Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for preventing jackrabbit accidents in vehicles are inadequate as they do not effectively consider errors in control devices and lack evidence for determining the jackrabbit state, leading to suboptimal control and reliability issues.
Innovation Solution
A vehicle black box apparatus that synchronizes accelerator position signals, throttle position signals, and photographed image signals to determine the jackrabbit state and automatically shuts off the fuel pump power, providing analysis information for investigating causes and preventing accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing jackrabbit prevention technologies are used, then the vehicle can detect jackrabbit state, but the control is suboptimal due to not considering control device errors and lack of reliable evidence
Solution Approach 1:
The patent introduces a black box as an intermediary device that independently acquires and stores accelerator position signals, throttle position signals, and photographed image signals. This black box serves as a mediator between the control devices and the determination system, providing reliable evidence without being affected by control device errors. The black box stores these signals synchronously with vertical synchronization signals, creating an independent evidence chain that resolves the contradiction between reliability and measurement precision.
Solution Approach 2:
The system implements feedback by continuously monitoring and comparing accelerator position signals with throttle position signals, and verifying them against photographed image signals stored in the black box. When discrepancies are detected between these independent signal sources, the system can identify potential control device errors and adjust the jackrabbit state determination accordingly, improving both reliability and measurement precision through iterative verification.
2Measurement precision
If multiple signals are synchronized and stored for analysis, then the jackrabbit state can be determined more accurately, but the device complexity increases
Solution Approach 1:
The black box is designed as a multi-functional device that simultaneously performs multiple tasks: acquiring accelerator position signals, acquiring throttle position signals, capturing photographed images, synchronizing all these signals with vertical synchronization signals, and storing them for later analysis. By consolidating these functions into a single universal device, the patent reduces overall system complexity while maintaining high measurement precision for jackrabbit state detection.
3Object-affected harmful factors
If the fuel pump power is shut off automatically upon jackrabbit detection, then accident prevention is improved, but the ease of operation decreases due to automatic intervention
Solution Approach 1:
The system applies preliminary anti-action by automatically shutting off fuel pump power when jackrabbit state is detected, preventing the harmful effect of uncontrolled vehicle movement before it can cause an accident. This automatic intervention occurs rapidly based on synchronized signal analysis from the black box, stopping the jackrabbit condition at its source by cutting fuel supply to the engine, thereby prioritizing safety over driver control autonomy in critical situations.

AI summary
An apparatus for preventing a jackrabbit accident using a vehicle black box includes a jackrabbit accident prevention unit that is provided in the vehicle black box, synchronizes an accelerator position signal with a vertical synchronization signal for recording of an image to generate first jackrabbit analysis information to be transmitted to an accident record unit, combines the accelerator position signal with a throttle position signal to be transmitted to the accident record unit as second jackrabbit analysis information and to determine jackrabbit based on the second jackrabbit analysis information, and prevents the jackrabbit accident by automatically shutting off driving power to a fuel pump in the jackrabbit state, and the accident recording unit that provides horizontal and vertical synchronization signals for storing of an image to the jackrabbit accident prevention unit, maps the first jackrabbit analysis information with a recorded image, and stores the mapping result in a memory card.
