Solution Overview

Problem

Existing motorcycle control systems fail to effectively improve drivability by stabilizing the behavior of two-wheeled vehicles, which are more unstable and agile compared to four-wheeled automobiles, particularly during maneuvers like overtaking.

Innovation Solution

A controller that executes positional relationship adjustment operations, including adaptive cruise control and positional relationship approaching operations, to automatically adjust the motorcycle's speed and position relative to a preceding vehicle, while notifying the rider of the operation's status, enabling or disabling these operations based on road conditions and rider intent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If positional relationship approaching operation is enabled to assist overtaking, then overtaking assistance is improved, but motorcycle stability deteriorates

Engineering Contradiction:
Improveovertaking assistanceVSAvoidmotorcycle stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The system dynamically switches between enabling and disabling the positional relationship approaching operation based on real-time detection of rider intent through operation input devices. The control execution section monitors rider inputs and adjusts the automation level accordingly, allowing the system to transition between assisted overtaking mode and stable cruising mode as needed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The notification section provides continuous feedback to the rider about the execution state of the positional relationship approaching operation. This feedback mechanism keeps the rider informed about when the automated overtaking assistance is active, allowing the rider to maintain situational awareness and control despite the automated intervention

Inventive Principle:
Principle #23Feedback

2Ease of operation

If automated positional relationship adjustment is executed, then drivability is improved, but rider awareness of operation status deteriorates

Engineering Contradiction:
ImprovedrivabilityVSAvoidrider awareness
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The notification section executes notification operations that continuously inform the rider about the execution state of the positional relationship approaching operation. This feedback ensures the rider remains aware of when automated assistance is active, preventing information loss while maintaining improved drivability

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The notification section acts as an intermediary between the control execution section and the rider, translating the internal system state into comprehensible information for the rider. This intermediary function bridges the gap between automated control and rider awareness

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention obtains a controller and a control method capable of improving drivability of a motorcycle. In the controller and the control method according to the invention, an execution section of the controller executes positional relationship adjustment operation to control a positional relationship between a motorcycle and a preceding vehicle to a target positional relationship by automatically generating acceleration or deceleration to the motorcycle. During execution of the positional relationship adjustment operation, the execution section executes: first control operation for enabling and suspending execution of positional relationship approaching operation in which the positional relationship between the motorcycle and the preceding vehicle is controlled to be closer than the target positional relationship; and second control operation for executing the positional relationship approaching operation when determining that a rider of the motorcycle has an intention to overtake the preceding vehicle while the positional relationship approaching operation is suspended. During the execution of the positional relationship adjustment operation, the execution section executes notification operation for notifying the rider of information on the positional relationship approaching operation.
