摘 要：當(dāng)用戶停好車輛，準備從后備箱搬走較大行李，這時雙手抱著行李箱，無法空出手來操作電動后背門開關(guān)，只能將行李箱放地上再去操作電動后背門開關(guān)，才能完成后備箱關(guān)閉，由此不能很好的體現(xiàn)出電動后背門的便利性和價值性。可以通過以下論述來解決此問題，需要用戶攜帶車輛智能鑰匙，通過連按兩下電動后背門的關(guān)閉開關(guān)可激活電動后背門延遲關(guān)閉功能;當(dāng)此功能被激活后有30秒的有效期，在這30秒內(nèi)電動后背門模塊的內(nèi)置蜂鳴器將發(fā)出周期提示音，用來提示這個功能被激活;在前10秒蜂鳴器鳴叫頻率比較緩和，當(dāng)進入第二個10秒時蜂鳴器名叫頻率比較急促，若進入最后10秒時蜂鳴器名叫頻率將非常緊急，直到這30秒時間用完蜂鳴器停止名叫，該功能自動執(zhí)行超時退出，電動后背門保持當(dāng)前靜止狀態(tài)。但是若在此功能的激活有效期內(nèi)，用戶抱著行李箱帶著智能鑰匙離開車輛后背門區(qū)域，電動后背門則立即執(zhí)行自動關(guān)閉功能，并且當(dāng)后背門完全關(guān)閉好以后，整車自動執(zhí)行上鎖功能;尚若用戶不想使用電動后背門延遲關(guān)閉功能，直接按下電動后背門的關(guān)閉開關(guān)，這時電動后背門退出延遲關(guān)閉功能并且立即執(zhí)行自動關(guān)閉功能。

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.
