A system for adjusting a road boundary of a two dimensional virtual representation of a road for path planning of an autonomous vehicle includes a retrieval unit to retrieve a measured position and measured heading angle of the vehicle with respect to a reference. The system also includes an uncertainty unit to receive the measured position, the measured heading angle and map data of the road, and to determine a position uncertainty value and a heading angle uncertainty value representing an amount of uncertainty in the vehicle position and heading angle, respectively, on the road based on the input. The system also includes an adjustment unit to adjust a width and a heading angle of a drivable portion of the two dimensional virtual representation of the road, wherein the adjustment of the width and heading angle is based on the position uncertainty value and the heading angle uncertainty value, respectively.

System and method for adjusting a road boundary

An onboard perception system of a vehicle is contemplated. The system may include a state assessment unit adapted to at least assess a state of a first external object located in a vicinity of the vehicle hosting the onboard perception system, at least a first sensor assembly for assessing sound information, and an evaluation means adapted to evaluate a change in the state of the first external object by using the assessed sound information.

Onboard perception system

A method for reducing the risk of a collision between a vehicle and at least a first external object is contemplated. The risk of a collision may be reduced with use of a collision avoidance system having a detection unit adapted to issue a control signal in the event it detects a collision involving a first external object in a vicinity of the host vehicle, and an action unit adapted to operate the collision avoidance system such that an emergency maneuver can be initiated by the collision avoidance system at an earlier stage if the control signal is issued, as compared to when no control signal is issued.
