Description

用于控制机动车辆的自动功能的方法
技术领域
本发明涉及配备有自动驾驶员辅助功能的机动车辆的领域，该自动驾驶员辅助功能诸如巡航控制(CC)、限速器(SL)和自动驾驶系统(ACC、塞车辅助等)。更具体地，本发明涉及一种用于控制此类功能的方法。给出控制意指可能在满足一个或多个条件时停用活动功能。
背景技术
许多机车制造商提供自动驾驶员辅助功能，诸如巡航控制以及限速器，并且其可以在越来越多的车辆中找到。此类功能在驾驶员的安全性、燃料消耗和/或舒适性方面对驾驶员展现出明显的优越性。
例如，巡航控制和限速器使得能够最佳地利用燃料消耗，尤其是在长距离驾驶中，并且使得可以避免速度过高。
限速器使驾驶员能够选择他不希望超过的最大速度。如果驾驶员试图超过他已经设定的速度，则加速器踏板变得不起作用。巡航控制使驾驶员能够选择巡航速度，车辆将保持恒定的巡航速度，而驾驶员不必触碰加速器。通常，一定数量的安全设备与自动功能相关联。例如，功能不会自己生效，并且当其被激活时，对制动踏板、离合器(对于手动变速箱而言)或变速杆的动作立即停用该功能，并且使车辆返回到传统的驾驶模式。
然而，在一些现代车辆上，已经注意到，有时难以通过简单地踩下制动踏板来停用自动驾驶员辅助功能。
这尤其涉及需要一定真空水平的自动驾驶员辅助功能，例如：巡航控制(CC)、限速器(SL)以及自动驾驶系统(ACC，塞车辅助等)。
必须保证，制动踏板在驾驶期间不会变硬，从而不会妨碍功能的停用，并因此确保安全地转换到常规驾驶模式。
例如，已经注意到，在使用巡航控制/限速器的驾驶期间，制动踏板有时会变硬，这会阻止将该功能停用和恢复常规驾驶。
本发明的目的是提出一种控制已启用的驾驶员辅助功能的装置，以便当满足某个特定的条件要求停用时停用驾驶员辅助功能。
发明内容
本发明涉及一种用于控制机动车辆的自动驾驶员辅助功能的方法，该机动车辆在制动辅助系统中需要一定的真空水平，该方法包括以下步骤：
-连续地监测该制动辅助系统中的真空水平；
-如果该真空水平低于预定阈值Vt，则由控制系统停用所述的自动功能。
分析揭示出，由于诸如制动辅助系统中的泄漏之类的故障，制动辅助系统中的低真空水平可以导致硬的踏板感觉从而防止自动功能停用。
因此，监测制动辅助系统中的真空水平使得能够在真空度低于某一阈值设定的条件下检测到该系统中存在故障，从而在制动踏板变硬之前使得系统停用自动功能并将控制返回给驾驶员。
根据本发明的一个实施例，阈值是通过实验确定的。因此，通过降低制动辅助系统中的真空水平来进行测试，以查看制动踏板变硬的极限值。该阈值在极限值上设有一定的安全裕度，以使系统能够停用该功能。安全裕度例如是100毫巴。
根据本发明的一个实施例，真空水平由压力传感器监测。增加压力传感器使解决方案具有简单、廉价的优点。
有利地，当真空水平低于预定阈值时，系统发送低真空水平警告。该警告可以是可听的和/或可视的，并且通知驾驶员存在故障。
根据本发明的一个实施例，自动驾驶员辅助功能是巡航控制(CC)或限速器(SL)功能。
本发明还涉及一种机动车辆，该机动车辆包括实施上述方法的装置。
附图说明
通过参照附图1阅读以下说明将更好地理解本发明并且本发明的其他特征和优点将变得清楚，该附图展示了本发明的实施例，其中真空传感器使得可以监测制动辅助系统中的真空水平。
具体实施方式
图1示出了车辆(未示出)的制动辅助设备(制动伺服器单元)1，该设备包括经受大气压的第一腔室11和经受由发动机2施加的真空的第二腔室12，该第二腔室通过设有止回瓣阀4的管3连接到发动机。设备1还连接到控制车辆的制动系统6的主缸5。主缸可以附加地连接到电子稳定程序(ESP)7和在主缸输出处测量液压压力的传感器(PMC)。
根据本发明所展示的实施例，真空传感器被布置在制动辅助设备上并且被连接到控制系统。该真空传感器提供真空腔室12中的相对真空水平的即时测量结果，特别是当自动驾驶员辅助功能被启用时。此类功能可以是例如巡航控制(CC)、限速器(SL)或自动驾驶系统(ACC、塞车辅助等)。
如果在驾驶期间真空传感器检测到真空腔室12中的真空水平低于预定阈值，则控制系统自动地停用所讨论功能以在制动踏板变硬之前将控制返回给驾驶员。以这种方式，降低了驾驶员由于制动踏板变硬而可能不能够返回到传统驾驶模式的风险。
另外，为了给予控制系统时间以响应自动功能的停用，阈值被设置成具有一定的安全裕度，例如100毫巴。
确定阈值的可能方式之一是通过将真空腔室12中的真空水平降低到制动踏板变硬的值V1来进行实验。在此情况下，阈值Vt为V1-100毫巴。
可以以其它方式确定该值Vt，例如通过仿真。
有利的是，除了自动功能的停用之外，控制系统还发送低真空水平警告。这意味着驾驶员意识到存在诸如泄漏问题，并且可以检查他的车辆。
本发明还涉及一种车辆，该车辆包括诸如真空传感器和控制系统的装置以实施上述方法。
