技术领域
本公开涉及车辆巡航控制技术领域，特别涉及一种巡航控制装置、方法及方向盘。
背景技术
近年来，新能源汽车行业兴起高速巡航控制功能热潮。但是，传统巡航控制方案多是通过多功能方向盘上的四种按键，即CEUISE(主巡航开关功能键)、SET/-(巡航车速设置功能键/巡航减速功能键)、RES/+(巡航复位功能键/巡航加速功能键)、CANCEL(巡航取消功能键)来分别实现巡航开关功能、巡航车速设置功能、巡航加速功能、巡航减速功能、巡航复位功能、巡航取消功能等。但是，这一多种按键的布设方式使得驾驶员在驾驶中不易找到预期想要使用的巡航功能按键，造成不好的用户体验，并且按键数量的繁多，也加深了驾驶员误操作的风险，带来安全隐患。
另外，多个巡航按键也使得车辆进入相应巡航功能的逻辑变得复杂，举例而言，驾驶员如果想要设置巡航车速，需要先按CEUISE键以开启巡航功能，再按SET键来设置巡航车速，从而需要两次按键才能达到设置巡航车速的目的。
公开内容
有鉴于此，本公开旨在提出一种巡航控制装置，以解决传统巡航控制方案按键众多且巡航控制逻辑复杂的问题。
为达到上述目的，本公开的技术方案是这样实现的：

进一步的，所述巡航按键被配置为在被按动时产生指定电平信号，并将所述指定电平信号发送至所述控制器；并且所述控制器用于识别所述巡航按键的实时按动时间包括：根据所接收的指定电平信号的持续时间来确定所述巡航按键的实时按动时间。
进一步的，所述控制器为VCU(Vehicle Control Unit，整车控制器)。
进一步的，所述控制器用于控制所述车辆开启巡航功能并执行所述巡航设置指令包括：控制车辆巡航功能开启；获取车辆状态信息；以及在所述车辆巡航功能开启的情况下，根据所述车辆状态信息判断车辆是否符合执行相应的巡航设置指令的预设条件，若是，则控制所述车辆执行所述巡航设置指令以进入相应巡航状态；其中，所述巡航状态包括激活状态和关闭状态。
进一步的，所述巡航控制装置还包括：单个显示件，与所述控制器通信连接，并被配置为显示当前的巡航状态。
相对于现有技术，本公开所述的巡航控制装置具有以下优势：本公开所述的巡航控制装置可通过单个按键来实现传统巡航控制方案中两个或两个以上的按键的功能，明显地节省了成本，且简化了巡航控制逻辑。
本公开的另一目的在于提出一种巡航控制方法，以解决传统巡航控制方案依靠多个按键实现巡航控制且控制逻辑复杂的问题。
为达到上述目的，本公开的技术方案是这样实现的：
一种巡航控制方法，应用于上述的巡航控制装置的所述控制器，且所述巡航控制方法包括：接收所述单个巡航按键响应于用户按动操作而发送的巡航 设置指令，其中所述巡航设置指令是指默认车辆巡航功能开启后用于指示进行巡航设置的指令；以及响应于所述巡航设置指令，控制所述车辆开启巡航功能并执行所述巡航设置指令。
进一步的，所述控制所述车辆开启巡航功能并执行所述巡航设置指令包括：控制车辆巡航功能开启；获取车辆状态信息；以及在所述车辆巡航功能开启的情况下，根据所述车辆状态信息判断车辆是否符合执行相应的巡航设置指令的预设条件，若是，则控制所述车辆执行所述巡航设置指令以进入相应巡航状态；其中，所述巡航状态包括激活状态和关闭状态。
所述巡航控制方法与上述巡航控制装置相对于现有技术所具有的优势相同，在此不再赘述。
本公开的另一目的在于提出一种方向盘，以解决传统方向盘上巡航按键众多的问题。

本公开的其它特征和优点将在随后的具体实施方式部分予以详细说明。
上述说明仅是本公开技术方案的概述，为了能够更清楚了解本公开的技术手段，而可依照说明书的内容予以实施，并且为了让本公开的上述和其它目的、特征和优点能够更明显易懂，以下特举本公开的具体实施方式。
附图说明
为了更清楚地说明本公开实施例或相关技术中的技术方案，下面将对实施例或相关技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
构成本公开的一部分的附图用来提供对本公开的进一步理解，本公开的示意性实施方式及其说明用于解释本公开，并不构成对本公开的不当限定。在附图中：
图1是本公开实施例的一种巡航控制装置的功能结构示意图；
图2是本公开实施例的示例的巡航状态跳转逻辑图；以及
图3是本公开另一实施例的巡航控制方法的流程示意图；
图4示意性地示出了用于执行根据本公开的方法的计算处理设备的框图；并且
图5示意性地示出了用于保持或者携带实现根据本公开的方法的程序代码的存储单元。
具体实施例
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
需要说明的是，在不冲突的情况下，本公开中的实施方式及实施方式中的特征可以相互组合。
下面将参考附图并结合实施方式来详细说明本公开。
图1是本公开实施例的一种巡航控制装置的功能结构示意图，该巡航控制装置包括：设置在车辆的驾驶员操作区域的单个巡航按键100，且所述巡航按键100被配置为响应于用户按动操作而发送巡航设置指令；以及控制器200，与所述巡航按键100通信连接，用于接收所述巡航按键所发送的巡航设置指令，并控制所述车辆开启巡航功能并执行所述巡航设置指令。
其中，所述巡航设置指令是指默认车辆巡航功能开启后用于指示进行巡航设置的指令，其可以包括巡航车速设置指令、巡航加速指令、巡航减速指令、巡航复位指令、巡航取消指令中的任意一者或多者。
据此，可知本公开实施例的巡航控制装置跳过了车辆巡航功能开启的逻辑，而在巡航按键100被按动时，直接默认车辆巡航功能已开启，并执行按动按键产生的巡航设置指令。如此，省去了关于车辆巡航开关功能的逻辑和按键，既简化控制逻辑，又节省成本。
举例而言，对于传统巡航控制方案，移除其SET键，而通过本公开实施例的方案，使得其常规CEUISE键产生按动后，直接进入可设置巡航车速的状态。
在优选的实施例中，所述控制器200用于接收所述巡航按键所发送的巡航设置指令包括：识别所述巡航按键的实时按动时间；以及在所识别的实时按动时间大于设定的时间阈值时，确认接收所述巡航设置指令，否则拒绝接收所述巡航设置指令。
在此，设定时间阈值的目的在于避免驾驶员误碰按键而开启巡航功能，从而识别按动时间，超过时间阈值的指令才被认为是有效指令而被接收。
举例而言，假设所述时间阈值为1s，则本公开实施例的单个巡航按键100的功能可被定义如下：
1)定义按键按动时间≥1s，此时发送巡航车速设置指令，从而该巡航按键100相当于集成传统巡航控制方案的常规CEUISE键和常规SET键；
2)定义按键按动时间＜1s为驾驶员的误操作，不启动巡航功能。
在传统巡航控制方案中，驾驶员要启动常规SET键对应的巡航车速设置功能，需要先按下常规CEUISE键，车辆启动巡航功能，以等待驾驶员的进一步操作，而驾驶员再进行按下常规SET键以进入设置巡航车速的模式。与之相比，本公开实施例的巡航控制装置只需单个按键单次按动，就能同时完成车辆启动巡航功能和巡航车速设置功能，既从软件层面优化了控制器执行相应巡航指令的逻辑，又从硬件层面优化了巡航按键布局。
需说明的是，上文主要以巡航车速设置功能为例，但巡航复位功能、巡航取消功能等也可采用本公开实施例的方案来对应实现。
在优选的实施例中，所述巡航按键100被配置为在被按动时产生指定电平信号，并将所述指定电平信号发送至所述控制器200，而所述控制器200用于识别所述巡航按键100的实时按动时间则可以包括：根据所接收的指定电平信号的持续时间来确定所述巡航按键的实时按动时间。
举例而言，所述指定电平信号可以是高电平，即所述巡航按键100被配置为在按动后，按键的电平信号由低电平转换为高电平，从而所述控制200可根据高电平持续时间来确定该巡航按键100的实时按动时间。
在优选的实施例中，所述控制器可以是VCU。在其他实施例中，也可另 行配置独立的控制器。
以VCU为例，在优选的实施例中，所述控制器200控制所述车辆开启巡航功能并执行所述巡航设置指令包括：控制车辆巡航功能开启；获取车辆状态信息；以及在所述车辆巡航功能开启的情况下，根据所述车辆状态信息判断车辆是否符合执行相应的巡航设置指令的预设条件，若是，则控制所述车辆执行所述巡航设置指令以进入相应巡航状态。其中，根据所述预设条件的内容，所获取的车辆状态信息可以各不相同。
本公开实施例中，所述巡航状态包括激活状态和关闭状态，下面将通过示例来说明这两个状态之间基于预设条件的跳转。图2是本公开实施例的示例的巡航状态跳转逻辑图，其中激活状态和关闭状态分别被记为Activate和OFF，且该示例以本公开实施例中单一巡航按键集成常规SET键和常规CRUISE键的功能为例。如图2所示，该示例中的巡航状态跳转逻辑主要包括以下部分：
一、当前车辆状态满足下述第一预设条件时，车辆应激活(对应Activate状态)巡航功能。
该第一预设条件包括：
1)巡航功能处于“OFF”状态；并且
2)无系统三级及以上故障，但OBC(On Board of Charger，车载充电机)三级故障除外；并且
3)车速(仪表显示车速)在30-130km/h之间，其中30-130km/h为TBD(To Be Determination，待定义)值；并且
4)制动踏板未被踩下；并且
5)挡位处于D挡(前进挡)；并且
6)巡航控制信号状态为非“0x0：Not switch off cruise control(不关闭巡航控制)”，其中所述巡航控制信号包括CDP(Controlled Deceleration for Parking Brake，驻车减速度控制)信号、VDC(Vehicle Dynamic Control，车辆动态控制)信号、TCS(Traction Control System，牵引力控制系统)信号、HDC(Hill Descent Control，陡坡缓降控制)信号；并且
7)CDP功能未激活；并且
8)“CRUISE”键被按下。本公开实施例的“CRUISE”键对应多个功能；并且
9)EPB(Electric Parking Braking，电子驻车系统)信号、开关位置信号非“0x2：Apply(施加)”。
二、当下述第二预设条件中满足时，车辆应从“Activate”状态跳转至“OFF”状态。
所述第二预设条件包括：
1)车辆处于非Ready状态；或者
2)故障等级大于等于3级(OBC三级故障除外)；或者
3)巡航按键电压故障；或者
4)制动踏板被踩下；或者
5)切出D挡；或者
6)巡航控制信号(CDP、VDC、TCS、HDC)状态为“0x1：switch off cruise control(关闭巡航控制)”；或者
7)EPB开关位置信号为“0x2：Apply”；或者
8)“CRUISE”键被按下。
据此，本公开实施例的巡航控制装置通过单个巡航按键100实现了传统巡航控制方案中常规SET键和常规CRUISE键两者所对应的巡航状态切换。
另外，在传统巡航控制方案中，一般在仪表盘同时设置有巡航图标和巡航车速图标。对此，本公开实施例的方案出于硬件及成本考虑，在简化了关于巡航功能启动的逻辑的基础上，提出只采用一种图标的方案。具体地，再次参考图1，本公开实施例的所述巡航控制装置还可以包括：单个显示件300，与所述控制器200通信连接，并被配置为显示当前的巡航状态。
举例而言，假设本公开实施例的单个显示件300用于支持巡航图标的显示，当车辆状态满足预设的相关巡航条件后，驾驶员按动巡航按键100，车辆即进入巡航设置，同时仪表点亮巡航图标，例如以示意可以进行巡航车速设置。
据此，本公开实施例可通过单个显示件示出巡航设置状态，从而不需要另外设置巡航车速图标，降低了成本，并使得仪表显示面板因减少了巡航车速图标而具有更多空间。
图3是本公开另一实施例的巡航控制方法的流程示意图，其中该巡航控制方法应用于上述实施例的巡航控制装置的控制器200。如图3所示，所述巡航控制方法包括：
步骤S310，接收所述单个巡航按键响应于用户按动操作而发送的巡航设置指令。
其中所述巡航设置指令是指默认车辆巡航功能开启后用于指示进行巡航设置的指令。
步骤S320，响应于所述巡航设置指令，控制所述车辆开启巡航功能并执行所述巡航设置指令。
在优选的实施例中，所述步骤S320中控制所述车辆开启巡航功能并执行所述巡航设置指令可进一步包括：控制车辆巡航功能开启；获取车辆状态信息；以及在所述车辆巡航功能开启的情况下，根据所述车辆状态信息判断车辆是否符合执行相应的巡航设置指令的预设条件，若是，则控制所述车辆执行所述巡航设置指令以进入相应巡航状态。其中，所述巡航状态包括激活状态和关闭状态。
该实施例的巡航控制方法的其他实施细节及效果可参考前述关于巡航控制装置的实施例，在此则不再赘述。
本公开另一实施例还提供了一种方向盘，所述方向盘包括：方向盘本体；以及上述关于巡航控制装置的实施例中所述的单个巡航按键100，且该单个巡航按键100设置在所述方向盘本体上。
本公开实施例的方向盘通过单个巡航按键实现传统巡航控制方案多个按键的功能，便于驾驶员操作，且有利于改善方向盘布局设计。
