Control system for autonomous vehicle lane change safety
The granted patent (Publication Number: US11999350B2) discloses a control system for a host vehicle operating in autonomous mode. The system includes controllers that determine the need for the vehicle to move from one lane to another for overtaking. It checks for conditions in adjacent lanes to ensure safety before executing the maneuver. If conditions are not met, the vehicle remains in its current lane. The system also includes electronic processors and memory devices to facilitate these operations.
Additionally, the control system can check for a second abort condition related to the presence of other road users in the target lane. If both abort conditions are not met, the vehicle completes the overtaking maneuver. The system is designed to increase separation from the vehicle being overtaken, accelerate towards it, and then move into the overtaking lane. The amount of separation and acceleration is determined by various factors such as vehicle speed, presence of other road users, and infrastructure. The patent also covers a method for controlling the vehicle, a vehicle equipped with the control system, and computer software and storage mediums to execute the described method.
