Solution Overview

Problem

Existing technologies struggle to support motorcycle riders effectively during automatic decelerating operations, especially when approaching obstacles, due to the unique characteristics of motorcycle travel, such as narrower vehicle width and greater freedom in lane position.

Innovation Solution

A control system that acquires relative position information of lane boundaries and adjusts the detection angle range of a forward environment detecting device based on this information, allowing for a wider detection range when the motorcycle is positioned closer to the lane boundary, thereby enhancing collision avoidance capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the detection angle range is fixed for all traveling positions, then the device complexity is reduced, but the reliability of obstacle detection deteriorates when the motorcycle travels near lane boundaries

Engineering Contradiction:
Improveobstacle detection reliabilityVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The detection angle range is made dynamically adjustable based on the motorcycle's traveling position. When the motorcycle is detected to be near a lane boundary, the detection angle range is automatically widened to cover the adjacent lane, ensuring reliable obstacle detection in lane splitting scenarios without requiring multiple fixed detection systems

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The detection angle range parameter is changed according to the motorcycle's position relative to lane boundaries. The system adjusts this parameter dynamically - using a narrower angle when centered in the lane and a wider angle when near lane boundaries, optimizing detection reliability for different traveling conditions

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the detection angle range is widened to cover lane splitting scenarios, then the obstacle detection capability is improved, but the device complexity increases

Engineering Contradiction:
Improvedetection adaptability to lane splittingVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Rather than providing separate detection systems for different scenarios, the patent implements a dynamic detection angle adjustment mechanism that adapts to lane splitting situations in real-time based on motorcycle position and lane boundary detection, achieving versatility without proportional complexity increase

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The forward environment detecting device serves multiple functions through dynamic angle adjustment - it can detect obstacles in normal traveling positions with a narrower angle and automatically widen to detect obstacles in adjacent lanes during lane splitting, making a single device versatile for multiple traveling scenarios

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If automatic decelerating operation is implemented for motorcycles, then the driver support capability is improved, but the ease of operation deteriorates due to the need for specialized control logic

Engineering Contradiction:
Improvedriver support capabilityVSAvoidcontrol logic complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The automatic decelerating operation control logic dynamically adjusts detection parameters based on motorcycle traveling position. When lane splitting is detected, the system automatically widens the detection angle and adjusts deceleration control accordingly, providing specialized support without requiring separate control systems for different scenarios

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention provides a control system and a control method capable of appropriately supporting driving of a motorcycle by a rider. The control system includes an execution unit that causes the motorcycle to execute an automatic decelerating operation in a case where an obstacle is located in a predetermined range where a collision avoiding operation of the motorcycle is required, a lane position information acquiring unit that acquires relative position information of a lane boundary with respect to the motorcycle during traveling, and a detection angle range setting unit that set a detection angle range of a forward environment detecting device to be wide in a case where a determination reference is satisfied, in which the determination reference includes a condition that the lane position information acquired by the lane position information acquiring unit satisfies a prescribed condition.
