Projeto de limitador eletromagnético para porta automotiva com sensoriamento anticolisão

Abstract

With the objective of assisting in the construction of a safe transit and creating facilities in the embarkation and disembarkation of an automobile, the current work presents the development of a prototype of electromagnetic check link for the automotive door that interacts with sensors located on the side and rear of the car. Such a system detects moving bodies that are approaching the opening area of the door or static bodies that are within the opening area. The electromagnetic check link blocks the opening of the door and prevents accidents during the passage of bicycles, motorcycles and other vehicles, as well as avoids collisions with parked vehicles, poles, dumps or walls. The results show that an ultrasound sensor is the most suitable for the system, besides the use of a coil in the check link creates an opening resistance force. For the measured force values, the actuator performs the lockout, but to create a noticeable resistance for the occupants one must make changes to the actuator, be it size, number of turns and applied current. Future work aims to maximize actuator strength and develop a specific rod for the electromagnetic check link, optimizing the work of the assembly. [resumo fornecido pelo autor]
