Vehicle Command Confirmation System for Inconsistent Conditions

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Vehicles often receive unintended commands due to inconsistent vehicle conditions or accidental activations, leading to undesired actions such as opening a hatch when obstructed or locking doors while they are open, highlighting the need for a system to confirm intended commands.

Innovation Solution

A system comprising sensors and a processor that monitor vehicle conditions and alert the operator of inconsistent commands, allowing confirmation or cancellation of the command before execution, using communication devices like key fobs or smartphones for notification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the vehicle system actsuates immediately upon receiving a command, then the response speed is fast, but unintended actions occur due to inconsistent vehicle conditions

Engineering Contradiction:

Improvecommand response speedVSAvoidcommand execution reliability

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The system performs preliminary detection of vehicle conditions before executing the command. Sensors detect the current state of vehicle components (doors, hatches, transmission position) and the processor evaluates whether the command is consistent with these conditions before actuation occurs, preventing unintended actions while maintaining fast response when conditions are consistent

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by alerting the operator when a command is inconsistent with vehicle conditions. The communication device sends notifications to the key fob or smartphone, and the system waits for operator confirmation before actuation, ensuring reliability while allowing fast execution when no inconsistency exists

Inventive Principle:

Principle #23Feedback

2Reliability

If the system adds confirmation alerts for inconsistent commands, then command execution reliability improves, but the operation time increases

Engineering Contradiction:

Improvecommand execution reliabilityVSAvoidcommand execution time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial confirmation - it only requests operator confirmation when vehicle conditions are inconsistent with the command. When conditions are consistent, the system executes the command immediately without additional confirmation steps, thus maintaining high reliability for problematic commands while minimizing time loss for normal operations

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method and system are disclosed herein for confirming a potentially unintended command given to a vehicle. The method includes, but is not limited to, receiving a command from an operator configured to cause actuation of a vehicle system. The method further includes, but is not limited to, detecting a condition of the vehicle. The method further includes, but is not limited to, determining, with a processor, that the command is inconsistent with the condition. The method still further includes, but is not limited to alerting the operator that the command is inconsistent with the condition.
