Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems fail to ensure continuous stable travel at high altitudes due to insufficient electric power management in hybrid vehicles.
Innovation Solution
A vehicle control system that includes an electric power generator, a battery, a motor, a traveling plan generator, and a plan modifier to increase electric power generation before high-altitude sections, adjusting the electric power generation plan to compensate for decreased power efficiency at higher elevations by modifying the electric power generation time or amount in preceding sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle travels to high-altitude sections using the original electric power generation plan, then the vehicle can reach the destination, but the electric power becomes insufficient and the vehicle cannot continue traveling stably
Solution Approach 1:
The plan modifier increases electric power generation in sections before the high-altitude section by modifying the electric power generation plan. This preliminary action accumulates sufficient electric power in advance to compensate for the power deficiency that will occur at high altitude, ensuring continuous stable travel.
2Use of energy by moving object
If the electric power generation plan is modified to increase power before high-altitude sections, then electric power sufficiency is improved, but the traveling time increases
Solution Approach 1:
The system performs preliminary electric power generation in sections before the high-altitude section, modifying the power generation plan to accumulate sufficient power in advance. This approach ensures that the vehicle has enough power for high-altitude travel without requiring time-consuming power generation during the critical high-altitude section.
Solution Approach 2:
The plan modifier changes the electric power generation parameters (amount and timing) by increasing power generation in sections before the high-altitude section. This parameter adjustment optimizes the balance between power sufficiency and traveling time by shifting power generation to periods when the vehicle is not constrained by altitude limitations.
3Loss of time
If the vehicle uses the original electric power generation plan without modification, then the traveling time is short, but the vehicle cannot ensure stable travel at high altitudes
Solution Approach 1:
The system modifies the electric power generation plan to perform preliminary power accumulation in sections before the high-altitude section. This ensures reliable stable travel at high altitude while minimizing the impact on overall traveling time by conducting power generation activities in advance rather than during the high-altitude section.
