  • Publication number: 20220255473
    Abstract: A first actuator and a second actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. In the first and the second actuators, the control calculation units of the systems paired with each other transmit and receive information to and from each other by a communication between the actuators. When a failure occurs in any system in either of the two actuators, or when a failure occurs in a communication between actuators in either system, the control calculation unit of each actuator of the system in which the failure occurred stops the motor drive control. Then, the motor drive control is continued by the control calculation unit of the normal system in both actuators.

  • Publication number: 20220205610
    Abstract: A vehicle headlamp includes a reflector having plural reflecting surfaces arranged in a left-right direction, and n light sources which are arranged in the left-right direction and emit light toward any one of the reflecting surfaces. At least two adjacent light sources are provided as a common light source which emits light toward a same reflecting surface. n illumination patterns which illuminate different regions in the left-right direction are formed by light emitted from the n light sources, respectively, and are taken as a first to n-th illumination patterns in this order in the left-right direction. At least half of areas of illumination patterns of an immediately-following number and an immediately-preceding number overlap each other in the left-right direction. Focal lengths of the plural reflecting surfaces are set such that adjacent illumination patterns which do not overlap each other are formed by light emitted from the common light source.
