Hybrid Vehicle Route Energy Allocation via Section Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility information processing systems for hybrid vehicles face challenges in allocating appropriate driving modes when the number of sections in a travel route exceeds the processing capacity of the vehicle's controller, leading to inefficient energy management and mode allocation.
Innovation Solution
The system employs a mobility information processing apparatus that merges sections with similar travel loads into fewer, larger sections, allowing for efficient allocation of EV and HV modes based on residual battery capacity and travel load, thereby optimizing energy usage and mode allocation even when the number of sections exceeds the controller's processing limit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the controller processes each section individually to allocate driving modes, then the allocation precision is improved, but the device complexity increases when the number of sections exceeds processing capacity
Solution Approach 1:
The patent merges multiple consecutive sections into a single integrated section when the total number of sections exceeds the controller's processing capacity. This merging approach maintains mode allocation precision by treating the combined section as a unified processing unit, while simultaneously reducing controller complexity by decreasing the number of individual sections that require separate processing. The merging strategy ensures that energy balance calculations and driving mode allocations remain accurate even for long travel routes with many small sections.
2Adaptability or versatility
If the number of sections is increased to cover the entire travel route, then the energy management coverage is improved, but the ease of operation deteriorates when exceeding controller limits
Solution Approach 1:
The patent implements a dynamic section management strategy where the system automatically adjusts the number and size of sections based on the controller's processing capacity. When the calculated number of sections exceeds the controller's limit, the system dynamically merges sections to reduce the total count while ensuring complete coverage of the travel route. This dynamic adaptation maintains comprehensive energy management coverage for the entire route while keeping the operational complexity within acceptable limits for the controller.
3Device complexity
If sections are merged to reduce processing load, then the device complexity is reduced, but the measurement precision of energy balance calculation may deteriorate
Solution Approach 1:
The patent performs energy balance calculations on the merged section as a unified unit, aggregating the travel loads of all individual sections within the merged section. This approach maintains measurement precision by calculating the total energy balance for the entire merged section rather than approximating individual section balances. The system determines the appropriate driving mode for the merged section based on the aggregated energy requirements, ensuring accurate energy management even though multiple individual sections have been combined into a single processing unit.

AI summary
A mobility information processing apparatus includes: an allocator that allocates one driving mode-selected from driving modes having different drive forms to each partitioned section, in a route of a moving object; and an estimator that estimates the driving mode selected for each section located apart from a predetermined point in the route and that calculates an estimated amount of energy required for traveling in the section estimated to correspond to the one selected driving mode among the driving modes, wherein the allocator determines whether the one selected driving mode is allocated to each section up to a predetermined point in the route on the basis of an allocated energy amount obtained by subtracting the estimated energy amount calculated by the estimator from a residual energy amount of a power source used in the one selected driving mode for each section up to the predetermined point in the route.
