Abstract: The present invention prevents an EGR sensor installed in an engine's EGR path from being soiled by soiling substances in exhaust. A catalyst is positioned upstream of the EGR sensor to purify the soiling substances in EGR gas. The status of the EGR sensor is properly controlled in accordance with the conditions of the catalyst. This ensures the EGR sensor is less likely to be affected by the soiling substances in the exhaust under any circumstances of the EGR path and allows the EGR sensor to avoid a decrease in the accuracy of EGR gas detection. An alternative configuration may be employed such that the EGR gas recirculates from the downstream side of a catalyst installed in a main exhaust path.

Abstract: In order to accomplish the above-mentioned and other objects, an anti-skid control system, takes a procedure for sampling input timing data of every given number of sensor signals, which given number is adjusted so as to a difference of period of time measured with respect to mutually adjacent signal-to-signal intervals is great enough to perform the anti-skid control operation based thereupon. The anti-skid control system processes the input timing data for deriving a wheel speed, a wheel acceleration and deceleration and so forth based on the input timing data. The wheel acceleration and deceleration is calculated based on the successively sampled three input timing data. An input timing data is sampled relative to a first sensor signal at which procedure for determining the input timing data sample mode starts, as a first input timing data.
