Description

在电池更换期间防止自动调平
技术领域
本发明总体上涉及一种在电动车辆的电池更换期间防止自动调平的方法和相关联的计算机程序。
背景技术
在新兴的电动车辆时代，众所周知，将在加油站或车库中使用自动化系统，以在几分钟之内用全新的、充满电的电池来更换整个电池(位于汽车底部)。例如，US 9643574 B2描述了一种用于能量储存设备交换和快速充电的装置；此外，US 2017225662 A1描述了一种具有多个电池更换站的车辆电池更换系统，该多个电池更换站用于用已充电的电池包来更换电动车辆的耗尽的电池包。
即使卸下了汽车的主电池，车辆仍可能在使用可用备用电池(例如，12V小型电池)，从而使汽车的所有系统和功能都保持活动状态。然而，随着这项新技术的出现，可能会发生许多安全问题，其中之一是在电池更换期间未充分启用电子空气悬架。空气弹簧悬架能够在多种情况下(其中之一是检测到负载变化)通过升高或降低车辆来自动调平。或者，通过卸下电池，将会从该车辆上释放出相当大的重量。在这一场景下，所有空气弹簧中的压力都发生变化，并且该悬架将通过降低该车辆来调节该压力变化。但是，在卸下旧电池或放置新电池期间的任何移动都可能导致相当大的损坏。
出于这个原因，需要在电池更换期间防止自动调平，并且仅在检查了这种操作的安全性之后才允许开始自动调平。
发明内容
因此，本发明的主要目的是在电池更换期间实现操作安全。
根据本发明，该目的通过独立权利要求的主题(即，一种在电池更换期间防止自动调平的方法、以及相关联的计算机程序)来实现。
进一步的有利实施例是从属权利要求的主题。
本发明的第一方面是一种在电池更换期间防止自动调平的方法，该方法用于配备有负责电池更换的第一电子控制单元以及悬架系统的第二电子控制单元的电动车辆，各个ECU通过内部总线系统进行通信，其中该方法包括以下步骤：从第一ECU向第二ECU发送有关车辆已准备好执行电池更换的信息；一旦第二ECU接收到所述信息，就向悬架系统触发调平禁止标志并且将其停用；一旦已经执行了所述停用，则设置反馈信号以通知可以开始电池更换；在电池更换期间，设置所述反馈信号以通知正在进行电池更换；在完成电池更换后，向第二ECU通知已成功完成电池更换，并且允许启用悬架。
本发明的即时和直接的优点是，除了已经安装在电动车辆上的硬件或物理部件之外，不需要附加的外部硬件或物理部件；另外，本发明可以以极低的成本实现。而且，本发明的方法具有广泛的益处，即：在有人的情况下防止了事故；车辆安全等级提高；同时保护了自动电池更换系统。
本发明的第二方面是一种计算机程序，该计算机程序将上述在电池更换期间防止自动调平的方法作为代码行集成。
使用这样的计算机程序的优点在于实现的自动化和通用性。
本发明的其他特殊特征和优点可以从下面通过附图对有利实施例的描述中得出。
附图说明
图1展示了根据本发明的方法的实施例的流程图。
具体实施方式
现在参照图1，负责电池更换的第一ECU 100通过内部总线系统(例如，Flexray或CAN)向悬架系统的第二ECU 200通知车辆已准备好并且准备执行电池更换。一旦第二ECU200接收到该信息，其就将向整个悬架系统触发调平禁止标志，用于暂时阻止所有的调平和压力补偿。一旦执行了停用，则设置反馈信号，用于通知电池更换过程可以开始。在电池更换期间，将相应地设置反馈信号，以反映正在进行电池更换的事实。在完成电池更换后，再次相应地设置反馈信号以向第二ECU 200通知电池更换已成功完成，从而允许启用电子悬架，这将立即触发压力补偿，从而调节车辆的高度以匹配所更换的电池的负载。
防止自动调平的方法意味着将对应的代码行插入在所述电子控制单元上运行的软件程序中，以便能够根据本发明的方法来通过发送和接收所述信息和反馈信号进行通信、并且激活相应的系统以执行电池更换和/或自动调平。
尽管已经详细描述了本发明的某些实施例，但是与本发明相关的领域的技术人员将认识到用于实践如以下权利要求所限定的本发明的各种替代设计和实施例。
