Vehicle Control Device for Obstacle-Avoiding Parking Path Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated parking systems do not allow drivers to accurately determine whether they can avoid obstacles like puddles or muddy areas without changing the desired parking space, and they fail to ensure the vehicle parks in the intended space.
Innovation Solution
A vehicle control device that uses external environment sensors to recognize a movement capable region, displays this region, and allows users to select a desired parking space, generating and correcting a parking movement path to avoid obstacles within the selected space without changing the parking space, using a pointing unit to instruct path corrections.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the conventional parking assist device changes the desired parking space to avoid obstacles, then the vehicle can avoid travel through avoidance locations, but it cannot satisfy the intention of the vehicle occupant to park in a desired parking space
Solution Approach 1:
The system dynamically adjusts the movement path within the selected parking space based on detected obstacles. The action planning unit regenerates the movement path in real-time to avoid puddles or muddy areas while keeping the parking space selection fixed, allowing the path to be flexible while the destination remains static.
Solution Approach 2:
The system separates the parking space selection function from the movement path planning function. The display unit shows the selected parking space independently, while the action planning unit independently generates and adjusts the movement path, allowing modifications to the path without changing the selected parking space.
2Loss of information
If the conventional parking assist device does not display the parking movement path, then the device complexity is reduced, but the driver cannot accurately determine whether travel through avoidance location can be avoided
Solution Approach 1:
The display unit serves as an intermediary between the action planning unit and the driver. It visually presents the movement path and parking space information, enabling the driver to understand and verify the planned path without adding complex control mechanisms.
Solution Approach 2:
The system provides visual feedback by displaying the movement path on the display unit. This allows the driver to see the planned path, verify obstacle avoidance, and understand the vehicle's intended movements, creating a feedback loop that enhances driver awareness and trust.

AI summary
A movement path is regenerated within a movement capable region in accordance with an instruction to correct a movement path by a pointing unit, and the regenerated movement path is displayed on a display unit in a superimposed manner on a movement capable region for a user's own vehicle. As a result, without changing a parking space (position) in which a vehicle occupant desires to park, it is possible for parking to be performed along the desired movement path to the desired parking space.
