    • An exhaust gas recirculation device for an internal combustion engine includes: an opening command signal output unit 52 which outputs an opening command signal in relation to an EGR control valve on the basis of an operating condition of the internal combustion engine; a variation component separation unit 54 which separates the valve opening command signal from the opening command signal output unit 52 into a basic component and a variation component generated so as to be superimposed on the basic component; a variation component determination unit 56 which determines whether the EGR control valve is in a steady state or a transient state on the basis of a magnitude of the variation component separated by the variation component separation unit 54; and an EGR control valve diagnosis device 58 that performs an abnormality diagnosis on the EGR control valve when the variation component determination unit determines that the EGR control valve is in the steady state.
    • 用于内燃机的排气再循环装置包括:开启指令信号输出单元52,其基于内燃机的运行状态输出关于EGR控制阀的打开指令信号; 将打开指令信号从打开指令信号输出部52分离成基本部分的变化部分分离部54和生成为与基本部分重叠的变化成分; 变动分量确定单元56,其基于由变化分量分离单元54分离的变化分量的大小来确定EGR控制阀是处于稳定状态还是过渡状态; 以及EGR控制阀诊断装置58,其在变更分量判定部判定为EGR控制阀处于稳定状态时,对EGR控制阀进行异常诊断。

    • A steering control device obtains a command steering reactive force according to a wheel angle based on a wheel angle and table data representing the correlation between the wheel angle and the command steering reactive force, and which controls an electric-control brake to make the steering reactive force equal to the command steering reactive force. The steering control device: obtains a correction coefficient according to vehicle state amounts based on the vehicle state amounts other than the wheel angle, which are detected by vehicle state amount detecting means, and table data representing the correlation between the vehicle state amounts and the correction coefficients; corrects the table data by using the correction coefficients; obtains a command steering reactive force according to the wheel angle based on the table data and the wheel angle; and controls the electric-control brake to make the steering reactive force equal to the command steering reactive force.
