Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote operation systems perform fail-safe operations uniformly regardless of the user's proximity to the vehicle, leading to inconvenient, slow, and inefficient remote operations.
Innovation Solution
A vehicle remote operation device that adjusts fail-safe criteria based on the distance between the user and the vehicle, optimizing fail-safe operations by reducing unnecessary steps when the user is closer, using GPS and Smart Entry Systems to determine awareness and proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform fail-safe operations are performed regardless of user proximity, then safety is ensured, but operation convenience and response time deteriorate
Solution Approach 1:
The fail-safe criterion is dynamically adjusted based on the detected distance between the user and vehicle. When the user is close to the vehicle, the system reduces the number of fail-safe operations compared to when the user is far away. This dynamic adaptation resolves the contradiction by making the safety level proportional to the actual risk, thereby improving operation convenience without compromising essential safety.
Solution Approach 2:
The system changes the parameter of fail-safe criterion (number and type of fail-safe operations) based on the distance parameter. By modifying the fail-safe criterion according to user proximity, the system achieves both safety (through appropriate fail-safe measures) and convenience (by reducing unnecessary operations when the user is nearby).
2Reliability
If uniform fail-safe operations are performed regardless of user proximity, then safety is ensured, but response time deteriorates
Solution Approach 1:
The system dynamically adjusts the fail-safe criterion based on real-time distance detection. When the user is close to the vehicle, fewer fail-safe operations are executed, reducing the response time. When the user is far away, more comprehensive fail-safe operations are performed to ensure safety. This dynamic approach resolves the time-safety contradiction.
Solution Approach 2:
The fail-safe criterion parameter is changed according to the distance parameter. By adjusting the number and type of fail-safe operations based on user proximity, the system reduces unnecessary time consumption while maintaining appropriate safety levels for each situation.
3Reliability
If comprehensive fail-safe operations are performed, then safety is improved, but device complexity and operation steps increase
Solution Approach 1:
The system applies different levels of fail-safe operations based on the local condition of user proximity. Instead of uniformly applying comprehensive fail-safe operations everywhere, the system locally adapts the fail-safe criterion to match the actual risk level. When the user is close, simpler fail-safe measures are applied; when far, more comprehensive measures are used. This resolves the contradiction between safety and complexity.
Solution Approach 2:
The fail-safe criterion parameter is adjusted based on the distance parameter, changing the number and type of fail-safe operations required. This parameter adaptation allows the system to maintain high safety standards when necessary while reducing operational complexity when the user is nearby and risk is lower.

AI summary
A vehicle remote operation device of optimized fail-safe function is disclosed that directs a vehicle to execute operations in response to a remote operation request made by a user of the vehicle. The vehicle remote operation device has a fail-safe control unit that changes a fail-safe criterion in execution of the remote operation according to a distance between the user and the vehicle. Preferably, the fail-safe criterion is moderated when the distance between the user and the vehicle is short. Alternatively, instead of measuring the distance between the user and the vehicle, a Smart Entry System is used to detect a key carried by the user to determine whether the user is near the vehicle.
