图1示意性示出了根据本申请实施例的一种用于搅拌车的控制方法的流程示意图。如图1所示，本申请实施例提供一种用于搅拌车的控制方法，搅拌车包括高压电池包、发动机和发电机，以该方法应用于处理器为例进行说明，该控制方法可以包括下列步骤：
步骤S101：在发动机启动的情况下，获取高压电池包的剩余电量、发动机的当前转速以及搅拌车所处的当前工作状态。
步骤S102：确定剩余电量所在的电量区间。
步骤S103：根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率。
步骤S104：控制发电机按照输出功率工作，以由发电机为高压电池包充电。
为防止搅拌筒内混凝土凝固，现有技术的搅拌车需持续启动发动机带动搅拌筒转筒，导致搅拌车的油耗较高且存在较大噪音。而纯电动搅拌车续航里程较短，难以保障作业过程中能够具有足够的电能驱动电机带动搅拌筒。为解决这一问题，在本申请实施例中，在发动机启动的情况下，处理器可以获取高压电池包的剩余电量、发动机的当前转速以及搅拌车所处的当前工作状态。当前工作状态包括行驶状态和怠速状态，不同工作状态下划分的电量区间不同。其中，行驶状态下的电量区间可分为第一电量区间、第二电量区间和第三电量区间，怠速状态下的电量区间可分为第四电量区间和第五电量区间。如此，处理器可以进一步结合当前工作状态和剩余电量确定剩余电量所在的电量区间。处理器预存储有基于发动机自身的结构特性确定的发动机转速特性曲线。发动机转速特性曲线是发动机曲轴的转速与发动机所输出的功率、扭矩及单位燃料消耗量之间的函数关系曲线。根据发动机转速特性曲线，处理器可以确定燃油消耗量较低的发动机转速区间，即预设燃油经济转速区间。随后，根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态，处理器可以确定发电机的输出功率，并通过发送功率输出指令至发电机控制器，以控制发电机按照输出功率工作，由发电机为高压电池包充电，在使高压电池包具有足够的电能提供给电机驱动器的同时，减少搅拌车的油耗，以实现节油降本的目的。
上述技术方案，在发动机启动的情况下，获取高压电池包的剩余电量、发动机的当前转速以及搅拌车所处的当前工作状态，再确定剩余电量所在的电量区间，进而根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，最后控制发电机按照输出功率工作，以由发电机为高压电池包充电。本申请实时地根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，可以在搅拌车的油耗较高且高压电池包的剩余电量充足时降低发电机的输出功率，在油耗较低且高压电池包的剩余电量不足时增加发电机的输出功率，从而减少搅拌车的油耗，降低搅拌车的使用成本。
在本申请实施例中，当前工作状态可以包括行驶状态，电量区间可以包括第一电量区间，根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，可以包括：在当前工作状态为行驶状态且电量区间为第一电量区间的情况下，判断当前转速是否处于预设燃油经济转速区间；在当前转速处于预设燃油经济转速区间的情况下，确定发电机的输出功率为第一输出功率。
具体地，在确定当前工作状态为行驶状态且电量区间为第一电量区间的情况下，处理器可以判断当前转速是否处于预设燃油经济转速区间。若当前转速处于预设燃油经济转速区间，此时油耗较低且高压电池包的剩余电量较低，发电机可以输出较大功率为高压电池包充电，因此处理器可以确定发电机的输出功率为第一输出功率，进而发送对应的功率输出指令至发电机控制器，以控制发电机按照第一输出功率工作，其中第一输出功率可以根据实际情况确定。
在本申请实施例中，该控制方法还可以包括：在当前转速不处于预设燃油经济转速区间的情况下，确定发电机的输出功率为第二输出功率，其中第二输出功率小于第一输出功率。
具体地，在确定当前工作状态为行驶状态且电量区间为第一电量区间的情况下，处理器可以判断当前转速是否处于预设燃油经济转速区间。若当前转速不处于预设燃油经济转速区间，此时油耗较高且高压电池包的剩余电量较低，为减少发电机消耗的燃油，同时确保高压电池包可以提供足够的电能至电机驱动器，处理器可以确定发电机的输出功率为第二输出功率。第二输出功率根据实际情况确定，且第二输出功率需小于第一输出功率。
在本申请实施例中，电量区间还可以包括第二电量区间，根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，可以包括：在当前工作状态为行驶状态且电量区间为第二电量区间的情况下，判断当前转速是否处于预设燃油经济转速区间；在当前转速处于预设燃油经济转速区间的情况下，确定发电机的输出功率为第二输出功率。
具体地，在确定当前工作状态为行驶状态且电量区间为第二电量区间的情况下，高压电池包的剩余电量相较于第一电量区间高。处理器可以判断当前转速是否处于预设燃油经济转速区间。若当前转速处于预设燃油经济转速区间，此时油耗较低且高压电池包的剩余电量较高，为减少发电机消耗的燃油，同时确保高压电池包可以提供足够的电能至电机驱动器，处理器可以确定发电机的输出功率为第二输出功率。
在本申请实施例中，该控制方法还可以包括：在当前转速不处于预设燃油经济转速区间的情况下，确定发电机的输出功率为第三输出功率，其中，第三输出功率小于第二输出功率。
具体地，在确定当前工作状态为行驶状态且电量区间为第二电量区间的情况下，高压电池包的剩余电量相较于第一电量区间高。处理器可以判断当前转速是否处于预设燃油经济转速区间。若当前转速不处于预设燃油经济转速区间，此时油耗较高且高压电池包的剩余电量较高，因此为减少发电机消耗的燃油，处理器可以确定发电机的输出功率为第三输出功率，以达到降低搅拌车油耗的目的，其中第三输出功率根据实际情况确定，需小于第二输出功率。
在本申请实施例中，电量区间还可以包括第三电量区间，该控制方法还可以包括：在当前工作状态为行驶状态且电量区间为第三电量区间的情况下，控制发电机停止输出功率。
具体地，在当前工作状态为行驶状态且电量区间为第三电量区间的情况下，高压电池包的剩余电量高，具有足够的电能输出至电机驱动器，此时，处理器可以控制发电机停止工作，以减少搅拌车的油耗。
需要说明的是，在搅拌车处于行驶状态时，若刹车制动，那么搅拌车可以启动能量回收，从而为高压电池包反向充电，实现制动能量的回收利用。
在本申请实施例中，搅拌机还可以包括远程油门，当前工作状态可以包括怠速状态，电量区间包括第四电量区间，根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，可以包括：在当前工作状态为怠速状态、电量区间为第四电量区间且远程油门开启的情况下，调节当前转速，使当前转速处于预设燃油经济转速区间，并确定发电机的输出功率为第一输出功率；在当前工作状态为怠速状态、电量区间为第四电量区间且远程油门闭合的情况下，确定发电机的输出功率为第四输出功率；其中，第四输出功率小于第一输出功率。
需要说明的是，怠速状态下的电量区间与行驶状态下的电量区间的划分不同，也就是说，行驶状态下的第一电量区间、第二电量区间和第三电量区间与怠速状态下的第四电量区间、第五电量区间的范围具有重合的可能性，具体范围需根据实际作业工况确定。具体地，远程油门是可以控制与发动机转速相关的辅助功能的油门。在当前工作状态为怠速状态、电量区间为第四电量区间且远程油门开启的情况下，此时搅拌车油耗较低且高压电池包的剩余电量较低，由于远程油门处于开启状态，处理器可以将发动机的当前转速调节至预设燃油经济转速区间，并确定发电机的输出功率为第一输出功率。而在远程油门处于闭合状态时，处理器不需要调节发动机的当前转速，发动机的当前转速不处于预设燃油经济转速区间，因而搅拌车的油耗相比远程油门开启时的油耗较高，此时处理器可以确定发电机的输出功率为第四输出功率。其中，第四输出功率根据实际情况确定，需小于第三输出功率。可以理解地，在第四输出功率小于第三输出功率的情况下，第四输出功率必然小于第一输出功率。
在本申请实施例中，电量区间还包括第五电量区间，该控制方法还可以包括：在当前工作状态为怠速状态且电量区间为第五电量区间的情况下，控制发动机熄火，并控制发电机停止输出功率。
具体地，在电量区间为第五电量区间时，高压电池包的剩余电量相较于第四电量区间高。由于搅拌车处于怠速状态，车辆没有行驶需求，并且高压电池包的剩余电量较高，处理器可以控制发动机熄火，并控制发电机停止输出功率，从而减少搅拌车的油耗。
综上，与现有技术相比，本申请提供的技术方案具有以下优点：
1)本申请实时地根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，可以减少搅拌车的油耗，降低搅拌车的使用成本，提高施工效率。
2)本申请的高压电池包可以通过充电桩充电，也可以由发电机充电，有效降低高压电池包电量耗尽的风险。
3)通过电能驱动搅拌筒转筒，其响应速度快，控制精度高，可以保障搅拌筒转速的稳定性。

在一个实施例中，处理器进一步被配置成：在当前工作状态为怠速状态且电量区间为第五电量区间的情况下，控制发动机熄火，并控制发电机停止输出功率。
上述技术方案，在发动机启动的情况下，获取高压电池包的剩余电量、发动机的当前转速以及搅拌车所处的当前工作状态，再确定剩余电量所在的电量区间，进而根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，最后控制发电机按照输出功率工作，以由发电机为高压电池包充电。本申请实时地根据电量区间、预设燃油经济转速区间、当前转速以及当前工作状态确定发电机的输出功率，可以在搅拌车的油耗较高且高压电池包的剩余电量充足时降低发电机的输出功率，在油耗较低且高压电池包的剩余电量不足时增加发电机的输出功率，从而减少搅拌车的油耗，降低搅拌车的使用成本。
图2示意性示出了根据本申请实施例的一种搅拌车的结构图。如图2所示，本申请实施例还提供一种搅拌车，可以包括：高压电池包14；发动机；发电机7；以及处理器。
具体地，搅拌车包括显示屏1、分动箱2、电机3、操作面板4、遥控收发装置5、控制器6、发电机7、低压转换器8、发电机控制器9、电机驱动器10、热管理器11、底盘12、低压电瓶13和高压电池包14。其中，控制器6包括处理器和存储器。当底盘的钥匙开关处于开启档位时，控制器6唤醒显示屏1、低压转换器8、发电机控制器9、电机驱动器10、热管理器11和高压电池包14。唤醒后，低压转换器8、发电机控制器9、电机驱动器10、热管理器11和高压电池包14进行自检运行，同时通过显示屏1显示低压转换器8、发电机控制器9、电机驱动器10、热管理器11和高压电池包14的自检状态和自检参数。如此，与显示屏1通信的控制器6可以根据自检状态和自检参数进行故障诊断并输出检修方法。
显示屏1、操作面板4以及遥控收发装置5均可控制搅拌筒启停，同时也可以调节搅拌筒的转速，即使在底盘12的发动机未启动时也可以实现无油耗状态下的搅拌作业。高压电池包14是包括电池和电池管理系统的储能装置，可以通过高压充电枪充电，也可以通过发电机7充电，用于为电机驱动器10供能，以驱动电机3带动搅拌筒转筒。分动箱2为动力切换的执行装置，可以在电机驱动器10故障时切换动力，以底盘12的发动机带动搅拌筒进行转筒。发电机控制器9根据控制器6确定的输出功率控制发电机7按照输出功率工作，从而为高压电池包14充电。低压转换器8可以从高压电池包14获取电能，从而为低压电瓶13充电。低压电瓶13可以为搅拌车的小功率子系统供电。
热管理器11可以作为搅拌车驾驶室的制冷装置，也可以根据电机3、电机驱动器10、发动机7和发电机控制器9的温度进行散热。在一个示例中，若电机3、电机驱动器10、发动机7和发电机控制器9中的任意一个装置的温度达到第一预设温度，则热管理器11启动并以第一散热档位进行温度调节，即仅通过水泵进行降温。若电机3、电机驱动器10、发动机7和发电机控制器9中的任意一个装置的温度达到第二预设温度，则热管理器11以第二散热档位进行温度调节，即通过散热风扇和水泵进行降温。若电机3、电机驱动器10、发动机7和发电机控制器9中的任意一个装置的温度达到第三预设温度，则热管理器11以第三散热档位进行温度调节，即通过散热风扇和水泵进行降温，此时散热风扇的功率高于第二散热档位的散热风扇的功率。若电机3、电机驱动器10、发动机7和发电机控制器9中的任意一个装置的温度达到第四预设温度，则热管理器11以第四散热档位进行温度调节，即通过空调进行降温。其中，第一预设温度小于第二预设温度，第二预设温度小于第三预设温度，第三预设温度小于第四预设温度。此外，可以用散热器替换热管理器11。
