  • Patent number: 12246684
    Abstract: A vehicle cleaner system includes a cleaner unit discharges a cleaning fluid toward a cleaning target mounted on a vehicle; a motor pump supplies the cleaning fluid to the cleaner unit; a normally closed type solenoid valve provided between the cleaner unit and the motor pump and switches between permission and non-permission of movement of the cleaning fluid from the motor pump to the cleaner unit; and a cleaner control unit controls the motor pump and the solenoid valve. The cleaner control unit sets an operation stop time period for stopping an operation of at least one of the motor pump and the solenoid valve, and after the cleaning fluid is discharged to the cleaning target, stops the operation of at least one of the motor pump and the solenoid valve during the operation stop time period based on a predetermined condition.

  • Publication number: 20240294111
    Abstract: A high-definition lamp unit contains a plurality of individually controllable pixels, and emits lamp beam having light distribution corresponding to states of the pixels. A first sensor is provided to enable detection of a dynamic component of a pitch angle of a traveling vehicle body. A controller shifts the level of a cut-off line CL of the light distribution up and down, corresponding to the dynamic component of the pitch angle of the vehicle body, with reference to a predetermined level defined as a base.

  • Publication number: 20240109474
    Abstract: A light distribution control device, if a first upper limit number N1?the number of near-distance targets T1, controls a lamp to irradiate the near-distance targets with light having illuminance according to attributes of the near-distance targets; if a remaining number M?the number of long-distance targets T2, controls the lamp to irradiate the long-distance targets with light having illuminance according to attributes of the long-distance targets; if N1<T1, controls the lamp to form a light distribution pattern that does not depend on the near-distance targets and the long-distance targets; and, if M<T2, controls the lamp to form a light distribution pattern that does not depend on the long-distance targets.
