Solution Overview

Problem

Existing e-corner module technologies do not address the inconvenience drivers face when entering or exiting a vehicle, especially in tight spaces, despite enhancing driving convenience through wide steering angles.

Innovation Solution

A system and method for vehicle steering that allows remote control of vehicle corner modules using a user terminal, enabling independent wheel steering and various driving modes, including crab, pivot turn, and zero turn, even when the terminal is dismounted, with features like departed driver rescue & exit maneuver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If e-corner module is used to enable wide steering angle for crab driving and zero turn driving, then driving convenience and space utilization are improved, but driver accessibility for entering/exiting vehicle deteriorates in tight spaces

Engineering Contradiction:
Improvedriving mode versatilityVSAvoiddriver accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces an automated driving system as an intermediary that takes over vehicle control when the driver needs to enter or exit in tight spaces. The system autonomously performs maneuvers such as crab driving, zero turn driving, and position adjustment to create sufficient clearance for driver access, thereby resolving the contradiction between advanced driving capabilities and driver accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If vehicle performs crab driving to park in narrow space, then parking capability is improved, but driver exit space may become insufficient

Engineering Contradiction:
Improveparking capabilityVSAvoiddriver exit space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The system performs preliminary actions by autonomously executing crab driving and zero turn driving maneuvers before the driver attempts to exit. It proactively creates sufficient exit space by adjusting vehicle position and orientation in advance, ensuring that driver accessibility is maintained even after parking in narrow spaces.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If remote control of corner module is implemented through user terminal, then driver accessibility in tight spaces is improved, but system complexity increases

Engineering Contradiction:
Improvedriver accessibilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system implements self-service by autonomously monitoring driver accessibility conditions and automatically executing corrective maneuvers when needed. The automated driving system detects when driver exit or entry is difficult and independently performs crab driving, zero turn driving, or position adjustment without requiring complex manual intervention or additional control interfaces.

Inventive Principle:
Principle #25Self-service
