Motorcycle Control Device for Public Road Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automotive vehicles designed for both public and non-public roads incur significant costs and reduced convenience due to the need for separate configurations, as existing systems do not efficiently allow switching between public and non-public road modes without relying on antilock brake systems on non-public roads.
Innovation Solution
A control device that detects the removal of public road equipment and determines presence on a non-public road area, enabling a selectable non-public road mode where the antilock brake system can be disabled, using a removal detecting unit, determining unit, and drive control unit, along with a non-public road area detecting unit, to change the vehicle's settings without special operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automotive vehicle is equipped with antilock brake system and public road equipment, then the vehicle can safely operate on public roads, but the cost increases and the vehicle becomes less suitable for non-public road use
Solution Approach 1:
The vehicle system dynamically switches between public road mode and non-public road mode based on detected conditions. The control device changes operational parameters of the antilock brake system and other equipment depending on whether public road equipment is detected, allowing the same physical hardware to adapt its behavior to different operational contexts without requiring separate vehicle configurations
Solution Approach 2:
The system changes operational parameters of existing equipment based on mode detection. When non-public road mode is detected (through removal detecting unit detecting absent public road equipment), the control device modifies parameters such as disabling antilock brake system intervention or changing display configurations, transforming the vehicle's operational characteristics without adding or removing physical components
2Adaptability or versatility
If the automotive vehicle is remodeled to run on both public and non-public roads, then versatility improves, but convenience deteriorates due to special operation requirements
Solution Approach 1:
The vehicle system automatically detects whether it is operating on public or non-public roads through removal detecting units that monitor the presence or absence of public road equipment. The determining unit autonomously decides the operational mode based on these detections, and the control device automatically adjusts system parameters without requiring driver intervention or special operations, making the versatility transition seamless and convenient
Solution Approach 2:
The system employs continuous feedback through removal detecting units that monitor equipment presence, feeding this information to the determining unit which then adjusts operational modes. This closed-loop feedback mechanism ensures the vehicle automatically adapts to the appropriate mode based on real-time detection of public road equipment status, eliminating the need for manual mode selection
3Productivity
If the antilock brake system is disabled on non-public roads, then performance for non-public road use improves, but safety on public roads may be compromised
Solution Approach 1:
The antilock brake system operates dynamically with different control parameters depending on the detected mode. On public roads, the system functions with full safety interventions. When non-public road conditions are detected (through absence of public road equipment), the control device changes operational parameters to disable or suppress antilock brake system interventions, allowing optimized performance for non-public road use while maintaining the capability for safety-critical operation when needed

AI summary
A control device (69) for a motorcycle includes a removal detecting unit (66) for detecting the removal of an equipment, which is required during a public road running of the automotive vehicle, from the motorcycle, a determining unit (64) for determining the presence of the motorcycle on a non-public road area in the event that a determining condition (65) including a detection signal fed from the removal detecting unit (66) is satisfied, and a drive control unit (57) operable in response to a determining signal from the determining unit (64) to set a non-public road mode appropriate to the non-public road running. The equipment referred to above is at least one of a back viewing mirror (30), a headlight (28), a tail lamp (34), a number plate (42), a license lamp (44), a warning horn, a side stand (19) and turn indicators (32, 38).
