Hybrid Powertrain Control for Residual Value Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The residual value of hybrid vehicles is unevenly distributed among components like the internal combustion drive system, electric drive system, and clutch, leading to assessment based on the lowest component's value, affecting overall vehicle value.
Innovation Solution
A hybrid vehicle with a controller that performs driving mode, operating point, and clutch control to balance the residual values of these systems by adjusting power output and engagement conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the hybrid vehicle operates with two drive sources (engine and motor) to provide optimal output and torque, then the driving performance is improved, but the residual value becomes unevenly distributed among components
Solution Approach 1:
The patent implements dynamic control of drive mode selection and power distribution based on real-time monitoring of component residual values. The controller adjusts the operating modes (EV mode, HEV mode, series mode) and power output ratios between engine and motor according to the residual value status, making the system adaptable to changing component conditions rather than using fixed operating parameters
Solution Approach 2:
The patent changes operational parameters including drive mode selection, power output conditions, and clutch engagement states based on residual value differences. When the residual value difference between engine and motor exceeds a preset range, the system modifies parameters such as reducing motor power output or adjusting clutch engagement frequency to prevent further degradation of the lower-valued component
2Reliability
If the residual value of one component is excessively low compared with other major components, then the overall residual value is assessed based on the lowest component, but continuing to use that component accelerates its degradation
Solution Approach 1:
The system performs preliminary protective actions by detecting residual value differences before they lead to severe component degradation. When the residual value difference exceeds the preset range, the controller proactively adjusts operating parameters to prevent further deterioration of the lower-valued component, rather than waiting for failure or significant damage to occur
Solution Approach 2:
The system uses its own operational data and residual value monitoring capabilities to automatically adjust its operation. The controller continuously monitors component states and self-adjusts power distribution and drive mode selection without external intervention, allowing the vehicle to preserve its own residual value through intelligent autonomous control

AI summary
The hybrid vehicle includes a drive system including an internal combustion drive system and an electric drive system, a clutch that selectively connects the internal combustion drive system and the electric drive system, and a controller that performs at least one of driving mode control, operating point control, or clutch control, when entering residual value preservation control for balancing respective residual values of the internal combustion drive system, the electric drive system, and the clutch.
