Abstract

PROBLEM TO BE SOLVED: To give the least possible degradation of service to elevator users by performing preferential allotment control corresponding to a change in traffic demand of an elevator. SOLUTION: An operation condition is classified into three levels, 'no-jam', 'normal' and 'jam', and judgement values are set corresponding to the levels. Learning that a B-number car 1-B, e.g. exists as a simultaneous response car in accordance with the detection of simultaneous response detecting mean 7, allotment control means 5 inputs an evaluation value for the B-number car 1-B from allotment evaluation computing means 6 and compares it with the judgement value corresponding to the 'normal' condition as a discrimination result of operation condition detecting means 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management controller for performing priority assignment control.

[0002]

2. Description of the Related Art In elevator group management control, priority allocation control is generally performed to improve the operation efficiency of an elevator car. Priority assignment control means that when a user at a landing on a certain floor presses a hall call button and a new hall call registration occurs, a user in the car presses the car call button to release the floor call. If there is a car for which car call registration has already been performed (such a car may be called a "simultaneous response car"), that car is given priority over other cars and the new hall call is made. This is control for assigning to registration.

[0003] However, the time required for the simultaneous response car to arrive at the floor where the above-mentioned new hall call registration has occurred is prolonged, so that a user of the floor is in a so-called long wait state, and the service is significantly reduced. When there is a possibility, priority allocation control is not performed. At this time, whether or not to enter the long waiting state is determined based on whether or not the evaluation value as an index of the time until the car arrives at the destination floor is equal to or less than a predetermined determination value. It has become.

[0004]

However, the operating condition of the elevator, that is, the traffic demand of the elevator usually changes with time, but the conventional elevator group management control device uses a fixed value for the priority assignment control. As a result, it was not possible to respond to changes in traffic demand, and the user often felt discomfort due to frequent long wait states.

[0005] For example, during lunch time, the demand for elevator traffic becomes very intense, and it is unavoidable that the user side will be in a long waiting state to some extent in such a time zone, and the evaluation value slightly exceeds the judgment value. Even so, it may be better to assign a simultaneous response car. Conversely, in a time zone where elevator traffic demand is low, the fact that the evaluation value is equal to or less than the determination value does not necessarily mean that the best possible service is to assign a simultaneous response car. As described above, it has been difficult for the conventional device to always provide a service of a certain level or higher to the elevator user.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and performs priority assignment control in response to changes in elevator traffic demand, and manages elevator groups capable of preventing service degradation for elevator users as much as possible. It is intended to provide a control device.

FIG. 1 is a block diagram showing the configuration of a first embodiment of the present invention. Two cars 1-A, 1
-B (in the present embodiment, only two cars are described for simplicity of description and illustration) are controlled by the unit control devices 2-A and 2-B, respectively. I have. A hall call button 3-1 at the elevator hall on each floor
３−3-N are installed, and a hall call request from each hall call button is registered by the hall call registration means 4.

The hall call registration means 4 notifies the allocation evaluation calculation means 6 and the simultaneous response detection means 7 when a new hall call registration is made. Upon receiving this notification, the assignment evaluation calculation means 6 determines that the operating state information of the car control devices 2-A and 2-B (not only the current positions of the cars 1-A and 1-B, but also that the car will be stopped in the future). (Including information about the floors that have become)
Based on this, the assignment evaluation value of each car is calculated and output to the assignment control means 5. Further, upon receiving this notification, the simultaneous response detecting means 7 detects whether or not there is a simultaneous response car heading to the floor where the new hall call registration has been made, and outputs the detection result to the assignment control means 5. It is supposed to. Further, the operation state detecting means 8 detects the operation state, that is, the degree of elevator traffic demand, based on the input of various information from the unit control device 2-A and the unit control device 2-B. , And outputs the detection result to the assignment control means 5. Then, the assignment control means 5 inputs the data from the assignment evaluation calculation means 6, the simultaneous response detection means 7, and the operation state detection means 8, and assigns the optimum car from among the cars of each car to a new hall call registration. Assignment control is performed.

Next, the operation of the first embodiment shown in FIG. 1 will be described. FIG. 2 is an explanatory diagram showing a car position and a call registration state of each car at a certain time. As shown in this figure, the car of the car A is currently located on the first floor, and is in a state where the car for the hall call registration on the third floor has been assigned. Further, the car of the No. B car is located on the second floor, and the car call registration on the fifth floor has been performed. In this state, it is assumed that a user at the hall on the fifth floor presses the hall call button, and a new hall call registration occurs.

Then, the hall call registration means 4 notifies the allocation evaluation calculation means 6 and the simultaneous response detection means 7 that the above-mentioned new hall call registration has occurred. Upon receipt of the notification, the assignment evaluation calculating means 6 determines that the assignment evaluation value of the car A is "20" and the assignment evaluation value of the car B, as shown in Table 1 of FIG. It is calculated that the value is “10”. Simultaneous response detection means 7 detects the presence of a car B on which the car call registration on the fifth floor is performed as a simultaneous response car corresponding to the new hall call registration on the fifth floor, and assigns the detection result to allocation control. Output to means 5.

The operation state detecting means 8 detects the operation state from the operation state information of the A-unit, the B-unit, and other units. In the present embodiment, the operation state levels are divided into three levels of “quiet”, “normal”, and “congested”, and the operation state detecting means 8 determines that the operation state is “normal” at the above time. are doing.

The assignment control means 5 includes a simultaneous response detection means 7
Based on the detection, the car 1 of car B as a simultaneous response car
When it is known that B exists, the evaluation value of the car 1-B of the B-th car is inputted from the assignment evaluation calculating means 6, and the evaluation value corresponding to the "normal" state which is the determination result of the operation state detecting means 8 is obtained. Compare with value. Here, the assignment control means 5 stores the determination values corresponding to each level as shown in Table 2 of FIG. 12 in its own memory.

In the above case, the evaluation value of the B-unit “1”
Since "0" is smaller than the determination value "25" in the "normal" state, the assignment control means 5 determines that the car of the B car will not be in the long waiting state even if the car of the B car is moved to the fifth floor. It is assumed that car 1-B is assigned to a new hall call registration generated on the fifth floor.

As described above, the assignment control means 5 has different judgment values depending on the degree of traffic demand, and determines the judgment value to be applied based on the detection result of the operation state detecting means 8. Like that. Therefore, according to the configuration of FIG. 1, when determining whether or not to perform the priority assignment control on the simultaneous response car, it is possible to perform an appropriate determination according to the traffic demand situation of the elevator,
It is possible to increase the operation efficiency of the elevator and prevent the service for the user from being reduced as much as possible.

FIG. 3 is a block diagram showing the configuration of the second embodiment of the present invention. This embodiment relates to a double deck elevator group management control device. That is, the car of Unit A is the upper car 1-AU and the lower car 1-AL
And the car of Unit B is the upper car 1-BU
And the lower car 1-BL. Components other than the car are the same as those in FIG.

Next, the operation of the second embodiment shown in FIG. 3 will be described. FIG. 4 is an explanatory diagram showing a car position and a call registration state of each car at a certain time. As shown in this figure, at present, the lower car 1-AL of Unit A is on the first floor and the upper car 1
-AU is located on the second floor and the lower car 1-AL is assigned to the hall call registration on the fifth floor. The lower car 1-BL of Unit B is located on the second floor, and the upper car 1-BU is located on the third floor. However, none of the cars have been registered for call and their assignments have been made. Stopped in the direction. In this state, it is assumed that a user at the hall on the sixth floor presses the hall call button, and a new hall call registration occurs.

Then, the hall call registration means 4 notifies the allocation evaluation calculation means 6 and the simultaneous response detection means 7 that the above-mentioned new hall call registration has occurred. Upon receiving this notification, the assignment evaluation calculating means 6 determines the evaluation value of the upper car 1-AU as "15" and the lower car 1 as shown in Table 3 of FIG. It is calculated that the evaluation value of the AL is “20”, the evaluation value of the upper car 1-BU is “10”, and the evaluation value of the lower car 1-BL is “12”.
Simultaneous response detecting means 7 is provided as a simultaneous response car corresponding to the registration of a new hall call on the sixth floor.
U (the lower car 1-AL “the other car”) is detected, and the detection result is output to the assignment control means 5. Basket 1 on this
-Although the AU does not register car calls on the 6th floor, the lower car 1-AL is actually registered on the 5th floor, which is the adjacent floor of the 6th floor, so it is in effect. It can be treated as a simultaneous response car.

At this time, the operation state detecting means 8 has determined that the current operation state is "quiet". When the assignment control means 5 knows that the upper car 1-AU exists as a simultaneous response car based on the detection result of the simultaneous response detection means 7, the assignment evaluation arithmetic means 6 sends the upper car 1-A
The evaluation value of U is inputted, and this is compared with the judgment value corresponding to the “quiet” state which is the judgment result of the operation state detecting means 8.
In this case, the assigned evaluation value of the upper car 1-AU is "15",
The judgment value corresponding to the “quiet” state is “10” (Table 2
reference). That is, evaluation value: “15”> judgment value: “10”
Therefore, if the upper car 1-AU of the car A is assigned to the new hall call registration on the sixth floor, it will be in a long waiting state. Therefore, in this case, the assignment control means 5 assigns the upper car 1-BU of the car B having the best assignment evaluation value.

FIG. 4 shows that the lower car 1-AL of Unit A has 5
6 when assigned for floor call registration
This shows the situation where a new hall call registration has occurred on the floor, but if the lower car 1-AL of Unit A is assigned for the floor call registration on the 6th floor, a new hall call registration on the 6th floor is shown. Occurs, the evaluation value of the lower car 1-AL may be compared with the determination value, as in the case of the first embodiment.

As described above, also in the configuration of FIG. 3 for a double deck elevator, the assignment control means 5
The determination values have different values depending on the degree of traffic demand, and the determination value to be applied is determined based on the detection result of the operation state detection means 8. Therefore, in the case of the configuration of the second embodiment in FIG. 3, as in the first embodiment, it is possible to make an appropriate determination according to the situation of the traffic demand of the elevator, and improve the operation efficiency of the elevator. As a result, it is possible to prevent the service for the user from being reduced as much as possible.

Next, a third embodiment of the present invention will be described. The third embodiment has a configuration similar to that of the first embodiment in FIG. 1, and further limits the detection method of the operation state detection means 8 in the first embodiment. That is, the operation state detecting means 8 in this embodiment detects the degree of the traffic demand based on the average value of the non-response time of each car within a predetermined time in the past.

For example, as shown in Table 4 of FIG. 13, the operation state detecting means 8 measures the unresponsive time for the past 5 minutes for each car, and calculates the average unresponsive time, which is the average value, of 5 minutes.
If it is ~ 15 seconds, it is determined to be in a "quiet" state, if it is 15 to 35 seconds, it is determined to be a "normal" state, and if it is 35 to 45 seconds, it is determined to be a "congested" state.

Then, as in the case described in the first embodiment, it is assumed that both the car A and the car B are in the state shown in FIG. 2, and the operation state detecting means 8 calculates the average non-response time in the past 5 minutes by 40. Suppose that it was calculated as seconds. Then, the operation state detecting means 8 determines the current state as the “congested” state, and notifies the allocation control means 5 of the determination result. Assignment control means 5
Receives this notice, the assigned evaluation value "1
0 ”and a judgment value“ 30 ”corresponding to the“ congested ”state, and the evaluation value:“ 10 ”<the judgment value“ 30 ”.
The car 1-B of the car B is assigned to a new hall call registration generated on the fifth floor.

According to the third embodiment, since the operation state detecting means 8 determines the degree of traffic demand based on the average value of the non-response times within a predetermined time in the past, the actual traffic demand is reflected. It is possible to easily perform the determined determination.

FIG. 5 is a block diagram showing the configuration of the fourth embodiment of the present invention. In this embodiment, an optimum pattern is selected from change patterns of judgment values created in advance, and priority allocation control is to be performed using the selected pattern. That is, the configuration in FIG. 5 is obtained by adding the learning unit 9 to the configuration in FIG. As shown in Table 5 of FIG. 13, the learning means 9 determines the pattern 1 in which the judgment value differs for each of the states of “quiet”, “normal”, and “congested”.
To 3 are prepared in advance, and the unit control devices 2-A,
The optimum pattern is selected from the patterns 1 to 3 based on the input of the operation state information of the 2-B and other unit control devices, and the selected pattern is output to the assignment control means 5.
The assignment control means 5 performs priority assignment control using the pattern selected by the learning means 9.

For example, it is assumed that both the A-unit and the B-unit are in the state shown in FIG. 2, and that the learning means 9 selects the pattern 2 from Table 5 based on the operating state information of each unit.
It is also assumed that the operation state detection means 8 has determined that the current operation state is a “congested” state. Assignment control means 5
Is inputted with the calculation result of the assignment evaluation calculation means 6, the detection result of the simultaneous response detection means 7, the discrimination result of the operation state detection means 8, and the selection result of the learning means 9, respectively. Assignment evaluation value “−10” for −B
And the determination value “35” corresponding to “congestion” in Pattern 2 of Table 5 is compared. And the evaluation value: “10” <
Judgment value: "35", so that the car 1-B of this car B
Is assigned to a new hall call registration that has occurred on the fifth floor.

According to the fourth embodiment, by utilizing the function of the learning means, a more appropriate judgment value can be used, and the operation efficiency of the elevator can be further improved.

FIG. 6 is a block diagram showing the configuration of the fifth embodiment of the present invention. In this embodiment, the detection of the degree of traffic demand is performed based on the average value of the detected loads in the car within a predetermined time in the past. That is, the configuration in FIG. 6 is obtained by adding the load detecting means 10 to the configuration in FIG. This load detecting means 10
Is the last 5 for each car as shown in Table 6 in FIG.
The load in the car for a minute was measured and their average value was 0-32.
If it is 4 kg, it is determined that the state is “quiet”, and 325 to 649
If it is kg, it is determined to be in the “normal” state, and
If the weight is kg, it is determined that the state is "congested". In addition, the maximum loading load of each car shall be 1300 kg (capacity for 20 people).

Now, it is assumed that the cars A and B are in the state shown in FIG. 2, and that the load detecting means 10 has detected that the average load in the car for the past 5 minutes is 390 kg. The operation state detection means 8 receives the detection result, determines that the current operation state is the “normal” state, and notifies the assignment control means 5 of the determination result. Upon receiving this notice, the assignment control means 5 assigns an assignment evaluation value “10” of the B-unit,
The judgment value “25” corresponding to the “normal” state is compared with the evaluation value: “10” <judgment value “25”, so that the car 1-B of the car B has a new landing generated on the fifth floor. Assign to call registration.

According to the fifth embodiment, since the degree of traffic demand is determined based on the number of occupants in the car, it is possible to use a determination value more suited to the actual situation. In addition, the technique of detecting the operation state based on the average value of the load detection values in the car within a predetermined time in the past as in this embodiment, and the technique of detecting the operation state in the predetermined time in the past as in the fourth embodiment. By combining with a technique for detecting the operation state based on the average value of the unresponsive time of the car, it is also possible to adopt a configuration for more accurately detecting the degree of traffic demand.

FIG. 7 is a block diagram showing the configuration of the sixth embodiment of the present invention. In this embodiment, a plurality of time zones in which traffic demand is expected to change are set in advance, and the determination value is switched according to the time zone to which the current time belongs. That is, the configuration of FIG. 7 is provided with a time zone management unit 11 instead of the operation state detection unit 8 in FIG. As shown in Table 7 of FIG. 14, the time zone method management means 11 divides one day into five times, “at work”, “at normal times”, “at lunch”, “at work”, and “at idle”. The time zone is divided, and information about which time zone the current time point belongs to is notified to the assignment control means 5. And the assignment control means 5
Stores a judgment value corresponding to each time zone in advance, and uses one of the judgment values based on the notification from the time zone method management unit 11.

Now, suppose that the A-unit and the B-unit are in the state shown in FIG. 2 and the current time belongs to “at lunch”.
The assignment control means 5 assigns the assignment evaluation value “10” of the Unit B
And the determination value “35” corresponding to “at lunch” in Table 7, and the evaluation value: “10” <the determination value “35”.
The car 1-B of the car B is assigned to a new hall call registration generated on the fifth floor.

According to the sixth embodiment, in an office building or the like in which the degree of traffic demand in each time zone is substantially patterned, the judgment value is varied in accordance with the traffic demand,
A configuration that can improve the operation efficiency can be easily realized.

FIG. 8 is a block diagram showing the configuration of the seventh embodiment of the present invention. This embodiment relates to a double-deck elevator group management control device as in the second embodiment of FIG. 3, in which the determination value is varied according to the driving method. That is, the configuration in FIG. 8 is obtained by adding the operation mode management unit 12 to the configuration in FIG.

The operation mode management means 12 selects one of the operation modes "double operation", "semi-double operation", and "single operation" to operate the elevator. The assignment control means 5 is notified. The operation state detecting means 8
As in the case of the third embodiment, the non-response time of the past 5 minutes is measured for each car, and if the average non-response time, which is the average value thereof, is 5 to 15 seconds, the car is determined to be in a “quiet” state If it is 15 to 35 seconds, it is determined that the state is “normal” and 3
If the time is 5 to 45 seconds, it is determined that the state is "congested".

The assignment control means 5 includes the operation mode management means 1
2 and the discrimination result from the operation state detecting means 8 are input, and priority assignment control is performed using the judgment values corresponding to both the driving method and the operation state.
That is, the assignment control means 5 has a judgment value table as shown in Table 8 of FIG.

Here, the operation modes will be briefly described. First, "double operation" is, for example, an operation mode in which a lower car is set to an odd floor and an upper car is set to an even floor. . Therefore, before getting into the car, the user checks whether the destination floor he / she is going to go to is an odd or even floor, and then goes to the car where he / she is to land. You have to get in without mistake. This method can be said to improve the operating efficiency at the expense of user convenience to some extent.

"Semi-double operation" means a departure reference floor (for example, the first floor for a lower car and the second floor for an upper car).
Only for passengers who get on from, make sure that the destination floor is an odd-numbered floor or an even-numbered floor, get on board, and after departure from the departure reference floor, both the lower and upper cars will have any floor It is a driving method that allows you to land on the ground.
The “semi-double operation” is a driving method that is more user-friendly than the “double operation”.

The "single operation" is an operation system in which either the lower car or the upper car is closed and the user is placed on only one of the cars. This driving method is the same as that of a normal elevator other than the double deck elevator. However, when performing the "single operation", since the closed car projects upward or downward on the top floor or the lowest floor, extra space must be secured accordingly.

Next, the operation of the seventh embodiment shown in FIG. 8 will be described. Now, as in the case of the second embodiment in FIG. 3, it is assumed that the car position and the call registration state of each car are in the state shown in FIG. 4, and that "semi-double operation" is further performed.

As shown in Table 3 of FIG. 12, the assignment evaluation calculating means 6 determines that the evaluation value of the upper car 1-AU is "15" and the evaluation value of the lower car 1-AL is as shown in Table 3 of FIG. The evaluation value is "20", the evaluation value of the upper car 1-BU is "10",
It calculates that the evaluation value of the lower car 1-BL is “12”. Simultaneous response detecting means 7 is provided as a simultaneous response car corresponding to the registration of a new hall call on the sixth floor.
AU is detected, and the detection result is notified to the assignment control means 5.

On the other hand, the operation state detecting means 8 calculates the average unresponsive time in the past 5 minutes as 40 seconds, and determines the current state as the "congested" state based on this. Then, the determination result is notified to the assignment control means 5. Further, the operation mode management unit 12 notifies the assignment control unit 5 that the current operation mode is “semi-double operation”.

The assignment control means 5 includes a simultaneous response detection means 7
Car 1-A as a simultaneous response car based on the detection result of
When it is known that U exists, the evaluation value of the upper car 1-AU is input from the allocation evaluation calculating means 6, and is compared with the judgment value corresponding to the "congested" state under "semi-double operation". In this case, the allocation evaluation value of the upper car 1-AU is “15”, and the determination value corresponding to the “congested” state is “35”. That is, since the evaluation value: “15” <the judgment value: “35”, even if the upper car 1-AU of the car A is assigned to the new hall call registration on the 6th floor, it does not enter the long waiting state. Therefore, the assignment control means 5 sets the upper car 1-
It is decided to assign the AU to a new hall call registration on the 6th floor.

According to the seventh embodiment, when the operation control of the double-deck elevator is performed, the priority assignment control can be performed by using the judgment values according to the situation of both the traffic demand and the operation mode of the elevator. It becomes possible.

Next, an eighth embodiment of the present invention will be described. In this embodiment, in operation control of a double-deck elevator, a driving system is actively switched for the purpose of enhancing the operation efficiency of the elevator. Since the configuration of the eighth embodiment is almost the same as that of the seventh embodiment in FIG. 8, the eighth embodiment will be described with reference to FIG. However, in the eighth embodiment, the seventh
Unlike the embodiment, the operation mode management unit 12 receives the calculation result of the operation state detection unit 8.

That is, in this embodiment, when the vehicle is operating in a certain operation mode ("semi-double operation" or "single operation"), the operation state detecting means 8 operates within a predetermined time (for example, 30 minutes) in the past. The average value of the non-response time is calculated (provided that the judgment value has already been switched from the one corresponding to the "normal" state to the one corresponding to the "congested" state 30 minutes ago. ). Then, the driving method management means 12 determines that the average value is a predetermined value (for example, 4
(0 seconds) or more, the operation method is switched to improve the operation efficiency. In this case, if the current operation method is "semi-double operation", "double operation"
, And if the current operation mode is “single operation”, it is switched to “semi-double operation” or “double operation”.

For example, if "semi-double operation" is currently being performed and the average non-response time during the past 30 minutes is 50 seconds, the average value: 50 seconds> the predetermined value: 40 seconds. Means 12 switches the operation mode from "semi-double operation" to "double operation".

As described above, according to the eighth embodiment, in the operation control of the double deck elevator, if the operation efficiency of the elevator does not improve even if the determination value is changed, the operation efficiency is changed by switching the operation method. Can be improved.

FIG. 9 is a block diagram showing the configuration of the ninth embodiment of the present invention. In the above-described eighth embodiment, the driving method management unit 12 has a function of switching the driving method by itself. However, in the ninth embodiment, the switching operation is left to the elevator administrator. Is what you do. That is, the configuration of FIG. 9 is such that the operation method management means 12 in FIG. 8 is replaced with the operation method management means 12A, and the operation method switching notification means 13 and the operation method changeover switch 14 are added.

The operation mode management means 12A does not have a function of switching the operation mode by itself, but merely inputs the calculation result of the average value of the unresponsive times within the past predetermined time from the operation state detection means 8. However, it only outputs a warning signal indicating that the operation method should be switched based on this. Then, upon input of this caution signal, the driving mode switching notifying means 13 prompts the elevator manager to pay attention to switching the driving mode by screen display or voice output. When the elevator manager receives the notification from the driving method switching notifying means 13, the driver carefully checks the current driving condition and operates the driving method switch 14 to change the driving method of the double deck elevator. Switch.

According to the ninth embodiment, the switching of the driving method is ultimately entrusted to the elevator manager, so that even if the equipment is out of order, the wrong driving method is used. A situation in which the switching is automatically performed as it is can be prevented.

FIG. 10 is a block diagram showing the configuration of the tenth embodiment of the present invention. In this embodiment, in the eighth or ninth embodiment, when the operation mode of the double deck elevator is switched or is to be switched, the elevator user is informed that the switching has been performed or that the switching will be performed in the future. An announcement is made for this.

That is, the configuration of FIG. 10 is different from the configuration of FIG. 8 in that the announcement device 15-AU, AL, BU, BL,
And landing announcement devices 16-1... N. For example, if "Semi-double operation" is currently being performed and this is switched to "Double operation", in "Semi-double operation", both the upper and lower cars except for the departure reference floor are placed on any floor. Although it was possible to land, in the "double operation", the lower car can only land on odd-numbered floors, and the upper car can only land on even-numbered floors. According to the present embodiment, by promptly announcing such information to the user, it is possible to draw the user's attention and prevent unnecessary confusion. Although the configuration in FIG. 10 shows a configuration in which each announcement device is added to the configuration in FIG. 8, it is needless to say that a similar announcement device can be added to the configuration in FIG.

FIG. 11 is a block diagram showing the configuration of the eleventh embodiment of the present invention. In the tenth embodiment, when the driving system is switched or when the driving system is to be switched, the fact is announced. However, in the eleventh embodiment, the fact is indicated by the display device. This is to inform the user.

That is, the configuration of FIG. 11 is obtained by adding the in-car display device 17-AU, AL, BU, BL and the hall display devices 18-1... N to the configuration of FIG. According to the eleventh embodiment, it is possible to promptly display to the user that the driving mode has been switched, and to alert the user as in the tenth embodiment and to uselessly. You can avoid confusion. FIG.
Although the configuration 1 shows a configuration in which only each display device is installed, it is of course possible to add each announcement device in FIG. 10 in addition to these display devices.
