Lean Vehicle Cruise Control for Cornering Gap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lean vehicles, such as motorcycles, face challenges in maintaining an appropriate positional relationship with preceding vehicles due to their smaller size and high degree of freedom in travel position, which can lead to issues like loss of sight and compromised safety during cornering.
Innovation Solution
A controller that adjusts the positional relationship between a lean vehicle and a preceding vehicle by executing adaptive cruise control, taking into account whether the lean vehicle is cornering, by changing the target inter-vehicle distance or passing time difference based on cornering status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lean vehicle maintains a standard target positional relationship with the preceding vehicle, then the positional relationship can be consistently controlled under normal conditions, but the positional relationship becomes inappropriate when the lean vehicle is cornering
Solution Approach 1:
The target positional relationship is made dynamic by changing it based on the cornering determination result. The execution section adjusts the target positional relationship according to whether the lean vehicle is cornering, allowing the system to adapt to different driving conditions rather than maintaining a fixed target distance
Solution Approach 2:
The control system changes the target positional relationship parameter based on the cornering state. When cornering is detected, the target positional relationship is modified to account for the vehicle's movement characteristics during cornering, ensuring appropriate spacing is maintained
2Device complexity
If the lean vehicle uses a fixed target inter-vehicle distance for adaptive cruise control, then the control system is simple to implement, but the safety is compromised when the vehicle corners
Solution Approach 1:
The system performs preliminary cornering determination before adjusting the target positional relationship. By detecting cornering in advance and proactively changing the target distance, the system prevents safety issues rather than reacting after they occur
Solution Approach 2:
The control system uses feedback from the cornering determination section to continuously adjust the target positional relationship. The execution section receives information about whether the vehicle is cornering and modifies the target distance accordingly, creating a closed-loop control system that responds to actual driving conditions

AI summary
The invention obtains a controller and a control method capable of appropriately adjusting a positional relationship between a lean vehicle and a preceding vehicle. In a controller (20) and the control method according to the invention, an execution section of the controller (20) executes positional relationship adjustment operation to adjust a positional relationship between a lean vehicle (1) and a preceding vehicle located in front of the lean vehicle (1) to a target positional relationship. Furthermore, a determination section of the controller (20) determines whether the lean vehicle (1) is cornering. The execution section changes the target positional relationship according to whether the lean vehicle (1) is cornering.
