Description

TECHNICAL FIELDThe present disclosure relates to the field of mirror assembly in a vehicle. In particular, the present disclosure provides a system and method for adjusting a flexible mirror assembly in the vehicle to adjust the field of view (FOV) for a user in the vehicle.BACKGROUNDA focus of research and development in the traffic area is autonomous driving and advanced driver assistance systems (ADAS). The rapid development in this area emphasizes the constant need for improvements and advances in enhancing vehicle safety, efficiency, and general driving experience. Vehicles are highly dependent on sensors and their visibility to make informed decisions based on environmental information and circumstances. In threshold countries, high traffic volume, insufficient road markings, taxes, and lack of localization techniques using high definition (HD) map data contribute to increased accident risk in safety critical lane change scenarios.The lack of flexible or pivotable mirrors is currently a challenge for the driver's vision. Lane merging scenarios require a large field of view (FOV) for accurate object detection because most lane transitions are wide-ranging and oncoming traffic needs to be detected. Existing problems include the insufficient handling of lane change scenarios and the limited use of the flexible mirrors.Many techniques have been developed to overcome the above problems. Thus, Patent Document KR100205538B1 describes a rearview mirror that is made up of a flat mirror with slight curvature on the left and right sides and enables observation of the rear environment. By installing the curved mirrors, the driver is provided with a view through the curved mirror ends of the 15° front angle, which corresponds to the front wheel of the vehicle. The left and right bent mirrors have a convex shape obtained by bending with a certain radius of curvature. The supporting structure of the mirror consists of a support fixed to the rear of the mirror and a suction plate connected via the support and the self-aligning shaft and forming the rear view mirror of the vehicle.Another patent document KR20180065665A describes a flexible side mirror controller for a vehicle that enables control of a flexible side mirror. This side mirror has independently curved opposite surfaces, both forward and rearward, which are related to a longitudinal center line of the mirror. Its purpose is to solve the blind spot problem when the vehicle is traveling backward and to allow the driver to observe obstacles detected by a blind spot detector (BSD) in lane change. The apparatus includes a left side flexible mirror having a front-rear curved left side surface; a right side flexible mirror having a front-rear curved right side surface; a direction indicator detecting unit for detecting the turning direction of the vehicle; a controller that selects a side flexible mirror corresponding to the detected turning direction and determines the appropriate angle of curvature for that selected mirror; and a mirror setting unit that is responsible for setting the selected side flexible mirror to curve by the determined angle.Another patent document US6076934A describes a mirror for the blind spot of a vehicle, which has a mirror with a surface curved outwards in a plane. To a rear part of an outwardly curved mirror is attached an extension member provided on an opposite surface of the extension member with a double-stick foam adhesive tape. With this construction, the extension and the blind spot mirror attached thereto can be attached to the existing rearview mirror of a vehicle even when the rearview mirror is inserted into a recessed frame. This allows a larger blind spot mirror compared to the original rearview mirror. In a preferred embodiment, the outwardly curved mirror is about seven and one-half inches wide and five inches high. It is radially curved so that the vertical central axis of the mirror is between thirty and eighty thousandths of an inch higher than the right or left edge. In an alternative embodiment, the outwardly curved mirror is mounted on the driver side instead of a conventional flat rearview mirror as is common in current motor vehicles.The conventional methods and systems have the disadvantage of requiring a transmission and an engine, which results in more complexity and is expensive. In addition, the conventional flexible mirror system depends on the movement of the steering wheel, which activates its function to reduce the blind spot, which can lead to potential restrictions in scenarios in which the steering movements are minimal or limited. In such cases, the responsiveness and effectiveness of the system in reducing the blind spot could be impaired. Another major drawback of the conventional methods is that they are manually operated and require human intervention for operation. Moreover, the conventional methods and systems do not have automatic operation based on situation analysis, indicating a potential design error.Therefore, there is a need to overcome at least the above-mentioned disadvantages and all other deficiencies or at least provide a valuable alternative to the existing mirror arrangement.OBJECT OF THE PRESENT DISCLOSUREA general object of the present disclosure is to provide an efficient and reliable mirror assembly in a vehicle that efficiently overcomes the above limitations of existing systems and methods.An object of the present disclosure is to provide a flexible mirror assembly that uses links and chains to reduce complexity and cost.Another object of the present disclosure is to provide a system and method for adjusting a flexible mirror assembly in a vehicle based on measuring the position of a host vehicle with respect to a lane transition angle.SUMMARYAspects of the present disclosure relate to the field of mirror assembly in a vehicle.

The embodiments are so detailed as to clearly convey the disclosure. However, it is not intended to limit the predictable variations of embodiments with the particularity provided; on the contrary, it is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.The embodiments discussed herein relate to the arrangement of mirrors in a vehicle. More particularly, the present disclosure relates to a system and method for adjusting a flexible mirror assembly in the vehicle to adjust a field of view (FOV) for a user in a vehicle. Various embodiments of the present disclosure will be explained in detail with reference to the FIGURES. 1-8.FIG. 1 shows a block diagram 100 of an example system 102 for adjusting a flexible mirror assembly 300B in a vehicle according to an embodiment of the present disclosure.As shown in FIG. 1, the system 102 may include one or more processors 104, a memory 106, and one or more interfaces 108. The one or more processors 104 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuits, and / or any devices that process data based on operating instructions. Among other capabilities, the one or more processor(s) 104 may be configured to fetch and execute computer readable instructions stored in the memory 106 of the system 102. The memory 106 may store one or more computer readable instructions or routines that may be fetched and executed to create or share the data units via a network service. The memory 106 may include any nonvolatile memory device, for example, volatile memory such as random access memory (RAM), or nonvolatile memory such as erasable programmable read-only memory (EPROM), flash memory, and the like.The interface(s) 108 may include a variety of interfaces, e.g., interfaces for data input and output devices referred to as I / O devices, storage devices, and the like. The interface(s) 108 may / may facilitate communication of the system 102 with various devices connected thereto. The interface(s) 108 may also provide a communication path for one or more components of the system 102. Examples of such components include processing engine(s) 110, sensor module(s) 112, and database 114. Database 114 may include data that is either stored or generated as a result of functions implemented by one of the components of processing machine(s) 110.In one embodiment, the processing machine(s) 110 may be implemented as a combination of hardware and programming (e.g., programmable instructions) to implement one or more functions of the processing machine(s) 110. In the examples described herein, such combinations of hardware and programming may be implemented in various ways. For example, the programming for the processing machine(s) 110 may consist of processor-executable instructions stored on a non-transitory machine-readable storage medium, and the hardware for the one or more processor(s) 104 may include a processing resource (e.g., one or more processors) to execute such instructions. In the present examples, the machine readable storage medium may store instructions that, when executed by the processing resource, implement the processing engine(s) 110. In such examples, the system 102 may include the machine readable storage medium storing the instructions and the processing resource for executing the instructions, or the machine readable storage medium may be separate but accessible to the system 102 and the processing resource. In other examples, the processing engine(s) 110 may be implemented by an electronic circuit. The processing engine(s) 110 may include an intended lane change determination module 116, a lane merging determination module 118, a distance determination module 120, a control signal generation module 122, and one or more other modules 124.In a scenario where a source vehicle is travelling on its planned path and is about to cross a roadway, a target vehicle is approaching the same roadway. During the intersection, the mirror of the source vehicle is automatically adjusted to improve vision. This adjustment makes it possible to better see the approaching vehicle, which ensures more reliable driving during the lane change. This function is designed so that blind spots are managed proactively, which increases the general safety in road traffic. In example embodiments, the vehicle may be a two-wheeler, a three-wheeler, a four-wheeler, a bus, a car, a truck, a transporter, or the like.The one or more processors 104 may receive route data along a route of the source vehicle, where the route data may include, but is not limited to, geographical coordinates, navigation instructions, road conditions, traffic updates, road profiles, road curvatures, and the like. As the source vehicle travels along the route, the intended lane change determination module 116 may determine an intended lane change of the source vehicle. Once the intended lane change is determined, the lane transition angle determination module 118 may determine a lane transition angle from the route data to determine whether or not the lane transition angle exceeds a predefined range. If the lane transition angle exceeds the predefined range, the module 120 may determine the motion of the host vehicle and a range of distances between the target vehicle and the host vehicle using the sensor module / s 112. The sensor module(s) 112 may include, but are not limited to, accelerometers, gyroscope sensors, infrared sensors, ultrasonic sensors, image sensors / cameras, lidar sensors, radar sensors, and the like. Once the module 120 has determined a range of distances between the target vehicle and the source vehicle, the module 122 may generate a control signal based on the determination that the lane transition angle exceeds the predefined range and the target vehicle is in the range of distances from the source vehicle. The one or more processors 104 may send the control signal to the flexible mirror assembly 300B to adjust the field of view (FOV) of the source vehicle to the vision of the user. The other(s) module(s) 124 may implement functionality(s) that supplement the applications / functions performed by the processing engine(s) 110.In some embodiments, the sensor modules 112 may detect the proximity of external objects such as obstacles, pedestrians, cyclists, traffic signs, traffic lights, or other objects or elements outside the host vehicle that may be detected during operation on the route.FIG. 2 shows a flow diagram of an example method 200 for preventing collisions in merging lanes according to an embodiment of the present disclosure.Referring to FIG. 2, at block 202, the method 200 may include detecting and analyzing road profiles and curvatures along a particular route using sensor modules (i.e., 112) in a vehicle. The sensor module(s) 112 may collect data including topography, elevation changes, various curves, and bends along a route, allowing a system (i.e., 102) to adapt and navigate accordingly. At block 204, the method 200 may include activating the vehicle to proactively prepare and perform lane change actions by evaluating road conditions, such as understanding the upcoming turns, detecting potential change points, and the like. At block 206, the method 200 may include detecting scenarios for merging lanes to determine suitable angles for merging roads using route data. By using a specific route, the vehicle can recognize specific points at which lane intersections are likely to occur along the route. At block 208, the method 200 may include folding over a flexible mirror assembly 300B to improve vision to both the driver and the passengers. This adaptive arrangement 300B may be configured to take into account different road profiles, curves, and environmental factors detected along the route, thereby ensuring an optimized field of view (FOV) for the driver and / or passengers in the vehicle.At block 210, the method 200 may include detecting oncoming traffic based on input received from the sensor module(s) 112. The sensor module(s) 112 may detect objects in the environment of the vehicle while the sensor module(s) 112 analyzes (analyze) this data to detect and classify various objects, e.g., other vehicles, pedestrians, or potential obstacles approaching the road from the opposite direction. The driver and passengers may increase their perception of target vehicles by utilizing the extended field of view that the flexible mirror assembly 300B provides. At block 212, the method 200 may include preventing collisions of the host vehicle with the target vehicles during the lane change by alerting the drivers and passengers to the target vehicles by expanding the field of view. At block 214, the method 200 may include activating a brake in the vehicle to prevent collisions with the oncoming vehicle.FIG. 3A shows an example illustration 300A of a normal position flexible mirror assembly 300B, in accordance with an embodiment of the present disclosure.Referring to FIG. 3A, the flexible mirror assembly 300B may include a first holder 302A, a second holder 302B, a flexible base 306, a support structure 308, a reflective sheet 310, a first connector 312A, and a second connector 312B. The first holder 302A and the second holder 302B may have inner and outer parts. The inner portion may include a groove and the outer portion may include a first connector 304A in the first holder 302A and a second connector 304B in the second holder 302B. The outer portion of the first retainer 302A and the second retainer 302B may include a first surface and a second surface, wherein the first surface and the second surface may include a hole. In the first holder 302A, the hole of the first surface may receive one end of the first connection member 304A and the second surface of the hole may receive another end of the first connection member 304A, also in the second holder 302B, the first surface of the hole may receive one end of the second connection member 304B, and the hole of the second surface may receive another end of the second connection member 304B.A support structure 308 may be attached to one side of the flexible base 306 via a fastener, the support structure being attached to a central portion of the one side of the flexible base. The fasteners may include, but are not limited to, screws, bolts, clips, clamps, adhesive materials, or other fastening mechanisms, for example. The reflective film 310 may be disposed on another side of the flexible base 306. The first end of the reflective sheet 310 and the flexible base 306 may fit into the groove of the first holder 302A, as well as the second end of the reflective sheet 310 and the flexible base 306 may fit into the groove of the second holder 302B.The first link 312A may be locked to the first link 304A and the second link 312B may be locked to the second link 304B. For example, the first connector 312A and the second connector 312B may include a first portion and a second portion, where the first portion of the first connector 312A may be locked to the first connector 304A, as well as the first portion of the second connector 312B may be locked to the second connector 304B. The second portion of the first connecting member 312A may be connected to a connecting tool 314, as well as the second portion of the second connecting member 312B may be connected to the connecting tool 314.FIG. 3B shows an example illustration of a flexible mirror assembly 300B in a flexible position according to an embodiment of the present disclosure.Referring to FIG. 3B, when the second portion of the first link 312A and the second link 312B is pulled in a rearward direction, a support structure 308 may restrict movement of a center of a flexible base 306, resulting in a first end and a second end of a reflective sheet 310 and the flexible base 306 being bent in parallel to form the bendable structure.FIG. 3C shows an example illustration 300C of a field of view (FOV) 316A when a flexible mirror assembly 300B is in a normal position, in accordance with an embodiment of the present disclosure. Referring to FIG. 3C, for example, when a vehicle is traveling in a straight line, the flexible mirror assembly 300B is normally positioned and the FOV 316A may restrict the user's vision.FIG. 3D shows an example illustration 300D of a field of view (FOV) 316B when a flexible mirror assembly 300B is in a bendable position, in accordance with an embodiment of the present disclosure. Referring to FIG. 3D, the field of view 316B may be increased when the flexible mirror assembly 300B is in the bendable position to improve visibility to users.FIG. 4 shows an example illustration 400 of estimation of a field of view (FOV) of a vehicle 402A, in accordance with an embodiment of the present disclosure.Referring to FIG. 4, the sensors, i.e., 112, may sense the environment of the external traffic, i.e., external objects around the vehicle 402A, and assign coordinates relative to a position of the vehicle 402A. For example, if the vehicle 402A is at (0,0,0), then the external traffic is at (x,y,z) with respect to the vehicle 402A. The sensors may measure a longitudinal distance between the vehicle 402A and portions of the external objects. For example, the longitudinal distance from the vehicle 402A to a front bumper of a target vehicle and a rear bumper of the target vehicle is measured. Additionally, the sensors may measure a lateral distance between a centerline of the vehicle 402A and the centerline of the target vehicle. Using the distance measurement, the sensors can measure viewing angles based on certain methods such as tan(Ø)=a / b, tan(μ)=c / b, α=μ- where Ø is the minimum angle required to view the target vehicle front bumper, μ is the maximum angle required to view the target vehicle rear bumper, and α is an opening angle required to view the target vehicle. Therefore, the upper limit of the FOV needs to be less than Ø and the FOV lower limit needs to be greater than μ to fully detect the target vehicle. The centerline of α is determined based on what corresponds to the direction of the target vehicle with respect to the vehicle 402A. Once α is measured, the radius of curvature R is also calculated using the formula R=L / α, assuming that the mirror is part of a circle having the radius R.Referring to FIG. 4, as the vehicle 402A travels along a route, the FOV is determined based on the determination of the angles Ø and μ, which represent the minimum ( ) and maximum (μ) limits of visibility, respectively. The full coverage condition requires Ø to exceed the upper limit of the FOV (Condition 1) and at the same time ensure that Ø remains below the lower limit of the FOV (Condition 2). Optionally, μ should be lower than the lower limit of the FOV. These conditions are determined based on the tangents of Ø (a / b) and Ø (c / b), where α is the difference between Ø and Ø. Initially, the joint angle (α) increases until Ø exceeds the upper threshold of the FOV and continues until μ falls below the lower limit of the FOV. Both Ø and μ are dynamically recomputed at each time stamp, so that the FOV angle continuously adjusts and compliance with specified conditions 1 and 2 is ensured. This adjustment ensures that the FOV always matches the required detection limits in response to changing circumstances.FIG. 5 shows an example plot 500 of measuring an impact angle between a target vehicle and a host vehicle, according to an embodiment of the present disclosure.In determining the angle of impact between the host vehicle 502 and the target vehicle 504, vector measurement plays a central role. In this measurement, the impact angle is determined based on the vectors associated with the relative speeds of the objects with respect to the host vehicle 502. As shown in FIG. 5, the bending angle, referred to as ∅ can be accurately measured. This angle represents the direction of impact and is derived from the vectors of the relative speeds, thereby depicting the relationship and angle at which the host vehicle 502 impacts the target vehicle in the context of the perspective of the host vehicle.FIGS. 6A-6B show example radius of curvature measurement plots 600A and 600B for a flexible mirror assembly 300B, according to an embodiment of the present disclosure.Referring to FIGS. 6A-6B, determining the radius of curvature for the flexible mirror assembly 300B involves determining the required radius R to achieve a particular field of view (FOV) represented by the angle Ø with a mirror of the defined length L. The relationship between the length of the mirror (L) and the radius (R) can be expressed by the equation L=R*α, enabling the measurement of R as R=L / α. This approach provides a practical method of calculating the required radius of curvature for the flexible mirror assembly 300B that ensures the desired field of view (FOV) based on the length of the mirror and the associated angle, which is critical for optimal optical performance.FIG. 7 shows a flow diagram of an example method 700 for folding and deploying a flexible mirror assembly 300B, according to an embodiment of the present disclosure.At block 702, the method 700 may include determining that a source vehicle enters a lane transition scenario. At block 704, the method 700 may include measuring a lane transition angle from map data and a motion of the host vehicle. At block 706, method 700 may include determining whether or not the lane transition angle exceeds a predefined range (i.e., 15>trace transition angle>65). For example, if the toe transition angle exceeds the predefined range, method 700 may include determining an approaching vehicle in the vicinity, as well as continuing to measure the toe transition angle if the toe transition angle does not exceed the predefined range. At block 710, the method 700 may include folding the mirrors while merging into the lane to facilitate the driver. At block 712, the method 700 may include continuing normal operation once the host vehicle has performed the lane change. At block 714, the method 700 may include folding out the mirrors for a Field of View (FOV).FIG. 8 shows a flow diagram of an example method 800 for adjusting a flexible mirror assembly 300B in a vehicle according to an embodiment of the present disclosure.At block 802, the method 800 may include receiving route data along a route of the vehicle. At block 804, the method 800 may include determining an intended lane change of the vehicle based on the route data. At block 806, the method 800 may include determining a lane transition angle from the route data. At block 808, the method 800 may include determining that the lane transition angle exceeds a predefined range. At block 810, the method 800 may include determining a range of distances between one or more external objects and the vehicle using one or more sensors connected to the system based on the determination. At block 812, the method 800 may include generating a control signal when the lane transition angle exceeds the predefined range and the one or more external objects are in the area proximate the vehicle. At block 814, the method 800 may include sending, by the one or more processors, the control signal to a flexible mirror assembly to adjust the field of view for the user in the vehicle.While the foregoing describes various embodiments of the disclosure, other and further embodiments of the invention may be devised without departing from the basic scope of the disclosure.
