System and method for protecting electric tail gate stay bar

Abstract

The invention relates to a system and method for protecting an electric tail gate stay bar. The system comprises a stay bar motor, a Hall signal collector connected with the stay bar motor, a motor current collector connected with the stay bar motor, and a master control CPU connected with the motor current collector. A motor stroke processing unit is arranged in the master control CPU. The system and the method solve the problems that when an electric tail gate is in a stop state, the stay bar is extremely prone to damage due to the man-made electric tail gate pulling and dragging behavior; the service life of the electric tail gate is further improved, the reliability of the electric tail gate is improved, whether the electric tail gate of an automobile is in a man-made pulling and dragging state or not can be judged through the system, the stroke speed of the stay bar motor can be correspondingly adjusted, the current of the stay bar motor can be reduced through the system in time, and meanwhile an automobile owner can know that the electric tail gate has automatic opening and automatic closing functions. The system is low in using cost, convenient and fast to use and good in using effect.

Description

Technical field [0001] The invention relates to the automobile industry and the field of electric tailgates, and in particular to a system and method for protecting an electric tailgate brace. Background technique [0002] At present, most electric tailgates have added anti-pinch function and motor overcurrent protection function. This is to protect the electric tailgate during the electric opening or closing process, but in practical applications, when the electric tailgate is stopped In the state of (that is, when the strut motor is under braking), some car owners are too impatient or do not know that the tailgate has an electric function, so the car owner directly pulls the tailgate by hand and wants to open or close the door as soon as possible purpose. When the owner exerts too much force or pulls for too long, the internal components of the strut will be overloaded, which can easily damage the internal structure of the electric strut, and sometimes even directly cause the ...

AI Technical Summary

Problems solved by technology

When the owner uses too much force or pulls for too long, the internal components of the strut will rotate with overload, which will easily cause damage to the internal structure of the electric strut, and sometimes even directly cause the strut to fail to work.
