Control system and method for determining a lane of a following vehicle
First Claim
1. A vehicle control system for detecting following vehicles on the basis of environmental data, the vehicle control system comprising:
- an electronic controller; and
one or several environmental sensors disposed on the vehicle, the environmental sensors being adapted to provide the electronic controller with the environmental data which reflect the area in front of, laterally next to and/or behind the vehicle,wherein the electronic controller is adapted to;
detect a course (210) of the own lane (L) of the own vehicle (ego) with reference to environmental data provided by the environmental sensors, the environmental data representing one or several demarcation lines of the own lane applied to a surface of a road for an area lying in front of, laterally in front of, and/or laterally next to the vehicle,store data reflecting a position of the one or several demarcation lines over a predefined road section as a trajectory (220) of the lane progression,transfer the course of the own lane to all other lanes of the road,detect one or several other vehicles (alter) participating in traffic behind the own vehicle (ego) by means of the environmental sensors,detect a lane (L, R) associated with each other vehicle in which the other vehicle(s) (alter) drive(s), taking the stored trajectory (220) of the lane progression of the own lane (L) and the transferred course of the other lanes into account,determine an occupancy of the own lane (L) and/or of at least one adjacent lane (R) by the other vehicle(s) (alter), taking the stored course (210) of the own lane (L) into account, andon the basis of the determined occupancy;
(i) to output a corresponding indication about the occupancy of the own lane (L) and/or of the at least one adjacent lane (R), (ii) to output an indication on a safe or unsafe lane change to a specific of the at least one adjacent lane (R) and/or (iii) to perform an autonomous lane change to the specific of the at least one adjacent lane (R) by the own vehicle (ego) if the determined occupancy allows a safe change of lane.

Abstract
A Control system, which is adapted for application in a vehicle and intended to detect following vehicles on the basis of environmental data which are obtained from one or several environmental sensors disposed on the vehicle and which reflect the area in front of, laterally next to, and/or behind the vehicle. The control system is adapted to detect a course of the own lane of the vehicle and to store it over a predefined road section, and to detect one or several other vehicles participating in traffic behind the own vehicle with the environmental sensors. A lane associated with each other vehicle, in which the other vehicle(s) drive(s), is detected, taking the stored course of the own lane into account. An occupancy of the own lane and/or of at least one adjacent lane by the other vehicle(s) is determined.

3. A control method, which in a vehicle is for detecting following vehicles based on environmental data obtained from one or several environmental sensor(s) disposed on the vehicle, with the steps of:
-
providing an electronic controller in the own vehicle (ego) by means of the environmental sensors with environmental data reflecting the area in front of, laterally in front of and/or laterally next to and/or behind the vehicle, detecting a course (210) of the own lane (L) of the own vehicle (ego) with reference to environmental data provided by the environmental sensors, the environmental data representing one or several demarcation lines of the own lane applied to a surface of a road for the area lying in front of, laterally in front of, and/or laterally next to the vehicle, storing data reflecting a position of the one or several demarcation lines over a predefined road section as a trajectory (220) of the lane progression, transferring the course of the own lane to all other lanes of the road, detecting one or several other vehicles (alter) participating in traffic behind the own vehicle (ego) with the environmental sensors, detecting a lane (L, R) associated with each other vehicle (alter), in which the other vehicle(s) (alter) drive(s), taking the stored trajectory (220) of the lane progression of the own lane (L) and the transferred course of the other lanes into account, determining an occupancy of the own lane (L) and/or of at least one adjacent lane (R) by the other vehicle(s) (alter), taking the stored trajectory (220) of the lane progression of the own lane (L) and the transferred course of the other lanes into account, and on the basis of the determined occupancy (i) outputting a corresponding indication about the occupancy of the own lane (L) and/or of the at least one adjacent lane (R), (ii) outputting an indication on a safe or unsafe lane change to a specific of the at least one adjacent lane (R) and/or (iii) performing an autonomous lane change to the specific of the at least one adjacent lane (R) by the own vehicle (ego) if the determined occupancy permits a safe change of lane. - View Dependent Claims (4)
