Solution Overview

Problem

Existing advanced driver-assistance systems (ADAS) face challenges in effectively mitigating the effects of collisions by determining optimal responses based on seat occupancy and obstacle conditions, particularly when limitations in stopping distance and steering maneuvers are present.

Innovation Solution

A system and method that includes a processor and memory to determine seat occupancy and evaluate candidate responses, such as emergency braking and steering maneuvers, to mitigate collision effects by considering seat occupancy and obstacle conditions, thereby optimizing collision avoidance strategies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vehicle implements a steering maneuver to avoid collision, then the collision avoidance effectiveness is improved, but the vehicle may collide with other obstacles or objects on the opposite side

Engineering Contradiction:
Improvecollision avoidance effectivenessVSAvoidcollision with other obstacles
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of seat occupancy status before executing collision avoidance maneuvers. By determining in advance whether the opposite seat is occupied, the system can pre-select appropriate avoidance strategies, preventing harmful collisions with other obstacles when passengers are present

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors seat occupancy status and uses this feedback information to dynamically adjust collision avoidance decisions. The occupancy detection module provides real-time feedback that influences the selection of avoidance maneuvers, ensuring the vehicle does not steer into areas where passengers are located

Inventive Principle:
Principle #23Feedback

2Reliability

If the vehicle applies emergency braking to avoid collision, then the collision mitigation effectiveness is improved, but the stopping distance requirement increases

Engineering Contradiction:
Improvecollision mitigation effectivenessVSAvoidstopping distance
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The system dynamically selects between different avoidance strategies (steering maneuvers vs. emergency braking) based on real-time conditions including seat occupancy status. This dynamic decision-making allows the system to choose the most effective maneuver while considering the vehicle's stopping distance capabilities and the occupied seats' positions

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If the system tailors collision responses to seat occupancy status, then the injury severity reduction is improved, but the system complexity increases

Engineering Contradiction:
Improveinjury severityVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system divides the vehicle interior into distinct occupied and unoccupied zones by detecting seat occupancy status. This segmentation allows the collision avoidance system to tailor maneuvers specifically protecting occupied areas, reducing injury severity through targeted protection strategies

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The seat occupancy detection module serves multiple functions: it identifies passenger locations for protection, determines appropriate avoidance maneuvers, and prevents harmful steering into occupied areas. This multi-functionality reduces overall system complexity by combining several protective functions into a single detection system

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

AI summary

A system for mitigating an effect of a collision between a vehicle and an obstacle can include a processor and a memory. The memory can store a seat occupancy determination module and a set of modules including a candidate response determination module, a candidate response evaluation module, and a controller module. The seat occupancy determination module can determine a state of a seat with respect to being occupied by a living being, the seat being on a first side opposite of a second side at which an operator is located. The set of modules can cause, in response to the state being: (1) occupied, a first set of operations to be implemented and (2) unoccupied, a second set of operations to be implemented. Each of the first set and the second set can be different from a current trajectory of the vehicle and can mitigate the effect of the collision.
