Integrated Controller for Driver Assistance System Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The simultaneous operation of multiple driver assistance systems in vehicles can lead to confusion and dangerous situations, as they may interfere with each other's operations, such as during automatic parking, where systems like Smart Parking Assistance, Smart Cruise Control, and Idle Stop and Go may conflict, disrupting the control processes.
Innovation Solution
An integrated control apparatus and method that includes a first driver assistance system control module, a second control module for other systems, and an integrated control module to manage and coordinate the operation of these systems by transmitting activation and deactivation signals based on operating state signals, ensuring that only the necessary systems are active during specific vehicle operations to prevent conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driver assistance systems operate simultaneously, then the functionality and assistance coverage are improved, but system conflicts and operational reliability deteriorate
Solution Approach 1:
An integrated control module is introduced as an intermediary between multiple driver assistance systems. This module receives operating state signals from various systems (SCC, TJA, AEB, CTA, ABSD, SPAS), determines system conflicts based on predetermined criteria, and transmits activation control signals to resolve conflicts. The intermediary coordinates system operations to prevent conflicts while maintaining comprehensive functionality.
Solution Approach 2:
The system dynamically adjusts the operational state of driver assistance systems based on real-time conditions. The integrated control module continuously monitors operating state signals and activates or deactivates specific systems according to current vehicle conditions and conflict detection results, making the system adaptable and reliable under varying circumstances.
2Use of energy by moving object
If the Idle Stop and Go system operates simultaneously with other driver assistance systems, then fuel economy is improved, but system operation stability deteriorates
Solution Approach 1:
The integrated control module applies preliminary anti-action by detecting potential conflicts between the Idle Stop and Go system and other driver assistance systems before they occur. When a conflict is anticipated (e.g., during automatic parking operations), the module preemptively transmits activation control signals to prevent the Idle Stop and Go system from disrupting other systems, thereby maintaining operational stability while still allowing fuel economy improvements during non-conflicting periods.
3Reliability
If brake control of driver assistance systems is activated during automatic parking, then safety response is improved, but parking control precision deteriorates
Solution Approach 1:
The integrated control module serves as an intermediary that receives brake control requests from driver assistance systems during automatic parking operations. It evaluates these requests against predetermined conflict criteria and selectively transmits activation control signals to the brake system only when safe and appropriate, preventing unnecessary brake activations that would disrupt parking precision while maintaining safety response capability when genuinely needed.

AI summary
An apparatus and method for integrated control of driver assistance systems (DAS). The apparatus includes a first processor configured to control at least one first driver assistance system; a second processor configured to control at least one second driver assistance system; and an integrated controller configured to transmit a deactivation signal to the second processor to deactivate the at least one second driver assistance system when an activation signal is transmitted to the first processor.
