Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual steering operations are used, then the driver has direct control over the vehicle, but the operation complexity increases and safety decreases

Engineering Contradiction:

Improvesteering operation simplicityVSAvoidsteering control complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent creates a virtual vehicle model that replicates the physical vehicle's steering behavior. The virtual vehicle receives simplified touch inputs and automatically translates them into complex steering commands, allowing the driver to control the physical vehicle through a simplified virtual interface without directly manipulating complex steering mechanisms

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The virtual vehicle serves as an intermediary layer between the driver's simple touch input and the physical vehicle's steering system. It translates intuitive gestures into precise steering angle commands, mediating between user intent and vehicle response while reducing operational complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If manual steering operations are used, then the driver can control the vehicle direction, but the safety and ease of use decrease due to complex maneuvers

Engineering Contradiction:

Improvesteering safetyVSAvoidsteering operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical steering operations with an automated control system. The virtual vehicle's motion trajectory is automatically converted into steering angle commands by the execution controller, substituting complex manual mechanical maneuvers with automated electronic control that enhances safety while simplifying user interaction

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Extent of automation

If automatic steering control is implemented, then the operation simplicity increases, but the system complexity increases

Engineering Contradiction:

Improvesteering automation levelVSAvoidcontrol system complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The virtual vehicle serves multiple functions: it acts as a user interface for simplified input, a simulation environment for trajectory generation, and a translator that converts touch gestures into steering commands. This multi-functionality reduces the need for separate complex subsystems while achieving high automation

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A steering control method for a vehicle is provided. The method includes: displaying a first virtual vehicle on a display terminal; and when a motion trajectory of the first virtual vehicle is obtained, determining first steering information based on the motion trajectory, and sending the first steering information to an execution controller of the vehicle, where the execution controller is configured to control steering of the vehicle based on the first steering information.
