Driver Assistance Steering Angle Blocking for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems face high computing effort when dealing with multiple objects in the vehicle's surroundings, leading to inefficient collision avoidance and loss of overall overview, as each object must be considered individually, and limiting the area of consideration can result in missed objects and increased complexity.
Innovation Solution
The system determines blocked steering angle ranges based on the position and spatial dimensions of detected objects, allowing the driver assistance system to operate by identifying steering angles that would result in collisions, and merging overlapping ranges to reduce computational load and improve collision avoidance.

Engineering Contradiction Analysis
1Reliability
If each object is considered individually in driver assistance systems for collision avoidance, then the system can detect and respond to each object separately, but the computing effort becomes very large with a large number of objects
Solution Approach 1:
The patent merges multiple individual object considerations into a unified blocked steering angle range representation. Instead of processing each object separately, the system combines all objects into a single blocked steering angle range that represents all collision-prone steering angles collectively, significantly reducing computing effort while maintaining collision avoidance reliability
Solution Approach 2:
The patent segments the steering angle space into blocked and non-blocked ranges based on object positions. By dividing the continuous steering angle domain into discrete safe and unsafe zones, the system simplifies the collision avoidance problem from continuous optimization to discrete range identification, reducing computational complexity
2Device complexity
If the area under consideration is limited in the vicinity of the motor vehicle to minimize computing effort, then the computing load is reduced, but not all objects in the area are taken into account and the overall overview is lost
Solution Approach 1:
The patent transforms the spatial problem from three-dimensional space consideration to one-dimensional steering angle representation. By projecting all spatial objects onto the steering angle dimension, the system maintains comprehensive object awareness while reducing the problem to a single dimension, eliminating the need to arbitrarily limit the consideration area
3Reliability
If the combination of several objects is performed to find a collision-free path, then a more comprehensive collision avoidance strategy is achieved, but additional calculation steps are required
Solution Approach 1:
The patent merges multiple objects into a single blocked steering angle range representation, eliminating the need for separate combination calculations for each object pair. This unified approach achieves comprehensive collision avoidance while minimizing calculation steps by processing all objects simultaneously through a single range determination
