Solution Overview

Problem

Existing autonomous driving systems require users to manually reconfigure the automatic speed setting mode when transitioning between roads with and without speed limit support, causing inconvenience and potential unintended mode deactivation.

Innovation Solution

An apparatus and method that utilize a path guide device and controller to automatically activate and deactivate the speed setting mode based on road type and user input, ensuring seamless transitions and reflecting user intentions by storing and reactivating the mode as necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the automatic setting mode is automatically released when the vehicle enters a road without speed limit support, then the system adapts to road conditions, but the user must manually reconfigure the mode when returning to supported roads, reducing convenience

Engineering Contradiction:
Improveadaptation to road conditionsVSAvoidmanual reconfiguration requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The controller stores the activation state of the automatic setting mode before the vehicle enters a road without speed limit support. When the vehicle returns to a supported road, the controller automatically restores the mode based on the stored state, eliminating the need for manual reconfiguration and improving ease of operation while maintaining adaptability

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the automatic setting mode is automatically reactivated when the vehicle returns to a supported road, then user convenience is improved, but the system may reactivate the mode against user intention, reducing reliability

Engineering Contradiction:
Improveautomatic mode restorationVSAvoiduser intention accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The controller provides feedback to the user through a notification (display or audio signal) before automatically reactivating the automatic setting mode. This allows the user to confirm or cancel the reactivation, ensuring the system acts according to user intention while maintaining the convenience of automatic restoration

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the system continuously monitors road type and mode state for automatic activation/deactivation, then seamless transitions are achieved, but the device complexity increases

Engineering Contradiction:
Improveseamless mode transitionsVSAvoidcontrol logic complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The controller stores the activation state in advance before road transitions occur. This preliminary action simplifies the control logic by avoiding the need for continuous complex monitoring and decision-making during transitions, achieving seamless mode restoration while reducing device complexity

Inventive Principle:
Principle #10Preliminary action

AI summary

An apparatus for automatically setting a speed of a vehicle may include a path guide device configured to obtain information related to a location of the vehicle, a type of a road corresponding to the location, and a speed limit of the road corresponding to the location and a controller configured to be electronically connected to the path guide device, wherein the controller is configured to activate an automatic setting mode for setting a setting speed for autonomous driving of the vehicle to a speed limit of a road corresponding to a current location of the vehicle, when the vehicle enters another type of road from the specified type of road in a state where the automatic setting mode is activated, release the automatic setting mode, and activate the automatic setting mode.
