Parking Assist Apparatus Technique Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assist systems provide unnecessary assistance to drivers who do not require it, leading to user frustration and inefficient operation, as they are activated whenever the vehicle is put in reverse, regardless of the driver's need for assistance.
Innovation Solution
A microcomputer-based parking assist apparatus that determines the actual parking technique used by the driver and compares it to a model technique, only providing assistance when the driver accepts help and when the techniques differ, allowing for personalized assistance based on the user's skills and parking lot conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parking assistance is executed whenever the driver moves the gearshift to reverse, then the driver can receive help in parking operations, but unnecessary assistance is provided to drivers who do not require it, leading to user frustration and deactivation of the system
Solution Approach 1:
The system monitors the driver's parking operations and compares actual techniques with model techniques to detect when assistance is truly needed. This feedback mechanism allows the system to adapt to the driver's actual skill level and parking situation, providing assistance only when the driver's technique deviates from the model, thereby resolving the contradiction between providing help and avoiding unnecessary interference.
Solution Approach 2:
The parking assistance system transitions from a static, always-active state to a dynamic, condition-responsive state. By continuously evaluating the driver's actual parking technique against the model technique and responding only when differences are detected, the system dynamically adjusts its level of involvement, providing assistance adaptively rather than uniformly.
2Reliability
If parking assistance is always active, then the driver can receive help in difficult parking situations, but the system becomes troublesome and drivers deactivate it
Solution Approach 1:
The system uses feedback from monitoring the driver's parking technique to determine when assistance is appropriate. By comparing actual parking operations with model operations and only providing assistance when differences are detected, the system maintains reliability by offering help when needed while avoiding unnecessary interference that would bother the driver.
Solution Approach 2:
The system allows skilled drivers to park independently without interference, only activating assistance when the driver's technique deviates from the model. This self-service approach lets competent drivers operate autonomously while still providing a safety net for those who need help, thereby maintaining both reliability and ease of use.
3Loss of energy
If the system asks whether assistance is desired only when techniques differ, then unnecessary assistance is prevented, but the system complexity increases due to technique comparison
Solution Approach 1:
The system creates a model technique representing ideal parking operations and compares the driver's actual technique against this model. By using a standardized model as a reference, the system can efficiently determine when assistance is needed without complex real-time analysis, reducing the computational burden while still preventing unnecessary assistance.

AI summary
In a case where an actual parking technique of a driver in a parking condition is different from a parking technique shown by a parking technique model generated in a same parking condition, a parking assist apparatus outputs a question to the user about whether or not assistance for the parking operation is desired to park the vehicle. In a case where the driver accepts the assistance for the parking operation, the parking assist apparatus provide the assistance for the parking operation to park the vehicle. Thus, useless parking assistance that the driver does not desire can be prevented, and parking assistance that is truly desired by the driver can be executed.
