Description

TRAILER ADAPTER AND MULTIFUNCTIONAL VIDEO DISPLAYCROSS-REFERENCE TO RELATED APPLICATIONS[0001.1] This application claims the benefit of priority to US Provisional Application No. 63 / 598,797, filed November 14, 2023, the entirety of which is incorporated by reference herein.BACKGROUNDField

[0001] Certain aspects of the present disclosure generally relate to an adapter for connecting video, power, and other data signals between a trailer to a truck, and more particularly to an adapter with a multi-pin configuration that accommodates connections for cameras attached to the trailer in addition to a non-video data connection for the trailer and the truck. Certain aspects further include systems and methods for reducing a number of video display devices within a truck that is configured with driver safety, fleet management and compliance functionality.Background

[0002] When adding cameras to a trailer that need to connect to a DVR (Digital Video Recorder) or Monitor located in the cab of a truck, one needs a means or method to get the video signal into the cab of the truck. It may also be necessary to supply power from the truck to the camera installed at the trailer.

[0003] Existing solutions to these problems include wireless cameras that draw power from the lighting circuit on the trailer. Wired cameras can be added using a dedicated connector and cable that may be added to the truck and trailer. Each existing solution has its own challenges. Wireless cameras require the camera to be paired, usually through a programming procedure, with a receiver on the truck side. Pairing of cameras may be burdensome or prone to errors, especially if trucks are sometimes mated to different trailers. An added drawback to this methodology is that the video signal is often compressed to preserve wireless bandwidth, which leads to a quality loss on the image. As for wired camera solutions, while a dedicated connector and cable for the camera(s) allows for interoperability between trucks and trailers, since most trucks adopt a standardized 7-pin connector for non-video data and power, a second dedicated connector and cable for the camera(s) may be required. This second dedicated connector andcamera may be time consuming to install, and further, its use relies on the driver to make a second cable connection between the truck and trailer, a step than can be easily missed.

[0004] Accordingly, aspects of the present disclosure provide an adapter that can overcome these challenges associated with connecting a truck with a camera or cameras attached to a trailer.SUMMARY

[0005] Certain aspects of the present disclosure generally relate to providing, implementing, and using a novel adapter that plugs into an existing standard trailer harness connector (such as a 7-pin Phillips in the US) and provides a second socket with additional pins (such as a 13- pin Socket). In certain embodiments, to make the installation of this adapter more secure, a system in accordance with the present disclosure may use existing mounting holes (and / or overlapping pattern of mounting holes) for the existing trailer connector to mount the adapter in place using longer mounting hardware (bolts).

[0006] In a typical US configuration, the adapter carries all 7 of the standard electrical circuits along with up to 4 channels of video depending on the wiring configuration in the adapter. These video signals may be carried via industry standard AV connectors, allowing the adapter to work with most commercially available camera systems.

[0007] Such an adapter configured in accordance with the present disclosure may eliminate a need for a secondary cable to be connected by a driver of the vehicle to get video from cameras attached to the trailer, as the second socket with additional pins (e.g. as in a cable having 13 pins on one end) will carry all of the trailer wiring and the power and video signals normally carried by a secondary video cable, all in a single connection. This arrangement reduces the risk that the driver will not fail to connect the video as the process of connecting the video is incorporated into the process of making the standard 7-pin signal pathway connection. In addition, there may be physical, electrical, audible, etc., notifications or other compliance means already implemented regarding the 7-pin connection to a trailer, which may be leveraged to ensure that the trailer electronics are connected before a driver operates a truck connected to the trailer.BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The detailed description set forth below, in connection with the appended drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0015] Fleets (e.g. truck fleet operators) may need to capture video around a trailer of a truck and / or inside of a truck trailer. These camera recordings require installation of cameras on their trailers. Such cameras may provide views into, for example, the valve assembly on a fuel or chemical trailers. Likewise, a camera installed at the rear of the trailer may provide for driver exoneration and driver assistance with regarding vehicles that may be driving behind the truck and trailer.

[0016] In order to capture video from cameras installed on a trailer, the cameras may need a conduit to get the video from the camera to a DVR (Digital Video Recorder), tablet, monitor, or similar video recording or display components located in the cab of the truck. In some configurations, the camera may need a power source, from the tractor (truck, or vehicle). Tractors and trailers are designed to separate from one another, so a non-permanent connection will need to be made to facilitate this video capture.Trailer Adapter

[0017] FIG. 1 shows an adapter for connecting video, power, and other data signals between a cabin of truck to a trailer, in accordance with an embodiment of the present disclosure. The adapter may include a housing (102), as well as a plug attached to the housing at one end (104) through the use of a fixing means (106), which may be bolts, and a 7-pin socket (108) connected to the other end of the housing. FIG. 2 illustrates two adapters and a 13 -way cable (210). The adapter housing is further detailed in FIGS. 3A-3H. Referring first to FIG 3A, the housing (102) includes a hollow space (304) that holds the circuitry for connecting the 7-pin socket to the plug and further includes a relief for a camera signal pathway. Referring to FIG 3C, the hollow space (304) and relief (306) may be seen from a different angle. The plug further includes additional circuitry for connecting cameras to the plug. Referring to FIG. 2, the plug may include a 13-pin socket (212) and additional cables (114) for connecting cameras to the 13-pin socket. A relief (206) for a camera signal pathway is visible on the second adapter that is attached to the other end of the 13-way cable (210), and that may be attached to the trailer.

[0018] The 7-pin socket helps in connecting the truck to the trailer to power the lights, brakes, and other controlling means (such as anti-lock braking system (ABS)) attached to the trailer. In normal operation, the 13-pin socket in the plug (212) is attached to a 13-pin cable (210). The 13-pin cable is attached to the cabin of the vehicle (such as a truck, car, etc.). The wiring for 7- pin socket on the other end of the housing as well as the wiring for cameras is electrically connected with a 13-pin socket. In an embodiment, the wiring configuration for the 7-pin socket includes each wire for ground, left turn indicator, right turn indicator, brake controller, taillights, power supply for battery, and stop lights. The wiring for the 7-pin socket can be according to the ISO standards (such as ISO 7638-2, ISO 1724, and ISO 3732, etc.), may be an SAE J560, and the like. The 13-pin socket includes 7-pins for the 7-pin socket and the remaining 6 pins are used for transfer of data from the cameras to the cabin of the vehicle, and may additionally be used for powering the cameras attached to the trailer as well.

[0019] In FIGS 1 and 2, there are two additional cables (i.e., pig tails) extending from the plug to connect the cameras to pins of the 13-pin socket; the two additional cables are connected to the remaining 6 pins in the 13-pin socket. In one embodiment, the cables include a GX12-4 connector at one end of the cable and the other end of the cables are attached to the plug. Each GX12-4 connector includes four pins, one for audio, one for video, one for ground, and one for power supply. The two additional cables in FIGS. 1 and 2 are shown for exemplary purposes, there can one or more than one additional cable based on the number of cameras installed onthe trailer. The remaining six pins (i.e., other than the reserved 7 pins for controlling the trailer) on the 13-pin socket can be used for multiple camera configurations. In a first configuration there can be one pin for power supply to the cameras, one pin for ground, and four pins for four channels of video from four cameras attached to the trailer. In a second configuration, each camera has its own set of pins: one for ground, one for power supply, and one pin for video transfer, with this arrangement duplicated for the two cameras.

[0020] The cabin of the vehicle can include a monitor to display the videos captured by the cameras attached to the trailer and / or recording media for storage of videos, and / or cellular communication means to transmit portions of the received video data to a remote cloud server. The data transfer pins in the 13-pin socket may be connected directly to the monitor via the 13- pin socket on the cabin of the vehicle or indirectly through a video storage and / or processing unit in the cabin.

[0021] In another embodiment, the wiring configuration for 13-pin socket may include 7 pins for trailer, and 6 pins for 6 channels of video from six cameras attached to the trailer. The power supply and ground for the cameras can be shared with the power supply and ground in the 7 pins of the trailer. In any of the above configurations, an audio pin in a 4-pin connector of the camera may not be connected to the 13-pin socket.

[0022] In one embodiment, the audio and video channels from the cameras can be connected to the 13-pin socket. In this case, the power supply and ground for the cameras may be shared from power supply and ground in the standard 7-pins pathway utilized for controlling the trailer. When both audio and video channels are connected to the 13-pin socket, a maximum of three cameras can be connected to the 13-pin socket.

[0023] In various embodiments, the 13-pin socket attached to the vehicle can be male type and the 13-pin socket attached to the adapter can be female type, or vice versa. In various embodiments, the 7-pin socket attached to the trailer can be male type and 7-pin socket attached to the housing of the adapter can be female type, or vice versa.

[0024] In some embodiments, the housing includes two arms extending from the cylindrical structure. The two arms may be used for mechanically coupling the adapter to the trailer. Each of two arms include a hole for allowing the fixing means (i.e., bolts) to couple the adapter to the trailer.

[0025] In one embodiment, the adapter can have a pin configuration different from 7-pin at one end and 13-pin at another end. The adapter can be 5-pin at one end and 13-pin at anotherend. The adapter can have first set of pins at one end and second set of pins at another end, where the first set can be lower than the second set, or vice versa.

[0026] The various embodiments described above each provide one or more of the following advantages relative to existing systems and methods for capturing and communicating video data from a trailer to a truck cabin (or device therein). Providing a wired solution avoids pairing issues, connectivity issues, or video quality loss as seen with wireless solutions. Relative to existing wired solutions, easier installation of a trailer video feed may result from the utilization of an existing mounting location and hardware associated with a standard truck / trailer connector. For example, no fabrication or custom mounting solutions are required such as would be for an additional dedicated 7-way signal path to support the video feed(s). Eliminating the need for a secondary cable reduces the risk of human error, as the required trailer connections and video are in a shared connection, providing a single connection point for the driver.Installation and configuration considerations

[0027] The installation process of the adapter may involve firmly attaching two adapters, each into an existing 7-way connector on both the truck and the trailer, respectively. The adapter may be designed to use existing mounting holes that may be associated with the 7-way connector. Referring to FIG. 3 A, longer bolts may used to secure the adapter in place, such as through a hole (310) in a wing (308) of the housing (102). The large bolt may go through the hole (310) and then through a corresponding hole of an existing 7-way connector on the truck (or trailer). Given that trucks may pair with different trailers on different days, firm attachment will help the adapter system withstand the rigors of regular use. Likewise, the adapter's housing is constructed from durable materials, such as metal or high-strength plastic, to protect the internal circuitry from environmental factors, such as moisture, dust, and vibrations. This rugged design ensures reliable operation in various conditions encountered during vehicle operation.

[0028] Once installed, referring to FIG. 2, the adapter allows for a single 13 -pin cable (210) to be connected between the truck and the trailer. This single connection may carry all the necessary signals for trailer operation, including lighting, brakes, and additional video signals from one or more cameras mounted on the trailer. This single cable solution simplifies the connection process for the driver, reducing the likelihood of connection errors.

[0029] The adapter includes internal wiring that connects the 7-pin signals from the trailer to the corresponding pins in the 13 -pin socket. Additionally, in an embodiment, the adapter provides connections for up to two cameras, with dedicated pins for video signals, power, and ground. This configuration ensures that video signals from the cameras are reliably transmitted to the cabin of the vehicle.

[0030] The cameras connected to the adapter can be configured to provide various views, such as rear-view, side-view, or top-view, depending on the placement of the cameras on the trailer. These video may can be displayed on a monitor in the cabin, providing the driver with enhanced visibility and situational awareness.

[0031] In one embodiment, the adapter includes a built-in power regulation module to ensure that the cameras receive a stable power supply, regardless of fluctuations in the vehicle's electrical system. This helps to prevent video signal loss or degradation due to power issues.

[0032] The adapter may be designed to be compatible with industry-standard AV connectors, such as GX12-4 connectors, making it easy to integrate with existing camera systems. This compatibility allows for flexibility in camera selection and ensures that the adapter can work with a wide range of commercially available cameras. Referring to FIG. 2, in some embodiments, there may be two versions of the adapter. Each version may be substantially identical except that the gender of the camera pathway connection may be different, reflecting the standard signal pathway which may be directional. For example, there may be a female connector on the camera cables (114) on the trailer adapter and a male connector on the truck adapter camera cables, so that they can receive male or female GX12-4 connectors, respectively.

[0033] In addition to video signals, in some embodiments, the adapter may be configured to support audio signals from cameras equipped with microphones. This configuration enables the capture and transmission of audio data, which can be useful for monitoring trailer conditions communicating with personnel near the trailer.

[0034] The adapter may also include diagnostic features, such as LED indicators, to provide visual feedback on the status of the connections and the health of the system. This can help the driver quickly identify and troubleshoot any issues with the trailer's electrical connections.

[0035] Overall, the adapter provides a comprehensive solution for integrating video, power, and other data signals between a truck and a trailer. By consolidating these signals into a single connection, the adapter simplifies the connection process, enhances reliability, and improves the overall safety and functionality of the vehicle-trailer system.

[0036] In Europe, where 13 -pin sockets are commonly used by default for trailer connections, the adapter can still offer benefits by enhancing the functionality and ease of integration for video and data signals. The European 13-pin standard typically includes connections for all necessary trailer functions such as lighting, brakes, and auxiliary power, with some connections left unused. This may be common as European trucks and trailers are required to remain interoperable across multiple countries. However, the standard 13-pin sockets may not provide dedicated channels for additional video feeds from multiple cameras. The adapter as disclosed here can be configured to utilize the existing 13-pin infrastructure while adding the capability to handle multiple camera inputs. This may be achieved, for example, by configuring a 13-pin to 13-pin adapter, wherein connections to some of the pins are wired to one or more camera cables, such as camera cables (114) illustrated in FIG. 1. These camera signal pathways would typically correspond to unused signal paths (or signal paths that are available for repurposing) on the existing 13-pin connectors of the truck and trailer. This allows for seamless integration of advanced camera systems without the need for additional wiring or modifications to the existing 13-pin connector, providing a straightforward and reliable solution for enhancing driver visibility and safety.

[0037] The 13-pin to “13-pin plus camera path” version of the adapter may comply with European automotive standards, ensuring compatibility with the existing 13-pin systems used across the continent. By leveraging the unused or auxiliary pins within the standard 13-pin configuration, the adapter can transmit video signals from multiple cameras directly to the vehicle's cabin. This approach maintains the integrity of the standard connections while expanding the functionality to support advanced safety features.

[0038] Referring to FIG. 4, the present disclosure provides a system for recording video from trailer-mounted cameras within the vehicle, which may also be applied to cameras that are mounted within the vehicle. The video from a trailer-mounted camera (402) may be transmitted to an analog high-definition video decoder, which may be integrated into a digital video recorder (DVR), a tablet docking station, or the like, which may be installed in the vehicle. A DVR configured with multiple analog and / or digital camera inputs may be referred to as D-HUB or Driver.i HubX®. In some embodiments, a D-HUB (404) may record the video. FIG. 4 further illustrates how such video data may be integrated with other vehicle signals that may be reach via a CAN interface (406) and may be transmitted to a cloud-based intelligent driver monitoring system.Multifunctional video display tablet in the vehicle cabin

[0039] In accordance with another embodiment, the present disclosure provides a system for displaying video from trailer-mounted cameras on a tablet within the vehicle. Likewise, if the analog high-definition video decoder is integrated within the DVR, the DVR may forward one or more video feeds to the tablet. This arrangement allows for the integration of one or more video feeds from the cameras mounted on the trailer, ensuring that the driver has access to visual information, but without adding additional video displays in addition to what is already being used for fleet management purposes. Examples of fleet management purposes that may be advantageously integrated within the same multifunction tablet may include an electronic logging device (ELD) which may have an interactive display, and / or other functions, such as vehicle inspection functionality. Further examples of driver safety and fleet management or fleet compliance functionality are discussed below.

[0040] The system includes a tablet that can be mounted to the vehicle using a docking station. The docking station may be configured to receive camera inputs in multiple ways. Referring to FIG. 5, the docking station (502) can process analog camera signals internally for display on the tablet. Referring to FIG. 6, the docking station (602) can receive digitized video signals from the analog high-definition video decoder, which may be referred to as a DVR or DHUB (604). The digitized signal may be transmitted wirelessly, such as through WiFi (606), or through a wired connection, providing flexibility in how the system is configured within the vehicle cabin. The system simplifies installation and maintenance by leveraging existing mounting points and power connections in the vehicle. The docking station may be installed using standard hardware, reducing installation time and costs.

[0041] Certain aspects address latency and connectivity issues that may be associated with wireless solutions for video transmission. Wireless solutions may suffer from long latencies, affecting the real-time utility of safety monitoring. By providing the option to transmit digitized video signals through a wired connection when the tablet is docked, the system ensures that the video feed is timely and reliable.

[0042] In certain embodiments, the system may be capable of switching between wired or wireless camera feeds based on whether the tablet is docked. This flexibility addresses the need for reliable and adaptable connectivity options in certain situations, such as when it may be beneficial to view the camera feed from a location other than the driver’s seat.

[0043] Automatically switching from a wired to a wireless feed upon undocking the tablet may provide a useful, although lower latency view of relevant camera feeds that may support certainfleet management / compliance functions for which low latency and high resolution may be more acceptable. In some embodiments, the tablet may be undocked and used for various tasks such as ELD compliance, driver vehicle inspection reports, and other fleet management applications. For instance, after parking the vehicle, the driver can undock the tablet and carry it around to perform a vehicle inspection, recording any defects or issues directly into the fleet management system. This eliminates the need for paper-based reports and enhances the efficiency of the inspection process.

[0044] The tablet may automatically switch from a wireless to a wired feed upon docking the tablet in the docking station. In certain embodiments, video that is displayed on the tablet from a wired video feed may be higher resolution and / or displayed at a lower latency relative to video that is displayed on the same tablet but from a wireless feed. A better picture quality when docked may be considered a type of feedback that encourages a driver to take care that the tablet is properly docked before starting to drive.

[0045] Another issue with existing systems that is addressed concerns the use of fixed monitors, which cannot be easily moved or repurposed for other tasks. Fixed monitors are limited in their functionality and do not provide the flexibility required for modern fleet management. The disclosed system solves this problem by allowing the tablet to be easily undocked and used for various tasks, thereby enhancing its utility. Additionally, the docking station's ability to switch between wireless and wired connections based on the tablet's status (docked or undocked) provides a seamless user experience. When the tablet is docked, it uses a wired connection for stable and low-latency video transmission. When undocked, it switches to a wireless connection, maintaining functionality while offering mobility.

[0046] By serving as both a monitor and a fleet management device, the tablet eliminates the need for multiple screens and devices within the vehicle. This consolidation not only reduces clutter in the cab but also simplifies the driver's workflow, as all necessary information and controls may be accessible from a single device. One of the problems addressed by this system, therefore, is the redundancy and inconvenience associated with using multiple devices in the vehicle for different functions. Traditional setups typically involve separate devices for monitoring video feeds and managing fleet operations, which can lead to redundancy and increased complexity for the driver. By utilizing a single tablet for fleet safety and fleet management / compliance functions, the system streamlines operations and reduces the number of devices needed within the vehicle.

[0047] The tablet may serve multiple purposes, including monitoring camera feeds, managing fleet operations, and providing safety alerts and warnings. For example, the tablet can display real-time video feeds from the cameras, show fleet management data such as Electronic Logging Device (ELD) information, and integrate with Advanced Driver Assistance Systems (ADAS) to provide safety alerts.

[0048] In addition to ELD compliance, the tablet can support other fleet management tasks, such as driver vehicle inspection reports (DVIR). The driver can use the tablet to conduct pretrip and post-trip inspections, recording any defects or issues directly into the fleet management system. This digital approach streamlines the inspection process and ensures that all necessary information is accurately recorded and easily accessible.

[0049] The mobility of the tablet is a key feature that sets this system apart from traditional solutions. The ability to undock the tablet and use it outside the vehicle provides significant advantages in terms of flexibility and convenience. For example, a driver can undock the tablet and use it to capture signatures for delivery confirmations, eliminating the need for separate devices or paper-based processes.

[0050] A detachable multifunctional tablet and video monitor may significantly improve fleet management. This integration allows fleet operators to streamline operations, reduce equipment costs, and improve overall efficiency. In some embodiments, The tablet features a customizable user interface that can be tailored to the specific needs of the fleet. Fleet operators can configure the interface to prioritize certain functions, such as ELD compliance, video inspections, and / or delivery confirmation functionality. Alternatively, or in addition , the system dynamically switches functions based on the context of use, such as whether the vehicle is in motion, stationary, or parked. For instance, when the vehicle is in motion, the tablet restricts access to certain features like vehicle inspection workflows to prevent driver distraction. Conversely, when the vehicle is stationary, the tablet enables all available features that a driver may utilize while stationary, such as video playback, inspection checklists, and ELD data entry.

[0051] Automatic workflows with undocking may be configured by a cloud server via a connected Al dashcam, such as a Driver.i dashcam. With the Al dashcam being connected to the cloud, many more workflows may be enabled through this cloud connection. For example, when entering a geofenced area of a customer site as defined in the cloud and detected by the device, when the tablet is undocked, the tablet interface may enter a custom form flow to collect a signature and take an image of a delivery. At a different geofence the side camera may helpto show a trash bin is aligning with the arm. These examples further illustrate the utility of an integrated ecosystem of safety and fleet management functionality, including functionality that may be enabled by remote configurations. According to certain embodiments, the automatic workflows that are triggered by vehicle motion, geolocation, recent history of fleet management variables, and the like, may be configured via a cloud server that interfaces with the tablet via the cellular connection of an Al dashcam system.

[0052] The system enhances driver safety by integrating with Advanced Driver Assistance Systems (ADAS) while the vehicle is in motion. The tablet can display alerts and warnings based on data from ADAS sensors, such as lane departure warnings, collision avoidance alerts, and pedestrian detection. These real-time alerts help drivers avoid potential hazards and improve overall safety.

[0053] Another example of the tablet's mobility is its use in vehicle inspections. A driver can undock the tablet and carry it around the vehicle, using it to document any issues or defects. The tablet can also display inspection checklists and guide the driver through the inspection process, ensuring that all necessary checks are completed.

[0054] The system also simplifies the installation process, which can be a significant challenge with existing wired solutions. Traditional systems often require complex installations with custom mounting solutions and additional signal pathways, increasing the risk of human error and extending installation time. By using a docking station that leverages existing mounting locations, hardware, and / or power connection, the system reduces installation complexity and minimizes the risk of errors.

[0055] For instance, consider a fleet operator who needs to equip a fleet of trucks with camera monitoring and fleet management capabilities. With the disclosed system, the operator can use the existing dashboard mounting points for the docking station, avoiding the need for additional custom mounts. This not only saves time but also reduces costs associated with installation.

[0056] Another technical solution provided by the system is the ability to integrate with existing fleet management software and hardware. The tablet can communicate with other systems and devices used by the fleet, such as GPS trackers, telematics devices, and dispatch software. This integration allows for seamless data sharing and coordination, enhancing overall operational efficiency.

[0057] The system's ability to process both analog and digitized signals further enhances its versatility. In some fleet operations, existing cameras may output analog signals. The docking station can process these signals internally and convert them for display on the tablet,eliminating the need for additional hardware or signal converters. This capability allows fleet operators to upgrade their monitoring systems without replacing existing camera infrastructure, providing a cost-effective solution.

[0058] The disclosed system enhances safety through its integration with ADAS. The tablet can display safety alerts and warnings based on data from the vehicle's sensors and cameras. For example, if the system detects a pedestrian in the vehicle's blind spot, it can trigger a visual alert on the tablet, helping the driver avoid potential collisions. The integration with ADAS also allows the system to provide lane departure warnings, collision avoidance alerts, and other safety features, directly to the driver. These alerts can help prevent accidents and improve overall safety for both the driver and other road users. The ability to provide real-time safety feedback is particularly valuable in fleet operations, where driver safety is a top priority. Fleet managers can use the data collected by the system to identify patterns in driver behavior, including unsafe lane changes. This information can be used to develop targeted training programs aimed at improving driver safety and efficiency. Additionally, the centralized data can be used to streamline maintenance schedules, reducing downtime and improving vehicle reliability.

[0059] Another example of the system's safety functionality is its ability to provide real-time feedback on driver behavior. If the system detects that the driver is engaging in unsafe practices, such as failing to stop at a stop sign or traffic light, it may display a warning and suggest corrective actions. This real-time feedback may help improve driver safety habits and enhance overall safety. In some embodiments, certain low-risk event detections may be presented soon after the detected event rather than before, so as to generally avoid a driver’s reliance on safety warnings and potentially faulty ADAS or semi-autonomous functionality, and instead promoting safe and proactive driving habits.

[0060] Some of these functions are available whether the vehicle is in motion or stationary, allowing for continuous monitoring and management, as well as safety applications. For example, video monitoring while stationary may serve as an additional layer of security or theft prevention. Other functions may be disabled while the vehicle is in motion, depending on the function. For example, vehicle inspection workflows may be irrelevant while the vehicle is in motion. The tablet may be configured so that displays related to vehicle inspection workflows may be automatically suppressed when the vehicle is in motion.

[0061] Illustratively, consider a scenario where a driver needs to monitor the rear view of the trailer while stopped and preparing to exit a vehicle. The tablet, mounted on the dashboard,displays the real-time video feed from the rear-mounted camera, helping the driver determine if a potential resting or parking location is safe. Simultaneously, the tablet may also display ELD information, such as the remaining hours of service, ensuring that the driver remains compliant with regulatory requirements, and / or may provide information about the availability of nearby parking.

[0062] The docking station can receive camera inputs in multiple ways, allowing for flexibility in how the system is configured. For instance, the docking station can process analog camera signals internally, converting them for display on the tablet. Alternatively, it can receive digitized video signals from the DHUB, which can be transmitted wirelessly or through a wired connection.

[0063] This flexibility in connectivity options is particularly beneficial in situations where wireless connectivity may be unreliable and / or insecure. For example, in areas with a high density of interfering wireless signals, the system can switch to a wired connection when the tablet is docked, ensuring that the video feed remains stable and reliable. Alternatively, the system may switch to a record-only mode.

[0064] The ability to switch between wireless and wired connections also enhances the system's usability. When the tablet is docked, it can utilize a wired connection for stable and low-latency video transmission, which is crucial for real-time monitoring and safety applications. When the tablet is undocked, it can seamlessly switch to a wireless connection, maintaining its functionality while providing the mobility required for tasks outside the vehicle.

[0065] The digitized video signals from the DVR can be transmitted to the docking station via wireless or wired connections. The wireless transmission option is particularly useful in situations where cabling may be impractical or cost prohibitive. For example, in a large fleet with tractors and trailers of varying configurations, establishing a wireless link between the DHUB and the docking station can simplify the setup and reduce installation time.

[0066] The system's ability to digitize, further process, and display video data in the vehicle may also enhance transparency and accountability within the fleet. Drivers can verify if and how privacy filtering of a camera is being implemented, for example. In certain configurations, a driver may be able to verify that portions of the interior of a truck cabin, such as an entry to a sleeper compartment are blurred or masked, in accordance with a desired privacy setting. This transparency helps build trust between drivers and management and fosters a culture of safety and accountability within the fleet.

[0067] The system further includes robust privacy and security features to protect sensitive data. The tablet and docking station use encryption protocols to secure data transmission, and authentication mechanisms to verify user identities. The system may be further configured with customizable privacy settings, allowing drivers to control the visibility of certain data, such as interior camera feeds.

[0068] The system supports cloud connectivity, allowing data to be synchronized between the tablet and central fleet management systems, but may do so by leveraging a cellular network connection from another device in the vehicle. Additionally, the system supports over-the-air updates, allowing software and firmware updates to be deployed remotely without the need for physical intervention or a dedicated cellular network connection on the tablet.

[0069] With the increasing reliance on digital systems for fleet management, data security is a critical concern. The tablet and docking station use secure communication protocols to transmit data, ensuring that sensitive information is protected from unauthorized access. Additionally, the system includes authentication mechanisms to verify the identity of users, further enhancing data security.
