Parking Assist Device Angle Correction Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance systems face difficulties in guiding vehicles to a target parking position when the angle of the current position with respect to the target position is not within an appropriate range, even if the vehicle is within a rearward-movement start position.
Innovation Solution
A system that determines when a host vehicle reaches a rearward-movement start position and assesses whether the angle with respect to the target parking position is appropriate, issuing instructions for correction if necessary, to facilitate guidance to the target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional parking assistance apparatus guides the host vehicle to a rearward-movement start position, then the driver's burden of moving to the start position is reduced, but if the angle at the current position is not within an appropriate range, subsequent guidance to the target parking position becomes difficult
Solution Approach 1:
The determining section performs preliminary assessment of the angle between the host vehicle's current position and the target parking position before initiating rearward movement. This preliminary action ensures that the vehicle is properly oriented for successful parking guidance, preventing situations where the vehicle reaches the start position but cannot complete the parking maneuver due to improper angle.
Solution Approach 2:
The system implements feedback by continuously monitoring the angle between the host vehicle and target parking position, and providing guidance instructions to the driver to correct the angle if it is not within the appropriate range. This feedback loop ensures that the vehicle maintains the correct orientation for successful parking guidance throughout the maneuver.
2Productivity
If the host vehicle reaches the rearward-movement start position without angle correction, then the parking process can proceed quickly, but the guidance to target parking position may fail if the angle is inappropriate
Solution Approach 1:
The system performs preliminary angle assessment and correction guidance before the host vehicle reaches the rearward-movement start position. By checking and correcting the angle in advance, the system ensures that when the vehicle does reach the start position, the subsequent guidance to the target parking position will succeed, thus maintaining both speed and reliability.
Solution Approach 2:
The determining section anticipates potential guidance failure by preemptively checking the angle condition and issuing correction instructions before the vehicle reaches the critical rearward-movement start position. This preliminary anti-action prevents the harmful outcome of failed guidance while minimizing the impact on parking maneuver speed.

AI summary
Provided is a parking assist device such that, when a vehicle has reached an area corresponding to a backing start position, the angle of a current position with respect to a target parking position is placed in an appropriate range so as to facilitate subsequent guidance to the target parking position. In the parking assist device, when a vehicle (601) has reached any of a plurality of backing start positions (603 to 605), a state control unit (112) determines whether the angle of a current position with respect to a target parking position (602) is appropriate for guidance to a target parking position (602), and, if not, displays an angle correction indicating icon (606) on an image display means (102) to provide an indication for correcting the angle.
