Abstract: PURPOSE: An engine torque control method of an automatic transmission is provided to prevent engine stall by disregarding torque down demand of a TCU(Transmission Control Unit) in case of the idle fuel amount to be less than the minimum fuel amount for starting in shifting N into D-range and accelerating suddenly simultaneously. CONSTITUTION: Information on state of a vehicle is detected by a TCU(S101), and torque control condition is decided to be satisfied with information detected at idling an engine(S102). An ECU(Electronic Control Unit) detects the fuel amount for keeping idle rpm according to the torque-down demand signal from the TCU, and compares the detected fuel amount with the minimum fuel amount for starting(S103,S104). The current fuel amount is kept by disregarding the torque-down demand, and engine torque is controlled according to travel demand(S105,S106). The torque-down fuel amount is calculated through algorithm if the current fuel amount is more than the minimum starting fuel amount, and engine torque down control is performed by driving an injector(S107,S108). The reliability is improved by restricting engine stall.
Abstract translation: 目的：提供一种自动变速器的发动机转矩控制方法，以防止发动机失速，因为在空转燃料量小于用于开始变速N的最小燃料量时，不考虑TCU（变速器控制单元）的转矩下降需求 进入D范围并同时加速。 构成：通过TCU检测车辆的状态信息（S101），判定为在发动机怠速时检测到的信息满足转矩控制条件（S102）。 ECU（电子控制单元）根据来自TCU的转矩下降需求信号检测用于保持怠速转速的燃料量，并将检测到的燃料量与用于起动的最小燃料量进行比较（S103，S104）。 通过忽视转矩下降需求来保持当前燃料量，并且根据行驶需求来控制发动机扭矩（S105，S106）。 如果当前燃料量大于最小启动燃料量，通过算法计算出转矩下降燃料量，并通过驱动喷油器进行发动机转矩下降控制（S107，S108）。 通过限制发动机停转来提高可靠性。

Abstract: PURPOSE: A method for controlling a diesel engine of a vehicle is provided to allow drivers to safely drive a vehicle by maintaining an engine R.P.M in an idle state when contact errors of sensors occur. CONSTITUTION: When an engine is in an ignition-on state, a control section analyzes present shift lever position information, engine R.P.M information, driving condition information, acceleration pedal information, and present vehicle speed information, thereby determining whether a present condition satisfies a safe mode control(S101,S102,S103). If the safe mode control is satisfied, the control section determines that a contact error of sensors occurs(S104). Thus, the control section controls a governor actuator so as to supply fuel into a combustion chamber corresponding to an idle rotation, thereby limiting an engine R.P.M(S105). If an ignition-off of an engine is detected, the safe mode control is reset(S106,S107). If the safe mode control is not satisfied, a normal control is carried out(S108).
Abstract translation: 目的：提供一种用于控制车辆的柴油发动机的方法，以便当传感器发生接触错误时，通过将发动机R.P.M保持在空闲状态来允许驾驶员安全驾驶车辆。 构成：当发动机处于点火开关状态时，控制部分分析当前变速杆位置信息，发动机转速信息，行驶状态信息，加速踏板信息和当前车速信息，从而确定当前状况是否满足安全 模式控制（S101，S102，S103）。 如果满足安全模式控制，则控制部确定发生传感器的接触错误（S104）。 因此，控制部分控制调速器致动器以将燃料供应到与空转相对应的燃烧室中，从而限制发动机R.P.M（S105）。 如果检测到发动机的点火开关，则复位安全模式控制（S106，S107）。 如果不满足安全模式控制，则进行正常控制（S108）。

Abstract: PURPOSE: A control method of exhaust gas in a diesel vehicle is provided to satisfy the regulation of exhaust gas by injecting fuel of a map value to be matched to a pre-acceleration condition. CONSTITUTION: The information of a vehicle to be detected when the starting of an engine is maintained(S101-S106). A fuel injected amount value is accessed by applying to a map table when the information is a condition for an exhaust gas test at a pre-acceleration(S107). An injection to a combustion chamber is performed by the corresponding fuel injected amount value. Otherwise, a fuel injected amount value is accessed and the injection is performed by applying to a map table of a driving mode(S109). Thereby, the reliability of a vehicle is improved, the generation of an air pollution is eliminated and the stable concentration of exhaust gas is maintained.
