Solution Overview

Problem

Existing vehicle accident response systems, such as eCall, often result in delayed rescue vehicle arrival due to inefficiencies in navigating to the accident location, particularly in situations where the vehicle's state may affect its ability to autonomously guide itself.

Innovation Solution

An apparatus and method that includes a communication device to transmit accident information to a server, a determination device to assess the vehicle's state for autonomous driving capability, and a driving controller to autonomously navigate the vehicle to the rescue vehicle's path, minimizing response time by selecting the most suitable location for meeting the rescue vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the eCall system transmits accident location information to a rescue center, then the rescue center can be notified of the accident, but the arrival time of the rescue vehicle is delayed

Engineering Contradiction:
Improveaccident location information transmissionVSAvoidrescue vehicle arrival time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by having the vehicle autonomously move toward the rescue vehicle's predicted location before the rescue vehicle arrives. The driving controller continuously monitors rescue vehicle position and adjusts the vehicle's path in advance, rather than waiting passively for rescue arrival.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The server acts as an intermediary by receiving real-time location data from both the accident vehicle and rescue vehicle, calculating optimal meeting points, and transmitting this path information back to the vehicle's driving controller to coordinate their movements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If the vehicle autonomously drives to meet the rescue vehicle, then the response time is reduced, but the system complexity increases

Engineering Contradiction:
Improveemergency response timeVSAvoidautonomous driving control system
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The driving controller leverages existing autonomous driving components (sensors, processors, actuators) for a new emergency function. The same hardware used for normal autonomous navigation is repurposed to execute emergency meeting maneuvers, avoiding additional dedicated components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The vehicle's own autonomous driving system serves the emergency response function. The driving controller uses the vehicle's existing capability to autonomously navigate and position itself, making the vehicle self-sufficient in the emergency situation without requiring external physical assistance.

Inventive Principle:
Principle #25Self-service

3Loss of time

If the vehicle autonomously navigates to the rescue vehicle's path, then the meeting time is minimized, but the reliability of autonomous driving capability must be ensured

Engineering Contradiction:
Improvetime to meet rescue vehicleVSAvoidautonomous driving capability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The determination device performs preliminary assessment of autonomous driving capability before initiating the emergency meeting maneuver. It checks sensor functionality, communication status, and basic vehicle control systems in advance to ensure reliability before relying on autonomous navigation for emergency response.

Inventive Principle:
Principle #10Preliminary action

AI summary

An apparatus for controlling driving of a vehicle includes a communication device transmitting information indicating that an event of the vehicle occurs to a server and receiving path information of a rescue vehicle associated with a location where the event occurs from the server, a determination device determining whether autonomous driving is possible based on state information of the vehicle if the event occurs, and a driving controller controlling the autonomous driving of the vehicle based on the path information of the rescue vehicle if the autonomous driving is possible.
