Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote parking systems face significant merchantability issues due to interference from radio wave-generating facilities and noise sources, leading to unreliable detection of smart keys and potential cessation of parking assistance control.
Innovation Solution
A remote parking assistance device that adjusts assistance modes and vehicle control based on the detection distance of the smart key, using sensors and smart antennas to specify detection distances and limit assistance modes when interference is present, ensuring continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio wave intensity threshold T1 is used to determine parking assistance execution, then parking assistance can be executed in normal conditions, but parking assistance control stops when radio wave intensity is less than T1 due to interference from radio wave-generating facilities
Solution Approach 1:
The patent applies dynamics by making the assistance mode executable dynamically adjustable based on detection distance. When the detection distance is within the predetermined range (indicating interference from radio wave facilities), the system dynamically switches to an executable assistance mode that allows remote parking operations despite reduced radio wave intensity, rather than completely stopping the control function.
Solution Approach 2:
The patent changes the parameter of assistance mode execution status based on the detection distance parameter. When detection distance indicates interference conditions, the system changes from a non-executable state (when radio wave intensity < T1) to an executable state with modified assistance modes, allowing continuous operation under different operational parameters.
2Measurement precision
If detection distance is reduced due to radio wave interference, then smart key detection becomes unreliable, but remote parking operation should remain possible
Solution Approach 1:
The system dynamically adjusts the assistance mode based on the detected distance to the smart key. When interference reduces detection precision, the system transitions to an executable assistance mode that maintains operational reliability through alternative control mechanisms, allowing remote parking to continue despite reduced detection precision.
Solution Approach 2:
The executable assistance mode acts as an intermediary mechanism between the smart key detection system and the remote parking control system. When detection precision is compromised by interference, this intermediary mode enables continued operation by providing alternative control pathways that do not solely depend on high-precision smart key detection.
3Reliability
If parking assistance control is stopped when radio wave intensity is less than T1, then detection reliability is maintained, but merchantability of remote parking deteriorates remarkably
Solution Approach 1:
Instead of statically stopping control when radio wave intensity < T1, the system dynamically adjusts the assistance mode to an executable state when detection distance indicates interference conditions. This maintains service availability while adapting to reduced detection reliability through modified operational modes.
Solution Approach 2:
The patent converts the harmful effect of radio wave interference (reduced detection reliability) into a beneficial operational adaptation by enabling executable assistance modes. Rather than viewing reduced detection reliability as a reason to stop service, the system uses this condition to activate alternative operational modes that maintain productivity and service availability.

AI summary
In the remote parking assistance device, the assistance mode that can be executed in the remote parking assistance control is limited according to a detection distance that is a distance at which the presence or absence of a smart key can be detected by the vehicle system. Specifically, as the detection distance becomes shorter, the number of support modes that cannot be selected by the operator using the remote control terminal and/or the number of support modes in which remotely operated terminals alert the operator is increased.
