Solution Overview
Problem
Existing driving control systems for host vehicles lack effective methods to dynamically set and monitor safety envelopes based on real-time environmental conditions and positional relationships with target objects, leading to potential accidents and non-compliance with regulatory limits.
Innovation Solution
A processing system that acquires detection information, sets a safety envelope with physics-based boundaries, monitors for violations, and applies restriction or standard rules based on application conditions, ensuring compliance with regulatory limits and preventing accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed safety distance is used for driving control, then the control logic is simple, but it cannot adapt to dynamic environmental conditions and may cause accidents or regulatory non-compliance
Solution Approach 1:
The patent implements dynamic safety envelope setting by continuously adjusting the safety distance based on real-time detection information about the host vehicle's state, target object characteristics, and environmental conditions. The safety envelope transitions from a static fixed distance to a dynamic variable boundary that adapts to changing driving scenarios, resolving the contradiction between adaptability and complexity through systematic dynamic parameter adjustment.
Solution Approach 2:
The patent changes the parameter of safety distance from a constant value to a variable parameter that is continuously adjusted based on detection information. By modifying the safety distance parameter according to environmental conditions, target object types, and vehicle state, the system achieves adaptability while managing complexity through parameter-based control rather than complex structural changes.
2Reliability
If real-time monitoring of safety envelope violations is implemented, then accident prevention capability is improved, but computational load and processing time increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating safety envelope boundaries based on detection information before monitoring begins. The system establishes the safety envelope in advance using detected environmental conditions and target object positions, then simply monitors whether the host vehicle violates this pre-established boundary. This approach improves reliability through continuous monitoring while reducing processing time by avoiding real-time complex calculations during the monitoring phase.
3Reliability
If dynamic safety envelope setting based on detection information is used, then driving safety is improved, but system complexity and computational requirements increase
Solution Approach 1:
The patent achieves driving safety improvement through a universal safety envelope setting mechanism that handles multiple driving scenarios and target object types through a single integrated system. The processing system universally applies the same safety envelope logic across different environmental conditions, making the system reliable without proportionally increasing complexity through multiple specialized subsystems.

AI summary
A processing method for performing processing related to driving control of a host vehicle includes: acquiring detection information describing a state detected in a traveling environment of the host vehicle; determining a situation to be monitored for the host vehicle based on the detection information; setting a safety envelope based on the detection information to include defining a physics based boundary, margin, or buffer area around the host vehicle; monitoring a violation of the safety envelope based on a comparison between the safety envelope and a positional relationship between the host vehicle and a target moving object; and determining a rule for setting the safety envelope, which includes a restriction rule to be applied when an application condition is satisfied and a standard rule to be applied when the application condition is not satisfied, based on a determination result of whether the application condition is satisfied.
