[0002] There is known a driving control device for an autonomous vehicle equipped with a solar cell panel. In this driving control device, even if the power consumption during round trip between the autonomous vehicle's current position and the solar power generation site is taken into account, the autonomous vehicle is driven to the solar power generation site by autonomous driving if the predicted charge amount of the battery when charged by solar power generation at the solar power generation site is greater than the predicted charge amount of the battery when charged by solar power generation at the current position (for example, refer to International Publication No. 2016-072165).

[0003] However, this driving control device has the following problem: it does not detect in advance whether the parking space of the autonomous vehicle at the solar power plant actually has good sunlight. Therefore, even if the autonomous vehicle moves to the solar power plant, it is unclear whether the battery can be fully charged. Summary of the Invention

[0019] Figure 1A is a top view schematically showing an automatic parking lot. Figure 1B yes Figure 1A Side view of the automatic parking lot shown. Figure 1A and Figure 1B , 1 represents a facility such as a department store, 2 represents an automatic parking lot adjacent to facility 1, 3 represents a boarding and alighting location, and 4 represents an autonomous vehicle parked at boarding and alighting location 3. Figure 1A As shown, a plurality of parking spaces P are provided in the automatic parking lot 2. In the automatic parking lot 2, an automatic parking service, namely, an automatic valet parking service, is implemented, which enables an automatic driving vehicle 4 arriving at a boarding and disembarking area 3 to enter an empty parking space P by automatic driving, and enables an automatic driving vehicle parked in a parking space P to leave the parking space P by automatic driving. Figure 1AIn FIG, 5 represents a parking management server disposed in the parking management facility. It should be noted that the automatic parking lot 2 can also be used for parking manually driven vehicles.

[0020] When a user utilizing this automated parking service parks their vehicle in an automated parking lot 2, for example, when their autonomously driving vehicle arrives at a pick-up / drop-off location 3, they transmit a parking entry request, along with their vehicle ID, to a parking management server 5 via a communications network. Upon receiving the parking entry request, the parking management server 5 sets a driving route that allows the vehicle to reach an available parking space P from the pick-up / drop-off location 3 without contact with other vehicles or pedestrians, and transmits this set driving route to the user's vehicle. Upon receiving the set driving route from the parking management server 5, the user's vehicle automatically moves along the set driving route from the pick-up / drop-off location 3 to an available parking space P.

[0021] The same process also applies when a user unloads their vehicle from the automated parking lot 2. For example, when the user arrives at the boarding / dropping-off location 3, they transmit a request for unloading from their mobile terminal to the parking management server 5 via the communication network, along with their vehicle ID, identifying the vehicle. Upon receiving the unloading request, the parking management server 5 sets a driving route that allows the vehicle to reach the boarding / dropping-off location 3 from the currently parked parking space P without contact with other vehicles or pedestrians, and transmits this set driving route to the user's vehicle. Upon receiving the set driving route from the parking management server 5, the user's vehicle automatically moves along this set driving route from the currently parked parking space P to the boarding / dropping-off location 3.

[0022] Next, if Figure 1A As shown, in the automatic parking lot 2, a plurality of infrastructure sensors 6 are provided so as to be able to detect the state of the entire area within the automatic parking lot 2. Figure 1B As shown, these infrastructure sensors 6 are installed at a higher position than the vehicle. Cameras, laser sensors, and the like can be used as these infrastructure sensors 6. The following description uses a camera as an example. Specifically, the description uses the example of infrastructure sensors 6 capturing images of the interior of the automated parking lot 2. In this case, each infrastructure sensor 6 captures images of all parking spaces P and all pathways between parking spaces P within the automated parking lot 2. The image signals captured by each infrastructure sensor 6 are transmitted to the parking management server 5. The parking management server 5 uses these image signals to set the driving route of the automated vehicle during entry and exit.

[0023] Figure 2 Shown Figure 1A Parking management server 5. Figure 2As shown, an electronic control unit 10 is provided in the parking management server 5. The electronic control unit 10 is composed of a digital computer and includes a CPU (microprocessor) 12, a memory 13 composed of ROM and RAM, and an input / output port 14, which are interconnected via a bidirectional bus 11. Figure 2 As shown, image signals captured by the infrastructure sensors 6 are input to the electronic control unit 10. In addition, map data of the automatic parking lot 2 is stored in the memory 13 of the electronic control unit 10.

[0024] Figure 3 An example of an autonomous vehicle 20 with solar power generation capability is shown diagrammatically. Figure 3 , 21 denotes a vehicle drive unit for applying driving force to the drive wheels of the vehicle 20, 22 denotes a battery for supplying power to the vehicle drive unit 21, 23 denotes a solar cell panel provided on the roof of the vehicle 20, 24 denotes a charge control device for charging the battery 22 with power generated by the solar cell panel 23, 25 denotes a braking device for braking the vehicle 20, 26 denotes a steering device for steering the vehicle 20, and 27 denotes an electronic control unit mounted in the vehicle 20. Figure 3 As shown, the electronic control unit 27 is constituted by a digital computer and includes a CPU (microprocessor) 29 , a memory 30 constituted by a ROM and a RAM, and an input / output port 31 , which are interconnected via a bidirectional bus 28 .

[0025] On the other hand, Figure 3 As shown, the vehicle 20 is equipped with various sensors 40 necessary for autonomous driving, namely sensors that detect the state of the vehicle 20 and perimeter sensors that detect the surroundings of the vehicle 20. In this case, sensors that detect the state of the vehicle 20 include acceleration sensors, speed sensors, and azimuth sensors. Sensors that detect the perimeter of the vehicle 20 include onboard cameras that capture images of the front, sides, and rear of the vehicle 20, laser radar (LIDAR), and radar. Furthermore, the vehicle 20 is equipped with a GNSS (Global Navigation Satellite System) receiver 41, a map data storage device 42, a navigation device 43, and an operating unit 44 for performing various operations. The GNSS receiver 41 can detect the current position of the vehicle 20 (e.g., the latitude and longitude of the vehicle 20) based on information obtained from multiple artificial satellites. Therefore, the current position of the vehicle 20 can be acquired through the GNSS receiver 41. For example, a GPS receiver can be used as the GNSS receiver 41.

[0026] On the other hand, the map data storage device 42 stores map data and the like required for the vehicle 20 to perform autonomous driving. The various sensors 40, the GNSS receiving device 41, the map data storage device 42, the navigation device 43, and the operation unit 44 are connected to the electronic control unit 27. In addition, the vehicle 20 is equipped with a communication device 45 for communicating with the parking management server 5. Figure 2 As shown in FIG. 1 , a communication device 15 for communicating with the vehicle 20 is provided in the parking management server 5 . Figure 3 In the illustrated example, the vehicle drive unit 21 is comprised of an electric motor driven by a battery 22. The drive wheels of the vehicle 20 are driven and controlled by the electric motor in accordance with an output signal from an electronic control unit 27. Furthermore, the braking of the vehicle 20 is controlled by a braking device 25 in accordance with an output signal from the electronic control unit 27, and the steering of the vehicle 20 is controlled by a steering device 26 in accordance with an output signal from the electronic control unit 27.

[0027] To efficiently generate solar power using solar panels 23 while autonomous vehicle 20 is parked in automated parking lot 2, vehicle 20 must be parked in a sunlit parking space P. Therefore, it is necessary to determine which parking spaces P are actually illuminated by sunlight. In this case, images captured by infrastructure sensors 6 can be used to identify sunlit and non-sunlit areas within all parking spaces P and all pathways between parking spaces P within automated parking lot 2. Therefore, in this embodiment of the present invention, to ensure that vehicle 20 is parked in a sunlit parking space P, the sunlit areas are determined based on images captured by infrastructure sensors 6.

[0028] Next, refer to Figure 1A 、 Figure 4 as well as Figure 5 , and based on a specific example, the outline of the present invention is described. First, refer to Figure 1A ,exist Figure 1A In the figure, the area X surrounded by the dotted line (with hatching only around the area) represents the shaded area created by facility 1 at noon on a particular day, and the area Y surrounded by the dashed line (with hatching only around a portion of the area) represents the shaded area created by facility 1 at dusk on the same day. Thus, the positions of shaded areas X and Y vary throughout the day and also vary with the seasons, such as spring, summer, autumn, and winter. Furthermore, if structures that block sunlight are installed within or around automated parking lot 2, the shaded area will also change. Therefore, it is impossible to determine the area of ​​sunlight within automated parking lot 2 based solely on the weather.

[0029] Therefore, in the embodiment according to the present invention, the area illuminated by sunlight is determined based on the images captured by each infrastructure sensor 6. In this case, if the proportion of the area illuminated by sunlight in each parking space P is referred to as the sunlight intensity R, then in the embodiment according to the present invention, the sunlight intensity R of each parking space P is calculated based on the images captured by each infrastructure sensor 6. Figure 4 Shown Figure 1A The parking spaces P shown are representative parking spaces P1, P2, and P n 、P m The change in sunshine intensity R from 6:00 to 18:00 on a certain day, Figure 5 The representative parking spaces P1, P2, and P3 are shown for a portion of the time period from 6:00 to 18:00 on the same day. n 、P m A table showing the changes in the sunshine intensity R at Figure 5 In the example shown, changes in solar irradiance R every 10 minutes are shown.

[0030] Next, refer to Figure 6 The calculation method of the solar illuminance R will be described. Figure 6 FIG. 2 shows a routine for calculating the solar illuminance R, which is repeatedly executed in the electronic control unit 10 of the parking management server 5. Figure 6 First, in step 50, it is determined whether it is the calculation time of the sunshine intensity R. In the embodiment according to the present invention, Figure 5 As shown, the sunshine intensity R is calculated every 10 minutes. For example, time 6:00, time 6:10, and time 6:20 are set as the calculation time of sunshine intensity R. If it is determined in step 50 that it is not the calculation time of sunshine intensity R, the processing loop ends. If it is determined that it is the calculation time of sunshine intensity R, the process proceeds to step 51.

[0031] In step 51, detection signals, i.e., image signals, are acquired from each infrastructure sensor 6. Next, in step 52, based on these image signals, it is determined whether sunlit and shaded areas can be identified. For example, on sunny days, sunlit and shaded areas can be identified, while on cloudy days, when there is no sunlight, sunlit and shaded areas cannot be identified. If it is determined that sunlit and shaded areas cannot be identified in step 52, the processing loop ends. If it is determined that sunlit and shaded areas can be identified, the process proceeds to step 53.

[0032] In step 53, based on the map data of the automatic parking lot 2 stored in the memory 13 of the electronic control unit 10 of the parking management server 5, the image signals of each infrastructure sensor 6 are obtained to determine the location of the parking lot 2. Figure 1AThe sunlit area on the plan view of the automatic parking lot 21 as shown is used to calculate the solar radiation R of each parking space P based on the determined sunlit area and the position of each parking space P. When the solar radiation R is calculated, the process proceeds to step 54 to update the solar radiation R of each parking space P stored in the memory 13 of the electronic control unit 10 of the parking management server 5. Thus, in the case where the sunlit area and the shaded area can be identified, the current actual solar radiation R of each parking space P is stored in the memory 13, and in the case where the sunlit area and the shaded area cannot be identified, the solar radiation R of each parking space P updated last time, i.e., the latest actual solar radiation R of each parking space P, is stored in the memory 13.

[0033] Figure 7 An information providing routine for providing information related to the solar radiation R is shown, which is repeatedly executed in the electronic control unit 10 of the parking management server 5.

[0034] Referring to Figure 7 First, in step 60, the solar radiation R of each parking space P stored in the memory 13 is read. Next, in step 61, the solar radiation R of each parking space P is notified to the vehicle 20 having the solar power generation function or the user of the automatic parking lot 2, etc., who needs to acquire information related to the solar radiation R of each parking space P. In this case, there are various methods for notifying the information related to the solar radiation R of each parking space P. For example, it can be configured to enable the information related to the solar radiation R of each parking space P to be viewed when the parking management server 5 is accessed, or the information related to the solar radiation R of each parking space P can be notified to the object who needs to acquire the information from the parking management server 5 via a communication network.

[0035] Thus, in the embodiment according to the present application, there are provided the infrastructure sensor 6 capable of detecting the sunlit state of each parking space P in the parking lot 2, and the notification device for notifying the sunlit state of each parking space P detected by the infrastructure sensor 6 to at least one of the vehicle 20 having the solar power generation function and the user of the parking lot 2. In this case, in the embodiment according to the present application, the parking management server 5 constitutes the notification device.

[0036] Furthermore, in an embodiment according to the present invention, the sunlight conditions of each parking space P at regular intervals are notified to at least one of the vehicle 20 with solar power generation capabilities and the user of the parking lot 2. Furthermore, in an embodiment according to the present invention, when the current actual sunlight conditions of the parking spaces P in the parking lot 2 can be detected by the infrastructure sensor 6, the current actual sunlight conditions of the parking spaces P in the parking lot 2 are notified to at least one of the vehicle 20 with solar power generation capabilities and the user of the parking lot 2. When the current actual sunlight conditions of the parking spaces P in the parking lot 2 cannot be detected by the infrastructure sensor 6, the latest actual sunlight conditions of the parking spaces P are notified to at least one of the vehicle 20 with solar power generation capabilities and the user of the parking lot 2.

[0037] In addition, in an embodiment of the present invention, based on the sunlight conditions of each parking space P detected by the infrastructure sensor 6, the sunlight intensity R is calculated for each parking space P, and the sunlight intensity R is notified to at least one of the vehicle 20 with solar power generation function and the user of the parking lot 2.

[0038] Moreover, according to an embodiment of the present invention, a parking lot management method is provided, which uses an infrastructure sensor 6 that can detect the sunlight status of the parking spaces P in the parking lot 2, and notifies at least one of the vehicle 20 with solar power generation function and the user of the parking lot 2 of the sunlight status of each parking space P detected by the infrastructure sensor 6.

[0039] Furthermore, according to an embodiment of the present invention, a program is provided that causes a computer to function as follows: using infrastructure sensor 6 capable of detecting the sunlight conditions of parking spaces P within parking lot 2, the program notifies at least one of a vehicle 20 equipped with a solar power generation function and a user of parking lot 2 of the sunlight conditions of each parking space P detected by infrastructure sensor 6. The program is stored in a storage medium.

[0040] Next, a method for entering and exiting a parking space in an automatic parking lot 2 will be described, which is applied when a user of the automatic parking service parks the automatic parking lot 20 in the automatic parking lot 2 so that the automatic parking lot 20 generates solar power through the solar cell panel 23 while the automatic parking lot 20 is parked in the automatic parking lot 2. Figure 8 A parking management routine for carrying out a parking method for parking in and out of the automatic parking lot 2 is shown. This routine is repeatedly executed in the electronic control unit 10 of the parking management server 5 .

[0041] Reference Figure 8First, in step 70, it is determined whether there is a request to enter the automatic parking lot 2. If it is determined that there is a request to enter the automatic parking lot 2, the process proceeds to step 71 to determine whether there is a request to generate solar power using the solar cell panel 23 while the vehicle is parked. If it is determined that there is no request to generate solar power using the solar cell panel 23, the process ends. On the other hand, if it is determined that there is a request to generate solar power using the solar cell panel 23, the process proceeds to step 72 to obtain the vehicle ID of the autonomous driving vehicle 20. It should be noted that when a request to enter the automatic parking lot 2 is made, a request is made to register a scheduled exit time, and in step 73, the registered scheduled exit time is obtained. Next, in step 74, a moving time is set for moving to the parking space of the autonomous driving vehicle 20 before the scheduled exit time. This moving time is set, for example, 30 minutes before the scheduled exit time.

[0042] Next, in step 75, based on Figure 5 The list shown in FIG. 1 is used to search for vacant parking spaces P with high sunlight R between the time of entry and the time of movement. Preferably, a vacant parking space P with 100% sunlight R is searched for, and the vacant parking space P with high sunlight R is set as the movement destination. Next, in step 76, a driving route from the boarding and disembarking area 3 to the set movement destination is set based on the map data of the automated parking lot 2 stored in memory 13. Next, in step 77, the driving trajectory and speed of the automated parking lot 20 are determined based on the map data of the automated parking lot 2 stored in memory 13 and the image signals from the infrastructure sensors 6, so as to avoid contact with other vehicles or pedestrians.

[0043] In this case, when the autonomous vehicle 20 arrives at its destination and parks in the designated parking space P, the autonomous vehicle 20's travel trajectory and speed can be determined, including the parking posture of the autonomous vehicle 20 relative to the designated parking space P, so that sunlight shines more intensely on the rear side of the autonomous vehicle 20 than on the front side. This has the advantage of preventing yellowing of the headlights and heating of the drive recorder by parking the vehicle 20 more intensely than on the front side. Next, in step 78, an autonomous driving execution command is issued for the autonomous vehicle 20. Then, in step 79, the parking management server 5 transmits the designated destination, travel route, travel trajectory, travel speed, and autonomous driving execution command to the autonomous vehicle 20.

[0044] When an automatic driving execution instruction is transmitted from the parking management server 5 to the automatic driving vehicle 20 , automatic driving control of the automatic driving vehicle 20 is started. Figure 9 An automatic driving control routine for performing automatic driving control of the automatic driving vehicle 20 is shown. This routine is repeatedly executed in the electronic control unit 27 mounted on the vehicle 20 .

[0045] Reference Figure 9 First, in step 90, the destination set in the parking management server 5 is obtained. Next, in step 91, the driving route set in the parking management server 5 is obtained. In step 92, the driving trajectory and driving speed set in the parking management server 5 are obtained. Next, in step 93, the autonomous vehicle 20 is controlled along the set driving trajectory based on the detection results of cameras, LIDAR, radar, etc., which capture the front of the autonomous vehicle 20, in a manner that avoids contact with other vehicles or pedestrians. Next, in step 94, it is determined whether the autonomous vehicle 20 has reached the destination. If it is determined that the autonomous vehicle 20 has not reached the destination, the process returns to step 93 and the autonomous driving of the autonomous vehicle 20 continues. On the other hand, if it is determined that the autonomous vehicle 20 has reached the destination in step 94, the process proceeds to step 95 and the autonomous driving control of the autonomous vehicle 20 ends.

[0046] Return to Figure 8 In step 70, when it is determined that no entry request to the automatic parking lot 2 has been issued, the process proceeds to step 80 to determine whether the current time has become the moving time set in step 74. If it is determined that the current time has not become the moving time set in step 74, the process loop ends. On the other hand, if it is determined that the current time has become the moving time set in step 74, the process proceeds to step 81. Figure 5 The list shown in FIG. 1 retrieves an idle parking space P with low sunlight R from the current time to the scheduled time of departure, preferably retrieves an idle parking space P that is in the shade, and sets an idle parking space P with low sunlight R as a new moving destination from the current time to the scheduled time of departure, preferably sets an idle parking space P that is in the shade as a new moving destination.

[0047] Next, in step 82, a driving route from the current parking space P3 to the set new moving destination is set based on the map data of the automatic parking lot 2 stored in the memory 13. Next, in step 83, the driving trajectory and driving speed of the automatic driving vehicle 20 that does not come into contact with other vehicles or pedestrians are determined based on the map data of the automatic parking lot 2 stored in the memory 13 and the image signal of the infrastructure sensor 6. Next, in step 78, an automatic driving execution instruction of the automatic driving vehicle 20 is issued, and then, in step 79, the set new moving destination, driving route, driving trajectory, driving speed and automatic driving execution instruction are sent from the parking management server 5 to the automatic driving vehicle 20. When the automatic driving execution instruction is sent from the parking management server 5 to the automatic driving vehicle 20, the execution Figure 9 The automatic driving control routine shown performs automatic driving of the automatic driving vehicle 20 until it reaches a set new destination.

[0048] So, in Figure 8 and Figure 9 In the embodiment shown, based on the sunlight conditions of each parking space P detected by the infrastructure sensor 6, parking spaces P with high sunlight R and parking spaces P with low sunlight R are identified. When there is a parking request from the autonomous driving vehicle 20 with solar power generation function, the autonomous driving vehicle 20 is moved to the parking space P with high sunlight R by autonomous driving to park. In this case, Figure 8 and Figure 9 In the illustrated embodiment, the autonomous driving vehicle 20 parked in a parking space P with high sunlight R is moved to a parking space P with low sunlight R, preferably a shaded parking space P, before a scheduled exit time.

[0049] In this manner, the autonomous vehicle 20 parked in a parking space P with high sunlight intensity R is moved to a parking space P with low sunlight intensity R, preferably to a shady parking space P, before the scheduled departure time. This allows the indoor temperature of the autonomous vehicle 20 to be lowered before the autonomous vehicle 20 leaves the parking space. Note that in this case, the time interval between the moving time and the scheduled departure time can be adjusted based on the indoor temperature of the parked autonomous vehicle 20 or the position of the sun, so that the indoor temperature of the autonomous vehicle 20 can be sufficiently lowered before the autonomous vehicle 20 leaves the parking space.
