Driving Maneuver Selection for Expanding Sensor Detection Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dynamic traffic situations are often hindered by restricted visibility due to obscuring objects, which complicates the detection area of environment sensor systems, making it challenging for automated driving functions, especially when the detection area changes due to vehicle movement or dynamic objects.
Innovation Solution
A method using a control unit to receive and evaluate measurement data from sensors, create a sensor model, and simulate potential driving maneuvers to determine the change in the detection area, allowing for optimization of the detection area by selecting maneuvers that increase visibility, such as stopping or slow approaches, to improve the sensor's range and reduce obscuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If automated driving functions are implemented in normal control units, then device complexity is reduced, but processing capability is insufficient due to intensive computational requirements
Solution Approach 1:
The patent pre-calculates and stores detection area information for multiple possible driving maneuvers before actual decision-making. This preliminary preparation of detection area data allows the control unit to perform rapid comparisons and selections during real-time operation, reducing computational burden while maintaining high processing capability for maneuver selection
2Loss of information
If the detection area is optimized by selecting specific driving maneuvers, then visibility is improved, but loss of time occurs due to additional processing requirements
Solution Approach 1:
The system pre-calculates detection areas for multiple candidate maneuvers in advance, storing this information for rapid retrieval. During actual operation, the control unit only needs to compare pre-computed detection area data and select the optimal maneuver, significantly reducing real-time processing time while maintaining optimized visibility
Solution Approach 2:
The patent dynamically adapts the detection area optimization process to current traffic conditions. By evaluating multiple candidate maneuvers and selecting based on real-time visibility requirements, the system achieves adaptive optimization that balances visibility improvement with processing time constraints

AI summary
A method for determining a driving maneuver of a vehicle with a control unit includes receiving a measurement data relating to a traffic situation from a sensor, determining a current detection area of the sensor by evaluating the measurement data, and creating a sensor model based on the measurement data. An estimated detection area of the sensor from the measurement data is modelled through forward simulation based on a vehicle position of the vehicle. A change in the estimated detection area of the sensor due to a driving maneuver is determined along with the driving maneuver that causes an increase in the estimated detection area due to the sensor model.
