[0002] This application claims priority and benefit to Korean Patent Application No. 10-2020-0141555, filed on October 28, 2020, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to an apparatus and method for recording video in a vehicle. Background Technology

[0004] The statements in this section are provided only as background information in relation to this disclosure and may not constitute prior art.

[0005] Continuously recording video around a vehicle even when it is stationary can increase its power consumption and cause it to discharge. Therefore, a method is proposed that uses radar to sense the motion of objects around the vehicle. For example, video recording is performed when the camera senses motion of objects around the vehicle, thereby reducing or minimizing the current consumption used in vehicle recording.

[0006] However, we have found that because radar interacts with objects containing dielectric materials, the motion of those objects can be continuously determined and sensed during rain or snow. Therefore, unnecessary power may be wasted by operating a camera to record video during rain or snow. Summary of the Invention

[0007] This disclosure solves the aforementioned problems in the prior art while retaining the advantages achieved by the prior art.

[0008] One aspect of this disclosure provides an apparatus and method for recording video in a vehicle, which reduces power consumption by controlling the video recording mode in rainy or snowy conditions when the vehicle is parked and video recording is performed using radar.

[0009] The technical problems to be solved by this disclosure are not limited to those described above, and any other technical problems not mentioned herein will be clearly understood by those skilled in the art to which this disclosure pertains through the following description.

[0010] According to one aspect of this disclosure, an apparatus for recording video in a vehicle may include: a camera for acquiring video of the area around the vehicle; a first sensor for sensing motion around the vehicle; a second sensor for sensing impacts from the area around the vehicle; and a controller for determining a video recording mode of the camera based on whether the motion around the vehicle is continuous for a specific time period or more, and controlling the operation of the camera and the first sensor according to the determined video recording mode.

[0011] When motion around the vehicle is sensed for more than a first time period, the controller can determine the video recording mode as a periodic recording mode, and control the camera and the first sensor to repeatedly operate and pause.

[0012] The apparatus further includes a third sensor for sensing water droplets on a surface of the vehicle.

[0013] In one form, when motion around the vehicle is sensed for more than a second time period, and when the third sensor senses water droplets on the surface of the vehicle, the controller can determine the video recording mode as the periodic recording mode, and control the camera and the first sensor to repeatedly operate and pause.

[0014] The controller can vary the operation time of the camera and the first sensor according to an amount of water droplets sensed by the third sensor.

[0015] The controller can decrease the operation time of the camera and the first sensor as the amount of water droplets sensed by the third sensor increases, and control the camera and the first sensor to operate for the decreased operation time.

[0016] The controller can control the second sensor to sense an impact from around the vehicle in a state in which the camera and the first sensor are paused.

[0017] In the state in which the camera and the first sensor are paused, when the second sensor senses an impact from around the vehicle, the controller can wake up the camera and control the camera to record a video for a third time period after the impact is sensed.

[0018] The controller can determine an operation mode of a wiper according to the video recording mode after the impact is sensed.

[0019] In another form, when motion around the vehicle is sensed for less than a certain time period, the controller can determine the video recording mode as a low-power parking recording mode, start operation of the camera after the motion is sensed, and perform the operation of the camera for the certain time period after the motion ends.

[0020] According to another aspect of the disclosure, a method for recording a video in a vehicle can include determining, by a controller, a video recording mode of a camera according to whether motion around the vehicle is continuous for more than a certain time period, and controlling operation of the camera and a first sensor according to the determined video recording mode.

[0021] When motion around the vehicle is sensed for more than a first time period, the video recording mode can be determined as a periodic recording mode, and the camera and the first sensor can be controlled to repeatedly operate and pause.

[0022] When motion around the vehicle is sensed for more than a second period of time, and when a water droplet on the surface of the vehicle is sensed, the video recording mode can be determined as a periodic recording mode, and the camera and the first sensor can be controlled to repeat operation and pause.

[0023] The operation time of the camera and the sensor can be reduced as the amount of water droplets on the surface of the vehicle increases, and the camera and the first sensor can be controlled to operate for the reduced operation time.

[0024] In the state in which the camera and the first sensor are paused, an impact from around the vehicle can be sensed by the second sensor.

[0025] In the state in which the camera and the first sensor are paused, when an impact from around the vehicle is sensed by the second sensor, upon sensing the impact, the camera is woken up and controlled to perform video recording for a third time.

[0026] The method can further include determining an operation mode of the wiper according to the video recording mode upon sensing the impact.

[0027] The video recording mode can be determined as a low-power parking recording mode, the operation of the camera is started upon sensing the motion, and when motion around the vehicle is sensed for less than a certain time, the operation of the camera can be performed for a certain time after the motion ends.

[0040] Figure 1 is a diagram illustrating a configuration of an apparatus for recording a video in a vehicle according to one exemplary form of the disclosure.

[0041] As Figure 1 shown, in one form of the disclosure, an apparatus 100 for recording a video in a vehicle can include a sensor 110, a camera 120, a power supply 130, and a controller 140.

[0042] The sensor 110 can sense a motion around the vehicle or an impact around the vehicle. According to one form of the present disclosure, the sensor 110 can sense a speed of an object having a dielectric constant to sense a motion around the vehicle, and can be implemented with a radar. The radar can be provided in a built-in camera mounted in an interior of the vehicle, and can include a radar for an advanced driver assistance system (ADAS). According to another form of the present disclosure, when the radar for the ADAS is used, only an array (e.g., 2x2) smaller than an array (e.g., 4x4) of the radar can be used. Accordingly, only a region within a certain distance is sensed to reduce power consumption. In addition, the sensor 110 can be implemented with an impact detection sensor (G sensor) for sensing an impact around the vehicle.

[0043] In addition, the sensor 110 can include a rain sensor that senses a water droplet on a surface of the vehicle. The rain sensor can sense the water droplet on the surface of the vehicle through infrared reflection. For example, when the infrared ray is regularly reflected, the rain sensor can determine that the water droplet is not sensed, and when the infrared ray is diffusely reflected, it can be determined that the water droplet is sensed. In addition, the rain sensor can classify the amount of water droplets based on stages according to the degree of diffuse reflection, and can sense a change in the water droplet. According to another form of the present disclosure, the rain sensor can classify the sensed amount of water droplets into five stages. For example, as the amount of water droplets increases or the change in the water droplets increases, the rain sensor can increase the stages.

[0044] The camera 120 can obtain a video around the vehicle. According to another form of the present disclosure, the video around the vehicle can include a video in driving, a video in parking, a video at the time of an event, a video taken at the front and rear of the vehicle, and a video taken at the left and right sides of the vehicle. To this end, the camera 120 can be provided at the front and rear of the vehicle, and can be provided at the left and right sides of the vehicle.

[0045] The power supply 130 can provide power required when the controller 140 performs a control operation, and can include an auxiliary battery.

[0046] According to another form of the present disclosure, the controller 140 can be implemented with various processing devices, such as a microprocessor having a semiconductor chip embedded therein, to operate or execute various instructions, and can control the overall operation of the device for recording a video in the vehicle. In detail, the controller 140 can determine a video recording mode of the camera according to whether a motion around the vehicle is continuous for a certain time, and can control the operation of the camera and the sensor (radar) according to the determined video recording mode.

[0047] When the vehicle is in a parked state, the controller 140 can enter a low-power parking recording mode that records a parking lot in a low power consumption. In this case, in the low-power parking recording mode, the controller 140 can control the camera to be in a pause state, and can control only the sensor (radar) to be kept in an operating state, thereby sensing a motion around the vehicle.

[0048] The controller 140 can sense a motion around the vehicle in a state in which only the radar is in an operating state. In this case, when the rain sensor is provided, the controller 140 can sense a motion around the vehicle by simultaneously using the radar and the rain sensor. In addition, when the rain sensor is not provided, the controller 140 can sense a motion around the vehicle by using only the radar. Hereinafter, the operation of the controller 140 will be described in the case of distinguishing between the provision and non-provision of the rain sensor.

[0049] First, hereinafter, the operation of the controller 140 will be described in the case of non-provision of the rain sensor.

[0050] The controller 140 can enter the low-power parking recording mode to perform an operation of generally recording a parking video (general parking video recording operation). In this case, in the general parking video recording operation, the controller 140 can perform a control operation to start the operation of the camera upon sensing a motion, and to perform the operation of the camera for a certain time (for example, 10 seconds) after the motion ends.

[0051] In addition, the controller 140 can determine whether a motion around the vehicle is sensed for more than a first time. When a motion around the vehicle is sensed for less than the first time (for example, 10 minutes), the controller 140 can determine (keep) a video recording mode of the camera as the low-power parking recording mode.

[0052] When it is determined that a motion around the vehicle is sensed for more than the first time (for example, 10 minutes), the controller 140 can determine a state in which it rains or snows outside the vehicle. When it is determined that a motion around the vehicle is sensed for more than the first time (for example, 10 minutes), the controller 140 can determine a video recording mode of the camera as a periodic recording mode that periodically records a video, and can control the camera and the sensor to repeatedly operate and pause. According to another form of the present disclosure, the controller 140 can control the camera and the sensor (radar) to repeatedly operate for a time 'A' (for example, 10 seconds), and then pause for the time 'A'.

[0053] When the operations of the camera and the radar are performed for a time 'A', the controller 140 can determine whether motion around the vehicle is sensed. When the operations of the camera and the radar are performed for a time 'A', the controller 140 can determine whether the number of motions sensed around the vehicle is '0'. When the operation of the radar is performed for a time 'A', and when the controller 140 can not determine that the number of motions sensed around the vehicle is '0', the controller 140 can determine the surrounding situation as a situation in which it is raining or snowing outside the vehicle. The controller 140 can control the video recording mode of the camera to be the periodic recording mode. Meanwhile, when the operations of the camera and the radar are performed for a time 'A', and when the controller 140 determines that the number of motions sensed around the vehicle is '0', the controller 140 can control the camera to enter the low-power parking recording mode and perform the general parking video recording operation.

[0054] When the camera and the sensor are in the suspended state for a time 'A', the controller 140 can control the impact detection sensor to sense an impact from around the vehicle. When the camera and the sensor (radar) are in the suspended state for a time 'A', and when the impact detection sensor senses an impact from around the vehicle, the controller 140 can wake up the camera and control the camera to perform a video recording operation for a predetermined time (for example, 20 seconds) after the impact is sensed. When the camera and the sensor (radar) are in the suspended state for a time 'A', and when no impact from around the vehicle is sensed, the controller 140 can control the camera and the sensor to perform the periodic recording mode.

[0055] When the ignition is turned on or the remaining level of the battery is less than a threshold value, the controller 140 releases the low-power parking recording mode. Otherwise, the controller 140 can perform a control operation to re-enter the low-power parking recording mode.

[0056] Hereinafter, the operation of the controller 140 will be described with respect to a case in which a rain sensor is provided, according to one exemplary form of the present disclosure.

[0057] When the vehicle is parked or stopped, the controller 140 can enter the low-power parking recording mode to perform the general parking video recording operation. In addition, the controller 140 can determine whether motion around the vehicle is sensed for a second time (for example, 5 minutes). When motion around the vehicle is sensed for less than the second time, the controller 140 can determine (keep) the video recording mode of the camera to be the low-power parking recording mode. According to another form of the present disclosure, when the general parking video recording operation is performed, the controller 140 can perform a control operation to start the video recording operation of the camera after motion is sensed, and perform the video recording operation of the camera for 10 seconds after the motion ends.

[0058] When it is determined that motion around the vehicle is sensed for a second time (e.g., 5 minutes), the controller 140 can determine the object around the vehicle as continuously moving, or can determine the surrounding situation as a situation in which it is raining. The controller 140 can determine whether a rain sensor senses water droplets on the surface of the vehicle. When the rain sensor senses water droplets on the surface of the vehicle, the controller 140 can determine whether the motion around the vehicle is due to rain or snow. Meanwhile, when the rain sensor does not determine that water droplets on the surface of the vehicle are sensed, the controller 140 can perform a control operation to enter a low-power parking recording mode to perform a general parking video recording operation.

[0059] Meanwhile, when it is determined that the rain sensor senses water droplets on the surface of the vehicle, the controller 140 can determine a video recording mode of the camera as a periodic recording mode, and can perform a control operation to repeat operation and pause the camera and the sensor (radar). According to one exemplary form of the present disclosure, the controller 140 can set the periodic recording mode according to an amount of water droplets or a change in water droplets on the surface of the vehicle sensed by the rain sensor. The controller 140 can classify the mode into a first mode, a second mode, and a third mode according to the amount of water droplets or the change in water droplets on the surface of the vehicle sensed by the rain sensor, and can set an operation time and a pause time of the camera and the radar for each mode. For example, as the amount of water droplets or the change in water droplets on the surface of the vehicle sensed by the rain sensor increases, the controller 140 can decrease the operation time of the camera and the radar, and can control the camera and the radar to operate for the decreased operation time. Details thereof will be described with reference to FIGS. 6 to 8. Figure 2

[0060] Figure 2 is a view schematically showing a control operation in a periodic recording mode according to another form of the present disclosure.

[0061] As shown in Figure 2 When the amount of water sensed by the rain sensor is in a third stage (water droplet amount or change in water droplets: medium), the controller 140 can perform a control operation to repeat operation of the camera and the radar for a time 'A' (e.g., 10 seconds) and pause the camera and the radar for the time 'A'. In addition, when the amount of water sensed by the rain sensor is in a fourth stage (water droplet amount or change in water droplets is more increased than in the third stage), the controller 140 can perform a control operation to repeat operation of the camera and the radar for a time 'B' (e.g., 5 seconds) and pause the camera and the radar for the time 'A'. Also, when the amount of water sensed by the rain sensor is in a fifth stage (water droplet amount or change in water droplets is more increased than in the fourth stage), the controller 140 can perform a control operation to repeat operation of the camera and the radar for a time 'C' (e.g., 3 seconds) and pause the camera and the radar for the time 'A'. According to one exemplary form of the present disclosure, the pause time is set to be equal, but the present disclosure is not limited thereto. In other words, the pause time is variable. ​

[0062] When the camera and radar are operational, the controller 140 can determine whether motion is sensed around the vehicle. Alternatively, when the camera and radar operation has lasted for time 'A', the controller 140 can determine whether the number of times motion was sensed around the vehicle is '0'. When the radar operation has lasted for time 'A', and the controller 140 is unsure whether the number of times motion was sensed around the vehicle is '0', the controller 140 can determine the surrounding conditions as rain or snow outside the vehicle. The controller 140 can determine (maintain) the camera's video recording mode as a periodic recording mode.

[0063] Meanwhile, when the operation of the camera and radar reaches time 'A', and when the controller 140 determines that the number of motions sensed around the vehicle is '0', the controller 140 can control the camera to enter a low-power parking recording mode and perform normal parking video recording operations.

[0064] When the camera and sensor are in a paused state for time 'A', the controller 140 can control the impact detection sensor to sense impacts from around the vehicle. When the camera and sensor (radar) are in a paused state for time 'A', and when the impact detection sensor senses an impact from around the vehicle, after sensing the impact, the controller 140 can wake up the camera and control it to perform video recording for a predetermined time (e.g., 20 seconds). According to an exemplary form of this disclosure, the controller 140 can control the operation of the wipers to ensure visibility at the front and rear of the vehicle, and can set the wiper operation mode according to a periodic recording pattern. Details will be referred to... Figure 3 .

[0065] Figure 3 This is a schematic diagram illustrating the operation of a wiper according to a periodic recording pattern as disclosed herein.

[0066] like Figure 3 As shown, according to the first embodiment, the controller 140 can perform control operations to prevent wiper operation when the periodic recording mode is in the first mode, and to control wiper operation when the periodic recording mode is in the second and third modes, so as to ensure visibility of the front and rear of the vehicle when an impact from around the vehicle is sensed.

[0067] Furthermore, according to the second embodiment, the controller 140 can perform control operations to prevent wiper operation when the periodic recording mode is in the first and second modes, and to control wiper operation when the periodic recording mode is in the third mode, thereby ensuring visibility to the front and rear of the vehicle when an impact from around the vehicle is sensed. The controller 140 operates the wipers in the aforementioned manner, thereby effectively controlling the operation of the wipers, which consumes a large amount of current.

[0068] Figure 4 is a flowchart illustrating a method for recording a video in a vehicle according to one example form of the present disclosure.

[0069] As Figure 4 shown, when the vehicle is parked or stopped, the controller 140 can enter a low-power parking recording mode (S110). The controller 140 can perform a general parking video recording operation (S120) after entering the low-power parking recording mode. In S120, in the general parking video recording operation, the controller 140 can perform a control operation to start the operation of the camera after sensing motion, and perform the operation of the camera for a certain time (e.g., 10 seconds) after the motion ends.

[0070] In addition, the controller 140 can determine whether motion around the vehicle is sensed for more than a first time (e.g., 10 minutes) (S130). When it is determined in S130 that motion around the vehicle is sensed for less than the first time (No), the controller 140 can determine the video recording mode of the camera as the low-power parking recording mode, and can perform the general parking video recording operation (S110 and S120).

[0071] When it is determined in S130 that motion around the vehicle is sensed for more than the first time (Yes), the controller 140 can determine the surrounding situation as a situation in which it is raining or snowing outside the vehicle, can determine the video recording mode of the camera as a periodic recording mode. The controller 140 can control the camera and the sensor to repeatedly operate and pause (S140). As an example in S140, when the operation of the camera and the sensor (radar) is performed (e.g., when the operation of the camera and the sensor is performed for a time 'A' (e.g., 10 seconds)), the controller 140 can determine whether motion around the vehicle is sensed. According to another form, when the operation of the camera and the radar is performed for the time 'A', the controller 140 can determine whether the number of motions sensed around the vehicle is '0' (S150).

[0072] When the controller 150 cannot determine that the number of motions sensed around the vehicle is '0' in S150 (No), the controller 140 can determine the surrounding situation as a situation in which it is raining or snowing outside the vehicle, and can control the video recording mode of the camera as the periodic recording mode. Meanwhile, when the controller 140 determines that the number of motions sensed around the vehicle is '0' (Yes), the controller 140 can control the camera to enter the low-power parking recording mode and perform the general parking video recording operation (S110 and S120).

[0073] When the camera and the sensor are in the suspend state (for example, when the camera and the sensor are in the suspend state for a time 'A' (for example, 10 seconds)), the controller 140 can control the impact detection sensor to sense an impact from the surroundings of the vehicle (S160). When the camera and the sensor (radar) are in the suspend state for the time 'A' in S160, and when the impact detection sensor senses an impact from the surroundings of the vehicle (Yes), after sensing the impact, the controller 140 can wake up the camera and control the camera to perform a video recording operation for a predetermined time (for example, 20 seconds) (S170). When no impact from the surroundings of the vehicle is sensed in S160 (No), the controller 140 can perform the periodic recording mode (S140).

[0074] The controller 140 can determine whether the ignition is on or whether the remaining level of the battery is less than a threshold (S180). When the ignition is on or the remaining level of the battery is less than the threshold in S180 (Yes), the controller 140 releases the low-power parking recording mode (S190). When the ignition is not on or the remaining level of the battery exceeds the threshold in S180 (No), the controller 140 can perform a control operation to re-enter the low-power parking recording mode (S110).

[0075] Figure 5 FIG. 17 is a flowchart illustrating a method for recording a video in a vehicle according to another form of the present disclosure.

[0076] As Figure 5 indicated, when the vehicle is parked or stopped, the controller 140 can enter the low-power parking recording mode (S210). The controller 140 can perform a general parking video recording operation after entering the low-power parking recording mode (S220). In the general parking video recording operation in S220, the controller 140 can perform a control operation to start the operation of the camera after sensing motion, and perform the operation of the camera for a certain time (for example, 10 seconds) after the motion ends.

[0077] In addition, the controller 140 can determine whether motion from the surroundings of the vehicle is sensed for more than a second time (for example, 5 minutes) (S230). When it is determined that motion from the surroundings of the vehicle is sensed for less than the second time in S230 (No), the controller 140 can determine the video recording mode of the camera to be the low-power parking recording mode, and can perform the general parking video recording operation (S210 and S220).

[0078] When it is determined in S230 that the motion around the vehicle is sensed for more than the second time (Yes), the controller 140 can determine whether the rain sensor senses the water droplets on the surface of the vehicle (S240). When it is determined in S240 that the rain sensor senses the water droplets on the surface of the vehicle (Yes), the controller 140 can determine the video recording mode of the camera as the periodic recording mode, and can perform a control operation to repeat the operation and pause the camera and the sensor (S250). In S250, as the amount or change of the water droplets on the surface of the vehicle sensed by the rain sensor increases, the controller 140 can reduce the operation time of the camera and the radar, and can control the camera and the radar to operate for the reduced operation time. Details thereof can be understood by referring to the description of Figure 2 When it is not determined that the water droplets are sensed in S240, the controller 140 can perform S210.

[0079] While the camera and the radar are in the operation state, the controller 140 can determine whether the motion around the vehicle is sensed. According to one exemplary form, the controller 140 can determine whether the number of the motions sensed around the vehicle is '0' (S260). When the controller 140 cannot determine that the number of the motions sensed around the vehicle is '0' in S260 (No), the controller 140 can determine the surrounding situation as a situation in which it rains or snows outside the vehicle, and can determine (keep) the video recording mode of the camera as the periodic recording mode (S250).

[0080] Meanwhile, when the controller 140 determines that the number of the motions sensed around the vehicle during the radar operation is '0' in S260, the controller 140 can enter the low-power consumption parking recording mode and can control the camera to perform the general parking video recording operation (S210 and S220).

[0081] While the camera and the sensor are in the pause state, the controller 140 can control the impact detection sensor to sense the impact from around the vehicle. When the camera and the sensor are in the pause state, and when the impact detection sensor senses the impact from around the vehicle (S270), the controller 140 can wake up the camera and control the camera to perform the video recording operation for a predetermined time (e.g., 20 seconds) (S280). The controller 140 can control the wiper to operate in the video recording operation to secure the view of the front and rear of the vehicle, and can set the wiper operation mode according to the periodic recording mode in S280. Details of the wiper operation mode can be understood by referring to Figure 3 .

[0082] The controller 140 can determine whether the ignition is on or whether the remaining level of the battery is less than a threshold (S290). When the ignition is on or the remaining level of the battery is less than the threshold in S290, the controller 140 can release the low-power parking recording mode (S300). When the ignition is not on or the remaining level of the battery exceeds the threshold (No), the controller 140 can perform a control operation to re-enter the low-power parking recording mode (S210).

[0083] Figure 6 is a block diagram illustrating a computing system for performing a method according to one example form of the present disclosure.

[0084] Referring to Figure 6 , the computing system 1000 can include at least one processor 1100, a memory 1300, a user interface input device 1400, a user interface output device 1500, a storage device 1600, and a network interface 1700, which are connected to each other by a bus 1200.

[0085] The processor 1100 can be a central processing unit (CPU) or a semiconductor device for processing instructions stored in the memory 1300 and / or the storage device 1600. Each of the memory 1300 and the storage device 1600 can include various types of volatile or non-volatile storage media. For example, the memory 1300 can include read-only memory (ROM, see 1310) and random access memory (RAM, see 1320).
