Autonomous Vehicle Control Apparatus Destination Input During General Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous vehicle control systems do not provide a safe method for drivers to set a destination while the vehicle is in motion, as it requires the driver's attention, increasing the risk of adverse events.
Innovation Solution
An autonomous vehicle control apparatus and method that allows drivers to activate the lane keeping assist system (LKAS) and smart cruise control (SCC) during general driving, enabling the controller to receive and process the destination input without the driver's direct attention, using an input device and controller to manage lane keeping, speed, and inter-vehicle distance before entering autonomous driving mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver inputs the destination while the autonomous vehicle is being driven, then the path can be set for autonomous driving, but the driver's attention is distracted causing safety risks
Solution Approach 1:
The system activates the lane keeping assist system and smart cruise control system before the driver inputs the destination. This preliminary activation of assistance systems prepares the vehicle for autonomous driving mode transition, allowing the driver to input destination information safely without full attention on the road, as the vehicle begins to operate with automated lane keeping and speed control
Solution Approach 2:
The lane keeping assist system and smart cruise control system act as intermediaries between the driver and the autonomous driving mode. These systems provide partial automation during the transition period, bridging the gap between manual driving and full autonomous mode, enabling safe destination input while maintaining adequate vehicle control
2Reliability
If the autonomous vehicle waits to be stopped before receiving destination input, then driver safety is maintained, but the switching time to autonomous driving increases
Solution Approach 1:
The system performs preliminary actions by activating the lane keeping assist system and smart cruise control system before the driver inputs the destination. This allows the vehicle to begin automated operations in advance, reducing the overall time to transition to autonomous mode while maintaining safety through progressive activation of assistance systems rather than requiring complete stopping
3Reliability
If conventional systems only output warnings when driver input is required during driving, then safety is emphasized, but no alternative solution is provided
Solution Approach 1:
Instead of merely warning the driver, the system introduces intermediary assistance systems (lane keeping assist and smart cruise control) that actively participate in the transition to autonomous mode. These intermediaries provide a practical alternative solution that maintains safety while enabling flexible destination input during driving, moving beyond simple warnings to active assistance

AI summary
An autonomous vehicle control apparatus includes an input device for receiving an activation signal of an autonomous driving mode from a driver, and a controller for controlling a lane keeping, a vehicle speed keeping, and an inter-vehicle distance keeping before entering the autonomous driving mode in response to the activation signal of the autonomous driving mode input through the input device during general driving.
