Vehicle Idling Controller Slope Detection Engine Stop Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle engine control systems, such as ISG apparatus, fail to prevent engine stoppage when a vehicle is parked on an inclined surface, leading to potential accidents due to unintended vehicle movement.
Innovation Solution
An apparatus and method utilizing height information management units and idling controllers to determine vehicle slope and control engine idling, without requiring additional hardware, by comparing slope information with reference values and adjusting engine operation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the ISG apparatus automatically idle-stops the engine to save energy and reduce carbon dioxide discharge, then fuel efficiency is improved, but the engine cannot stop when parked on an inclined surface leading to vehicle movement and safety hazards
Solution Approach 1:
The system performs preliminary detection of slope information using existing height information management units (GPS, altimeters, barometers) before the engine idle-stop decision is made. By anticipating the slope condition in advance, the system can determine whether the vehicle is on an inclined surface and prevent engine stoppage accordingly, thus maintaining safety without sacrificing fuel efficiency on level ground
Solution Approach 2:
The system continuously monitors height information and slope conditions, using this feedback to dynamically adjust the engine idle-stop control decisions. When the detected slope exceeds a predetermined threshold, the system receives feedback to maintain engine operation, creating a closed-loop control that balances fuel efficiency and safety based on real-time conditions
2Reliability
If a separate apparatus is added to determine geographical characteristics and prevent engine stoppage on slopes, then vehicle safety is improved, but device complexity and cost increase
Solution Approach 1:
The system makes existing multi-functional components (height information management units originally designed for navigation and positioning) serve an additional function of slope detection for engine control. By reusing existing hardware resources for dual purposes, the system achieves safety improvement without adding dedicated separate apparatus, thus reducing device complexity and cost
Solution Approach 2:
The existing height information management units and navigation systems perform self-service by providing slope detection capability as part of their normal operation. The system leverages the inherent capabilities of existing components to determine geographical characteristics and control engine operation, eliminating the need for separate dedicated detection apparatus

AI summary
Disclosed is an apparatus for controlling engine using height information capable of preventing an engine from stopping according to a position of a vehicle. An apparatus for controlling an engine of a vehicle using height information includes: a height information management unit storing a plurality of height information; and an idling controller that extracts one or more height information according to a position of the vehicle from the height information management unit to determine a slope of the vehicle and controls the idling of the vehicle according to the determination result.
