Vehicle Entry System Remote Positioning and Door Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing remote vehicle control systems require users to move around behind the vehicle to operate, which is inconvenient, especially in narrow spaces, as the vehicle moves away from the user when controlled remotely.
Innovation Solution
A vehicle entry system that includes a portable terminal and an in-vehicle device capable of wireless communication, featuring a door opening and closing unit and an in-vehicle control unit that authenticates the terminal and controls the vehicle's driving system and door operations, allowing the vehicle to be moved and parked in a position where the door can be easily accessed remotely, with icons on the terminal's touch panel for instructing the vehicle to advance or retreat to an openable position and open the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle is controlled to move away from the user through remote control, then the vehicle can be operated remotely, but the user must move around behind the vehicle to access the door, which reduces convenience
Solution Approach 1:
The vehicle automatically moves to a predetermined position where the door is accessible to the user before the user attempts to access it. The control unit receives information about the user's position and controls the vehicle to move accordingly, so that when the user reaches for the door, the vehicle is already in the correct position for easy access.
2Adaptability or versatility
If the vehicle moves away from the user during remote control, then remote operation is enabled, but the user cannot access the vehicle in narrow spaces where moving around the vehicle is impossible
Solution Approach 1:
The system determines the user's position relative to the vehicle and automatically controls the vehicle to move to a position where the door is accessible, even in narrow spaces where the user cannot move around the vehicle. This preliminary positioning action ensures the vehicle is in the correct location before the user attempts to enter.
Solution Approach 2:
The system replaces the mechanical requirement for the user to physically move around the vehicle with an automated electronic control system. The control unit receives position information and automatically adjusts the vehicle's position through electronic control, substituting the need for manual physical movement with automated electronic positioning.
3Extent of automation
If the vehicle door is opened while the vehicle is in an inaccessible position, then the door can be opened remotely, but the user still cannot easily access the vehicle
Solution Approach 1:
The control unit receives information about the user's position and automatically controls the vehicle to move to a predetermined position where the door is accessible before opening the door. This ensures that when the door is opened, the user is in the correct position to easily access the vehicle.
Solution Approach 2:
The system uses feedback from position information about the user relative to the vehicle to automatically adjust the vehicle's position. The control unit continuously monitors the user's position and controls the vehicle to move accordingly, ensuring optimal positioning for door access before the door opening operation is completed.

AI summary
A vehicle entry system that comprises a portable terminal and an onboard device that wirelessly communicates with the portable terminal. The onboard device has: a door opening and closing unit that can lock a vehicle door in a closed state and open the vehicle door to a prescribed angle; and an onboard control unit that, on the basis of commands from a portable terminal, controls a vehicle drive system and the door opening and closing unit. The portable terminal has a touch panel and a terminal control unit that outputs commands to the onboard control unit. A plurality of icons on the touch panel include an advance-and-open-door icon to advance to a location at which the door can open and, after advancing, to open the door; and a reverse-and-open-door icon to reverse to a location at which the door can open and, after reversing, to open the door.
