[0010] Hereinafter, the present embodiment (embodiment of the present invention) will be described with reference to the drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted.

[0011] [First embodiment] Fig. 1 is a diagram showing an example of the system configuration of a vehicle monitoring system according to a first embodiment. The vehicle monitoring system 1 is mounted on a vehicle 10 such as an automobile, and records video captured by a camera around the vehicle in response to an impact while the vehicle is parked. In the example of Fig. 1, the vehicle monitoring system 1 includes a multimedia device 110, a monitoring control device 100, a battery sensor 120, a video output device 130, and a recording device 140.

[0012] The multimedia device 110 is an electronic control device (first electronic control device) having a car navigation function, such as a navigation ECU (Electronic Control Unit) or a multimedia ECU. The multimedia device 110 according to this embodiment includes an acceleration sensor 111 and a multimedia processing unit 112.

[0013] The acceleration sensor 111 is a sensor that measures acceleration and operates on a constantly supplied power source (hereinafter referred to as a first power source 12) that is constantly supplied from the battery 11 of the vehicle 10. The acceleration sensor 111 may be included in an inertial measurement unit (IMU) that includes an acceleration sensor and an angular velocity (gyro) sensor, for example.

[0014] The multimedia processing unit 112 provides a navigation function using the acceleration sensor 111 when a second power source 13 (such as an accessory power source of the vehicle 10) different from the first power source is supplied.

[0015] Furthermore, multimedia processing unit 112 has setting unit 113 that changes the setting of acceleration sensor 111 to a setting for parking when vehicle 10 is parked. For example, setting unit 113 performs a setting on acceleration sensor 111 that is necessary for detecting an impact to vehicle 10. Furthermore, when acceleration sensor 111 is included in an inertial measurement unit or the like, setting unit 113 may stop the operation of the angular velocity sensor out of acceleration sensor 111 and an angular velocity sensor included in the inertial measurement unit.

[0016] The monitoring control device 100 is an electronic control device that operates on a first power source that is constantly supplied from a battery 11 of the vehicle 10. Preferably, the monitoring control device 100 is realized by a small-scale microcomputer with low power consumption and a storage medium that stores a program for the monitoring control device 100. In the example of Fig. 1, the monitoring control device 100 realizes a monitoring control unit 101, a battery monitoring unit 102, etc. by the microcomputer included in the monitoring control device 100 executing a predetermined program.

[0017] The monitoring control unit 101 operates on a first power supply, and when the acceleration sensor 111 detects acceleration equal to or greater than a predetermined value while the vehicle 10 is parked, it activates the video output device 130 and the recording device 140. As a result, the video output device 130 and the recording device 140 record images of the area around the vehicle 10.

[0018] The battery monitoring unit 102 estimates the remaining capacity of the battery 11 based on the state of the battery 11 detected by the battery sensor 120. For example, the battery sensor 120 transmits information about the battery 11, such as the charging current, discharging current, voltage, or temperature of the battery 11, to the battery monitoring unit 102 as the state of the battery 11. Furthermore, the battery monitoring unit 102 calculates the remaining capacity (usable battery capacity) of the battery 11 based on the state of the battery 11 received from the battery sensor 120.

[0019] For example, when the acceleration sensor 111 detects an impact of a predetermined value or more while the vehicle 10 is parked, the battery monitoring unit 102 calculates the current remaining charge of the battery 11 by, for example, one of the following methods.

[0020] (Method 1) While the vehicle 10 is parked, the battery sensor 120 is stopped, and when the vehicle 10 starts to park, the battery monitoring unit 102 acquires the state of the battery 11 from the battery sensor 120. Furthermore, if the acceleration sensor 111 detects acceleration equal to or greater than a predetermined value while the vehicle 10 is parked, the battery monitoring unit 102 calculates the current remaining battery charge of the battery 11 based on the remaining battery charge at the time when parking started, the elapsed time since parking started, the power consumption during parking, etc.

[0021] (Method 2) While the vehicle 10 is parked, the battery sensor 120 is stopped, and when the acceleration sensor 111 detects acceleration equal to or greater than a predetermined value while the vehicle is parked, the battery monitoring unit 102 activates the battery sensor 120 and acquires the state of the battery 11. Furthermore, the battery monitoring unit 102 calculates the current remaining battery capacity of the battery 11 based on the acquired state of the battery 11.

[0022] (Method 3) The battery sensor 120, which consumes little power, is kept active at all times even while the vehicle 10 is parked. When the acceleration sensor 111 detects acceleration equal to or greater than a predetermined value while the vehicle 10 is parked, the battery monitoring unit 102 acquires the state of the battery 11 from the battery sensor 120 and calculates the current remaining battery charge of the battery 11 based on the acquired state of the battery 11. Note that the battery monitoring unit 102 may acquire the current remaining battery charge of the battery 11 by a method other than methods 1 to 3.

[0023] The video output device 130 is a device that outputs a video of the periphery of the vehicle 10. As an example, the video output device 130 is an electronic control device such as a PVM (Panoramic View Monitor) ECU (Electronic Control Unit) that generates a video of the periphery of the vehicle 10 using a front image, a rear image, a right side image, a left side image, etc. captured by a plurality of cameras. The video output device 130 is an example of a third electronic control device. As another example, the video output device 130 may be one or more cameras that capture images of the periphery of the vehicle 10.

[0024] The recording device 140 is an electronic control device (fourth electronic control device) that records the video of the surroundings of the vehicle 10 output by the video output device 130 in a storage device 141 or the like.

[0025] The video output device 130 and the recording device 140 stop operating while the vehicle 10 is parked, and start operating in response to a start-up signal or the like from the monitoring control device 100. The started video output device 130 and the recording device 140 record video around the vehicle 10 for a predetermined period of time, and then stop operating again.

[0026] 1 is an example. For example, as shown in FIG. 2, the monitoring control device 100 may not have the battery monitoring unit 102 and may acquire the current battery capacity of the battery 11 from a battery sensor 120. The recording device 140 may be included in the video output device 130. The recording device 140 may also be included in the multimedia device 110, the monitoring control device 100, or the like.

[0027] <Hardware configuration> (Hardware configuration of monitoring and control device) The monitoring and control device 100 has, for example, a computer hardware configuration as shown in FIG.

[0028] Fig. 3 is a diagram illustrating an example of the hardware configuration of a computer according to an embodiment. In the example of Fig. 3, a computer 300 includes a CPU (Central Processing Unit) 311, a memory 312, a storage device 313, a communication I / F (Interface) 302, an input / output I / F 303, a bus 304, and the like.

[0029] The CPU 311 is a processor that performs various processes by executing predetermined programs stored in a storage medium such as the memory 312 or the storage device 313. The memory 312 includes, for example, a random access memory (RAM) that is a volatile memory used as a work area or the like for the CPU 311, and a read-only memory (ROM) that pre-stores programs for starting up the CPU 311, etc. The storage device 313 is, for example, a large-capacity non-volatile storage device such as a flash ROM. Note that the CPU 311, memory 312, storage device 313, etc. may be realized by a single device such as the microcomputer 301.

[0030] The communication I / F 302 includes, for example, a network interface for connecting the computer 300 to an in-vehicle network of the vehicle 10 to communicate with other electronic control units (ECUs). The input / output I / F 303 is an interface for connecting an external device to the computer 300. For example, the acceleration sensor 111, the battery sensor 120, etc. are connected to the input / output I / F 303 of the computer 300 provided in the monitoring control device 100. The bus 304 is connected to each of the above components and transmits, for example, address signals, data signals, various control signals, etc.

[0031] (Hardware configuration of multimedia devices) The multimedia device 110 includes, for example, an acceleration sensor 111 that operates on a first power source that is constantly supplied from a battery 11, and a computer 300 as shown in FIG.

[0032] The computer 300 included in the multimedia device 110 operates when a second power source 13 different from the first power source is supplied, and for example, an acceleration sensor 111 is connected to the input / output I / F 303. The computer 300 included in the multimedia device 110 also implements the multimedia processing unit 112, setting unit 113, etc. described in FIG. 1 by executing a program stored in a storage medium such as a storage device 313 or a memory 312.

[0033] (Hardware configuration of video output device) 3, the video output device 130 has one or more cameras connected to the input / output I / F 303, which capture images of the periphery of the vehicle 10. The video output device 130 is also connected to a first power source 12 that is constantly supplied with power from a battery 11, and has a power switch that supplies power to the computer 300 included in the video output device 130 in response to a start-up signal from the monitoring control device 100, etc.

[0034] (Hardware configuration of recording device) As an example, recording device 140 has the hardware configuration of computer 300 equipped with storage device 141. In this case, storage device 141 and storage device 313 may be the same device. As another example, recording device 140 may be an external storage device equipped with storage device 141. Recording device 140 is connected to first power source 12 that is constantly supplied with power from battery 11, and has a power switch that supplies power to computer 300 and the like equipped in recording device 140 in response to a start-up signal from monitoring control device 100, etc.

[0035] (battery and battery sensor) The battery 11 is a battery provided in the vehicle 10. The battery sensor 120 is attached to the battery 11 so as to detect the state of the battery 11, for example.

[0036] <Processing flow> Next, the processing flow of the vehicle monitoring method according to the first embodiment will be described.

[0037] (Acceleration sensor setting process 1) 4 is a flowchart (1) showing an example of the acceleration sensor setting process according to the first embodiment. This process shows an example of the acceleration sensor setting process executed by the vehicle monitoring system 1 when the second power supply 13 (e.g., an accessory power supply) of the vehicle 10 is turned on.

[0038] In step S401, when the second power supply 13 of the vehicle 10 is turned on, the vehicle monitoring system 1 executes the processes from step S402 onwards.

[0039] In step S402, when multimedia processing unit 112 is started up by second power source 13, setting unit 113 determines whether or not this is the first start-up. For example, if initial settings have not been made to acceleration sensor 111 in multimedia device 110, setting unit 113 determines that this is the first start-up. If this is the first start-up, setting unit 113 shifts the process to step S403. On the other hand, if this is not the first start-up, setting unit 113 shifts the process to step S404.

[0040] In step S403, the setting unit 113 performs initial settings on the acceleration sensor 111. For example, the setting unit 113 writes into the acceleration sensor 111 settings for the navigation function and settings for parking.

[0041] In step S404, the setting unit 113 sets the acceleration sensor 111 for the navigation function.

[0042] In step S405, the acceleration sensor 111 starts providing sensor information for the navigation function to the multimedia processing unit 112. This allows the multimedia processing unit 112 to use the sensor information provided by the acceleration sensor 111 for positioning the vehicle 10.

[0043] (Acceleration sensor setting process 2) 5 is a flowchart (2) showing an example of the acceleration sensor setting process according to the first embodiment. This process shows an example of the acceleration sensor setting process executed by the vehicle monitoring system 1 when the second power supply 13 (e.g., accessory power supply) of the vehicle 10 is turned off.

[0044] In step S501, when the second power supply 13 of the vehicle 10 is turned off, the vehicle monitoring system 1 executes the processes from step S502 onwards.

[0045] In step S502, the setting unit 113 switches the setting of the acceleration sensor 111 to the setting for parking.

[0046] In step S503, the multimedia device 110 turns off the power to the multimedia processing unit 112.

[0047] In step S504, the acceleration sensor 111 starts providing the monitoring control device 100 with sensor information for parking.

[0048] 4 and 5, the vehicle monitoring system 1 according to the first embodiment is able to detect an impact to the vehicle 10 when parked, using the acceleration sensor 111 provided in the multimedia device 110.

[0049] (Processing when parking) 6 is a flowchart showing an example of processing during parking according to one embodiment. This processing shows an example of processing executed by the vehicle monitoring system 1 when the vehicle 10 is parked. It is assumed that at the start of the processing shown in FIG. 6, the vehicle monitoring system 1 has already executed the acceleration sensor setting processing described in FIG. 5.

[0050] In step S601, when the acceleration sensor 111 detects an impact while the vehicle 10 is parked, the vehicle monitoring system 1 executes the processes from step S602 onwards.

[0051] In step S602, the monitoring control unit 101 of the monitoring control device 100 determines whether the detected acceleration exceeds a set value (is equal to or greater than a predetermined value). Here, the set value is a value that is set in advance in the monitoring control unit 101 and is used by the vehicle monitoring system 1 to determine whether or not to record video around the vehicle 10.

[0052] If the detected acceleration exceeds the set value, the monitoring control unit 101 shifts the process to step S603. On the other hand, if the detected acceleration does not exceed the set value, the monitoring control unit 101 stops the execution of the process from step S603 onwards and ends the process in FIG.

[0053] In step S603, the monitoring control device 100 checks the remaining battery charge of the battery 11 of the vehicle 10. For example, if the detected acceleration exceeds a set value, the monitoring control unit 101 of the monitoring control device 100 inquires about the remaining battery charge from the battery monitoring unit 102. In response, the battery monitoring unit 102 calculates the current remaining battery charge of the battery 11 by one of the above-mentioned methods 1 to 3, and notifies the monitoring control unit 101 of the calculated remaining battery charge.

[0054] As another example, when the detected acceleration exceeds a set value, the battery monitoring unit 102 of the monitoring control device 100 may calculate the current remaining battery capacity of the battery 11 and notify the monitoring control unit 101 of the calculated remaining battery capacity.

[0055] In step S604, the monitoring control unit 101 of the monitoring control device 100 determines whether the next engine start is possible even if recording is performed with the current remaining battery charge. For example, the monitoring control unit 101 stores in advance the remaining battery charge sufficient to start the engine of the vehicle 10 and the battery capacity consumed in one recording. Furthermore, if the value obtained by subtracting the battery capacity consumed in one recording from the current remaining battery charge is equal to or greater than the remaining battery charge sufficient to start the engine of the vehicle 10, the monitoring control unit 101 determines that the next engine start is possible even if recording is performed.

[0056] If the next engine start is possible even if the recording is performed, the monitoring control unit 101 shifts the process to step S605. On the other hand, if the next engine start is not possible if the recording is performed, the monitoring control unit 101 shifts the process to step S608.

[0057] In step S605, the monitoring control unit 101 of the monitoring control device 100 starts up the video output device 130 and the recording device 140. For example, the monitoring control unit 101 outputs a start-up signal to the video output device and the recording device 140.

[0058] In step S606, the video output device 130 and the recording device 140 record video of the surroundings of the vehicle 10 for a predetermined time. For example, the recording device 140 stores the video data of the surroundings of the vehicle 10 output by the video output device 130 in the storage device 141 with a timestamp or the like.

[0059] In step S607, after the vehicle surveillance system 1 has finished recording, it stops the video output device 130 and the recording device 140. For example, the surveillance control unit 101 of the surveillance control device 100 may disable (negate) the activation signal that was enabled (asserted) in step S605, thereby stopping the video output device 130 and the recording device 140. Alternatively, the video output device 130 and the recording device 140 may autonomously stop operating after the video recording has finished.

[0060] On the other hand, when the process moves from step S604 to step S608, the monitoring control unit 101 of the monitoring control device 100 records only the detection of an impact and stops recording. For example, the monitoring control unit 101 ends the process in Fig. 6 without executing the processes of steps S605 to S607. This process enables the vehicle monitoring system 1 to prevent the battery from running out while the vehicle is parked.

[0061] Preferably, the monitoring control unit 101 stores data indicating that an impact has been detected, and causes the recording device 140 to store the stored data the next time the recording device 140 is started up.

[0062] According to the first embodiment, the processing of FIGS. 4 to 6 makes it possible to realize a vehicle monitoring system using the acceleration sensor 111 provided in the multimedia device 110 while suppressing power consumption of the battery 11 of the vehicle 10 while the vehicle is parked.

[0063] [Second embodiment] In the first embodiment, an example has been described in which the vehicle monitoring system 1 is realized using the acceleration sensor 111 for navigation functions (positioning) provided in the multimedia device 110. However, this is just an example, and the vehicle monitoring system 1 according to this embodiment may also use other acceleration sensors provided in the vehicle 10.

[0064] For example, if the vehicle 10 has an intrusion detection system that detects intrusion into the vehicle 10, the vehicle monitoring system 1 may be realized using an acceleration sensor for the intrusion detection system.

[0065] <System configuration> Fig. 7 is a diagram showing an example of the system configuration of a vehicle monitoring system 1 according to the second embodiment. In the example of Fig. 7, the vehicle monitoring system 1 has an intrusion detection device 702 and an acceleration sensor 701 for the intrusion detection system. Note that the configurations of the monitoring control device 100, battery sensor 120, video output device 130, recording device 140, battery 11, etc. included in the vehicle monitoring system 1 according to the second embodiment may be similar to the configurations of the vehicle monitoring system 1 according to the first embodiment.

[0066] The intrusion detection device 702 is an electronic control device (second electronic control device) such as a body ECU that provides an intrusion detection function that issues an alarm with sound and light when it detects an unauthorized intrusion into the vehicle 10 using an acceleration sensor 111, an ultrasonic sensor, etc.

[0067] The acceleration sensor 701 for the intrusion detection system is basically configured to detect the acceleration of the vehicle 10 in order to detect intruders even when the vehicle 10 is parked. Therefore, the vehicle monitoring system 1 according to the second embodiment does not need to include, for example, the setting unit 113 that performs the setting process for the acceleration sensor described in Figures 4 and 5. However, this is not limiting, and the intrusion detection device 702 may include, as necessary, the setting unit 113 that changes the setting of the acceleration sensor 701 when the vehicle 10 is parked.

[0068] The acceleration sensor 701 is an acceleration sensor that is pre-installed in the vehicle 10 for, for example, an intrusion detection system. The acceleration sensor 701 is connected to a first power source 12 that is constantly supplied with power from a battery 11 so that it can detect an impact to the vehicle 10, for example, even when the vehicle 10 is parked. The acceleration sensor 701 according to this embodiment is also configured to output sensor information indicating the detected acceleration to the monitoring control device 100 in addition to the intrusion detection device 702.

[0069] 7 is an example. For example, the monitoring control device 100 according to the second embodiment may not have the battery monitoring unit 102, as in the first embodiment, and may acquire the current battery capacity of the battery 11 from the battery sensor 120. The recording device 140 may be included in the video output device 130. The recording device 140 may be included in the multimedia device 110, the monitoring control device 100, or the like.

[0070] <Processing flow> When the vehicle 10 is parked, the vehicle monitoring system 1 according to the second embodiment executes the parking process described in Fig. 6 using the acceleration sensor 701 described in Fig. 7 instead of the acceleration sensor 111. For example, in step S601, when the acceleration sensor 701 detects an impact while the vehicle 10 is parked, the vehicle monitoring system 1 according to the second embodiment executes the processes of steps S602 to S608. Note that the processes of steps S602 to S608 may be the same as those in the first embodiment.

[0071] In this way, the vehicle monitoring system 1 according to the present invention may use various acceleration sensors provided in the vehicle 10 to detect impacts (acceleration) while the vehicle 10 is parked.

[0072] As described above, according to each embodiment of the present invention, it is possible to suppress the power consumption of the vehicle battery while the vehicle is parked, and to realize the vehicle monitoring system 1 using the acceleration sensor provided in the vehicle. Furthermore, according to each embodiment of the present invention, it is possible to eliminate the dedicated acceleration sensor of the vehicle monitoring system 1.

[0073] Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications, changes, or applications are possible within the scope of the gist of the present invention described in the claims.
