Abstract: PURPOSE: A method for compensating errors about the idle decision for a vehicle is provided to improve the problems in driving about the idle decision errors and degrade the recall rate of the vehicle. CONSTITUTION: When the vehicle is in stop condition and the range of target RPM, and a TPS variation is in the range of an idle decision TPS variation, a method checks whether the TPS output is less than the added value of a higher value of the previous TPS output and previous studied value to the TPS return variation for the idle decision. If it is checked as the TPS output is less than the added value, an idle decision delay count is initialized to zero. The present idle decision delay count is set by increasing the previous idle decision count by one. The method checks whether the idle count is more than the number of idle decision delay. If the idle count is more than the number of idle decision delay, the TPS output is set as the TPS studied value and the idle count is deleted, and then the idle flag is converted to be on.

Abstract: PURPOSE: A method for compensating for a map output value is provided to prevent a shock from being generated when a variation of load is shifted by compensating for an amount of intake air. CONSTITUTION: Driving information is detected(S101). A gain regarding to an amount of air is detected from information which is varied depending on a driving condition of a vehicle(S102). Then, a control section determines whether the detected gain exceeds the gain obtained in an idle state or in a partially loaded state(S103). According to the determination of the control section, the compensating value regarding to the amount of air is determined. Then, the amount of the air is compensated by the determined value and the amount of fuel according to the amount of intake air is calculated(S108).

Abstract: PURPOSE: A method for compensating for an amount of air is provided to stably compensate for an idle engine RPM by providing an amount of air based on accumulated data when the idle engine RPM is varied. CONSTITUTION: A control section detects signals applied from an engine RPM detecting section and an ISC opening degree detecting section(S101). If the engine is in an idle state, the control section determines whether it is required to compensate for the amount of air(S102). If the compensation is required, the control section determines the initial compensating value(S103) and calculates the driving time of an actuator(S104). Then, the control section sets an optimum idle RPM, and determines the amount of intake air thereof as a reference value(S107). The reference value is stored in a memory section.

Abstract: PURPOSE: A method for compensating asynchronic injection quantity by disposing the condition of the asynchronic compensation injection in two way, which is in idling and in idling-off to use fuel efficiently. CONSTITUTION: An idle state is read by detecting electrical signals output from a car speed sensor and a throttle position sensor. When it is idle state, whether a change of opening degree of the throttle valve is detected as a condition for an asynchronic injection is decided. When it is detected as an asynchronic injection condition, an asynchronic injection compensation is carried out by a set program in an idle state. In the step of reading an idle state, when it is detected as a load operation state, an asynchronic injection condition is detected. In the load operation of above step, if it is read as the asynchronic injection condition, an asynchronic injection compensation is carried out.

Abstract: PURPOSE: A method for limiting a temperature of an exhaust gas is provided to prevent a thermal damage of an engine and a catalyst material due to a high temperature of the exhaust gas by limiting the temperature of the exhaust gas not to exceed a limited value when overloading of the engine. CONSTITUTION: A compensation initial value(INJINI) of a fuel amount is set zero, and whether or not a temperature of an exhaust gas is a limited value or larger, is confirmed. If yes, the fuel amount is controlled by operating a compensation fuel amount(INJw), while increasing a compensation value(INJIi) of the fuel amount. If the compensation fuel amount(INJw) is the compensation value(INJIi) or larger, a fuel amount compensation control is terminated.

Abstract: 본 발명은 엔진의 시동시 분사되는 연료의 양을 적절히 제어하도록 하기 위한 것으로서, 엔진이 시동된 직후에 엔진에 제공되는 과도 연료가 점차 저감되도록 하는 과정을 포함하는 연료 분사량 제어방법에 있어서, 냉각수온의 변화에만 의존한 연료분사량 보정치가 냉각수온과 시동시간 및 배터리 상태에 의존하는 연료분사량 보정치보다 작아지는 시점에서 연료분사량 제어를 정상상태의 연료분사량제어로 변화시키도록 하는 과정을 포함하여 구성된 연료 분사량 제어방법을 제공하여, 엔진의 시동초기에 과도하게 분사되다가 엔진의 상태가 정상상태로 접어듦에 따라 감소되는 연료 분사량 보정치에 의해 실제 엔진에서 필요한 연료보다 적은 연료를 엔진에 공급하게 되는 경우를 배제하도록 하여 엔진의 안정적인 시동성능을 확보할 수 있도록 하 는 효과를 얻을 수 있다.
