20190359202 · 2019-11-28 ·

In one embodiment, during a planning stage of autonomous driving of an autonomous driving vehicle (ADV), it is determined that the ADV needs to change lanes from a source lane to a target lane. A first trajectory is generated from a current location of the ADV in the source lane to the target lane such as a center line of the target lane. A lane shifting correction is then calculated based on the lane configuration of at least the source lane and/or target lane, as well as the current state of the ADV. Based on the lane shifting correction, at least the starting point of the first trajectory is modified, which in turn generates a second trajectory. In one embodiment, the starting point of the first trajectory is shifted laterally with respect to a heading direction of the source lane based on the lane shifting correction.

Driving support apparatus

A driving support apparatus includes an other vehicle detector, an other vehicle information acquisition unit, a proximity detector, a proximity controller and a setting unit. The other vehicle detector detects an other vehicle travelling on the second lane. The other vehicle information acquisition unit acquires information containing the size of the other vehicle. The proximity detector outputs a proximity signal when it is detected that the other vehicle is located in the detection range of set on the second lane at a predetermined detection distance from the own vehicle. The proximity controller activates a proximity control unit when detecting that a turn signal lever is operated while the proximity signal is being output. The setting unit increases the detection distance according to the size of the other vehicle.

Lane keeping system for autonomous vehicle in wind conditions

A lane keeping system includes an absolute pressure sensor located in a door on each of opposing sides of a vehicle. Each sensor generates a signal indicative of a door cavity pressure on that side of the vehicle. A safety restraint system (SRS) controller is in communication with the pressure sensor. The SRS controller is configured to determine a collision event in response to the signal (e.g., increased pressure in the door as it is crushed) and activate a safety restraint component in response to the determined collision event. A lane keeping system (LKS) controller is in communication with the pressure sensors. The LKS controller determines a lateral wind force on the vehicle in response to the signal from each pressure sensor. The LKS controller determines a correction in response to the determined lateral wind force to maintain the vehicle along a desired path.
