A driving support apparatus for an own vehicle includes a lane keeping assist control unit. When an interrupting vehicle enters ahead of the own vehicle in (i) a situation in which no preceding vehicle is present ahead of the own vehicle, or (ii) a situation in which a preceding vehicle is present ahead of the own vehicle, while a deviation angle formed between a direction of a traveling trajectory of the interrupting vehicle and a traveling direction of the own vehicle is larger than a threshold, the lane keeping assist control unit is configured not to perform a lane keeping assist control based on the traveling trajectory of the interrupting vehicle, and is configured to discard the traveling trajectory of the interrupting vehicle. On and after the deviation angle becomes equal to or smaller than the threshold, the lane keeping assist control unit is configured to perform the lane keeping assist control based on the traveling trajectory of the interrupting vehicle.

Driving aid control apparatus
11117615 · 2021-09-14 · ·

An apparatus for performing driving aid control to cause a travel trajectory of a mobile object to follow a setpoint trajectory (La) by transmitting a control command value (δ) to a yaw moment controller capable of controlling a yaw moment of the mobile object. In the apparatus, a setpoint trajectory setter is configured to set the setpoint trajectory (La) of the mobile object. A control command value calculator is configured to calculate the control command value (δ) based on an integrated value (δI) of a lateral error that is an error between a position of the mobile object and the setpoint trajectory. The control command value calculator is further configured to decrease the integrated value (δI) with decreasing a curvature (ρ) of a road on which the mobile object is traveling.

Driving scene based path planning for autonomous driving vehicles
11003183 · 2021-05-11 · ·

According to one aspect, a set of driving scenes are defined including, but are not limited to, a driving straight scene, a turning scene, a nudge scene, and a lane changing scene. For each of the predefined driving scenes, a list of path segments corresponding to a set of one or more features (e.g., speed, curvature, turning radius, relative distance, lane width, etc.) are determined based on the driving statistics of a number of vehicles driving through the same or similar driving scenes (e.g., driving straight, making turns, changing lanes, nudging obstacles or another vehicle) in the past. The path segments are then stored in a driving scene-to-path (scene/path) data structure specifically configured for the corresponding driving scene. For example, there will be at least one scene/path data structure for each of the driving straight scene, turning scene, nudge scene, and lane changing scene.

Apparatus for identifying line marking on road surface

An apparatus for identifying a line marking on a road surface. In the apparatus, an extractor extracts a paint candidate that is a candidate for road surface paint used to identify a line marking in an image captured by a camera mounted on a vehicle to capture an image of an area including a road surface ahead of the vehicle. A determiner determines whether or not the paint candidate has at least one predefined flare feature. A line marking identifier identifies a line marking using the paint candidate which meets an identification condition used to identify a line marking. The line marking identifier sets the identification condition to be more stringent for a flare paint candidate that is the paint candidate determined by the determiner to have the at least one predefined flare feature than for the paint candidate determined by the determiner to have no predefined flare feature.
