Straddle-Type Vehicle Control for Group Travel Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional controllers for straddle-type vehicles struggle to execute appropriate positional relationship adjustment operations when multiple vehicles travel in unique formations, such as side by side or in lines, due to their smaller body size, which affects rider assistance performance.
Innovation Solution
A controller that switches between first and second operation modes based on the validity of a group travel mode, adjusting travel speed to manage positional relationships with other vehicles, using sensors and notification devices to enhance rider assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional controller executes positional relationship adjustment operation, then the travel speed is automatically changed based on positional relationship information, but it cannot execute appropriate adjustment when multiple straddle-type vehicles travel in unique formations due to their small body size
Solution Approach 1:
The controller dynamically switches between first and second operation modes based on whether group travel mode is valid. This dynamic adaptation allows the system to adjust its behavior according to the travel situation, improving reliability in group travel scenarios while maintaining conventional performance in normal situations.
Solution Approach 2:
The system changes the operational parameters of the positional relationship adjustment based on the group travel mode status. When group travel mode is valid, the controller applies different speed adjustment logic and target selection criteria, effectively adapting to the unique formations of multiple straddle-type vehicles.
2Adaptability or versatility
If the controller switches between first and second operation modes based on group travel mode validity, then appropriate positional adjustments can be executed in various travel scenarios, but the control system becomes more complex
Solution Approach 1:
The control logic is segmented into distinct first and second operation modes, each handling specific travel scenarios. This segmentation allows the complex adaptation requirements to be divided into manageable, well-defined control routines, making the system easier to implement and maintain despite the increased functionality.
Solution Approach 2:
The controller preliminarily determines whether group travel mode is valid before executing positional relationship adjustment. This preliminary assessment allows the system to pre-select the appropriate operation mode, simplifying the decision-making process during actual adjustment execution and reducing overall control complexity.

AI summary
The invention obtains a controller and a control method capable of improving assistance performance for a rider. A controller for behavior of a straddle-type vehicle (100) includes: an acquisition section that acquires positional relationship information between the traveling straddle-type vehicle (100) and a target (200); and an execution section that executes positional relationship adjustment operation to automatically change a travel speed of the straddle-type vehicle (100) on the basis of the positional relationship information acquired by the acquisition section and to thereby adjust a positional relationship between the straddle-type vehicle (100) and the target (200). In the positional relationship adjustment operation, the execution section switches between a first operation mode in which the positional relationship between the straddle-type vehicle (100) and the target (200) is brought into a first state and a second operation mode in which the positional relationship between the straddle-type vehicle (100) and the target (200) is brought into a second state according to whether a group travel mode is valid.
