Wireless Vehicle Component Adjustment with Intermediate Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle adjusting systems require additional actuation to pause movement at intermediate positions, limiting ease of use and convenience when using mobile communications devices for adjusting components like hatches or garage doors.
Innovation Solution
A system that allows wireless control of adjustable components using mobile communications devices to select and move to specific target positions, including intermediate positions, without needing a stop command, using an electric motor drive with spindle mechanism, and enabling voice, key, or touch input for position selection, with visual and acoustic feedback for confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile communications device is used to control an adjustable component, then ease of operation is improved, but additional actuation is required to pause movement at intermediate positions
Solution Approach 1:
The system stores multiple predetermined target positions in advance. When the user activates a stored target position, the component moves directly to that position without requiring intermediate stop commands. This preliminary preparation of target positions eliminates the need for additional actuation during movement.
Solution Approach 2:
The system provides feedback signals to confirm when the adjustable component has reached the desired intermediate position. This automatic position confirmation eliminates the need for continuous user actuation and provides clear indication that the movement pause is achieved.
2Ease of operation
If intermediate positions are used as target positions, then ease of operation is improved, but the system complexity increases
Solution Approach 1:
The control system is designed to handle both basic positions and intermediate positions through a unified target position selection mechanism. The same interface and control logic are used regardless of whether the target is a basic or intermediate position, avoiding the need for separate control systems.
Solution Approach 2:
The system automatically manages the distinction between basic and intermediate positions. When a user selects a target position, the system independently determines whether it is basic or intermediate and executes the appropriate movement and pause logic without requiring user classification or additional input.
3Ease of operation
If stepless movement to selected positions is enabled, then ease of operation is improved, but measurement precision requirements increase
Solution Approach 1:
The system employs feedback mechanisms including position sensors and obstacle detection sensors that continuously monitor the adjustable component's position and environment. This feedback enables the control unit to make precise adjustments during stepless movement and accurately determine when the target position is reached.
Solution Approach 2:
The system dynamically adjusts movement parameters during operation. The control unit can modify speed, acceleration, and stopping criteria based on real-time feedback from sensors, enabling flexible stepless movement while maintaining positioning accuracy through adaptive control.

Implementation Method 1
A particularly suitable drive is an electric motor drive
Implementation Method 2
The drive can have a spindle drive that is drivable by an electric motor and through which the hatch can be movably driven to the selected target position

AI summary
An adjusting system for adjusting a component of a motor vehicle on an adjustment path between a basic position and an end position with a mobile communications device through which control commands can be sent wirelessly to a control unit arranged in the motor vehicle and through which a drive for the adjustment of the adjustable component can be actuated. A target position selected from a plurality of target positions on the adjustment path of the adjustable component can be entered in the mobile communications device, and thereupon a corresponding actuating signal can be sent to the control unit wirelessly through the mobile communications device. The drive for adjusting the adjustable component to the selected target position can be actuated by the control unit.
