Remote Parking Door Angle Pause Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During remote parking operations into narrow spaces, occupants are often forced to exit the vehicle prematurely due to doors being unable to open sufficiently, exposing them to adverse weather conditions.
Innovation Solution
A vehicle system that determines the minimum open door angle for each occupant and pauses the remote parking operation when a door can no longer safely open to this angle, allowing the occupant to exit before resuming the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle executes remote parking operation into a narrow parking spot, then the vehicle can be positioned in the parking spot, but the door is prevented from opening to the minimum open door angle
Solution Approach 1:
The system performs preliminary assessment of the parking space dimensions before executing the remote parking operation. It calculates the minimum open door angle required and determines the optimal pause point in the parking trajectory where the door can still open sufficiently. This preliminary planning allows the vehicle to pause at the correct position, enabling occupants to exit before the door opening becomes impossible.
2Object-affected harmful factors
If the vehicle pauses remote parking operation to allow occupant exit, then occupant safety and comfort are improved, but the remote parking operation time is increased
Solution Approach 1:
The system pre-calculates the optimal pause point during the remote parking trajectory where the door can still open to the minimum required angle. By pausing at this precisely determined position rather than continuously monitoring and reacting, the system minimizes the total pause time while ensuring occupant safety. This preliminary planning of the pause point optimizes the balance between occupant protection and operation efficiency.
Solution Approach 2:
The system automatically determines when to pause and resume the remote parking operation based on pre-calculated geometric constraints and real-time door angle sensing. The pause decision is made autonomously by the vehicle's control system without requiring external intervention, efficiently managing the trade-off between occupant safety and operation time.
3Ease of operation
If the vehicle determines minimum open door angle and monitors door position, then occupant exit capability is ensured, but the system complexity is increased
Solution Approach 1:
The system incorporates sensors to monitor the actual door angle during the remote parking operation and compares it against the pre-calculated minimum required angle. This feedback mechanism allows the system to verify whether the door can open sufficiently at the current vehicle position and to make real-time decisions about pausing the operation. The feedback loop ensures occupant exit capability while maintaining relatively simple control logic.

AI summary
Vehicles and methods are disclosed for enabling vehicle occupants to maximize their time inside a vehicle during a remote parking operation, so as to limit exposure to adverse weather. An example vehicle includes a door, a sensor, and a processor. The processor is configured to determine a minimum open door angle for an occupant to exit, determine a vehicle path for execution of a remote parking operation, and, responsive to determining via the sensor during execution of the remote parking operation that the door is prevented from opening to the minimum door angle, pause execution of the remote parking operation.
