[0060] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0061] References to "one embodiment" or "example" or "example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0062] Charging piles occupy a small area. In order to solve the problem of insufficient charging piles in service areas, charging devices can be set up on the roadside. When driving new energy vehicles for long-distance travel, the charging time is required to be shorter and the charging amount is required to be higher. Accordingly, charging devices are set up on the roadside of highways outside service areas to facilitate the charging of new energy vehicles traveling long distances.

[0063] Roadside (especially highway side) is a dangerous area, and setting up charging equipment directly on the roadside may cause traffic accidents. In other words, although setting up charging equipment directly on the roadside can solve the problem of insufficient charging piles in service areas, it also causes the problem of unsafe charging.

[0064] In view of this, as a first aspect of the present invention, a control method for a photovoltaic charging system is provided, which is used for a controller of the photovoltaic charging system, wherein: Figure 1 As shown, the control method includes:

[0065] In step S110, in response to a first sensing signal indicating that the vehicle is located at a vehicle handover position, a first control signal is sent to a platform driving device of the photovoltaic charging system, so that the platform driving device drives the vehicle transfer platform of the photovoltaic charging system to move to the vehicle handover position, and drives the vehicle transfer platform to move the vehicle to a set charging position;

[0066] In step S120, in response to the charging end signal, a second control signal is sent to the platform driving device, so that the platform driving device drives the vehicle transfer platform to move the vehicle to the vehicle handover position;

[0067] In step S130, in response to the second sensing signal indicating that the vehicle leaves the vehicle transfer platform, a third control signal is sent to the platform driving device, so that the platform driving device drives the vehicle transfer platform to move to a set storage position.

[0068] The control method provided by the embodiment of the present invention is executed by the controller of the photovoltaic charging system provided by the embodiment of the present invention (ie, the controller 300 described below).

[0069] like Figure 2 As shown, the photovoltaic charging system includes a photovoltaic assembly 100, a charging device 200, an adaption module 400, a controller 300, an induction module 800, a vehicle transfer platform 600 and a platform driving device 500. After the photovoltaic assembly 100 generates electricity, it can supply power to the charging device 200, thereby charging vehicles with charging needs.

[0070] The photovoltaic charging system provided in the embodiment of the present invention is arranged on one side of the road. When there is no vehicle to be charged, the vehicle transfer platform 600 is in a storage position away from the road to avoid affecting road traffic. When the vehicle needs to be charged, the driver drives the vehicle to the vehicle handover position near the photovoltaic charging system. After the sensing module detects the vehicle to be charged, it generates the first sensing signal and sends it to the controller 300. As described above, the controller 300 sends a first control signal to the platform drive device 500 in response to the first sensing signal. After receiving the first control signal, the platform drive device 500 drives the vehicle transfer platform 600 to move to the vehicle handover position. The driver drives the vehicle to the vehicle transfer platform 600 located at the vehicle handover position, and the vehicle transfer platform 600 transfers the vehicle to the set charging position, so that the vehicle is charged using the charging device set at the set charging position.

[0071] After charging is completed, the controller 300 sends a second control signal to the platform driving device 500, and the platform driving device 600 drives the vehicle transfer platform 600 to move the vehicle to the vehicle handover position according to the second control signal.

[0072] After the vehicle arrives at the vehicle handover position, the driver drives the vehicle away from the vehicle transfer platform 600. In this case, the sensing module generates a second sensing signal. After receiving the second sensing signal, the controller 300 sends a third control signal to the platform driving device 500, and finally uses the platform driving device 500 to drive the vehicle transfer platform 600 back to the set storage position away from the road.

[0073] The photovoltaic charging system provided in the embodiment of the present invention can be set up in a safe location beside a road (for example, a highway). When there is no vehicle charging, the entire photovoltaic charging system is at a safe distance from the edge of the road. When a vehicle needs to be charged, the vehicle is transferred to the safe location for charging, which can not only charge the vehicle and supplement the problem of insufficient charging devices in the service area, but also will not affect traffic safety and improve charging safety.

[0074] In the embodiment of the present invention, there is no special limitation on how to generate the "charging end signal". For example, charging can be terminated manually, and accordingly, the charging device generates the "charging end signal". For example, the charging end signal can be generated when it is detected that the charging device charges the vehicle to a set value. For another example, the charging end signal can be generated by software control.

[0075] In the embodiment of the present invention, no special limitation is imposed on the relationship among the "vehicle handover position", the "set charging position" and the "set storage position", and how the vehicle transfer platform moves between the above three positions.

[0076] As an optional embodiment, the vehicle transfer platform includes a load-bearing platform and at least one retractable guide rail. The load-bearing platform is arranged on the retractable guide rail and can move with the extension and retraction of the retractable guide rail. The load-bearing platform is respectively located at both ends of the retractable guide rail. The first control signal is used to enable the platform driving device to drive the retractable guide rail to first extend from a first contracted state to an extended state, and then retract from the extended state to the second contracted state. When the retractable guide rail is in the first contracted state, the vehicle transfer platform is located at the set storage position. When the retractable guide rail is in the extended state, the vehicle transfer platform is located at the vehicle handover position. When the retractable guide rail is in the first contracted state, the vehicle transfer platform is located at the set charging position.

[0077] The retractable guide rail is easy to control, and the control method can be made easier to implement by means of a "carrying platform" plus a "retractable guide rail".

[0078] In the embodiment of the present invention, there is no special limitation on the first contracted state and the second contracted state. As an optional implementation, in the first contracted state and the second contracted state, the length of the retractable rail is different. Of course, for the convenience of control, optionally, in the first contracted state and the second contracted state, the length of the retractable rail is the same, that is, the set storage position and the set charging position can be the same position.

[0079] As another optional implementation, the vehicle transfer platform includes a load-bearing platform 610, a lifting mechanism 650, and at least one retractable guide rail 620, the load-bearing platform 610 is disposed on the lifting mechanism 650 and can be raised and lowered with the lifting mechanism 650, and the lifting mechanism 650 is disposed on the retractable guide rail 620 and can move with the extension and retraction of the retractable guide rail 620.

[0080] The vehicle handover position and the set charging position are respectively located at two ends of the telescopic guide rail 620 , and the set storage position and the set charging position are located at the same end of the telescopic guide rail 620 .

[0081] It should be explained that the photovoltaic charging system generally further includes a main body shell 700, and at least a portion of the photovoltaic assembly is disposed on the top of the main body shell 700. In the embodiment of the present invention, the charging device 200 is disposed in the main body shell 700 near the top of the main body shell 700, and there is a height difference with the ground. Accordingly, in order to reduce the length of the cable in the charging device, the height of the set charging position is also higher than the ground.

[0082] When there is no need to transfer or charge the vehicle, the vehicle transfer platform 600 is stored in the "set storage position". In order to improve storage safety and simplify the operation process of driving the vehicle transfer platform 600 to transfer, the set storage position is optionally located on the ground. In other words, in the embodiment of the present invention, the height of the set storage position is lower than the height of the set charging position.

[0083] When the retractable guide rail 620 is in the first retracted state and the lifting mechanism is in the low position, the vehicle transfer platform is located at the set storage position; when the retractable guide rail is in the extended state and the lifting mechanism is in the low position (see Figure 2 ), the vehicle transfer platform is located at the vehicle handover position, and when the retractable guide rail is in the second retracted state and the lifting mechanism is in a high position, the vehicle transfer platform is located at the set charging position.

[0084] In step S110, sending a first control signal to the platform driving device of the photovoltaic charging system so that the platform driving device drives the vehicle transfer platform of the photovoltaic charging system to move to the vehicle handover position, and drives the vehicle transfer platform to move the vehicle to the set charging position can be specifically executed as follows: sending a first control signal to the platform driving device of the photovoltaic charging system so that the platform driving device drives the retractable guide rail to first extend from a first contracted state to an extended state, and then retract from the extended state to the second contracted state.

[0085] In step S120, sending a second control signal to the platform driving device so that the platform driving device drives the vehicle transfer platform to move the vehicle to the vehicle handover position can be specifically performed as follows: sending a second control signal to the platform driving device so that the platform driving device drives the retractable guide rail to extend from the second retracted state to the extended state;

[0086] In step S130, sending a third control signal to the platform driving device so that the platform driving device drives the vehicle transfer platform to move to a set storage position can be specifically executed as follows: sending a third control signal to the platform driving device so that the platform driving device drives the retractable guide rail to retract from the extended state to the first contracted state.

[0087] As an optional implementation, the adapter module 400 of the photovoltaic charging system may include a power storage unit 410 , and the electric energy generated by the photovoltaic assembly 100 is directly stored by the power storage unit 410 , and the power storage unit 410 is used to supply power to the charging device 200 .

[0088] As an optional implementation, the power storage unit 410 may be a battery.

[0089] In the embodiment of the present invention, there is no special limitation on the capacity of the power storage unit 410. Optionally, the capacity of the power storage unit 410 should be greater than or equal to the sum of the power stored in the power storage unit and the maximum power generation of the photovoltaic module.

[0090] For the photovoltaic charging system, there are not always vehicles charging here. In order to make full use of the electric energy generated by the photovoltaic assembly 100, as an optional implementation, Figure 3 As shown, the control method also includes:

[0091] In step S140, when the remaining power of the power storage unit of the current photovoltaic charging system is lower than a first power threshold, the photovoltaic assembly is controlled to store the generated electric energy into the power storage unit of the current photovoltaic charging system, wherein the first power threshold is not lower than the single-use power of the charging device of the photovoltaic charging system;

[0092] In step S150, when the remaining power of the storage unit of the current photovoltaic charging system is higher than a second power threshold, the photovoltaic assembly is controlled to transmit the generated electric energy to the storage unit of the adjacent photovoltaic charging system, wherein the first power threshold is lower than the second power threshold.

[0093] That is to say, if the remaining power of the storage unit of the current photovoltaic charging system is low, the electric energy generated by the photovoltaic component 100 can be directly stored in the storage unit of the current photovoltaic charging system; if the remaining power of the storage unit of the current photovoltaic charging system is high, power can be supplied to the adjacent photovoltaic charging system to improve the utilization rate of the power generated by the photovoltaic component.

[0094] If the remaining power of the storage unit of the adjacent photovoltaic charging system is also high, the electrical energy generated by the photovoltaic components can be provided to the grid.

[0095] That is to say, the control method may further include:

[0096] In step S160, when the power level of the storage unit of the adjacent photovoltaic charging system is higher than the third power level threshold, the storage unit of the current photovoltaic charging system is controlled to transmit the electric energy generated by the photovoltaic components to the inverter of the current photovoltaic charging system, so that the inverter converts the direct current of the storage unit into alternating current and transmits it to the power grid.

[0097] This is equivalent to using the inverter of the current photovoltaic charging system to convert the direct current generated by the photovoltaic modules into alternating current and provide it to the power grid.

[0098] It should be pointed out that although Figure 3 In the figure, steps S140 to S160 are connected by a downward arrow, but this does not indicate the execution order of steps S140 to S160.

[0099] In the embodiment of the present invention, there is no special limitation on the specific value of the third power threshold. For example, the third power threshold may be 80% to 100% of the rated power storage unit.

[0100] There are multiple peaks of electricity consumption in a period of time. In order to better meet the needs of electricity users, relieve the pressure of the power grid, and avoid power shortages, the control method may also include:

[0101] When the current time period belongs to the peak power consumption of the power grid and the remaining power of the power storage unit of the current photovoltaic charging system is greater than the fourth power threshold, the power storage unit of the current photovoltaic charging system is controlled to transmit electric energy to the inverter, so that the inverter converts the direct current output of the power storage unit into alternating current and transmits it to the power grid, wherein the fourth power threshold is higher than the first power threshold.

[0102] In the embodiment of the present invention, there is no special limitation on how to determine whether the current period belongs to the peak power consumption period. As an optional implementation, the peak power consumption period can be preset. As long as the remaining power in the power storage unit exceeds the fourth power threshold, the power generated by the photovoltaic module 100 can be charged into the power storage unit, and then the surplus power in the power storage unit can be transmitted to the power grid through the inverter.

[0103] It should be noted that once the remaining power in the storage unit is not lower than the fourth power threshold during the peak power consumption period, the power supply to the inverter is stopped. That is, in the embodiment of the present invention, part of the power in the storage unit exceeding the fourth power threshold is supplied to the power grid.

[0104] In the embodiment of the present invention, the specific value of the fourth power threshold (hereinafter represented by X) is not particularly limited, as long as the fourth power threshold can maintain the current photovoltaic charging system to charge the vehicle normally. As an optional implementation, the fourth power threshold can be "peak power theoretical reserve power".

[0105] In order to determine the "peak theoretical reserve capacity", the control method may include:

[0106] Obtain weather forecast information within a first future set time period;

[0107] Determining radiation forecast information within the first future set time period according to the acquired weather forecast information;

[0108] Determining the predicted power generation of the photovoltaic components of the current photovoltaic charging system within the first future set time period according to the irradiation prediction information;

[0109] Based on the predicted power generation within the first future set time period and the predicted power consumption of the charging device of the current photovoltaic charging system during the peak power consumption of the power grid within the second future time period.

[0110] That is to say, in the embodiment of the present invention, the weather conditions in the future set time period and the duration of the historical peak need to be considered to determine the fourth power threshold.

[0111] As an optional implementation, the fourth power threshold may be calculated using the following formula (1):

[0112] X=X2-X1+X3 (1)

[0113] Among them, X is the fourth power threshold; X1 is the predicted power generation from the peak power consumption of the power grid to the low power consumption of the power grid in the first future set time period; X2 is the estimated power consumption of the charging device from the peak power consumption of the power grid to the low power consumption of the power grid in the second future set time period; X3 is the first calculated fault tolerance value.

[0114] In the embodiment of the present invention, there is no special limitation on the calculation of the fault tolerance value, and the specific value of X3 can be determined according to the specific application scenario.

[0115] As an optional implementation, the future set time period may be one or several days in the future. In order to ensure the accuracy of the prediction result, optionally, the future set time period may be one day in the future.

[0116] After determining the theoretical reserved power during the peak power consumption period, the control method may further include:

[0117] When the remaining power of the power storage unit of the current photovoltaic charging system is higher than the theoretical reserved power and the current time period belongs to the peak power consumption of the power grid, part of the electric energy in the power storage unit that exceeds the theoretical reserved power during the peak power consumption is transmitted to the inverter of the current photovoltaic charging system, so that the inverter converts the direct current output of the power storage unit into alternating current and transmits it to the power grid.

[0118] In the field of photovoltaic power generation, if the electricity generated by the photovoltaic module cannot be stored, it can only be fed into the grid, otherwise the photovoltaic power generation cannot be effectively utilized. In the embodiment of the present invention, in order to improve the utilization rate of the photovoltaic module power generation, part of the electric energy in the storage unit that exceeds the theoretical reserved power during the peak power consumption is provided to the grid, which can not only meet the needs of vehicle charging, but also alleviate the power consumption pressure of the grid.

[0119] In the embodiment of the present invention, there is no special limitation on how to determine "the predicted power consumption of the charging device of the current photovoltaic charging system during the peak power consumption of the power grid in the second future time period". For example, the predicted power consumption of the charging device of the current photovoltaic charging system during the peak power consumption of the power grid in the second future time period can be determined based on the power consumption of the charging device during the peak power consumption of the power grid in history. For example, the predicted power consumption of the charging device of the current photovoltaic charging system during the peak power consumption of the power grid in the second future time period can be calculated based on the power consumption of the charging piles during the peak power consumption of the power grid in history in the past three months.

[0120] For example, based on the average power generation data of a specific photovoltaic module on non-rainy days, a specific photovoltaic module with a power of 700W generates about 3KW.h of electricity per day, with a power generation time of 8:00-18:00, and an average power generation power of about 300W. Taking the current charging power of a certain vehicle model of 250KW as an example, the charging device should be installed with 834 photovoltaic modules to ensure the continuous use of the charging pile.

[0121] As mentioned above, in addition to the peak power consumption of the power grid, there is also a low power consumption of the power grid. In the low power consumption, the power grid is relatively sufficient. In order to ensure that the photovoltaic charging system can meet the power demand of the charging device, optionally, the control method also includes:

[0122] In step S180, when the current time period is a low-consumption period of the power grid and the remaining power of the power storage unit is lower than a fifth power threshold, control is performed to charge the power storage unit using the power grid through the inverter, wherein the fifth power threshold is higher than the first power threshold and the fifth power threshold is related to the capacity of the power storage unit. In an embodiment of the present invention, the fifth power threshold may be referred to as a "theoretical reserve power during the low-consumption period".

[0123] That is to say, in the embodiment of the present invention, electricity can be purchased from the power grid during the off-peak hours of the power grid, and the purchased electric energy can be stored in the power storage unit.

[0124] In the embodiment of the present invention, there is no special limitation on how to realize "charging the power storage unit through the power grid". For example, a switching unit is provided at the current input end of the power storage unit, and the power storage unit can be selectively connected to the photovoltaic module and the power grid by controlling the conduction state of the switching unit. In the embodiment of the present invention, a controller can be used to control the conduction state of the switching unit.

[0125] In the embodiment of the present invention, there is no special limitation on how to calculate the fifth power threshold. Optionally, the control method may further include:

[0126] Obtain weather forecast information within a first future set time period;

[0127] Determining radiation forecast information within the first future set time period according to the acquired weather forecast information;

[0128] Determining the predicted power generation of the photovoltaic components of the current photovoltaic charging system within the first future set time period according to the irradiation prediction information;

[0129] Determine the theoretical reserve power of the power storage unit of the current photovoltaic charging system at the low power consumption valley according to the predicted power generation in the first future set time period and the predicted power consumption of the charging device of the current photovoltaic charging system in the second future time period at the low power consumption valley of the power grid;

[0130] When the remaining power of the power storage unit of the current photovoltaic charging system is lower than the theoretical reserve power during the power consumption valley and the current period belongs to the power consumption valley of the power grid, the power storage unit of the current photovoltaic charging system is charged by using the power grid.

[0131] For example, the fifth power threshold may be calculated using formula (2).

[0132] Y=Y2-Y1-Y3 (2)

[0133] Among them, Y is the fifth power threshold; Y1 is the capacity of the power storage unit; Y2 is the estimated power generation from the low point of power consumption of the power grid to the next peak point of power consumption of the power grid; and Y3 is the second calculated fault tolerance value.

[0134] In the embodiment of the present invention, there is no particular limitation on how to specifically control the charging device to charge the vehicle. As an optional implementation, the control of the photovoltaic assembly to store the generated electrical energy into the power storage unit can be specifically performed as follows:

[0135] When the power generated by the photovoltaic assembly is greater than the charging power of the vehicle, the photovoltaic assembly is controlled to store the generated electric energy in the power storage unit.

[0136] That is to say, no matter how much remaining power the current storage unit has, if the power generation power of the photovoltaic component is greater than the charging power of the vehicle, the photovoltaic component can be controlled to store the generated electrical energy into the storage unit.

[0137] When the remaining power of the power storage unit of the current photovoltaic charging unit is lower than the first power threshold, the current time period belongs to the peak power consumption of the power grid, and the power generation power of the power storage unit is not greater than the charging power of the charging device of the current photovoltaic charging unit for charging the charging device, the adjacent photovoltaic charging system is controlled to charge the power storage unit of the current photovoltaic charging system, wherein the first power threshold is not lower than the single usage power of the charging device of the photovoltaic charging system.

[0138] As an optional implementation, the control method may further include:

[0139] In step S1010, when the remaining power of the storage unit of the current photovoltaic charging system is lower than the first power threshold, the power generation power of the photovoltaic component is not greater than the charging power of the vehicle, and the remaining power of the adjacent photovoltaic charging system is greater than the third power threshold, the adjacent photovoltaic charging system is controlled to charge the storage unit of the current photovoltaic charging system.

[0140] In step S1020, when the remaining power of the storage unit of the current photovoltaic charging system is lower than the first power threshold, the power generation power of the photovoltaic component is not greater than the charging power of the vehicle, and the remaining power of the adjacent photovoltaic charging system is not greater than the third power threshold, control is performed to supply power to the charging device of the current photovoltaic charging system through the power grid.

[0141] In the embodiment of the invention, if the power generation power is greater than the charging power, the power of the adjacent power station (here, the power station is provided with a photovoltaic charging system) is preferentially dispatched to charge the power storage unit of the current photovoltaic charging unit. If the remaining power of the power storage unit of the adjacent photovoltaic charging system is insufficient and the current period is a low point in power consumption of the power grid, it is necessary to use the power grid to supply power to the power storage unit of the current photovoltaic charging unit to ensure that the required vehicles can be charged. Of course, even if the current period is a peak period in power consumption of the power grid, if the remaining power of the current photovoltaic charging system is insufficient and the power storage unit of the adjacent photovoltaic charging system is still insufficient, it is also necessary to use the power grid to supply power to the power storage unit of the current photovoltaic charging unit to ensure that the required vehicles can be charged.

[0142] As an optional implementation, the first sensing signal is a signal emitted by a grating sensor.

[0143] As an optional implementation, the second sensing signal is a signal sent by a gravity sensor.

[0144] Optionally, the control method further includes:

[0145] The site information of the current photovoltaic charging system is sent to the network-side server, wherein the site information at least includes the location identification information of the current photovoltaic charging system and the remaining power information of the current photovoltaic charging system.

[0146] Accordingly, the user can query the nearby photovoltaic charging system and the remaining power information of the nearby photovoltaic charging system through a terminal device (e.g., a mobile phone, a vehicle's center console), and send a reservation charging request to the photovoltaic charging system that can provide charging services. The reservation charging request may carry the vehicle information of the vehicle to be charged.

[0147] After receiving the scheduled charging status, the controller of the photovoltaic charging system can reserve power according to the vehicle information of the vehicle to be charged.

The main body shell 700 has an entrance and exit for vehicles to enter and exit, the charging device is arranged in the main body shell, and the set charging position and the set storage position are both located in the main body shell 700.

[0155] In the embodiment of the present invention, there is no particular limitation on the specific type of the charging device 200, as long as it can charge the vehicle. For example, the charging device 200 may be a charging pile.

[0156] The photovoltaic charging system further includes a controller 300, a sensing module, a vehicle transfer platform 600 and a platform driving device 500. Figure 8 As shown, the sensing module and the platform driving device 500 are both electrically connected to the controller 300 , and the platform driving device 500 is electrically connected to the vehicle transfer platform 600 .

[0157] The sensing module is used to send a first sensing signal to the controller when a vehicle is detected at the vehicle handover position, and the sensing module is also used to send a second sensing signal to the controller when a vehicle is detected to leave the vehicle transfer platform. Specifically, as an optional embodiment, the sensing module includes a first sensor 810 disposed at the main body shell 700 and a second sensor 820 disposed at the vehicle transfer platform.

[0158] The first sensor 810 is disposed on the main body shell 700 , and the first sensor 810 is used to detect whether there is a vehicle at the vehicle handover position, and to generate the first sensing signal when there is a vehicle at the vehicle handover position.

[0160] It should be noted that the controller 300 is the controller provided by the second aspect of the present invention.

[0161] As described above, the photovoltaic charging system provided in the embodiment of the present invention is arranged on one side of the road. When there is no vehicle to be charged, the vehicle transfer platform 600 is in a storage position away from the road to avoid affecting the road traffic.

[0162] When the vehicle needs to be charged, the driver drives the vehicle to the vehicle handover position near the photovoltaic charging system. After the sensing module detects the vehicle, it generates the first sensing signal and sends it to the controller 300. As described above, the controller 300 sends a first control signal to the platform drive device 500 in response to the first sensing signal. After receiving the first control signal, the platform drive device 500 drives the vehicle transfer platform 600 to move to the vehicle handover position. The driver drives the vehicle to the vehicle transfer platform 600 located at the vehicle handover position, and the vehicle transfer platform 600 transfers the vehicle to the set charging position, so that the vehicle is charged using the charging device set at the set charging position.

[0163] After charging is completed, the controller 300 sends a second control signal to the platform driving device 500, and the platform driving device 500 drives the vehicle transfer platform 600 to move the vehicle to the vehicle handover position according to the second control signal.

[0164] After the vehicle arrives at the vehicle handover position, the driver drives the vehicle away from the vehicle transfer platform 600. In this case, the sensing module generates a second sensing signal. After receiving the second sensing signal, the controller 300 sends a third control signal to the platform driving device 500, and finally uses the platform driving device 600 to drive the vehicle transfer platform 600 back to the set storage position away from the road.
