Unified Vehicle Parking HMI for Garage Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic parking systems for vehicles do not seamlessly integrate with remotely controlled access systems, such as garage doors, requiring separate interfaces for parking and access operations.
Innovation Solution
An onboard vehicle system that combines an automatic parking unit with a communication circuit for wireless operation of remotely controlled access systems, and a human machine interface (HMI) for unified control of both parking and access operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate interfaces are used for parking and access operations, then each function can be independently controlled, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent combines the parking control interface and access system control interface into a single unified HMI. The HMI includes a parking button that simultaneously controls the automatic parking unit and sends wireless instructions to operate the access system (garage door, gate, or barrier). This merging eliminates the need for separate interfaces, reducing device complexity while improving ease of operation through unified control.
Solution Approach 2:
The HMI is designed as a universal interface that performs multiple functions: it controls the automatic parking maneuver and simultaneously operates the access system. The single HMI structure with integrated buttons provides multi-functional control, allowing the user to manage both parking and access operations through one interface rather than requiring separate dedicated interfaces for each function.
2Loss of time
If separate control systems are used for parking and access operations, then functional independence is maintained, but the loss of time increases due to multiple operations
Solution Approach 1:
The patent merges the control of parking operations and access system operations into a single HMI with integrated buttons. When the parking button is actuated, it simultaneously triggers the automatic parking unit and sends wireless instructions to operate the access system. This concurrent control through a unified interface eliminates the time loss associated with sequential operations while avoiding increased device complexity.
Solution Approach 2:
The HMI is pre-configured to send wireless instructions to the access system in advance or simultaneously with the parking maneuver initiation. The button is designed to trigger both the automatic parking sequence and the access system operation (such as opening a garage door) at the appropriate time, eliminating delays that would occur if the user had to manually operate each system separately.

AI summary
An onboard automatic parking system for a vehicle comprises: an automatic parking unit (20) suited to control a maneuver of the vehicle in or out of a park area secured by a remotely controlled access system; a communication circuit (14) suited to send a wireless instruction for operating the access system; and a human machine interface (30) suited to monitor the communication circuit (14) to send the wireless instruction upon actuation of the human machine interface (30), wherein the human machine interface (30) is also suited to command the automatic parking unit (20) that controls the maneuver subsequent to actuation of said human machine interface (30).
