Motorcycle Turn Control That Cancels Auto Throttle on High Lateral G
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddle-type vehicles face difficulties in handling automatic deceleration or acceleration during turning, as the center of gravity shifts and cornering forces can cause tire slipping, making it challenging for riders to manage the vehicle's behavior.
Innovation Solution
A controller that acquires trigger information and lateral acceleration data to adjust behavior control operations, canceling the control when lateral acceleration exceeds a reference value to prevent tire slipping and maintain grip characteristics during turning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the controller performs automatic deceleration or automatic acceleration during turning travel, then the driving assistance function is improved, but the tire grip stability deteriorates due to center of gravity shift and cornering forces
Solution Approach 1:
The control system dynamically adjusts its operation based on real-time detection of lateral acceleration. When lateral acceleration exceeds a threshold during turning, the system automatically cancels the automatic deceleration/acceleration function, thereby adapting to changing grip conditions and preventing tire slip
Solution Approach 2:
The system continuously monitors lateral acceleration as feedback from the turning state, and uses this feedback to determine whether to maintain or cancel the behavior control operation. This closed-loop control ensures the system responds appropriately to grip condition changes during turning

AI summary
The present invention obtains a controller and a control method capable of appropriately assisting with driving by a rider. In the controller and the control method according to the present invention, an acquisition section of a controller (60) acquires lateral acceleration information of a traveling straddle-type vehicle (100), and in a control mode in which behavior control operation to make the straddle-type vehicle (100) automatically decelerate or automatically accelerate is performed, an execution section of the controller (60) changes the behavior control operation according to the lateral acceleration information.
