Solution Overview

Problem

Existing vehicle thermal comfort control systems for ride-share vehicles fail to maintain consistent thermal comfort for occupants as they move around the cabin, leading to discomfort due to varying environmental conditions.

Innovation Solution

A method for controlling a thermal comfort control system in ride-share vehicles, which includes providing multiple occupant seats with seat comfort control systems that adjust thermal parameters, such as heating and ventilation, and a cabin comfort control system that adjusts the overall cabin temperature based on an average value of inputs from these seat systems, ensuring consistent comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single cabin temperature control system is used, then the system structure is simple, but occupants experience discomfort when moving between different zones with varying thermal environments

Engineering Contradiction:
Improvethermal comfort consistencyVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent divides the single cabin temperature control system into multiple zone-specific control systems. Each zone (e.g., driver seat, front passenger seat, rear seats) has its own temperature control mechanism and sensors, allowing independent temperature adjustment for different occupancy positions. This segmentation resolves the contradiction by maintaining thermal comfort consistency across zones while managing complexity through modular zone controllers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a multi-dimensional control approach by adding spatial dimensionality to temperature control. Instead of a single cabin-wide temperature setting, the system creates multiple temperature zones along the spatial dimension of the cabin, with each zone having its own setpoint and control parameters. This allows occupants to experience consistent comfort regardless of position while the system manages complexity through distributed zone controllers.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple zone control systems are implemented, then occupant comfort is improved in different cabin zones, but system complexity increases

Engineering Contradiction:
Improvezone-specific comfort adjustmentVSAvoidmulti-zone control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple zone control systems into a unified hierarchical control architecture. Individual zone controllers maintain independence for local adjustments, while a central controller coordinates across zones to achieve overall cabin comfort optimization. This merging approach enables zone-specific comfort adjustment while reducing perceived complexity through integrated control logic and shared communication protocols.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements universal control principles across all zones, where each zone controller performs the same basic functions (temperature sensing, setpoint management, actuator control) but adapts to zone-specific requirements. This multi-functionality approach allows the system to handle diverse zone needs while using standardized control components, thereby improving adaptability without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method for controlling a thermal comfort control system for ride share vehicles includes providing a plurality of occupant seats in a vehicle cabin and controlling a cabin set temperature using a cabin comfort control system configured to adjust a plurality of HVAC functions. At least one thermal comfort parameter is adjusted at a number of the plurality of occupant seats using at least one seat comfort control system. Adjusting the at least one thermal comfort parameter causes the cabin control module to adjust the set temperature of the vehicle cabin.
