Abstract

This multi-car elevator system is provided with a plurality of cars, a person-detecting sensor, and a control unit. The control unit determines, on the basis of passenger presence information detected by the person-detecting sensor, whether to carry out movement of the cars from a first direction toward a second direction. When it has been determined, on the basis of the passenger presence information, that a passenger is present in a car, the control unit restricts movement of the car from the first direction toward the second direction.

Description

Multi car elevator

The present invention relates to a multi-car elevator in which a plurality of cars move on a moving path.

In recent years, a multi-car elevator in which a plurality of cars move in one moving path has been proposed. As a conventional multi-car elevator of this type, for example, there is one as described in Patent Document 1. Patent Literature 1 describes a technology related to a circulation type multi-car elevator having a plurality of car pairs in which a car is connected to both ends of two ropes arranged diagonally. Further, Patent Literature 1 discloses a technique in which a rope connecting a car pair is driven by a large number of rope drive pulleys arranged on a smooth curve or on a line where a smooth curve and a straight line are mixed.

JP 2006-11408 A

However, in the technology disclosed in Patent Document 1, when the direction of the moving direction of the car is reversed, the car moves from the vertical direction to the horizontal direction intersecting the vertical direction. When the car moves from the first direction to the second direction crossing the first direction, inertia acts on the passengers in the car, and the passengers may fall. Was.

An object of the present invention is to provide a multi-car elevator capable of preventing a change in the direction of movement of a car in a state where passengers are loaded, in consideration of the above-described problems.

In order to solve the above-mentioned problems and achieve the object, a multi-car elevator is provided with a plurality of cars that can move in a first direction and a second direction that intersects the first direction in the same moving path, A human detection sensor and a control unit are provided. The human detection sensor detects the presence or absence of a passenger in the car. The control unit determines whether or not to move the car from the first direction to the second direction based on the passenger presence / absence information on the presence / absence of the passenger detected by the human detection sensor. If the control unit determines that there is a passenger in the car based on the passenger presence information, the control unit restricts the movement of the car from the first direction to the second direction.

According to the multi-car elevator having the above configuration, it is possible to prevent the car from moving in the second direction from the first direction while the passenger is loaded.

Hereinafter, a multi-car elevator according to an embodiment will be described with reference to FIGS. In the drawings, common members are denoted by the same reference numerals.

1. First, a configuration of a multi-car elevator according to an embodiment (hereinafter, referred to as “this example”) will be described with reference to FIG.
FIG. 1 is a schematic configuration diagram showing a multi-car elevator according to the present embodiment.

The multi-car elevator 1 shown in FIG. 1 is an elevator in which a plurality of cars 10 move in a moving path 20 formed in a building structure. The multi-car elevator 1 includes a plurality of pairs (in this example, three pairs) of cars 10 on which people and luggage are placed, and a control device 6 that controls the operation of the cars 10.

The moving path 20 is provided with an ascending path 20A in which the car 10 moves up and down and a descending path 20B in which the car 10 moves down. The ascending path 20A and the descending path 20B are adjacent to each other in a horizontal direction which is a second direction orthogonal to the vertical direction which is the first direction. Hereinafter, the vertical direction is referred to as a first direction, and the horizontal direction intersecting the vertical direction is referred to as a second direction.

Furthermore, a first reversing path 20C is provided at the upper end of the ascending path 20A and the descending path 20B of the moving path 20 in the first direction, in which the direction of movement of the car 10 is reversed from ascending to descending. Further, a second reversing path 20D is provided at the lower end of the ascending path 20A and the descending path 20B of the moving path 20 in the first direction, in which the direction of movement of the car 10 is reversed from descending to ascending.

一対 A pair of cars 10 in the plurality of cars 10 are connected to an endless first main rope 21 and a second main rope 22. The first main rope 21 is mounted on a first driving pulley 23, which is an example of a driving unit, and on a first lower pulley 25. The first drive pulley 23 is installed on an upper part of the moving path 20 in the first direction, and the first lower pulley 25 is installed on a first reversing path 20C of the moving path 20.

２The second main rope 22 is mounted on a second drive pulley 24, which is an example of a drive unit, and on a second lower pulley 26. The second drive pulley 24 is installed on the upper part of the moving path 20 in the first direction, and the second lower pulley 26 is installed on the second reversing path 20D of the moving path 20. The pair of

cars

10 and 10 are arranged at symmetrical positions so as to function as counterweights when holding the first main rope 21 and the second main rope 22.

１The first main rope 21 and the second main rope 22 are provided in three sets according to the pair of the car 10. Also, three sets of the first driving pulley 23, the second driving pulley 24, the first lower pulley 25, and the second lower pulley 26 are provided in accordance with the pair of the car 10.

The three pairs of cars 10 installed as described above are driven by the three first driving pulleys 23 and the three second driving pulleys 24, respectively, at a predetermined moving speed in the moving path 20 to have the same configuration. It is configured to circulate on an orbit and stop on the same orbit. For example, the three pairs of cars 10 ascend along the ascending path 20A, and the direction of movement thereof is reversed from ascending to descending on the first reversing path 20C. In addition, the three pairs of cars 10 move from the ascending road 20A to the descending road 20B as the moving direction continuously changes from the first direction to the second direction on the first reversing path 20C.

{Circle around (3)}, the three pairs of cars 10 descend along the descending path 20B, and the direction of movement thereof is reversed from descending to ascending in the second reversing path 20D. In addition, the three pairs of cars 10 move from the descending path 20B to the ascending path 20A as the moving direction continuously changes from the first direction to the second direction on the second reversing path 20D. Thus, the three pairs of cars 10 circulate on the moving path 20.

In addition, on the floor where the car 10 stops in the building structure, when the car 10 moves up and down, when the car 10 moves down, the ascending and descending

landings

12A, 12B and 12C where people and luggage get on and off. There are provided

landing platforms

14A, 14B, 14C for people and luggage to get on and off. A hall button 13 for calling the car 10 is provided on each floor of the building structure.

After the car 10 moves up and reaches the top floor, passengers are prohibited from riding in the car 10 until the car 10 moves down via the

drive pulleys

23 and 24. For this reason, the passenger of the car 10 must get off on the top floor of the ascending road 20A. Similarly, after the car 10 moves down and reaches the lowest floor, the passenger is prohibited from riding on the car 10 until the car 10 moves up via the

lower pulleys

25 and 26. For this reason, the passenger of the car 10 must get off on the lowest floor of the descending path 20B. Therefore, the hall button 13 is not installed in the ascending and descending hall 12A on the top floor and the descending and ascending hall 14B on the lowest floor.

FIG. 1 shows an example in which the car 10 moves in a clockwise rotation direction. If the car 10 moves in only one direction (for example, clockwise) as an operation of the multi-car elevator 10, the hall button 13 is not required for the ascending and descending

landings

12A and 14B. On the other hand, when the car 10 moves in both the clockwise direction and the counterclockwise direction, the hall buttons 13 may be installed in the landing floor 12A on the top floor and the landing floor 14B on the bottom floor. Then, in the operation in which the car 10 moves in both directions, when the car 10 moves clockwise, the hall buttons 13 provided on the top floor landing 12A and the bottom floor landing 14B are invalidated. When the car 10 moves in the counterclockwise direction, the hall buttons 13 installed at the lowest floor landing 12B and the highest floor landing 14A are disabled. Thereby, the same effect as in the above-described operation example can be obtained.

<Control device>
The control device 6 controls the operation of the multi-car elevator 1 and is configured by a computer. The computer is hardware used as a so-called computer. The computer includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). Further, the computer includes a nonvolatile storage and a network interface. The control procedure performed by each unit included in the control device 6 is a program stored in a ROM or a program loaded from an external device into a RAM and stored.

Such a control device 6 includes three loop controllers 7 that control the movement or stop of the car 10 by driving the drive pulleys 23 and 24, and an overall controller 8 that centrally controls the operations of the three loop controllers 7. Is provided.

<Loop controller>
One of the three loop controllers 7 (“loop controller A” in the figure) includes a first main rope 21 and a second main rope 22 that are held by a pair of cars 10 of the three pairs of cars 10. The pair of drive pulleys 23 and 24 are mounted and controlled in synchronization with each other. Similarly, another one of the loop controllers 7 (“loop controller B” in the figure) includes a first main rope 21 and a second main rope that are held by the other pair of cars 10 of the three pairs of cars 10. A pair of drive pulleys 23 and 24 on which a rack 22 is mounted are driven and controlled in synchronization with each other. Still another loop controller 7 (“loop controller C” in the figure) includes a first main rope 21 and a second main rope 22 that are gripped by another pair of cars 10 of the three pairs of cars 10. The pair of drive pulleys 23 and 24 mounted on the shelf are driven and controlled in synchronization with each other.

Each loop controller 7 can determine the moving direction and the moving amount of the car 10 controlled by each loop controller 7 based on the detection signal input from the encoder. Thereby, each loop controller 7 obtains the traveling speed of the car 10 controlled by each loop controller 7 and outputs information on the traveling speed of the car 10 to the overall controller 8.

The overall controller 8 controls the operations of all the cars 10 in the moving path 20 based on the information on the traveling speed of the car 10 input from each loop controller 7. The overall controller 8 can control the driving of the driving pulleys 23 and 24.

1-2. Next, the configuration of the car 10 will be described with reference to FIGS. 1 and 2.
FIG. 2 is a block diagram showing a control system of the car 10.

As shown in FIGS. 1 and 2, the car 10 includes a car-side door 15, a human detection sensor 31, a car position detection sensor 32, a car-side control unit 30, a notification device 37, a door motor 38, It has.

The human detection sensor 31 is installed inside the car 10 and detects the presence or absence of a passenger in the car 10. As the human detection sensor 31, for example, a load sensor that detects the load of a passenger who has entered the car 10 or a camera that detects the presence or absence of a passenger by photographing the inside of the car 10 is applied. The passenger presence / absence information detected by the human detection sensor 31 is output to the car-side control unit 30.

The car position detection sensor 32 detects the current position of the car 10. Then, the position information of the car 10 detected by the car position detection sensor 32 is output to the car side control unit 30. The notification device 37 is controlled by a notification control device 35 of the car-side control unit 30, which will be described later, and notifies the passengers of the car 10 of various kinds of information. As the notification device 37, for example, a device for notifying passengers of information such as a display device and a pilot lamp, a device for notifying passengers by voice such as a speaker or a buzzer, or a device combining these devices Is applied.

The door motor 38 is controlled by a door control device 36 of the car-side control unit 30 described later to open and close the car-side door 15 provided in the car 10.

The car-side control unit 30 controls the car 10 and is constituted by a computer. The computer is hardware used as a so-called computer. The computer includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). Further, the computer includes a nonvolatile storage and a network interface. The control procedure performed by each unit included in the car-side control unit 30 is a program stored in a ROM or a program loaded from an external device into a RAM and stored.

The car-side control unit 30 includes a notification determination unit 33, a door open / close determination unit 34, a notification control device 35, a door control device 36, and a communication unit 39. The notification determination unit 33 determines whether or not to perform the notification based on the passenger presence information received from the human detection sensor 31 and the position information of the car 10 from the car position detection sensor 32. When the notification determination unit 33 determines that the notification is to be performed, the notification determination unit 33 outputs the notification instruction information to the notification control device 35. Then, the notification control device 35 controls the notification device 37 based on the notification instruction information from the notification determination unit 33.

The door open / close determination unit 34 determines whether the car side door 15 is open or closed based on the passenger presence information received from the human detection sensor 31 and the position information of the car 10 from the car position detection sensor 32. Then, the door open / close determination unit 34 outputs the open / close determination information to the door control device 36. The door control device 36 controls opening and closing of the door motor 38 based on the opening / closing determination information.

The communication unit 39 is configured to be able to transmit and receive information to and from the car-side control unit 30 and the control device 6 of the other car 10 and an external control center. The communication unit 39 outputs the position information of the car 10 detected by the car position detection sensor 32 to the control device 6, the notification information of the notification control device 35, and the like. Further, the communication unit 39 receives the position information of the other car 10 directly from the communication unit 39 of the car-side control unit 30 of the other car 10 or via the control device 6.

2. Next, an example of the reversing operation of the multi-car elevator 1 having the above-described configuration will be described with reference to FIGS.
FIG. 3 is a flowchart showing the inversion operation. 4 to 6 are explanatory diagrams showing the reverse operation of the car.

The car-side control unit 30 detects that the car 10A is traveling near the top floor or the lowest floor from the car position information by the car position detection sensor 32 (step S11). In the example shown in FIG. 4, it is shown that the car 10A moves up the ascending path 20A and approaches the ascending platform 12A provided on the top floor.

Next, the car-side control unit 30 determines whether or not the passenger 100 is in the car 10A based on the passenger presence information of the human detection sensor 31 (step S12). In the process of step S12, when the car-side control unit 30 determines that the passenger 100 is not present in the car 10A (NO in step S12), the door open / close determination unit 34 determines that the car 10A has stopped on the top floor. Open / close determination information indicating that the car-side door 15 is not opened is output to the door control device 36. Thereby, even if the car 10A stops on the top floor, the car-side door 15 remains closed (step S31).

(6) Then, as shown in FIG. 6, the car 10A is controlled by the control device 6 to start a lateral movement in the second direction, that is, a reverse movement (step S28). Thereby, the moving direction of the car 10A continuously changes from the first direction to the second direction, and the direction of the moving direction is reversed from ascending to descending on the first reversing path 20C.

On the other hand, in the process of step S12, when the car-side control unit 30 determines that the passenger 100 is present in the car 10A (YES determination in step S12), the notification determination unit 33 issues a notification instruction to the notification control device 35. Output information. The notification control device 35 that has received the notification instruction information notifies the passenger 100 via the notification device 37 provided in the car 10A that the car 10A stops at the top floor and gets off the ascending platform 12A. (Step S13).

Next, the door open / close determination unit 34 of the car side control unit 30 outputs to the door control unit 36 the open / close determination information for opening the car side door 15 when the car 10A stops on the top floor. Then, as shown in FIG. 5, when the car 10A stops on the top floor, the door control device 36 drives the door motor 38 to open the car-side door 15 of the car 10A (step S14).

When performing the processing in step S14, the notification control device 35 notifies the information about the inability to get on the car 10A from the ascending platform 12A via the notification device 37. Thus, it is possible to suppress the passenger 100 from getting on the car 10A from the ascending platform 12A on the top floor.

Next, the notification determination unit 33 of the car-side control unit 30 sets the number of notifications N to “1” (step S15). In addition, the notification determination unit 33 of the car-side control unit 30 sets a notification count threshold Ns and a notification time interval threshold Ts. The number-of-notifications threshold value Ns and the notification time interval threshold value Ts are based on, for example, a distance K from a car 10B located behind the car 10A performing the reversing operation in the moving direction (hereinafter, referred to as a "rear car 10B"). Is set. The distance K between the rear car 10B and the car 10A is calculated from the position information of the car 10A and the position information of the rear car 10B obtained via the communication unit 39.

When the distance K between the car 10A and the rear car 10B is relatively long, the values of the notification count threshold Ns and the notification time interval threshold Ts are set to be large. When the distance K between the car 10A and the rear car 10B is relatively short, the values of the notification count threshold Ns and the notification time interval threshold Ts are set to be small.

The setting process of the notification count threshold value Ns and the notification time interval threshold value Ts is not limited to the above-described example. For example, the usage status of the car 10 other than the car 10A performing the reversing operation and various other Is set according to the information of. When the usage status is large, that is, when a large number of other rides 10 are used, the notification count threshold Ns and the notification time interval threshold Ts are set to small values. In this case, if it takes a long time to get off, the effect on the operation efficiency is large. Therefore, a notice for urging the getting off may be given, including information on the use status.

{Circle around (1)} When the usage status is small, that is, when the usage of the other cars 10 is small, the values of the notification count threshold Ns and the notification time interval threshold Ts are set to be large. That is, the values of the notification count threshold value Ns and the notification time interval threshold value Ts are set according to the status of the car 10 other than the car 10A that performs the inversion operation.

Next, the car-side control unit 30 sets the notification time interval T to “0” (Step S17). Further, the car-side control unit 30 determines whether or not the passenger 100 is in the car 10A based on the passenger presence / absence information of the human detection sensor 31 (step S18).

In the processing of step S18, when the car-side control unit 30 determines that the passenger 100 is not present in the car 10A (NO determination in step S18), the passenger 100 is raised from the car 10A as shown in FIG. It turns out that we got off at 12A. Then, the car-side control unit 30 drives the door motor 38 via the door control device 36 to close the car-side door 15 (Step S27). Then, as shown in FIG. 6, the car 10A starts a lateral movement, that is, a reverse movement under the control of the control device 6 (step S28).

On the other hand, in the process of step S18, when the car-side control unit 30 determines that the passenger 100 is still in the car 10A (YES determination in step S18), the notification determination unit 33 notifies the notification control device 35. Outputs instruction information. The notification control device 35 that has received the notification instruction information notifies the user to get off the ascending platform 12A via the notification device 37 provided in the car 10A (step S19).

{Circle around (4)} The car-side control unit 30 counts the time from the notification through the notification device 37 in the processing of step S19 as the notification time interval T. Next, the notification determination unit 33 determines whether or not the notification time interval T is less than the notification time interval threshold value Ts (T <Ts) (Step S20).

In the process of step S20, when the notification determination unit 33 determines that the notification time interval T has exceeded the notification time interval threshold Ts (NO determination in step S20), the notification count N is less than the notification count threshold Ns (N <Ns). ) Is determined (step S21). In the process of step S21, when the notification determination unit 33 determines that the number of notifications N is smaller than the notification number threshold Ns (YES determination in step S21), it adds "1" to the number of notifications N (step S22). Then, the car-side control unit 30 returns to the process of step S17, performs the above-described process, and notifies the passenger 100 in the car 10 to get off again.

Further, in the process of step S21, when the notification determination unit 33 determines that the number of notifications N exceeds the number-of-notifications threshold value Ns (NO determination in step S21), the car-side control unit 30 communicates with the external unit via the communication unit 39. Notify the control center. Then, the observer of the control center warns the passenger 100 to get off via the communication unit 39 (step S23).

In this example, an example is described in which the number of times of notification by the notification device 37 is applied as the timing of notification to the outside, but the present invention is not limited to this. As the timing to notify the outside, various kinds of timings such as a time after the car 10A stops at the top floor or the lowest floor, a time when the car side door 15 is opened, and the like are applied.

Next, the car-side control unit 30 or the supervisor of the control center determines whether or not the passenger 100 is in the car 10A based on the passenger presence information of the human detection sensor 31 (step S24). In the process of step S24, when the car-side control unit 30 or the monitoring person determines that the passenger 100 is not in the car 10A (NO determination in step S24), the car-side control unit 30 sends the information via the door control device 36. By driving the door motor 38, the car-side door 15 is closed (step S27). Then, as shown in FIG. 6, the car 10A is controlled by the control device 6 to start a lateral movement, that is, a reversing operation (step S28).

On the other hand, in the process of step S24, when the car-side control unit 30 or the monitoring person determines that the passenger 100 is in the car 10A (YES determination in step S24), the control center sends the building management center of the building structure. (Step S25).

When the passenger 100 gets off the car 10A and the guard of the building management center confirms that there is no passenger 100 in the car 10A (step S26), the car-side control unit 30 transmits the door motor via the door control device 36. The car 38 is driven to close the car-side door 15 (step S27). Thus, the car-side door 15 does not close until all the passengers 100 get off the car 10A. Therefore, the reversing operation in the car 10A is restricted until all the passengers 100 get off the car 10A.

Then, as shown in FIG. 6, the car 10A starts the lateral movement, that is, the reverse movement, under the control of the control device 6 (step S28). As a result, the reversing operation of the car 10A by the multi-car elevator 1 of the present example is completed.

As described above, according to the multi-car elevator 1 of this example, when the passenger 100 is placed on the car 10, the movement of the car 10 from the first direction to the second direction is restricted. That is, it is possible to prevent the reverse operation of the car 10 from being performed while the passenger 100 is placed on the car 10, and to provide the multi-car elevator 10 with high safety.

Further, when the car 10 moves from the first direction to the second direction with the passenger 100 placed on the car 10, the moving speed of the car 10 is reduced to prevent the passenger from falling down. It was necessary to do so, and the operating efficiency was reduced. On the other hand, in the multi-car elevator 1 of this example, when the car 10 moves from the first direction to the second direction, the passenger 10 is not placed on the car 10. As a result, when the car 10 moves from the first direction to the second direction, the car 10 can be moved without reducing the moving speed of the car 10, and the operation of the multi-car elevator 1 can be performed. Efficiency can be improved.

前 In addition, before the car 10 arrives at the ascending / descending platform 12A on the top floor or the descending / descending platform 14B on the lowest floor, it is possible to urge passengers to prepare for getting off by notifying them of their exit. As a result, it is possible to smoothly get off to the ascending / descending platform 12A or the descending / descending platform 14 on the top floor or the lowest floor.

Furthermore, when the car 10 stops at the top floor or the bottom floor, the car is notified of getting off. Then, when the number of times of notification reaches the threshold value, the control center notifies the external control center, and the external control center also notifies the passenger of getting off. As described above, by giving the step-off notification step by step, the passenger 100 can be securely dismounted from the car 10, and when the car 10 performs the reversing operation, the fact that the passenger 100 is in the car 10 is confirmed. Can be prevented.

In addition, as shown in the processing of step S31, the vehicle 10 arrives at the top floor or the lowest floor immediately before the moving direction of the car 10 changes from the first direction to the second direction in a state where the passenger 100 is not in the car 10. In this case, the car-side door 15 of the car 10 is not opened. Thus, it is possible to prevent the passenger 100 from accidentally getting into the car 10 from the ascending platform 12A on the top floor or the descending platform 14B on the lowest floor.

Note that, in the multi-car elevator 1 of the present example, when the pair of

cars

10 and 10 hold the first main rope 21 and the second main rope 22, they are symmetrically positioned so as to function as a counterweight. Are located in Therefore, when one of the pair of

cars

10, 10 approaches the top floor, the other car 10 approaches the bottom floor. Therefore, when there is no passenger 100 in both the

cars

10 and 10 of the pair of

cars

10 and 10, the inversion operation may be performed without stopping the

cars

10 and 10 on the top floor or the bottom floor. As a result, it is possible to prevent the moving speed of the car 10 from decreasing, and it is possible to improve the operation efficiency of the multi-car elevator 1.

When the passenger 100 is present in at least one of the pair of

cars

10 and 10, the

cars

10 and 10 are stopped at the top floor or the bottom floor. At this time, the car-side door 15 of the car 10 without the passenger 100 is not opened.

The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the appended claims.

In the embodiment described above, the notification determination unit 33 for determining the notification, the door open / close determination unit 34, and the communication unit 39 are provided in the car-side control unit 30 of the car 10, and the car-side control unit 30 is illustrated in FIG. The example in which the notification and the door opening / closing processing are performed has been described, but the invention is not limited thereto. For example, the control device 6 that controls the entire multi-car elevator 1 may be provided with the notification determination unit 33, the door open / close determination unit 34, and the communication unit 39, and the control device 6 may perform the notification and the door open / close processing illustrated in FIG. .

Furthermore, as the multi-car elevator, a multi-car elevator in which a plurality of cars 10 circulate in one direction has been described, but the present invention is not limited to this. For example, the present invention can also be applied to a multi-car elevator in which a plurality of cars can move on the moving path 20 in both directions of ascending and descending.

In addition, as a driving method of the car of the multi-car elevator, a driving method provided with a driving pulley or a hoist, or a linear driving unit is provided, and an induced current is applied to a main rope connected to the car, so that a main driving is performed. A driving method in which a driving force (thrust) is generated on the rope itself may be used. Further, the present invention can be applied to a self-propelled multi-car elevator in which a driving unit is provided in a car.

The number of cars provided in the multi-car elevator 1 is not limited to six, and the number of cars may be five or less, or seven or more.

In the above-described embodiment, an example is described in which the vertical direction, which is the vertical direction, is applied as the first direction in which the car moves, but the present invention is not limited to this. For example, the first direction may be a horizontal direction orthogonal to the vertical direction, or an oblique direction inclined from the horizontal direction, the vertical direction, and the horizontal direction. As the multi-car elevator, a multi-car elevator in which at least a car can move in a first direction and a second direction intersecting the first direction is applied.

In addition, the multi-car elevator is not limited to a multi-car elevator provided with a landing along the first direction. For example, the present invention can be applied to a multi-car elevator in which a traveling path extends in a first direction and a second direction, and a landing is provided in both the first direction and the second direction. In this case, the above-described processing is applied to the operation immediately before the car moves along the corner where the car turns from the first direction to the second direction in the moving path.

In this specification, words such as "parallel" and "orthogonal" are used, but these do not mean only strictly "parallel" and "orthogonal" but include "parallel" and "orthogonal". Further, it may be in a state of “substantially parallel” or “substantially orthogonal” within a range in which the function can be exhibited.
