Remote Parking Signal Conversion Using PDC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for remote control parking are costly and require advanced sensor technologies, making them inaccessible to medium and small vehicles, which need cost-effective alternatives for implementing remote control parking functionality.
Innovation Solution
Utilizing standard equipment like conventional Park Distance Control (PDC) to convert internal parking aid signals into external signals perceivable by the operator, allowing for remotely controlled parking maneuvers using a remote controller and existing vehicle infrastructure, including adaptations in signal properties for distance feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-quality sensor technologies (ultrasound, laser, radar, video) are used to implement fully remotely controlled parking, then the reliability and precision of the parking maneuver is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent uses the existing PDC system's signal processing capabilities to generate a virtual representation of distance information that can be transmitted externally. Instead of adding new sensors, the system copies and repurposes the signal processing functions of the existing PDC system to create external feedback signals, thereby avoiding additional hardware complexity while maintaining reliability
Solution Approach 2:
The patent makes the existing PDC system serve multiple functions: it continues to provide internal feedback to the driver while simultaneously generating external signals for remote operators. This multi-functionality eliminates the need for separate sensor systems, reducing device complexity while maintaining reliable parking assistance
2Ease of operation
If advanced sensor systems are installed in all vehicles for remote control parking, then the ease of operation for remote parking is improved, but the cost and manufacturing complexity increase
Solution Approach 1:
The existing PDC system serves itself by generating external feedback signals in addition to its primary internal feedback function. The system uses its own signal processing capabilities to create externally transmittable signals, eliminating the need for separate dedicated systems and reducing manufacturing complexity while maintaining ease of operation
3Ease of operation
If the first signal from the parking aid is converted into a second signal perceptible outside the vehicle, then the ease of operation for remote control parking is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a signal conversion function that acts as an intermediary between the internal PDC signal and the external feedback requirement. This intermediary uses the existing signal processing capabilities to transform the internal distance information into externally transmittable signals, facilitating ease of operation while avoiding direct addition of complex hardware

AI summary
Methods and devices assist in a parking maneuver of a vehicle. The vehicle includes a parking aid that produces a first signal. The first signal is perceptible in an interior of the vehicle during a parking maneuver. A signal property of the first signal is adapted to a currently prevailing distance of the vehicle from a parking obstruction. The first signal is converted into a second signal that is perceptible by an operator located outside the vehicle. The second signal is transmitted to the operator disposed outside the vehicle during a remotely-controlled performance of the parking maneuver.
