Vehicle With Distinctly Activated Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of controllers in vehicles, such as motorcycles and off-road vehicles, necessitates simultaneous activation in various scenarios to conserve battery power, leading to higher hardware costs and extended development cycles due to the requirement of network signal receiving and sending modules.
Innovation Solution
Implementing a dual-controller system where the first controller is activated via a local area network using a communications protocol, and the second controller is activated directly through hard-wired signals to its microprocessor, eliminating the need for additional communication hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all controllers are activated simultaneously using network management mechanisms, then diverse user requirements are met, but battery power is consumed excessively and hardware costs increase
Solution Approach 1:
The patent segments controller activation into two distinct groups: controllers activated via network management (first controllers) and controllers activated via direct hard-wired signals (second controllers). This segmentation allows selective activation based on scenario requirements, reducing unnecessary power consumption while maintaining the ability to activate all controllers when needed.
Solution Approach 2:
The patent implements periodic or conditional activation of controllers based on specific scenarios. Instead of continuous activation, controllers are activated only when their functions are required, with the second group of controllers being activated through direct signals only when needed, thereby reducing overall power consumption while maintaining adaptability.
2Adaptability or versatility
If network signal receiving and sending modules are added to each controller, then controllers can be activated selectively, but hardware costs and development cycles increase
Solution Approach 1:
The patent makes the first controllers multi-functional by equipping them with both network communication capabilities and direct signal reception capabilities. This allows a single controller to serve multiple activation methods, reducing the need for separate hardware structures while maintaining selective activation functionality.
Solution Approach 2:
The patent introduces a controller activation signal as an intermediary that can be transmitted through two different channels: network management signals for the first group of controllers and direct hard-wired signals for the second group. This intermediary signal mechanism enables selective activation without requiring every controller to have complex network communication hardware.
3Productivity
If network communication protocols are used for all controllers, then standardized communication is achieved, but development time and costs increase
Solution Approach 1:
The patent uses simple direct hard-wired signal connections for the second group of controllers, which are easier and faster to implement than full network communication protocols. While these connections are less versatile, they suffice for activation purposes, reducing development time and costs for controllers that only need basic activation functionality.
Solution Approach 2:
The patent applies network communication protocols partially - only to the extent needed for controller activation, rather than implementing full-featured communication protocols in all controllers. The second group of controllers receives only the essential activation signal through direct wiring, avoiding the overhead of complete protocol implementation and reducing development complexity.

AI summary
A vehicle includes a frame, a plurality of wheels supporting the frame, and a prime mover system and battery supported on the frame. The vehicle further includes at least one first controller communicating digitally using a communications protocol on a local area network, and a second controller. The first controller is capable of being activated out of a sleep state by an instruction transmitted by the local area network using the communications protocol, whereas the second controller is capable of being activated out of a sleep state by an activation signal transmitted by directly by hard wires without using the communications protocol.
