Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated braking is executed based on simple obstacle detection, then safety is improved, but excessive braking occurs that hinders driver's intended travel
Solution Approach 1:
The patent divides the detection space into multiple zones (first detection zone, second detection zone, third detection zone) with different braking control characteristics. Each zone has specific angular ranges and distance thresholds that determine different braking behaviors, allowing the system to provide appropriate braking response based on the local spatial characteristics of detected objects.
Solution Approach 2:
The automated braking control device dynamically adjusts braking force based on real-time detection results, vehicle speed, and object position. The braking control is not fixed but adapts to changing conditions, modulating brake application according to the specific situation to avoid excessive braking while maintaining safety.
2Measurement precision
If automated braking execution area is set wide to improve safety, then detection accuracy is improved, but excessive braking control is triggered
Solution Approach 1:
Different detection zones have different angular widths and distance thresholds. The first detection zone has a specific angular range for forward detection, the second detection zone has a different angular range for backward detection, and the third detection zone has yet another configuration. This localized differentiation allows accurate detection without triggering excessive braking.
Solution Approach 2:
The system changes detection parameters (angular ranges, distance thresholds) based on the specific detection zone and vehicle conditions. By adjusting these parameters locally for different zones and situations, the system achieves accurate detection while avoiding unnecessary braking activations.
3Reliability
If automated braking is executed for all detected obstacles, then safety is improved, but driver's travel desire is hindered
Solution Approach 1:
The patent implements zone-specific braking control where different detection zones trigger different braking responses. Some zones may trigger strong braking, others moderate braking, and some may not trigger braking at all depending on the object type and position. This localized differentiation maintains safety for critical obstacles while allowing normal travel for non-critical situations.
Solution Approach 2:
The system applies partial braking action rather than full braking for all detected objects. The braking control is modulated to provide only the necessary braking force for each specific situation, avoiding excessive braking that would hinder normal travel while still providing adequate safety response for actual hazards.
