Vehicle Control System Slipping-by Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face issues with erroneous determination of a preceding vehicle's start, leading to premature start of the host vehicle, especially when a slipping-by vehicle is misinterpreted as the preceding vehicle, which can result in incorrect start signals.
Innovation Solution
A vehicle control system that includes an electronic control unit configured to recognize the vehicle speed and surrounding environment, determining if the host and preceding vehicles are stationary, and using conditions to verify the start of adjacent vehicles before initiating the host vehicle's start, employing radar sensors and cameras for accurate object recognition and differentiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If detection wave or camera information is used to determine preceding vehicle start, then the host vehicle can automatically start when the preceding vehicle starts, but erroneous detection occurs when a slipping-by vehicle approaches the preceding vehicle
Solution Approach 1:
The detection system is segmented into multiple independent detection units: radar sensors for detecting the preceding vehicle, adjacent vehicle, and slipping-by vehicle separately. Each vehicle type is detected and tracked independently, allowing the system to distinguish between a slipping-by vehicle approaching the preceding vehicle and the preceding vehicle actually starting, thus resolving the erroneous detection problem while maintaining automatic start functionality
Solution Approach 2:
The patent introduces an intermediary verification mechanism that cross-checks detection data from multiple sources (radar sensors, cameras) and multiple detection targets (preceding vehicle, adjacent vehicle, slipping-by vehicle). This intermediary verification layer filters out false positives caused by slipping-by vehicles before triggering the automatic start function, ensuring reliable detection while preserving automation
2Productivity
If the host vehicle starts immediately when the preceding vehicle is detected to have started, then the automatic start function is achieved, but the host vehicle may start erroneously due to misinterpretation of a slipping-by vehicle
Solution Approach 1:
The system performs preliminary detection and verification actions before triggering the automatic start. Radar sensors continuously monitor and distinguish between slipping-by vehicles and preceding vehicle start events in advance. This preliminary verification ensures that the automatic start function only activates when truly necessary, maintaining fast response for legitimate cases while preventing erroneous starts
Solution Approach 2:
The patent implements a feedback mechanism where detection results are continuously verified against multiple criteria (vehicle position, movement pattern, detection consistency). The system provides feedback loops that confirm whether a detected movement is indeed a preceding vehicle start or a slipping-by vehicle event, ensuring accurate start triggering while maintaining rapid response capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents the host vehicle from starting erroneously due to misinterpretation of a slipping-by vehicle as the preceding vehicle, ensuring accurate detection and delayed start until adjacent vehicles are confirmed to have started, thereby enhancing safety and reliability.
Implementation Method 1
the radar sensor transmits an electromagnetic wave to the surrounding environment and, based on a reception result of the electromagnetic wave, determines a start status of the preceding vehicle

AI summary
A vehicle control system includes an actuator and an electronic control unit. The electronic control unit is configured to determine one of the following conditions is satisfied: (i) an adjacent vehicle has started; (ii) a first timing at which the preceding vehicle has started does not indicate a second timing at which a slipping-by vehicle has been lost; and (iii) a second preceding vehicle has started. The electronic control unit is configured to start the host vehicle by using the actuator when at least one of the conditions is satisfied.
