The cruise control apparatus includes a preceding vehicle position storage unit, a course prediction computation unit, and a cancellation determination section. The preceding vehicle position storage unit chronologically stores a preceding vehicle position, which is a position of a preceding vehicle traveling ahead of the own vehicle. The predicted course computation unit calculates a predicted course, based on the trajectory of the preceding vehicle position. The cancellation determination section cancels the preceding vehicle position stored in the preceding vehicle position storage unit when it has been determined that either the own vehicle or the preceding vehicle is in a situation where the own vehicle or the preceding vehicle is likely to depart from the current course.

  • Publication number: 20170328810
    Abstract: An electronic control unit diagnoses leakage abnormality in an intake system downstream from a supercharger provided in the intake system of the engine. The electronic control unit sets, as a supercharging region monitoring value, a ratio between a first air amount obtained from a detection value of an air flowmeter and a second air amount obtained from a detection value of an intake pressure sensor, the ratio being the ratio obtained when the engine is operated in a supercharging region. The electronic control unit also sets, as a non-supercharging region monitoring value, a ratio obtained when the engine is driven in a non-supercharging region. The electronic control unit determines the presence of the leakage abnormality in the intake system when the ratio of the supercharging region monitoring value to the non-supercharging region monitoring value is larger than a predetermined specified value.

  • Publication number: 20170328288
    Abstract: A control device estimates a leakage gas amount with respect to gas that leaks to an upstream side from a downstream side of a fresh air introduction valve when the fresh air introduction valve is closed. If the leakage gas amount is equal to or greater than a predetermined value when there is a request to open the fresh air introduction valve, a target opening degree of the fresh air introduction valve is determined based on the engine speed and intake pressure, and also a correction opening degree with respect to the target opening degree is calculated based on the leakage gas amount. The fresh air introduction valve is opened to an opening degree greater than the target opening degree by an amount corresponding to the correction opening degree, to thereby cause leakage gas that is accumulated in a fresh air introduction passage to flow into an intake passage together with a required amount of fresh air.

  • Publication number: 20170327118
    Abstract: A cruise control apparatus controls the traveling of an own vehicle on the basis of the predicted route which is a predicted value of the travel route of an own vehicle. The cruise control apparatus compares the moving locus of the preceding vehicle with the position of a stationary object provided along the road to determine whether or not a moving locus is along the shape of the road. The moving locus is validated when it is determined that the moving locus is along the shape of the road, and the moving locus is invalidated when it is determined that the moving locus is not along the shape of the road, and the predicted route of the vehicle is calculated on the basis of the validated moving locus.
