Further, the speed detection sensor 26 is not necessary when the energy supply unit 7 is fixedly installed as shown in FIG.

Hereinafter, each embodiment of the energy transfer device of the present invention applied to the above-described system will be described.

First, at the time of energy transfer, the moving objects 1, 10
An embodiment of an energy transfer device including a posture control means for controlling the posture of the first embodiment will be described.

At the time of energy transfer, communication using the transceivers 4, 6, 104, and 106 is performed between the mobile unit 1 and 101 and the supply facility 2 and 102 in advance, so that energy transfer can be performed smoothly. Various kinds of information are exchanged as if they were performed. Thereafter, energy transfer is actually performed. At this time, the position of the moving bodies 1 and 101 is controlled by the position control means to a position suitable for energy transfer. In the present embodiment, the above-described vehicle height adjustment EC
A vehicle height adjusting mechanism including the U17 and the suspension internal pressure adjusting valve 24 functions as the attitude control means.

The moving bodies 1 and 10 are controlled by the vehicle height adjusting mechanism.
1 for controlling the vehicle height (posture) of the moving body 1, 1 with respect to the position of the energy supply units 7, 107 on the side of the supply equipment 2, 102.
The position of the energy acquisition units 5 and 105 on the 01 side is changed. In the case as shown in FIG. 1 and the like, the energy transfer efficiency changes depending on the distance between the energy supply unit 7 and the energy acquisition unit 5. For this reason, the optimal vehicle height is calculated by the energy transfer ECU 11 at the time of energy transfer, and the vehicle height of the moving body 1 is adjusted by controlling the suspension internal pressure adjusting valve 24 via the vehicle height adjusting ECU 17.

Also in the case shown in FIG. 2, in order to make the energy supply unit 7 and the energy acquisition unit 5 surely contact with each other,
The optimal vehicle height is calculated by the energy transfer ECU 11 at the time of energy transfer, and the suspension internal pressure adjusting valve 24 is controlled via the vehicle height adjusting ECU 17 to control the moving body 1.
Adjust the height of the car.

Further, in the case shown in FIG.
1 side supply port (energy acquisition unit 105) and supply equipment 1
02 side arm part 107a (energy supply part 107)
The vehicle height is adjusted by the energy transfer ECU 11 to adjust the vehicle height of the moving body 1 by controlling the suspension internal pressure adjusting valve 24 via the vehicle height adjusting ECU 17 in order to match the vehicle height. As described above, by controlling the attitude of the moving bodies 1 and 101 and changing the positions of the energy acquisition units 5 and 105, energy transfer can be performed smoothly.

In the above-described example, the position of the energy acquisition unit is changed by the attitude control means. However, the posture control unit may control the posture of the moving body such that the posture of the moving body becomes the optimum posture for energy transfer regardless of whether the position of the energy acquisition unit is changed. For example, when transferring energy, it is preferable to keep the posture of the moving body constant. Therefore, the posture of the moving body may be controlled to suppress pitching, rolling, and yawing of the moving body. Or,
When the liquid fuel is supplied from the supply facility to the moving body and stored in the fuel tank in the moving body, there may be a case where the posture of the moving body is to be positively inclined due to the piping inside the moving body.

Such a case can be dealt with by realizing a so-called active suspension mechanism in which the suspension for each wheel is independently controlled by utilizing the above-described vehicle height adjustment mechanism. As described above, by controlling the posture of the moving body by the posture control means, it is possible to smoothly transfer energy.

Next, at the time of energy transfer, the moving objects 1, 10
An embodiment of an energy transfer device including a notifying unit for notifying one passenger that energy is being supplied will be described.

As described above, when the energy is exchanged, the mobile unit 101 and the supply facilities 2, 10
The two sides communicate with each other using the transceivers 4, 6, 104, and 106, and exchange various kinds of information so that energy can be smoothly exchanged. After that, the energy is actually transferred. Here, when the energy is transferred, the notifying unit notifies the occupant of the mobile 1, 101, in particular, the driver that the energy is being supplied. In the present embodiment, the above-described energy transfer ECU 11 and the indicator 13 connected thereto function as notification means.

In the present embodiment, communication is performed using the transceivers 4, 6, 104 and 106 even when the transfer of energy is started, and information indicating that the transfer of energy has been started is exchanged. Alternatively, it is detected by the above-described current / voltage sensor (flow rate / pressure sensor) 12 that the transfer of energy has been started. As a result, the indicator 13 is turned on (flashes) based on a signal from the energy transfer ECU 11. Thus, the driver (passenger) can reliably recognize that energy is being supplied to the mobile units 1 and 101, and can perform appropriate driving and other measures when transferring energy. .

Next, at the time of energy transfer, the moving objects 1, 10
An embodiment of an energy transfer device provided with opening / closing control means for controlling opening / closing of a window (window) or a door (entrance door) will be described.

In this embodiment, as described above, the start of the energy transfer is determined by the energy transfer EC.
If detected by U11, the door lock motor 22 and the window opening / closing motor 2
3 is driven to close the window and lock the door lock. At the time of energy transfer, the passenger
01, which can minimize the effects of energy transfer. For example, when a magnetic flux is generated at the time of energy transfer, the influence of the magnetic flux can be suppressed, and when the transfer of energy is performed by supplying the liquid fuel, it is possible to prevent the liquid fuel droplets from entering the moving bodies 1 and 101.

The energy transfer is performed between the mobile unit 1 and 101.
It is unlikely that the door will be opened and closed during energy transfer because it is performed during the transfer of energy.However, by locking the door, the door is prevented from being opened and closed during energy transfer, which is more preferable for safety. Energy can be smoothly transferred as a state.

Next, at the time of energy transfer, the moving objects 1, 1
01 side energy acquisition units 5 and 105 and supply facilities 2 and 1
An embodiment of an energy transfer device including a distance control unit that controls a distance between the energy supply units 7 and 107 on the 02 side will be described.

In the transfer of energy, when the transfer of energy is performed in a non-contact state (as shown in FIG. 1), when the transfer of energy is performed in a contact state (as shown in FIGS. 2 and 3). Also, the distance between the energy acquisition units 5 and 105 on the moving bodies 1 and 101 and the energy supply units 7 and 107 on the supply facilities 2 and 102 affects the energy transfer efficiency. For this reason, in this embodiment, the distance control means controls the distance between the energy acquisition units 5 and 105 and the energy supply units 7 and 107, so that energy transfer can be performed efficiently and smoothly.

As the distance control means for controlling the distance between the energy acquisition units 5 and 105 and the energy supply units 7 and 107, various configurations can be adopted. For example, FIG.
In such a case, the above-described vehicle height adjustment mechanism serves as both attitude control means and distance control means. FIG.
In the case as shown in FIG.
The distance between the energy supply unit 107 and the moving body 101 is measured by the distance measurement sensor 25 mounted on each of the energy supply units 107 moving on the zero, and the length of the arm unit 107a is adjusted by expanding and contracting. The mechanism may be distance control means.

Alternatively, the energy acquisition units 5 and 105 attached to the moving bodies 1 and 101 can be moved with respect to the main bodies of the moving bodies 1 and 101, and the energy acquisition units 5 and 10 can be moved.
A mechanism for controlling the distance between the energy supply units 7 and 107 by moving the distance 5 toward and away from the energy supply units 107 and 107 may be constructed as distance control means. At this time, when it is necessary to coordinate the movement of the moving bodies 1 and 101 with the movement of the supply facilities 2 and 102 in order to control the distance between the energy acquisition units 5 and 105 and the energy supply units 7 and 107. Exchange information by communication between the two transceivers 4, 6, 104, 106. As described above, the energy acquisition units 5, 1 of the moving bodies 1, 101 are controlled by the distance control unit.
05 and energy supply units 7 and 10 of supply equipment 2 and 102
The transfer of energy can be performed smoothly and reliably by controlling the distance from the control unit 7.

Next, at the time of energy transfer, the moving objects 1, 10
An embodiment of an energy transfer device provided with speed control means for controlling the speed of the first embodiment will be described.

In the transfer of energy, in the case as shown in FIG. 1, the amount of energy obtained by the moving body 1 varies depending on the speed of the moving body 1. In the case as shown in FIG. 3, it is necessary to coordinate the speed of the moving body 101 with the speed of the energy supply unit 107 on the supply facility 102 side. As described above, in the transfer of energy, the speed of the moving bodies 1 and 101 is an important factor. Therefore, in the present embodiment, the speed of the moving bodies 1 and 101 is controlled by the speed control means for controlling the speed of the moving bodies 1 and 101 so that the transfer of energy can be performed smoothly and efficiently.

In this embodiment, the moving bodies 1 and 101
Is detected by a wheel speed sensor 21 attached to each wheel, and the wheel speed sensor 21 functions as a part of speed control means. In this embodiment, the output of the engine, which is an internal combustion engine, is adjusted to
In addition to controlling the speed of the vehicle 1, the speed of the moving bodies 1 and 101 is also controlled by braking the vehicle with a brake mechanism. That is, the above-described engine ECU 14 and the injector 1 connected thereto and capable of adjusting the output of the engine.

The CU 15 and the brake actuator connected thereto also function as speed control means.

The moving bodies 1, 1 are adjusted by adjusting the output of the engine.
In order to control the speed 01, the fuel injection amount from the injector 18 is changed, or the valve lift & timing control actuator 19 is controlled to change the opening / closing timing of the intake and exhaust valves of the engine and the valve lift amount. Can be considered. On the other hand, in order to control the speed of the moving bodies 1 and 101 by braking the moving bodies 1 and 101 by the brake mechanism, a brake actuator 20 such as a solenoid valve arranged on a brake pipe is controlled and transmitted to each wheel. It is conceivable to adjust the applied brake oil pressure. By controlling the speed of the moving bodies 1 and 101 in this way, the speed of the moving bodies 1 and 101 is controlled so as to be a speed suitable for transfer of energy.

Further, from the supply facilities 2, 102 side, the moving bodies 1, 101
It is also conceivable to detect the speed of the moving object 1, 101 and control the speed of the moving object 1, 101 using the transceivers 4, 6, 104, 106. Further, in the case as shown in FIG. 1, communication is performed when the transceivers 4 and 6 face each other, so that the communication status between the plurality of transceivers 6 on the supply facility 2 side and the transceiver 4 on the mobile unit 1 side. It is also possible to detect the speed of the moving body 1 by using the transceivers 4 and 6 to control the speed of the moving body 1.

In this case, a gasoline-powered vehicle or a hybrid vehicle using an internal combustion engine as a driving source has been described as an example. It is conceivable to control the speed of the moving body by adjusting the output of the electric motor serving as a source.

Next, an abnormality detecting means for detecting an abnormality in the energy transfer state by comparing the information on the energy detected on the mobile object 1 and the information on the energy detected on the supply equipment 2 and 102 side is provided. An embodiment of the energy transfer device will be described.

Here, as the above-mentioned abnormality detecting means,
Two examples of a case where the information to be compared is information related to the amount of transferred energy and a case where the information to be compared is information related to the type of energy will be described. However, the information on energy is not limited to these two examples. The information to be compared includes the transceivers 4, 6, 1 described above.
04, 106, and the determination as to whether or not there is an abnormality is made by the energy transfer ECU on the moving body 1, 101 side.
11 or the energy transfer ECU on the side of the supply equipment 2 or 102
8, 108. That is, these components function as a part of the abnormality detecting means.

When the abnormality of the energy transfer state is detected based on the amount of transfer of energy, the current / voltage sensor (flow rate / pressure sensor) 12 described above is used on the moving body 1 or 101 side.
To detect the amount of energy actually obtained. On the other hand, the energy supply units 7, 1
07, the amount of energy supplied from the supply equipment 2,102
The energy transfer ECUs 8, 108 on the side of the vehicle are aware.
Therefore, these energy transfer amounts are set to

8, 108). Here, the current / voltage sensor (flow rate / pressure sensor) 12 also functions as a part of the abnormality detection means. When there is a large difference between the energy transfer amount detected on the moving body 1 and 101 side and the energy transfer amount detected on the supply facility 2 and 102 side, it is considered that an abnormality such as energy leakage has occurred somewhere. Therefore, it is determined that an abnormality has occurred in the energy transfer state.

On the other hand, when detecting an abnormality in the energy transfer state based on the type of energy, it is conceivable that the abnormality is detected prior to the energy transfer. As described above, the moving bodies 1 and 101 and the supply facilities 2 and 102
Various information is exchanged prior to energy transfer. At this time, if there is a mismatch between the energy type requested by the moving bodies 1 and 101 and the energy type to be supplied by the supply facilities 2 and 102, it is detected that the energy transfer state is abnormal.

For example, there is a case where the supply facilities 2 and 102 are trying to supply liquid fuel when the moving bodies 1 and 101 want to obtain electric energy. Alternatively, a case in which regular gasoline is being supplied when high-octane gasoline is requested, or the type of DC / AC at the time of obtaining electric energy is determined by the mobile unit 101 side and the supply facilities 2, 1.
In the case where the energy transfer state is different from that on the 02 side, the energy transfer state is detected as abnormal. Further, the abnormality may be detected not only when the abnormality is detected prior to the transfer of the energy, but also during or after the transfer of the energy.

Next, a description will be given of an embodiment of an energy transfer device provided with an abnormality detecting means for detecting an abnormality based on the relative speed of the moving bodies 1 and 101 with respect to the supply equipment 2 and 102 in the energy transfer state.

When energy is supplied to the moving bodies 1 and 101 during movement, in the case as shown in FIG. 1, the moving body 1 is moved at a relative speed with respect to the supply equipment 2 (the energy supply section 7 thereof). It has already been mentioned that the amount of energy acquired by 1 varies. However, in the case shown in FIG.
Since the supply equipment 2 does not move, the relative speed of the mobile 1 to the supply equipment 2 is the speed of the mobile 1 itself. FIG.
In such a case as shown in (1), it is necessary to coordinate the speed of the moving body 101 and the speed of the energy supply unit 7 of the supply facility 2, and the
As mentioned above, it is not possible to transfer energy reliably if the speed relative to is large.

Therefore, in this embodiment, the abnormality detecting means detects an abnormality in the energy transfer state based on the relative speed of the moving body 1 to the supply equipment 2. here,
In addition to the transceivers 4, 6, 104, 106,
01-side energy transfer ECU 11, wheel speed sensor 2
1, the supply equipment 2, the energy transfer ECU 8 on the 102 side,
The relative speed of the moving body 1 to the supply facility 2 is detected by the speed detection sensor 108 and the like. Then, based on the detected relative speed, the energy transfer ECU 1
1 or the energy transfer ECUs 8 and 108 detect whether or not the energy transfer state is abnormal. That is,
These components function as abnormality detection means.

Note that the supply facilities 2, 1
It is also possible to provide a millimeter-wave radar sensor, a laser radar sensor, or the like on the side of the supply equipment 2, 102 so as to detect the relative speed with respect to the sensor 02 (the distance measurement sensor 25 is diverted). You can also). In addition, in the case shown in FIG. 1, communication is performed when the transceivers 4 and 6 face each other. Therefore, the communication status between the plurality of transceivers 6 on the supply facility 2 side and the transceiver 4 on the mobile unit 1 side. The speed of the moving body 1 can also be detected from.

Next, a description will be given of an embodiment of an energy transfer apparatus provided with an abnormality detecting means for detecting an abnormality based on the relative position of the moving bodies 1 and 101 with respect to the supply equipment 2 and 102 in the energy transfer state.

When energy is supplied to the moving bodies 1 and 101 during movement, as in the case of the above-described relative speed,
An important requirement is the relative position of the moving body 1 with respect to (the energy supply unit 7 of) the supply facility 2. For example, in the case as shown in FIG. 3, energy is exchanged in a state where the position of the mobile unit 101 and the position of the energy supply unit 7 of the supply unit 2 are synchronized with each other. The relative position with respect to (the energy supply unit 7) is important.

Therefore, in the present embodiment, the abnormality detecting means detects an abnormality in the energy transfer state based on the relative position of the moving body 1 to the supply equipment 2. here,
By using the distance measuring sensor 25, the relative position of the moving body 1 with respect to the supply equipment 2 is detected. Then, based on the detected relative position, the energy transfer ECU 11
Alternatively, the energy transfer ECUs 8 and 108 detect whether the energy transfer state is abnormal. That is, these configurations function as abnormality detection means.

The supply facilities 2, 1 for the moving bodies 1, 101
The detection of the relative position with respect to
It is also possible to carry out detection by mounting a PS unit or the like. Further, in the case as shown in FIG.
Since the communication is performed when the mobile telephones 6 face each other, the position of the mobile unit 1 can be detected from the communication status between the plurality of transceivers 6 on the supply facility 2 side and the transceiver 4 on the mobile unit 1 side.

As in some of the above-described examples, the abnormal state at the time of energy transfer can be detected by the abnormality detecting means, so that the abnormality at the time of energy transfer can be promptly dealt with.

The energy transfer device of the present invention is not limited to the above embodiment. For example, each energy transfer device of the present invention constitutes one device on the moving body side and the supply facility side when completed as one device only on the moving body side, or when completed as one device only on the supply facility side. It can take various forms such as cases.
Further, each energy transfer device of the present invention is applicable not only to the case where the moving object is an automobile running on a road network as in the above-described embodiment, but also to various moving objects.
