Publication number: 20220371620Abstract: A path planning device configured to plan a traveling path on a future route of a vehicle includes a lane evaluation unit, a score accumulation unit, and a lane selection unit. The lane evaluation unit is configured to estimate a risk score of each chronological section of each traveling lane parallel traveling lanes, the risk score representing a traveling risk. The score accumulation unit is configured to accumulate the risk scores for each traveling lane. The lane selection unit is configured to select the traveling lane for the traveling path based on evaluation accumulated values. The lane evaluation unit is configured to estimate a base score based on static information. The static information contains a traveling difficulty for the vehicle at a change node. The lane evaluation unit is configured to estimate the base score such that the traveling risk is higher as the traveling difficulty is higher.Type: ApplicationFiled: August 1, 2022Publication date: November 24, 2022Inventor: KOUJI KAWAKITA

The determination unit is configured to determine whether a second vehicle different from the first vehicle is present in the branch lane. The adjustment unit is configured to adjust a sharpness of the branch trajectory based. The branch trajectory in a scene where it is determined that the second vehicle is present in the branch lane is a branch following trajectory. The branch trajectory in a scene where it is determined that the second vehicle is not present in the branch lane is a branch release trajectory. The branch release trajectory guides the first vehicle to the branch lane less sharply than the branch following trajectory.Type: ApplicationFiled: July 25, 2022Publication date: November 10, 2022Inventors: KOUJI KAWAKITA, KEIGO FUJIMOTO
