The invention discloses a fuel control system and method for a double-fuel-tank vehicle and the double-fuel-tank vehicle, and the system comprises a first controller which is configured to obtain the fuel liquid level deviation in a main fuel tank in the operation process of the double-fuel-tank vehicle; an opening degree signal used for adjusting the opening degree of the oil pumping adjusting valve is generated according to the fuel oil liquid level deviation; the second controller is configured to adjust the oil pumping adjusting valve to the corresponding opening degree according to the opening degree signal received from the first controller; acquiring fuel consumption of a main oil tank and oil pumping quantity of an oil pump; and the opening degree of the oil pumping adjusting valve is adjusted in real time according to the fuel oil consumption and the oil pumping amount. Through cascade control of the first controller and the second controller, the current liquid level of the main oil tank can be effectively kept unchanged, and the liquid level stability during oil supplementing can be guaranteed, so that the running stability of the vehicle is improved.
本发明公开一种用于双油箱车辆的燃油控制系统、方法及双油箱车辆,系统包括第一控制器,被配置成:在双油箱车辆运行过程中获取主油箱内的燃油液位偏差;根据燃油液位偏差生成用于调整泵油调节阀的开启度的开启度信号;第二控制器,被配置成:根据从第一控制器接收的开启度信号将泵油调节阀调整至对应的开启度;获取主油箱的燃油消耗量和油泵的泵油量;根据燃油消耗量和泵油量实时调整泵油调节阀的开启度。通过第一控制器和第二控制器的串级控制,能够有效维持主油箱的当前液位不变,并能够保证补油时的液位稳定,从而提高车辆运行的稳定性。
