Solution Overview

Problem

Existing vehicle collision prevention technologies fail to effectively manage secondary collisions caused by external forces, leading to increased accidents and injuries due to uncontrolled vehicle movements and lack of immediate driver intervention.

Innovation Solution

A vehicle equipped with a chassis, steering unit, brake unit, and detector system that automatically controls steering, braking, and damping based on detected movement information, including yaw rate and lateral acceleration, to stabilize the vehicle and prevent secondary collisions, while also enabling user override and emergency lighting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If automatic control of steering and braking is implemented to prevent secondary collisions, then vehicle stability is improved, but device complexity increases

Engineering Contradiction:
Improvevehicle stabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The vehicle control system automatically detects collision conditions and executes steering and braking operations without requiring driver intervention. The controller monitors movement information from detectors and autonomously controls the steering unit and brake unit to stabilize the vehicle, making the system self-serving in preventing secondary collisions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors movement information through detectors and uses this feedback to adjust steering and braking operations. The controller receives real-time data about vehicle movement and external forces, then modifies control actions accordingly to maintain stability during and after collision events.

Inventive Principle:
Principle #23Feedback

2Reliability

If electromagnetic force is generated without confirming electromagnet mounting, then collision prevention is improved, but harmful effects increase due to magnetic force on vehicles without electromagnets

Engineering Contradiction:
Improvecollision prevention reliabilityVSAvoidmagnetic force harm
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection to confirm the presence of an electromagnet on the other vehicle before generating electromagnetic force. The detector checks for electromagnet mounting status in advance, and only if confirmed does the controller activate the electromagnetic repulsion force, preventing harmful effects on vehicles without electromagnets.

Inventive Principle:
Principle #10Preliminary action

3Speed

If repulsive magnetic force is increased as distance decreases, then collision avoidance is improved, but driver impact increases causing secondary collisions

Engineering Contradiction:
Improvecollision avoidance speedVSAvoiddriver impact
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The system applies preliminary braking force before the vehicle comes to a complete stop to reduce the impact on the driver. By controlling the braking unit to apply gradual deceleration, the system prevents sudden stops that would cause driver injury and potential secondary collisions, while still maintaining effective collision avoidance capability.

Inventive Principle:
Principle #9Preliminary anti-action

4Reliability

If automatic control operates without user override capability, then collision prevention is improved, but ease of operation deteriorates when user intervention is needed

Engineering Contradiction:
Improvecollision prevention reliabilityVSAvoiduser intervention capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The control system dynamically switches between automatic control mode and manual override mode based on user input. During automatic operation, the controller manages steering and braking autonomously, but when the user operates the steering wheel or brake pedal, the system transitions to manual mode, allowing flexible adaptation to different operational needs while maintaining both reliability and ease of operation.

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed herein are a vehicle configured to prevent a collision and a control method thereof. The vehicle includes a chassis; a steering unit configured to change a direction of the chassis; a brake unit configured to adjust a braking force of the chassis; a detector configured to detect movement information of the chassis; and a controller configured to confirm a variation rate of movement of the chassis based on the detected movement information and configured to automatically control an operation of the steering unit and the brake unit when the confirmed variation rate is out of a reference range. When a collision occurs, the vehicle may automatically perform at least one of steering control, side braking control, or a damping control, and thus a secondary collision may be prevented, the incidence of additional injury may be reduced, the speed of the vehicle may be stably reduced or stopped, and the vehicle may be moved to a safe lane so that a stabilization time of the vehicle may be reduced.
