Vehicle Warning Suppression During Remote Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles equipped with keyless ignition systems face user dissatisfaction due to unnecessary warning messages, such as horn chirps, when the driver leaves the engine running in an enclosed space while using remote parking features, as these warnings can be intrusive and confusing during active remote parking operations.
Innovation Solution
The system determines the vehicle's location and surroundings using sensors and ADAS controllers to suppress or delay warning messages, such as horn chirps, if the vehicle is not in an enclosed space, allowing remote parking operations to proceed without interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system provides warning messages when the key is outside the vehicle and the engine is running, then safety is improved by preventing accidental engine shutdown in enclosed spaces, but user satisfaction deteriorates due to unnecessary warnings during remote parking operations
Solution Approach 1:
The warning system dynamically adjusts its behavior based on the detected parking scenario. When remote parking is detected, the system suppresses warnings even though the key is outside and engine is running. When remote parking is not active, the system provides warnings as usual. This dynamic adaptation resolves the contradiction by making the warning system context-aware rather than static.
Solution Approach 2:
The system uses feedback from multiple sensors (key position, engine status, enclosure detection, remote parking status) to determine whether to issue warnings. The feedback loop continuously monitors these parameters and adjusts warning behavior accordingly, allowing the system to distinguish between dangerous situations requiring warnings and normal remote parking operations where warnings should be suppressed.
2Reliability
If the system provides continuous warning messages to remind users about running engines, then reliability is improved by preventing accidental shutdowns, but productivity deteriorates due to interruptions during remote parking procedures
Solution Approach 1:
The warning system transitions from a static continuous warning mode to a dynamic conditional mode. By detecting remote parking operations, the system dynamically suppresses warnings during these procedures, eliminating interruptions and improving remote parking efficiency while maintaining reliability through selective warning suppression rather than complete disablement.
Solution Approach 2:
The system applies different warning behaviors to different operational contexts. Instead of a uniform warning approach, it applies warning suppression locally during remote parking operations while maintaining normal warning behavior for other situations. This localized differentiation resolves the contradiction by tailoring the warning behavior to the specific operational context.
3Device complexity
If the system uses simple key-position-based warning logic, then device complexity is reduced, but measurement precision deteriorates by failing to distinguish between dangerous and normal situations
Solution Approach 1:
The control module performs multiple functions: it monitors key position, engine status, enclosure conditions, and remote parking status, then integrates this information to make warning decisions. This multi-functional approach increases measurement precision by considering multiple parameters rather than just key position, while the integration is handled by a single control module that already exists in the vehicle system.
Solution Approach 2:
The control module acts as an intermediary that processes information from multiple sources (key position sensors, engine status, enclosure detectors, remote parking system) and produces the final warning decision. This intermediary layer enables precise situation detection by synthesizing multiple data streams without requiring complex distributed decision-making across multiple independent systems.

AI summary
Systems and methods for driver presence and position detection are disclosed herein. A method can include determining whether a vehicle is in an open area or an enclosed area, determining that a key of the vehicle is no longer present inside the vehicle and an ignition of the vehicle is on, suppressing or delaying a warning message that indicates that the key of the vehicle is no longer present inside the vehicle and the vehicle is in the open area, and providing the warning message when the vehicle is in the enclosed area.
