Straddle-Type Vehicle Rider Assistance Using Riding Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional controllers for straddle-type vehicles lack the ability to acquire information on objects other than the rider, making it difficult to execute appropriate assistance operations.
Innovation Solution
A controller equipped with an acquisition section that utilizes environment information detection systems, including sensors like ultrasonic, radar, and cameras, to gather information on surrounding objects, and an execution section that performs rider assistance operations based on this data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional controllers are used for straddle-type vehicles, then the control system is simple, but the controller cannot acquire information on objects other than the rider, making it difficult to execute appropriate assistance operations
Solution Approach 1:
The patent combines the environment information detection system (with sensors for detecting surrounding objects) and the riding object detection system into a single integrated controller. This merging allows the controller to acquire both surrounding environment information and riding object information, resolving the information loss problem while avoiding the need for completely separate control systems.
Solution Approach 2:
The controller is designed to perform multiple functions: it detects surrounding objects using environment sensors, detects riding objects using the same sensor system, and executes different types of assistance operations based on the detected information. This multi-functionality allows the single controller to handle various detection and control tasks without requiring multiple dedicated devices.
2Reliability
If the controller acquires information on surrounding objects using environment sensors, then the assistance operation accuracy is improved, but the device complexity increases
Solution Approach 1:
The environment information detection system is designed to serve multiple purposes: it detects surrounding objects for general safety monitoring and simultaneously detects riding objects by analyzing the same sensor data. This multi-functional design improves assistance operation accuracy without proportionally increasing detection system complexity.
Solution Approach 2:
The controller utilizes the environment sensor data for dual purposes: general surrounding object detection and specific riding object identification. The system serves itself by extracting multiple types of information from the same sensor inputs, reducing the need for additional dedicated sensors while maintaining high detection accuracy.

AI summary
The present invention obtains a controller and a control method capable of appropriately assisting with a rider. An acquisition section of a controller (20) for a straddle-type vehicle (100) acquires riding object information as information on a riding object as an object that is other than a rider (200) of the straddle-type vehicle (100) and rides on the straddle-type vehicle (100) on the basis of output of an environment information detection system (11) that includes at least one environment sensor (11a, 11b, 11c, 11d) that is mounted to the straddle-type vehicle (100), and detects information on a surrounding object as an object located around the straddle-type vehicle (100), and an execution section of the controller (20) executes assistance operation for the rider (200) of the straddle-type vehicle (100) on the basis of the riding object information.
