  • Patent number: 11973453
    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: 20240132147
    Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

  • Patent number: 10295152
    Abstract: A light emitting diode lamp is composed of a light emitting diode, a band-pass filter and a light angle adjuster. The filter has a light cutoff function to cut off a light ray with a specific wavelength. The light angle adjuster allows the light rays emitted from the diode to be incident on the filter at incident angles of less than or equal to a maximum incident angle up to which the filter is capable of exerting the light cutoff function. The light angle adjuster is a reflector. The diode is mounted to a bottom portion. The filter is mounted to an opening. On an imaginary cross section including the optical axis, an angle formed between the optical axis and a straight line is less than or equal to the maximum incident angle, the straight line connects the emission center and an edge of the opening.
