  • Patent number: 10668919
    Abstract: An object detection apparatus acquires a lateral position which is a relative position of a target to the own vehicle, and determines that a first target is present, as the target, ahead of the own vehicle and that a second target is present between the first target and the own vehicle. The object detection apparatus determines, based on the lateral position of the first target and a limiting value which indicates a width in the lateral direction, whether the first target is present on a traveling course of the own vehicle. The object detection apparatus sets the limiting value such that when the second target is not present, sets as the limiting value, a predetermined reference value, and when the second target is present, sets as the limiting value, a value different from the reference value.

  • Patent number: 10625739
    Abstract: A vehicle control apparatus accumulates a history of timings of avoidance operations performed by a driver of with respect to objects that are at prescribed distances ahead of a host vehicle, and calculates a distribution of the timings of the avoidance operations. Based on the distribution of the timings of the avoidance operations, the vehicle control apparatus sets the output timing of a warning to the driver such that interference does not occur between the avoidance operation and an avoidance operation that is actually performed by the driver, and furthermore the vehicle control apparatus judges the risk of a collision with the host vehicle, with the judgement based on the position of an object that is ahead of the host vehicle, and changes the output timing of the warning based on results of the judgement of risk.

  • Patent number: 10573180
    Abstract: A vehicle control device generates a fusion target by fusion of a radar target of an object ahead of the own vehicle acquired as a reflected wave of a carrier wave and an image target of the object acquired by image processing of an acquired image of a region ahead of the own vehicle and performs vehicle control of the own vehicle for the object detected as the fusion target. The vehicle control device determines whether a state where the object is detected with the fusion target has transitioned to a state where the object is detected with only the radar target; determines whether a distance to the object is a predetermined short distance when the state is determined to have transitioned to the state where the object is detected with only the radar target; and performs the vehicle control for to the object when the distance to the object is determined to be the predetermined short distance.

  • Patent number: 10395820
    Abstract: A common mode choke coil according to one embodiment of the present invention includes a first coil conductor, a second coil conductor, and a third coil conductor. In the embodiment, the second coil conductor has a different shape than the first coil conductor and the third coil conductor. In the embodiment, the first coil conductor, the second coil conductor, and the third coil conductor extend parallel with each other in a first region in plan view as seen from an axial direction along the coil axis. In the embodiment, in the first region, when seen in a cross section cut along a plane including the coil axis, in an n-th turn, an arranging order of the first coil conductor, the second coil conductor, and the third coil conductor from an inner side in a radial direction thereof is inverted from that in an n+1th turn.

  • Publication number: 20180118202
    Abstract: A vehicle control apparatus acquires a relative position of an object to an own vehicle, the object being located ahead of the own vehicle in a traveling direction. The vehicle control apparatus acquires yaw rate information including at least one value of a yaw rate and a yaw rate differential value of the own vehicle. The vehicle control apparatus acquires steering information including at least one value of a steering angle and a steering angle speed of the own vehicle. The vehicle control apparatus activates, on a basis of the relative position, a safety unit for avoiding a collision with the object. In the case where an absolute value of the yaw rate information is greater than a first threshold and an absolute value of the steering information is greater than a second threshold, the vehicle control apparatus causes the safety unit to be less likely to be activated.
