Vehicle Control Apparatus Predicts Risk Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to accurately inform drivers of potential safety function failures due to insufficient battery energy and do not adequately manage load restrictions to prevent power shortages in safety systems, especially in risky driving areas, leading to potential safety hazards.
Innovation Solution
A vehicle control apparatus that predicts risk areas and calculates the required battery power, notifying the driver of potential safety function failures and implementing load restrictions to ensure safety system functionality by managing battery charging and discharging based on environmental and driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the driver is informed of battery energy reduction as it actually occurs, then the driver receives timely information, but the information may be too late to prevent safety function failures
Solution Approach 1:
The system performs preliminary assessment of battery energy sufficiency by calculating expected energy consumption for safety functions based on detected driving conditions (weather, road, traffic) before the actual energy depletion occurs. This allows advance notification to the driver, enabling them to take preventive actions such as seeking alternative routes or reducing non-essential electrical load before safety functions fail.
Solution Approach 2:
The system applies preliminary anti-action by predicting potential safety function failures based on current battery energy levels and expected consumption patterns. When insufficiency is predicted, the system issues warnings and can proactively manage electrical loads to prevent the harmful event (safety function failure) from occurring in the first place.
2Reliability
If the vehicle uses more electrical energy to operate safety functions in risky areas, then safety system performance is improved, but battery energy depletes faster
Solution Approach 1:
The system dynamically adjusts electrical energy allocation based on real-time driving conditions and battery energy levels. When approaching risky areas and battery energy is sufficient, the system increases power allocation to safety functions. When battery energy is low, the system reduces or prioritizes only critical safety functions, creating a dynamic balance between safety performance and energy conservation.
Solution Approach 2:
The system changes operational parameters of electrical equipment based on battery energy status and environmental conditions. It adjusts the power consumption levels of safety functions, climate control, and entertainment systems to match available battery energy while maintaining adequate safety system operation during risky driving conditions.
3Use of energy by moving object
If the vehicle restricts feeding to electrical equipment to conserve battery energy, then battery energy is preserved, but safety functions may not operate properly
Solution Approach 1:
The system applies local quality by differentiating between critical and non-critical electrical equipment. Critical safety functions (brakes, steering, airbags) receive prioritized power allocation and are protected from load restrictions, while non-critical equipment (climate control, entertainment, comfort features) are subject to feeding restrictions. This ensures safety functions operate properly while conserving battery energy through selective load management.
