  • Patent number: 10922561
    Abstract: An object recognition device installed on a vehicle includes a first camera detecting a first object, a second camera detecting a second object, a ranging sensor detecting a third object, and a controller. The controller sets first to third determination ranges with respect to detected positions of the first to third objects, respectively, and executes fusion processing by comparing the determination ranges. First and second pixel densities being pixel densities of the first and second objects are determined based on detected distances of the first and second objects, angles of view and numbers of pixels of the first and second cameras, respectively. The controller sets the first determination range larger as the first pixel density is lower, and sets the second determination range larger as the second pixel density is lower.

  • Publication number: 20200346645
    Abstract: A control device for a vehicle includes a camera sensor and an ECU. The ECU defines a specified area based on a position of a stationary object when the recognized objects include the stationary object. The ECU performs first driving support for reducing a possibility of a collision between a moving body and the host vehicle when the recognized objects include the moving body which is positioned within the specified area. Boundary lines partitioning the specified area include a first traveling direction boundary line extending in a traveling direction of the host vehicle. An inside of the specified area is a side on which the stationary object is positioned with respect to the first traveling direction boundary line. The first traveling direction boundary line is set on a side opposite to the stationary object across a reference line set based on a predicted course of the host vehicle.

  • Publication number: 20200241539
    Abstract: A control device includes an electronic control unit executes steering control for avoiding a collision with an object that has a possibility of colliding with a host vehicle. The electronic control unit sets a timing when the host vehicle is predicted to pass the object as an end timing of the steering control when the steering control is performed. The electronic control unit determines whether or not a deviation possibility is present when the electronic control unit assumes that the steering control ends at the end timing. The deviation possibility is a possibility of the host vehicle deviating from a current traveling lane accompanying an end of the steering control. The electronic control unit performs reduction processing that reduces the deviation possibility when the electronic control unit determines that the deviation possibility is present.
