Motorcycle Distance Control Target Selection in Staggered Riding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distance control systems for single-lane motor vehicles, such as motorcycles, are not optimized for group riding scenarios where lateral offsets between vehicles are significant, leading to suboptimal automatic distance adjustments and potential discomfort for motorcyclists.
Innovation Solution
A method that utilizes environmental sensors to detect the presence of multiple vehicles ahead, determining lateral offsets to select the appropriate target object for distance control, allowing for driver-independent adjustments in braking or engine torque to maintain a comfortable distance, particularly by selecting the vehicle with the smallest lateral offset as the target when risks are minimized.

Engineering Contradiction Analysis
1Ease of operation
If the distance control system always selects the closest vehicle as the target object, then the longitudinal distance can be regulated, but the system does not account for lateral offset and may cause unnecessary braking interventions when vehicles are riding in a staggered formation
Solution Approach 1:
The system dynamically adapts the target object selection based on real-time lateral offset measurements. When the lateral offset exceeds a threshold indicating a staggered formation, the system switches to selecting a different target vehicle than the closest one, making the distance control behavior adaptable to different riding formations rather than following a fixed rule
Solution Approach 2:
The system changes the selection criterion parameter from purely longitudinal distance to a combination of longitudinal distance and lateral offset. By evaluating both parameters and applying threshold comparisons, the system determines which vehicle should be the target object, allowing different behavior for different spatial configurations
2Measurement precision
If the system detects multiple vehicles and determines lateral offsets to select the target object, then the distance control becomes more accurate for group riding, but the system complexity increases
Solution Approach 1:
The target selection process is segmented into distinct evaluation stages: first detecting vehicles in the longitudinal direction, then determining lateral offsets for each detected vehicle, comparing lateral offsets against thresholds, and finally selecting the target object based on the comparison results. This segmentation makes the complex selection process more manageable and implementable
Solution Approach 2:
The lateral offset measurement acts as an intermediary parameter that mediates between the raw sensor data and the target object selection decision. By introducing this intermediate evaluation step, the system can accurately distinguish between vehicles in staggered formations versus those in direct succession, improving selection accuracy without requiring overly complex direct comparison logic
3Measurement precision
If the lateral offset threshold is set to be sensitive, then the system can distinguish staggered formations from direct following, but false positives may occur in normal lane changes
Solution Approach 1:
The system applies a hysteresis effect through threshold comparison, where the lateral offset must exceed a clearly defined threshold to trigger the staggered formation mode. This creates a buffer zone that prevents switching between modes for small, normal variations in lateral position, cushioning against false positives while maintaining precision for genuine formation changes

AI summary
The invention relates to a method for selecting the target object for automatic distance control of a single-track motor vehicle, in which method the presence of a second single-track motor vehicle driving directly ahead in the same lane and a third single-track motor vehicle driving directly ahead of the second single-track motor vehicle is detected by means of an environment sensor system. The lateral offset of the second single-track motor vehicle and of the third single-track motor vehicle with respect to the single-track motor vehicle is determined and the target object for the method for distance control is selected in accordance with at least one of the lateral offsets.
