Motorcycle Rider Assistance Control for Group Stop and Crawl Behavior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rider-assistance systems for motorcycles face challenges in executing appropriate stopping or crawling behaviors during group travel due to the high degree of freedom in travel position and small body size, making it difficult for motorcycles to stop or crawl appropriately when traveling in a group.
Innovation Solution
A controller for a rider-assistance system that adjusts the positional relationship between a motorcycle and surrounding vehicles by executing first and second speed control operations based on surrounding environment information, determining the necessity to stop or crawl, and switching between automatic control operations to accommodate group travel modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional speed control operation is executed during group travel, then the motorcycle can maintain speed control, but it cannot stop or become a crawl with appropriate behavior due to high degree of freedom in travel position and small body size
Solution Approach 1:
The control device dynamically switches between first automatic control operation and second automatic control operation based on whether group travel is detected. This dynamic adaptation allows the system to provide appropriate stopping behavior for motorcycles in group travel scenarios, resolving the contradiction between maintaining reliability and adapting to group travel conditions.
Solution Approach 2:
The system changes control parameters and control strategies based on the group travel state. When group travel is detected, the control device executes second automatic control operation with parameters suitable for group travel, enabling appropriate stopping and crawling behavior while maintaining adaptability to the specific travel mode.
2Device complexity
If the motorcycle executes speed control operation similar to other vehicles, then the control logic can be simplified, but it cannot achieve appropriate stopping behavior due to small body size and high degree of freedom in travel position
Solution Approach 1:
The control device segments the speed control operation into two distinct modes: first automatic control operation for general scenarios and second automatic control operation for group travel scenarios. This segmentation allows the system to maintain simplified control logic within each mode while achieving appropriate stopping behavior through mode-specific control strategies.
Solution Approach 2:
The control device is designed with multi-functionality to handle both general speed control and group travel-specific speed control. By integrating both control operations into a single device that can switch between modes, the system avoids excessive complexity while ensuring appropriate stopping behavior for motorcycles in group travel.
3Reliability
If automatic control operation is executed to stop or crawl the motorcycle, then the stopping performance is improved, but the system must differentiate between group travel mode and non-group travel mode increasing control complexity
Solution Approach 1:
The control device dynamically determines whether group travel is present and switches between control operations accordingly. This dynamic mode differentiation improves stopping performance by applying appropriate control strategies while managing complexity through automated mode detection and switching logic.

AI summary
The invention obtains a controller and a control method capable of improving assistance performance for a rider. In a controller for a rider-assistance system, a speed control execution section executes first speed control operation to adjust a positional relationship between an own vehicle and another vehicle in a disabled state of a group travel mode, executes first automatic control operation to automatically stop the own vehicle or automatically make the own vehicle become a crawl during execution of the first speed control operation, executes second speed control operation to adjust the positional relationship between the own vehicle and another motorcycle in an enabled state of the group travel mode, executes second automatic control operation to automatically stop the own vehicle or automatically make the own vehicle become the crawl during execution of the second speed control operation, and changes behavior of the own vehicle between the first automatic control operation and the second automatic control operation.
