Description

夜间驾驶车辆速度限制
技术领域
本发明涉及在某些情况下限制由人类驾驶的车辆的速度，并且更具体地涉及在夜间驾驶或其他不利驾驶条件期间的速度限制。
背景技术
当第一响应者(诸如警察和救护车驾驶员)对紧急情况作出响应时，由于情况的紧急性，他们经常以高速率行驶。这些类型的紧急情况可能在白天或夜晚、良好的天气条件或恶劣条件下出现。虽然这些第一响应者通常在高速车辆操作的驾驶技术方面得到训练，但是当以高速行驶时，仍然有较少的时间对道路上的情况作出反应。这在夜间和恶劣天气条件下尤其如此，其中由于可见度降低，直到很迟以后才可能注意到车辆前方的物体；并且另外，由于潮湿的路况，车辆的停止距离可能更长。
发明内容
一个实施例设想了一种操作车辆的方法，所述方法包括：确定车辆速度是否由驾驶员控制；如果所述车辆速度由驾驶员控制，则确定所述车辆是否在夜间条件期间操作；并且如果所述车辆在夜间条件期间操作，则激活夜间驾驶模式，所述夜间驾驶模式在不考虑道路速度限制的情况下限制所述车辆的最大速度。
一个实施例设想了一种操作车辆的方法，所述方法包括：(a)确定车辆速度是否由驾驶员控制；(b)如果所述车辆速度由驾驶员控制，则通过确定光传感器是否检测到环境光低于预定水平来确定所述车辆是否在夜间条件期间操作，并且如果是，则采用全球定位系统和远程信息处理系统来确认所述车辆在夜间条件期间操作；(c)如果所述光传感器检测到夜间条件，但是所述全球定位系统和所述远程信息处理系统未确认所述车辆在夜间条件期间操作，则确定所述车辆是否在恶劣天气期间操作；(d)如果在步骤(c)中确定所述车辆在恶劣天气期间操作，则激活夜间驾驶模式，所述夜间驾驶模式在不考虑道路速度限制的情况下限制所述车辆的最大速度；以及(e)如果所述光传感器检测到夜间条件并且所述全球定位系统和所述远程信息处理系统确认所述车辆在夜间条件期间操作，则激活所述夜间驾驶模式。
一个实施例的优点在于，可以在驾驶员在不利条件下驾驶时为车辆设定最大车辆速度。此类状况可以包括例如夜间驾驶、恶劣天气驾驶以及在需要额外安全性的区域附近驾驶。另外，对于需要高于特定设定最大值的最大车辆速度的驾驶员(诸如第一响应者)，超驰可以允许更高的车辆速度。另外，除了在此类不利条件下设定最大车辆速度之外，还可以调整转向控制、制动辅助和驾驶动力学以考虑驾驶员正在驾驶车辆所处的不利条件。
附图说明
图1是车辆和可能与所述车辆的驾驶相关的远程对象的示意图。
图2是示出操作车辆的方法的流程图。
具体实施方式
图1示出了道路22上的车辆20，所述道路22可以在行人流量大的区域24周围的区域(诸如医院、学校或公园)附近。车辆20可以具有远程信息处理系统26，所述远程信息处理系统26能够与远程位置30无线通信28并从远程位置30获得信息。远程位置30可以包括警察派出所和与互联网的通信。
车辆20是由驾驶员32操作的车辆。驾驶员32可以是第一响应者，诸如警察、救护人员或其他此类紧急响应人员。当车辆20由驾驶员32操作时，车辆20行驶的速度通常由驾驶员32确定。因此，虽然车辆20可以具有巡航控制或其他类型的自主车辆控制功能，但是本文讨论的夜间驾驶模式涉及驾驶员手动地控制车辆20的速度时的时段。
车辆20可以包括典型的车辆系统，诸如仪表组34；车辆点火系统36，其包括用于起动车辆20的方式，诸如像钥匙、钥匙扣或无线蜂窝装置；挡风玻璃刮水器38；制动系统40；推进系统42；和转向系统44。车辆20还可以包括诸如道路摩擦估计系统50、驾驶动力学系统52、内部和外部温度感测系统54以及环境光感测系统56的系统。车辆系统和部件可以与一个或多个中央处理单元46通信并通过其进行控制。
除了远程信息处理系统26之外，车辆20还可以包括其他专用系统，诸如全球定位系统(GPS)48；以及障碍物检测系统58，诸如雷达或激光雷达系统。上述车辆系统通常是本领域技术人员公知的，因此在本文将不再进一步讨论。
图2示出了与用于操作图1的车辆20的方法相关的流程图。在操作车辆20时，例程前进以确定驾驶员32是否正在手动地控制车辆速度，步骤70。如果否，则例程继续监测。
如果是，则环境光感测系统确定车辆操作是否发生在夜间条件期间，步骤72。这可以采用一个或多个中央处理单元46确定环境光传感器是否感测到光水平低于预定光阈值的形式。如果否，则例程继续监测。如果是，则GPS 48和远程信息处理系统26确认车辆20在夜间条件期间操作，步骤74。这可以采用GPS 48和远程信息处理系统26检测车辆位置并与远程位置30(诸如互联网)通信的形式，以确认当日该时间对于该位置和当年时间而言在日落和日出之间。该确认步骤有助于消除对夜间驾驶的错误检测。
如果未确认为夜间条件，则可以确定车辆20是否在恶劣天气下操作，步骤76。这可以采取当例如挡风玻璃刮水器38开启、环境温度低于预定阈值或者道路摩擦的估计值较低时推断恶劣天气条件的形式。而且，这可以采取采用GPS 48和远程信息处理系统26来获得天气条件的形式。如果不是恶劣天气条件，则例程继续监测。如果是，则一个或多个中央处理单元46将车辆20的操作改变为夜间驾驶模式，步骤78。
如本文所使用的术语夜间驾驶模式限制对于车辆20所允许的最大速度，其中夜间驾驶模式的这个最大速度不考虑车辆20正在行驶所在的各种道路22上的各种速度限制。因此，无论驾驶员踩下加速踏板多深，驾驶员32都不能超过该速度。这可以独立于哪个人类驾驶员当前正在操作车辆。因此，其中处理器以特定道路的速度限制来跟踪和操作车辆的自主车辆操作不是夜间驾驶模式。
另外，当车辆20处于夜间驾驶模式时，可以在仪表组34上激活指示器以向驾驶员32发出夜间驾驶模式是激活的警报。夜间驾驶模式还可以将转向系统44的操作、制动系统40的增压辅助和驾驶动力学系统52的车辆动力学改变为更保守的设置，以考虑夜间驾驶的可见性降低。
如果在步骤74中确认夜间驾驶，则一个或多个中央处理单元46将车辆20的操作改变为夜间驾驶模式，步骤78，其中车辆操作改变恰如以上所讨论。
当以夜间驾驶模式操作时，步骤78，驾驶员32可以请求超驰车辆20在该模式下设定的速度和其他限制，步骤80。如果否，则车辆继续以夜间驾驶模式操作，同时监测变化的车辆状况。如果是，则可以通过GPS 48和远程信息处理系统26发送请求以请求超驰夜间驾驶模式。如果驾驶员32是执法人员，则该超驰请求可以被发送到例如远程位置30，诸如警察局。例如，可以通过驾驶员32激活车辆20上的应急灯和警报器，然后按下仪表组34上或转向系统44的方向盘上的按钮来指示所述请求。
然后，可以确定是否批准超驰，步骤82。此超驰批准可以来自例如远程位置30。如果未被批准，则车辆20保持在夜间驾驶模式。如果超驰被批准，则可以确定车辆20是否在地理围栏区域内，步骤84。地理围栏区域可以是例如具有行人流量大的位置周围的区域24(诸如学校、医院、公园等)。车辆20的当前位置是否在地理围栏区域内可以例如通过经由GPS48和远程信息处理系统26获得数据来确定。
如果车辆20在地理围栏区域内，则车辆20可以继续以夜间驾驶模式操作，同时监测变化的车辆状况。如果否，则一个或多个中央处理单元46可以停用夜间驾驶模式，步骤86。在夜间驾驶模式被停用的情况下，驾驶员32可以再次以高于夜间驾驶模式车辆速度限制的更高速度操作车辆。
虽然已经详细描述了本发明的某些实施例，但是熟悉本发明所涉及领域的技术人员将认识到用于实践由所附权利要求限定的本发明的各种替代设计和实施例。
在本发明的一个方面，夜间驾驶模式的激活还改变驾驶动力学系统的操作。
根据本发明，一种操作车辆的方法包括：确定车辆速度是否由驾驶员控制；如果车辆速度由驾驶员控制，则通过确定光传感器是否检测到环境光低于预定水平来确定所述车辆是否在夜间条件期间操作，并且如果是，则采用全球定位系统和远程信息处理系统来确认所述车辆在夜间条件期间操作；如果所述光传感器检测到夜间条件，但是所述全球定位系统和所述远程信息处理系统未确认所述车辆在夜间条件期间操作，则确定所述车辆是否在恶劣天气期间操作；如果确定所述车辆在恶劣天气期间操作，则激活夜间驾驶模式，所述夜间驾驶模式在不考虑道路速度限制的情况下限制所述车辆的最大速度；以及如果所述光传感器检测到夜间条件并且所述全球定位系统和所述远程信息处理系统确认所述车辆在夜间条件期间操作，则激活所述夜间驾驶模式。
在本发明的一个方面，确定车辆是否在恶劣天气期间操作包括检测到挡风玻璃刮水器开启。
在本发明的一个方面，确定车辆是否在恶劣天气期间操作包括估计车辆的道路摩擦低于预定阈值。
