Hybrid Vehicle Charge Enforcement via Fuel Refill Lockout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hybrid vehicles with electric and internal combustion engines face inefficiencies in reducing emissions due to insufficient charging from external electrical grids, leading to increased reliance on the internal combustion engine and reduced electric driving capabilities.
Innovation Solution
An electronic control unit implements coercive measures to influence driver behavior by restricting fuel refilling or degrading vehicle performance if the battery is not sufficiently charged, ensuring optimal use of the electric drive.

Engineering Contradiction Analysis
1Object-generated harmful factors
If the driver refills fuel frequently without charging the battery, then the internal combustion engine can operate, but emissions increase and electric driving capability is reduced
Solution Approach 1:
The system applies preliminary anti-action by preventing fuel refilling before the harmful behavior (insufficient charging) occurs. The lockable fuel tank cover remains locked until the battery is sufficiently charged, proactively blocking the opportunity to refill fuel without charging, thereby preventing emissions increase before it happens.
Solution Approach 2:
The electronic control unit acts as an intermediary between the charging system and the fuel refilling system. It monitors battery charge status and controls the fuel tank cover locking mechanism, mediating between the electrical charging state and the mechanical fuel refilling capability to enforce the charging requirement.
2Object-generated harmful factors
If the fuel tank cover is locked to prevent refilling, then emissions are reduced by forcing electric drive use, but the driver loses operational freedom
Solution Approach 1:
The system applies dynamics by making the fuel tank cover locking state dynamic rather than fixed. The cover can transition between locked and unlocked states based on real-time battery charge status, allowing the system to adapt to changing conditions and provide driving mode flexibility when charging requirements are met while restricting it when they are not.
Solution Approach 2:
The system changes the parameter of fuel refilling accessibility based on the battery charge state parameter. When the battery charge state falls below the threshold, the fuel refilling parameter is changed to locked; when the threshold is met, it changes to unlocked, creating a conditional adaptability that balances emissions reduction with operational flexibility.
3Productivity
If the vehicle operates primarily on internal combustion engine, then immediate driving demand is met, but fuel consumption and emissions increase
Solution Approach 1:
The system implements feedback by continuously monitoring battery charge status and using this information to control fuel tank cover accessibility. The feedback loop ensures that the vehicle operates in electric mode when the battery is charged (reducing fuel consumption) while still allowing internal combustion engine operation when necessary, optimizing the balance between productivity and energy loss.

AI summary
A hybrid vehicle has an internal combustion engine drive that includes at least one internal combustion engine and an electromotive drive that includes at least one electric motor and a battery. The battery can be charged both via the internal combustion engine and via an external power supply. At least one electronic control unit is designed such that, in the event of at least one defined condition that indicates an insufficient use of the electromotive drive compared to the internal combustion engine drive, at least one coercive measure is taken to influence the behavior of the driver towards increasing the use of the electrical drive. The coercive measure may be keeping an automatically lockable fuel tank cover locked.
