Description
相关申请的交叉引用
本专利申请要求于2017年12月12日提交的题为“POWER MANAGEMENT IN ANAUTOMOTIVE VEHICLE(机动车中的电力管理)”的待决美国临时专利申请No.62/597,915的权益,该临时申请已被转让给本申请受让人并由此通过援引全部明确纳入于此。
背景技术
本公开的各方面一般涉及机动车,尤其涉及机动车电力管理。
常规机动车包括主电源,例如电池。通常,主电源在用于启动车辆(或执行任何其他电气功能)时被消耗,然后在车辆行驶之际由发动机再充电。例如,许多驾驶室特征(仪表板指示器、信息娱乐系统、车窗电动辅助、锁等)也依赖主电池供电。
如果主电源耗尽或断开连接,则车辆特征会失去供电并停止运行。例如,当更换主电源时,时钟维护功能就无法维持。一旦车辆恢复供电(例如,通过再充电或更换电池),则时钟必须重置。需要在没有主电池供电的情况下维持时钟维护功能的解决方案。
发明内容
以下概述是仅为了帮助描述本公开的各个方面而提供的综览,并且仅被提供用于解说这些方面而非对其进行限制。

具体实施方式
图1一般地解说了根据本公开的各方面的车辆100。
车辆100可以包括PPS 110(其中“PPS”是“主电源”的缩写)、PPS传感器120、IC 130(其中“IC”是集成电路的缩写)、应急数据系统140、天线150和发动机160。
PPS 110可以是例如电池。PPS 110可以供应用于点亮仪表板和前灯、操作电动车窗和电动锁、启动车辆100的发动机160等的电力。
PPS传感器120可以被配置成测量由PPS 110供应的电力并且提供指示由PPS 110供应的电量的PPS测量信号。在一些实现中,PPS传感器120可以是电压表。PPS测量信号可以由PPS传感器120生成,并且被提供给例如IC 130。
IC 130可以是例如集成电路、电源管理IC(PMIC)、片上系统(SoC)和/或其任何组件。IC 130可以被配置成从PPS传感器120接收PPS测量信号,如将在下面更详细地描述的。IC 130可以进一步包括时钟132。时钟132可以用于跟踪一天中的时间,该时间可(例如,在仪表板上)被显示给车辆100的操作者,或者用于需要定时测量的任何其他应用。在一些实现中,IC130可以包括安全处理器。在其他实现中,可以在车辆100的其他地方提供安全处理器。在任一情形中,供应给安全处理器的电力重复丢失(和/或来自时钟132的准确定时信息重复丢失)可能会导致安全处理器的故障。安全处理器可能通常对于终端用户而言是不可访问的,并且可以被配置成支持金融交易、高级内容的数字版权管理(DRM)或任何其他合适的安全执行。例如,如果最终用户购买了在一周内观看电影的权限,则安全处理器可以被配置成执行购买交易。此外,在一周到期之际,安全处理器将停用观看功能以确保尊重数字版权。如果最终用户可以访问安全处理器,则最终用户可能能够操纵安全处理器赖以执行其许多功能的时钟。安全处理器可以具有配置成存储有限的一系列电源故障的非易失性存储器(NVM),其中可以存储最后的已知时间。在电源恢复时,可以将新时间与所存储的时间进行比较以确保时间不会倒退。然而,相对于例如扩增片上NVM存储器,在本申请中描述的时钟时间维护可以是优选的。
如果由PPS 110供应的电力中断,则IC 130可能无法维持时钟132。准确的时钟可能是许多重要功能(包括安全性用途)的先决条件。在常规实现中,车辆100的操作者必须在每次电力中断(这可能是由于维护、过度使用等)之后手动设置时钟132。然而,如将在下面更详细地讨论的,即使在由PPS 110供应的电力中断的情况下,图2中描绘的方法200也可以使IC 130能够维持时钟132。
应急数据系统140可以包括调制解调器142和BPS 144(其中“BPS”是“备用电源”的缩写)。在一些实现中,应急数据系统140可以包括弹性壳体,该弹性壳体被设计成保护调制解调器142(以及应急数据系统140的其他关键组件)免受损坏,并且在紧急情况期间(例如,当汽车发生事故时)保持运行。调制解调器142可以耦合到天线150,并且如果车辆100发生事故,则调制解调器142和天线150可以用于联系应急服务并向其中继相关数据。
在一些实现中,发动机160可以是例如内燃机。由PPS 110供应的电力可被用于启动发动机160。在发动机160运转之后,由发动机160生成的电力可被用于对PPS 110和/或BPS 144充电。
在其他实现中,发动机160可以用其他电源来代替和/或增强。例如,如果车辆100是混合动力车,则车辆100可以包括多个电源(例如,电池)。如果车辆100是电动车,则发动机160可以被省略并且由多个电源(例如,电池)代替。在任一情形中,车辆100均具有为IC130、应急数据系统140和车辆100的其他组件供电的PPS 110。
图2一般地解说了一种维持时钟(例如,图1中描绘的时钟132)的方法。
在210,方法200使用由PPS 110供应的电力来维持时钟132和/或安全处理器。在210处的维持可以由例如图1中描绘的IC 130来执行。
在220,方法200测量由PPS 110供应的电力。在220处的测量可以由例如图1中描绘的PPS传感器120来执行。
在230,方法200提供指示由PPS 110供应的电量的PPS测量信号。在230处的提供可以由例如与图1中描绘的PPS传感器120类似的PPS传感器来执行。PPS测量信号可以被提供给例如IC 130。如上所述,在一些实现中,PPS传感器120可以包括电压表。电压表可以用于监视PPS 110的电压。
在240,方法200确定PPS测量信号是否下降到阈值以下。如果PPS测量信号没有下降到阈值以下(在240为‘否’),则方法200返回到210处的维持,并且方法200继续使用由PPS110供应的电力来维持时钟132。如果PPS测量信号下降到阈值以下(在240为‘是’),则方法200前进到250。
在250,方法200使用由BPS 144供应的电力来维持时钟132和/或安全处理器。从PPS 110到BPS 144的转变可以使用开关来执行。开关可以断开到PPS 110的电路径和/或闭合到BPS 144的电路径。如果PPS传感器120确定由PPS 110供应的电力已经恢复,则开关可以进行反向操作。
在由PPS 110供应的电力中断的情况下,可以执行方法200以便维持安全处理器的功能和/或避免在主电源恢复之际必需手动重置时钟132。
图3一般地解说了根据本公开的各方面的车辆300。
车辆300可以包括PPS 310、PPS传感器320、IC 330、应急数据系统340、天线350和发动机360。
PPS 310可以类似于PPS 110。相应地,PPS 310可以供应用于点亮仪表板和前灯、操作电动车窗和电动锁、启动车辆300的发动机360等的电力。
PPS传感器320在一些方面可以类似于PPS传感器120。例如,PPS传感器320可以被配置成测量PPS 110的电压。然而,PPS传感器320可以进一步被配置成感测PPS简档数据,如将在下面参照图4更详细地讨论的。
IC 330在一些方面可以类似于IC 130。IC 330可以被配置成从PPS传感器320接收PPS简档数据。IC 330可以耦合到数据库334和/或一个或多个传感器336。
数据库334可以被IC 330用于存储由PPS传感器320提供的PPS简档数据。在一些常规实现中,电源信号是相对静态的直流(“DC”)电压。然而,根据本公开的各方面,PPS简档数据可以被叠加、编码(等等)在由PPS 310生成并用于向车辆300供电的直流上。附加地或替换地,通过任何合适的方法(例如,蓝牙、蓝牙低能耗、WiFi、射频标识(“RFID”)等)将PPS简档数据从PPS 310传递到IC 330。
一个或多个传感器336可以提供传感器数据。数据库334可以被IC 330用于存储从一个或多个传感器336接收到的传感器数据。该一个或多个传感器336可以包括一个或多个温度传感器、一个或多个加速计、一个或多个事故检测器(例如,安全气囊展开传感器)和/或任何其他合适的传感器。
应急数据系统340可以类似于应急数据系统140,并且可以包括与调制解调器142类似的调制解调器342。相应地,应急数据系统340可以包括弹性壳体,该弹性壳体被设计成保护调制解调器342(以及应急数据系统340的其他关键元件)免受损坏,并且在紧急情况期间(例如,当汽车发生事故时)保持运行。调制解调器342可以耦合到天线350,并且如果车辆300发生事故,则调制解调器342和天线350可以用于联系应急服务并向其中继相关数据。
在一些实现中,PPS简档数据、传感器数据或任何其他数据可以由天线350接收并被提供给调制解调器342。根据本公开,可以从外部数据库(例如,远程服务器)、外部传感器(即,不与车辆300相关联)等获得PPS简档数据和/或传感器数据(或其部分)。
发动机360可以是例如内燃机。由PPS 310供应的电力可被用于启动发动机360。在发动机360运转之后,由发动机360生成的电力可被用于对PPS310充电。调节器362可以调节用于对PPS 310充电的电力。如下面将更详细地讨论的,调节器362可以由例如IC 130控制。
在另一实现中,发动机360可以被省略或用其他电源来增强。例如,如果车辆300是混合动力车,则车辆300可以包括多个电源(例如,电池)。如果车辆300是电动车,则发动机360可以被省略并且由多个电源(例如,电池)代替。在任一情形中,车辆300均具有为IC330、应急数据系统340和车辆300的其他组件供电的PPS 310。
图4一般地解说了一种控制电力管理的方法400。
在410,方法400从PPS 310接收配置成供应电力的PPS信号和配置成指示PPS 310的一个或多个特性的PPS简档信号。该接收可以由例如IC 330来执行。PPS简档信号可以被叠加在PPS信号上、被编码在PPS信号内或以其他方式被包括在PPS信号中。
PPS简档信号可以包括PPS简档信息,该PPS简档信息包括例如PPS 310的制造商、型号的标识符,部件号和/或序列号。附加地或替换地,PPS简档信息可以包括例如PPS使用信息,例如,自电池安装以来的时间长度、提供给车辆的电量、接收到的再充电量等。附加地或替换地,PPS简档信息可以包括例如与PPS 310相关联的一个或多个充电简档。充电简档可以指定条件和/或充电特性的任何组合。例如,充电简档可以标识对PPS 310而言最优的电压、电压变化率、充电电流或电流变化率。在一些实现中,充电简档可以随着PPS 310的温度和/或电压而变化。例如,在PPS 310较冷时第一充电电压可以是最佳的,而在PPS 310较热时(与第一充电电压不同的)第二充电电压可以是最佳的。在此情景中,可以将充电简档建模为以温度为变量的代数表达式。
在420,方法400使用由PPS信号供应的电力进行操作。420处的操作可以由例如IC330来执行。
在430,方法400基于PPS简档信号确定PPS 310的一个或多个特性。
在435,方法400可选地接收由一个或多个传感器336提供的传感器数据。返回到早先的示例,传感器数据可以包括当前温度。430处的接收可以由例如IC 330来执行。
在440,方法400基于(在430处确定的)该一个或多个特性和/或(在435处接收的)传感器数据来管理电力。返回到早先的示例,在440处的管理可以包括确定最佳充电信号(例如,最佳充电电流或其他合适的特性)并(例如,通过将对最佳值的指示提供给调节器362来)使得发动机360向PPS310提供最佳充电电流。该管理可以由例如IC 330来执行。调节器362可以接收对最佳值的指示,并且可以控制由发动机360供应给PPS 310的电力的充电电流(或其他特性)。
图5一般地解说了PPS(例如,PPS 310)的充电简档500。如上所述,充电简档500可以被包括在PPS简档数据中。充电简档500可以指示PPS 310的最大推荐电压(例如15V)、优选充电电流(例如1.3A)和触发优选充电电流变化(例如0.1A)的一个或多个触发电压(例如14V)。应当理解,充电简档将基于电池的类型和容量而变化,并且可能附加地受其他环境和因电池而异的条件的影响。
充电简档500示出了由粗实线指示的充电电流501和由粗虚线指示的PPS电压502。在初始状态510中,PPS 310具有4V的电压并且不接收充电电流。该电压可以高于或低于4V,并且将理解,在一些实现中,在图5的描述中标识的具体值可以是任何合适的值。如果例如PPS 310的电压低于阈值电压、PPS 310的电阻高于阈值电阻、或者PPS 310或其环境温度低于最小温度或高于最大温度,则IC 330可被配置成检测到错误。IC 330可以进一步被配置成基于检测到的错误来提供错误通知。
IC 330可以确定PPS 310的PPS电压502(例如,初始状态510中的电压)低于最小电压阈值(例如,14V)。该确定可以基于例如来自PPS传感器320的信号。因此,IC 330可以通过命令调节器362向PPS 310提供充电电流来执行电力管理。在一些实现中,仅当IC 330没有检测到错误时,IC 330才可以执行电力管理。
调节器362可以通过将充电电流501的电平增加到批量充电(bulk charging)电流来作出响应。可以在批量充电时段520期间将充电电流501提供给PPS 310。在批量充电时段520期间,PPS电压502可以响应于充电电流501的增加而升高。当PPS电压502达到触发电压(例如最小推荐操作电压)时,批量充电520可以结束。如果检测到错误,则批量充电520也可以结束。IC 330可以被配置成例如在PPS 310或其环境温度低于最小温度或高于最大温度、或者批量充电时段计时器已期满时检测到错误。
在批量充电时段520之后是吸收充电时段530。在吸收充电时段530期间,充电电流501的量减小,而电压基本保持恒定。在图5的示例中,在吸收充电时段530的过程中,充电电流501从1.3A下降到0.1A。如上所述,当PPS电压502达到触发电压(例如14V)时,可以触发从批量充电时段520到吸收充电时段530的转变。例如,PPS传感器320可以感测PPS电压502并将结果提供给IC 330。IC 330可以确定是否已经达到触发电压。特别地,当PPS电压502达到(例如)14V时,IC 330可以命令调节器362减小充电电流501。在图5的示例中,在吸收充电时段530期间,充电电流501下降至0.1A。
在吸收充电时段530之后是浮动充电时段540。在浮动充电时段540期间,IC 330命令调节器362将充电电流501维持在浮动充电电流(在图5的示例中为0.1A)。响应于浮动充电电流,PPS电压502上升到最大推荐电压(例如15V)。
尽管未示出,但是将理解,一旦达到最大推荐电压,则可以切断充电电流501(即,减小到0.0A)。将进一步理解,如果PPS电压502最终回落到最小电压阈值以下,则可以重复以上参照图5描述的过程。
如上所述,充电简档500可以因PPS 310的具体品牌或型号而异。此外,充电简档500可以是动态充电简档,其中最小电压阈值、批量充电电流、触发电压、浮动充电电流等的具体值响应于所感测的条件而变化。例如,如果一个或多个传感器336包括温度计,则温度(例如,电池温度、环境温度等)可以是所感测的条件。随着温度变化,最小电压阈值、批量充电电流、触发电压、浮动充电电流等中的一者或多者的具体值也可以变化。例如,如果温度降到十摄氏度以下,则最佳的批量充电电流可以增加或减少。因此,充电简档500提供关于应如何修改指定值以及应响应于特定感测条件而命令什么的指引。
