Motorcycle Rider Assistance With Pitch-Corrected Environment Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rider-assistance systems for straddle-type vehicles are inadequate in detecting the peripheral environment when the riding or loaded state deviates from standard conditions, due to significant changes in pitch angle, which is not accounted for in their design.
Innovation Solution
A rider-assistance system that includes a peripheral environment detector, an input device, and a controller with an acquisition section to gather pitch angle correction target information and a correction operation section to adjust the detection accordingly, ensuring appropriate detection even in non-standard riding or loaded states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the peripheral environment detector is mounted to detect peripheral environment of the straddle-type vehicle, then the rider-assistance system can assist with driving operations, but the detection becomes inappropriate when the riding state or loaded state deviates from standard conditions due to significant pitch angle changes
Solution Approach 1:
The patent applies parameter changes by detecting the pitch angle of the vehicle body and using this parameter to correct the detection results from the peripheral environment detector. When the riding state or loaded state changes, the pitch angle changes accordingly, and the control unit adjusts the detection data based on this angle parameter to maintain accuracy across different operating conditions
Solution Approach 2:
The system implements feedback by continuously monitoring the pitch angle and using this information to dynamically adjust the peripheral environment detection. The control unit receives pitch angle information and feeds it back to correct the detection results, creating a closed-loop system that adapts to changing riding conditions
2Ease of operation
If the straddle-type vehicle has a short wheelbase and light body weight, then the vehicle is more maneuverable, but the pitch angle changes significantly when riding state or loaded state is not standard
Solution Approach 1:
The patent compensates for the significant pitch angle changes in lightweight, short-wheelbase vehicles by introducing pitch angle detection and correction parameters. The system detects the actual pitch angle caused by nonstandard loading or riding states and uses this parameter to adjust the peripheral environment detection, thereby maintaining measurement precision despite the vehicle's inherent sensitivity to loading conditions

AI summary
The present invention obtains a rider-assistance system capable of appropriately assisting with driving by a rider of a straddle-type vehicle and a control method for such a rider-assistance system.The rider-assistance system that assists with driving by the rider of the straddle-type vehicle includes: a peripheral environment detector that is mounted to the straddle-type vehicle and detects peripheral environment of the straddle-type vehicle; an input device that is mounted to the straddle-type vehicle and is operated by the rider of the straddle-type vehicle; and a controller that governs operation of the rider-assistance system. The controller includes: an acquisition section that acquires pitch angle correction target information that is target information on pitch angle correction of the peripheral environment detector; and a correction operation performing section that performs correction operation for detection of the peripheral environment by the peripheral environment detector on the basis of the pitch angle correction target information acquired by the acquisition section.
