Rider Assistance Sensor Pitch Correction for Variable Load States
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 the vehicle's pitch angle.
Innovation Solution
A rider-assistance system that includes a peripheral environment detector, an input device, and a controller capable of acquiring pitch angle correction target information and performing correction operations to adjust the support state of the peripheral environment detector, thereby improving detection accuracy.
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 perform driving assistance operations, but the detection becomes inappropriate when the riding state or loaded state is not standard due to significant pitch angle changes
Solution Approach 1:
The support state of the peripheral environment detector is made changeable rather than fixed. The correction operation performing section dynamically adjusts the support state based on pitch angle correction target information, allowing the detector to adapt to different riding states and loaded states that cause pitch angle variations.
Solution Approach 2:
The system changes the parameters of the detector's support state in response to detected pitch angle variations. By acquiring pitch angle correction target information and performing correction operations, the system adjusts physical parameters of the detector's mounting state to compensate for vehicle pitch changes caused by different 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 the riding state or loaded state is not standard
Solution Approach 1:
The system uses feedback from pitch angle correction target information to continuously adjust the detector's support state. This closed-loop approach compensates for pitch angle variations caused by the vehicle's light weight and short wheelbase, maintaining detection precision despite the maneuverability characteristics.
Solution Approach 2:
The detector's support state is made dynamic rather than static, allowing it to adapt to the pitch angle changes that occur during different riding conditions. This dynamic adjustment ensures that the detection precision is maintained even when the vehicle's maneuverability causes significant pitch variations.

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.
