Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a dashcam and a fuel-powered vehicle. Background Technology

[0002] As a key security device for intelligent connected vehicles, dashcams need to continuously monitor the environmental conditions both when the vehicle is running and stationary.

[0003] In new energy vehicles, when the vehicle is parked and turned off, the large power battery equipped in the new energy vehicle can automatically charge the 12V small battery, so that the new energy vehicle can still maintain power supply to equipment such as the driving recorder when the engine is off, providing an all-weather online monitoring function.

[0004] However, the power supply method of gasoline vehicles differs from that of new energy vehicles. When a gasoline vehicle is turned off, the main battery does not work, and the energy of the 12V small battery is limited. If it continues to power the dashcam, it is easy to run out of power, causing the gasoline vehicle to fail to start and resulting in high maintenance costs. Therefore, current gasoline vehicles generally adopt a "work when ignited, power off when turned off" power management method, thus failing to provide 24 / 7 online monitoring capabilities. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a dashcam and a fuel vehicle, which does not require the fuel vehicle to be constantly ignited, can achieve all-weather online monitoring function, and effectively reduces power consumption.

[0006] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows: In a first aspect, the present invention provides a dashcam, comprising a first main control module, a second main control module, a communication module, and an external battery. The first main control module is communicatively connected to the second main control module, the communication module is communicatively connected to both the first main control module and the second main control module, and the external battery is electrically connected to the first main control module. The first main control module is used to monitor the status of the fuel vehicle and acquire vehicle motion data. When the fuel vehicle is in the ignition state, it charges the external battery based on the electrical energy provided by the fuel vehicle and supplies power to the second main control module, and sends the acquired vehicle motion data to the second main control module. When the fuel vehicle is in the off state, it supplies power through the external battery and disconnects the power to the second main control module, and communicates with the remote control system through the communication module. The second main control module is used to collect and store images of the surrounding environment when the fuel vehicle is in the ignition state, and send them to the remote control system through the communication module.

[0007] In an optional implementation, the first main control module is further configured to determine whether to supply power to the second main control module based on the acquired liveness monitoring information or the vehicle motion data when the fuel vehicle is in a turned-off state and the second main control module is in a power-off state.

[0008] In an optional implementation, the first main control module is used to supply power to the second main control module when the liveness detection information indicates the presence of a live body, so that the second main control module can collect and store the current surrounding environment image of the fuel vehicle; when the liveness detection information indicates the absence of a live body, the first main control module is controlled to remain in a power-off state.

[0009] In an optional implementation, the vehicle motion data includes vehicle speed information. The first main control module is used to supply power to the second main control module when the vehicle speed information is not 0, so that the second main control module can collect and store the current surrounding environment image of the fuel vehicle.

[0010] In an optional implementation, the first main control module is further configured to start timing after powering on the second main control module, and to power off the second main control module after the timing duration reaches a preset duration.

[0011] In an optional implementation, the second main control module is further configured to detect vehicle motion data sent by the first main control module when the fuel vehicle is in the ignition state, and send alarm information to the remote control system when a collision event is detected.

[0012] In an optional implementation, the first main control module is used to report the acquired vehicle motion data to the remote control system through the communication module when the fuel vehicle is in a turned-off state. The second main control module is used to report the vehicle motion data sent by the first main control module to the remote control system through the communication module when the fuel vehicle is in the ignition state.

[0013] In an optional implementation, the first main control module includes an MCU, an inertial navigation unit, a status monitoring unit, and an energy control unit. The inertial navigation unit, the status monitoring unit, and the energy control unit are all electrically connected to the MCU, and the energy control unit is also electrically connected to the external battery. The inertial navigation unit is used to acquire the vehicle motion data and send it to the second main control module through the MCU; The status monitoring unit is used to monitor the status of the fuel vehicle and send the status of the fuel vehicle to the MCU; The energy control unit is used to charge the external battery and supply power to the second main control module under the control of the MCU when the fuel vehicle is in the ignition state; and to supply power to the second main control module under the control of the MCU when the fuel vehicle is in the off state.

[0014] In an optional implementation, the second main control module includes an embedded SOC, an image acquisition unit, a disk management unit, and a collision detection unit, wherein the image acquisition unit, the disk management unit, and the collision detection unit are all electrically connected to the embedded SOC. The image acquisition unit is used to acquire images of the surrounding environment of the fuel vehicle; The embedded SOC is used to store the surrounding environment image through the disk management unit; The embedded SOC is also used to acquire vehicle motion data sent by the first main control module, and to perform detection based on the vehicle motion data through the collision detection unit. When a collision event is detected, an alarm message is sent to the remote control system.

[0015] Secondly, the present invention provides a fuel-powered vehicle, the fuel-powered vehicle including the driving recorder described in any of the foregoing embodiments.

[0016] The present invention provides a dashcam and a gasoline-powered vehicle. The dashcam includes a first main control module, a second main control module, a communication module, and an external battery. The first main control module is communicatively connected to the second main control module, and the communication module is communicatively connected to both the first and second main control modules. The external battery is electrically connected to the first main control module. The first main control module is used to monitor the status of the gasoline-powered vehicle and acquire vehicle motion data. When the gasoline-powered vehicle is ignited, it charges the external battery based on the electrical energy provided by the gasoline-powered vehicle and supplies power to the second main control module, sending the acquired vehicle motion data to the second main control module. When the gasoline-powered vehicle is off, it supplies power through the external battery and disconnects power to the second main control module, communicating with the remote control system through the communication module. The second main control module is used to collect and store images of the surrounding environment when the gasoline-powered vehicle is ignited, communicating with the remote control system through the communication module. This invention features a system where the fuel vehicle powers the system when it is ignited and an external battery powers the system when it is off. The first main control module can acquire vehicle motion data both when the fuel vehicle is ignited and when it is off, while the second main control module is activated only when the fuel vehicle is ignited. Furthermore, the dashcam can communicate with the remote control system both when the fuel vehicle is ignited and when it is off. Therefore, the fuel vehicle does not need to be constantly ignited, and the system can achieve 24 / 7 online monitoring, effectively reducing power consumption.

[0024] Please refer to Figure 1 This is a structural block diagram of a dashcam 100 provided in an embodiment of the present invention. The dashcam 100 includes a first main control module 110, a second main control module 120, a communication module 130, and an external battery 140. The first main control module 110 is communicatively connected to the second main control module 120, and the communication module 130 is communicatively connected to both the first main control module 110 and the second main control module 120. The external battery 140 is electrically connected to the first main control module 110, and either the first main control module 110 or the second main control module 120 can communicate with the remote control system 200 via the communication module 130.

[0025] The first main control module 110 and the second main control module 120 can interact via a serial port; the communication module 130 can be a low-power 4G / 5G module, connected to the remote control system 200 via a 4G / 5G network. The remote control system 200 can include at least one of a monitoring and control platform, a cloud storage server, and a client; the monitoring and control platform can be a traffic management center platform, capable of unified management and monitoring of various traffic equipment; various data reported by the first main control module 110 or the second main control module 120 (such as vehicle motion data, image data, alarm information, etc.) can be stored on the cloud storage server, and this data can also be visualized on the corresponding client for customer viewing.

[0026] In this embodiment, the first main control module 110 is used to monitor the status of the fuel vehicle and acquire vehicle motion data. When the fuel vehicle is in the ignition state, it charges the external battery 140 based on the electrical energy provided by the fuel vehicle and supplies power to the second main control module 120, and sends the acquired vehicle motion data to the second main control module 120. When the fuel vehicle is in the off state, it supplies power through the external battery 140 and disconnects the power to the second main control module 120, and communicates with the remote control system 200 through the communication module 130. The second main control module 120 is used to collect and store images of the surrounding environment when the fuel vehicle is in the ignition state, and communicates with the remote control system 200 through the communication module 130.

[0027] In other words, when the fuel vehicle is ignited, the dashcam 100 is powered by the fuel vehicle, the first main control module 110 is online, acquires vehicle motion data such as vehicle location information, vehicle speed information, and vehicle acceleration information, and sends it to the second main control module 120; the second main control module 120 is online, collects images of the surrounding environment of the fuel vehicle and stores them on the disk, and the communication module 130 is controlled by the second main control module 120 to connect to the remote control system 200, and the second main control module 120 reports data to the remote control system 200 to realize remote monitoring of the fuel vehicle in the ignition state.

[0028] For example, when the fuel vehicle is in the ignition state, the second main control module 120 can report the vehicle motion data sent by the first main control module 110 to the remote control system 200 through the communication module 130.

[0029] When the fuel vehicle is turned off, the dashcam 100 is powered by the external battery 140. The first main control module 110 is online, while the second main control module 120 is offline when it loses power. The communication module 130 is connected to the remote control system 200 by the first main control module 110. The first main control module 110 reports data to the remote control system 200 to realize remote monitoring of the fuel vehicle when it is turned off. The first main control module 110 will send the vehicle status information, such as vehicle location information, vehicle speed information, and vehicle acceleration information, to the remote control system 200 through the communication module 130 at regular intervals.

[0030] For example, when the fuel vehicle is turned off, the first main control module 110 can report vehicle motion data, such as vehicle position information, vehicle speed information, and vehicle acceleration information, to the remote control system 200 via the communication module 130. To further save power consumption, the first main control module 110 can report data at regular intervals.

[0031] As can be seen, the embodiments of the present invention are powered by the fuel vehicle when the fuel vehicle is ignited and by an external battery when the fuel vehicle is turned off. The first main control module can acquire vehicle motion data when the fuel vehicle is ignited and turned off, while the second main control module is only activated when the fuel vehicle is ignited. Furthermore, the driving recorder can communicate with the remote control system when the fuel vehicle is ignited and turned off. Therefore, the fuel vehicle does not need to be in an ignition state at all times, and the all-weather online monitoring function can be achieved, which also effectively reduces power consumption.

[0032] In one embodiment, the first main control module 110 is further configured to determine whether to supply power to the second main control module 120 based on the acquired liveness monitoring information or vehicle motion data when the fuel vehicle is in a turned-off state and the second main control module 120 is in a power-off state.

[0033] In this embodiment, liveness detection information can be collected using a PIR (Passive Infrared) sensor. Liveness detection information indicates whether there are any living beings around the fuel-powered vehicle, i.e., whether any living person or object is approaching the fuel-powered vehicle.

[0034] In one embodiment, the first main control module 110 is specifically used to supply power to the second main control module 120 when the liveness detection information indicates the presence of a live body, so that the second main control module 120 can collect and store the current surrounding environment image of the fuel vehicle; when the liveness detection information indicates the absence of a live body, the second main control module 120 is controlled to remain in a power-off state.

[0035] In other words, when the PIR sensor detects a living person / object, the second main control module 120 will be brought online under the control of the first main control module 110 and will collect and store images of the current surrounding environment of the fuel vehicle; when the PIR sensor does not detect a living person / object, the second main control module 120 will remain in a power-off (offline) state. This allows for on-demand image acquisition triggered by the PIR sensor even when the fuel vehicle is off, avoiding unnecessary power consumption by preventing the second main control module 120 from being idle.

[0036] In this embodiment, when the fuel vehicle is in a turned-off state and the second main control module 120 is in a power-off state, the first main control module 110 can determine whether the fuel vehicle has experienced a collision event based on the acquired vehicle motion data, and thus determine whether it is necessary to control the second main control module 120 to go online to collect and store the current surrounding environment image.

[0037] In one embodiment, the vehicle motion data includes vehicle speed information. Specifically, the first main control module 110 is used to supply power to the second main control module 120 when the vehicle speed information is not 0, so that the second main control module 120 can collect and store the current surrounding environment image of the fuel vehicle.

[0038] In this embodiment, when the acquired vehicle speed information is not zero, it indicates that the fuel vehicle has experienced an external collision, and the first main control module 110 needs to control the second main control module 120 to go online, collect images of the surrounding environment, and store them. In this way, even when the fuel vehicle is off, the second main control module 120 can be triggered by a collision event to perform image acquisition, avoiding unnecessary power consumption caused by the second main control module 120 being idle.

[0039] In one embodiment, the first main control module 110 is further configured to start timing after powering on the second main control module 120, and to power off the second main control module 120 after the timing duration reaches a preset duration.

[0040] In this embodiment, after the first main control module 110 determines that an external collision has occurred to the fuel vehicle and controls the second main control module 120 to go online, it will start timing (e.g., countdown N minutes). If the timing duration has not reached the preset duration (countdown N minutes has not been reached), the second main control module 120 will continue to stay online and perform image acquisition and storage. When the timing duration reaches the preset duration (countdown N minutes has been reached), the first main control module 110 will cut off the power to the second main control module 120 in order to save power consumption.

[0041] In one embodiment, the second main control module 120 is also used to detect the vehicle motion data sent by the first main control module 110 when the fuel vehicle is in the ignition state, and to send alarm information to the remote control system 200 when a collision event is detected.

[0042] In this embodiment, the second main control module 120 can calculate the acceleration change and speed change based on the vehicle acceleration information and vehicle speed information sent by the first main control module 110, and detect whether a collision has occurred with the fuel vehicle based on the acceleration change and speed change. When the fuel vehicle is in normal driving condition, it determines whether a collision has occurred based on the acceleration change and speed change. If no collision has occurred, the second main control module 120 performs routine video image data storage; if a collision has occurred, the second main control module 120 can store the collected collision-related video image data and alarm information, and send alarm information to the remote control system 200.

[0043] In one implementation, please refer to Figure 2 The first main control module 110 includes an MCU 1101, an inertial navigation unit 1102, a status monitoring unit 1103, and an energy control unit 1104. The inertial navigation unit 1102, the status monitoring unit 1103, and the energy control unit 1104 are all electrically connected to the MCU 1101. The energy control unit 1104 is also electrically connected to an external battery 140.

[0044] The inertial navigation unit 1102 is used to acquire vehicle motion data and send it to the second main control module 120 through the MCU 1101; the status monitoring unit 1103 is used to monitor the status of the fuel vehicle and send the status of the fuel vehicle to the MCU 1101; the energy control unit 1104 is used to charge the external battery 140 and supply power to the second main control module 120 under the control of the MCU 1101 when the fuel vehicle is in the ignition state; when the fuel vehicle is in the off state, it is powered by the external battery 140 under the control of the MCU 1101 and the second main control module 120 is de-energized.

[0045] In this embodiment, the inertial navigation unit 1102 integrates GNSS (Global Navigation Satellite System) and an inertial measurement system. GNSS provides geographic location information and timing data, while the inertial measurement system provides vehicle angular velocity, acceleration, and speed data along the X, Y, and Z axes. The status monitoring unit 1103 monitors the ignition status, engine shutdown status, power supply I / O status, and 4G / 5G module status of the fuel-powered vehicle. The energy control unit 1104 charges the external battery 140 and supplies power to the second main control module 120 when the fuel-powered vehicle is ignited; when the fuel-powered vehicle is off, the external battery 140 supplies power, and the second main control module 120 is powered off.

[0046] In one implementation, please refer to Figure 3 The second main control module 120 includes an embedded SOC 1201, an image acquisition unit 1202, a disk management unit 1203, and a collision detection unit 1204. The image acquisition unit 1202, the disk management unit 1203, and the collision detection unit 1204 are all electrically connected to the embedded SOC 1201.

[0047] The image acquisition unit 1202 is used to acquire images of the surrounding environment of the fuel vehicle; the embedded SOC 1201 is used to store the images of the surrounding environment through the disk management unit 1203; the embedded SOC 1201 is also used to acquire vehicle motion data sent by the first main control module 110, and to perform detection based on the vehicle motion data through the collision detection unit 1204, and to send alarm information to the remote control system 200 when a collision event is detected.

[0048] In this embodiment, the image acquisition unit 1202 mainly acquires image data from the front camera, left and right cameras, and rear camera to obtain images of the surrounding environment of the fuel vehicle. The disk management unit 1203 mainly manages and stores video images, alarm information, and driving trajectory information. The collision detection unit 1204 mainly performs collision detection (i.e., detects whether a collision event has occurred with the fuel vehicle) based on the vehicle acceleration information and vehicle speed information obtained from the MCU 1101. When a collision event is detected, the embedded SOC 1201 sends alarm information to the remote control system 200 and stores the collision-related video image data and alarm information.

[0049] Below, in conjunction with Figure 4 The working principle of the dashcam 100 provided in this embodiment of the invention will be explained. The MCU 1101 detects the ignition signal. When it determines that the fuel vehicle is in ignition mode, the dashcam 100 is powered by the fuel vehicle, the embedded SOC 1201 is online, it collects images of the surrounding environment and stores them on the disk, and controls the low-power 4G / 5G module to connect to the remote control system 200. The MCU 1101 is online and monitors the system, acquiring vehicle position information, vehicle speed information, etc., collected by the inertial navigation unit 1102, and sending them to the embedded SOC 1201. The embedded SOC 1201 performs collision detection based on vehicle acceleration information and vehicle speed information through the collision detection unit 1204, stores the data according to the collision detection results, and if a collision event is detected, the embedded SOC 1201 will also send alarm information to the remote control system 200.

[0050] When the vehicle is determined to be in a state of being turned off, the dashcam 100 is powered by the external battery 140, the MCU 1101 is online and the embedded SOC 1201 is powered off; the MCU 1101 controls the low-power 4G / 5G module to connect to the remote control system 200, and obtains vehicle position information, vehicle speed information, etc. collected by the inertial navigation unit 1102, and reports them to the remote control system 200 at regular intervals.

[0051] When the gasoline vehicle is off, if the MCU1101 receives a trigger signal from the PIR sensor (i.e., the MCU1101 receives liveness detection information), the MCU1101 will control the embedded SOC1201 to go online, collect images of the surrounding environment, and store them on the disk. When the PIR sensor does not detect a live person, the MCU1101 controls the embedded SOC1201 to power off, and the embedded SOC1201 is in an offline state. At this time, the MCU1101 still reports vehicle location information, vehicle speed information, and other data.

[0052] When a gasoline-powered vehicle is off, if the vehicle speed information obtained by the MCU1101 is not 0 (i.e., an external collision has occurred), the MCU1101 will control the embedded SOC1201 to come online, collect images of the surrounding environment and store them on the disk, and start a countdown of N minutes. If the countdown of N minutes has not been reached, the embedded SOC1201 will continue to collect and store images. If the countdown of N minutes has already elapsed, the embedded SOC1201 will power down to save power consumption.
