  • Publication number: 20240048853
    Abstract: Provided are example systems for obtaining optical sensor data to facilitate the operation of an autonomous vehicle. In an example implementation, a system includes a light source, an optical sensor, and a control module. The light source periodically emits pulses of light into the environment of the autonomous vehicle. The optical sensor periodically obtains optical sensor data of the environment of the autonomous vehicle. The control module obtains additional sensor data from one or more additional sensors, the additional sensor data representing at least one of a characteristic of the autonomous vehicle or a characteristic of the environment of the autonomous vehicle, and controls an operation of the light source based on the additional sensor data.

  • Publication number: 20230303113
    Abstract: Provided are methods, systems, and computer program products for lane keep tracking and/or localization of a vehicle using a radar to detect metallic particles in paint applied to lane markings or curb markings. An example method may include: causing a radar system of a vehicle to output radio waves; receiving a radar image from the radar system corresponding to returned radio waves; determining a portion of the radar image includes lane or curb markings, wherein the lane or curb markings are embedded with metallic particles; and determining a location of the vehicle based at least in part on the determined portion of the radar image that includes the lane or curb markings.
