Method for monitoring a lane change of a vehicle

A non-transitory computer-readable medium on which is stored a computer program including commands for monitoring a lane change of a vehicle, the commands, when executed by a computer, causing the computer to perform the following steps:

• ascertaining a collision point based on a movement specification, wherein the movement specification is specific for a planned movement of the vehicle along a path for carrying out the lane change;
• checking for a possible collision of the vehicle with a road user based on the ascertained collision point and at least one state parameter of the vehicle;
• determining an adjustment specification to avoid the possible collision, wherein the adjustment specification includes a calculated acceleration behavior of the vehicle;
• and
• providing the adjustment specification to monitor the lane change, wherein a trajectory for a collision-free lane change is determined based on the adjustment specification, and wherein determining the trajectory comprises:
• calculating average accelerations required to perform the collision-free lane change,
• checking if the calculated average accelerations exceed predefined maximum acceleration limits, and
• if the maximum acceleration limits are exceeded, saturating the calculated average accelerations to the maximum acceleration limits and recalculating a maneuver time for the trajectory based on the saturated accelerations.
