  The present invention is to upload vehicle position information to a server so that the server manages the vehicle position information, facilitates management of the vehicle by the administrator, and allows the user to be notified of the parking position. The present invention relates to a wireless terminal and a vehicle position information transmission method.

Conventionally, a navigation device is mounted on a vehicle such as an automobile or a motorcycle, and the current position can be registered as a point of interest (POI) by a button operation or the like. When registering a location, it is also possible to register the position where the vehicle is parked, and by registering the parking position of the vehicle, the parking position set by the driver can be set as the destination at a later date. It was.
In Patent Document 1, as a device capable of automatically registering a POI at a position where a vehicle is parked, a position acquired by GPS (Global Positioning System) at the time when an ignition switch of an automobile is turned on. An apparatus for storing data is disclosed.

Japanese Patent Laid-Open No. 9-280881

In the technique disclosed in Patent Document 1, even if a configuration is provided in which the position of the vehicle is transmitted to the management server in order to record the vehicle position information when the ignition switch of the automobile is turned on, the management server It was only after the vehicle moved from the parking position that the parking position could be grasped.
However, it is generally necessary to memorize the location where the vehicle is parked, such as a commercial facility such as a large shopping center, a parking lot for an event venue such as a concert, and a parking lot such as a hospital or government office. The number of parking lots was very large. In other words, if you park a vehicle in such a parking lot, you may not be able to find your vehicle when you are finished and return to your vehicle, and you need to remember the parking position of your vehicle. It was.
In order to solve this problem, it is conceivable to provide a power source such as an independent battery in a device for storing position information. However, a decrease in capacity is a problem whether the battery is a primary battery or a secondary battery. Specifically, when the capacity is small, the location information parked after the ignition is turned off may not be transmitted to the management server.

  In the wireless terminal that transmits vehicle position information to the management server, when the remaining capacity of the battery unit is small, the latest vehicle position information is transmitted to the management server at short time intervals. An object of the present invention is to enable a management server to grasp parking position information of a vehicle.

When the capacity is equal to or less than the first capacity value, a position information notification unit (for example, a position information notification unit described later) notifies the vehicle position information to the server at a second transmission interval shorter than the first transmission interval. 208).

According to the wireless terminal of (1), the position information notification unit sends the vehicle position information to the server at a preset first transmission interval when it is determined that the remaining capacity of the battery unit exceeds the first capacity value. When the remaining capacity of the battery unit is less than or equal to the first capacity value, the vehicle position information is notified to the server at a second transmission interval shorter than the first transmission interval.
As a result, even when the remaining capacity of the battery unit is small, the latest vehicle position to be parked can be reliably transmitted to the server, and the latest vehicle parking position can be grasped on the server side. It becomes.

According to the wireless terminal of (2), the remaining capacity determination unit determines whether or not the remaining capacity of the battery unit exceeds the first capacity value when the vehicle activation state is on.
Accordingly, the position information notification unit transmits the vehicle position information to the server at the first transmission interval when the vehicle activation state is the on state, or the second transmission interval shorter than the first transmission interval. The vehicle position information can be transmitted to the server.

  (3) A wireless terminal (e.g., a wireless unit 24 to be described later) and a battery unit (for example, a battery unit 221 to be described later) connected to the server so as to be able to communicate with each other. For example, a vehicle position information transmission method by a wireless terminal 2) to be described later, wherein the vehicle position information transmission method is a positioning step in which the wireless terminal measures a vehicle position based on information from satellite radio waves (for example, A vehicle position measuring step described later), a power input step receiving power from an external power source (for example, power input controlling step described later), and a remaining capacity detecting step for detecting the remaining capacity of the battery unit (for example described later) Remaining capacity detecting step) and determining whether or not the remaining capacity of the battery unit detected by the remaining capacity detecting step exceeds a preset first capacity value. A first transmission interval that is set in advance when it is determined that the remaining capacity of the battery unit exceeds the first capacity value by a capacity determination step (for example, a remaining capacity determination step described later) and the remaining capacity determination step Vehicle position information is transmitted to the server, and when the remaining capacity of the battery unit is less than or equal to the first capacity value in the remaining capacity determination step, the second transmission interval shorter than the first transmission interval.

For example, when the atmospheric pressure at the parking position becomes higher than the atmospheric pressure at the time of traveling on the basis of the atmospheric pressure during traveling of the vehicle 1, it can be estimated that the vehicle has entered the underground parking lot from the road. On the contrary, when the atmospheric pressure at the parking position becomes lower than the atmospheric pressure at the time of traveling, it can be estimated that a high-rise building type multi-story parking lot has been entered from the road.
The sensor unit 21 is connected to the control unit 20 and performs measurement based on an instruction from the control unit 20.

The power supply unit 22 includes a battery unit 221. The power supply unit 22 can be connected to the vehicle 1. By doing so, the wireless terminal 2 can receive power from the vehicle 1. When the wireless terminal 2 receives power from the vehicle 1, the battery unit 221 is also charged.

When a start switch (hereinafter also referred to as “ignition switch”) that is an engine start or EV system start switch of the vehicle 1 is turned on, the wireless terminal 2 is supplied with electric power from the vehicle 1.
Conversely, when the ignition switch is turned off and the engine is stopped, the supply of electric power from the vehicle 1 is stopped. Then, the power supply to the wireless terminal 2 is switched from the supply from the vehicle 1 to the supply from the battery unit 221.
In this way, the wireless terminal 2 grasps whether the engine of the vehicle 1 is started (system is activated) or not (the ignition switch is turned on or off) depending on whether or not power is supplied from the vehicle 1. can do. That is, the wireless terminal 2 can detect the activation state of the vehicle based on whether or not power is supplied from the vehicle 1.

Specifically, the power supply unit 22 includes, for example, a voltage sensor (not shown), detects a power supply voltage output from the vehicle 1 (cigarette lighter socket), and detects a detection result (whether or not power is supplied from the vehicle 1). ) May be output to the control unit 20. By doing so, the control unit 20 (a startup switch information detection unit described later) determines whether or not the engine of the vehicle 1 is started (system is started) depending on whether or not power is supplied from the vehicle 1 (ignition). The switch is on or off).
In addition, the control unit 20 grasps the state (whether the ignition switch is on or off) whether the engine of the vehicle 1 is started (system is activated), thereby supplying power from the vehicle 1. The supply can be switched to the supply from the battery unit 221.

Note that the control unit 20 can acquire on / off information of an activation switch (ignition switch) from the vehicle 1 via the proximity wireless communication unit 241. That is, the control unit 20 can determine the off state of the start switch by obtaining information (start switch on / off information) describing the start switch on / off identifier from the vehicle 1. Moreover, the control part 20 can also perform the simple judgment which considers that a starting switch is turned off, when pairing (connection) with the vehicle 1 of the radio | wireless terminal 2 is cut | disconnected.

Next, the control unit 20 will be described in detail.
The control unit 20 is constituted by a microprocessor having a CPU, RAM, ROM, I / O and the like. The CPU executes each program read from the ROM or the storage unit 23, reads information from the RAM, ROM, and the storage unit 23 at the time of execution, and writes information to the RAM and the storage unit 23. Signals are exchanged with the sensor unit 21, the radio unit 24, the display unit 25, and the input unit 26.

The control unit 20 causes the wireless terminal 2 to function as predetermined means (hereinafter collectively referred to as “position information upload unit”) by executing each program (hereinafter also collectively referred to as “position information upload application”).
Further, the control unit 20 executes each program to give the wireless terminal 2 a predetermined procedure (hereinafter collectively referred to as “location information upload procedure”) or a predetermined step (hereinafter referred to as “location information upload step”). Execute).

  Hereinafter, functions of the control unit 20 will be described from the viewpoint of the position information upload unit. The description based on the viewpoint of the location information upload procedure (method) can be described by replacing “part” with “procedure” or “step”, and is therefore omitted.

  In order to reliably transmit the parking position of the vehicle 1 to the server 2 even when the remaining capacity of the battery unit 221 is small, the control unit 20 includes a start switch information detection unit 201, a power input control unit, as shown in FIG. 202, a vehicle position measurement unit 203, a remaining capacity detection unit 204, a remaining capacity determination unit 205, a first determination unit 206, an altitude calculation unit 207, and a position information notification unit 208.

The start switch information detection unit 201 detects the start state of the vehicle 1, that is, the state of whether the engine of the vehicle 1 is started (system is started) (the state where the ignition switch is on or off).
Specifically, as described above, the activation switch information detection unit 201 detects the vehicle 1 based on the power supply voltage output from the vehicle 1 (cigarette lighter socket) detected by a voltage sensor (not shown). It is possible to detect whether the engine is started (system is activated) or not (ignition switch is on or off).

Further, the activation switch information detection unit 201 acquires the on / off information of the activation switch (ignition switch) from the vehicle 1 via the proximity wireless communication unit 241, thereby starting the engine of the vehicle 1 (system activation). It is also possible to detect whether or not the ignition switch is on (the ignition switch is on or off).
The activation switch information detection unit 201 can also determine parking of the vehicle 1 from vibration of the vehicle body using the gravity sensor 212.

When the activation switch information detection unit 201 detects that the engine of the vehicle 1 is started (system is activated), the power input control unit 202 controls to receive power from the vehicle 1 (cigarette lighter socket). To do. At this time, the power input control unit 202 may charge the battery unit 221.
The power input control unit 202 supplies power when the start switch information detection unit 201 detects that the start state of the vehicle 1 is off, that is, the engine of the vehicle 1 is stopped (system is stopped). Control is performed to receive from the battery unit 221.

  The vehicle position measurement unit 203 records the current position information (latitude, longitude, and positioning time) of the wireless terminal 2 measured by the GPS sensor 211 in the storage unit 23 as vehicle position information for each preset period. .

The remaining capacity detection unit 204 detects the remaining capacity of the battery unit 221 included in the power supply unit 22 by a known means (method).
Specifically, the remaining capacity detecting unit 204 integrates the charging current and the discharging current every predetermined period based on the charging current and the discharging current of the battery unit 221 detected by a current sensor (not shown), for example. Then, the accumulated charge amount and the accumulated discharge amount are calculated, and the remaining capacity of the battery unit 221 is detected by adding or subtracting these accumulated charge amount and accumulated discharge amount to the initial capacity or the remaining capacity immediately before the start of charge / discharge. be able to.
Further, the remaining capacity detection unit 204 may detect the remaining capacity of the battery unit 221 based on, for example, a characteristic map regarding the remaining capacity and the voltage value between the terminal voltages.

The remaining capacity determination unit 205 determines whether or not the remaining capacity of the battery unit 221 detected by the remaining capacity detection unit 204 exceeds a preset first capacity value.
More specifically, the remaining capacity determination unit 205 is detected by the remaining capacity detection unit 204 when the activation state of the vehicle 1 is detected by the activation switch information detection unit 201. It is determined whether the remaining capacity is greater than the first capacity value or less than the first capacity value.

The first determination unit 206 determines whether or not the vehicle position information can be measured by the GPS sensor 211 when the activation state of the vehicle 1 is detected by the activation switch information detection unit 201 to be an off state.
Specifically, the first determination unit 206 determines that the vehicle position information can be measured when the position where the vehicle 1 is parked is at a position where the GPS satellite 211 can receive a GPS satellite signal.
On the other hand, when the position where the vehicle 1 is parked is a position where the GPS sensor 211 cannot receive a GPS satellite signal, for example, in the case of a three-dimensional parking lot such as a building or an underground parking lot of a facility, the first determination unit 206 determines that the vehicle position information cannot be measured.

When the altitude calculation unit 207 is based on the change in the atmospheric pressure measured by the atmospheric pressure sensor 213 and the atmospheric pressure of the vehicle 1 is higher than the atmospheric pressure during traveling, for example, From the road, it can be determined that you have entered the basement at a low altitude. On the other hand, when the atmospheric pressure of the vehicle 1 becomes lower than the atmospheric pressure during traveling, it can be determined that the vehicle 1 has entered a place with a high elevation (for example, a three-dimensional parking lot such as a building) from the road.
The altitude calculation unit 207 can be configured to calculate the underground level or the ground level based on the altitude difference from the road.

[Location information notifying unit 208]
<When the starting state of the vehicle 1 is on>
When the activation state of the vehicle 1 is detected by the activation switch information detection unit 201, that is, the position information notification unit 208 detects that the engine of the vehicle 1 is started (system is activated), the vehicle position measurement unit 208 The current position information (latitude, longitude, and positioning time) of the wireless terminal 2 stored in the storage unit 23 by 203 is notified to the management server 3 via the wireless unit 24 as vehicle position information. In this case, the wireless terminal 2 notifies the management server 3 with the power supplied from the vehicle 1.

The position information notification unit 208 controls the timing for notifying the management server 3 of the vehicle position information via the wireless unit 24 based on the remaining capacity of the battery unit 221 detected by the remaining capacity detection unit 204.
The position information notification unit 208 transmits the vehicle position information stored in the storage unit 23 periodically or non-periodically to the wireless unit 24 when the activation state of the vehicle is detected by the activation switch information detection unit 201. To the management server 3.

Specifically, when the position information notification unit 208 determines that the remaining capacity of the battery unit 221 detected by the remaining capacity detection unit 204 exceeds a preset first capacity value, The vehicle position information is transmitted to the management server 3 at a transmission interval of 1. In addition, when the position information notification unit 208 determines that the remaining capacity of the battery unit 221 detected by the remaining capacity detection unit 204 is equal to or less than the first capacity value set in advance, the position information notification unit 208 is more than the first transmission interval. The vehicle position information is notified to the management server 3 at a short second transmission interval. Here, the first capacity value may be set such that, for example, the remaining capacity of the battery unit 221 is 20%, the first transmission interval is, for example, 5 minutes, and the second transmission interval is, for example, 1 minute.
By doing so, the ignition switch is turned off, the power supply to the wireless terminal 2 is switched from the vehicle 1 to the battery unit 221, and the remaining capacity of the battery unit 221 is small. Even when transmission to the vehicle 3 is not possible, it is possible to secure vehicle position information relatively close to the parked vehicle position by shortening the transmission interval of the vehicle position information to the management server 3 before the engine stops. .

Here, it is desirable that the values of the first capacity value, the first transmission interval, and the second transmission interval are appropriately adjusted to optimum values by the practitioner. As an administrator or user, it is ideal to grasp the vehicle position in real time, but in that case, the vehicle position must always be measured and transmitted to the management server. This imposes pressure on the communication band of the wireless communication network, and causes a huge communication charge to the user, which is not realistic.
Therefore, it is desirable to adjust the first transmission interval and the second transmission interval to optimum values within a range that does not impair the practicality of grasping the vehicle position. Similarly, it is desirable that the first capacitance value be adjusted to an optimum value by the practitioner.
Further, the first capacitance value may not be a fixed value. For example, when a large amount of power is required, for example, when the distance to the base station is long and a large amount of transmission power is required, a variable threshold value such as increasing the first capacity value is set. Also good.

<When the starting state of the vehicle 1 is off>
When the activation information of the vehicle 1 is detected by the activation switch information detection unit 201, that is, the position information notification unit 208 detects that the engine of the vehicle 1 is stopped (system is stopped), the power from the battery unit 221 is detected. By the supply, the parking position information of the vehicle 1 is transmitted to the management server 3. In the following description, it is assumed that the position information notification unit 208 can transmit the parking position information of the vehicle 1 to the management server 3 based on the remaining capacity of the battery unit 221.

When the first determination unit 206 determines that the vehicle position information can be measured based on the GPS sensor 211, the position information notification unit 208 displays the vehicle position information measured by the GPS sensor 211 when the vehicle activation state is off. The management server 3 is notified together with the stop state information indicating that it exists.
At this time, the position information notification unit 208 notifies the management server 3 of the number of basement floors (for example, the first basement floor) or the number of ground floors (for example, the third floor above the ground) calculated by the altitude calculation unit 207. May be.
By doing so, the management server 3 can answer to the user the parking position of the vehicle 1 not only from the latitude and longitude but also from the altitude.

When the first determination unit 206 determines that the vehicle position information is not measurable based on the GPS sensor 211, the position information notification unit 208 succeeds in measuring the vehicle position information stored in the storage unit (latest (most recent). ) Is notified to the management server 3 together with stop state information indicating that the start state of the vehicle 1 is off and flag information indicating that the vehicle position cannot be measured.
At this time, the position information notification unit 208 notifies the management server 3 of the number of basement floors (for example, the first basement floor) or the number of ground floors (for example, the third floor above the ground) calculated by the altitude calculation unit 207. May be.
By doing so, the management server 3 can answer the user about the parking position of the vehicle 1 with reference to the altitude information.

Finally, a case where the position information notification unit 208 cannot transmit the parking position information of the vehicle 1 to the management server 3 due to insufficient capacity of the battery unit 221 will be described.
In this case, as described above, the vehicle 1 is parked after elapse of a time less than the second transmission interval from the position indicated by the vehicle position information most recently transmitted to the management server 3 (hereinafter referred to as “most recent position”). It is estimated to be.
For this reason, it becomes possible to estimate that the vehicle 1 is parked within the range of the distance that the vehicle 1 moves in the time of the second transmission interval from the nearest position.
For example, the user may turn off the ignition switch after completing the charging of the battery unit 221 so that the remaining capacity of the battery unit 221 exceeds a first value so that the remaining capacity exceeds the first capacity value. preferable.

[Management Server]
Next, the management server 3 will be described with reference to FIG. FIG. 3 shows a functional block diagram of the management server 3.

When the wireless server 2 detects that the vehicle 1 is parked, the management server 3 fails in positioning by GPS, and when the wireless server 2 can receive the parking position information of the vehicle 1 from the wireless terminal 2, the user terminal 4 Based on the request from, position information at the time when positioning by GPS was last successful is transmitted to the user terminal 4. At that time, the time calculated from the time when the positioning by the GPS was last successful and the time when the parking of the vehicle 1 was detected can be transmitted to the user terminal 4 together.

  For this reason, the management server 3 is communicably connected to the wireless terminal 2 and the user terminal 4, respectively, and includes at least a control unit 30, a storage unit 31, and a communication unit 32 as shown in FIG.

Details of the control unit 30 will be described later.

  The storage unit 31 includes, for example, a semiconductor memory, a hard disk drive, and the like, and stores various information such as an operating system (OS) and software called an application being saved.

  The user ID (subscriber ID) of the user terminal 4 is stored in the user ID area 3111 of the user information area 311 of the storage unit 31, and the vehicle ID of the vehicle 1 on which the user rides and the wireless terminal ID are stored in the user ID.

With reference to FIG. 6A, the process from step ST01 to step ST06 is demonstrated.
In step ST01, the ignition switch of the vehicle 1 is turned on and the system is activated. The activation switch information detection unit 201 detects that the activation state of the vehicle 1 is on.

  In step ST02, the remaining capacity detection unit 204 detects whether or not the remaining capacity of the battery unit 221 exceeds a preset first capacity value. When the remaining capacity exceeds the first capacity value (Yes), the process proceeds to step ST03. When the remaining capacity is equal to or less than the first capacity value (No), the process proceeds to step ST04.

In step ST03, the position information notification unit 208 transmits the vehicle position information to the management server 3 at a preset first transmission interval. Thereafter, the process proceeds to step ST05.
In step ST04, the position information notification unit 208 transmits the vehicle position information to the management server 3 at a second transmission interval that is shorter than the first transmission interval. Thereafter, the process proceeds to step ST05.

  In step ST05, the activation switch information detection unit 201 detects whether the activation state of the vehicle 1 is an off state (that is, whether the engine of the vehicle 1 is stopped). When the starting state of the vehicle 1 is on (Yes), the process proceeds to step ST02. When the starting state of the vehicle 1 is off (No), the process proceeds to step ST06.

  In step ST06, the power supply of the wireless terminal 2 is switched to the supply from the battery unit 221.

Next, processing from step ST07 to step ST11 will be described with reference to FIG. 6B.

When the wireless terminal 2 is larger than the capacity capable of wireless communication with the management server 3 (Yes), the process proceeds to step ST08. If the capacity of the wireless terminal 2 is less than the capacity capable of wireless communication with the management server 3 (No), the process proceeds to step ST11.

  In step ST08, the first determination unit 206 determines whether or not the vehicle position information can be measured based on the GPS sensor 211. When the vehicle position information can be measured based on the GPS sensor 211 (Yes), the process proceeds to step ST09. When vehicle position information cannot be measured based on the GPS sensor 211 (No), the process proceeds to step ST10.

  In step ST09, the position information notification unit 208 notifies the management server 3 of the vehicle position information measured by the GPS sensor 211 together with the stop state information indicating that the start state of the vehicle is an off state. Thereafter, the process proceeds to ST11.

In step ST <b> 10, the position information notification unit 208 indicates the latest (most recent) vehicle position information that has been successfully measured for the vehicle position information stored in the storage unit 23, indicating that the activation state of the vehicle 1 is off. The management server 3 is notified together with the stop state information and flag information indicating that the current position information of the vehicle 1 cannot be measured. Thereafter, the process proceeds to ST11.
