Description

ADAPTABLE RIDER ASSISTING REAR VIEW MIRROR FOR TWO WHEELERSTECHNICAL FIELD

[0001] The present invention relates to, in general, the rider assistance system for two wheelers and more specifically, is designed to account for the effect of steering rotation during turn in two wheelers and provide more visibility of traffic coming from behind with the help of adaptive rear view mirrors.BACKGROUND OF THE INVENTION

[0002] Providing alerts to two wheeler riders in traffic is a challenge, as the riders wear a helmet, and operate in a noisy environment that is affected by wind, engine noise, etc. During turns on the road the rear mirrors of the two wheelers become less effective. When the handle turns, the mirrors stop showing the rear view to the rider. Rear view mirrors help in identifying what is coming from behind. They are also helpful in changing lanes, the person can just take a quick glance and change the lanes. Rear-view mirrors are an important road safety tool. While driving a vehicle, a driver must constantly review his surroundings to avoid a collision. Side rear-view mirrors assist a driver in reviewing the surroundings generally disposed behind the driver without the driver having to turn his head more than necessary.

[0003] Driving without a rear view mirror is very difficult during traffic or at sharp turns of roads. Besides providing better visibility, rear-view mirrors assist the rider to judge the traffic behind and change lanes, overtake or even slow down. Thus, rear view mirrors make roads safer for both the user as well as his surroundings.

[0004] Rear view mirrors on a two wheeler help the rider to see the road users behind him. This provides better judgment and enables them to steer clear of vehicles approaching at high speeds.

[0005] Furthermore, typically the position of the rear view mirror is adjusted by the rider such that the viewing angle for the individual is effective in showing the objects behind the vehicle. However, while a single position of the rear-view mirror may be effective while the vehicle is moving straight, it is much less effective during turns. For example, during a right turn, instead of showing vehicles that may be approaching the vehicle from the right side, the rear view mirror will show the objects behind but on the left of the vehicle. Since the chances of accidents are far higher because of vehicles coming from the same side as the turn, the effectiveness of rear-view mirrors is therefore compromised because of their fixed position with respect to the steering of the two- wheeler.SUMMARY OF THE INVENTION

[0006] The present invention discloses the rider assistance system for two wheelers and it is designed to undo the effect of steering rotation during turn in two wheelers and provide more visibility of traffic coming from behind with the help of adaptive rear view mirrors. This would allow a user to ride more comfortably without the need to constantly adjust the rear mirrors.

[0007] In one embodiment the system may include a. Rear view assembly 151 and Control Unit 152. Rear View assembly has two parts, 1. Sensor, 2. Actuator Motor. Here Sensoris a Steering angle sensor that can sense the position of the steering. Actuator Motors help in rotating the left and right rear view mirrors.

[0008] In this embodiment, the Control Unit is configured as a controlling mechanism for the movement or turning of the rear-view mirrors to the desired position. The desired position may be related to the steering angle sensor data output or a fixed movement of the rear-view mirror independent of the steering angle.

[0009] In one embodiment, the control unit may be configured to compensate for the exact steering angle, based on the output of the sensor, by counter-rotating the corresponding rear view mirror to the same degree as the steering. E.g. if the steering rotates by 15 degrees for a right turn (ie. clockwise from the top view), the control unit may turn the right side mirror in the opposite direction (ie. counterclockwise from the top view) by 15 degrees, and the left side mirror in the opposite direction (ie. counterclockwise from the top view) so that the angular position of the mirror with respect to the road remains unchanged, giving the rider the same view as before the steering was turned. A person skilled in the art may realize that rotating the right and the left mirror counterclockwise (ie. to the left) during the right turn implies turning right mirror outwards and rotating the left mirror inwards.

[0010] In one embodiment when the rider switches on the right indicator the mirrors rotate to a rotated position and when the rider switches off the right indicator the mirrors come back to the normal position. Similarly, when the rider switches on the left indicator the left mirror protrudes outward (i.e. clockwise from the top view) and when the rider switches off the left indicator the mirror comes back to the normal position. The rangeof rotation is predefined and does not depend on the steering Angle. In another variant, both mirrors can be rotated on both right as well as left turn to ensure better visibility on both rear-view mirrors. Alternatively, a switch separate from the right / left turn indicator may be provided to initiate movement of the mirrors

[0011] The important aspects of this invention are: (1) the present invention provides the rear-view mirror assembly having a means to account for the effect of steering rotation during turn in two wheelers and provide better visibility of traffic coming from behind;(2) The rear-view mirror assembly maybe configured for both the Right and Left Rear View Mirrors; (3)The Rear View assembly of the present invention has a very simple structure and it operates very quickly, precisely and effectively; (4)The rear-view mirror assembly of the present invention has a Actuator Motor which operates and rotate the rear view mirror very quickly; (5) Control Unit controls the adjustment of rear view mirrors based on the status of the turn indicators and / or a steering angle sensor..BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well as the singular forms, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0024] Unless, otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one having ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0025] In describing the invention, it will be understood that a number of techniques and steps are disclosed. Each of these has individual benefits and each can also be used in conjunction with one or more, or in some cases all, of the other disclosed techniques.Accordingly, for the sake of clarity, this description will refrain from repeating every possible combination of the individual steps in an unnecessary fashion.

[0026] The present invention relates to the rider assistance system for two wheelers and it is designed to account for the effect of steering rotation during turn in two wheelers and provide more visibility of traffic coming from behind with the help of adaptive rear view mirrors.

[0027] This invention also aims to solve the limitations for two wheelers and provide solutions for better visibility, and assist the rider to judge the traffic behind and change lanes, overtake or even slow down.

[0028] An embodiment of the present invention consists of a. Rear View Assembly, and the b. control Unit, the rear view mirror / s. One may be a Sensor and the other part is Actuator Motor. Sensor maybe a steering angle sensor that is configured to sense the position of the steering, and a mirror angle sensor configured to sense the angle of the mirror. Steering angle sensor may be mounted inside the steering column in order to detect the steering’s absolute angle with respect to the vehicle’s frame. The mirror angle sensor / s may be each attached to respective mirrors. Actuator Motors actuate the rotation of the left and right rear view mirrors. There may be one or more actuator motors. Actuator motors are mounted over the Steering and connected to the handle of the rear view mirrors. In one exemplary embodiment, the left actuator motor may be placed in between the handle of the Left rear view Mirror and steering, Similarly, in one exemplary embodiment, the right actuator motor may be placed between the handle of the Right rear view mirror and steering. Alternate positions for the mirrors, as long asthey face generally backwards allowing viewing of traffic behind the rider may be allowed. In an embodiment, the mirror may be placed further outside as compared to the handle and a user grip on the handle. In one embodiment, the rotation of the mirror may be shown to the user on an interface / visual screen.

[0029] The Control Unit works as a controlling mechanism and can be mounted anywhere on the vehicle, control unit may read the position of the Steering angle sensor, as well as the mirror angle sensor / s. The control unit may also be configured to actuate the appropriate motor to keep the mirrors in the desired position. One control unit may control the position of both the rear view mirrors. The control unit may be configured to signal the actuator motor for rotation of said rear view mirror depending upon receiving a turn indicative signal. The turn indicative signal may be of various kinds. For example, switching ON of a vehicular turn indicator may be a turn indicative signal or lead to creation of a turn indicative signal. Further, the rotation of the steering angle, or change of steering angle may be a turn indicative signal or lead to creation of a turn indicative signal.

[0030] In another embodiment, the Adaptive rear-view mirrors rotate with steering to account for the effect of steering rotation during turn on the road. When the rider switches on the button for the right indicator, the right rear view mirror and / or left rear view mirror rotates and go to the set predefined angle upon rotation and when the rider switches off the button of the right indicator the rear view mirror / s come back to the normal positions. Similarly, when the rider switches on the button of the left indicator the left rear view mirror / s protrude outward and when the rider switches off the button of the left indicator the mirror / s come back to the normal position. In one scenario, thepredefined angle and corresponding predefined range of rotation for the mirror / s may not depend upon the steering angle. In other words, the mirror angle sensor may be configured to sense a mirror angle with respect to the steering. Further, the control unit may be configured to signal the actuator motor for rotation of said rear view mirror upon receiving a turn indicative signal and the current status of the mirror angle.

[0031] In another embodiment, the action of the adaptive mirrors rotating against the direction of the steering may happen automatically. le. when viewed from the top the clockwise motion of the steering may cause initiation of anticlockwise rotation of the mirror. In this embodiment, the angle to which the mirrors may rotate may not be predefined. Also, the actuation of rotation may not be triggered by a turn switch / separate switch. Rather, the trigger for rotation of the mirrors may be the steering rotation itself. In another variation of the above theme, the feature of auto rotation of the mirrors may be activated or deactivated based on an ON / OFF switch. When the control unit is configured to turn the said atleast one rear view mirror as a function of the change of steering angle that function may be of various kinds. For example, there might be an inverse proportion relation, wherein on 20 degrees clockwise turn of a steering wheel(right turn), 5 degree rotation of the mirror takes place in anticlockwise direction.

[0032] Figure la (Fig. la) illustrates an adaptable rear view mirror system in two wheelers, as per an embodiment herein. In one embodiment the rotation of the right mirror and the left mirror maybe controlled by the same motor. Also the degree of rotation maybe equal. Alternatively, two separate mirrors maybe used and the degree of rotation of each may differ. For example, a right side Actuator Motor 101 is mounted on the right side of the Steering, and a left side actuator Motor 102 is mounted on the left side of theSteering. Both the Actuator Motors 101 and 102 connect to the handle of the Right rear view mirror 103 and Left rear view mirror 104. Actuator motor 101 rotates the right rear view mirror 103. In a similar way, Actuator motor 102 rotates the left rear view mirror 104. There may be a steering rotation Sensor 105 which is mounted on the steering column. Sensor is also termed as Steering angle Sensor and it senses the position or turn status of the Steering.

[0033] In one embodiment, for extra safety a switch to activate and deactivate rotation of mirrors using steering sensor may be provided. Further, another switch allow activation or deactivation of rotation of mirrors using indicator switch may be provided.

[0034] Figure lb (Fig. lb) illustrates a block diagram of an adaptable rear view mirror system in two wheelers, as per an embodiment herein. A rear view assembly 151 may comprise of one or more sensor steering angle sensor 151a to detect the rotation of the steering. Further, one or more actuator motor 151b may be used to cause the mirror / s to rotate. Furthermore, a rear view mirror angle sensor 151c may be used to detect the current angle of the rear view mirror / s.

[0035] A person in the art may realize that gear systems may be present to affect the rotation of the mirror / s. While the rotation of the mirrors may be done in response to the steering handle rotation, the scenario where the rotation of the mirrors may be caused irrespective is also possible.

[0036] Figure 2 (Fig. 2) illustrates the top view of an exemplary scenario showing various subjects and angles at play as per an embodiment herein. More particularly, a two wheeler with / without adaptive mirror 201 trying to spot a viewing target 202 isexemplarily shown. The angle of incidence (i) 211 would be equal to the angle of reflection (r) 212.

[0037] Figure 3 (Fig. 3a and Fig. 3b collectively) illustrates the top view of an exemplary scenario when taking a right turn, showing the efficacy of the adaptive rear view mirror, providing riding assistance to the two wheelers, as per an embodiment herein.

[0038] More particularly, Figure 3a illustrates the top view of an exemplary scenario when taking a right turn without an adaptive mirror as per an embodiment herein. In the two exemplary scenarios of the rider 201 taking a right turn, as seen when these is no use of adaptive mirrors, the viewing target 202 may be missed by the rider 201, since the light incident from the target does not reach the rider after reflecting from the rear view mirror. Whereas in the scenario where the adaptive rear view mirror functions to rotate with the rotation of the steering handle of the vehicle, the viewing target would be visible clearly, almost similar to that when no turning was taking place as seen in figure 3b. In this latter scenario, the ray of light incident from the target after reflecting from the adaptive mirror reaches the rider.

[0039] Figure 4 (Fig. 4a and Fig. 4b collectively) illustrates the top view of an exemplary scenario when taking a left turn, showing the efficacy of the adaptive rear view mirror providing riding assistance to the two wheelers, as per an embodiment herein. In the two exemplary scenarios of the rider 201 taking a left turn, the first one that shows no use of adaptive mirrors, the viewing target 202 may be missed by the rider of 201. Whereas in the scenario where the adaptive rear view mirror functions to rotate with therotation of the steering handle of the vehicle, the viewing target would be visible clearly, almost similar to that when no turning was taking place.

[0040] Figure 5a illustrates the flowchart representation of an adaptable rear view mirror method in two wheelers as per an embodiment herein. Here switching ON of the indicator button 501 may be detected by a control unit. Indicator Button acts as to signal rotation of the adaptive mirrors to a predefined angle. Further, the Actuator Motor helps rear view mirrors to rotate 503. Later, on rider switching 504 off the indicator button the rear view mirrors come 505 to the normal Position. Alternatively, a switch separate from the right / left turn indicator may be provided to initiate movement of the mirrors.

[0041] Figure 5b illustrates the flowchart representation of an adaptable rear view mirror method in two wheelers as per an embodiment herein. These steps may represent the scenario when the steering angle sensor may be used to cause turning of the rear view mirror / s. The steps may comprise of: Steering angle Sensor sensing 502 the position or turn status of the Steering. This information may be conveyed to the control unit. Depending on the angle of steering rotation the control unit rotates 503 the left and the right mirror to the degree that allows a clear view of the traffic behind. This may be done by rotating each of the mirrors by the same degree or in proportion in a direction counter to that of steering rotation. Alternatively, each mirror may be rotated by different degrees depending on the type of turn and the position of the rider. Based on the indication from the control unit the Actuator Motor helps rear view mirrors to rotate for outward / inward view (i.e. rotate clockwise / anticlockwise).

[0042] An adaptable rear view mirror method in two wheelers as described above and illustrated in the figures may be performed (carried out), for example, in a system that includes a processor and a memory as may be embodied in, for example, a computing device which may communicate with a user input device and / or a user output device. In some embodiments, the system for acquiring spectral data from a sample (or an associated computing device) may be considered as including the user input device and / or the user output device. A control unit such as described above and illustrated may include, or be part of, or communicate with the central control unit of a two wheeler vehicle. As used herein, the term “perform” or “carry out” may encompass actions such as controlling and / or signal or data transmission. For example, a computing device or a processor thereof, may perform a method step by controlling another component involved in performing the method step. Performing or controlling may involve making calculations, or sending and / or receiving signals (e.g., control signals, instructions, measurement signals, parameter values, data, etc.).

[0043] As used herein, an “interface” or “user interface” is generally a system by which users interact with a computing device. An interface may include an input (e.g., a user input device) for allowing users to manipulate a computing device, and may include an output (e.g., a user output device) for allowing the system to present information and / or data, indicate the effects of the user's manipulation, etc. An example of an interface on a computing device includes a graphical user interface (GUI) that allows users to interact with programs in more ways than typing. A GUI typically may offer display objects, and visual indicators, as opposed to (or in addition to) text-based interfaces, typed command labels or text navigation to represent information and actions availableto a user. For example, an interface may be a display window or display object, which is selectable by a user of a computing device for interaction. The display object may be displayed on a display screen of a computing device and may be selected by and interacted with by a user using the interface. In one non-limiting example, the display of the computing device may be a touch screen, which may display the display icon. The user may depress the area of the touch screen at which the display icon is displayed for selecting the display icon. In another example, the user may use any other suitable interface of a computing device, such as a keypad, to select the display icon or display object. For example, the user may use a trackball or arrow keys for moving a cursor to highlight and select the display object.

[0044] It will be understood that one or more of the processes, sub-processes, and process steps described herein may be performed by hardware, firmware, software, or a combination of two or more of the foregoing, on one or more electronic or digitally-controlled devices. The software may reside in a software memory (not shown) in a suitable electronic processing component or system such as, for example, the control unit schematically depicted in Fig. la and Fig. lb. The software memory may include an ordered listing of executable instructions for implementing logical functions (that is, “logic” that may be implemented in digital form such as digital circuitry or source code, or in analog form such as an analog source such as an analog electrical, sound, or video signal). The instructions may be executed within a processing module, which includes, for example, one or more microprocessors, general purpose processors, combinations of processors, digital signal processors (DSPs), or application specific integrated circuits (ASICs). Further, the schematic diagramsdescribe a logical division of functions having physical (hardware and / or software) implementations that are not limited by architecture or the physical layout of the functions. The examples of systems described herein may be implemented in a variety of configurations and operate as hardware / software components in a single hardware / software unit, or in separate hardware / software units.

[0045] The executable instructions may be implemented as a computer program product having instructions stored therein which, when executed by a processing module of an electronic system (e.g., the control unit in FIGS, la and lb), direct the electronic system to carry out the instructions. The computer program product may be selectively embodied in any non-transitory computer-readable storage medium for use by or in connection with an instruction execution system, apparatus, or device, such as an electronic computer-based system, processor-containing system, or other system that may selectively fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. In the context of this disclosure, a computer-readable storage medium is any non-transitory means that may store the program for use by or in connection with the instruction execution system, apparatus, or device. The non-transitory computer-readable storage medium may selectively be, for example, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device. A non-exhaustive list of more specific examples of non-transitory computer readable media include: an electrical connection having one or more wires (electronic); a portable computer diskette (magnetic); a random access memory (electronic); a read-only memory (electronic); an erasable programmable read only memory such as, for example, flash memory (electronic); a compact disc memorysuch as, for example, CD-ROM, CD-R, CD-RW (optical); and digital versatile disc memory, i.e., DVD (optical). Note that the non-transitory computer- readable storage medium may even be paper or another suitable medium upon which the program is printed, as the program may be electronically captured via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner if necessary, and then stored in a computer memory or machine memory.

[0046] It will also be understood that the term “in signal communication” as used herein means that two or more systems, devices, components, modules, or sub-modules are capable of communicating with each other via signals that travel over some type of signal path. The signals may be communication, power, data, or energy signals, which may communicate information, power, or energy from a first system, device, component, module, or sub-module to a second system, device, component, module, or sub-module along a signal path between the first and second system, device, component, module, or sub-module. The signal paths may include physical, electrical, magnetic, electromagnetic, electrochemical, optical, wired, or wireless connections. The signal paths may also include additional systems, devices, components, modules, or sub-modules between the first and second system, device, component, module, or sub-module.

[0047] More generally, terms such as “communicate” and “in . . . communication with” (for example, a first component “communicates with” or “is in communication with” a second component) are used herein to indicate a structural, functional, mechanical, electrical, signal, optical, magnetic, electromagnetic, ionic or fluidic relationshipbetween two or more components or elements. As such, the fact that one component is said to communicate with a second component is not intended to exclude the possibility that additional components may be present between, and / or operatively associated or engaged with, the first and second components.

[0048] It will be understood that various aspects or details of the invention may be changed without departing from the scope of the invention. Furthermore, the foregoing description is for the purpose of illustration only, and not for the purpose of limitation — the invention being defined by the claims.
