Conventional remote starters and alarms for vehicles have been commercialized in the form of various products ranging from a product having the functions of opening and closing the door of a vehicle and remotely starting a vehicle via unidirectional communication to a product capable of preventing a vehicle from being stolen and checking the state of a vehicle via bidirectional communication. Common remote starters and alarms may be classified into AM type devices using a frequency of 311 MHz and FM type devices using a frequency of 477 MHz according to their communication frequency, and may be classified into unidirectional type devices and bidirectional type devices according to their communication direction as described above. Among these devices, devices using smartphones enable users to remotely start their vehicles and to check the states of their vehicles using smartphones anytime and anywhere because the vehicles are equipped with the function of communicating with the smartphones. Remote vehicle-related services include remote vehicle start/stop, remote door closing and opening, and remote trunk closing and opening. Recently, a wireless control vehicle (Su Rui produced by BYD company of China) that can be remotely driven using a dedicated remote control over a distance within 10 m has been commercialized. Although this wireless remote control vehicle has a maximum hourly speed of 2 km/h when it is driven using a remote control, it provides convenience that eliminates the need to walk to the vehicle when a driver parks the vehicle or when it is raining. The remote control provides an intuitive interface based on door closing and opening function buttons and a touch pad, thereby enabling anybody to easily use remote control functions. However, since the above conventional remote starters and alarms can work within a distance close to a vehicle, they cannot be used to remotely control a vehicle parked in a parking lot from an office of a tall building or a apartment house and also it is difficult to check the state of a vehicle using them. The general-purpose vehicle remote control device according to at least one embodiment of the present invention can resolve the above problems.
The network communication unit 210 enables communication with the user who has accessed the general-purpose vehicle remote control device 200 over a network.
The user authentication unit 220 may identify a user by receiving information, such as an ID and a password, from the user attempting to access the general-purpose vehicle remote control device 200 and determining whether the input information matches information stored in the user information database 230. A user who first accesses the general-purpose vehicle remote control device 200 may input information, such as a new ID and a new password, to a user registration unit included in the user information database 230 and thus register with the user information database 230. Furthermore, when an existing user who has used the general-purpose vehicle remote control device 200 wants to change user information, he or she may change user information through an information update unit included in the user information database 230. In this case, the user information may be information, such as user personal information and vehicle information, including an ID and a password used to access the general-purpose vehicle remote control device 200.
The user information database 230 may store user information that is required when the user authentication unit 220 identifies the user. Furthermore, the user information database 230 includes the user registration unit and the information update unit, and may register information about a new user or change information about an existing user.
The remote control unit 240 may transceive control signals and state information with the vehicle of the user identified by the user authentication unit 220, and may remotely control the vehicle. In this case, the remote start interface included in the remote control unit 240 may transmit a remote start signal to the remote start device provided in the vehicle of the user. An existing remote start device having been used in the vehicle may be used without change as the remote start device provided in the vehicle. Since the types of remote start devices provided in vehicles may be various, all vehicles may be remotely started by providing at least one type of remote start interface in the remote control unit 240.
Furthermore, the remote control unit 240 enables the general-purpose vehicle remote control device 200 and the vehicle to transceive control signals and state information. In this case, the control signals may include control signals operative to perform the opening/closing of the door, operation of the air conditioner and heater and opening/closing of the trunk of the vehicle. Furthermore, the state information may be information about the internal temperature state, door closed state, trunk closed state, external impact state, battery charged state, and fuel state of the vehicle. In this case, the state information received from the vehicle general-purpose vehicle remote control device 200 may be output to the accessing user so that the user can view it. Furthermore, when the vehicle supports a private communication network for a service, such as remote control or autonomous driving, the units for the private communication network may be powered up by transmitting a start signal to the vehicle. When a conventional vehicle remote control device uses a private communication network, it is problematic in that communication cost is excessive or the battery of a vehicle is discharged because power is always supplied to the private communication network. In contrast, in the present invention, in order to resolve the above problem, the units for the private communication network is powered up and then used after the starting of a vehicle via the remote control unit 240. In this case, the private communication network is a bidirectional communication-enabled network, and may be a 3G network or a wireless local area network (LAN). Meanwhile, the remote control unit 240 may transceive control signals and state information each having a size equal to or smaller than a preset data size with a vehicle in the state in which the vehicle has not been started. When state information requiring high power consumption, such as a video, is transmitted, a vehicle is started via the remote control unit 240 and then communication is performed through the units for the private communication network deployed in the vehicle.
FIG. 3 is a flowchart of a general-purpose vehicle remote control method according to an embodiment of the present invention.
Referring to FIG. 3, in the general-purpose vehicle remote control method according to this embodiment of the present invention, the general-purpose vehicle remote control device may be accessed over a network at step S310. The general-purpose vehicle remote control device may be accessed using a remote control terminal, such as a smartphone or a PC in any place where a network is connected.
Thereafter, to identify the user who attempts to access the general-purpose vehicle remote control device, the step of identifying the user using the user authentication unit is performed at step S320. The identification of the user may be performed using an ID and a password received from the user attempting to access the general-purpose vehicle remote control device and the user information stored in the user information database. If the user who attempts to access the general-purpose vehicle remote control device is a new user whose information is not present in the user information database, the user information of the user may be registered and then used via the user registration unit. In this case, the user information may be information, such as the user personal information and vehicle information, including an ID and a password. Furthermore, when a user whose information is present in the user information database wants to change existing information, the information may be changed using the information update unit.
Whether to remotely start a parked vehicle is determined based on a service desired by the identified user at step S325.
If, as a result of the determination at step S325, it is determined that it is necessary to remotely start the vehicle, the vehicle may be started by transmitting a start signal to the vehicle at step S330. The remote control unit may include a remote start interface capable of transmitting a start signal to the parked vehicle. In this case, the remote start interface may remotely start the vehicle by transmitting a start signal to a remote start device installed in the vehicle. Since the types of remote start devices provided in vehicles may be various, all vehicles may be remotely started by providing remote start interface, the remote start interface may be at least one type or more in the remote control unit.
Thereafter, control signals and state information may be transceived with the vehicle, or the units for the private communication network provided in the vehicle may be powered up and a remote control or autonomous driving service may be provided to the vehicle at step S340. After the vehicle has been started, control signals and state information may be transceived with the vehicle through the remote control unit via bidirectional communication. After the vehicle has been started, the general-purpose vehicle remote control device may remotely control the vehicle by transmitting a control signal desired by the user to the vehicle, and may receive the current state information of the vehicle from the vehicle reception and display it to the user. The control signals operative to remotely control the vehicle may include signals operative to perform the opening/closing of the door, operation of the air conditioner and heater and opening/closing of the trunk of the parked vehicle. Furthermore, the state information may be information about the internal temperature state, door closed state, trunk closed state, external impact state, battery charged state and fuel state of the vehicle. In this case, if units for a private communication network has been installed in the vehicle, the units for the private communication network is not powered up when the vehicle has not been started and is powered up when the vehicle has been started. The reason why the units for the private communication network is powered up by using the above-described method is that a communication cost problem and a vehicle battery discharge problem that occur when the units for the communication network is always powered up can be prevented by using the method. In this case, the private communication network used is a bidirectional communication-enabled network, and may be a 3 G communication network or a wireless LAN.
If, as a result of the determination at step S325, it is determined that remote start is not necessary, data having a limited data size as the control signals and the state information may be transceived with the vehicle not started through the remote control unit at step S350.
