Lean Vehicle Following Control During Accelerator Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lean vehicles, such as motorcycles, face challenges in optimizing the positional relationship with vehicles ahead, particularly during accelerator operations, which can lead to unsafe proximity and potential collisions.
Innovation Solution
A controller and control method that includes speed control and safety determination to adjust the positional relationship between a lean vehicle and a vehicle ahead, executing speed adjustment assistance when following safety is below standard, using sensors and control units to manage inter-vehicle distance and relative speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speed control is executed to maintain target positional relationship during accelerator operation, then the positional relationship between lean vehicle and vehicle ahead is optimized, but the following safety may be compromised when the lean vehicle travels near the vehicle ahead
Solution Approach 1:
The determination section continuously monitors the actual positional relationship between the lean vehicle and vehicle ahead, comparing it with the target state, and triggers speed adjustment assistance when safety thresholds are violated, creating a closed-loop feedback system that dynamically ensures following safety
Solution Approach 2:
The system performs preliminary safety assessment by determining whether the lean vehicle is traveling near the vehicle ahead before executing speed adjustment assistance operation, preventing unsafe situations before they occur rather than reacting after collision risk arises
2Productivity
If the lean vehicle travels near the vehicle ahead during accelerator operation, then the productivity and responsiveness are improved, but the safety risk increases significantly
Solution Approach 1:
The system dynamically adjusts the control strategy based on real-time safety assessment, transitioning from normal speed control to speed adjustment assistance operation when the lean vehicle travels near the vehicle ahead, making the safety mechanism adaptive rather than static
Solution Approach 2:
The determination section acts as an intermediary that assesses safety conditions and mediates between the accelerator operation responsiveness and collision risk prevention, deciding when to activate speed adjustment assistance without directly interfering with normal driving operations

AI summary
The invention obtains a controller and a control method capable of optimizing a positional relationship between a lean vehicle and a vehicle ahead. In the controller and the control method according to the invention, at least during an accelerator operation by a rider, an execution section of the controller executes, as rider-assistance operation to assist with driving by the rider, speed control for controlling a speed of a lean vehicle (1) such that a positional relationship between the lean vehicle (1) and a vehicle ahead (2) located ahead of the lean vehicle (1) approaches a target state that varies according to an operation amount of the accelerator operation. Furthermore, a determination section of the controller determines following safety of the lean vehicle (1) to follow the vehicle ahead (2). During execution of the speed control, in the case where the determination section determines that the following safety is lower than a standard, the execution section executes speed adjustment assistance operation as operation to assist with speed adjustment for moving the lean vehicle (1) away from the vehicle ahead (2).
