Remote Parking Assistance via Intermediary Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote parking systems face challenges when an operator leaves the vehicle before completing a parking or unparking event, leading to potential safety hazards as the vehicle may be left in an unsafe location due to loss of communication between the vehicle and the operator's device.
Innovation Solution
A method and system that utilize vehicle sensors, actuators, and a communication system to establish a connection with a remote assistance center, allowing automated control of the vehicle to complete the parking or unparking maneuver by determining a projected parking path and avoiding obstacles, even if the operator is no longer present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator leaves the vehicle before completing a parking or unparking event, then the operator can move freely, but the vehicle may be left in an unsafe location due to loss of communication
Solution Approach 1:
The patent introduces a remote assistance center as an intermediary between the operator and the vehicle. When the operator leaves the vicinity and communication is lost, the remote assistance center receives sensor data from the vehicle, determines a projected parking path, and provides automated control signals to complete the parking maneuver safely, preventing the vehicle from being left in an unsafe location
Solution Approach 2:
The vehicle system automatically detects when communication is lost and initiates a connection to the remote assistance center. The system then autonomously transmits sensor data and receives control signals to complete the parking maneuver without requiring the operator to be present, enabling the vehicle to service itself in completing the parking task
2Object-affected harmful factors
If the vehicle enters failsafe mode upon communication loss, then safety is prioritized by stopping the vehicle, but the parking event remains incomplete and the vehicle may block traffic or neighboring vehicles
Solution Approach 1:
The remote assistance center determines a projected parking path before the vehicle completes the maneuver. By pre-planning the safe parking trajectory based on sensor data, the system ensures that the vehicle can complete the parking event without entering failsafe mode, avoiding both safety hazards and incomplete operations
Solution Approach 2:
The system continuously monitors communication status and vehicle sensor data. When communication is lost, the remote assistance center receives real-time sensor data from the vehicle, evaluates the situation, and provides feedback control signals to guide the vehicle to complete the parking maneuver safely, preventing both safety hazards and incomplete operations
