Solution Overview

Problem

Traditional vehicle ignition systems require manual key turning and brake pedal depression, which can be cumbersome and lack safety features for accidental start prevention.

Innovation Solution

A system comprising sensors (pressure, RF, touch, cameras, etc.) and a processor that determines the presence of a driver, a corresponding key fob, and shifter input to automatically activate the ignition, enhancing user experience and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual key turning and brake pedal depression are required for ignition, then safety against accidental start is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvesafety against accidental startVSAvoidease of ignition activation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the manual mechanical ignition process (key turning and brake pedal depression) with an automated sensor-based system. Multiple sensors detect driver presence, key fob proximity, and shifter position to automatically activate ignition, eliminating the need for manual mechanical operations while maintaining safety through multiple verification conditions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If automated ignition based on sensor data is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of ignition activationVSAvoidcomplexity of ignition system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent divides the automated ignition system into distinct functional modules: driver presence detection sensors, key fob detection sensors, shifter position sensors, and a control unit that processes sensor data. This segmentation allows each component to perform a specific function, making the complex system more manageable and maintainable while providing seamless automated operation.

Inventive Principle:
Principle #1Segmentation

AI summary

Methods and systems are disclosed for activating a vehicle ignition system. An example vehicle includes an ignition system, a plurality of sensors, and a processor. The processor a processor is configured to determine, based on data received from the sensors, (i) that a person occupies a driver's seat of the vehicle, (ii) that a key fob corresponding to the vehicle is present, and (iii) that an input has been received at a shifter of the vehicle. The processor is also configured to responsively activate the ignition system.
