Vehicle Driving Strategy Correction for Real-World Disturbances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving strategy methods for vehicles are based on idealized states and do not account for real-world driving conditions, leading to inefficiencies and customer dissatisfaction due to deviations from assumed maneuvers, such as headwind affecting coasting processes.
Innovation Solution
A method that compares the vehicle's movement with the driving strategy and corrects maneuver lines based on movement parameters like speed and distance, adjusting the strategy when predetermined conditions are met, using functions like linear, polygonal, or rational corrections to optimize energy efficiency.

Engineering Contradiction Analysis
1Use of energy by moving object
If a driving strategy based on idealized maneuver lines is used, then energy efficiency can be optimized theoretically, but the strategy fails to account for real-world disturbances such as headwind causing premature end of coasting processes
Solution Approach 1:
The system continuously compares actual vehicle movement with the planned driving strategy and uses this feedback to detect deviations caused by disturbance variables. When deviations are detected, the system corrects the maneuver lines and recalculates the driving strategy to maintain energy efficiency despite real-world conditions.
Solution Approach 2:
The driving strategy is made dynamic by allowing continuous correction of maneuver lines based on actual vehicle behavior. Instead of following fixed idealized paths, the system adapts the maneuver lines in real-time to match actual driving conditions, enabling the vehicle to respond flexibly to disturbances while maintaining optimization goals.
2Manufacturing precision
If fixed maneuver lines are specified for consumption optimization, then theoretical energy efficiency is achieved, but the system requires high precision in maintaining ideal states which is not achievable in practice
Solution Approach 1:
The system prepares for potential deviations by continuously monitoring actual movement against planned maneuver lines and having correction mechanisms ready. This proactive approach allows the system to compensate for disturbance variables before they cause significant deviations from the optimal path, maintaining both precision and robustness.
Solution Approach 2:
The system changes parameters of the maneuver lines (such as position, speed, timing) based on detected deviations from actual vehicle movement. By dynamically adjusting these parameters in response to real-world conditions, the system maintains high precision in achieving energy efficiency goals while remaining robust to operational variations.
3Device complexity
If the driving strategy does not account for actual vehicle movement deviations, then the system remains simple to implement, but energy efficiency is lost when disturbances cause premature end of maneuvers
Solution Approach 1:
The system implements a feedback mechanism that compares actual vehicle movement with the driving strategy and triggers corrections only when deviations are detected. This approach maintains relative simplicity by not requiring complex real-time control, while still improving energy efficiency through targeted adjustments to maneuver lines based on actual driving conditions.

AI summary
The invention relates to a method for changing a driving strategy (230) for a vehicle (200), wherein the driving strategy (230) is based on at least one manoeuvre line (220) of a plurality of manoeuvre lines (220), and wherein the manoeuvre lines (220) and the driving strategy (230) exhibit a dependence of a movement parameter as a function of a distance parameter. The method comprises comparing (S110) the driving strategy with a movement of the vehicle. It also comprises correcting (S130) at least one manoeuvre line of the plurality of manoeuvre lines based upon the comparison between the movement of the vehicle and the driving strategy and changing (S140) the driving strategy on the basis of the plurality of manoeuvre lines after correcting (S130) at least one of the manoeuvre lines of the plurality of manoeuvre lines if the movement of the vehicle and the driving strategy satisfy a predetermined condition. In this way, if appropriate, an improvement of a driving strategy with regard to real driving situations can be created.
