Adaptive Test Route Planning for Vehicle Load Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing transportation vehicle durability on defined circuits fail to ensure that vehicles are subjected to the intended loads, as they do not account for varying driver influences, weather conditions, and structural differences among vehicles, leading to inconsistent and inefficient testing.
Innovation Solution
A method that determines a test route in real-time by linking vehicle position data with road information and sensed loads, calculating a load characteristic value, and selecting the most utility-rich route to achieve a predefined load target value, thereby optimizing the application of loads on the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strictly defined test circuit is used, then the route layout and speed are standardized, but the actual loads applied to the vehicle cannot be ensured and driver fatigue increases
Solution Approach 1:
The test route is dynamically adapted during the test drive based on real-time monitoring of applied loads. The system continuously adjusts the route to ensure target loads are achieved while varying the driving pattern to reduce driver monotony and fatigue.
Solution Approach 2:
A feedback mechanism monitors the actual loads applied to the vehicle during testing and uses this information to adjust the test route in real-time, ensuring that the intended loads are consistently achieved while adapting to driver state and environmental conditions.
2Device complexity
If a fixed test circuit is used, then testing procedures are simplified, but varying driver influences and weather conditions cannot be accounted for
Solution Approach 1:
The test route transitions from a fixed predetermined path to a dynamic adaptive route that responds to real-time conditions including driver behavior patterns and weather changes, allowing the system to account for varying influences while maintaining structured testing.
Solution Approach 2:
The system changes route parameters dynamically based on monitored conditions, adjusting the test circuit characteristics in response to driver influences and environmental factors while maintaining the overall testing framework.
3Reliability
If loads are defined indirectly through route specification, then the test circuit can be standardized, but the intended loads cannot be ensured
Solution Approach 1:
The system implements direct load monitoring with feedback control, measuring actual loads applied to the vehicle and using this information to adjust the test route to ensure intended loads are achieved, eliminating the loss of direct load information.
Solution Approach 2:
The patent replaces indirect mechanical route-based load definition with direct sensor-based load measurement and electronic control, substituting the mechanical test circuit specification with an electronic feedback system that directly monitors and controls applied loads.

AI summary
A method, a device, and a computer program product wherein the further profile of a test route of a transportation vehicle is determined during a test run. Both the loads which are already applied to the transportation vehicle as well as the loads which act on the transportation vehicle on successive sections of road are included in the determination of the further test route. The test route is tailored individually to the transportation vehicle and to a load target value which is attained therewith. The satisfaction of the load target value is ensured in that the test route is adapted at any time in accordance with the actual applications of load and the loads which are expected.
