压路机械的控制方法和压路机械 技术领域
本申请涉及工程机械技术领域，具体而言，涉及一种压路机械的控制方法和一种压路机械。
发明背景
在相关技术中，压力机的启振方式通常有两种：
一种方式是，在振动轮启振时避免负载过大，使用小排量的泵，通过分动箱提升泵的流量，在节能模式下，无振动行走时手柄和发动机转速联动，当手柄推至最大转速时发动机转速达到节能模式下设定的最大转速。当振动时，发动机转速升至节能模式下最大转速，同时行驶泵的排量变化保持速度不变，至此发动机转速不再变化。
一种方式是，怠速到额定时发动机转速不变，手柄动作时发动机转速升至额定转速，当手柄回中位时发动机转速到怠速，减少了发动机高转速运行时间，降低油耗。
但是，这两种方式存在以下问题：
1)发动机负载率较大的压路机如何节能控制的问题；
2)发动机在较低转速下的振动轮启振的问题。
发明内容
本申请旨在至少解决或改善相关技术中存在的技术问题之一。
为此，本申请第一方面实施例提供了一种压路机械的控制方法。
本申请第二方面实施例提供了一种压路机械。
根据本申请第一方面实施例，本申请提出了一种压路机械的控制方法，压路机械包括发动机、行驶泵和振动泵、振动组件，行驶泵和振动泵由发动机取力，控制方法包括：响应于启动振动请求，调高发动机的转速至超出预设转速区间，并调低行驶泵的排量；以及启动振动泵；判断振动组件是否完成启振；在振动组件完成启振后，调低发动机的转速至预设转速区间内，调高行驶泵的排量，调高振动泵的排量。
本申请提出的压路机械的控制方法，应用于压路机械，压路机械包括发动机、行驶泵、振动泵和振动组件，振动泵和行驶泵由发动机驱动，振动泵用于驱动振动组件振动，行驶泵用于驱动压路机械行驶，进而在压路机械接收到启动振动请 求时，调高发动机的转速，使发动机的转速超出预设转速区间，达到一个较高的值，并调低行驶泵的排量，启动振动泵，由于发动机的转速达到了超出预设转速区间的值，进而可以带动负载较大的振动组件，进而实现发动机低转速下的振动功能的启动，最大效率的发挥发动机的性能，并在启振完成后，将发动机的转速调回至预设转速区间，调高行驶泵的排量，调高振动泵的排量，由于发动机的转速和振动泵的排量与振动组件的振动频率相关，因此，调低发动机的转速，并调高振动泵的排量，可以减小由于发动机转速的降速对振动组件振动频率的影响，保证振动频率的稳定，并且，由于发动机的转速和行驶泵的排量与压路机械的行驶速度相关，因此，在调高发动机的转速，并降低行驶泵的排量，可以减小由于发动机转速的提升对压路机械行驶速度的影响，进而便于压路机械在行驶过程中启动振动组件。
以及，发动机是在压路机械接收到启动振动请求后，调高转速，那么在发动机在压路机械接收到启动振动请求之前，可以保持一个低转速运行的状态，进而实现振动组件的在发动机低转速下启振，并且，在启振完成后，发动机的转速调低到预设转速区间内，更利于压路机械的节能环保。

在该技术方案中，在接收到启动振动请求后，将发动机的转速调高至预设转速，将行驶泵的排量调低到第一预设排量值，进而为发动机的转速和行驶泵的排量提供一个固定的点，进而更有利于控制压路机械的行驶速度，保持压路机械行驶速度的恒定，并且，对于振动组件的启振也会提供一个稳定的动力基础。
在上述任一技术方案的基础上，进一步地，还包括：检测压路机械的行驶速度，根据压路机械的行驶速度，确定发动机的转速和行驶泵的排量的第一对应关系，根据预设转速值和第一对应关系确定第一预设排量值。

本申请的附加方面和优点将在下面的描述部分中变得明显，或通过本申请的实践了解到。
附图简要说明
本申请的上述和/或附加的方面和优点从结合下面附图对实施例的描述中将变得明显和容易理解，其中：
图1示出本申请第一个实施例提供的压路机械的控制方法的流程图；
图2示出本申请第二个实施例提供的压路机械的控制方法的流程图；
图3示出本申请第三个实施例提供的压路机械的控制方法的流程图；

实施本发明的方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图5描述根据本申请一些实施例提供的压路机械的控制方法与压路机械。
实施例1：
图1示出本申请第一个实施例提供的压路机械的控制方法的流程图。
如图1所示，本申请第一个实施例提供的压路机械的控制方法的具体流程如下：
步骤102：响应于启动振动请求，调高发动机的转速至超出预设转速区间，并调低行驶泵的排量；
步骤104：启动振动泵；
步骤106：判断振动组件是否完成启振；在判断结果为是的情况下，执行步骤108，在判断结果为否的情况下，返回再次执行步骤106；
步骤108：在振动组件完成启振后，调低发动机的转速至预设转速区间内，调高行驶泵的排量，调高振动泵的排量。
在该实施例中，压路机械在行进过程中，若接收到启动振动请求，则调高发动机的转速，并调低行驶泵的排量，其中，调高发动机的转速可以为压路机械的振动组件提供更高的动能，可为大负载的振动组件提供启动的动能，进而实现发动机低转速下的振动功能的启动，最大效率的发挥发动机的性能，无需使用分动器提升发动机的传递出的转速，进而使得压路机械的结构简单，降低成本。
但是，压路机械的行驶速度是由行驶马达的流量所决定的，行驶马达由行驶泵提供液压源，行驶马达的流量可视作发动机的转速乘以行驶泵的排量，因此，发动机的转速与行驶泵的排量直接影响到压路机械的行驶速度，若单独调高发动机的转速，会导致压路机械的行驶速度的大幅度提升，进而在压路机械行进过程中启动振动功能会造成危险，所以本申请还调低行驶泵的排量，进而可以降低启动振动功能时对压路机械的行驶速度造成的影响，更利于压路机械在行驶过程中启动振动功能。
并且，在发动机完成启振后，调低发动机的转速至预设转速区间内，进而将发动机的转速调节到一个预设的转速范围内，可以降低压路机械的能耗，达到节能的目的，在此时提升行驶泵的排量，再次降低发动机的转速变化为压路机械行驶速度带来的影响。
以及，由于发动机的转速和振动泵的排量与振动组件的振动频率相关，因此，在调低发动机的转速后，并调高振动泵的排量，可以减小由于发动机转速的降速对振动组件的振动频率的影响，保证振动的稳定。
并且，本申请的控制步骤简单，效率高，且无需蓄能器，在高原等环境依然适用。
其中，上述“压路机械在行进过程中”的描述仅作为说明使用，本申请也可以在压路机械停止时行进使用。
具体地，预设转速区间可以是压路机械的经济转速区间，其中，经济转速区间是指车辆中发动机最省油时的转速区间，由于车辆结构的不同，发动机结构的不同，导致不同车辆的经济转速区间不同，例如：有的压路机械的经济转速区间在1700r/min至1900r/min，有的压路机械的经济转速区间在1300r/min至1500r/min。
实施例2：
图2示出本申请第二个实施例提供的压路机械的控制方法的流程图。

步骤206：启动振动泵；
步骤208：判断振动组件是否完成启振；在判断结果为是的情况下，执行步骤210，在判断结果为否的情况下，返回再次执行步骤208；
步骤210：在振动组件完成启振后，调低发动机的转速至预设转速区间内，调高行驶泵的排量，调高振动泵的排量。
在该实施例中，在上述实施例1的基础上，在响应于启动振动请求，调高发动机的转速至超出预设转速区间，并调低行驶泵的排量的步骤之前，控制发动机以预设转速区间的转速运行，进而保证了发动机的转速在经济转速区间，可以确保发动机在行进过程中的节能效果。
实施例3：
图3示出本申请第三个实施例提供的压路机械的控制方法的流程图。
如图3所示，本申请第三个实施例提供的压路机械的控制方法的具体流程如下：
步骤302：响应于启动振动请求，调高发动机的转速至预设转速值，并将行驶泵的排量调低到第一预设排量值；
步骤304：启动振动泵；
步骤306：判断振动组件是否完成启振；在判断结果为是的情况下，执行步骤308，在判断结果为否的情况下，返回再次执行步骤306；
步骤308：在振动组件完成启振后，调低发动机的转速至响应于启动振动请求之前的转速，调高行驶泵的排量至响应于启动振动请求之前的排量，调高振动泵的排量至第三预设排量值，使得压路机械的行驶速度恒定。
其中，预设转速值大于经济转速区间的上限值。
在该实施例中，在实施例1或实施例2的基础上，若接收到启动振动请求，则调高发动机的转速至预设转速值，并调低行驶泵的排量至第一预设排量值，其中，设定具体预设转速值与第一预设排量值，可以针对性的对压路机械的行驶速度进行调整，保持压路机械行驶速度的恒定，有利于对压路机械的控制。
同样地，针对振动泵的排量，在启振完成后，将振动泵的排量调高至第三预设排量值，进而可以根据振动组件的频率控制振动组件稳定的运行。
实施例4：
图4示出本申请第四个实施例提供的压路机械的控制方法的流程图。
如图4所示，本申请第四个实施例提供的压路机械的控制方法的具体流程如下：
步骤402：响应于启动振动请求，调高发动机的转速至预设转速值，并将行驶泵的排量调低到第一预设排量值；
步骤404：以预设频率对应的第二预设排量值，启动振动泵；
步骤406：判断振动组件的振动频率是否达到预设频率；在判断结果为是的情况下，执行步骤408，在判断结果为否的情况下，返回再次执行步骤406；
步骤408：在振动组件的频率达到预设频率后，调低发动机的转速至响应于启动振动请求之前的转速，调高行驶泵的排量至响应于启动振动请求之前的排量，调高振动泵的排量至第三预设排量值。
在该实施例中，在实施例1至实施例3中任一者的基础上，进一步地，判断振动组件是否完成启振，是通过判断振动组件的振动频率是否达到预设频率所实现的，具体地，判断振动组件的振动频率是否达到预设频率可以是，判断振动组件的振动频率是否在预设时间内连续保持预设频率。其中，预设时间可以是3秒、5秒等，进而可以准确的对压路机械进行控制。
实施例5：

当然，振动频率的设置指令也可以是本次输入的。
进一步地，针对确定的振动频率，调节振动泵的排量，为振动组件提供足够的动力。
