Method and system for post-collision manoeuvre planning and vehicle equipped with such system
First Claim
1. A method for assisting a driver of a host vehicle, the host vehicle comprising a data acquisition means and a processing means, the method comprising steps of:
- acquiring data describing a traffic environment by the data acquisition means; and
processing, with the processing means, the data describing the traffic environment to generate crash determination information indicating a probability of a crash in the traffic environment;
determining, based on the crash determination information, whether a crash situation involving at least one target object will occur, wherein the at least one target object is a traffic participant;
when occurrence of the crash situation is determined, predicting movement behavior after the crash of the at least one target object based on the data describing the traffic environment by applying at least one crash situation model;
predicting further movement behavior of at least one further target object not involved in the crash situation based on the data describing the traffic environment by applying at least one traffic situation model;
generating prediction information based on the predicted movement behavior of the at least one target object and the further movement behavior of the at least one further target object;
generating an actuation signal based on the prediction information, andcontrolling an actuator for presenting information to a driver of the host vehicle or controlling the host vehicle based on the actuation signal.

Abstract
A method predicts trajectories of traffic objects to avoid collisions. The method estimates the probability for at least two traffic objects to collide, and predicts a potential movement of the traffic objects presumably involved in the collision after the collision. This information about a potential movement of the traffic objects can be used to plan a suitable trajectory path of an evasion maneuver for a host-vehicle employing the method. A system detects the collision situation and applies crash situation models to predict the future dynamic properties of other traffic objects that collide or are about to collide with each other. The method and system applies specific crash models like collision models, models derived from crash simulations and tests or models of human reactions in emergency situations.
