Vehicle Key Positioning for Predictive Function Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack automated activation of functions when stationary, requiring user interaction and inefficient preparation for starting, leading to potential wear on components.
Innovation Solution
A system that determines the position of a vehicle and associated key elements using satellite-aided positioning and data exchange, automatically activating vehicle functions based on relative movement and probability calculations, allowing for remote activation and optimized preparation without user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicle functions are activated only when key element is detected inside the vehicle, then device complexity is reduced, but productivity deteriorates due to delayed vehicle preparation
Solution Approach 1:
The system activates vehicle functions in advance based on the key element's approach detected by satellite positioning, rather than waiting for the key element to be inside the vehicle. This preliminary activation prepares the vehicle ahead of time, improving productivity while maintaining manageable system complexity through remote sensing technology.
2Productivity
If vehicle functions are activated remotely based on key element position, then productivity is improved through early vehicle preparation, but loss of energy increases due to extended activation periods
Solution Approach 1:
The system dynamically adjusts vehicle function activation based on the key element's real-time position and movement characteristics. By monitoring the approach trajectory and calculating probability of use, the system optimizes activation timing to balance early preparation benefits against energy consumption, activating functions only when sufficiently probable that the vehicle will be used.
Solution Approach 2:
The system changes operational parameters (activation timing, duration, and intensity of vehicle functions) based on the key element's position and movement patterns. This allows optimization of energy consumption by adjusting when and how strongly functions are activated, rather than using fixed activation criteria.
3Reliability
If vehicle functions are activated based on probability calculations, then reliability is improved through optimized function selection, but device complexity increases due to additional calculation requirements
Solution Approach 1:
The system replaces complex mechanical or electronic probability calculation devices with software-based probability calculations performed by a processor. This substitution achieves reliable vehicle use prediction through algorithmic analysis of position data and movement characteristics, while keeping the physical device complexity manageable through the use of standard computing components.

AI summary
At least one vehicle and at least one key element, each associated with a corresponding vehicle, are configured to exchange data with one another via a system that determines the vehicle position and the position of the key element. The system places the vehicle in a driving operating mode when the vehicle position and the key element position are essentially the same, in particular when the key element is located inside the vehicle. At least one vehicle function that can be activated when the vehicle is stationary is automatically switched on depending on a current key element position. This may occur when a key element position is changing relative to the vehicle position, but the vehicle and the associated key element are remote from one another, such as separated by at least ten meters.
