Solution Overview

Problem

Existing vehicle control systems struggle to provide suitable exiting assistance from parking positions due to potential discrepancies between the path obtained by reversing the entering path and the desired exiting path, and may include paths that are impossible to traverse, making it difficult to use the reversed path effectively.

Innovation Solution

A vehicle control method that includes registering an exiting path based on occupant operation, prompting registration through a display device, and allowing the vehicle to travel and register the path from the parking position to the target exiting position, integrating sensors, operation devices, and display devices to facilitate autonomous travel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a path obtained by reversing the traveling path until the vehicle performs entering in the parking position is used as the exiting path, then the vehicle can perform autonomous exiting, but the exiting path may be different from the desired path or include impossible partial paths

Engineering Contradiction:
Improveautonomous exitingVSAvoidexiting path accuracy
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The system performs preliminary path registration during the entering phase, storing the actual traveling path taken by the occupant. This pre-registered path is then reused during exiting operations, eliminating the need to recalculate the path and ensuring consistency between entering and desired exiting paths.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the traveling path data recorded during entering and applies it during exiting operations. This copying mechanism ensures that the same reliable path information is used for both entering and exiting, avoiding the reliability issues of real-time path reversal.

Inventive Principle:
Principle #26Copying

2Ease of operation

If the exiting path is automatically generated by reversing the entering path, then the system can provide exiting assistance, but the path may not match the occupant's desired route

Engineering Contradiction:
Improveexiting assistanceVSAvoidpath customization
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system incorporates feedback mechanisms where the occupant can review the registered exiting path and provide corrections or adjustments. The system learns from these adjustments and refines the path registration process, ensuring future paths match occupant preferences while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adapts the exiting path based on registered data and occupant preferences. Rather than using a static reversal method, the system updates and refines path information over time, allowing the path to evolve and better match occupant needs while maintaining automatic generation capabilities.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the system prompts the occupant to register the exiting path, then the path accuracy improves, but additional time and operations are required

Engineering Contradiction:
Improveexiting path accuracyVSAvoidpath registration time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system merges the path registration process with the normal entering operation. While the occupant is already driving the vehicle into the parking position, the system simultaneously records the path data. This combines two operations into one, improving path accuracy without adding separate registration time.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs path registration in advance during the entering phase, so that when exiting is needed, the path is already prepared and stored. This preliminary action eliminates the need for time-consuming path registration at the moment of exiting, reducing time loss while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action

AI summary

A vehicle control method includes: controlling at least steering to cause a vehicle to perform autonomous traveling from a parking position to a target exiting position based on an exiting path in a case where the exiting path from the parking position to the target exiting position has been registered when starting exiting from the parking position; causing the display device to display first information prompting an occupant to determine whether or not to register the exiting path in a case where the exiting path has not been registered when starting the exiting from the parking position; and causing the vehicle to travel from the parking position to the target exiting position according to the operation by the occupant, and registering, as the exiting path, a traveling path along which traveling has been performed from the parking position to the target exiting position.
