Description:FIELD OF THE INVENTION
[001] Present invention relates to a system and a method for providing riding assistance to a rider of a vehicle. More specifically, the present invention relates to a system and a method for providing riding assistance to the rider during a reverse riding mode of the vehicle.

BACKGROUND OF THE INVENTION
[002] In two-wheeled vehicles, a rider is benefited when riding assistance is provided by the vehicle. The rider can comprehend the status of various components of the vehicle as well as the surrounding environment. Typically, the rider is skilled in driving the vehicle in a forward direction only and the riding assistance further aids the rider in driving the vehicle. However, riding the vehicle in a reverse direction is a challenge for the rider, as reverse riding requires the rider to turn his head or body backwards for observing the surroundings while simultaneously balancing the vehicle. In doing so, a posture of the rider becomes non-ergonomic and prolonged repetitions of non-ergonomic postures may provide discomfort to the rider which is undesirable.
[003] To overcome the above-mentioned issues, conventional vehicles provide the riding assistance that includes a rear-mounted camera and a screen, to display a rear view of the vehicle on the screen to the rider. The screen also depicts straight lines along with the rear view captured by the rear-mounted camera to the rider. The straight lines on the screen depicts a travel path for the vehicle during the reverse riding for the rider’s consideration, thereby assisting the rider during reverse riding of the vehicle. However, the straight lines do not portray left and right reverse turning and leaning of the vehicle. As a result, the rider is again required to turn backwards for the reverse riding which is undesirable. Moreover, straight lines may not be sufficient to depict the travel path of the vehicle during reverse riding, as the travel path depicted through the straight lines does not consider the leaning of the vehicle.
[004] Thus, there is a need for a system and a method for providing riding assistance to the rider during a reverse riding mode of the vehicle, which addresses at least one or more aforementioned problems.

[032] The depth estimation unit 116 comprises a neural network unit 120. The neural network unit 120 is communicatively coupled to the image sensor 104 and the image processing unit 118 and configured to receive the image data and the determined one or more obstacles. The control unit 102 is adapted to estimate a distance between a rear portion of the vehicle 126 and the determined one or more obstacles using a depth estimation model. The term, “rear portion” of the vehicle 126 refers to one of the tail lamp, the number plate, a rear wheel, and the like. The depth estimation model is executed by the depth estimation unit 116 using the neural network unit 120. Further, the control unit 102 is adapted to alert the rider of the vehicle 126 when the distance between the rear portion of the vehicle 126 and the one or more obstacles is below a threshold value. In one embodiment, the threshold value is 100 cm. In an embodiment, the image processing unit 118 and/or the neural network unit 120 may be data driven models such as trained neural networks, generic algorithms and now known or later developed algorithms.
[033] The system 100 comprises one or more alerting devices 110. The one or more alerting devices 110 include at least one of the display device 124 or blinking LEDs (not shown), an audible device 128, and a haptic device 130 located on at least one of a rider seat, a handlebar, and a foot peddle, and the like. The one or more alerting devices 110 are configured to alert the rider through one of a visual alert, an audible alert, and a haptic alert via the instrument cluster 108 or the blinking LEDs, the audible device 128, and the haptic device 130, respectively. The one or more alerting devices 110 are configured to alert the rider when the distance between the rear portion of the vehicle 126 and the one or more obstacles is below the threshold value.
[034] Further, the control unit 102 is configured to provide a collision alert to the rider when the distance between the rear portion of the vehicle 126 and the one or more obstacles is below a critical value. The term, “collision alert” refers to an alert raised for the rider of the vehicle 126 when the rear portion of the vehicle 126 is in proximity of an obstacle along the travel path, within a distance below the critical value during the reverse riding mode. In one embodiment, the critical value is 50 cm. The one or more alerting devices 110 is configured to provide the collision alert to the rider through one of the visual alert, the audible alert, and the haptic alert via the instrument cluster 108 or the blinking LEDs, the audible device 128, and the haptic device 130, respectively. In one example, the one or more alerting devices 110 is configured to provide the collision alert to the rider when the distance between the rear portion of the vehicle 126 and the one or more obstacles is below 30 cm.
[035] In one embodiment, the control unit 102 is configured to generate the rendered view that indicates the plurality of adaptive lines 136, 138, 140 on the path 134 by detecting the determined one or more obstacles. As a result, the rider is assisted by the system 100 to avoid the one or more obstacles during the reverse riding mode of the vehicle 126.
[036] Figure 4 is the rendered view displayed on the display device 124 of a vehicle, in accordance with an embodiment of the present invention. The plurality of adaptive lines 136, 138, 140 comprises projection lines 136 indicating the path 134 determined through the adaptive-line generation model based on the steering angle and the inclination of the vehicle 126. In one embodiment, the projection lines 136 may be curved lines. The projection lines 136 indicate the path that the rider can consider for the reverse riding, and thus assist the rider in steering the vehicle 126 during the reverse riding.
[037] The plurality of adaptive lines 136, 138, 140 comprises a distal line 138 indicating a maximum distance based on the projection lines 136. In one embodiment, the distal line 138 is a straight line connecting maximal end points of the projection lines 136. The maximum distance may refer to a maximum reverse drivable distance by the vehicle 126. The plurality of adaptive lines 136, 138, 140 comprises a proximal line 140 indicating an intermediate distance based on the projection lines 136. In one embodiment, the proximal line 140 is a straight line connecting intermediate points of the projection lines 136. The intermediate distance may refer to an intermediate reverse drivable location by the vehicle 126. In an embodiment, the proximal line 140 may be positioned at a distance equal to the critical value of the one or more obstacles from the rear portion of the vehicle 126. In another embodiment, the distal line 138 may be positioned at a distance equal to the threshold value of the one or more obstacles from the rear portion of the vehicle 126. As such, the distal line 138 and the proximal line 140 provide an indication or a perception of the distance between the rear portion of the vehicle 126 and the obstacle.
[038] In one embodiment, when the rider steers the vehicle 126 towards left in the reverse riding mode, the projection lines 136 bend towards left on the display device 124, and when the rider steers the vehicle 126 towards right in the reverse riding mode, the projection lines 136 bend towards right on the display device 124. As such, the projection lines 136 adapt based on the direction of the steering unit and the inclination of the vehicle 126, thereby providing accurate depiction of the travel path taken by the vehicle 126 during reverse riding. The distal line 138 and the proximal line 140 are displayed in accordance with the projection lines 136.

Further, the adaptive line generation unit 114 determines the steering angle based on the steering angle data and the inclination of the vehicle 126 based on the roll angle data. Further, the adaptive line generation unit 114 is configured to determine the plurality of adaptive lines 136, 138, 140 based on the steering angle and the inclination of the vehicle 126. The adaptive line generation unit 114 combines the image data and the plurality of adaptive lines 136, 138, 140 to generate the rendered view indicating the path 134 superimposed on the image data. The generated rendered view is transmitted to the display device 124 by the control unit 102.
[043] The plurality of adaptive lines 136, 138, 140 provide reverse riding assistance to the rider by indicating a guided direction on the path 134. The rider is assisted in steering the steering unit during the reverse riding of the vehicle 126 due to the path 134 formed by the plurality of adaptive lines 136, 138, 140. The plurality of adaptive lines 136, 138, 140 move left and right in correlation to the steering angle and the inclination of the vehicle 126.
[044] The image processing unit 114 is communicatively coupled with the neural network unit 120 of the depth estimation unit 116. The neural network unit 120 is adapted to estimate the distance between the rear portion of the vehicle 126 and the one or more obstacles. When the estimated distance is below the threshold value or the critical value, the one or more alerting devices 110 is configured to alert the rider or provide the collision alert to the rider, respectively, through one of the visual alert, the audible alert, and the haptic alert.
[045] Figure 6 is a flow chart illustrating a method 600 for providing riding assistance to the rider during the reverse riding mode of the vehicle 126, in accordance with an embodiment of the present invention.
[046] At step 602, the control unit 102 receives the image data from the image sensor 104 mounted on the vehicle 126, the steering angle data from the steering angle sensor 106 coupled to the steering unit of the vehicle 126 and the roll angle data from the roll sensor 108 mounted on the vehicle 126.
[047] Thereafter, at step 604, the control unit 102 determines the steering angle of the vehicle 126 based on the steering angle data, and the inclination of the vehicle 126 based on the roll angle data.
[048] At step 606, the control unit 102 determines the plurality of adaptive lines 136, 138, 140 to indicate the path 134 for the reverse riding of the vehicle 126 based on the steering angle and the inclination of the vehicle 126, as already described in description pertaining to Figures 2-4. Subsequently, the control unit 102 determines the one or more obstacles along the path 134 for the reverse riding of the vehicle 126 through the image classification technique of the adaptive-line generation model. The control unit 102 then provides the first notification to the rider upon determining the one or more obstacles along the path of the reverse riding of the vehicle 126.

In an embodiment, the method 600 comprises the control unit 102 operating the display device 124 for providing the first notification to the rider as the visual notification. Thereafter, the depth estimation unit 116 of the control unit 102 estimates the distance between the rear portion of the vehicle 126 and the one or more obstacles. The control unit 102 then alerts the rider of the vehicle 126 through the one or more alerting devices 110, when the distance between the rear portion of the vehicle 126 and the one or more obstacles is below the threshold value.
[049] At step 608, the control unit 102 generates the rendered view indicating the path 134 superimposed on the image data, the rendered view is based on the image data and the plurality of adaptive lines 136, 138, 140.
[050] Subsequently, at step 610 the control unit 102 transmits the rendered view to the display device 124. The display device 124 is adapted to display the rendered view to the rider thereby providing riding assistance during the reverse riding mode of the vehicle 126. Subsequently, the rider is alerted by one of the visual alert, the audible alert and the haptic alert, when the distance between the rear portion of the vehicle 126 and the one or more obstacles is below the threshold value. The control unit 102 also provides the collision alert to the rider when the distance between the rear portion of the vehicle 126 and the one or more obstacles is below the critical value.
