The invention provides an engine rear-mounted vehicle and a rear cabin door control method and device thereof, and belongs to the technical field of automobile electronics. The method comprises the steps that signals are collected in the vehicle driving process, control conditions of a rear cabin door are generated according to the collected signals, the control conditions comprise at least one of the following judgment conditions, and the first judgment condition is that whether current vehicle driving state signals meet a first set threshold value range; the second judgment condition is that whether the environment signal of the current engine compartment meets a second set threshold value range; and the third judgment condition is that whether the running state signal of the current engine meets a third set threshold value range; the control condition is judged and a rear cabin door control signal is output; according to the rear cabin door control signal, the rear cabin door is controlled to open and close a cabin door opening in an up-down moving mode. The rear cabin door is in the open state, aerodynamic resistance borne by the vehicle in the running process can be rapidly reduced, the resistance reducing effect is obvious, the original structure of the vehicle does not need to be changed, and cost is low.

    本发明提供一种发动机后置车辆及其后舱门控制方法和装置,属于汽车电子技术领域。该方法包括:在车辆行驶过程中采集信号,根据采集的信号生成后舱门的控制条件,控制条件包括以下判断条件中的至少一个,判断条件一:当前车辆行驶状态信号是否满足第一设定阈值范围;判断条件二:当前发动机舱的环境信号是否满足第二设定阈值范围;判断条件三:当前发动机的运行状态信号是否满足第三设定阈值范围;对所述控制条件进行判断并输出后舱门控制信号;根据后舱门控制信号,控制后舱门以上下移动的方式开闭舱门口。本发明通过使后舱门处于开启状态,能使车辆行驶中所受的气动阻力迅速减少,减阻效果明显,且无需改变车辆原有结构,成本较低。
