  • Publication number: 20240101021
    Abstract: A headlight determination apparatus includes a camera device, a target light recognition device, and a changing device. The camera device captures an image ahead of a vehicle at a predetermined frame rate. The target light recognition device recognizes target light from the image captured by the camera device. The changing device changes a wavelength of headlight of the vehicle by using a predetermined period slower than the predetermined frame rate. When the wavelength of the headlight is different from a wavelength of the target light and/or when a period of the wavelength of the headlight does not match a period of the wavelength of the target light, the target light recognition device recognizes that there is target light other than the headlight in front of the vehicle and controls light distribution of the headlight when there is target light other than the headlight in front of the vehicle.

  • Patent number: 11052904
    Abstract: When starting a skip downshift, a controller for an automatic transmission disengages two or more engagement elements that are in an engaged state. The disengaging two or more engagement elements includes setting a first engagement element, which is one of the two or more engagement elements that are disengaged and is used to form an intermediate gear stage having a lower transmission ratio than a post-shifting gear stage, to an engagement preparation state that maintains a state immediately before the engaged state. Subsequently, the controller engages a second engagement element, which is used to form both the intermediate gear stage and the post-shifting gear stage, and temporarily increases engagement pressure of the first engagement element. The controller disengages the first engagement element and engages a third engagement element, which is used to form the post-shifting gear stage, to form the post-shifting gear stage.
