Assisted Parking Device with Dual Trajectory Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-autonomous parking systems require the vehicle to be driven completely past the parking space for measurement, leading to confusion among other road users and complex maneuvers to reach an optimal starting position for guided parking.
Innovation Solution
A device that determines and displays two possible movement paths, allowing the driver to select a favorable trajectory without fully passing the parking space, enabling guided parking by a semi-autonomous system, with options for left-turn or straight-ahead paths to avoid oncoming traffic and simplify the parking process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle is driven completely past the parking space for measurement, then the parking space can be measured completely by the parking system, but other road users may be confused and the driver must perform complex shunting maneuvers to reach an advantageous starting position
Solution Approach 1:
The system performs preliminary measurement of the parking space using sensor devices before the driver needs to position the vehicle for parking. The measurement is completed in advance while the vehicle is approaching the parking space, so that when the driver needs to maneuver, the measurement data is already available and no additional complete passing maneuver is required.
Solution Approach 2:
The patent introduces a control device that acts as an intermediary between the sensor arrangement and the driver. This control device processes sensor data to determine advantageous starting positions and provides guidance information to the driver, eliminating the need for the driver to perform complex shunting maneuvers while ensuring complete parking space measurement.
2Measurement precision
If the vehicle is driven completely past the parking space, then the parking space can be measured, but the starting position for activating the semi-autonomous parking system is not advantageous
Solution Approach 1:
The measurement of the parking space is performed in advance using sensor devices while the vehicle is approaching, so that when the driver reaches the determined advantageous starting position, all measurement data is already available and no additional time-consuming shunting maneuvers are required.
Solution Approach 2:
The control device continuously receives sensor data and provides feedback to the driver about the current vehicle position relative to the parking space and the advantageous starting position. This feedback mechanism allows the driver to understand when to stop and activate the parking system, eliminating time wasted on trial-and-error maneuvers.
3Measurement precision
If the driver guides the vehicle completely past the parking space, then the parking system can obtain measurement information, but the driver has limited options for reaching optimal starting positions
Solution Approach 1:
The system dynamically determines multiple advantageous starting positions based on real-time sensor data and vehicle position. Instead of requiring the driver to find a single fixed starting position through trial-and-error maneuvers, the system calculates and communicates multiple valid starting positions that can be reached through simpler, more direct paths, increasing adaptability to different driving situations.

AI summary
The invention relates to a device for the assisted parking of a vehicle (10), particularly of a motor vehicle, in a parking space (11) located transversal to the vehicle (10), comprising at least one sensor device (18) designed for at least detecting the parking space (11), and comprising a display means by which a movement path (12, 13) on which the vehicle (10) can be moved can be displayed to a driver of the vehicle (10). According to the invention, the device is designed to determine at least two possible movement paths (12, 13) on which the vehicle (10) can be moved by the driver into a starting position (12a, 13a), from which the vehicle (10) can be moved into the parking space (11) by at least one subsequent parking move guided by a parking device.
