Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic parking assistance systems face degraded sensing accuracy for objects around the vehicle during un-parking, leading to potential collisions.
Innovation Solution
An apparatus and method that utilize sensors to confirm the position of a driver and objects around the vehicle, calculating an un-parking trace based on the positions of these objects to control the vehicle's steering angle and speed for safe un-parking, including modes for right-angled and parallel un-parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic parking assistance system is used for un-parking, then parking guidance is provided, but sensing accuracy of objects around the vehicle is degraded causing potential collisions
Solution Approach 1:
The system performs preliminary sensing of objects around the vehicle before initiating un-parking, and determines the driver's position in advance. This allows the control module to plan a safe un-parking trajectory that avoids collisions while maintaining automated guidance functionality.
Solution Approach 2:
The system continuously monitors the positions of objects around the vehicle and the driver's position during un-parking, providing feedback to the control module which adjusts the un-parking control signals accordingly. This closed-loop control maintains safety while enabling automated parking assistance.
2Measurement precision
If sensor-based object detection is used, then objects around the vehicle are detected, but driver position confirmation is insufficient leading to unsafe un-parking
Solution Approach 1:
The sensor module performs multiple functions: it detects objects around the vehicle and simultaneously determines the driver's position based on the manipulation device position. This multi-functional approach ensures both object detection accuracy and driver position confirmation are achieved using the same sensing system.
Solution Approach 2:
The manipulation device position serves as an intermediary indicator for driver position. Instead of directly tracking the driver, the system uses the position of the manipulation device (which the driver operates) as a proxy to infer driver location and intent for un-parking.
3Ease of operation
If un-parking control is automated, then un-parking operation is simplified, but collision risk increases due to degraded sensing accuracy
Solution Approach 1:
The control module calculates the un-parking trajectory in advance based on pre-acquired position information of objects and the driver. This preliminary planning ensures collision avoidance is built into the automated operation before execution, maintaining both ease of operation and reliability.
Solution Approach 2:
The system continuously monitors object positions and driver position during automated un-parking, providing real-time feedback to adjust the trajectory. This ensures the automated operation remains safe and reliable while maintaining ease of operation through automated control.

AI summary
An apparatus for controlling un-parking of a vehicle includes: a sensor module configured to include at least one sensor that receives an un-parking request signal for a parked vehicle and determines whether a first object around the vehicle is present; and a control module configured to determine a position of a second object based on the un-parking request signal and determine whether the vehicle is un-parked depending on positions of the first object and of the second object to control the un-parking of the vehicle.
