Parking Target Position Adjustment via Dynamic Input and Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems lack the ability for drivers to easily adjust and fine-tune the target parking position, particularly in restricted spaces, and do not provide intuitive feedback on the vehicle's positioning relative to obstacles, leading to potential collisions and inefficient parking maneuvers.
Innovation Solution
A method that allows drivers to shift and rotate the target parking position using an input unit, with visual feedback and guidance, and automatic driving assistance to ensure accurate positioning, utilizing sensors for environment modeling and display of possible movements, and automatic deactivation of support when the target is reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a computer-calculated target position is used for parking assistance, then the parking maneuver is automated and easy to execute, but the driver cannot adjust the position to account for individual wishes such as trunk access or passenger exit space
Solution Approach 1:
The target position is made dynamically adjustable by the driver through an input unit (joystick or direction keys) after the initial computer calculation. The driver can shift the position in horizontal and vertical directions and rotate it around the vehicle center, allowing real-time adaptation to personal needs while maintaining the automated guidance framework.
Solution Approach 2:
The system provides visual feedback by displaying the target position and the adjustable area frame on a display unit. This feedback loop allows the driver to see the current target position, understand the adjustable range, and make informed adjustments before executing the parking maneuver.
2Ease of operation
If the target position is fixed without adjustment capability, then the system is simple to operate, but the driver receives no direct feedback on how the vehicle will be positioned relative to obstacles
Solution Approach 1:
The display unit shows the target position overlaid on the bird's-eye view of the vehicle environment, providing the driver with direct visual feedback on where the vehicle will be positioned relative to detected obstacles and the surrounding area. This eliminates information loss by making the target position transparent to the driver.
Solution Approach 2:
The system uses an intermediate visual representation (graphic display of target position and environment) as a mediator between the automated positioning system and the driver. This intermediary visualization allows the driver to understand the relationship between the target position and physical obstacles without complex calculations.
3Adaptability or versatility
If the driver can freely adjust the target position without constraints, then individual preferences can be fully accommodated, but the vehicle may be positioned in unreachable or unsafe locations
Solution Approach 1:
The system preemptively prevents unsafe or unreachable target positions by implementing boundary checks and validation before the parking maneuver begins. The adjustable area frame and system logic ensure that adjustments remain within safe, reachable limits, eliminating the need for corrective actions during execution.
Solution Approach 2:
The system provides feedback to the driver when the target position is unreachable or unsafe, preventing adjustment to invalid positions. This feedback mechanism maintains reliability by guiding the driver to make only valid adjustments within the computable reachable area.
4Adaptability or versatility
If manual positioning adjustment is added to the automated system, then driver preferences can be accommodated, but the system complexity increases
Solution Approach 1:
The input unit serves multiple functions: it allows driver preference input for target position adjustment, provides control for parking maneuver execution, and interfaces with the automated guidance system. This multi-functionality reduces overall system complexity by consolidating controls rather than adding separate dedicated components for each function.
Solution Approach 2:
The driver performs the adjustment function themselves using the input unit, eliminating the need for complex automated detection of driver intent or additional sensors. The system provides the tools for self-adjustment, maintaining simplicity while enabling adaptability.

AI summary
Disclosed is a driving assistance method for a vehicle (1), in which the surroundings of the vehicle are detected by means of sensors and are represented at least in part in a display unit (19). A target position (25) of the vehicle is registered in the surroundings of the vehicle. Said target position can be displaced (27, 28, 29, 30) and/or rotated (36) in the representation of the surroundings of the vehicle with the aid of an input unit (32). Driving indications for steering the vehicle to the target position can be output to the driver while at least one driving function (e.g. steering) can be controlled automatically.
