[0001] TITLE OF INVENTION
[0002] A System for Providing Reverse Riding Assistance in a Vehicle and a Method Thereof
[0003] FIELD OF THE INVENTION
[0004]
[0001] The present invention generally relates to a vehicle. More particularly, the present invention relates to a system and a method for providing reverse riding assistance in the vehicle.
[0005] BACKGROUND OF THE INVENTION
[0006]
[0002] Riding assistance technologies are gaining popularity in recent years. The riding assistance technologies help users safely and efficiently maneuver a vehicle. The riding assistance technologies helps in assisting the user of the vehicle in maintaining the control of the vehicle. Similarly, reverse riding assistance helps the user maneuver the vehicle in reverse mode. A reverse lighting system such as a reverse lamp is provided in the vehicle for illuminating a region near the vehicle when the vehicle is in the reverse mode.
[0007]
[0003] Currently, the reverse lamp in the vehicle remains continuously illuminated when the vehicle is in the reverse mode. The continuous illumination of the reverse lamp causes several concerns. One of the primary concerns is that the constant illumination leads to confusion, especially in environments where multiple vehicles are present. The reverse lamp, when illuminated without any variation in intensity, is mistaken for other vehicle lights, such as brake lights or tail lamps. This further leads to a safety risk and creates confusion, particularly for the pedestrians who may not immediately recognize that the vehicle is in the reverse mode, as there is no distinct signal indicating the reverse mode of the vehicle.
[0008]
[0004] Additionally, the steady and uninterrupted illumination of the reverse lamp is dangerous, as it becomes difficult for both the users of other vehicles and pedestrians to distinguish between the reverse lamp and other vehicle signals. Further, when the pedestrians are unaware of the movement of the vehicle and thereverse lamp is constantly illuminated, leads to accidents, particularly in areas with high foot traffic like parking lots or residential streets.
[0009]
[0005] Another significant issue with the current reverse lamp in the vehicle is the impact on the electrical system of the vehicle. Since the reverse lamps remain continuously illuminated, they consume power over extended periods, especially in situations where the vehicle is stationary for a longer duration while reversing or parking. Additionally, the continuous operation of the reverse lamp draws power from the vehicle’s battery, leading to unnecessary energy consumption. This continuous power consumption drains the battery, especially in older vehicles with less efficient power systems, as it leads to battery depletion over time. Moreover, the higher power consumption directly impacts the vehicle's fuel efficiency and overall energy management.
[0010]
[0006] Also, the constant illumination of the reverse lamp contributes to the overheating of the reverse lamp itself, especially in cases where the reverse operations are conducted frequently or for extended periods, such as in crowded or tight parking spaces. The overheating damages the reverse lamp due to prolonged periods of heat buildup, thereby causing premature failure of the bulbs, degradation of the lamp housing, reduced performance over time and reduces the operational lifespan of the reverse lamp. As a result, the vehicle users face the inconvenience, thereby increasing the cost of replacing the reverse lamp more often than necessary. Further, the excessive heat damages the vehicle's electrical system.
[0011]
[0007] Therefore, the continuous operation of the current reverse lamps not only poses safety hazards by causing confusion among other drivers and pedestrians but also leads to power wastage, overheating, and reduced lifespan of the reverse lamps. This further leads to issues related to both safety and the efficiency of the vehicle lighting systems, which is undesirable.
[0012]
[0008] Thus, there is a need in the art for a system and method for providing reverse riding assistance in a vehicle which addresses the aforementioned problems.

[0030] DETAILED DESCRIPTION OF THE INVENTION
[0031]
[0022] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder.
[0032]
[0023] The present invention relates to a system and a method for providing reverse riding assistance in a vehicle. The system and method of the present invention provides a dynamic operation of a reverse illumination system when the vehicle isin the reverse mode. The present invention helps in addressing the visibility of the vehicle in the reverse mode and the need for providing the real-time alerts to a user and pedestrians. The system and the method of the present invention provides a comprehensive safety to the other users and the pedestrians, thereby minimizing the risk of accidents and ensuring the reverse mode of the vehicle is safe.
[0033]
[0024] The system and method of the present invention are typically used in the vehicle such as a two-wheeled vehicle, or a three-wheeled vehicle including trikes, or a four-wheeled vehicle, or other multi-wheeled vehicles as required. The system and method of the present invention are typically used in the vehicle such as internal combustion engine (ICE) vehicles, electric vehicles or hybrid vehicles as required.
[0034]
[0025] Figure 1 illustrates a schematic diagram of the system 100 for providing reverse riding assistance in the vehicle 10, in accordance with an embodiment of the present invention. The system 100 is implemented in the vehicle 10 to provide the reverse riding assistance to the user. As disclosed herein, the “reverse riding assistance” refers to an assistance provided to the user of the vehicle 10 when the vehicle is in the reverse mode.
[0035]
[0026] The system 100 includes one or more sensors 102. The one or more sensors 102 are disposed in the vehicle 10. The one or more sensors 102 detect one or more parameters surrounding the vehicle 10 in real-time. The one or more parameters correspond to an obstacle information surrounding the vehicle 10 in the real time. In an embodiment, each of the one or more sensors 102 are adapted to determine the obstacle information in real-time during the reverse riding of the vehicle 10. The one or more sensors 102 are adapted to detect the obstacle near the vehicle 10 when the vehicle 10 is in the reverse mode.
[0036]
[0027] In a non-limiting embodiment, the one or more sensors 102 include but not limited to an ultrasonic sensor 102a, a Radio Detection and Ranging (RADAR) sensor 102b, an image sensor 102c, and a Light Detection and Ranging (LIDAR) sensor. The ultrasonic sensor 102a is adapted to detect the obstacle from the vehicle 10 in the real-time. The radar sensor 102b is adapted to determine a distance of the obstacle from the vehicle 10 in the real-time. The image sensor 102c is adapted to generate image information of the obstacle from the vehicle 10 in the real-time. TheLIDAR sensor is also adapted to generate obstacle information pertaining to an obstacle detection in the real-time.
[0037]
[0028] In a working example, a Rear Parking Assist Sensor (RPAS) is provided in the vehicle 10. The RPAS plays a critical role in detecting the obstacles behind the vehicle 10, particularly when reversing or parking the vehicle 10. In a non-limiting embodiment, the RPAS is disposed at predetermined points around a rear bumper of the vehicle 10. The RPAS uses an ultrasonic or electromagnetic technology to measure the distance between the vehicle and the obstacle behind the vehicle 10. As the vehicle 10 reverses, the RPAS continuously scans the space behind the vehicle 10 to identify any potential hazards, such as other vehicles, pedestrians, bicycles, or stationary objects like walls and curbs. The RPAS processes the data and alerts the user of the vehicle 10 in the real-time, typically through a combination of auditory beeps that increase in frequency as the vehicle 10 gets closer to the obstacle, and visual warnings that appear on an instrument cluster within the vehicle 10. This helps the user avoid collisions, especially in situations where the visibility is compromised, such as in tight parking spaces or when reversing the vehicle 10 into busy areas. Therefore, the RPAS contributes to reducing accidents by improving the user’s situational awareness, thereby improving the parking accuracy and ensuring the safety of the pedestrians and other road users.
[0038]
[0029] The system 100 has an illumination assembly 104 having at least one illumination source. In a non-limiting embodiment, the illumination assembly 104 is a reverse lamp disposed on the vehicle 10. The illumination assembly 104 is disposed on a rear end of the vehicle 10. In a non-limiting embodiment, the illumination assembly 104 is disposed on the rear bumper of the vehicle 10. The illumination assembly 104 is operable to illuminate a rear region surrounding the vehicle 10 during the reverse riding of the vehicle 10.
[0039]
[0030] In a working example, the reverse lamp serves as a dual purpose i.e., by providing illumination to the area behind the vehicle 10 during low-light or nighttime conditions and signalling to other road users and the pedestrians that the vehicle 10 is in the reverse mode. When the vehicle 10 is in the reverse mode, the reverse lamp is automatically activated to light up the space behind the vehicle 10,thereby offering better visibility for both the user and for others in the surrounding environment. This is particularly useful in dimly lit parking areas, dark streets, or during night-time parking maneuvers, where the obstacles may not be easily visible. Additionally, the reverse lamp acts as a safety indicator, alerting the pedestrians and other users that the vehicle 10 is moving backward. This visual signal thereby helps in preventing the accidents by warning nearby individuals to stay clear of the vehicle’s path. The reverse lamp ensures that the vehicle’s intention to reverse is clear to everyone in the vicinity, thereby enhancing safety in environments where the user’s view is limited, and helping to avoid collisions with the pedestrians, cyclists, or other vehicles.
[0040]
[0031] The system 100 has a control unit 108 communicatively coupled to the one or more sensors 102 and the illumination assembly 104. The control unit 108 is a centralized unit in the system 100 that manages and coordinates various components and functions through data processing and signal generation. The control unit 108 is the central brain of the electronic system of the vehicle 10. The control unit 108 acts as the master controller, by receiving the inputs from various vehicle components like a direction selection switch, the RPAS sensors, the reverse lamps, a reverse beeper unit 106, and other sensors 102 that provide the real-time data. The control unit 108 processes the information and makes decisions based on the vehicle’s operational state and environmental conditions.
[0041]
[0032] The control unit 108 receives an input from the user of the vehicle 10 for providing the reverse riding assistance in the vehicle 10. In a non-limiting embodiment, the control unit 108 is communicably coupled to an infotainment system of the vehicle 10. The infotainment system receives the input from the user for providing the reverse riding assistance in the vehicle 10. In a non-limiting embodiment, the infotainment system is the instrument cluster of the vehicle 10.
[0042]
[0033] In an embodiment, the system 100 has a direction control switch 110. The direction control switch 110 is disposed in the vehicle 10. The direction control switch 110 (Drive, Reverse, Neutral) allows the user to select the desired movement direction or state of the vehicle's transmission. The direction control switch 110 is communicatively coupled to the control unit 108. The direction control switch 110receives the input from the user and sends the input received from the user of the vehicle 10 to the control unit 108 for providing the reverse riding assistance in the vehicle 10.
[0043]
[0034] In a working example, the direction selection switch 110 is a critical component that allows the user to control the direction of the vehicle’s movement. The direction selection switch 110 typically offers the options such as Drive, Reverse, and Neutral, thereby allowing the user to select the desired gear to control the vehicle's motion. The direction selection switch 110 serves as an interface between the user and the vehicle’s transmission system, thereby enabling the user to input the appropriate command for the vehicle’s operation. When the vehicle is placed into Reverse, the direction selection switch 110 signals the vehicle's control system that the vehicle 10 should start moving backward. This input is then processed by the control unit 108 to activate the corresponding systems such as the reverse lamps, RPAS sensors, and the reverse beeper unit 106 to ensure the vehicle’s movements are safe and well-communicated to other users and the pedestrians. The direction selection switch 110 provides an intuitive and reliable way for the user to select the appropriate gear, thereby ensuring the smooth and accurate vehicle operation.
[0044]
[0035] The control unit 108 compares the obstacle information determined by the one or more sensors 102 with one or more predetermined parameters related to an obstacle, based on the received input from the user for the reverse riding of the vehicle 10. In an embodiment, the one or more predetermined parameters include but are not limited to a presence of the obstacle near the vehicle 10, a predetermined distance of the obstacle from the vehicle 10, and the like. Based on the determination that the obstacle is present near the vehicle 10, the control unit 108 compares the obstacle information determined by the one or more sensors 102 with the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the predetermined distance of the obstacle from the vehicle 10 corresponds to five meters.
[0045]
[0036] Based on a comparison of the obstacle information with the one or more predetermined parameters related to the obstacle as described hereinabove, theillumination assembly 104 is operated to illuminate the rear region surrounding the vehicle 10. Therefore, the illumination assembly 104 is operated when the obstacle is determined in the rear region of the vehicle 10. Further, the control unit 108 also generates an alert to the user and the pedestrians of the vehicle 10, when the determined obstacle information exceeds the one or more predetermined parameters related to the obstacle. If the determined obstacle distance in the real-time is less than the predetermined distance of the obstacle as described hereinabove, then the control unit 108 generates the alert through a reverse beeper unit 106. In an embodiment, the system 100 generates the alert in at least one or more of: an audio alert through the reverse beeper unit 106, a visual alert through the illumination assembly 104, and a haptic alert. The alert is generated to the other users of the vehicles and the pedestrians.
[0046]
[0037] In an embodiment, the system 100 has the reverse beeper unit 106. The reverse beeper unit 106 is disposed on the vehicle 10 and communicatively coupled to the control unit 108. The reverse beeper unit 106 is operable to emit a beeping sound at a predetermined frequency during the reverse riding of the vehicle 10, when the determined obstacle information exceeds the one or more predetermined parameters related to the obstacle.
[0047]
[0038] The reverse beeper unit 106 is an essential auditory safety feature in the vehicle 10. The reverse beeper unit 106 is used to emit warning sounds or alerts to notify the users and the pedestrians about specific conditions or actions. In the context of reversing, the reverse beeper unit 106 emits a consistent audible alert that serves as a warning when the vehicle 10 is in the reverse mode. This sound alerts the pedestrians, cyclists, and other drivers who might not be able to see the vehicle’s reverse lamps or who may not be aware that the vehicle 10 is in the reverse mode. The reverse beeper unit 106 is often used in conjunction with other safety features such as RPAS sensors and reverse lamps, thereby adding an additional layer of safety to ensure that the individuals nearby are warned of the vehicle's reverse motion. The sound typically increases in frequency as the vehicle 10 gets closer to the obstacle or person, thereby providing real-time and proximity-based alerts. This helps to prevent collisions in situations where the visual cues are not sufficient, suchas when the user is unable to fully see behind the vehicle 10 or when the visibility is blocked by obstructions.
[0048]
[0039] Therefore, all the components of the system 100 work together to enhance the safety and efficiency of the vehicle operations during reversing and parking. The one or more sensors 102 detect the nearby obstacles, the illumination assembly 104 illuminates the area and signals the vehicle’s reverse motion, the reverse beeper unit 106 provides audible alerts to the pedestrians and drivers, the direction selection switch 110 allows the user to control the vehicle’s direction, and the control unit 108 ensures that all these systems work harmoniously to improve the vehicle’s safety features. Hence, the system 100 is designed to reduce accidents, enhance visibility, and create a safer environment for both the user and surrounding individuals.
[0049]
[0040] In an example, when a user ‘A’ selects Reverse on the direction selection switch 110, the control unit 108 receives the input and activates the reverse lamps 104, RPAS sensors 102, and the reverse beeper unit 106 accordingly. The present invention also adjusts the vehicle’s movement control to safely reverse the vehicle 10. The control unit 108 ensures that all the connected systems are properly coordinated, functioning as intended, and operating at optimal efficiency. The present invention plays a role in managing the system failures and troubleshooting by providing diagnostics for components that needs attention, thus ensuring the working condition of the vehicle's safety systems. The control unit 108 integrates all the functions and systems, thereby maintaining constant communication between all the units, thereby making the vehicle’s operation seamless, safe, and efficient.
[0050]
[0041] As described hereinbefore, the alert is generated to the user as well the pedestrians. However, the alert is generated based on the following conditions. If the determined obstacle information is greater than a first predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 in a continuous mode and operate the reverse beeper unit 106 in an OFF state. In a non-limiting embodiment, the first predetermined parameter corresponds to the predetermined distance of the obstacle from the vehicle 10 and the same is fivemeters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to a wall, obstacle, or the pedestrian exceeds five meters, then the tail lamp is continuously illuminated and the reverse beeper unit 106 is in an OFF state.
[0051]
[0042] Then, if the determined obstacle information is greater than a second predetermined parameter and less than the first predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 at a first illumination mode and operate the reverse beeper unit 106 at a first predetermined frequency. In a non-limiting embodiment, the first predetermined parameter and the second predetermined parameter correspond to the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the first predetermined parameter is five meters and the second predetermined parameter is four meters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to the wall, obstacle, or the pedestrian drops below five meters but the same exceeds four meters, then a tail lamp of the vehicle 10 is operated at the first illumination mode i.e., the tail lamp flickers and the reverse beeper unit 106 operates with the first predetermined frequency. In a non-limiting embodiment, the frequency of the reverse beeper unit 106 increases or decreases based on the distance of the vehicle 10 from the obstacle.
[0052]
[0043] Then, if the determined obstacle information is greater than a third predetermined parameter and less than the second predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 operates the illumination assembly 104 at a second illumination mode and operate the reverse beeper unit 106 at a second predetermined frequency. In a non-limiting embodiment, the second predetermined parameter and the third predetermined parameter correspond to the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the second predetermined parameter is four meters and the third predetermined parameter is three meters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to the wall, obstacle, or the pedestrian drops below four meters but the same exceeds three meters, then the tail lamp is operated at the second illumination mode i.e., the flickering intensity of thetail lamp increases and the reverse beeper unit 106 operates with the second predetermined frequency.
[0053]
[0044] Then, if the determined obstacle information is less than the third predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 at a third illumination mode and operates the reverse beeper unit 106 at a third predetermined frequency. In a non-limiting embodiment, the third predetermined parameter correspond to the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the third predetermined parameter is three meters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to the wall, obstacle, or the pedestrian drops below three meters, then the tail lamp is operated at the third illumination mode i.e., the flickering intensity of the tail lamp changes, and the user receives an additional indication through either a buzzer, light, or haptic feedback and the reverse beeper unit 106 operates with the third predetermined frequency.
[0054]
[0045] Figure 2 illustrates a method 200 for providing the reverse riding assistance in the vehicle 10, in accordance with an embodiment of the present invention. The method 200 starts at step 202. The method 200 is implemented in the vehicle 10 to provide the reverse riding assistance to the user. As disclosed herein, the “reverse riding assistance” refers to the assistance provided to the user of the vehicle 10 when the vehicle is in the reverse mode.
[0055]
[0046] At step 204, the method 200 includes the step of receiving, by the control unit 108, an input from the user of the vehicle 10 for providing the reverse riding assistance in the vehicle 10. The control unit 108 is communicatively coupled to the one or more sensors 102 and the illumination assembly 104. The control unit 108 is a centralized unit in the system 100 that manages and coordinates various components and functions through data processing and signal generation. The control unit 108 is the central brain of the electronic system of the vehicle 10. The control unit 108 receives the input from the user of the vehicle 10 for providing the reverse riding assistance in the vehicle 10. In a non-limiting embodiment, the control unit 108 is communicably coupled to an infotainment system of the vehicle 10. The infotainment system receives the input from the user for providing thereverse riding assistance in the vehicle 10. In a non-limiting embodiment, the infotainment system is the instrument cluster of the vehicle 10.
[0056]
[0047] In an embodiment, the direction control switch 110 is disposed in the vehicle 10. The direction control switch 110 is communicatively coupled to the control unit 108. The direction control switch 110 receives the input from the user and sends the input received from the user of the vehicle 10 to the control unit 108 for providing the reverse riding assistance in the vehicle 10.
[0057]
[0048] At step 206, the method 200 has the step of comparing, by the control unit 108, obstacle information determined by the one or more sensors 102 with the one or more predetermined parameters related to an obstacle, based on the received input from the user for the reverse riding of the vehicle 10. In an embodiment, the one or more sensors 102 are disposed in the vehicle 10. The one or more sensors 102 detect one or more parameters surrounding the vehicle 10 in real-time. In an embodiment, each of the one or more sensors 102 are adapted to determine the obstacle information in real-time during the reverse riding of the vehicle 10. The one or more sensors 102 are adapted to detect the obstacle near the vehicle 10 when the vehicle 10 is in the reverse mode. In an embodiment, the one or more predetermined parameters include but are not limited to a presence of the obstacle near the vehicle 10, a predetermined distance of the obstacle from the vehicle 10, and the like. Based on the determination that the obstacle is present near the vehicle 10, the control unit 108 compares the obstacle information determined by the one or more sensors 102 with the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the predetermined distance of the obstacle from the vehicle 10 corresponds to five meters.
[0058]
[0049] In a non-limiting embodiment, the one or more sensors 102 include but not limited to an ultrasonic sensor 102a, a Radio Detection and Ranging (RADAR) sensor 102b, an image sensor 102c, and a Light Detection and Ranging (LIDAR) sensor. The ultrasonic sensor 102a is adapted to detect the obstacle from the vehicle 10 in the real-time. The radar sensor 102b is adapted to determine a distance of the obstacle from the vehicle 10 in the real-time. The image sensor 102c is adapted to generate image information of the obstacle from the vehicle 10 in the real-time. TheLIDAR sensor is also adapted to generate obstacle information pertaining to an obstacle detection in the real-time.
[0059]
[0050] At step 208, the method 200 has the step of operating, by the control unit 108, the illumination assembly 104 to illuminate a rear region surrounding the vehicle 10 based on a comparison of the obstacle information with the one or more predetermined parameters related to the obstacle. The illumination assembly 104 has at least one illumination source. In a non-limiting embodiment, the illumination assembly 104 is a reverse lamp disposed on the vehicle 10. The illumination assembly 104 is disposed on a rear end of the vehicle 10. In a non-limiting embodiment, the illumination assembly 104 is disposed on the rear bumper of the vehicle 10. The illumination assembly 104 is operable to illuminate a rear region surrounding the vehicle 10 during the reverse riding of the vehicle 10.
[0060]
[0051] Based on a comparison of the obstacle information with the one or more predetermined parameters related to the obstacle as described hereinabove, the illumination assembly 104 is operated to illuminate the rear region surrounding the vehicle 10. Therefore, the illumination assembly 104 is operated when the obstacle is determined in the rear region of the vehicle 10.
[0061]
[0052] At step 210, the method 200 has the step of generating, by the control unit 108, an alert to the user of the vehicle 10, when the determined obstacle information exceeds the one or more predetermined parameters related to an obstacle. Therefore, the control unit 108 also generates an alert to the user and the pedestrians of the vehicle 10, when the determined obstacle information exceeds the one or more predetermined parameters related to the obstacle. If the determined obstacle distance in the real-time is less than the predetermined distance of the obstacle as described hereinabove, then the control unit 108 generates the alert through a reverse beeper unit 106. In an embodiment, the method 200 generates the alert in at least one or more of: an audio alert through the reverse beeper unit 106, a visual alert through the illumination assembly 104, and a haptic alert. The alert is generated to the other users of the vehicles and the pedestrians.
[0062]
[0053] In an embodiment, the reverse beeper unit 106 is disposed on the vehicle 10 and communicatively coupled to the control unit 108. The reverse beeper unit 106is operable to emit a beeping sound at a predetermined frequency during the reverse riding of the vehicle 10, when the determined obstacle information exceeds the one or more predetermined parameters related to the obstacle.
[0063]
[0054] As described hereinbefore, the alert is generated to the user as well the pedestrians. However, the alert is generated based on the following conditions. If the determined obstacle information is greater than a first predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 in a continuous mode and operate the reverse beeper unit 106 in an OFF state. In a non-limiting embodiment, the first predetermined parameter corresponds to the predetermined distance of the obstacle from the vehicle 10 and the same is five meters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to a wall, obstacle, or the pedestrian exceeds five meters, then the tail lamp is continuously illuminated and the reverse beeper unit 106 is in an OFF state.
[0064]
[0055] Then, if the determined obstacle information is greater than a second predetermined parameter and less than the first predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 at a first illumination mode and operate the reverse beeper unit 106 at a first predetermined frequency. In a non-limiting embodiment, the first predetermined parameter and the second predetermined parameter correspond to the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the first predetermined parameter is five meters and the second predetermined parameter is four meters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to the wall, obstacle, or the pedestrian drops below five meters but the same exceeds four meters, then the tail lamp is operated at the first illumination mode i.e., the tail lamp flickers and the reverse beeper unit 106 operates with the first predetermined frequency.
[0065]
[0056] Then, if the determined obstacle information is greater than a third predetermined parameter and less than the second predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 operates the illumination assembly 104 at a second illumination mode and operate the reverse beeper unit 106 at a second predetermined frequency. In a non-limitingembodiment, the second predetermined parameter and the third predetermined parameter correspond to the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the second predetermined parameter is four meters and the third predetermined parameter is three meters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to the wall, obstacle, or the pedestrian drops below four meters but the same exceeds three meters, then the tail lamp is operated at the second illumination mode i.e., the flickering intensity of the tail lamp increases and the reverse beeper unit 106 operates with the second predetermined frequency.
[0066]
[0057] Then, if the determined obstacle information is less than the third predetermined parameter related to the obstacle, then the control unit 108 operates the illumination assembly 104 at a third illumination mode and operates the reverse beeper unit 106 at a third predetermined frequency. In a non-limiting embodiment, the third predetermined parameter correspond to the predetermined distance of the obstacle from the vehicle 10. In a non-limiting embodiment, the third predetermined parameter is three meters. Therefore, when the vehicle 10 is in the reverse mode, if the distance to the wall, obstacle, or the pedestrian drops below three meters, then the tail lamp is operated at the third illumination mode i.e., the flickering intensity of the tail lamp changes, and the user receives an additional indication through either a buzzer, light, or haptic feedback and the reverse beeper unit 106 operates with the third predetermined frequency. The method 200 subsequently terminates at step 212.
[0067]
[0058] In a working example, a user ‘B’ is riding a four wheeled vehicle i.e. a car. The user B has to park the car in a closed area with less space. The user ‘B’ starts the reversing the car. The sensors and the reverse lamps are activated. The sensors continuously detect the obstacles behind the car i.e., other cars parked in the area and the walls behind the car. The distance between the car and the obstacles is determined as 7 meters. Based on the determination, only the reverse lamps are activated and illuminated continuously. When the distance starts decreasing and becomes 3 meters, then the reverse lamps start flickering and the reverse beeper unit in the car generates the alert for the user as well other pedestrians on the roadwith the combination of the one or more of the audio alert and the haptic alert, thereby enhancing the safety of the user and the pedestrians.
[0068]
[0059] Figure 3 illustrates yet another flow chart of the method 300 for providing the reverse riding assistance in the vehicle 10, in accordance with an exemplary embodiment of the invention. As illustrated, the method 300 starts at step 302. At step 304, the system 100 is initialized and the ignition of the vehicle 10 is ON. At step 306, the method 300 checks whether the vehicle 10 is in the reverse mode. If the vehicle 10 is not in the reverse mode, then the method 300 is terminated as shown at step 318.
[0069]
[0060] However, if the vehicle 10 is in the reverse mode, then at step 308, the one or more sensors 102 are initialized and enabled. The initialization of the one or more sensors 102 such as LIDAR, Radar, and ultrasonic systems ensures that the one or more sensors 102 are correctly calibrated and operational. The one or more sensors 102 detect obstacles, measure distances between the vehicle 10 and the obstacle, and monitor the environment around the vehicle 10. The one or more sensors 102 is a Rear Parking Assist Sensor (RPAS), as described hereinabove. The RPAS detects the obstacles behind the vehicle 10 during reversing and parking maneuvers. The RPAS provides real-time alerts to the user, typically through audible or visual signals, thereby helping the user to prevent collisions, improve parking accuracy, and enhance safety for the pedestrians, cyclists, and other nearby obstacles.
[0070]
[0061] At step 310, the method 300 checks if the obstacle distance is above the predetermined threshold. The predetermined threshold is five meters. If the obstacle distance is above the predetermined threshold, then as shown at step 312, the illumination assembly 104 is operated at continuous ON state and the reverse beeper unit 106 is kept at OFF state, thereby indicating that the distance between the obstacle and the vehicle is not crucial. The reverse lamp is to illuminate the area behind the vehicle and signal to others that the vehicle 10 is in the reverse mode. This helps to alert the pedestrians and other users of the vehicle's intention to move backward, thereby enhancing safety and visibility during reversing maneuvers, especially in low-light conditions.
[0062] However, if the obstacle distance is below the predetermined threshold, then as shown at step 314, the illumination assembly 10 is operated with flickering intensity and the reverse beeper unit 106 is operated to generate the alert, thereby indicating that the distance between the obstacle and the vehicle is crucial. As shown at step 316, the alert is generated to the user and the pedestrians through a combination of one or more of: an audio alert through the reverse beeper unit 106, a haptic alert and a lighting system alert through the illumination assembly 104. The reverse beeper unit 106 emits audible alerts or warning sounds to signal certain actions or conditions in the vehicle 10. The reverse beeper unit 106 are often used to notify the users and pedestrians when the vehicle 10 is reversing, thereby helping to improve safety by alerting those nearby the vehicle 10. The method 300 subsequently terminates at step 318.
[0071]
[0063] Advantageously, the present invention helps in providing the assistance to the user during the reverse riding of the vehicle. The present invention helps in providing enhanced comfort to the user and provides better control to the user, thereby enhancing the riding experience of the user. The system and the method of the present invention helps in preventing accidents, enhances road safety, improves confidence and comfort of the user, thereby making the system and the method an essential step towards more advanced and user-friendly autonomous systems. The present invention operates on real-time data from various one or more sensors, an intelligent decision-making process, and a control unit to monitor the vehicle’s environment.
[0072]
[0064] The present invention improves safety of the pedestrians and other users of the vehicles. The present invention provides an adaptive reverse light system that better signals the intention of the vehicle to move in reverse, thereby improving pedestrian awareness. The present invention provides a pulsing or flashing light (or varying intensity of the light), thereby drawing more attention and ensuring that the pedestrians are aware of the vehicle’s movement. This targeted visibility reduces accidents, enhances pedestrian safety, and make the vehicle's reverse action more discernible in busy environments. The present invention incorporates a dynamic signalling system (such as blinking or changing light intensity) that is specificallytied to the reverse operation, therefore, the pedestrians are able to immediately identify that the vehicle is moving backward. This helps to differentiate the reverse lamps from other vehicle lights, thus preventing any misinterpretation of the vehicle’s intentions and improving overall pedestrian safety.
[0073]
[0065] The present invention includes an automatic dimming system or an advanced heat dissipation system that reduces the amount of energy used by the reverse lamps. The present invention prevents the potential damage to the reverse lamp and improves the durability and lifespan, by reducing the heat generated through controlled lighting. The introduction of changing intensity of the reverse lamps significantly cut down on power consumption. The overall energy use is minimized, thereby leading to less strain on the battery and improved vehicle efficiency. Additionally, the energy-efficient LEDs generates less heat, further contributing to the overall reduction in the power consumption.
[0074]
[0066] Furthermore, the present invention focuses on safeguarding both the pedestrians and drivers during the critical maneuver of vehicle reversing. The present invention addresses the key safety concerns by enhancing visibility, increasing awareness, and providing the real-time alerts to the users and pedestrians. Usually, the reverse riding of the vehicle is performed in areas with limited visibility such as parking lots, narrow driveways, and residential streets, which poses significant risks to the pedestrians, cyclists, and other drivers. To mitigate these risks, the present invention incorporates the system and method that works seamlessly together to provide an additional layer of protection during the reverse riding of the vehicle.
[0075]
[0067] The present system ensures that the pedestrians are alerted in a timely and clear manner whenever the vehicle is reversing, even if they are out of the user’s direct line of sight. This is accomplished through a combination of the visual signals, such as illuminated reverse lamps, and audible beeping sounds from the reverse beeper unit, which increases in intensity as the vehicle gets closer to the obstacle or individual. The system alerts the pedestrians in environments where they may not notice the vehicle moving backward, thereby helping to prevent accidents that could occur due to the pedestrian inattention or lack of awareness.
[0068] For the user, the system enhances situational awareness by detecting the potential obstacles behind the vehicle, such as other vehicles, parked objects, or the pedestrians. The RPAS continuously monitors the space behind the vehicle and provides real-time alerts through visual and audible cues. This allows the user to make more informed decisions while reversing, thereby improving parking accuracy and reducing the likelihood of collisions. By offering a comprehensive safety net that detects, alerts, and informs, the present invention assists the user in maneuvering safely, even in complex or crowded environments.
[0076]
[0069] The control unit allows for the seamless integration and coordination of the safety features. The control unit processes inputs from various sensors and systems, thereby ensuring that each component function in synchronization with each other. When the vehicle is in the reverse mode, the control unit activates the reverse lamps, the RPAS, and the reverse beeper unit, while monitoring the surrounding environment to ensure safe vehicle movement. This helps in not only preventing accidents but also to make reversing and parking tasks efficient for the user. The present invention provides the system and the method with advanced technology which helps to create a safer vehicle reversing experience by reducing human error, thereby offering timely warnings, and making both the pedestrians and the users more aware of the surroundings.
[0077]
[0070] The present invention prioritizes the protection of the pedestrians, users, and vehicles through smart and responsive systems. The present invention further provides for continued monitoring of the environment around the vehicle to detect obstacles, thereby enhancing the safety of the user. Hence, the present invention provides for the system and the method which is effective, safe, and cost-efficient.
