Lane Change Collision Avoidance via Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is an increased risk of accidents when vehicles change lanes on multi-lane carriageways, particularly when multiple vehicles attempt to change to the same lane simultaneously, leading to potential near collisions or actual collisions.
Innovation Solution
A method for operating a motor vehicle that detects impending lane changes of both the vehicle and adjacent vehicles using a monitoring system, outputs a warning signal, and adjusts the vehicle's lateral guidance to prevent collisions by monitoring an expanded area to anticipate simultaneous lane change intentions and intervene early to avoid collisions.

Engineering Contradiction Analysis
1Reliability
If the monitoring area is expanded to detect lane change intentions of vehicles in adjacent lanes, then the detection capability and safety are improved, but the device complexity and computational load increase
Solution Approach 1:
The system detects lane change intentions before actual lane changes occur by monitoring turn signals and steering movements. This preliminary detection allows the system to predict potential collision scenarios and prepare appropriate responses in advance, improving safety without requiring complex real-time collision prediction algorithms for all possible scenarios
Solution Approach 2:
The monitoring system acts as an intermediary between the driver's lane change intention and the actual lane change execution. It detects intentions through turn signals and steering movements, evaluates collision risks, and provides warning signals or automatic interventions, thereby mediating between driver input and vehicle response to prevent collisions
2Reliability
If automatic intervention in lateral guidance is implemented to prevent collisions, then safety is improved, but the ease of operation and driver control are reduced
Solution Approach 1:
The system provides feedback to the driver through warning signals when potential collision scenarios are detected. This feedback loop allows the driver to maintain control by overriding the system's warnings if the driver determines the lane change is safe, while still benefiting from the system's collision detection capabilities. The feedback mechanism balances safety intervention with driver autonomy
Solution Approach 2:
The level of automatic intervention is dynamic rather than fixed. The system can operate in different modes: providing only warnings to maintain full driver control, or implementing automatic lateral guidance corrections when collision risk is high. This dynamic approach allows the system to adapt to different driving situations and driver preferences, balancing safety intervention with driver control freedom

AI summary
The invention relates to a method for operating a motor vehicle when changing lanes on a one-way roadway (22) comprising at least three lanes (20, 24, 26), said method comprising the steps: detecting, by means of a monitoring system (12) of the motor vehicle (10), an impending lane change of the motor vehicle (10) from a first lane (20) to an adjacent second lane (26); detecting an impending lane change of another vehicle (18) to the second lane (26) from a third lane (24) adjacent to the second lane (26); determining, by means of the monitoring system (12), whether a performance of the lane change by the motor vehicle (10) runs the risk of a collision with the other vehicle (18); and outputting a warning signal by means of a warning device (14) and/or influencing the transverse guidance of the motor vehicle (10) by means of a driver assistance system (16) of the motor vehicle (10) as soon as the risk of a collision is detected. The invention also relates to a motor vehicle (10) having a monitoring system (12).
