Vehicle Control System Switch Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of driving modes in vehicles requires a large number of switches, making operation difficult, especially on motorcycles, due to the need for multiple exclusive switches which occupy space and complicate handling.
Innovation Solution
A control system with a selecting switch for choosing driving modes and forward and reverse sequence regulating switches to change controlled steps in a predetermined order, allowing shared use of regulating switches among modes, reducing the number of components and improving operational ease by maintaining final steps when signals are continuously inputted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If exclusive switches are provided for each driving mode to enable independent control, then the ability to regulate each driving mode is improved, but the number of switches increases and the switches arranging space becomes large
Solution Approach 1:
The patent applies universality by making a single switch mechanism serve multiple driving modes. Instead of providing exclusive switches for each driving mode (engine output mode, traction control performance mode, limiting speed mode, ABS mode, electronic suspension mode, windshield mode), one switch is designed to regulate all these modes sequentially or selectively, reducing the total number of switches while maintaining full regulatory capability across all modes
2Adaptability or versatility
If exclusive switches are provided for each driving mode, then the regulation capability for each mode is improved, but the switches must be arranged away from the grip making operation during driving difficult
Solution Approach 1:
By consolidating multiple driving mode regulations into a single switch, the patent enables all driving modes to be controlled from one location that can be positioned within easy reach of the driver's grip. This eliminates the need to arrange multiple switches away from the grip area, significantly improving ease of operation during driving while maintaining full regulatory capability
3Adaptability or versatility
If multiple exclusive switches are provided, then each driving mode can be controlled independently, but it takes time for the rider to look for the switch in the driving mode to be regulated
Solution Approach 1:
The single multi-functional switch eliminates the need for riders to search through multiple switches to find the correct one for each driving mode. All modes are regulated through one switch, reducing the time to locate the correct control to nearly zero while maintaining independent regulation capability for each mode through sequential or selective operation

AI summary
A controller system for vehicle which has a plurality of driving modes which influence driving feeling, and performs selection from the driving modes and the regulation by inputs from a selecting switch, a forward sequence regulating switch, and a reverse sequence regulating switch. For each input from the selecting switch, changing to the driving mode according to a predetermined normal order. For each input from each of the regulating switches, the current controlled step is changed in a predetermined tendency direction. In a state where the controlled step reaches a final step, the state of the final step is maintained even when the same regulating signal is inputted.
