    • An engine torque control method is provided to maintain constant acceleration feeling of a vehicle because the engine torque increases and The torque degradation caused by RPM degradation is prevented. An engine torque control method comprises a first step which inputs an acceleration pedal signal of an operator; a second step which determines a direct-coupling condition of a transmission and an engine according to the signal in the vehicle acceleration; a third step which increases an actuator operation duty for direct-coupling a damper clutch when the direct-coupling condition is satisfied; a fourth step which determines whether the damper clutch is direct-coupled or not after the operation duty raise up; a fifth step which compensates for the torque when the damper clutch is direct-coupled; a sixth step which calculates the fuel air volume after the torque compensation; and a seventh step which converts into a TPS(Throttle Position Sensor) according to the calculated necessary engine output, and opens and closes the throttle valve.
    • 提供发动机扭矩控制方法,以保持车辆的恒定的加速感觉,因为发动机扭矩增加,并且防止了由RPM降低引起的扭矩劣化。 发动机转矩控制方法包括:输入操作者的加速踏板信号的第一步骤; 第二步骤,根据车辆加速度中的信号确定变速器和发动机的直接耦合状态; 第三步骤,当满足直接耦合条件时,增加用于直接联接阻尼器离合器的致动器操作负荷; 第四步骤,在操作负荷提高之后,确定阻尼离合器是否直接耦合; 第五步,当阻尼离合器直接联接时补偿扭矩; 计算转矩补偿后的燃料空气量的第六步骤; 以及第七步骤,根据计算的必要发动机输出转换成TPS(节气门位置传感器),并且打开和关闭节气门。

    • A fuel conversion controlling method of a bi fuel vehicle operating an engine is provided to prevent engine torque from being lowered by operating an engine with gasoline fuel and CNG fuel in case the driving of full load condition is demanded in a CNG fuel mode. A fuel conversion controlling method of a bi fuel vehicle operating an engine comprises: a step(101,103) for receiving fuel conversion signals supplied from outside and determining whether present use fuel is gasoline fuel or not and converting the fuel mode into a CNG fuel mode in case the present use fuel is the gasoline fuel; a step(107) for determining driving demand of full load state according to acceleration will of a driver in the CNG fuel mode; and a step(109) for operating the engine with the gasoline fuel and the CNG fuel in case the driving demand of full load state is received.
    • 提供了操作发动机的双燃料车辆的燃料转换控制方法,以在以CNG燃料模式要求满载条件的情况下操作具有汽油燃料和CNG燃料的发动机来防止发动机转矩降低。 操作发动机的双燃料车辆的燃料转换控制方法包括:步骤(101,103),用于接收从外部供应的燃料转换信号,并确定当前使用燃料是否是汽油燃料,并将燃料模式转换成CNG燃料模式 目前使用的燃料是汽油燃料; 用于根据CNG燃料模式中的驾驶员的加速度确定满载状态的驾驶需求的步骤(107); 以及用于在接收到满载状态的驱动需求的情况下用汽油燃料和CNG燃料操作发动机的步骤(109)。
