sun position calculation program is generally known and can be automatically calculated by computer programming. In this manner, the main sun position calculating unit 100 calculates the theoretical value of the sun position on the basis of the current position of the vehicle, and the calculated theoretical value is transmitted to the main control unit 400.

4, the main controller 400 controls the rotation drive unit 223 and the pair of hydraulic cylinders 223 and 223 based on the theoretical value of the sun position transmitted from the main sun position calculation unit 100 as time elapses from the initial state as shown in FIG. So that the sun position of the condenser plate 210 can be precisely followed.

The driving unit 220 is driven and controlled by the main control unit 400 so as to correct the posture of the condenser 210 according to the actual position of the condenser plate 210 detected by the condenser position detecting unit 300 do.

The light-collecting plate position detecting unit 300 is for measuring the position (posture) taken by the actual light-collecting plate 210 according to the actual position of the light-collecting plate 210, that is, the position of the sun. The light-collecting plate position detecting unit 300 includes a plurality of GPS receiving units 310, 320, and 330 and a position calculating unit 350. The plurality of GPS receiving units may include first to third GPS receiving units 310, 320, and 330, and at least two of them may be installed at different positions on the same plane of the condensing plate 210. The first to third GPS receiving units 310, 320, and 330 acquire respective position values, i.e., coordinate values through transmission / reception with the GPS satellite, and the obtained X, Y, Z coordinate values are input to a position calculating unit 350).

5 and 6, the first and second GPS receiving units 310 and 320 are spaced apart from each other in the X-axis direction and are disposed on the same axis line in the Y-axis direction. The third GPS receiving unit 330 is spaced apart from the first receiving units 310 and 320 in the X axis and Y axis directions and spaced apart from the second GPS receiving unit 320 only in the Y axis direction, do.

Accordingly, the first to third GPS receiving units 310, 320, and 330 are arranged to have different three-dimensional coordinate values. When the position of the light condensing plate 210 is changed by the driving unit 220, the three-dimensional coordinate values of the first to third PSPS receiving units 310, 320 and 330 are changed, and the changed three- And can be acquired through the GPS satellites in the receiving units 310, 320, and 330, respectively. The three-dimensional coordinate values obtained by the GPS receiving units 310, 320, and 330 are transmitted to the position calculating unit 350.

The position calculating unit 350 calculates the altitude and the hardness based on the actual position of the condenser plate 210, that is, the sun position, based on the coordinate values detected by the first to third PSPS receiving units 310, 320 and 330 .

First, when the light collecting plate 210 is rotated about the Y axis in the state of FIG. 4, the posture changes to the state of FIG. At this time, the topology position calculation unit 350 obtains the altitude value? 2 taken by the condenser plate 210 with the coordinate values obtained by the first and second GPS receiving units 310 and 320. Here, instead of the angle? 2,? 1 may be obtained as an altitude value. The altitude value 2 can easily calculate and calculate the altitude value 2 by obtaining the distance d between the first and second GPS receiving units 310 and 320 and the coordinate values of the GPS receiving units 310 and 320. Since the altitude value 2 varies corresponding to the rotation angle about the second axis Y of the condenser plate 210, the position (attitude) of the actual condenser plate 210 relative to the sun can be calculated.

5, when the rotation driving unit 223 rotates the rotary plate 224 about the Z axis by the control signal of the main control unit 400 to follow the direction of the sun (in this case, 5 and 6, the first and third 3GPPS signals are generated in accordance with the angle of rotation of the condenser plate 210 in the states of FIGS. 7 and 8 at the positions of FIGS. 5 and 6, The direction value 3 between the first and third GPS receiving units 310 and 330 is changed and the changed direction value 3 can be calculated by obtaining the actual coordinate values of the first and third GPS receiving units 310 and 330. [ Assuming that the states of FIGS. 5 and 6 are initial states, the direction value '? 3 = measured value?' Is obtained in the states of FIGS. 7 and 8 when the direction value is? 3 = 0 in the initial state do.

By providing a plurality of GPS receivers 310, 320 and 330 on the light collecting plate 210 as described above, the position and attitude of the actual light collecting plate 210 can be calculated through the position calculating unit 350.

The actual position information (measured value) of the condensing plate 210 calculated by the position calculating unit 350 is transmitted to the main control unit 400.

The main controller 400 initially controls the drive unit 220 so as to follow the sun in an optimum state on the basis of the sun position value (theoretical value) calculated by the main sun position calculating unit 100 The position of the condenser plate 210, that is, the posture, is adjusted to the sun position according to the position, date, and time of the vehicle.

The main control unit 400 compares the measured value of the actual position (posture) of the condenser plate 210 calculated and transmitted by the position calculating unit 350 with the theoretical value calculated by the main sun position calculating unit 100 . When there is a difference between the measured value and the theoretical value of the comparison result, the position (attitude) of the condenser plate 210 is corrected by controlling the driving unit 220 so that the measured value matches the theoretical value.

Therefore, the sunlight can be absorbed in the best state by always following the sun position exactly following the sun position, and even if the driving unit 220 malfunctions or a driving error occurs, the light-condensing plate position detection unit 300 The difference value due to such malfunction or drive error can be detected and corrected.

When the difference between the measured value and the theoretical value detected by the light-condensing plate position detecting unit 300 is too large, that is, when the difference between the measured value and the theoretical value is more than 10%, the main control unit 400 And make follow-up measures to be taken. That is, when it is confirmed that the drive unit 220 has failed, the main control unit 400 transmits the failure occurrence information of the drive unit to the manager's terminal or the management server of the management center through an unillustrated transmitting unit, The center can recognize this and repair or replace the fault.

Here, the main control unit 400 corrects the position of the condenser plate 210 based on the result of detecting the actual position of the condenser plate 210 during the solar thermal power generation in the vehicle idling state. As will be described later in detail, In the case of performing solar power generation while traveling at a low speed less than the predetermined reference speed, the correction of the position of the condenser plate 210 can be omitted.

The differential detection sensor 140 is installed in the vehicle body 10 to detect the parking or stopping state of the vehicle. Such a parking sensor 140 may include a parking brake operation detection sensor generally used in automobiles and may include an engine drive detection sensor that can detect a parking state of the vehicle even when the vehicle engine is stopped. have. In addition, various kinds of detection sensors capable of detecting the state of the vehicle on the road can be applied.

The solar photodetection sensor 150 is installed in the vehicle body 10 and can detect sunlight, that is, visible light, to see whether the sun is exposed or whether the sun is in a cloud or in a building. The result detected by the solar photodetection sensor 150 is transmitted to the main control unit 400. Accordingly, the main control unit 400 can perform the solar power generation when the vehicle is in the state of a parked vehicle and the solar light sensor 150 does not detect sunlight or detects a sunlight below the reference amount, So that the solar power generation operation using the solar power generator 200 is not performed. That is, when the vehicle is parked in an underground parking lot, or is parked on the shade where the sun is blocked by a building, or the weather is cloudy and the sun is not exposed, the solar- It is meaningless to expose to the outside.

According to the embodiment of the present invention, it is preferable to further include a traveling speed detecting unit 130 for detecting the traveling speed of the vehicle. The traveling speed detection unit 130 detects the traveling speed in a state where the vehicle is running, and the detected traveling speed information is transmitted to the main control unit 400.

The main control unit 400 compares the traveling speed of the vehicle detected by the traveling speed detecting unit 130 with the reference speed and only when the detected traveling speed is less than the reference speed, So that the solar power can be controlled to be generated. That is, for example, if the reference speed is set to 50 km, if the vehicle travels less than 50 km, even if the solar power generator 200 is exposed to the outside of the vehicle body 10, The vehicle position detecting unit 120 detects the change in the vehicle position in real time and transmits the detected change value to the main sun position calculating unit 100 so that the vehicle can be steered at a low speed It becomes possible to adjust the position (posture) of the light condensing plate 210 corresponding to the movement of the vehicle. As described above, the reference speed can be set to an appropriate criterion according to variables such as the type of the vehicle, the service area of the vehicle, the season, and the like.

As described above, in the case of an electric vehicle equipped with a solar tracking system according to an embodiment of the present invention, it is possible to perform an operation for making solar power generation in the state of a pseudo-electric vehicle of a vehicle, As shown in FIG.

Accordingly, the operation of the electric vehicle having the solar locating system according to the embodiment of the present invention having the above-described configuration will be described in detail as two cases.

First, the operation of the vehicle in the idling state will be described in detail with reference to FIGS. 1 to 9. FIG.

First, the electric vehicle is operated (S10), and the state detection sensor 140 detects whether or not the vehicle is parked (S11).

If it is determined in step S11 that the vehicle is in an idling state, the main control unit 400 determines whether sunlight is detected by the solar light sensor 150 (S12).

When it is confirmed in step S12 that the sunlight is detected, the main control unit 400 moves and opens the opening / closing door 12 as shown in FIG. 3, drives and controls the elevation drive unit 500, The solar power generator 200, that is, the condenser plate 210 is moved so as to be exposed out of the vehicle (S13).

In addition, the vehicle position detecting unit 120 detects the current position of the vehicle through communication with the GPS satellite and transmits the detected current position to the main sun position calculating unit 100 (S14).

The main sun position calculating unit 100 calculates a theoretical value of the sun position based on the transmitted vehicle position value with reference to the vehicle, that is, the condenser 210 (S15).

The theoretical value calculated by the main sun position calculation unit 100 is transmitted to the main control unit 400 and the main control unit 400 adjusts the position of the light collecting plate 210 so as to follow the sun based on the received theoretical value S16).

In the state where the light collecting plate 210 is adjusted, the light collecting plate position detecting unit 300 detects (measures) the actual position value of the light collecting plate 210 (S17).

The actual position value of the condenser plate 210 detected by the condenser position detector 300 is transmitted to the main controller 400 and the main controller 400 compares the measured value with the theoretical value (S18).

The main control unit 400 drives and controls the driving unit 220 so that the actual position of the condenser plate 210 is the same as the theoretical value, The position is corrected so as to have a posture corresponding to the theoretical value (S19). By correcting the position of the light collecting plate 210 to match the theoretical value in this way, even if a failure or malfunction of the drive unit 220 or a drive error of the drive unit 220 occurs, the light collecting plate 210 always controls the sun accurately .

Since the installation position information and the date and time information of the condenser plate 210 can be known, an accurate time from the sunrise time to the sunset time is secured to limit the driving time of the condenser plate 210 and the drive unit 220 The control for the drive unit 220 and the condenser plate 210 is stopped from the sunset time to the sunrise time, thereby reducing the maintenance cost and the maintenance cost.

As described above, since the actual position (posture) of the condenser plate 210 can be detected by using the condenser position detector 300 installed in the condenser 210, the measured values and theoretical values can be compared with each other It is possible to determine whether or not the condenser plate 210 is position-controlled in accordance with the control signal, and when there is a difference, the condenser plate 210 can be controlled so as to follow the sun precisely at all times, There is an advantage to be able to do.

In addition, unnecessary operations can be prevented from being performed in actual flowing weather, sound, buildings, etc. by allowing the solar power generator 200 to be exposed to the outside of the vehicle only in an environment in which the vehicle is parked and sunlight is detected .

In the meantime, when the vehicle is in operation and is below the reference speed, it is possible to generate solar heat. Such a case will be described in detail with reference to FIG. 1 to FIG. 8 and FIG.

First, the vehicle is in operation (S20). In this state, the traveling speed detector 130 detects the traveling speed of the vehicle (S210).

The detected traveling speed is transmitted to the main control unit 400. The main control unit 400 compares the detected traveling speed of the vehicle with a predetermined reference speed to determine whether the vehicle is traveling below the reference speed (S22).

If it is determined in operation S22 that the vehicle is traveling below the reference speed, the main control unit 400 determines that the solar power generation operation can be performed and opens the opening / closing door 12 as described above, (210) is moved out of the vehicle and exposed (S23).

Then, the car position detecting section 120 detects the position of the vehicle (S24), and the detected vehicle position data is transmitted to the main sun position calculating section 100. [

The main sun position calculation unit 100 calculates the position of the sun with reference to the light collecting plate 210 on the basis of the vehicle position data received (S25).

The main control unit 400 adjusts the position of the condenser plate 210 according to the theoretical value calculated by the main sun position calculation unit 100 (S26). Therefore, while the vehicle is running at a low speed below the reference speed, the solar panel 210 can be controlled to follow the sun position, and the solar heat generation operation can be performed by absorbing the solar heat to the maximum.

That is, when the vehicle runs at a low speed on a highway traveling in one direction, or in a congested section, solar power generation can be performed, so that the electric energy necessary for the operation of the electric vehicle can be generated and charged.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Those skilled in the art will readily appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
