Based on this, the following will describe in more detail the vehicle terminal for remote control of an electric vehicle and its operating method.

<Example of operation method of vehicle terminal>

FIG. 1 is a flowchart illustrating an example of an operation method of a vehicle terminal according to an embodiment, and FIG. 2 is a block diagram showing an example of a remote system implementing the operation method of FIG. 1 according to an embodiment.

The remote system shown in FIG. 2 may include a vehicle terminal 100, a server 200, a mobile terminal 300, and a GPS 400.

First, the vehicle terminal 100 calculates the required battery capacity required for the electric vehicle to move from the current location of the electric vehicle to the charging station, and implements a mechanism to maximize the sleep mode by utilizing the calculated required battery capacity. .

The sleep mode may refer to an operating state in which messages can be received from the mobile terminal 300 while minimizing the operation of the vehicle terminal 100.

The reason for maximizing the sleep mode is that the mobile terminal 300 can remotely control the electric vehicle only through the vehicle terminal 100 in the sleep mode.

To this end, the vehicle terminal 100 may be connected to the mobile terminal 300 through short-distance communication, or may be connected to the mobile terminal 300 through a server 2000 connected to wireless communication.

This vehicle terminal 100 may be any one of a head unit, a telematics terminal, and a navigation terminal. However, it is not necessarily limited to this.

In one embodiment, when the vehicle terminal 100 wants to automatically send a necessary message to the mobile terminal 300, the server 200 sends the message indirectly through wireless communication if it is not connected to the mobile terminal 300 through short-distance communication. It exists to transmit and receive necessary messages to the mobile terminal 300.

The wireless communications mentioned include cellular communications (e.g., Global System for Mobile Communications (GSM), Enhanced Data Rates for GSM Evolution (EDGE), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), and Time Division. -Can be part of various types of wireless networks, including CDMA (TD-CDMA), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), or other cellular communications.

For example, if the network data access element(s) are part of a GSM network, the network data access element(s) may include a base transceiver station (BTS), a base station controller (BSC), a mobile switching center (MSC), and a serving station (SGSN). GPRS Support Node), etc. may be included.

On the other hand, the short-range communication mentioned may be wireless LAN, Wi-Fi, Bluetooth, zigbee, Wi-Fi Direct (WFD), or ultra wideband (UWB).

In one embodiment, the server 200 may be connected to the vehicle terminal 100 and the mobile terminal 300 through wireless communication, respectively. For this reason, the server 200 may also be referred to as a wireless network server.

In one embodiment, the above-described mobile terminal 300 may remotely control an electric vehicle by accessing the vehicle terminal 100 in a sleep mode based on required battery capacity. For example, remote control can be performed to move the electric vehicle from its current location to a charging station.

At this time, the actual implementation and processing of the operation method of FIG. 2 may be performed by the controller of the vehicle terminal 100. That is, the operation method of FIG. 1 can be implemented by the controller 110 of the vehicle terminal 100.

In addition, the vehicle terminal 100 includes a communication module 120 that transmits and receives data through the wireless communication or short-distance communication described above, a storage medium 130 that stores the transmitted and received data, and displays the transmitted and received data and data input by the user. It may further include various configurations such as an input/output interface 140 that processes .

However, it goes without saying that typical configurations not disclosed in this embodiment are also applied in this embodiment. In addition, the controller 110 of the vehicle terminal 100 described above can control the communication module 120, the storage medium 130, and the input/output interface 140 to perform the operation method of FIG. 1.

In one embodiment, the GPS 400 may obtain location information of a driving electric vehicle and transmit it to the vehicle terminal 100 through wireless communication. The location information of the electric vehicle can be used in the operation method of the vehicle terminal 100 of FIG. 1.

Hereinafter, the operation method of FIG. 1 implemented through the controller 110 of the vehicle terminal 100 described above will be described.

Referring to FIG. 1 , an operating method 400 by the controller 110 of the vehicle terminal 100 according to an embodiment may include steps 410 to 450.

First, in step 410 of one embodiment, the controller 110 may determine whether the battery of the electric vehicle is being charged through a charger.

For example, when the battery is being charged, the controller 110 may maintain a sleep mode at which messages sent from the mobile terminal for remote control can be received (411).

In step 420 of one embodiment, when it is determined in step 410 that the battery is not being charged, the controller 110 calculates the distance from the current location of the electric vehicle mapped on the map to the charging station and the required battery capacity in response. You can.

The distance may be one vector element needed to calculate the required battery capacity.

Here, in order to calculate the required battery capacity, the controller 110 may reflect the margin battery capacity according to temperature changes in the calculation of the required battery capacity. The reason for doing this is that electric vehicles have lower battery efficiency in high or low temperature environments and the driving range can be shortened due to heating and cooling, so there is a margin in the required battery capacity depending on the temperature change of the electric vehicle (e.g., below 0 degrees or above 30 degrees). Additional battery capacity (e.g. 10%) can be added.

In step 430 of one embodiment, the controller 110 may determine whether the required battery capacity calculated by step 420 described above is smaller than the measured remaining battery capacity. The remaining battery capacity can be measured through a sensor (not shown).

For example, the controller 110 may maintain the sleep mode when the calculated required battery capacity is less than the remaining battery capacity.

The reason for maintaining the vehicle terminal 100 in the sleep mode is that when the mobile terminal 300 performs remote control to move the electric vehicle to the charging station, the mobile terminal 300 is in the vehicle terminal ( This is to prepare for cases where you cannot access 100).

For example, the controller 110 may perform step 440 below when the calculated required battery capacity is greater than the remaining battery capacity.

In this way, this embodiment dynamically maintains the sleep mode of the vehicle terminal according to the charging amount of the electric vehicle to maximize the remote control time of the mobile terminal, and maximizes the sleep mode of the vehicle terminal based on the required battery capacity to a nearby charging station. It can be maintained.

In step 440 of one embodiment, the controller 110 may determine whether the battery is connected to the charger when the calculated required battery capacity is greater than the remaining battery capacity.

For example, when the battery is connected to the charger, the controller 110 may transmit a low-charge level and charging operation notification message to the mobile terminal 300 through the server 200 connected through short-distance communication or a wireless network (441).

However, when the controller 110 determines that the battery is not connected to the charger, it considers that the electric vehicle cannot sufficiently reach the charging station with only the current remaining battery capacity and terminates the sleep mode (442).

Finally, in step 450 of one embodiment, the controller 110 may determine whether to receive a charging execution request message from the mobile terminal 300 that has confirmed the charging execution notification message through short-distance communication or the wireless network server 200. .

For example, when the controller 110 receives a charging request message from the mobile terminal 300 through short-distance communication or a wireless network server, the controller 110 may charge the battery through the charger (451). This is to predict in advance that remote control of electricity movement to the charging station will not be possible and to charge the remaining battery capacity to make it larger than the required battery capacity.

However, when the controller 110 does not receive a charging request message from the mobile terminal 300, the controller 110 may end the sleep mode as described above (452).

As such, in this embodiment, the remote control time can be maximized by performing remote charging through a mobile terminal when the battery capacity is low, and even if remote charging is not performed, the customer is informed that remote control is not possible due to insufficient battery capacity. I can guide you.
