Description

Technical Field

[0001] Exemplary embodiments of this disclosure relate to a vehicle lock control device and a control method thereof, the method of switching an anchor to a sleep mode to reduce power consumption, and resetting the anchor to disengage from the sleep mode in order to send and receive signals for unlocking the vehicle, receiving the signals and unlocking the vehicle. Background Technology

[0002] A smart key has been introduced into the vehicle and configured to unlock the doors based on the driver's proximity.

[0003] In a smart key system, when a driver holding a smart key approaches his / her vehicle and then approaches the anti-theft unit installed on the vehicle, the anti-theft unit performs a process of authenticating whether the driver's smart key is a valid key, and when the smart key is a valid key, the anti-theft unit operates as a smart key function.

[0004] When the smart key function is used in a vehicle with a smart key system, the driver with a valid smart key can enter the vehicle and unlock the doors or trunk without manual operation, and can start the engine for driving with a simple touch, without having to start the engine manually.

[0005] However, while the smart key system can improve user convenience, it lacks a way to distinguish between the person holding the smart key and approaching the vehicle and the legitimate user (driver). Furthermore, it has the problem that even when the driver with the smart key unlocks the door, it cannot prevent outsiders from opening the door.

[0006] Therefore, although the method of pressing the button of the smart key multiple times or registering and identifying the driver's portable terminal exists, there is a problem of high power consumption when waiting to receive signals from the portable terminal, which can lead to accidents such as battery discharge.

[0007] Therefore, there is a need for a method that can easily detect driver approach, prevent unnecessary external access, and reduce power consumption.

Therefore, these terms should be defined based on the content of the entire specification.

[0035] Figure 1 This is a block diagram schematically illustrating the configuration of a vehicle lock control device according to an embodiment of the present disclosure.

[0036] like Figure 1 As shown, vehicle 10 includes multiple anchors 160, communication module 170, detector 120, door driver 130, data storage 140, display 150, and processor 110 for controlling overall operation.

[0037] Vehicle 10 can be an electric vehicle or a hybrid electric vehicle that is driven by an electric motor powered by the discharge power of a battery, and can be equally applied to internal combustion engine vehicles operated by an engine.

[0038] Multiple anchors 160 are devices used to communicate with terminal 90 and receive signals sent from terminal 90.

[0039] Multiple anchors 160 receive signals from a terminal 90 acting as an initiator (UWB initiator). Preferably, the terminal 90 is pre-registered.

[0040] In this configuration, terminal 90 is a device configured as an initiator and pre-registered, and can be either a fixed object (FOB) or a mobile communication terminal. Furthermore, terminal 90 may include a smart key.

[0041] Multiple anchors 160 and terminals 90 communicate wirelessly with each other using the UWB method.

[0042] UWB is a wireless communication method that uses signals with a bandwidth of 500MHz or more in the frequency band of 6Hz to 8GHz. It is a technology that calculates the distance between communication objects by multiplying the arrival time of signals between communication objects by the speed of light using Time-of-Flight (ToF) technology.

[0043] Multiple anchors 160 include anchors one through seven.

[0044] Multiple anchors 160 are installed at multiple locations on the vehicle 10 to receive signals from the terminal 90 and transmit the received signals to the processor 110 via the communication module 170.

[0045] The communication module 170 uses Controller Area Network (CAN) communication to send or receive data in the vehicle.

[0046] The communication module 170 may include a module for wireless communication other than CAN communication to receive traffic information from external sources, etc.

[0047] The detector 120 includes multiple sensors installed in the vehicle. The detector 120 includes a temperature sensor, a door sensor, a seat sensor, a distance sensor, etc. Additionally, the detector 120 includes a button mounted on the door handle.

[0048] In addition, detector 120 includes a proximity sensor (not shown) for detecting objects approaching the vehicle within a certain distance, and a touch sensor mounted on the door handle for detecting touch.

[0049] Proximity sensors are installed on each of the multiple doors to detect objects approaching within a certain distance, while touch sensors receive detection signals by detecting when a door handle is gripped and input these signals to a processor. When a button on the door handle is operated, a detection signal can be input to the processor in the same way as a touch sensor.

[0050] The door actuator 130 locks and unlocks the door based on switch or button operation.

[0051] Furthermore, the door actuator 130 locks or unlocks the door in response to detection signals from the detector 120 and control commands from the processor 110. The door actuator 130 can also control the opening or closing of windows installed on the door.

[0052] The data storage device 140 stores control data for controlling vehicle operation, reference data for determining operating status, and driving data for controlling driving. The data storage device 140 also stores sensor data detected by the detector 120 and data transmitted or received via the communication module 170.

[0053] Display 150 includes at least one display and multiple lights, and displays the vehicle's operating status, whether any abnormalities exist, etc. Display 150 may include a front navigation display, a head-up display (HUD), etc.

[0054] The processor 110 controls the vehicle's movement based on the driving algorithm of the automatic driving system and the steering device (not shown) and braking system (not shown) operated by the driver. The processor 110 controls the braking system so that the braking is automatically applied when the vehicle stops or comes to a complete stop.

[0055] In response to signals received from multiple anchors 160, the processor 110 locks or unlocks the vehicle after determining the location of the terminal. The processor 110 can unlock any one door or can control multiple doors simultaneously.

[0056] Furthermore, the processor 110 can control engine start based on signals received from multiple anchors 160. When the terminal is inside the vehicle, the processor 110 controls engine start.

[0057] The processor 110 can unlock the vehicle in response to signals received from multiple anchors 160 and detection signals from the detector 120.

[0058] In addition, the processor 110 can analyze signals received from multiple anchors 160, calculate the position of the terminal 90, and track changes in position.

[0059] When processor 110 receives signals from at least three anchors, it calculates the distance between the position of terminal 90 and the position of the vehicle using the corresponding signals based on a triangulation method. Processor 110 may use one or two signals to calculate the position of the terminal. However, since three or more signals can be used to calculate a more accurate position, the processor preferably uses three or more signals to calculate the position of the terminal.

[0060] Based on the number of anchors receiving signals among multiple anchors 160 within a first set time period, the processor 110 can stop the waiting state of some anchors by switching the mode of some anchors to sleep mode.

[0061] In addition, the processor 110 can switch the anchor's mode to standby mode by resetting the anchor that has entered hibernation mode to exit hibernation mode.

[0062] Therefore, vehicle 10 can identify the position of terminal 90 through multiple anchors 160 and compare the position of terminal 90 with the position of door according to the detection signal of detector 120 to unlock the door at a specified position.

[0063] Furthermore, based on the detection signal, when the position of terminal 90 differs from the position of the door, vehicle 10 remains locked. Simultaneously, when the terminal is inside the vehicle, vehicle 10 controls the engine to start based on the anchor signal.

[0064] Figure 2A and 2B It is used to describe in Figure 1 A reference diagram showing the operation of receiving terminal signals via an anchor in a lock control device.

[0065] like Figure 2A As shown, multiple anchors 160 (161 to 167) are installed in vehicle 10.

[0066] Multiple anchors 160 receive signals sent from terminal 90 via UWB communication in order to transmit the received signals to processor 110. Each of the multiple anchors 161 to 167 is connected to the CAN communication line N of communication module 170 to send signals to processor 110.

[0067] Multiple anchors 160 operate in standby mode while receiving signals from terminal 90, and the number of anchors receiving signals varies depending on the position of terminal 90 and the position of the anchors.

[0068] When terminal 90 is located near the driver's seat on the left side of vehicle 10, the first anchor 161, the fourth anchor 164, the fifth anchor 165 and the seventh anchor 167 receive signals from terminal 90.

[0069] Meanwhile, because vehicle 10 or objects inside the vehicle act as obstacles, the second anchor 162, the third anchor 163, and the sixth anchor 166 do not receive signals.

[0070] In addition, such as Figure 2B As shown, when terminal 90 is located near the passenger seat on the right side of vehicle 10, the second anchor 162, the third anchor 163, the fifth anchor 165 and the sixth anchor 166 can receive signals.

[0071] When processor 110 receives a signal from at least one anchor, processor 110 calculates the position of terminal 90 in response to the received signal.

[0072] In addition, the processor 110 detects anchors that have received signals and controls them to enter a sleep mode in response to the number of anchors receiving signals, the waiting time, etc., or switches the mode of anchors in a signal waiting state to a waiting mode by resetting anchors in a sleep mode.

[0073] like Figure 2A As shown, the first anchor 161, the fourth anchor 164, the fifth anchor 165 and the seventh anchor 167 receive the signal from the terminal 90 at the first time and send the signal to the processor 110.

[0074] Meanwhile, the second anchor 162, the third anchor 163, and the sixth anchor 166 did not receive a signal from the terminal 90 and remained in a waiting mode for receiving terminal signals.

[0075] The second anchor 162, the third anchor 163, and the sixth anchor 166 wait until they receive a terminal signal. When anchor 160 waits for a long time, that is, when the waiting time has passed the first set time or longer, power consumption increases.

[0076] If the state of not receiving a signal from the anchor remains for a first set time or longer, the processor 110 switches the mode of the corresponding anchor to sleep mode.

[0077] Sleep mode is a power-saving mode in which the anchor waits for the receiving terminal signal while in a ranging state.

[0078] Meanwhile, with the second anchor 162, the third anchor 163, and the sixth anchor 166 already in sleep mode, when terminal 90 is located in the same position as... Figure 2B When in the same position, even in a receptive position, the second anchor 162, the third anchor 163, and the sixth anchor 166 may be unable to receive signals because they are in a dormant state.

[0079] Therefore, when the number of anchors receiving signals is less than the set number and the state is maintained for a second set time (m), the processor 110 resets multiple anchors 160 to enter a waiting mode.

[0080] When the fifth anchor 165 receives a signal and sends the signal to the processor 110, the processor 110 may not be able to identify the exact location of the terminal, but it can identify the direction of the terminal and reset multiple anchors by determining that the terminal is located at a certain distance from the vehicle.

[0081] Processor 110 resets multiple anchors, so second anchor 162, third anchor 163 and sixth anchor 166 enter standby mode to receive signals from terminal 90.

[0082] The processor 110 calculates the position of the terminal 90 based on signals received from the second anchor 162, the third anchor 163, the fifth anchor 165, and the sixth anchor 166, and sends control commands to the gate driver 130 in response to detection signals received from the detector 120.

[0083] Therefore, the door actuator 130 can control the door of the passenger seat to be unlocked.

[0084] Meanwhile, when the terminal 90 is determined to be near the passenger seat based on the signals received from the second anchor 162, the third anchor 163, the fifth anchor 165 and the sixth anchor 166, when the detection signal of the handle touch is input from the door of the driver's rear seat, the processor 110 keeps the door locked because the position of the terminal and the position of the door being tried to open are different.

[0085] When the mode is set to open, the processor 110 can unlock multiple doors in response to detection signals and terminal signals.

[0086] In addition, the processor 110 determines the position of the terminal 90 based on signals received from multiple anchors 160, and controls the vehicle's engine to start when the terminal is inside the vehicle.

[0087] Figures 3A to 3C It is used to describe in Figure 1 A reference diagram showing the range of the receiving terminal signal in the lock control device.

[0088] like Figure 3A As shown, multiple anchors 160 remain in a waiting state to receive signals from terminal 90.

[0089] Terminal signals are generated at a certain period and received once in each block, and signals are sent at certain time intervals according to each block.

[0090] Therefore, the anchor waits to receive signals sent from terminal 90 to the first block 11 and the second block to the eighth block.

[0091] When the first block 11 is within the range from time 0 to time t1, each of the second to eighth blocks can remain in a waiting state at the second time t2 to the seventh time t7, which have the same time interval.

[0092] A block can consist of approximately 192ms, and a round can be divided into 1 to 24ms, but this can be changed depending on the settings.

[0093] like Figure 3B As shown, a block, for example, the first block 11 consists of the first round 21 to the eighth round 28.

[0094] Signals from terminal 90 can be received during the first round.

[0095] In this scenario, a second current I02 is applied to the anchor simultaneously with receiving the signal, while the anchor maintains a first current I01 after receiving the signal. For example, the first current I01 is approximately 25 mA, and the second current I02 is approximately 100 mA.

[0096] Since a signal is received in the first block 11, the corresponding anchor has a first current I01 after receiving a signal in the first wheel 21.

[0097] At the same time, such as Figure 3C As shown, when no signal is received in the first round 21, the anchor remains in a waiting state in the order of the second round 22 and the third round 23. In this case, the current of the anchor in the waiting state becomes the second current I02.

[0098] Therefore, when the waiting state continues for a first set time or longer, the power consumption of the anchor increases, and when multiple anchors remain in the waiting state, the power consumption may increase proportionally to the number of anchors.

[0099] After waiting for a first set time, the processor 110 controls the anchor that has not received a signal to enter sleep mode.

[0100] Furthermore, when the number of anchors receiving signals is a specific number or less and remains so for a second set time, the processor 110 resets multiple anchors to enter a waiting mode, depending on the number of anchors receiving signals.

[0101] For example, since at least three signals are required to track the position of terminal 90, processor 110 can reset multiple anchors if the state of receiving less than 3 anchors remains for a second set time or longer.

[0102] Even if signals are received from fewer than three anchors, the processor 110 can use one or two signals to calculate the terminal's position. However, since a more accurate position can be calculated when three or more signals are used, the anchor reset can be determined based on three signals.

[0103] When the number of anchors receiving signals remains at zero for a first set time or longer, all anchors enter sleep mode.

[0104] In this scenario, when all anchors enter sleep mode, the processor can periodically reset multiple anchors into wait mode at specified intervals because multiple anchors may not receive the terminal signal even if the terminal sends it.

[0105] Figure 4 This is a flowchart illustrating a control method for a vehicle lock control device according to an embodiment of the present disclosure.

[0106] like Figure 4 As shown, multiple anchors 160 (161 to 167) installed in vehicle 10 wait in a waiting mode to receive signals sent from the corresponding terminal (e.g., a pre-registered terminal 90) (S310).

[0107] When one of the multiple anchors receives a signal from the terminal 90 or the smart key (S320), the anchor that received the signal sends data about the signal reception to the processor 110 via CAN communication through the communication module 170.

[0108] When no signal is received from the anchor for a first set time (n) or longer, that is, when the anchor does not receive a signal from the terminal 90 for a first set time or longer, the processor 110 switches the mode of the multiple anchors to sleep mode (S340).

[0109] For example, when the first anchor 161 and the fourth anchor 164 receive signals at the first time and send the received signals to the processor 110, when the processor 110 receives a signal from the first anchor 161 at the second time, the processor 110 controls the first anchor 161 to remain in a waiting mode, and when no signal is received from the fourth anchor 164 after the nth time since the first time, the processor 110 controls the fourth anchor 164 to enter a sleep mode.

[0110] Therefore, the first anchor 161 remains in a waiting state, while the fourth anchor 164 enters a sleep mode and no longer receives signals. When no signal is received from the first anchor 161 after the second time period, the processor 110 also switches the mode of the first anchor 161 to sleep mode.

[0111] Meanwhile, when a signal is received from at least one anchor, the processor 110 counts the number of anchors that received the signal and determines whether the number of anchors that received the signal is greater than or equal to a set number (S350).

[0112] In other words, the processor 110 receives signals from the terminal 90 and calculates the number of anchors sending signals to the processor 110. The processor 110 may also use one or two signals to calculate the position of the terminal, but preferably uses at least three signals to calculate the position for a more accurate result.

[0113] Therefore, since at least three signals can be used to calculate the accurate position, three or more can be used as the set quantity. In some cases, the set quantity can be changed.

[0114] When the number of anchors receiving signals is less than a set number, the processor 110 counts the time the state of the number of anchors receiving signals being less than the set number is maintained, and when the count time is a second set time (m) or longer (S360), the processor 110 resets multiple anchors 161 to 167 to release the sleep mode and switches the mode of multiple anchors 161 to 167 to the waiting mode (S370).

[0115] When the number of anchors is less than the set number, the processor 110 calculates the position of the terminal based on the received signals.

[0116] When the number of anchors receiving signals is greater than or equal to a set number, the processor 110 uses the multiple signals received from the anchors to calculate the position of the terminal 90 (S380).

[0117] In addition, the processor 110 determines whether a detection signal has been input from the detector 120 (S390).

[0118] The processor 110 can receive detection signals from a touch sensor mounted on the door. Furthermore, when a button mounted on the door handle is operated, the processor 110 can receive detection signals based on the button operation.

[0119] When no door handle signal (i.e., a signal from a sensor or button) is received, the processor 110 repeatedly calculates the position of the terminal 90 via the anchor and tracks the position of the terminal 90 (S310 to S390).

[0120] When a signal is received from a sensor or button operation based on the door handle, the processor 110 compares the position of the door receiving the signal with the position of the calculated terminal 90 to determine whether their positions are the same (S400).

[0121] Meanwhile, when the position of the door receiving the signal is different from the position of the terminal 90, the processor 110 outputs a warning (S410) and remains locked.

[0122] When the position of the door at the received signal is the same as the position of the terminal 90, the processor 110 unlocks the door of the vehicle 10 (S420).

[0123] When the position of a door is the same as the position of a terminal, the processor 110 can unlock only the door that is in the same position as the terminal, according to the settings. Furthermore, when the position of a door is the same as the position of a terminal, the processor 110 can unlock all doors among multiple doors.

[0124] Furthermore, when the terminal is in a state where it receives signals from multiple doors and the position of the terminal is the same as the position where the signals from multiple doors are received, the processor 110 can unlock only the door located at the position where the door signal is received.
