Driver Assistance Apparatus for Seamless Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote smart parking assist systems require drivers to restart the engine when transitioning from a normal starting mode to a remote starting mode, causing inconvenience, especially when entering or exiting a vehicle in narrow spaces.
Innovation Solution
A driver assistance apparatus that includes a user interface, surroundings sensor, getting-on/off sensor, and controller to discern the driver's intention, allowing seamless switching between normal and remote starting modes without the need for engine restart, by sensing user input, vehicle position, and remote control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the engine is stopped when the driver gets out of the vehicle in conventional RSPA system, then the vehicle can be remotely controlled to enter/exit or park, but the driver has to restart the engine causing inconvenience
Solution Approach 1:
The system performs preliminary actions by maintaining the engine running state before remote control operations are needed. When the driver exits the vehicle, the controller automatically maintains or restarts the engine without requiring driver intervention, so that the engine is already running when remote control functions are activated, eliminating the need for manual restart during operation
2Ease of operation
If the engine is kept running when the driver exits the vehicle, then remote control operations can be performed without restarting, but the engine continues to consume fuel and generate noise
Solution Approach 1:
The system dynamically adjusts the engine operating state based on real-time detection of driver intent. The controller monitors signals from the user interface and surrounding sensors to determine whether the driver intends to perform remote control operations. The engine state (running or stopped) is dynamically changed according to the detected intent, optimizing the balance between operational convenience and fuel consumption
3Ease of operation
If the system automatically detects driver intent, then the starting mode can be switched seamlessly, but the system complexity increases with additional sensors and control logic
Solution Approach 1:
The controller leverages existing multi-functional components already present in the vehicle system. The user interface, surrounding sensors, and getting-on/off sensors are not dedicated solely to intent detection but serve multiple functions including safety monitoring, parking assistance, and vehicle state management. This multi-functional approach allows intent detection capability to be added without proportionally increasing overall system complexity

AI summary
A driver assistance apparatus includes: a user interface generating a user input; a surroundings sensor obtaining surrounding information; and a controller verifying whether a user's intention is a remote control intention or a remote control termination intention based on at least one of the user input or the surrounding information and switching a starting mode in a case that the user's intention is the remote control intention or the remote control termination intention.
