  • Publication number: 20240092337
    Abstract: A vehicle control apparatus includes front-wheel and rear-wheel driving systems, and a control system. The front-wheel driving system includes a first travel motor mechanically coupled to a front wheel of a vehicle and a first accumulator electrically coupled to the first travel motor. The rear-wheel driving system includes a second travel motor mechanically coupled to a rear wheel of the vehicle and a second accumulator electrically coupled to the second travel motor. The control system includes one or more processors and one or more memories communicably coupled to the one or more processors, and controls the first and second travel motors. When a difference between an SOC of the first accumulator and an SOC of the second accumulator is greater than a threshold value, the one or more processors change a torque distribution ratio between the first and second travel motors from a reference distribution ratio.

  • Publication number: 20230229069
    Abstract: The light source unit includes a base provided with an opening, a support member fixed to the base at the opening, and a light source assembly fixed to the support member at the opening. The light source assembly includes a light source emitting laser light, a lens disposed on an optical axis of the laser light, and a holding member holding the light source and the lens. The support member has a convex receiving surface extending along the spherical surface so as to surround the optical axis when viewed from a direction parallel to the optical axis. The light source assembly is fixed to the support member by coupling the holding member to the receiving surface at a contact portion with the receiving surface. The receiving surface has a portion located on a side away from the optical axis with respect to a coupling part with the holding member.

  • Patent number: 11340447
    Abstract: A display device includes: a light source unit that outputs laser light; a light-guide optical system that forms a plurality of optical paths of the laser light; an optical path switch element that switches an optical path of the laser light to any one of the plurality of optical paths; an optical member that forms a single optical path in a subsequent stage of the plurality of optical paths; and a projection mirror that forms a projection image to be projected on a screen by scanning the laser light that passed through the single optical path. The plurality of optical paths includes an optical path for low luminance and an optical path for high luminance which make the laser light have different luminance. The optical path switch element is disposed on an optical path between the light source unit and the projection mirror.

  • Patent number: 10928716
    Abstract: A projection display device includes: a light source that emits a first laser light for displaying a projection and a second laser light for inspection; a scanning drive mirror that reflects the first laser light and the second laser light emitted from the light source, and uses the first laser light and the second laser light in scanning; a light diffusion unit that allows the first laser light used in the scanning by the scanning drive mirror to be transmitted through the light diffusion unit and diffuses the first laser light; a light selection unit that allows the first laser light to be transmitted through the light selection unit and reflects the second laser light at a position on an emission surface of the light diffusion unit; and a light detection unit that detects the second laser light reflected by the light selection unit.

  • Patent number: 10197895
    Abstract: A projection display device includes: a light source that emits a first and a second laser lights; a scanning drive mirror that reflects the first and the second laser lights, and uses the first and the second laser lights in scanning; a light diffusion unit that includes a predetermined region that allows the first laser light to be transmitted therethrough, and diffuses the first laser light; a light detection unit that detects the second laser light that passed the predetermined region; and a control unit that executes a process to detect the second laser light, and determines a state of the predetermined region on the basis of a detection value of the light detection unit. In a case where the control unit determines that a defect occurs in the predetermined region as the state, the control unit executes a process to stop displaying the projection.
