Description

说明书 车用昼行灯的控制装置及控制方法
【技术领域】
本发明涉及一种电力控制的技术领域， 特别是应用在汽车昼行灯的点亮或 关闭的自动控制装置及控制方法。
【背景技术】
为了增加日间行车时的可见度， 以及有效减少交通事故的发生机率， 欧盟 法规 (ECE R87 )已要求所有车辆的新车， 包括如轿车、 货车及大型车辆， 均需安 装专属的昼行灯 (Dayt ime Running Light , DRL)昼行灯的设置位置在车的前方， 相关法规要求当白天时汽车引擎发动的情况下， 必须点亮昼行灯， 其目的在于 警示路上行人于白天时注意引擎运转中的车辆。 实务上要如何辨识引擎运转来 点亮昼行灯， 有以侦测汽车电池上的电压变化来进行判定， 因为汽车发动后， 引擎的运转必会带动发电机的运转发电， 而对电池充电， 因此可由此反向由电 池电压变化推定弓 I擎的运转与否。
请参阅图 1， 图中显示一般电瓶的电压波形， 在未动作时的初始电压 VI， 且启动发电机时， 会产生电压陷落现象而使电压降至 V2; 随后电压逐渐上升至 工作电压 V3 , 并且形成有运转涟波 Q。 其中 V3〉V1〉V2。
请参阅图 2， 图中显示另一电瓶的电压波形， 其未动作时的初始电压 VI， 启动发电机后电压逐渐上升至工作电压 V3 , 进而形成运转涟波 Q。
造成以上的电压波形不同的原因包含车种形式或车辆设计不同， 以及外在 环境不同等因素。
中国台湾专利 M397337揭示一种关于昼行灯的电控装置。 该电控装置与昼 行灯及车用电子设备耦接， 以控制昼行灯及车用电子设备闭启或关闭。 电控装 置可侦测汽车电池的输出电压， 当输出电压相当于引擎的启动电压， 则输出一 重置讯号以重置一引擎运转判断电路（涟波侦测电路）， 并当汽车电池的电源讯 号上存在一个运转涟波时， 产生一开启电力讯号来开启车用电子设备， 并侦测 汽车的车灯是否被开启； 在车灯未被开启时自动开启昼行灯。 由于该专利技术在硬件上设定一个固定的参考电压， 所以必须在有产生电 压陷落状态下 (如图 1的 V2) , 该专利前案的设计才能产生一重置讯号以启动涟 波侦测电路； 换言之， 若汽车启动无产生电压陷落的情形下 (例如图 2所示）， 该专利揭露的启动昼行灯的方法可能无法正确运作， 因此也就无法满足各类形 式车辆的需求。
又当引擎熄火时， 虽然引擎运转涟波可能变小或消失， 但电池上的电压并 不一定会等于第一电压， 该电压可能会高于第一电压， 致使昼行灯无法进行关 闭。
【发明内容】
本发明的目的在于提供一种车用昼行灯的控制装置及控制方法， 其具有能 够提供精确判断出汽车是否发动以及发电机是否运转的功效； 而且可以将模拟 与数字与运算集于专用集成电路。
本发明所揭示之车用昼行灯的控制装置， 是包含一取样模组与一控制器， 其中取样模组电性连接汽车的电瓶， 并且对电瓶的电压连续取样， 以获得复数 个取样电压； 控制器则电性连接取样模组， 其具有一处理单元电性连接一记忆 体及一输入 /输出单元； 其中取样模组所取得之各取样电压被连续记录于控制 器的记忆体， 并由处理单元加以计算与分析取样电压的连续性变化， 并精确判 断出汽车是否发动以及发电机是否运转。
再者， 本发明所揭示一种车用昼行灯的控制方法， 是对电瓶的电压波形连 续取样， 并获得复数取样电压数据资料； 再将取样电压资料及其构成之波形信 息连续地记录于控制器的记忆体； 随之利用控制器的处理单元对波形连续性变 化进行分析与计算； 最后由波形连续性变化之分析与计算结果来判断汽车是否 启动； 当汽车处在启动状态， 且无外部辅助输入信号， 例如主灯或位置灯未开 启时， 无信号输入， 则可自动开启昼行灯； 并持续对电瓶的电压波形连续取样 及记录。

【具体实施方式】
请参阅图 3， 本发明所揭示之控制装置包含一取样模组（10)及一控制器 (20), 且取样模组（10)电性连接控制器（ 20 )。
取样模组（10)是电性连接电瓶（32)与发电机（34)。 取样模组（10)具有一取 样放大器（12)及与其搭配的电子元件（14)， 如电阻、 电容或电感等等； 控制器 (20)电性连接一昼行灯驱动电路（36)， 且一昼行灯（38)电性连接昼行灯驱动电 路（36)。
所述的取样模组（10)是一种电压取样元件， 其可以连续的对电瓶 (32)的电 压波形进行取样， 特别是以模拟电路的方式进行精确的取样。 值得注意的是， 在取样模组（10)内没有预先设定固定数值的参考值， 因此每一次的取样电压直 接进入模拟 I数字转换器 (ADC)(40)转换成数字数据借着连续的电压取样数据 形成一个电压波形信息。 由取样电压所产生的电压波形信息， 其电压数据的变 化趋势与电瓶电压的变化趋势相当。
控制器（20)具有一处理单元（22)， 且处理单元（22)电性连接一记忆体（24) 及一输入 /输出单元（26); 其中输入 /输出单元 (26)系电性连接昼行灯驱动电 路（36)。
取样模组（10)对电瓶（32)所取得的取样电压是经过模拟 I数字转换器 (ADC)(40)转换成数字数据后被记录在记忆体（24)， 并可由处理单元（22)进行计 算与分析， 以获得电压的连续性变化。
请参阅图 4， 利用本发明所揭示之装置控制昼行灯的方法包含以下步骤： 首先进入系统开机设定， 并且依据步骤 S50所示， 系统开始读取输出与辅 助信号 (外部辅助输入信号）， 并且加以储存。
步骤 S52揭示取样步骤， 其利用取样模组对电瓶的电压进行连续取样， 并 据此获得复数取样电压。 得注意的是， 即便是在发电机已启动的状态下， 取样 动作仍持续进行；
步骤 S54揭示连续记录步骤， 是将连续取得之取样电压数据记录于控制器 的记忆体； 此时可以形成一个与电瓶实际输出电压之波形相当之取样电压波形； 步骤 S56揭示分析计算步骤， 其利用控制器的处理单元对记忆体中的电压 波形的数据变化进行分析与计算；
步骤 S58揭示一判断步骤， 其由波形数据连续性变化之分析与计算结果进 一步判断汽车引擎是否启动或是停止， 并且记录该状态； 例如分析由取样电压 所构成之电压波形数据， 若为电压呈现逐渐上升的趋势且电压值大于初始电压 则可判断为发电机 I行车启动；
另外， 在电压呈现逐渐上升的趋势且电压值大于初始电压的条件下， 更可 侦测到稳定的涟波， 且据此判断为发电机 /行车启动。
步骤 S62揭示一综合判断步骤， 其是将汽车引擎运转或停止的状态、 外部 辅助输入信号的状态及目前控制信号输出的状态做综合性的判断， 并据以决定 是否点亮或关闭昼行灯， 或是控制昼行灯成为低亮度点亮状态以作为位置灯。
例如在汽车启动的状态下， 且无外部辅助输入信号时， 自动开启昼行灯， 反之， 若有外部辅助信号输入时， 则不允许昼行灯点亮， 此时输出至昼行灯驱 动电路可为关闭状态或是输出控制信号使该驱动电路以低功率低亮度之位置灯 模式点亮昼行灯作为位置灯功能； 且在汽车启动的情况下， 处理单元仍不断读 入取样电压资料， 并计算电瓶的平均工作电压。
在汽车未启动的状态下， 也可以持续对电瓶的电压波形连续取样及记录。 在昼行灯点亮的情况下， 侦测到外部辅助输入有输入信号， 此时将昼行灯 关闭或改以低亮度位置灯模式点亮， 又随后在该外部辅助输入信号消失后， 重 新点亮昼行灯或将亮度由位置灯调回至昼行灯亮度。
另外， 引擎或发电机停止动作时， 电压涟波可能变小或消失， 取样电压 所得到的电压值可能等于或小于电瓶的初始电压， 故昼行灯可以立即关闭。 再另外， 引擎或发电机停止动作时， 电压涟波可能变小或是消失但直流电 压仍等于或高于初始电压， 此时相邻的取样电压所得到的电压波形呈现下降的 趋势， 且电压可高于初始电压， 则可判断引擎或发电机已关闭， 进而昼行灯可 以立即关闭。
根据步骤 S50至步骤 S62所揭示的内容， 其取样电压波形可以是图 5所示， 或图 6所示。 图中的每一个点 P1至 Pn均为取样点。
是以本发明不以硬件的比较器及预设的固定参考电压来做比对判断的依 据， 故可消除因预设比较值以及硬件零件上的零件误差造成无法取得整体波形 变化数据的缺点。
再者取样电压数据被连续记录于记忆体内， 且同时被计算以分析波形的变 化； 例如取样电压所构成之电压波形成上升趋势且电压值大于初始电压并且可 侦测到稳定的涟波， 则可判断为引擎或发电机为启动状态； 或取样电压涟波变 小甚至为零且电压波形呈现下降趋势， 可判定引擎或发电机已关闭， 故可精确 地判断出汽车是否发动以及发电机是否运转， 以确实的控制昼行灯的明灭。
是以本发明利用电压波形的单位时间的变化来判定汽车是否发动以及发电 机是否运转。
甚至于是不同的电压输出波形，例如图 1及图 2的波形或相类同变化， 利用 本发明的方法仍可准确的判断发电机或引擎已启动或关闭。
其次， 即使汽车引擎未运转或发电机未发动， 以及引擎或发电机已运转的 情况下， 取样模块仍持续进行取样， 且处理单元仍不断地读入取样电压的数据， 并且转换成数据储存后加以分析目前电瓶使用的平均工作电压为多少， 进而藉 此进一步的修正各个工作模式的电压范围与趋势， 而不会仅以一个固定值去执 行工作， 故即便电瓶老化或是气候造成电瓶变化， 也不致影响本发明的使用。
再者本发明可进一步采用整合各装置形成一颗集成电路（ I C )的设计， 且 该 I C具有休眠模式， 可在本发明闲置或待机没运作时， 使电力降到极微小的 消耗量； 尤其是在汽车引擎熄火后， 电力的消耗必需降到极微， 才不会在汽车 停一段时间后把电池电力耗尽以致无法正常启动。
