Design and Development of Delayed Closing Function of Vehicle Electric Back Door

Li Guang Xie Zhipeng Fu Lingyu Wu Jiajia Liao Pingwei

Abstract：When the user parks the vehicle and prepares to remove the large luggage from the trunk， at this time， he is holding the luggage with both hands and cannot free his hands to operate the electric back door switch， and can only put the luggage on the ground before operating the electric back. The door can be opened and closed to complete the closing of the trunk， which cannot well reflect the convenience and value of the electric back door.This problem can be solved by the following discussion. The user needs to carry the vehicle's smart key， and the delayed closing function of the electric back door can be activated by double-clicking the closing switch of the electric back door; when this function is activated， there is a 30-second validity period. During these 30 seconds， the built-in buzzer of the electric rear door module will emit a periodic beep to indicate that this function is activated; in the first 10 seconds， the buzzer frequency is relatively slow， and when the second 10 seconds is entered The calling frequency of the buzzer is relatively rapid. If the calling frequency of the buzzer is very urgent in the last 10 seconds， the buzzer will stop calling until the 30 seconds are used up， and the function will automatically execute a timeout exit， and the electric back door will remain The current static state.However， if the user leaves the back door area of the vehicle with the smart key during the activation period of this function， the electric back door will immediately execute the automatic closing function， and when the back door is completely closed， the vehicle will automatically close. Perform the lock function; if the user does not want to use the delayed closing function of the electric back door， directly press the closing switch of the electric back door， then the electric back door exits the delayed closing function and immediately executes the automatic closing function.
