摘要 本文首先簡單概述了電動車窗在國內外的發(fā)展，以電動車窗取代了傳統(tǒng)的手搖車窗，隨后介紹了舊款車型的控制電路，引出了容易被夾的安全問題以及容易被盜的隱患，應該要被另一種新型電路來取代，以實現人們對舒適性與安全性的期望。 新款的電動車窗控制電路與舊電路相比，不僅延續(xù)了其簡單的原理，而且提出了利用先進的芯片技術來控制車窗，并按照實際所需選擇了TLC2543 作為MICU 的芯片部分，詳細解釋加入芯片后的車窗電路的控制原理，實現了更有利于人與車的防夾功能。同時設定了汽車軟硬件，通過分析內部芯片的變化情況，檢測出車窗的運行狀態(tài)，即當有物品被夾時，芯片內部就會接收到變化信號，車窗電機會自動采取反轉動作，使車窗下降一段距離，從而確保乘員的安全，避免夾傷事故的發(fā)生。 新款電路不單有防夾功能，而且當有人離車熄火后，車窗會自動關閉，保證了駕駛員不會因為疏忽，忘記關窗而造成損失。所以介紹了幾種車窗自動關閉器，人們應該以實際的需要相應作出選擇。在最后，總結了電動車窗電路的特點，并對以后電動車窗的控制電路作出展望。 關鍵詞：電動車窗，控制電路，芯片，TLC2543，防夾功能
Abstract This article first briefly Summarizes the development of power windows in the domestic foreign, with electric windows replaced the traditional hand-type windows, then introduced the older models of the control circuit, leads to the security problems of easily be caught and the hidden dangers of easily be stolen, should be replaced by another new circuit, to achieve the people's comfort and safety expectations. The new power window control circuit, compared with the old circuit, not only the continuation of its simple principle, but also proposed the use of advanced chip technology to control the window, and according to the actual requirements of the chip,select the TLC2543 as a part of the MICU . Resolve the principle of the window control circuit after adding chip in detail, to achieve more useful function as the anti-pinch to people and cars. At the same time, the car is set in hardware and software, by analyzing the changes in the internal chip to detect the operation state of the window, that is when items are caught, the chip will receive internal changes in the signal, power windows will automatically reverse, then take action to fall short of the windows to ensure the safety of the crew, to avoid crushing in the accident. The new circuit is not only have the anti-pinch function, and when people turn off from the car, the windows will automatically shut down to ensure that the driver forgot to lock the window because of negligence resulting in the loss will not happen. So introduced several windows automatically close device, it should be based on actual need to make a choice accordingly. In the end, summed up the characteristics of the power windows circuit, and on the prospects for control circuit of power windows for future.
