Description

一种乘用车后尾灯律动灯光控制系统及控制方法 技术领域
本发明属于智能化汽车技术领域，具体涉及一种乘用车后尾灯律动灯光控制系统，还涉及一种乘用车后尾灯律动灯光控制方法。
背景技术
近些年，随着中国汽车工业制造水平的提高，国内消费者购买力的提升以及汽车价格不断下探，国内汽车普及水平得到持续提升，中国汽车市场得到快速发展。随着物质消费水平的提升，消费者不再仅仅满足于产品的基本使用功能，对产品的价值和情感诉求越来越强烈，对于汽车产品也是如此。后尾灯作为汽车外饰造型的重要组成部分，直观的体现出了购车者的形象地位与个人价值，用户也越来越想通过汽车来展示自己的个性，因此，众多汽车制造商也愈加重视人们对车灯的看法以及态度。
传统乘用车后尾灯往往用于简单地实现后转向灯、后位置灯及制动灯等一些常见的法规功能，同时灯具内部控制电路只能单一控制某个功能的LED光源同时亮或灭，点亮效果比较简单；并且用户在解锁或闭锁时，也常常仅通过转向灯闪烁来提示用户车辆位置及解闭锁状态，用户感受的汽车只是一个无生命意义的产品。
奔腾品牌在市场竞争中既要面对合资车厂的产品向下打压，同时又面对同级自主车厂的激烈竞争，如何利用现有产品及技术进行技术扩展创新，既能控 制成本，又能增强客户感知，来提升品牌的知名度，是车灯技术发展的一个重要课题。
随着灯具技术不断的发展创新以及LED光源的大量应用，灯具内部控制电路对于LED光源的控制有更大的灵活性及多样性，既可以打破常规只能同时亮或灭的点亮效果，也可以为用户解锁及闭锁时提供酷炫的律动效果带来便利性。。
发明内容
本发明的目的就在于提供一种乘用车后尾灯律动灯光控制系统，还提供一种乘用车后尾灯律动灯光控制方法，以解决用户在解锁或闭锁时，后尾灯分别实现不同的律动效果，提升整车的用户体验的问题。
本发明的目的是通过以下技术方案实现的：
一种乘用车后尾灯律动灯光控制方法，包括以下步骤：
A、后尾灯律动灯光控制
A1、当用户在使用车辆解锁时或离开车辆闭锁时由BCM驱动后转向灯点亮，提示车辆的位置或者提示车辆完成锁车；
A2、BCM依据后转向灯点亮提示，向后位置灯供电，并发出解锁律动信号或闭锁律动信号；
A3、后尾灯内部控制器进行唤醒及等待，待接收到BCM发送的律动信号后进行检测并识别，通过占空比区分，解锁占空比为30％，闭锁占空比为70％；
B、解锁律动
BCM驱动后转向灯进行时序点亮，后位置灯按照预先设定的点亮形式、点亮顺序、点亮时间分别进行解锁律动动作，后位置灯律动后，全部保持常亮， 然后再进行逐渐熄灭；

实施例2
本发明提供一种乘用车解闭锁时后尾灯律动灯光控制方法，包括后尾灯律动灯光控制、解锁律动动作和闭锁律动动作三个步骤。
1、后尾灯律动灯光控制
如图2所示，为后尾灯律动灯光控制方法流程图。律动灯光控制分为BCM动作和尾灯动作两部分。
(1)BCM动作
BCM动作分为转向提示、BCM供电、解锁律动信号、闭锁律动信号、解锁律动关闭请求等五部分动作。
①转向提示：当用户在解锁时或闭锁时，BCM驱动后转向灯3进行点亮，提示车辆的位置或者提示车辆完成锁车。这里设定，解锁时，BCM驱动后转向灯3点亮2次，每次周期800ms，共1600ms。其中，每个周期800ms分为400ms供电，400ms下电。闭锁时，后转向灯3点亮1次，周期800ms，同样分为400ms供电，400ms下电。
②BCM供电：按照解锁及闭锁的律动动作所参与的功能，这里设定，BCM给后位置灯4供电。解锁时，供电起点为后转向灯3点亮提示2次后的上电点B，下电为尾灯完成律动后300ms。闭锁时，供电起点为后转向灯3点亮提示1次后的上电点A，下电为尾灯完成律动后300ms。
③解锁律动信号：由BCM输出给灯。当后转向灯3点亮提示2次后及BCM给后位置灯4供电40ms后BCM立即发出解锁律动信号，为连续5个周期10ms的脉冲，低有效。为了节省整车线束回路，解锁律动信号与闭锁律动信号通过同一根信号线来实现。为了便于区分是解锁律动信号、还是闭锁律动信号，这里通过占空比来区分，解锁占空比为30％，闭锁占空比为70％。
④闭锁律动信号：由BCM输出给灯。当后转向灯3点亮提示1次后及BCM给后位置灯4供电40ms后BCM立即发出闭锁律动信号，为连续5个周期10ms 的脉冲，低有效。为了节省整车线束回路，闭锁律动信号与解锁律动信号通过同一根信号线来实现。为了便于区分是解锁律动信号、还是闭锁律动信号，这里通过占空比来区分，解锁占空比为30％，闭锁占空比为70％。
⑤解锁律动关闭请求：由BCM输出给灯。解锁律动过程中，如果打开任一车门，则BCM延时2s(考虑从打开车门到坐在座位上的时间)后发出解锁律动关闭请求，60ms低有效脉冲。
(2)尾灯动作
当后转向灯3点亮提示2次或者1次后，BCM给后位置灯4供电，40ms后发出解锁律动信号或者闭锁律动信号，期间后尾灯内部控制器进行唤醒及等待，待接收到律动信号后进行检测识别是解锁还是闭锁律动信号，然后按照预先设定的律动动作进行点亮，律动4s，常亮2s，渐灭4s。为了不受律动信号线上的杂波信号干扰而误触发律动，这里设定，对律动信号线上的信号滤波进行加强，限制执行律动动作的条件。不仅计算占空比即解锁25％-35％、闭锁65％-75％，还计算律动信号线上PWM的频率，频率必须满足设定的范围即80Hz-120Hz才认为是有效信号从而计算占空比，而相同的占空比连续出现两次才识别为有效的占空比。经过以上滤波之后的信号才进行律动判定，当解锁律动过程中接收到解锁律动关闭请求后50ms停止律动。
2、解锁律动动作：
如图3所示，为解锁律动动作示意图。一个完整的解锁律动，分为4个动作：
①后转向灯3提示：如图3中a所示，左、右两侧的后转向灯3，均从车内向车外进行时序点亮，即下一组点亮后，上一组保持点亮，2颗LED为一组， 单侧共12组。解锁时，BCM驱动后转向灯3时序点亮2次，每次周期800ms，共1600ms。其中，每个周期800ms分为400ms供电，400ms下电。对应后转向灯3为200ms时序点亮，200ms常亮，400ms熄灭。
②律动：如图3中b-d所示，后位置灯4按照预先设定的点亮形式、点亮顺序、点亮时间分别进行解锁律动动作，共4s，具体如下：
b：上方的后位置灯4从车内向车外滚动点亮，即下一组点亮后，上一组熄灭，3颗LED为一组，不足3颗时也算作一组，单侧共20组，点亮效果为均匀面发光效果，滚动点亮时长1.6s。
c：下方的后位置灯4从车外向车内滚动点亮，3颗LED为一组，不足3颗时也算作一组，单侧共11组，点亮效果为均匀面发光效果，滚动点亮时长0.8s。
d：上方的后位置灯4与下方的后位置灯4同时从车内向车外时序点亮，时序点亮时长1.6s。
③常亮：后位置灯4律动后，全部保持常亮，共2s。
④渐灭：后位置灯4保持常亮2s后，进行逐渐熄灭，共4s。
3、闭锁律动动作
如图4所示，为闭锁律动动作示意图。一个完整的闭锁律动，分为4个动作：
①后转向灯3提示：如图4中a′所示，左、右两侧的后转向灯3，均从车内向车外进行时序点亮，即下一组点亮后，上一组保持点亮，2颗LED为一组，单侧共12组。闭锁时，BCM驱动后转向灯3时序点亮1次，周期800ms，同样分为400ms供电，400ms下电。对应后转向灯3为200ms时序点亮，200ms常亮，400ms熄灭。
②律动：如图4中b′-d′所示，后位置灯4按照预先设定的点亮形式、点亮顺序、点亮时间分别进行闭锁律动动作，共4s，具体如下：
b′：下方的后位置灯4从车内向车外滚动点亮，即下一组点亮后，上一组熄灭，3颗LED为一组，不足3颗时也算作一组，单侧共11组，点亮效果为均匀面发光效果，滚动点亮时长0.8s。
c′：上方的后位置灯4从车外向车内滚动点亮，3颗LED为一组，不足3颗时也算作一组，单侧共20组，点亮效果为均匀面发光效果，滚动点亮时长1.6s。
d′：上方的后位置灯4与下方的后位置灯4同时从车外向车内时序点亮，时序点亮时长1.6s。
③常亮：后位置灯4律动后，全部保持常亮，共2s。
④渐灭：后位置灯4保持常亮2s后，进行逐渐熄灭，共4s。
通过以上所述，在用户解锁车辆或闭锁时，后尾灯中的后转向灯3、后位置灯4会按照预先设定的点亮顺序、点亮时间、点亮形式分别进行律动点亮，增强“人车互动”的客户体验，彰显车辆科技感及仪式感。
注意，上述仅为本发明的较佳实施例及所运用技术原理。本领域技术人员会理解，本发明不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。因此，虽然通过以上实施例对本发明进行了较为详细的说明，但是本发明不仅仅限于以上实施例，在不脱离本发明构思的情况下，还可以包括更多其他等效实施例，而本发明的范围由所附的权利要求范围决定。
