Description

TECHNICAL FIELD The present disclosure relates to vehicles capable of carrying electrically powered bodywork.

2. Description of the Related Art Among vehicles such as trucks, vehicles equipped with a variety of multi-purpose devices (hereinafter referred to as mounted objects) have become widespread. Conventionally, many mounted objects operate by obtaining power from an internal combustion engine of a vehicle via a PTO (power take-off) mechanism or the like. However, in recent years, electric mounted objects that operate on electric power have been developed, and vehicles in which electric power is supplied to the electric mounted objects from a battery of the vehicle are becoming popular.

Patent Literature 1 discloses a detachable container refrigerating vehicle having a vehicle and a detachable refrigerating container. In Patent Literature 1, the inside of a refrigerated container is cooled by electric power supplied from a power supply device mounted on a vehicle.

There is a demand to improve the convenience of a vehicle by appropriately replacing various mounted objects. However, the technology disclosed in Patent Literature 1 makes refrigerating containers detachable from each other, and does not assume that multiple types of mounted objects are replaced with each other. Specifically, in the technology disclosed in Patent Document 1, it is not assumed that the refrigerated container is transferred to, for example, a packer device for garbage trucks (garbage trucks).

Different types of mounted objects require different power supply control on the vehicle side according to the type of mounted object. Specific examples of different power supply control are as follows. That is, when the mounted object is, for example, a refrigerated container, the vehicle must always continue to supply power to the refrigerated container so as not to increase the temperature inside the container. On the other hand, if the mounted object is, for example, a packer device, the vehicle needs to supply power only when requested by the packer device. However, for safety reasons, the vehicle must be stopped when the packer device operates. must be determined before power supply is started.

SUMMARY OF THE INVENTION In view of such circumstances, it is an object of the present invention to provide a vehicle in which various mounted objects can be remounted as appropriate and power can be appropriately supplied to the mounted mounted objects. .

A vehicle according to an aspect of the present disclosure includes a vehicle body frame on which a mounted object is mounted, a battery, a vehicle-side connector connected to a mounted object-side connector provided on the mounted object, and the mounted object. and an identification unit for identifying the type of the vehicle-side connector for each type of the vehicle-mounted object when the vehicle-side connector is connected to the vehicle-side connector and receives a request signal requesting power supply from the vehicle-mounted object.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In addition, the embodiment described below is an example, and the present disclosure is not limited to this embodiment.

FIG. 1 is a diagram for explaining vehicle 100 according to an embodiment of the present invention. FIG. 1 is a conceptual diagram of a vehicle 100 viewed from the side. Vehicle 100 according to the embodiment of the present invention is a truck. As shown in FIG. 1 , vehicle 100 has cab 101 , body frame 102 , wheels (including front and rear wheels) 103 , and vehicle-side connector 104 .

A cab 101 is a portion where a driver's seat is provided. Under the cab 101, a motor 105 (see FIG. 3 described later) that rotates the wheels 103, a control unit 110 that controls the entire vehicle 100 (see FIG. 3 described later), and the like are provided.

A vehicle body frame 102 extends behind the cab 101 . A mounting object 200 (see FIGS. 2A, 2B, and 3), which will be described later, is mounted on the vehicle body frame 102 . Vehicle body frame 102 is provided with vehicle-side connector 104 for electrical connection with mounted object 200 . Although not shown, the body frame 102 is provided with a fixing mechanism for fixing the mounted object 200 to the body frame 102 .

FIG. 2A is a diagram for explaining how the vehicle 100 is mounted with the mounted object 200. FIG. FIG. 2B is a diagram for explaining how the vehicle 100 is mounted with the mounted object 200 . 2A and 2B show, as an example, a state in which the box-shaped mounting 200 is (or was) mounted on the vehicle 100, but in the present invention, the shape of the mounting 200 is not limited to this. is not limited to

In the example shown in FIG. 2A , the mounted object 200 is positioned and lowered from the upper side of the vehicle body frame 102 while the vehicle 100 is stopped. The holding and movement of the mounted object 200 in the example shown in FIG. 2A may be performed by a crane or the like (not shown) provided outside the vehicle 100, for example. Further, the alignment of the mounted object 200 with respect to the vehicle 100 (body frame 102) may be performed by, for example, a guide device (not shown).

By aligning the mounting object 200, when the mounting object 200 is lowered onto the vehicle body frame 102, the vehicle side connector 104 and the mounting object side connector, which is a connector provided on the side of the mounting object 200, are connected. 201 are connected to each other.

As shown in FIG. 2B , the mounted object 200 is fixed to the vehicle body frame 102 by a fixing mechanism (not shown) while the mounted object 200 is placed on the vehicle body frame 102 . As a result, the mounted object 200 is mounted on the vehicle 100 . In this state, the vehicle-side connector 104 and the mounted object-side connector 201 are connected to each other as described above.

FIG. 3 is a block diagram showing the configuration of the vehicle 100 and the mounted object 200 mounted on the vehicle 100. As shown in FIG. As shown in FIG. 3 , vehicle 100 further includes motor 105 , battery 106 , control unit 110 , and memory 120 . Moreover, as shown in FIG.

The motor 105 rotates the wheels 103 using power stored in the battery 106 under the control of the control unit 110 . Thereby, the vehicle 100 runs. That is, in the present embodiment, vehicle 100 is an electric vehicle.

The vehicle-side connector 104 is connected to the mounted object-side connector 201 of the mounted object 200 when the mounted object 200 is mounted on the vehicle 100 as described above. The vehicle-side connector 104 and the mounted object-side connector 201 each have a connection terminal, and the terminals are maintained in contact with each other, whereby the vehicle-side connector 104 and the mounted object-side connector 201 are electrically connected. It will be in a connected state. As a result, electric signals containing various information can be transmitted and received between the control unit 110 of the vehicle 100 and the electric device 202 of the mounted object 200, and electric power can be transferred from the battery 106 to the electric device 202. supply becomes possible.

Control unit 110 controls vehicle 100 . The control unit 110 is, for example, an ECU (Electronic Control Unit). In the present embodiment, as shown in FIG. 3 , control unit 110 has motor control unit 111 , identification unit 112 , power supply determination unit 113 , and power supply control unit 114 .

The motor control unit 111 supplies electric power from the battery 106 to the motor 105 to rotate the motor 105 at a desired speed based on a driver's input operation to an operating device such as an accelerator pedal (not shown). As a result, the vehicle 100 runs at a speed corresponding to the input operation.

The identifying unit 112 identifies the type of the mounted object 200 based on the identification information received from the mounted object 200 when the mounted object side connector 201 is connected to the vehicle side connector 104 . In the present embodiment, it is assumed that various types of mountings 200 are attachable to and detachable from the vehicle 100 . In the present invention, the type of the mounted object 200 is not particularly limited. Mountings used for various specially equipped vehicles such as fire trucks are mentioned.

In addition, the identification unit 112 reads from the memory 120 the determination criterion information corresponding to the type of the identified mounted object 200 . This determination criterion information is used when determining whether or not to supply power to the mounted object 200 by the power supply determination unit 113, which will be described later.

When receiving a request signal requesting power supply from the mounted object 200 in a state where the mounted object side connector 201 is connected to the vehicle side connector 104, the electric power supply determination unit 113 determines based on the judgment reference information. to determine whether or not to supply power. The details of the determination criteria information and determination processing by the power supply determination unit 113 will be described later.

When the power supply determination unit 113 determines that the power supply is to be performed, the power supply control unit 114 performs control to supply the requested power from the battery to the mounted object 200 . As a result, electric power is supplied to the electric device 202 of the mounted object 200, and the electric device 202 operates. The electric device 202 is a power source for the mounted object 200, and is, for example, an electric hydraulic pump (motor).

As described above, the electric device 202 operates with electric power supplied from the battery 106 of the vehicle 100, so that the mounted object 200 operates.

Below, processing of the control unit 110 when the vehicle 100 is mounted with the mounted object 200 will be described. First, FIG. 4 is a flowchart for explaining the identification processing executed by the control unit 110. As shown in FIG.

In step S<b>1 , the identifying unit 112 receives identification information for identifying the type of the mounted object 200 from the mounted object 200 side. The identification information is, as described above, information indicating the type of the mounted object 200, which is stored in a memory (not shown) of the mounted object 200, for example.

In step S2, the identification unit 112 identifies the type of the mounted object 200 based on the identification signal.

In step S<b>3 , the identification unit 112 reads from the memory 120 the determination criterion information corresponding to the type of the identified mounted object 200 .

In this way, when the vehicle 100 is mounted with the mounted object 200, the control unit 110 identifies the type of the mounted object 200 and acquires the judgment reference information corresponding to the type.

The identification process shown in FIG. 4 is executed when the vehicle 100 is mounted with the mounted object 200, and the judgment reference information read in step S3 is used until the mounted object 200 is removed from the vehicle 100. It is held in the control unit 110 .

When receiving a power supply request signal from the mounted object 200 in this state, the control unit 110 executes the following determination processing and power supply processing. FIG. 5 is a flowchart for explaining determination processing and power supply processing executed by control unit 110 .

In step S<b>11 , control unit 110 determines whether or not a request signal requesting power supply has been received from mounted object 200 . When determining that the request signal has been received (step S11: YES), the control unit 110 advances the process to step S12, otherwise (step S11: NO), repeats the process of step S11.

In step S12, the power supply determining unit 113 determines whether or not to supply power to the mounted object 200 based on the determination criterion information read out in step S3 shown in FIG.

Below, the determination criterion information and the determination of the power supply determination unit 113 in step S12 will be described with specific examples.

6A and 6B are diagrams exemplifying tables showing judgment criteria information. FIG. 6A shows an example of judgment criteria when the mounted object 200 is a refrigeration system of a refrigerator truck, and FIG. 6B shows an example of judgment criteria when the mounted object 200 is a packer device of a garbage truck. each shown. As shown in FIGS. 6A and 6B, the criterion information may contain multiple items. In the example shown in FIGS. 6A and 6B, two items, "vehicle state" and "remaining battery capacity," are included as items, but in the present invention, more items are included in the criterion information. good too.

The item "vehicle state" indicates whether the vehicle 100 is running or stopped, whether the shift lever is in the parking range, in the drive range, whether the parking brake is operating, and so on. It is a judgment standard regarding the state.

If the mounted object 200 is a refrigerating device, the temperature inside the mounted object 200 must always be kept low. Therefore, as shown in FIG. 6A, the determination criteria are set so that electric power is supplied regardless of the vehicle state and the remaining battery level. That is, when the mounted object 200 is a refrigerating device, power is set to be supplied while the vehicle 100 is running or stopped. In addition to these judgment criteria shown in FIG. 6A, for example, even when the remaining battery power is about to run out, power supply to the mounted object 200 is prioritized over power supply to the motor 105. Criteria may be set.

On the other hand, if the mounted object 200 is a packer device, for safety reasons, power should not be supplied unless the vehicle 100 is stopped. For this reason, as shown in FIG. 6B, a criterion is set such that power is supplied only when the vehicle speed is 0 and the parking brake (not shown) is operating. Moreover, since the operation of the packer device is not urgent, priority should be given to power supply to the motor 105 when the battery level is low. For this reason, a criterion is set so that power is not supplied when the remaining battery charge is equal to or less than a predetermined threshold.

In this way, different judgment criteria are set in advance according to the type of the mounted object 200 and stored in the memory 120 . The power supply determination unit 113 determines whether or not to supply power to the mounted object 200 based on the determination criteria information indicating such determination criteria.

Returning to the description of FIG. In step S13, when it is determined to supply power as a result of the determination in step S12 (step S13: YES), the power supply determining unit 113 advances the process to step S14. On the other hand, when determining not to supply power (step S13: NO), the power supply determining unit 113 advances the process to step S17.

In step S<b>14 , the power supply control unit 114 supplies the requested power to the mounted object 200 . This causes the mounted object 200 to operate.

In step S15, the power supply determination unit 113 determines whether to continue power supply. This determination is always made while power is being supplied to the mounted object 200 in step S14. Also, this determination may be made based on the above-described determination criteria information. If it is determined to continue power supply (step S15: YES), the power supply determining unit 113 advances the process to step S16; otherwise (step S15: NO), the process returns to step S12.

The case in step S15 is otherwise, for example, when a request to stop the power supply is received from the side of the mounted object 200, or when the power supply cannot be continued due to circumstances on the side of the vehicle 100 (the remaining battery level is low). below the threshold value, or the battery becomes abnormally high temperature, etc.).

In step S<b>16 , the power supply control unit 114 continues power supply to the mounted object 200 . After that, the process returns to step S15.

On the other hand, in step S<b>17 , the power supply control unit 114 does not supply power to the mounted object 200 . Then, in step S18, control unit 110 transmits to mounted object 200 a power supply failure notification indicating that power cannot be supplied. The mounted object 200 that has received the power supply failure notification may display, for example, on a display unit (not shown) that power is not supplied. As a result, the operator who is trying to operate the mounted object 200 is notified that the mounted object 200 will not operate due to the lack of power supply. At this time, the control unit 110 may include information indicating the reason for not supplying power to the mounted object 200 in the power supply failure notification. In this case, the operator can know the reason why the mounted object 200 does not operate, and can take measures against the reason. After step S18, the process returns to step S12.

As described above, the power supply determination unit 113 determines whether or not to supply power to the mounted object 200 is repeatedly executed while the mounted object 200 is mounted on the vehicle 100 . be. Therefore, even when power is being supplied, the power supply is stopped when the criterion for the mounted object 200 is no longer satisfied. Moreover, even in a state where power supply is not performed because the criterion is not satisfied, power supply is started when the criterion is satisfied. Also, when the control unit 110 receives a request to stop the power supply from the mounted object 200, the power supply is stopped.

With such a configuration, the power supply determination unit 113 repeatedly determines whether or not to supply power to the mounted object 200 while the mounted object 200 is mounted on the vehicle 100 . be. Therefore, even when power is being supplied, the power supply is stopped when the criterion for the mounted object 200 is no longer satisfied. Moreover, even in a state where power supply is not performed because the criterion is not satisfied, power supply is started when the criterion is satisfied. Also, when the control unit 110 receives a request to stop the power supply from the mounted object 200, the power supply is stopped. Therefore, appropriate power supply can be performed based on the type of the mounted object 200 mounted on the vehicle 100 .
