Solution Overview

Problem

Existing vehicle control systems face challenges in shifting control states to more advanced automation levels without ensuring a stable detection state, particularly when detecting information for control state transitions is unstable.

Innovation Solution

A vehicle control apparatus and method that utilize dual detection units with overlapping detection ranges, shifting control states based on a match degree threshold between object information detected by both units, ensuring a stable detection state for advanced automation levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the control state shifts to a more advanced automation level, then the vehicle control automation rate increases, but the detection stability deteriorates

Engineering Contradiction:
Improvevehicle control automation rateVSAvoiddetection stability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent combines multiple detection units (first detection unit and second detection unit) to perform redundant detection of the same peripheral objects. By merging their detection results and comparing match degrees, the system achieves more reliable and stable detection information, enabling safe transitions to higher automation levels where driver participation is reduced.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If single detection unit is used, then the device complexity is low, but the detection reliability is insufficient for advanced automation

Engineering Contradiction:
Improvedetection unit configurationVSAvoiddetection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies local quality by having different detection units specialize in different detection tasks or ranges, with overlapping fields of view. The first detection unit and second detection unit each have their own detection ranges that partially overlap, allowing them to complement each other's strengths and provide more reliable detection for critical areas.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system prepares for potential detection failures by implementing redundant detection beforehand. By having multiple detection units operating in parallel with overlapping ranges, the system creates a buffer against detection errors or failures, ensuring that reliable detection information is available even if one unit fails or provides inaccurate data.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A vehicle control apparatus comprises a first detection unit configured to have a first detection range, a second detection unit configured to have a second detection range which at least partially overlaps the first detection range, and a vehicle control unit configured to be capable of performing vehicle control based on a first control state and vehicle control based on a second control state which has a high vehicle control automation rate or a reduced degree of vehicle operation participation requested to a driver compared to the first control state. The vehicle control unit performs control to shift from the first control state to the second control state based on a condition that a match degree between pieces of preceding object information of a vehicle detected by the first detection unit and the second detection unit.
