  • 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.

  • Publication number: 20170326981
    Abstract: A cruise control apparatus, mounted to a vehicle, controls traveling of the own vehicle, based on a predicted course, which is a future course of the own vehicle. 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: 20170330033
    Abstract: Provided is an object detection device (13) using a detection means (11) to transmit probe waves, receive reflected waves from an object (50) in a detection range, and acquire, as first detection information on the object, a position based on the reflected waves, to detect the object. The device includes an image information acquisition means, determination region setting means, and an object locating means. The image information acquisition means acquires, as second detection information on the object, a position based on an image of an area within the detection range, the image being captured by an image capturing means (12). The determination region setting means sets a determination region in the detection range. The object locating means locates the object, based on the first detection information, if pieces of the first and second detection information are present in the determination region.

  • Publication number: 20170270373
    Abstract: A road shape recognition apparatus is mounted in a vehicle. The road shape recognition apparatus acquires a road image, determines a road shape using the road image, recognizes the road shape based on the road image within a predetermined recognition range, and estimates the road shape outside of the recognition range based on the road shape within the recognition range. The road shape recognition apparatus estimates the road shape outside of the recognition range and within a first distance as a curved line of which a curvature change rate is constant, and the road shape farther than the first distance as a curved line of which a curvature is constant.

  • Patent number: 7119532
    Abstract: A magnetic rotation detector includes a magnetic rotor having magnetic bodies, a detecting body that detects a change in magnetic flux that is caused by the magnetic bodies as the magnetic rotor rotates; and an abnormality determination portion that monitors an apparent fluctuation in rotational speed of the magnetic rotor based on a result detected by the detecting body and that determines that the magnetic rotor is in an abnormal state if the fluctuation occurs at a specific position of the magnetic rotor. The abnormality determination portion detects the occurrence of the fluctuation at the specific position of the magnetic rotor by making a determination on a distance between apparent positions of the magnetic bodies which correspond to the apparent fluctuation in rotational speed and calculates the distance on the basis of a product of an interval of generation of noise in an output signal detected by the detecting body and a rotational speed of the magnetic rotor at the time of generation of noise.

  • Patent number: 7092829
    Abstract: In an instantaneous wire interruption detection system for a vehicle electrical system, a VSC-ECU includes an input processing circuit that processes electric signals transmitted from various sensors and an EFI-ECU by a signal wire (wire harness); a signal state determination circuit that determines whether the electric signals processed by the input processing circuit are normal or abnormal; a latch circuit that latches the determination result as a latch signal; and an output circuit that can output the latch signal. When a signal abnormality is detected by the signal state determination circuit, the latch circuit is able to generate the latch signal in synchronization therewith, and latch the latch signal for a predetermined time. Accordingly, for example, by connecting a tester device to the output circuit, and monitoring the latch signal, it is possible to detect instantaneous wire interruption of the electrical system.

  • Patent number: 7082357
    Abstract: When a resistance value of a CAN bus main line is 60 ?, the CAN bus main line is in a normal state. However, the resistance value thereof differs depending on an abnormality portion when an abnormality such as disconnection, short circuit, or the like has occurred in it or a branch line. Therefore, the abnormality portion can be identified depending on the measured resistance value. In addition, a failure diagnosis portion of an ECU stores different diagnosis trouble codes in the memory for the following cases; when an abnormality has occurred in the CAN bus communication, when various sensors are malfunctioning, and when an abnormality such as disconnection has occurred in a communication line that is connected to the various sensors. Accordingly, the resistance value of the CAN bus main line is measured, and the abnormality portion can be identified by a combination of the resistance value and the diagnosis trouble code.

  • Publication number: 20040263160
    Abstract: As a magnetic rotor rotates, magnets disposed on an outer periphery of the magnetic rotor move, whereby a change in magnetic flux around a pick-up is caused. The pick-up then outputs a signal. If the signal output from the pick-up fluctuates due to a certain one of the magnets which is located at a specific position on the magnetic rotor, it is determined that the magnetic rotor is in an abnormal state such as adhesion of iron fragments to the magnets or the like.
