The embodiment of the invention provides an anti-oil-return control device, method and system and a vehicle, and the device comprises a control valve which is arranged at one end, close to an auxiliary oil tank, of a connecting oil pipe of a main oil tank and an auxiliary oil tank; the control valve is in a normally open state; and the control valve is switched to a closed state when receiving a closing instruction. The method comprises the steps of obtaining vehicle condition information of a vehicle and the remaining oil amount of a main oil tank; detecting an uphill angle of the current position of the vehicle on the basis of the current remaining oil quantity of the main oil tank; and controlling a control valve to be closed according to the uphill angle of the current position or under the condition that the vehicle condition information of the vehicle is a collision vehicle condition. The situation that fuel oil in the main oil tank flows back to the auxiliary oil tank under the special working condition of a vehicle, and consequently oil supply of the main oil tank is insufficient under the special working condition can be effectively avoided.
本申请实施例提供的一种防回油控制装置、方法、系统及车辆,包括:控制阀,设置在所述主副油箱连接油管的靠近副油箱一端;所述控制阀处于常开状态;所述控制阀在接收到关闭指令时切换至关闭状态。通过获取车辆的车况信息和主油箱的剩余油量;基于所述主油箱当前的剩余油量,检测所述车辆当前位置的上坡角度;根据所述当前位置的上坡角度,或在所述车辆的车况信息为发生碰撞的车况的情况下,控制控制阀关闭。可以有效避免车辆在特殊工况下,主油箱内燃油回流至副油箱,导致主油箱在特殊工况下供油不足的情况发生。
