  • Patent number: 12322191
    Abstract: The disclosure relates to a lane line determination method and system, a vehicle, and a storage medium, and the lane line determination method includes: capturing a road image for a current location in a vehicle coordinate system; recognizing the road image and generating basic lane lines for the current location; extracting map lane lines for the current location; mapping the map lane lines to the vehicle coordinate system to obtain auxiliary lane lines; registering the basic lane lines with the auxiliary lane lines, the registration being performed based on confidence levels of the basic lane lines; and generating target lane lines based on the registered auxiliary lane lines and the basic lane lines. According to the lane line determination method, an operation such as correction can be performed, according to a condition, on a visually captured lane line by using a map lane line, thereby improving accuracy of the lane line detection.

  • Patent number: 12162487
    Abstract: The disclosure relates to a vehicle velocity control method. The method includes: determining, by an onboard sensor, drivable distances in different directions in front of a current vehicle, and obtaining, at least based on types of targets in the different directions, an area of a drivable space in front of the current vehicle; determining, based on the area of the drivable space and a current vehicle velocity, a result of a safety degree in a current driving scenario; and controlling the vehicle velocity of the current vehicle based on the result of the safety degree. The disclosure further relates to a vehicle control device, a computer storage medium, and a vehicle.

  • Publication number: 20230126696
    Abstract: The disclosure relates to a lane change method and system, a storage medium, and a vehicle. The lane change method includes the following steps: receiving consecutive frames of condition information, the condition information including velocity information of a current vehicle, state information of an adjacent vehicle, and lane information; with the condition information as an input to a neural network, processing the condition information by means of the neural network, to obtain an initial lane change strategy; and correcting the initial lane change strategy based on a predetermined rule and the condition information, to generate and output a corrected lane change strategy. According to this lane change method, intelligent, safe and efficient lane change may be achieved during an autonomous driving or driving assistance process.
