Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advanced driver assistance systems (ADAS) lack the ability to optimize autonomous driving visibility information and perform seamless cruise control without deceleration, especially when encountering slower-moving vehicles, leading to inefficiencies in lane changes and potential collisions.
Innovation Solution
A route providing device that receives map information and sensing data from sensors to specify the vehicle's lane and estimate an optimal route, generating autonomous driving visibility information by fusing this data with dynamic information, allowing for optimized cruise control and lane changes while maintaining set speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle decelerates to avoid collision with slower-moving vehicles, then safety is improved, but driving efficiency and productivity deteriorate
Solution Approach 1:
The system segments the driving task into multiple components: lane detection, lane change feasibility assessment, and speed maintenance control. By dividing the problem, the system can execute lane changes to avoid slower vehicles without unnecessary deceleration, maintaining productivity while ensuring safety through structured decision-making.
Solution Approach 2:
The system performs preliminary lane change assessments by evaluating map information, sensing data, and predicted vehicle positions before executing maneuvers. This advance planning allows the vehicle to proactively change lanes to avoid slower-moving vehicles, preventing the need for reactive deceleration and maintaining driving efficiency.
2Productivity
If the vehicle performs frequent lane changes to maintain set speed, then driving efficiency is improved, but safety and stability deteriorate
Solution Approach 1:
The system continuously monitors vehicle position, lane markings, and surrounding environment through sensors and map data. This real-time feedback enables the vehicle to assess lane change safety dynamically, executing maneuvers only when conditions are favorable, thus maintaining driving efficiency without compromising safety through excessive or unsafe lane changes.
Solution Approach 2:
The lane change decision system is dynamic and adaptive, adjusting its behavior based on real-time conditions. Rather than performing frequent fixed-pattern lane changes, the system dynamically evaluates each situation using sensing information and map data, executing lane changes only when safety conditions are met, thereby balancing efficiency and stability.
3Device complexity
If the vehicle uses basic sensing information without fusion, then system complexity is reduced, but measurement precision and reliability of autonomous driving visibility information deteriorate
Solution Approach 1:
The system merges multiple information sources including map data, sensing information from various sensors, and predicted vehicle positions into a unified autonomous driving visibility information structure. This fusion of diverse data sources enhances measurement precision and reliability of the visibility information without requiring overly complex individual sensor systems.
Solution Approach 2:
The fused autonomous driving visibility information serves multiple functions: lane detection, lane change assessment, and collision avoidance. By creating a universal information structure that performs multiple functions, the system achieves high measurement precision across different tasks without proportionally increasing device complexity.
