Electronic Controller Prioritizes Electric Brake Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-powered vehicle control systems do not effectively prioritize the actuation of electric brake devices over other components, leading to suboptimal control and potential inefficiencies in energy usage and braking performance.
Innovation Solution
A control device with an electronic controller that prioritizes the actuation of the electric brake device over other components, using conditions such as traveling environment, state, and battery level to manage power distribution and restrict actuation of other components when necessary, ensuring preferred operation of the electric brake device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric brake device and other components are supplied with electric power from a common battery without actuation priority, then all components can operate simultaneously, but the electric brake device cannot ensure preferred operation when power is limited
Solution Approach 1:
The control device preliminarily determines actuation priority of the electric brake device over other components before power distribution occurs. This preliminary prioritization ensures that when power limitations arise, the brake device is pre-positioned to receive power first, guaranteeing reliable brake operation while maintaining the ability to operate other components when power is available
2Reliability
If the electric brake device is given actuation priority over other components, then braking performance is improved, but other components may be restricted from operating when power is limited
Solution Approach 1:
The control device dynamically adjusts power distribution based on real-time conditions. When the electric brake device requires actuation, it receives priority power allocation. When braking is not required and power is available, other components can operate. This dynamic adjustment maintains brake reliability while maximizing overall system operability under varying power conditions
3Use of energy by moving object
If power is distributed without priority to all components, then energy usage is distributed evenly, but the electric brake device may not receive sufficient power when needed
Solution Approach 1:
The control device applies local quality by providing differentiated power distribution to different components based on their operational criticality. The electric brake device receives preferential power allocation when actuation is required, while other components receive power when available. This localized quality enhancement ensures the brake device gets sufficient power when needed while maintaining overall power distribution efficiency
