Motorcycle Speed Control for Low-Speed Target Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leaning vehicles, such as motorcycles, experience instability at low speeds, making it difficult to accurately specify a target vehicle for speed control due to variations in the orientation of surrounding environment sensors caused by rider handle operations.
Innovation Solution
A control apparatus and method that adjusts target vehicle specification based on speed information and sensor detection, using an executing section to control speed and a specifying section to change processing according to the vehicle's speed and orientation, ensuring accurate target vehicle identification even during low-speed operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If speed control is executed based on positional relation information between the leaning vehicle and target vehicle, then the speed control function is improved, but the system becomes unable to appropriately specify the target vehicle when the leaning vehicle is at low speed and the rider performs handle operations for balancing
Solution Approach 1:
The patent applies dynamics by making the target vehicle specifying processing adaptive to the vehicle's operating state. The system dynamically adjusts the specification criteria based on whether the vehicle is in low-speed balancing mode or normal operation, allowing the control algorithm to switch between different target selection strategies to maintain accuracy across varying operational conditions
Solution Approach 2:
The patent changes parameters by introducing speed information as a conditional parameter that modifies the target vehicle specification process. When vehicle speed falls below a threshold indicating balancing operations, the system alters the specification logic to prioritize stability and prevent inappropriate target switching, thereby resolving the contradiction between maintaining automated speed control and ensuring accurate target specification
2Stability of the object's composition
If the rider performs handle operations to balance the leaning vehicle at low speed, then the vehicle stability is improved, but the orientation of the surrounding environment sensor varies making it difficult to specify the target vehicle
Solution Approach 1:
The patent applies preliminary action by detecting the vehicle's speed and determining balancing operation status before attempting to specify the target vehicle. By preemptively identifying when the vehicle is in a balancing state, the system can adjust the target specification processing in advance, compensating for the expected sensor orientation variations before they affect target detection accuracy
Solution Approach 2:
The patent introduces speed information and control state determination as an intermediary layer between the sensor detection and target vehicle specification. This intermediary processing layer filters out false target detections caused by handle operations, allowing the system to maintain accurate target specification despite sensor orientation variations during balancing maneuvers
