Adaptive Lane-Change Following Control for Smooth Vehicle Acceleration

Solution Overview

Problem

In vehicle following control situations, sudden acceleration and deceleration can occur when a lane change is performed, potentially leading to driver discomfort and increased risk of collision.

Innovation Solution

A vehicle control device and method that determines the possibility of a lane change and calculates the required acceleration for changing a following target based on vehicle behavior information, lane information, and surrounding vehicle detection information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lane change is performed in vehicle following control situation, then the vehicle can change lanes to improve driving flexibility, but sudden acceleration and deceleration occur causing driver discomfort and potential collision

Engineering Contradiction:

Improvedriving flexibilityVSAvoidcollision risk

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary detection of surrounding vehicles and calculates required acceleration before the lane change is executed. By anticipating the lane change maneuver and preparing the appropriate acceleration profile in advance, the system ensures smooth transitions that prevent sudden movements and potential collisions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the required acceleration based on real-time lane change state, vehicle behavior information, and surrounding vehicle detection. The acceleration profile changes continuously during the lane change process rather than remaining fixed, enabling smooth transitions that adapt to the actual driving conditions.
