Vehicle Driving Assistance Control for Detection Failure Traffic Smoothing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle driving assistance systems disrupt smooth traffic when the following vehicle detection device malfunctions, as they cannot execute autonomous moving control to maintain optimal vehicle speed and inter-vehicle distance, leading to excessive changes in speed or distance that affect surrounding vehicles.
Innovation Solution
The system adjusts the set vehicle moving speed range or inter-vehicle distance range to be narrower when the following vehicle detection device is malfunctioning, allowing for autonomous control without disrupting traffic by maintaining these parameters within a tighter range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the autonomous moving control alternately increases and decreases vehicle speed or inter-vehicle distance to reduce energy consumption, then energy efficiency is improved, but traffic smoothness deteriorates when a following vehicle exists
Solution Approach 1:
The system uses detection devices to detect following vehicles and provides feedback to the autonomous moving control unit. When a following vehicle is detected, the control unit adjusts its speed variation behavior to prevent excessive speed changes that would disrupt traffic flow, while still maintaining energy-saving autonomous control when no following vehicle is present.
Solution Approach 2:
The autonomous moving control dynamically adjusts its control parameters based on the detection results. When a following vehicle is detected, the system reduces the degree of speed variation or inter-vehicle distance variation to maintain traffic smoothness. When no following vehicle is detected, the system can execute more aggressive energy-saving control with larger speed variations.
2Object-generated harmful factors
If the detection device is used to detect following vehicles for traffic smoothness maintenance, then traffic smoothness is improved, but system reliability deteriorates when the detection device malfunctions
Solution Approach 1:
The system prepares alternative control strategies in advance for different detection states. When the detection device is available, the system uses detection-based control to maintain traffic smoothness. When the detection device malfunctions, the system switches to a predetermined control mode that conservatively manages speed variations to prevent traffic disruption, ensuring reliable operation regardless of detection status.
3Device complexity
If the autonomous moving control executes without considering following vehicles to simplify control logic, then device complexity is reduced, but traffic smoothness deteriorates
Solution Approach 1:
The autonomous moving control unit is designed to perform multiple functions: it executes energy-saving speed variation control when no following vehicle is detected, and switches to traffic-smoothness-prioritizing control when a following vehicle is detected. This multi-functional design allows a single control system to handle both energy efficiency and traffic smoothness requirements without requiring separate control systems.

AI summary
A vehicle driving assistance apparatus, while executing a vehicle moving speed increasing/decreasing control, sets a set vehicle moving speed range such that the set vehicle moving speed range set when a control range change condition is satisfied, is narrower than the set vehicle moving speed range set when the control range change condition is unsatisfied, and while executing an inter-vehicle distance increasing/decreasing control, sets the set inter-vehicle distance range such that the set inter-vehicle distance range set when the control range change condition is satisfied, is narrower than the set inter-vehicle distance range set when the control range change condition is unsatisfied.
