S300、当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统开启；
S400、当所述双制冷车载冰箱所处的环境条件未满足所述预定环境条件时，控制所述压缩机制冷系统关闭，同时控制所述半导体制冷系统开启。
在车辆的行驶过程中，车辆内部的温度、以及车辆本身的所处的坡度会发生变化。对于制冷效果较好的压缩机制冷系统而言，当车辆内部温度较高(超过预定温度)时，压缩机制冷系统的制冷效果将下降。并且，当车辆所处的坡度较大时，润滑油将流入压缩机制 冷系统，并损坏压缩机制冷系统。
在本发明所提供的控制方法中，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，所述压缩机制冷系统处于较优的工作状态，可以达到较好的制冷效果。因此，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，开启所述压缩机制冷系统进行制冷。
当安装所述双制冷车载冰箱的车辆内部温度超过预定温度时，因此，可以控制压缩机制冷系统关闭，利用半导体制冷系统进行制冷，从而可以确保当车内温度较高时，所述双制冷车载冰箱仍然具有较好的制冷效果。
当承载所述双制冷车载冰箱的测车辆所处的坡度超过所述预定坡度时，控制所述压缩机制冷系统停止工作，从而可以防止润滑油流入压缩机制冷系统，进而可以避免压缩机制冷系统收到损坏。
因此，本发明所提供的控制方法控制所述双制冷车载冰箱进行制冷，使得所述双制冷车载冰箱能够在车辆行驶的过程中实现较好的制冷效果，并且，可以确保双制冷车载冰箱不会发生损坏。
需要解释的是，如果在执行步骤200时是基于第三种实施方式(即同时考虑所述双制冷车载冰箱所处的环境温度以及承载所述双制冷车载冰箱的车辆所处的坡度的实施方式)，则在步骤S400中所述的“所述双制冷车载冰箱所处的环境条件未满足所述预定环境条件”包括如下三种情况：一、所述双制冷车载冰箱所处的环境温度不低于所述预定温度、且承载所述双制冷车载冰箱的车辆所处的坡度不小于所述预定坡度；二、所述双制冷车载冰箱所处的环境温度低于所述预定温度、且承载所述双制冷车载冰箱的车辆所处的坡度不小于所述预定坡度；三、所述双制冷车载冰箱所处的环境温度不低于所述预定温度、且承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。
以及，在步骤S200中，可以先判断所述双制冷车载冰箱所处的温度是否低于所述预定温度、再判断所述车辆所处的坡度是否低于所述预定坡度；也可以先判断所述车辆所处的坡度是否低于所述预定坡度、再判断所述双制冷车载冰箱所处的温度是否低于所述预定温度。
在一种实施方式中，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统开启的同时，还可以控制所述半导体制冷系统开启。
不过，由于当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，采用压缩机制冷系统就可以达到较好的制冷效果，能够满足制冷需求，因此，为了降低双制冷车载冰箱的能耗，在另一种实施方式中，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统开启的同时，控制所述半导体制冷系统关闭。由 此，可以同时满足制冷需求和低能耗需求。
在本发明中，对所述预定温度的具体值并没有特殊的要求，所述预定温度由所述压缩机制冷系统所采用的制冷剂的特性所决定。作为一种具体实施方式，所述制冷剂可以为绿色环保制冷剂R134a(即，1，1，1，2-四氟乙烷)或者制冷剂R600a(即，异丁烷)，在这种情况中，所述预定温度可以在50℃至60℃之间。进一步优选地，所述预定温度可以为55℃。
可选的，所述预定坡度可以由整车制造厂根据其选用压缩机制冷系统的特点来设置。
为了便于实现所述车载冰箱控制的自动化，可选的，所述控制方法还包括：
S100、判断接收到的工作指令是否为双制冷车载冰箱工作指令；和
S500、当接收到的工作指令不是所述双制冷车载冰箱工作指令时，控制压缩机制冷系统和半导体制冷系统均关闭。
容易理解的是，在整个控制方法中，在执行步骤S200之前执行步骤S100。
为了使得所述控制方法适用于多种不同型号、不同结构的双制冷车载冰箱，优选地，所述控制方法还可以包括在步骤S100之前进行的：
设定所述预定环境条件。
作为本发明的另一个方面，如图2所示，提供一种双制冷车载冰箱的控制器230，该控制器230用于执行本发明所提供的上述控制方法，其中，所述双制冷车载冰箱包括压缩机制冷系统210和半导体制冷系统220。具体地，控制器230可以包括环境判定模块231和控制模块232。
控制模块232用于在接收到的工作指令是双制冷车载冰箱工作指令时，控制环境判定模块231执行步骤S200，具体地，控制环境判定模块231检测所述双制冷车载冰箱所处的环境条件。
控制模块232还用于将环境判定模块231检测到的环境条件与预定环境条件进行对比，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制压缩机制冷系统210开启。并且，控制模块232还用于在环境判断模块231检测到的环境条件未满足所述预定环境条件时，控制压缩机制冷系统210关闭，同时控制半导体制冷系统220开启。
控制器230用于执行图1中的步骤S200、步骤S300和步骤S400。具体地，控制模块232用于在所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统开启(即，执行步骤S300)。并且，控制模块232还用于在环境判断模块231检测到环境条件未满足所述预定环境条件时，控制压缩机制冷系统210关闭，同时控制半导体制冷系统220开启(即，执行步骤S400)。
其中，环境判定模块231在执行步骤S200时，可以通过以下几种方式：
在一种实施方式中，所述环境条件包括所述双制冷车载冰箱所处的温度，所述预定环境条件包括预定温度，则双制冷车载冰箱所处的环境条件满足所述预定环境条件包括：所述双制冷车载冰箱所处的温度低于所述预定温度。
在另一种实施方式中，所述环境条件包括承载所述双制冷车载冰箱的车辆所处的坡度；所述预定环境条件包括预定坡度，则双制冷车载冰箱所处的环境条件满足所述预定环境条件包括：承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。
优选的，在又一种实施方式中，所述环境条件包括所述双制冷车载冰箱所处的温度以及承载所述双制冷车载冰箱的车辆所处的坡度；所述预定环境条件包括预定温度和预定坡度，双制冷车载冰箱所处的环境条件满足所述预定环境条件包括：所述双制冷车载冰箱所处的温度低于所述预定温度，以及承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。
需要解释的是，如果在执行步骤200时是基于第三种实施方式(即同时考虑所述双制冷车载冰箱所处的环境温度以及承载所述双制冷车载冰箱的车辆所处的坡度的实施方式)，则“环境判断模块231检测到环境条件未满足所述预定环境条件”包括如下三种情况：一、环境判断模块231检测到的环境温度不低于所述预定温度、且环境判断模块231检测到的坡度不小于所述预定坡度；二、环境判断模块231检测到的环境温度低于所述预定温度、且环境判断模块231检测到的坡度不小于所述预定坡度；三、环境判断模块231检测到的环境温度不低于所述预定温度、且环境判断模块231检测到的坡度小于所述预定坡度。
可选的，控制模块232可以在所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统210开启的同时还控制半导体制冷系统220关闭。由此，可以同时满足制冷需求和低能耗需求。
作为本发明的具体实施方式，环境判定模块231可以包括温度传感器231a和角度传感器231b。温度传感器231a用于检测所述双制冷车载冰箱所处的环境温度，角度传感器231b用于检测所述双制冷车载冰箱所处的车辆的坡度。
控制模块232用于将温度传感器231a检测到的环境温度与所述预设温度进行比较，且控制模块232用于将角度传感器231b检测到的坡度与所述预设坡度进行比较。当然，如果环境判定模块231在执行步骤S200时是基于前两种实施方式(即只考虑所述双制冷车载冰箱所处的环境温度，或者只考虑所述双制冷车载冰箱所处的车辆的坡度的方式)，则环境判定模块231中可以只包括温度传感器231a，或者只包括角度传感器231b。
如上文中所述，在本发明中，对所述预定温度的具体值并没有特殊的要求，所述预定温度由所述压缩机制冷系统所采用的制冷剂的特性所决定。作为一种具体实施方式，所述制冷剂可以为绿色环保制冷剂R134a(即，1，1，1，2-四氟乙烷)或者制冷剂R600a(即， 异丁烷)，在这种情况中，所述预定温度在50℃至60℃之间。进一步优选地，所述预定温度可以为55℃。
可选的，所述预定坡度由整车制造厂根据其选用压缩机制冷系统的特点来设置。
为了便于执行步骤S100，优选地，控制模块232还用于判断接收到的工作指令是否为所述双制冷车载冰箱工作指令，当所述控制模块接收到的工作指令不是所述双制冷车载冰箱工作指令时，控制模块232还用于控制环境判定模块231休眠，并控制压缩机制冷系统210和半导体制冷系统220均关闭。
可选的，控制器230还包括输入模块233，输入模块233用于将所述预定温度和/或所述预定坡度写入所述控制模块。
在本发明中，对输入模块233的具体结构并没有特殊的要求，只要能够输入所述预定温度和/或所述预定坡度即可。例如，所述输入模块233可以为键盘输入模块，或者，输入模块233还可以为触摸屏。
作为本发明的还一个方面，提供一种双制冷车载冰箱，如图2所示，所述双制冷车载冰箱包括压缩机制冷系统210和半导体制冷系统220，其中，所述双制冷车载冰箱还包括控制器230，该控制器230为本发明所提供的上述控制器。
