Parking Assistance Unloading Mode for Passenger Disembarkation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems do not adequately support drivers with mobility issues or those needing extra space for unloading, as they often deactivate automatically during prolonged unloading processes, requiring manual intervention and keeping the engine running, which can lead to suboptimal parking paths and strategies.
Innovation Solution
A new 'unloading mode' is introduced that allows the vehicle to automatically stop at an optimal position for unloading, ignoring abort conditions and keeping the engine off until unloading is complete, enabling safe and efficient unloading of passengers or objects without interrupting the parking maneuver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the parking assistance system deactivates automatically during prolonged unloading processes, then the system returns to normal operation, but the driver is required to complete the maneuver manually and the engine remains running causing fuel consumption
Solution Approach 1:
The system dynamically switches between different operational modes (normal mode, unloading mode, pause mode) based on the driver's needs. The unloading mode is a dynamic state that can be activated during the parking maneuver to temporarily suspend automatic operation while maintaining system readiness, allowing the driver to unload without manual completion requirement.
Solution Approach 2:
The system changes its operational parameters when unloading mode is activated: the automatic parking maneuver is suspended, the engine stop-start function is deactivated, and the system waits for driver input. This parameter change allows prolonged unloading without automatic deactivation or manual completion requirements.
2Ease of operation
If the engine is kept running during the entire unloading process, then the vehicle is ready for immediate movement, but fuel is consumed unnecessarily
Solution Approach 1:
The engine control system dynamically adjusts its behavior based on the operational mode. During unloading mode, the engine remains running to ensure immediate vehicle readiness. When unloading mode is deactivated and normal parking mode resumes, the engine stop-start function becomes active again to reduce fuel consumption during the parked state.
3Adaptability or versatility
If the parking assistance system uses a fixed parking path and strategy, then the system is simple to implement, but it cannot adapt to different unloading requirements such as passengers with mobility issues or large objects
Solution Approach 1:
The parking maneuver is segmented into distinct phases: approach phase, unloading mode phase, and final parking phase. The unloading mode can be activated at any point during the maneuver, creating a separable intermediate state that allows flexibility without requiring complete redesign of the parking algorithm.
Solution Approach 2:
The unloading mode serves multiple functions: it allows passengers with mobility issues to disembark safely, enables removal of large objects from the trunk, and provides a temporary pause without aborting the maneuver. This single mode handles various unloading scenarios without requiring separate specialized systems.
4Productivity
If the system provides optimal parking path for standard maneuvers, then parking efficiency is maximized, but the path may not provide sufficient space for unloading operations
Solution Approach 1:
The parking path is dynamically adjusted when unloading mode is activated. Instead of following the pre-calculated optimal path to the final parked position, the system modifies the path to provide additional space for unloading operations. The vehicle stops at an intermediate position that offers better accessibility while maintaining the ability to complete the maneuver afterward.

AI summary
A parking assistance system for supporting a parking maneuver of a motor vehicle, during which the motor vehicle is automatically moved into a parked position. The parking assistance system has an unloading mode that can be activated by a user to enable the unloading of an object and/or to enable the disembarkation of a passenger before completion of the parking maneuver, wherein a temporary stop of the motor vehicle in an unloading position is automatically caused before reaching the parked position in response to the activation of said unloading mode.
