  • Patent number: 12077187
    Abstract: A sensing system provided in a vehicle capable of running in an autonomous driving mode, includes: a LiDAR unit configured to acquire point group data indicating surrounding environment of the vehicle; and a LiDAR control module configured to identify information associated with a target object existing around the vehicle, based on the point group data acquired from the LiDAR unit. The LiDAR control module is configured to control the LiDAR unit so as to increase a scanning resolution of the LiDAR unit in a first angular area in a detection area of the LiDAR unit, wherein the first angular area is an area where the target object exists.

  • Publication number: 20240239308
    Abstract: A vehicle cleaner system includes a sensor, a cleaner, a vehicle control unit, and a cleaner control unit. The sensor is mounted on a vehicle, and is configured to acquire information around the vehicle, and is configured to output a sensor signal. The cleaner is capable of discharging a cleaning liquid to the sensors. The vehicle control unit is configured to recognize information around a host vehicle or control the host vehicle by using the sensor signal output from the sensor. The cleaner control unit is configured to output to at least one of the sensor and the vehicle control unit an in-operation signal indicating that the cleaner is in operation when the cleaner is in operation.

  • Publication number: 20220113427
    Abstract: Provided is a LiDAR sensor unit in which even when a lens element is provided, measurement data is less likely to be affected by the lens element. A LiDAR sensor unit has: a LiDAR sensor; a lens element that is provided on an optical path of light emitted from the LiDAR sensor; and a processing unit that outputs measurement data which has been measured by the LiDAR sensor and which includes the orientation and the distance of a measurement subject. The processing unit is configured to not output measurement data of a specific orientation which is the same but the distance corresponding thereto differs before and after attachment of the lens element under the same environment.

  • Publication number: 20210341354
    Abstract: A sensor system (100) is equipped with a light emitting element that emits detecting light (L1), a translucent cover (120) that allows passage of the detecting light (L1), and a scanning mechanism that changes an emitting direction of the detecting light (L1) at least in a first direction (D1). A light receiving device (210) is equipped with a plurality of inspection light receiving elements (211a to 211g) arranged at least along the first direction, and adapted to be disposed on an optical path of the detecting light (L1) that has passed through the translucent cover (120). An inspection processor (220) is configured to output a determination result (R) as to whether an abnormality is present in the translucent cover (120) on the basis of a determination as to whether each of the inspection light receiving elements (211a to 211g) has normally received the detecting light (L).
