This application is based on and claims the benefit of priority from earlier Japanese Patent Application No. 2017-232295 filed on Dec. 4, 2017, the description of which is incorporated herein by reference.
The present disclosure relates to a parking assistance control apparatus.
A parking assistance control apparatus disclosed in Japanese Patent No. 5365349 is configured to learn parking locations during manual parking of a vehicle by a driver, and use the learned parking locations during automatic parking of the vehicle, thereby achieving automatic parking according to driver preferences.
A motor-drivable vehicle, such as an electrical vehicle, a plug-in hybrid vehicle or the like, includes a rechargeable battery to power a motor of the vehicle. In such a vehicle, electrical connection between electrical supply equipment installed in a parking lot and a charging port of the vehicle via a charging cable enables power supply to the battery.
In general, a mounting location of the charging port may vary from vehicle to vehicle. Thus, depending on a parking location at completion of automatic parking of the vehicle conducted by the parking assistance apparatus, a length of the charging cable may be too short to connect the charging port of the vehicle and the electrical supply equipment. In such a case, an occupant of the vehicle may be forced to re-park the vehicle to get the charging port of the vehicle closer to the electrical supply equipment. In addition, in the case of a vehicle that can be automatically driven, there may be assumed a situation where a person having no driving skill or no driving license operates a vehicle. In such a situation, the person is not able to properly move the vehicle, which may make it difficult to charge the battery.
A vehicle that is only be manually driven, but has a function of assisting a driver with driving the vehicle by displaying parking assistance information on a display or audibly outputting the parking assistance information from a speaker may also encounter a similar issue.
In view of the above, it is desired to have a parking assistance control apparatus that can prevent a situation where an occupant is forced to re-park a vehicle.
One aspect of the disclosure provides a parking assistance control apparatus for assisting parking a vehicle including a charging port that is connectable to electrical supply equipment via a charging cable. The parking assistance control apparatus includes: a charging port recognizer configured to recognize a mounting location of the charging port on the vehicle; an electrical supply equipment recognizer configured to recognize an installation location of the electrical supply equipment; and a parking assistance controller configured to, based on the mounting location of the charging port on the vehicle and the installation location of the electrical supply equipment, determine a parking manner to park the vehicle, and based on the determined parking manner, perform parking assistance control.
This configuration enables parking the vehicle in an optimal parking direction responsive to locations of the charging port on the vehicle and the electrical supply equipment, which can prevent a situation where the vehicle must be reparked.
In the following, exemplary embodiments will be described with reference to the accompanying drawings. For easy understanding of the description, the same components are designated with the same reference signs as much as possible in the drawings, and duplicate description will be omitted.
A schematic of a vehicle 20 carrying a parking assistance apparatus 10 in accordance with a first embodiment of the present disclosure will now be described with reference to
The vehicle 20 may be a motor-drivable vehicle, such as an electrical vehicle, a plug-in hybrid vehicle or the like, including a rechargeable battery to power a motor of the vehicle. The vehicle 20 includes a battery 22 used to power the motor 21 and an inverter 23 that convers direct-current (DC) power supplied form the battery 22 into alternating-current (AC) power to power the motor 21. The motor 21 is driven by the AC power supplied from the inverter 23 to the motor 21. The vehicle 20 is provided with a charging port 24 that allows for connection to and disconnection from a charging cable 31 for electrical supply equipment 30 and a charging port 25 that allows for connection to and disconnection from a charging cable 61 for a commercially available AC outlet 60. The charging cables 31, 61 are carried by the vehicle 20. In an alternative embodiment, the charging cable 31 may be attached to the electrical supply equipment 30.
To perform normal charging of a battery 22 in the vehicle 20, the charging port 25 on the vehicle 20 is connected to the commercially available AC outlet 60 via the charging cable 61. The vehicle 20 is supplied with alternating-current (AC) power of 100 to 200 volts from the commercially available AC outlet 60. This AC power is converted into direct-current (DC) power by the vehicle-mounted charger 26. The DC power is in turn supplied to the battery 22, thereby charging the battery 22.
To perform rapid charging of the battery 22 in the vehicle 20, the charging port 24 on the vehicle 20 is connected to the electrical supply equipment 30 via the charging cable 31, thereby initiating a supply of power from the electrical supply equipment 30 to the vehicle 20. In an alternative embodiment, a supply of power from the electrical supply equipment 30 to the vehicle 20 may be initiated when the electrical supply equipment 30 undergoes predefined operations after the charging port 24 on the vehicle 20 has been connected to the electrical supply equipment 30 via the charging cable 31. The electrical supply equipment 30 performs voltage adjustment and of conversion and then supplies power to the vehicle 20. Supplying the DC power to the battery 22 via the charging port 24 enables charging the battery 22.
The parking assistance apparatus 10 mounted on the vehicle 20 includes an imager 11, an image processing electronic control unit (ECU) 12, a console 13, and a short-range communication unit 14, and a parking assistance ECU 15.
The imager 11 captures an image of surroundings around the vehicle 20 every predetermined time interval to acquire image data of the surroundings of the vehicle. The imager 11 transmits the image data to the image processing ECU 12 every predetermined time interval.
The image processing ECU 12 may be configured as a microcomputer including a central processing unit (CPU), a random-access memory (RAM), a read-only memory (ROM), and a non-volatile memory (e.g., EEPROM). The image processing ECU 12 performs various types of processing on image data received from the imager 11 by executing programs pre-stored in the ROM. For example, the image processing ECU 12 processes the image data to acquire location information for the parking slot and the electrical supply equipment 30 included in the image data.
The console 13 can be operated by an occupant of the vehicle 20. The console 13 includes push buttons to be operated when automatically parking the vehicle 20. The console 13 transmits operation signals responsive to vehicle occupant operations to the parking assistance ECU 15.
The short range communication unit 14 is configured to receive a recognition signal transmitted from the electrical supply equipment 30 and the like. The recognition signal may include only information indicating that an originator of the recognition signal is the electrical supply equipment 30 or may include not only information indicating that an originator of the recognition signal is the electrical supply equipment 30, but also location information indicating a location of the electrical supply equipment 30 relative to a parking slot. For example, assuming that, as shown in
The parking assistance ECU 15 is configured as a microcomputer including a central processing unit (CPU) and a read-only memory (ROM), a random-access memory (RAM), and a nonvolatile memory. The parking assistance ECU 15 performs automatic parking control for automatically parking the vehicle 20 by the CPU executing programs pre-stored in the ROM. In the present embodiment, this automatic parking control corresponds to parking assistance control for assisting a driver with parking the vehicle 20. The parking assistance ECU 15 corresponds to a parking assistance control apparatus. The parking assistance ECU 15 includes a charging port recognizer 150 configured to recognize a mounting location of the charging port 24 on the vehicle 20, an electrical supply equipment recognizer 151 configured to recognize an installation location of the electrical supply equipment 30, and a parking assistance controller 152 configured to perform automatic parking control based on the mounting location of the charging port 24 recognized by the charging port recognizer 150 and the location of the electrical supply equipment 30 recognized by the electrical supply equipment recognizer 151.
Automatic parking control processing performed by the parking assistance ECU 15 will now be described with reference to operations on the console 13 to initiate automatic parking in response to an operation signal transmitted from the console 13.
As shown in
At step S11 subsequent to step S10, the electrical supply equipment recognizer 151 recognizes an installation location of the electrical supply equipment 30. More specifically, the electrical supply equipment recognizer 151 receives, via the short range communication unit 14, a recognition signal transmitted from the electrical supply equipment 30, and based on this recognition signal, recognizes an installation location of the electrical supply equipment 30.
For example, in a case where the recognition signal may include only information indicating that an originator of the recognition signal is the electrical supply equipment 30, the electrical supply equipment recognizer 151 can detect a relative distance and a relative location of the electrical supply equipment 30 based on a transmission direction of the recognition signal. In this case, the electrical supply equipment recognizer 151 fuses information on the relative distance and the relative location of the electrical supply equipment 30 relative to the vehicle 20 and parking slot information that can be acquired from the image processing ECU 12, thereby recognizing an installation location of the electrical supply equipment 30 relative to the parking slot F as shown in
In another case where the recognition signal includes not only information indicating that an originator of the recognition signal is the electrical supply equipment 30, but also location information indicating a location of the electrical supply equipment 30 relative to a parking slot, the electrical supply equipment recognizer 151 recognizes an installation location of the electrical supply equipment 30 relative to the parking slot F as shown in
At step S12 subsequent to step S11, the parking assistance controller 152 determines a parking direction for the vehicle 20, that is, whether to forward park or reverse park the vehicle 20. In the present embodiment, this parking direction for the vehicle 20 corresponds to a parking manner of the vehicle 20.
More specifically, maps as shown in
For example, in a case where the charging port 24 is mounted at a forward location of the vehicle 20 and the electrical supply equipment 30 is installed at the left end of the distal side F2 of the parking slot F as shown in
According to the maps shown in
As shown in
At step S14 subsequent to step S13, the parking assistance controller 152 performs cruise control to guide the vehicle 20 to the target parking location set at step S13. More specifically, as shown in
The present embodiment can provide the following advantage.
(A1) The parking assistance controller 152 is configured to, based on a mounting location of the charging port 24 on the vehicle 20 and an installation location of the electrical supply equipment 30, determine a parking manner of the vehicle 20, more specifically, a parking direction for the vehicle 20, that is, whether to forward park or reverse park the vehicle 20, and based on the parking direction for the vehicle 20, perform parking assistance control to assist parking of the vehicle 20. The parking assistance controller 152 determines whether to forward park or reverse park the vehicle 20 as a parking direction, enabling parking the vehicle in an optimal parking direction responsive to the locations of the charging port 24 and the electrical supply equipment 30. This configuration can obviate a situation where the charging cable 31 is too short to reach the charging port 24 at completion of parking of the vehicle 20, thus causing the vehicle to be reparked. In addition, this configuration can reduce a length of the charging cable 31, thereby reducing the amount of copper cables and losses in the charging cable 31.
A second embodiment will now be described. Only differences of the second embodiment from the first embodiment will be described.
The parking assistance apparatus 10 of the present embodiment is configured to normally reverse park the vehicle 20 during automatic parking control, and if a length of the charging cable 31 is too short to reverse park the vehicle 20, then forward park the vehicle 20.
More specifically, at step S12 shown in
As shown in
If at step S101 it is determined that the distance L10 is equal to or less than the distance threshold Lth10, the parking assistance controller 152 determines that the charging cable 31 can reach the charging port 24 during reverse parking of the vehicle 20 and determines to reverse park the vehicle 20 at step S102. If at step S101 it is determined that the distance L10 is greater than the distance threshold Lth10, the parking assistance controller 152 determines that the charging cable 31 cannot reach the charging port 24 during reverse parking of the vehicle 20 and determines to forward park the vehicle 20 at step S103.
When comparing the distance L10 and the distance threshold Lth10, the distance L10 may be corrected taking into account routing of the charging cable 31. More specifically, the distance L10 may be multiplied by a predetermined value, or a predetermined value may be added to the distance L10.
The present embodiment can provide the following advantage in addition to the advantage of the first embodiment.
(A2) The parking assistance controller 152 is configured to, based on a location of the charging port 24 at completion of parking of the vehicle 20, an installation location of the electrical supply equipment 30, and a length of the charging cable 31, determine a parking direction for the vehicle 20. More specifically, the parking assistance controller 152 has a distance threshold Lth10 that is set based on the length of the charging cable 31. The parking assistance controller 152 determines a parking direction for the vehicle 20 during automatic parking control, based on whether or not the distance L10 between an estimated location of the charging port 24 at completion of reverse parking of the vehicle 20 and the location of the electrical supply equipment 30 is equal to or less than the distance threshold Lth10. With this configuration, a more proper parking direction for the vehicle 20 can be determined taking into account the length of the charging cable 31. Therefore, this configuration can more reliably obviate a situation where the charging cable 31 is too short to reach the charging port 24 on the vehicle 20 at completion of parking of the vehicle 20 and thus the battery 22 cannot be charged. In addition, this configuration can reduce the length of the charging cable 31, thereby reducing the amount of copper cables and losses in the charging cable 31.
A first modification to the second embodiment will now be described.
The parking assistance apparatus 10 of the first modification is configured such that whether to forward park or reverse park the vehicle 20 can be arbitrary set by an occupant of the vehicle 20 operating the console 13. In this configuration of the parking assistance apparatus 10, the vehicle 20 is normally to be parked in a parking direction set by the occupant. If the charging cable 31 is too short to reach the charging port 24 at completion of parking of the vehicle 20 in the parking direction set by the occupant, the vehicle 20 is to be parked in a parking direction opposite to the parking direction set by the occupant.
More specifically, at step S12 shown in
If at step S111 it is determined that the distance L11 is equal to or less than the distance threshold Lth10, the parking assistance controller 152 determines that the charging cable 31 can reach the charging port 24 during parking of the vehicle 20 in the direction set by the occupant, and at step S112, determines to park the vehicle 20 in the parking direction set by the occupant. If at step S111 it is determined that the distance L11 is greater than the distance threshold Lth10, the parking assistance controller 152 determines that the charging cable 31 cannot reach the charging port 24 during parking of the vehicle 20 in the direction set by the occupant, and at step S113, determines to park the vehicle 20 in a direction opposite to the direction set by the occupant. In such a case, the parking assistance controller 152 may provide to the occupant of the vehicle 20 a notification that the vehicle 20 is to be parked in in a direction opposite to the direction set by the occupant, via a notification unit 17 as indicated by a dashed line in
With this configuration, the vehicle 20 can be parked preferentially in a direction set by the occupant, which can improve convenience.
A second modification to the second embodiment will now be described.
The parking assistance controller 152, at step S12 shown in
If at step S121 it is determined that the distance L13 is equal to or less than the distance threshold Lth10, then at step S123 the parking assistance controller 152 estimates a distance L12 between the charging port 24 on the vehicle 20 and the electrical supply equipment 30 assuming that reverse parking of the vehicle 20 has been completed. At step S124 subsequent to step S123, the parking assistance controller 152 determines whether or not the distance L12 is greater than the distance threshold Lth10. If at step S124 it is determined that the distance L12 is greater than the distance threshold Lth10, the parking assistance controller 152 determines that the charging cable 31 cannot reach the charging port 24 during reverse parking of the vehicle 20. In this case, at step S125, the parking assistance controller 152 determines to forward park the vehicle 20.
The distance threshold Lth10 used at each of determination steps S121, S124, S126 may be different depending on whether the vehicle is forward or reverse parked. In any case, the distance threshold Lth10 may be set such that the charging cable 31 can be routed along the circumference of the vehicle 20 from the electrical supply equipment 30 to the charging port 24.
If at step S124 it is determined that the distance L12 is equal to or less than the distance threshold Lth10, then whether in the case of forward parking or in the case of reverse parking, the parking assistance controller 152 determines that the charging cable 31 can reach the charging port 24. In this case, at step S126, the parking assistance controller 152 determines whether or not L12 minus Lth10 is equal to or less than Lth13 minus Lth10. If at step S126 it is determined that L12 minus Lth10 is equal to or less than Lth13 minus Lth10, where the charging cable 31 is more likely to reach the charging port 24 in the case of reverse parking than in the case of the forward parking, then at step S127 the parking assistance controller 152 determines to reverse park the vehicle 20. If at step S126 it is determined that L12 minus Lth10 is greater than Lth13 minus Lth10, where the charging cable 31 is more likely to reach the charging port 24 in the case of forward parking than in the case of the reverse parking, then at step S128 the parking assistance controller 152 determines to forward park the vehicle 20.
This configuration can more reliably obviate a situation where the charging cable 31 is too short to reach the charging port 24 at completion of parking of the vehicle 20. In addition, the length of the charging cable 31 can be reduced, which can reduce the amount of copper cables and losses in the charging cable 31. Further, a distance between the electrical supply equipment 30 and the charging port 24 can be reduced, which allows the charging cable 31 to be more readily routed.
A third embodiment will now be described. Only differences of the third embodiment from the first embodiment will be described.
The parking assistance controller 152 of the present embodiment determines a shorter one of a distance between the charging port 24 and the electrical supply equipment 30 at completion of forward parking of the vehicle 20 and a distance between the charging port 24 on the vehicle 20 and the electrical supply equipment 30 at completion of reverse parking of the vehicle 20, and based on the determination result, determines a parking direction, that is, whether to forward park or reverse park the vehicle 20.
More specifically, the parking assistance controller 152, at step S12 shown in
At step S132 subsequent to step S131, the parking assistance controller 152 determines whether or not the first distance L13 is less than the second distance L12. If at step S132 it is determined that the first distance L13 is less than the second distance L12, then the parking assistance controller 152 determines that the charging port 24 can get closer to the electrical supply equipment 30 at completion of forward parking of the vehicle 20 than at completion of reverse parking of the vehicle 20. Therefore, the parking assistance controller 152, at step S133, determines to forward park the vehicle 20. If at step S132 it is determined that the second distance L12 is equal to or less than the first distance L13, then the parking assistance controller 152 determines that the charging port 24 can get closer to the electrical supply equipment 30 at completion of reverse parking of the vehicle 20 than at completion of forward parking of the vehicle 20. Therefore, the parking assistance controller 152, at step S134, determines to reverse park the vehicle 20.
In the present embodiment, the parking assistance apparatus 10 configured as above determines substantially the same parking directions as in the first embodiment. In situations shown in FIGS. 4E, 4H, 5F, 5G, 6D, 6I, 7D, 7I, 8F, 8G, 9E, and 9H, the parking assistance apparatus 10 of the present embodiment determines a parking direction for the vehicle 20 such that a distance between the charging port 24 and the electrical supply equipment 30 is minimized.
The present embodiment can provide the following advantage in addition to the advantage of the first embodiment.
(A3) The parking assistance controller 152 compares the first distance L12 at completion of forward parking of the vehicle 20 and the second distance L13 at completion of reverse parking of the vehicle 20, and based on the comparison result, determines a parking direction for the vehicle 20. With this configuration, an optimal parking direction for the vehicle 20 can be determined based on a relationship between the location of the charging port 24 at completion of parking of the vehicle 20 and the location of electrical supply equipment 30, which can more reliably obviate a situation where the charging cable 31 is too short to reach the charging port 24 at completion of parking of the vehicle 20. In addition, this configuration can reduce a length of the charging cable 31, thereby reducing the amount of copper cables and losses in the charging cable 31. Further, the electrical supply equipment 30 and the charging port 24 can get closer to each other, which allows the charging cable 31 to be more readily routed.
A forth embodiment will now be described. Only differences of the fourth embodiment from the first embodiment will be described.
The parking assistance controller 152 of the present embodiment is configured determine a parking location of the vehicle 20 such that the center of the vehicle 20 is offset from the center of the parking slot at completion of parking of the vehicle 20, thereby causing the location of the charging port 24 at completion of parking of the vehicle 20 to get closer to the installation location of the electrical supply equipment 30.
More specifically, at step S12 shown in
As above, the parking assistance apparatus 10 of the present embodiment determines not only a parking direction for the vehicle 20, but also a parking location of the vehicle 20, as a parking manner of the vehicle 20.
In an alternative embodiment to the present embodiment, at step S12 shown in
The present embodiment can provide the following advantage in addition to the advantage of the first embodiment.
(A4) The parking assistance controller 152 of the present embodiment is configured to determine a parking location of the vehicle 20 such that the center Cc of the vehicle 20 is offset from the center Cf of the parking slot F at completion of parking of the vehicle 20, thereby causing the location of the charging port 24 at completion of parking of the vehicle 20 to get closer to the installation location of the electrical supply equipment 30. Such a configuration that the charging port 24 can get closer to the electrical supply equipment 30 can more reliably obviate a situation where the charging cable 31 is too short to reach the charging port 24 at completion of parking of the vehicle 20. In addition, this configuration can reduce a length of the charging cable 31, thereby reducing the amount of copper cables and losses in the charging cable 31. Further, a distance between the electrical supply equipment 30 and the charging port 24 can be reduced, which allows the charging cable 31 to be more readily routed.
A fifth embodiment will now be described. Only differences of the fifth embodiment from the first embodiment will be described.
The parking assistance ECU 15 of the present embodiment includes a parking lot information acquirer 153 as indicated by a dashed line in
Parking assistance control processing performed by the parking assistance ECU 15 will now be described with reference to operations on the console 13 to initiate automatic parking in response to an operation signal transmitted from the console 13.
As shown in
As shown in
At step S22 subsequent to step S21, the electrical supply equipment recognizer 151 recognizes a location of the electrical supply equipment 30 relative to each of a plurality of empty parking slots based on the parking lot information acquired at step S20. At step S22, the same processing as that of step S11 shown in
Thereafter, at step S23, the parking assistance controller 152 determines a parking manner for each of the plurality of parking slots. That is, the parking assistance controller 152 determines, for each of the plurality of parking slots, whether to forward park or reverse park the vehicle in the parking slot. This processing of step S23 is performed by performing the processing of step S12 shown in
At step S23 subsequent to step S22, the parking assistance controller 152 estimates, for each of the plurality of parking slots, a distance between the charging port 24 and the electrical supply equipment 30 at completion of parking of the vehicle 22 in the determined parking manner. In an example of
As shown in
The present embodiment can provide the following advantage in addition to the advantage of the first embodiment.
(A5) The parking assistance controller 152 of the present embodiment is configured to perform automatic parking control such that the vehicle 20 is automatically parked in one of the plurality of empty parking slots, such as parking slots F10 and F20, in which a distance between the charging port 24 and the electrical supply equipment 30 at completion of parking of the vehicle 20 is minimal. In the case where there are a plurality of empty parking slots, this configuration can more reliably obviate a situation where the charging cable 31 is too short to reach the charging port 24 at completion of parking of the vehicle 20. In addition, this configuration can reduce a length of the charging cable 31, thereby reducing the amount of copper cables and losses in the charging cable 31. Further, a distance between the electrical supply equipment 30 and the charging port 24 can be reduced, which allows the charging cable 31 to be more readily routed.
A sixth embodiment will now be described. Only differences of the sixth embodiment from the first embodiment will be described.
The parking assistance apparatus 10 of the present embodiment is configured to, during parking assistance control, provide a notification of a parking manner to a driver of the vehicle 20 to assist the driver with driving the vehicle.
As shown in predefined operations on the console 13, the parking assistance controller 152 determines that there is a demand for parking assistance from the driver. If at step S30 it is determined that there is a demand for parking assistance from the driver, then at step S31, the parking assistance controller 152 determines a parking direction for the vehicle 20. More specifically, using the technique described in one of the first to fifth embodiments, the parking assistance controller 152 determines a parking direction for the vehicle 20.
At step S32 subsequent to step S31, the parking assistance controller 152 notifies the driver of the parking direction determined at step S31 to assist the driver with driving the vehicle 20. The parking assistance apparatus 10 includes a notification unit 17 as indicated by a dashed line in
The present embodiment can provide the following advantage in addition to the advantage of the first embodiment.
(A6) The parking assistance controller 152 is configured to, during parking assistance control, notify the driver of the vehicle 20 a parking direction via the notification unit 17. Even in the case of the vehicle 20 incorporating no automatic parking assistance control function, this configuration can more reliably obviate a situation where the charging cable 31 is too short to reach the charging port 24 on the vehicle 20 at completion of parking of the vehicle 20. In addition, this configuration can reduce a length of the charging cable 31, thereby reducing the amount of copper cables and losses in the charging cable 31.
A seventh embodiment will now be described. Only differences of the seventh embodiment from the first embodiment will be described.
The parking assistance apparatus 10 includes a display unit 18 as indicated by a dashed line in
The display unit 18 may be configured to normally display location information for the charging port 24 on the vehicle 20 or may be configured to display location information for the charging port 24 on the vehicle 20 only when it is recognized by a high-accuracy navigation device or the like that the vehicle 20 is located in a parking lot. In addition, the display unit 18 may be configured to display location information for the charging port 24 on the vehicle 20 only when the vehicle 20 is being manually driven.
The present embodiment can provide the following advantage in addition to the advantage of the first embodiment.
(A7) The parking assistance apparatus 10 of the present embodiment further includes the display unit 18 for displaying location information for the charging port 24 on the vehicle 20. This configuration allows an occupant of the vehicle 20 to readily recognize a location of the charging port 24 on the vehicle 20, which allows the vehicle 20 to be more readily parked such that the charging port 24 and the electrical supply equipment 30 can be connected.
