Lane Change Warning Control for Adjacent Vehicles and Crosswind Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane change decision aid systems (LCDAS) do not provide comprehensive detection and warning for potential collisions and lateral wind disturbances, and lack automatic control actions to prevent accidents.
Innovation Solution
A system that integrates sensors to detect vehicles in adjacent and rear zones, provides visual, audible, and haptic warnings based on vehicle type and proximity, and optionally controls vehicle steering and speed to mitigate potential collisions and lateral wind effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors and control systems are integrated to provide comprehensive detection and automatic control actions, then safety and collision prevention are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensing systems (cameras, radar, LIDAR), warning systems (visual, audible, haptic), and control systems (steering control, brake control, acceleration control) into an integrated LCDAS that functions as a unified safety system, resolving the contradiction by merging components to achieve comprehensive collision prevention while managing complexity through systematic integration
Solution Approach 2:
The LCDAS is designed as a multi-functional system that performs detection, warning, and automatic control functions across multiple domains (lateral collision, rear collision, lateral wind), allowing a single system to address various safety scenarios simultaneously, thereby improving reliability without proportionally increasing complexity
2Reliability
If automatic control actions (steering control, brake control) are activated to prevent accidents, then safety is improved, but ease of operation deteriorates as the system takes control from the driver
Solution Approach 1:
The system applies preliminary anti-action by implementing warning functions (visual, audible, haptic) before activating automatic control actions. This staged approach allows the driver to maintain control while being warned of potential hazards, and only intervenes automatically when necessary, thus preventing accidents while preserving driver ease of operation during normal conditions
Solution Approach 2:
The LCDAS dynamically adjusts its level of intervention based on the severity and immediacy of detected hazards. The system transitions from passive detection to active warning to automatic control only when required, creating a dynamic balance between safety intervention and driver operational control rather than a fixed state of either full manual or full automatic control

AI summary
The present disclosure relates to a vehicle and a control method thereof, and more particularly, to an apparatus and a method for implementing a lane change decision aid system (LCDAS). The LCDAS apparatus includes: a sensing device for sensing whether a target vehicle is in adjacent zones of a subject vehicle, whether the target vehicle is in a rear zone of the subject vehicle, or whether the target vehicle is a large vehicle or a compact vehicle; a processor for determining an activation condition for determining whether an LCDAS function is active / inactive and a warning condition for determining whether a warning of the LCDAS function is issued / un-issued, based on a sensing result of the sensing device; a warning device for issuing the warning to a driver based on a determination result of the processor; and a controller for controlling the sensing device, the processor, and the warning device.
