Abstract
Description
[Technical field]
[0001] The present disclosure relates to an opening / closing control device and a vehicle. [Background technology]
[0002] It is known that a battery is mounted on a vehicle that can operate with electricity. The battery supplies power to a load by closing a relay (opening / closing unit) provided in a power supply path of the battery.
[0003] Such a switching unit is opened when a command to stop power supply to the load is received, and is closed when a command to start power supply to the load is received. For example, Patent Document 1 discloses a configuration in which the switching unit is changed from the closed state to the open state when the current value of the power line becomes smaller than a predetermined current value after a command to stop power supply is received. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 6479247 Summary of the Invention [Problem to be solved by the invention]
[0005] In some cases, a vehicle may repeatedly stop and move in a short period of time. In this case, the opening / closing unit repeatedly switches between open and closed in a short period of time. Since the life of the opening / closing unit is determined according to the total number of times the opening / closing is performed and the current value applied during the switching operation between open and closed, there is a risk that the total number of times the opening / closing unit is opened and closed will reach the end of its life early due to the switching operation being performed repeatedly in a short period of time.
[0006] An object of the present disclosure is to provide an opening / closing control device and a vehicle that can prevent the total number of openings and closings of an opening / closing section from reaching the end of its life early. [Means for solving the problem]

Effect of the Invention
[0009] According to the present disclosure, it is possible to prevent the total number of times the opening and closing part is opened and closed from reaching the end of its life early. [Brief description of the drawings]
[0010] [Figure 1] 1 is a diagram showing a vehicle equipped with an opening / closing control device according to an embodiment of the present disclosure; [Diagram 2] 4 is a flowchart showing an example of opening and closing control operation in the opening and closing control device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 1 is a diagram showing a vehicle equipped with an opening / closing control device according to an embodiment of the present disclosure.
[0012] As shown in Fig. 1, vehicle 1 is a vehicle capable of running on battery 31, such as an electric vehicle or a hybrid vehicle. Vehicle 1 has load 2 capable of operating on electric power, such as a motor, a plurality of battery devices 3, and opening / closing controller 100. In vehicle 1, opening / closing controller 100 performs control to prevent the total number of openings and closings of opening / closing section 32, which will be described later, from reaching the end of its life prematurely.
[0013] The plurality of battery devices 3 are connected in parallel and configured to be capable of supplying power to the load 2. Each battery device 3 has the same configuration and includes a battery 31 and an opening / closing unit 32.
[0014] The battery 31 is configured to be able to supply power to the load 2 by connecting both positive and negative terminals to a power supply path connected to the load 2.
[0015] The opening / closing unit 32 is, for example, a relay that opens / closes the power supply path of the battery 31, and one is provided on each of the power supply paths on the positive and negative sides of the battery 31.
[0016] When the opening / closing unit 32 is in the closed state, power can be supplied from the battery 31 to the load 2 via the power supply path. When the opening / closing unit 32 is in the open state, the power supply path is cut off, and power is no longer supplied from the battery 31 to the load 2.
[0017] Opening and closing controller 100 includes a central processing unit (CPU), read only memory (ROM), random access memory (RAM), and input / output circuits (not shown). The CPU reads out programs stored in the ROM and executes the functions of measurement section 110, control section 120, and setting section 130. Opening and closing controller 100 can obtain, for example, a key-on command (power supply start command) and a key-off command (power supply stop command) from the driver of vehicle 1, and controls the open / closed state of opening and closing section 32 of each battery device 3 based on these commands.
[0018] Specifically, when a power supply start command is received, switching controller 100 closes switching unit 32, and when a power supply stop command is received, switching controller 100 opens switching unit 32. Switching controller 100 has a measurement unit 110, a control unit 120, and a setting unit 130.
[0019] When a command to stop the power supply to the load 2 is issued while the battery 31 is supplying power to the load 2, the measurement unit 110 measures the elapsed time from the command to stop the power supply. For example, the measurement unit 110 may be a timer device.
[0020] The control unit 120 acquires information about the elapsed time measured by the measurement unit 110, and maintains the opening / closing unit 32 in the closed state until the elapsed time becomes equal to or greater than the set time. In other words, the control unit 120 maintains the opening / closing unit 32 in the closed state when the elapsed time is less than the set time.
[0021] The setting unit 130 sets a set time for maintaining the opening / closing unit 32 in a closed state. The set time is the time from when the driver stops the vehicle 1 until when the driver starts driving the vehicle 1 again, and may be a time within which the driver can run a short errand. The set time is, for example, 10 minutes. The set time is a time that can be set by the driver (user). The driver sets the set time by operating an operating member of the vehicle 1. The set time may be set by an administrator who manages the vehicle 1. The set time may also be a fixed value that is preset when the vehicle 1 is manufactured.
[0022] Examples of short errands include the driver purchasing food and drink to eat in the vehicle, the driver unloading luggage loaded in vehicle 1 from vehicle 1 and delivering the luggage to a delivery destination, the driver receiving luggage from a person at a parked location and loading it into vehicle 1, the driver loading an object that is at a parked location into vehicle 1, etc.
[0023] Furthermore, when the elapsed time is equal to or greater than the set time and a power supply start command has not been acquired, the control unit 120 opens the opening / closing unit 32 .
[0024] In this way, the opening / closing unit 32 remains closed until the set time has elapsed since the power supply stop command. As a result, even if the driver turns the key off for a short errand and then turns the key on relatively soon after, the opening / closing unit 32 does not switch between the open state and the closed state. As a result, the number of times the opening / closing unit 32 is opened and closed does not change, so that the total number of times the opening / closing unit 32 is opened and closed can be prevented from reaching the end of its life.
[0025] Furthermore, when there is a command to start power supply to the load 2, the control unit 120 places the opening / closing unit 32 in a closed state. Specifically, when there is a command to start power supply when the opening / closing unit 32 is in an open state, the control unit 120 switches the opening / closing unit 32 from an open state to a closed state. Furthermore, when there is a command to start power supply when the opening / closing unit 32 is in a closed state and a set time has not yet elapsed since the command to stop power supply, the control unit 120 keeps the opening / closing unit 32 in the closed state.
[0026] As a result, the opening / closing unit 32 is switched only when necessary, thereby preventing the opening / closing unit 32 from being opened or closed unnecessarily.
[0027] An example of switching control operation in the switching controller 100 configured as above will be described below. Figure 2 is a flowchart showing an example of switching control operation in the switching controller 100. The process in Figure 2 is executed as appropriate when a power supply stop command is received, for example, when the switching unit 32 is in the open state.
[0028] 2, the opening and closing controller 100 determines whether or not a set time has elapsed (step S101). If the determination result shows that the set time has elapsed (step S101, YES), the opening and closing controller 100 switches the opening and closing section 32 to an open state (step S102).
[0029] On the other hand, if the set time has not elapsed (step S101, NO), the opening and closing controller 100 maintains the opening and closing section 32 in the closed state (step S103).
[0030] After step S102 or step S103, this control ends. Note that after the processing of step S103, the processing may return to the processing of step S101. Furthermore, after step S102 or step S103, if there is a command to start power supply, the switching controller 100 may set the switching section 32 to a closed state.
[0031] According to the present embodiment configured as described above, the opening / closing unit 32 is not switched between the open state and the closed state until the set time has elapsed since the power supply stop command.
[0032] For example, when the vehicle 1 is a vehicle used for delivering luggage or the like, the driver may repeatedly perform a series of actions, such as stopping the vehicle, delivering the luggage to the delivery destination, and immediately returning to the vehicle 1 to start driving the vehicle 1 again. Since such a series of actions is performed in a short period of time, if the opening / closing unit 32 is switched every time such an action is performed, there is a risk that the total number of times the opening / closing unit 32 is opened and closed will easily reach the end of its life.
[0033] In this embodiment, even if the driver turns the key off and then turns the key on quickly for such a short errand, the opening / closing unit 32 does not switch between the open state and the closed state. As a result, the number of times the opening / closing unit 32 is opened and closed does not change, so that the total number of times the opening / closing unit 32 is opened and closed can be prevented from reaching the end of its life.
[0034] In addition, when a command is issued to start supplying power to the load 2, the opening / closing unit 32 is closed, so that the opening / closing unit 32 is switched only when necessary. As a result, unnecessary opening and closing of the opening / closing unit 32 can be suppressed.
[0035] Furthermore, the measurement unit 110 may reset the elapsed time as soon as a power supply start command is received.
[0036] In the above embodiment, the control unit opens the opening / closing unit 32 when the elapsed time is equal to or greater than the set time and the power supply start command has not been received, but the present disclosure is not limited to this. For example, when the elapsed time is equal to or greater than the set time, the control unit may open the opening / closing unit regardless of the value of the current flowing through the power supply path.
[0037] In addition, in the above embodiment, a setting unit is provided, but the present disclosure is not limited to this. For example, if the set time is a preset value, the setting unit does not need to be provided.
[0038] Further, in the above embodiment, three battery devices 3 are mounted on the vehicle 1, but the present disclosure is not limited to this, and the vehicle may be configured to have one or two battery devices mounted on it, or may be configured to have four or more battery devices mounted on it.
[0039] Further, in the above embodiment, opening and closing control device 100 is provided in vehicle 1, however, the present disclosure is not limited to this, and may be a device separate from vehicle 1 (for example, a mobile terminal, a server, etc.).
[0040] In addition, the above-mentioned embodiments are merely examples of the embodiment of the present disclosure, and the technical scope of the present disclosure should not be interpreted as being limited by them. In other words, the present disclosure can be embodied in various forms without departing from the gist or main features thereof. [Industrial Applicability]
[0041] The opening / closing control device of the present disclosure is useful as an opening / closing control device and a vehicle that can prevent the total number of openings and closings of an opening / closing section from reaching the end of its life early. [Explanation of symbols]
