  • Patent number: 9273592
    Abstract: A hybrid vehicle includes: an internal combustion engine having an in-cylinder injection valve directly injecting fuel into a combustion chamber and a port injection valve injecting fuel into an intake port; and a motor generator, and causes a torque equal to a user required torque to act on a drive shaft by controlling output torques of the engine and motor generator. When a misfire is not detected, the hybrid vehicle operates the engine at an engine operation point at which an engine power satisfies an engine required power in a first engine operation line. When a misfire is detected, the hybrid vehicle operates the engine at an engine operation point at which the engine power satisfies the engine required power in a second engine operation line, causes one of the injection valves to inject an entire amount of fuel, and determines which one is abnormal.

  • Patent number: 9266523
    Abstract: Disclosed is a vehicle control apparatus that can concurrently achieve an improved drivability and an excellent restart performance of an internal combustion engine. The vehicle control apparatus includes an eco-run system that automatically stops the engine when an automatic stop condition is established and restarts the engine when a restart condition is established, a throttle motor that opens and closes a throttle valve adjusting air amount to be sucked into the engine, and a vehicle speed sensor that detects the vehicle speed. The vehicle control apparatus is adapted to control the throttle motor to enlarge the throttle valve opening degree in response to the higher vehicle speed, according to the vehicle speed information from the vehicle speed sensor (Step S3 to Step S7), when the engine is automatically stopped while the vehicle is travelling (Step S2).

  • Patent number: 9266534
    Abstract: A vehicle control apparatus for implementing inter-vehicle distance control of a subject vehicle carrying the apparatus behind a preceding vehicle based on reflected waves from a target of the preceding vehicle. A target-pair distance is a distance between the target and a non-target reflection point that is closer to the subject vehicle than the target. A corrected distance calculator is configured to, in the presence of the target-pair distance being recognized, calculate a first corrected distance by subtracting the target-pair distance from a detected distance between the target and the subject vehicle, and in the absence of the target-pair distance being recognized, calculate a second corrected distance by subtracting an offset that is the previously set target-pair distance from the detected distance. A controller is configured to implement the inter-vehicle distance control based on the first or second corrected distance depending on the presence or absence of the target-pair distance being recognized.

  • Patent number: 9262924
    Abstract: A human machine interface (HMI) can communicate warnings and messages to a driver by selecting among a variety of warning devices based on information related to the driver's viewing angle. The variety of warning devices can include a primary-visual warning device (e.g., a heads up display), secondary-visual warning devices (e.g., an instrument cluster or a navigational screen), a portable device (e.g., a tablet or a cellular phone), an audio system, or a haptic device. The HMI apparatus displays warnings on visual warning devices within the driver's view, can signal an active portable device to output a warning. Visual warnings can include directional cues. Audio warnings may accompany the visual warnings, and can be output with greater intensity when no visual devices are within the driver's view.
