Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of vehicle doors anti-pinchtechnology. More particularly the present disclosure relates to a system and methodfor monitoring and operating vehicle door positions to prevent pinching accidents.BACKGROUND

[0002] The following description of the related art is intended to providebackground information pertaining to the field of the present disclosure. Thissection may include certain aspects of the art that may be related to various featuresof the present disclosure. However, it should be appreciated that this section is usedonly to enhance the understanding of the reader with respect to the presentdisclosure, and not as admissions of the prior art.

[0003] In recent years, advancements in automobile technology have significantlyimproved the overall safety of vehicles, focusing on protecting both occupants andpedestrians from potential accidents and collisions. However, despite theseadvancements, certain areas of vehicle safety, such as door mechanisms, still posechallenges and risks. Pinching accidents, where fingers, hands, or other objects gettrapped in closing doors, continue to be a concern in automobile safety.Recognizing this safety concern, researchers and engineers have diligently soughtinnovative solutions to mitigate the risk of pinching accidents.

[0004] Generally, the existing systems have integrated various technologies toenhance passenger and pedestrian safety. The technologies include mechanicalpadding, retraction mechanisms, pneumatic actuation systems, infrared (IR)sensors, and pressure sensors. The existing system with mechanical padding is usedto soften the impact of closing doors. However, these systems do not proactivelyprevent accidents and merely mitigate the force upon contact. The existing systemwith a retraction mechanism is used to halt the door's motion upon detecting anobstruction. The retraction mechanism includes complexities that lead to delayedresponses and raise concerns about reliability. Further, the existing system withpneumatic actuation includes complexities related to maintenance, fluid leaks, andsystem reliability. The complexities of pneumatic actuation may compromiseresponse time and effectiveness.

[0005] Furthermore, the existing systems relying on infrared (IR) or pressuresensors can be limited in accuracy, particularly when dealing with obstacles ofvarying profiles, leaving gaps in coverage. Traditional systems that use complexcomputational methods for obstacle detection face processing delays and potentialactuation issues, compromising the essential real-time responsiveness needed toprevent accidents. Traditional systems may include viewing angle issues and line-of-sight obstructions that pose challenges, creating blind spots and leavingvulnerabilities in detection. Additionally, the limited adaptability of many existingsystems to diverse door frame shapes and vehicle designs hampers theireffectiveness across a wide array of automobile models. In addition, sensor-basedsystems may trigger false positives due to changing lighting conditions or non-obstructive reflections, leading to unnecessary halts and inconveniences, therebyreducing the system's reliability.

[0006] Moreover, existing technologies often struggle to adapt to the diverse doorframe topologies that originate in different vehicle designs. This limitationcompromises the consistent and reliable performance of safety systems.Conventional systems may not accurately identify various types of obstacles,leading to false positives or missed detections, hampering the system's ability toprovide comprehensive protection. Additionally, some existing technologiesexhibit delays in detecting obstacles and initiating preventive actions, reducing thesystem's effectiveness in preventing accidents and ensuring occupant safety.Therefore, there is a need to develop a system to resolve critical safety concernsassociated with the existing automobile door safety systems, particularly thelimitations of cross-compatibility, multi-category obstacle detection, and speed ofactuation.

[0007] There is, therefore, a need in the art to provide a system and method that canovercome the shortcomings of the existing prior arts.OBJECTS OF THE PRESENT DISCLOSURE

Therefore, the system 102 can be activated when the door is in apartially open or partially closed state, specifically when the potentiometer's signalfalls between the values 200 and 800. If the analog signal is less than 200 or greaterthan 800, the system remains inactive, corresponding to the door being either fullyclosed or fully open, respectively. This specific range (200 to 800) is an exampleand can be adjusted based on the requirements and design specifications of thesystem.
