Lean Vehicle Following Control for Cornering Visibility
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 of the preceding vehicle during cornering and compromised driving safety.
Innovation Solution
A controller that adjusts the positional relationship between a lean vehicle and a preceding vehicle by determining whether the lean vehicle is cornering, and adjusts the target positional relationship accordingly, such as shortening the inter-vehicle distance during cornering to maintain visibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lean vehicle maintains a standard inter-vehicle distance for positional relationship adjustment, then the general driving safety is ensured, but the rider may lose sight of the preceding vehicle during cornering
Solution Approach 1:
The patent applies dynamics by making the target inter-vehicle distance variable rather than fixed. The execution section dynamically adjusts the target inter-vehicle distance based on cornering detection: using a first value during cornering and a second value when not cornering. This dynamic adjustment ensures the rider maintains visibility of the preceding vehicle during cornering while preserving normal safety distances during straight driving.
2Adaptability or versatility
If the lean vehicle has high degree of freedom in travel position, then the vehicle's maneuverability is improved, but the positional relationship with preceding vehicle becomes unstable
Solution Approach 1:
The patent implements feedback by continuously monitoring the vehicle's cornering state through detection sections and using this information to adjust the target inter-vehicle distance. The determination section detects whether the vehicle is cornering, and this feedback loop enables the execution section to automatically adjust the positional relationship target, stabilizing the relationship despite the vehicle's high maneuverability and freedom in travel position.

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.
