Solution Overview

Problem

Existing vehicle systems lack the ability to efficiently determine optimal wake-up times for occupants based on destination, object presence, and user preferences, leading to inefficient or inappropriate vehicle component actuation.

Innovation Solution

A vehicle computer system that determines a wake-up time for occupants by analyzing destination data, object classification, user input, and various factors such as sleep state, traffic conditions, and historical data to actuate vehicle components like displays and audio devices at appropriate times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the vehicle system actuates components based on simple fixed schedules, then the system complexity is low, but the user experience and timing accuracy are poor

Engineering Contradiction:
Improvewake-up time accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary detection of occupant presence and classification before determining the wake-up time. Sensors detect objects in the vehicle interior and classify them as occupants or non-occupants, then use this information along with destination data to calculate an optimal wake-up time that accounts for travel duration and preparation needs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors vehicle state, sensor data, and navigation information to dynamically adjust wake-up time predictions. It uses feedback from object detection sensors, destination updates, and travel condition changes to refine the wake-up time calculation and ensure accurate timing.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the system considers multiple factors (destination, objects, user preferences) to determine wake-up time, then the user experience is improved, but the computational complexity increases

Engineering Contradiction:
Improvepersonalization capabilityVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the wake-up time determination process into distinct functional modules: object detection sensors identify occupants, a classifier distinguishes occupants from non-occupants based on object characteristics, a navigation system provides destination data, and a calculator integrates these inputs with user preferences to compute the optimal wake-up time. This modular segmentation reduces processing complexity while maintaining comprehensive personalization.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If the system uses sensor detection to identify objects and classify them, then the accuracy of occupant identification is improved, but the time required for processing increases

Engineering Contradiction:
Improveoccupant identification accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The classifier performs partial classification by focusing on key distinguishing features of occupants versus non-occupants rather than analyzing all possible object characteristics. It uses sensor data to identify critical attributes (such as object position, size, and type) that sufficiently distinguish occupants from other objects, achieving accurate identification without exhaustive processing of all object properties.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A system comprises a computer having a processor and a memory. The memory stores instructions executable by the processor to determine a wakeup time for an occupant of a vehicle based on a destination and an object in an interior of the vehicle, and actuate a vehicle component to awaken the occupant.
