  • Patent number: 11414053
    Abstract: Disclosed is a vehicle wiper control device which includes: wiper blades that can be disposed on a surface to be wiped and that perform a reciprocating wiping motion between a lower reversal position and an upper reversal position which are set on the surface to be wiped; an electric motor that reciprocates the wiper blades on the surface to be wiped; a drive portion that drives the electric motor; and a load calculation portion that calculates a load on the electric motor while the wiper blades wipe from the upper reversal position to the lower reversal position. If the calculated load value exceeds a predetermined threshold, the drive portion performs wiper stop processing for stopping the wiper blades at the lower reversal position or at a storage position which is set below the lower reversal position.

  • Patent number: 11393128
    Abstract: An adhered substance detection apparatus of an embodiment includes a calculator and a determiner. The calculator calculates an edge feature for each cell based on edge vectors of pixels within the cell in a captured image, and further calculates a region feature for each unit region based on the calculated edge features of the cells within the unit region. The determiner determines an adherence state of an adhered substance on a lens of a camera based on the region feature. The calculator calculates, as the region feature, number of the cells having an edge strength of zero. When the number of the cells having the zero edge strength is equal to or greater than a predetermined number in a predetermined attention area in the captured image, the determiner determines not to perform a determination for detecting whether the lens of the camera is entirely covered by the adhered substance.

  • Publication number: 20220203970
    Abstract: A vehicle control apparatus includes a braking controller individually controlling braking forces of braking devices for left and right front and rear wheels, a side collision detector detecting a side collision against a vehicle, and a yaw behavior detector detecting yaw behavior of a vehicle body. If the yaw behavior detected after the side collision is such that a rear of the vehicle body shifts away from a collision side relative to a front thereof, the braking controller executes yaw amplification control to cause the braking device for the collision-side front wheel to generate a braking force larger than the remaining wheels. If the detected yaw behavior is such that the front shifts away from the collision side relative to the rear, the braking controller executes the yaw amplification control to cause the braking device for the collision-side rear wheel to generate a braking force larger than the remaining wheels.

    Abstract: A vehicle controller includes a collision detector, a braking controller, a motional state detector, and a minor collision determiner. The collision detector is configured to detect a collision between a vehicle and another object. The braking controller is configured to cause a braking device of the vehicle to generate a braking force in accordance with the detecting of the collision by the collision detector. The motional state detector is configured to detect a motional state of the vehicle. The minor collision determiner is configured to determine, based on an output from the motional state detector, that a minor collision occurs that is a collision not detected by the collision detector. The braking controller is configured to cause the braking device to generate the braking force if the collision detector does not detect the collision and the minor collision determiner determines that the minor collision occurs.
