    • PURPOSE: A controlling system for prevention of rapid start of a vehicle is provided to prevent rapid start and wrong operation of an accelerator pedal through controlling injection amount of fuel and engine RPM(Revolutions Per Minute) in case of stepped state of the accelerator pedal while not stepping on the pedal. CONSTITUTION: An engine controlling device is formed by comparators(COMP1,COMP2) comparing input engine RPM and vehicle speed with reference values; an AND gate(AND1) AND operating the comparators; a logic switch(SW) selecting the engine RPM or the vehicle speed according to selected gear; a comparator(COMP3) comparing an input throttle position signal with a reference value; a comparator(COMP4) subtracting a present throttle position signal from a prior valve for comparing with a reference value; an AND gate(AND2) AND operating the comparing values; an AND gate(AND3) AND operating a brake switch and a dual brake switch value; an AND gate(AND4) AND operating the value from the AND gate and a switch signal; an AND gate(AND5) AND operating values from the gates(AND3,AND4); a timer(TM) counting time; a comparator(COMP5) comparing a counted time with a reference time; and a preventive logic of wrong operation in an accelerator pedal reducing the engine RPM and fuel injection amount according to output of the comparator.
    • 目的:提供一种用于防止车辆快速启动的控制系统,以防止在加速踏板的阶梯状态的情况下通过控制燃料喷射量和发动机转速(每分钟转数)快速启动和错误操作加速器踏板,同时 没有踩踏板。 构成:比较器(COMP1,COMP2)将输入引擎转速和车速与参考值进行比较,形成发动机控制装置; AND门(AND1)并操作比较器; 逻辑开关(SW)根据所选择的档位选择发动机转速或车速; 将输入节气门位置信号与参考值进行比较的比较器(COMP3); 比较器(COMP4)从现有阀减去当前节气门位置信号,与参考值进行比较; AND门(AND2)AND操作比较值; AND门(AND3)AND操作制动开关和双制动开关值; 与门(AND4)AND AND AND AND AND AND AND开关信号; AND门(AND5)AND来自门(AND3,AND4)的AND操作值; 计时器(TM)计时; 将计数时间与参考时间进行比较的比较器(COMP5); 以及根据比较器的输出,在加速踏板中错误操作的预防逻辑,其减小发动机RPM和燃料喷射量。
