The invention provides a method for detecting the information of a fuel tank being used in a double-fuel-tank vehicle model. The method comprises a method for identifying the fuel tank which is being used in the double-fuel-tank vehicle model. The method for identifying the fuel tank which is being used in the double-fuel-tank vehicle model comprises the following steps: S1, in a vehicle driving process, a vehicle control unit collects fuel quantity sensor signal resistance values R of a first fuel tank and a second fuel tank; S2, the vehicle control unit calculates the average fuel quantity sensor resistance value delta R; S3, the vehicle control unit stores the fuel quantity sensor signal resistance values R of the first fuel tank and the second fuel tank, draws an average resistance change curve, and judges the state of the fuel tank in use according to the slope of the average resistance change curve of the fuel tanks; and S4, the vehicle control unit sends a judgement result in the step S3 to an instrument, and the instrument displays whether the first fuel tank or the second fuel tank is being used. Compared with the prior art, the function of synchronously displaying the fuel tank in use to the instrument can be achieved.

    本发明提供一种双油箱车型中正在使用油箱信息的检测方法,包括识别双油箱车型中正使用油箱的方法,所述识别双油箱车型中正使用油箱的方法包括如下步骤:S1,车辆行驶过程中,整车控制器采集第一油箱和第二油箱的油量传感器信号电阻值R,S2,整车控制器计算油量传感器电阻平均值δR;S3,整车控制器储存第一油箱和第二油箱的油量传感器信号电阻值R并绘制平均电阻变化曲线,并根据油箱平均电阻变化曲线的斜率判断正在使用的油箱状态,S4,整车控制器将步骤S3中的判断结果发给仪表,仪表显示正在使用的是第一油箱或第二油箱。与现有技术相比,本发明可实现正在使用的油箱同步显示到仪表的功能。
