Abstract

一种作为配件的加速信号放大器(A)，其安装在油门踏板(B)和电子控制单元(C)的电位计之间，通过程序控制与调整来自油门踏板的信号。该放大器有助于改善汽车的加速性能，并能克服在操作失当情况下所遇到的问题。该放大器测量油门踏板的信号，计算出加速度的电位计的角度变化(角速度)，并以倍数放大来自油门踏板的信号，倍数值取决于油门踏板的电位计的角速度。放大器还包括一个具有巡航控制的功能，由一个控制开关(F)控制。

Description

加速信号的放大器---汽车的自动巡航仪
技术领域
本发明涉及一种不间断测量并转换现代汽车电子油门踏板的电位计所产生信号的***。
背景技术
近年来，装有电子油门踏板的新科技汽车的驾驶员对油门踏板反应迟滞的抱怨增多。在新型科技汽车中，加速的指令不是通过传统的线路(机械方式)来传输的，而是通过驾驶员的脚借助于电位计向ECU(电子控制单元)传输(电子油门踏板)。采用电子油门踏板的缺陷是汽车加速性能欠佳，以及操作失当时会出现问题，尤其是汽车整体的运转表现不佳。
本发明将克服采用电子油门踏板后加速性能欠佳的缺陷。
新型科技汽车的加速信号放大器的基本原理是：通过安装适当软件以数字方式放大电位计的信号，并传输给控制单元。
在放大加速信号的同时，该放大器还有另一项功能：当驾驶员需要时可按下开关使汽车保持匀速前进(自动巡航)。新型科技汽车的加速信号放大器有一个基本零件，即一个微处理器，其通过程序测量加速电位计所发出的信号，并将放大后的信号传输给ECU(电子控制单元)，以改善汽车的加速性能，并在驾驶员需要时在长途旅程中保持匀速行驶。
发明内容
本发明仅改变电子油门踏板的信号，并不改变汽车中央程序的结构。
本发明的另一个优势在于，按下汽车的控制面板上的一个开关，可关闭该装置(待命指令)。
附图说明
下图是从平面图一中选取的本发明的外观图。
图1所示的是本装置的真实外部尺寸。图2所示的是用于新型科技汽车的加速信号放大器的电路设计图---自动巡航仪。
来自加速电位计的信号经平滑处理后导入微型处理器的A/D输入端。微型处理器(图1-A)的程序主要用来测量来自油门踏板的信号，另一方面，并计算油门踏板角度的变化值(角速度)。该程序通过由油门踏板的电位计的角速度决定的算法以倍数放大信号。
具体实施方式
在微型处理器入口处的信号以及在微型处理器出口处的放大后信号在彼此之间都得到了比较。另一个算法对这些信号比较结果进行监控，并决定这些输入信号及这些信号被放大后的信号在输出装置之前能否被接受。
只要本装置安装在加速电位计(图1-B)和电子控制单元(ECU)(图1-C)之间，当驾驶员需要时，该装置可实现自动巡航。
当汽车的达到一定的速度，如，每小时80公里，如果驾驶员按下自动巡航仪的开关(图1-F)，程序就会读取指令，并接下来的五秒种内等待驾驶员在将脚抬离油门踏板(确认自动巡航仪的指令)。
如果程序确认两种装置的状态(开关和踏板)，就会启动自动巡航的操作。
此时微型处理器停止放大电子油门踏板的信号，仅读取引擎的RPM，增加或减少发往ECU的指令，从而在无需驾驶员作用于油门踏板的情况下，使引擎的RPM与汽车的速度都处于稳定状态。
来自于喷油器的脉冲(图1-D)用来计算自动巡航过程中引擎的转速度(RPM)。为终止自动巡航，可以采取下列任何一个办法：驾驶员或者踩下刹车踏板(图1-E)，或再次踩下油门踏板(图1-B)。
加速信号放大器---自动巡航仪(图1-A)，安装在油门踏板(图1-B))的电位计和电子控制单元(ECU)(图1-C)之间。
本***为单体，安装在汽车的内部，与油门踏板的连接器相连接。
本装置的设计使其能方便快捷地安装在任何模块中，无须切入汽车的电路(不影响汽车电路，如喷射***，点火***，ABS等)。
