Highway Convoy Speed Profiling for Resource-Efficient Vehicle Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating fuel efficiency in motor vehicles do not accurately account for the specific route portions traveled by the vehicle and cannot be used in a global fuel consumption control system with vehicles of different specifications, nor can they adjust driving modes to reduce energy consumption in a convoy setting.
Innovation Solution
A method for generating a resource-efficient track for a vehicle in operation, involving the CPU of a computer device, which determines a lead vehicle's track and adjusts the vehicle's speed profile to match or exceed the lead vehicle's efficiency, using data from sensors and environmental conditions to optimize energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a method evaluates fuel efficiency based on general driving data without specific route information, then the evaluation can be performed with available data, but the accuracy of fuel consumption estimation is reduced
Solution Approach 1:
The system pre-generates resource-efficient tracks for different route portions before the vehicle actually travels them. These tracks are stored and later used to evaluate actual fuel consumption by comparing with pre-calculated efficient paths, enabling accurate route-specific evaluation without requiring real-time data collection for each route segment
Solution Approach 2:
The route is divided into multiple portions or segments, and resource-efficient tracks are generated for each segment individually. This segmentation allows the system to account for specific characteristics of different route portions (such as terrain, traffic patterns, road conditions) to improve overall fuel consumption estimation accuracy
2Adaptability or versatility
If a method uses only vehicles with similar specifications and driving modes for fuel efficiency evaluation, then the evaluation is simplified, but the method cannot be used in a global fuel consumption control system comprising multiple vehicles with different specifications
Solution Approach 1:
The resource-efficient track generation method is designed to be universal and applicable to vehicles with different specifications. The system generates tracks based on route characteristics rather than vehicle-specific parameters, allowing the same track to be used by multiple vehicles regardless of their type, making the system compatible with global fuel consumption control networks
Solution Approach 2:
The system adjusts evaluation parameters based on vehicle characteristics. Different vehicle types can use the same resource-efficient tracks, but the fuel consumption evaluation is adjusted according to each vehicle's specific parameters (weight, engine type, aerodynamics), allowing accurate evaluation across diverse vehicle fleets without requiring separate systems for each vehicle type
3Ease of operation
If a method identifies operational problems requiring vehicle repairs, then maintenance needs are detected, but the method cannot be used to change the motor vehicle driving mode to reduce energy consumption on a given route portion
Solution Approach 1:
The system dynamically adjusts the driving mode and generates real-time control signals to the vehicle's motion control system based on the resource-efficient track evaluation. This allows the vehicle to change its operating characteristics (acceleration patterns, speed profiles, gear selection) during travel to minimize energy consumption on specific route portions, rather than just identifying maintenance needs
4Use of energy by moving object
If a method generates resource-efficient tracks for individual vehicles without considering lead vehicles, then the track generation is simpler, but the method cannot optimize energy consumption for vehicles moving in a convoy
Solution Approach 1:
The system merges the resource-efficient tracks of lead vehicles with those of following vehicles to create optimized convoy trajectories. By combining track information from multiple vehicles and considering their relative positions and speeds, the system generates coordinated paths that exploit drafting effects and reduce overall convoy energy consumption compared to individual vehicle optimization
