Agricultural Vehicle Control Unit Energy Check Before Application Run
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for monitoring the energy storage system in agricultural vehicles are complex and require battery sensors, which are expensive, and do not accurately predict the state of the battery, leading to potential power supply failures during applications.
Innovation Solution
A computer-implemented method assesses the feasibility of applications on a control unit by comparing required energy parameters with available energy parameters from the storage device, preventing or allowing the application to run based on this comparison, without the need for a battery sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a battery sensor is used to monitor the energy storage system's condition, then the measurement precision of battery state is improved, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the essential measurement function from a dedicated battery sensor and implements it through existing control unit components that can calculate battery state parameters (voltage, current, temperature, state of charge) through mathematical processing of electrical signals already present in the system, eliminating the need for additional expensive sensors
Solution Approach 2:
The patent replaces the physical battery sensor hardware with a computational approach using the control unit's processor to calculate battery state parameters from electrical measurements, substituting a mechanical/sensor-based system with an electronic/computational system that achieves the same measurement precision without additional hardware complexity
2Productivity
If the control unit runs an application without sufficient energy assessment, then the productivity is improved, but the reliability of power supply deteriorates
Solution Approach 1:
The patent performs preliminary assessment of the energy storage system's capacity and state of charge before allowing application execution on the control unit, calculating whether sufficient energy is available to complete the application without interruption, thereby ensuring power supply reliability while maintaining productivity
Solution Approach 2:
The patent implements a feedback mechanism where the control unit continuously monitors the battery state parameters during application execution and can interrupt or terminate the application if the energy level drops below a threshold, ensuring that power supply reliability is maintained while allowing productive operation within safe limits
