Motorcycle Distance Control Target Selection for Lateral Offsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic distance control systems for single-track motor vehicles, such as motorcycles, are limited in their ability to manage lateral offsets and adjust distances comfortably when driving in groups, as they typically only account for a single preceding vehicle, neglecting the risk assessment and adjustment needed for vehicles driving in parallel or offset positions.
Innovation Solution
A method and device for automatic distance control that detects the presence of two preceding single-track motor vehicles using a surroundings sensor system, determining their lateral offsets, and selects a target object for distance control based on these offsets, allowing for independent braking or engine torque adjustments to maintain a predefined distance, which can be influenced by speed variables.

Engineering Contradiction Analysis
1Adaptability or versatility
If the distance control system only accounts for a single preceding vehicle, then the system complexity is reduced and operation is simpler, but the system cannot properly manage lateral offsets and adjust distances when driving in groups
Solution Approach 1:
The system dynamically adapts its behavior based on the detected driving situation. When a single vehicle is detected, the system operates in simple mode. When multiple vehicles with lateral offsets are detected, the system automatically switches to group driving mode, adjusting the target object selection based on lateral offset thresholds. This dynamic adaptation resolves the contradiction by allowing the system to be simple when needed and complex when required.
Solution Approach 2:
The system changes its operational parameters based on the detected scenario. By introducing lateral offset as a new parameter and comparing it against predefined thresholds, the system can distinguish between single-vehicle and group-driving scenarios. This parameter-based approach allows the system to adapt its target selection logic without requiring fundamentally different system architectures.
2Adaptability or versatility
If the system detects and evaluates multiple preceding vehicles with lateral offsets, then the adaptability for group driving is improved, but the complexity of detection and measurement increases
Solution Approach 1:
The system introduces lateral offset as an additional measurement parameter beyond the standard longitudinal distance. By defining specific threshold values for lateral offset, the system can automatically categorize detected vehicles into different roles (target object vs. non-target) based on their lateral positions. This parameter-based classification simplifies the complexity of multi-vehicle detection.
Solution Approach 2:
The system segments the detected vehicles into different categories based on their lateral offset from the ego vehicle's path. Vehicles within the threshold are identified as potential target objects, while those outside the threshold are treated as non-target vehicles. This segmentation approach breaks down the complex task of multi-vehicle monitoring into manageable categories with distinct handling rules.
3Ease of operation
If the system adjusts distance to the directly preceding vehicle regardless of lateral offset, then the control operation is simpler, but the safety and comfort in group driving scenarios deteriorates
Solution Approach 1:
The system dynamically adjusts its target selection based on the lateral offset of detected vehicles. In normal operation, the directly preceding vehicle is the target. However, when a vehicle with significant lateral offset is detected, the system automatically switches to selecting a different target object (the vehicle closer to the center of the group). This dynamic target selection maintains operational simplicity while ensuring safety and comfort in group driving scenarios.

AI summary
A method for selecting the target object for an automatic distance control of a single-track motor vehicle. The presence of a second single-track motor vehicle preceding directly in the same lane and a third single-track motor vehicle preceding directly the second single-track motor vehicle are detected with the aid of a surroundings sensor system. The lateral offset of the second single-track motor vehicle and of the third single-track motor vehicle are ascertained with regard to the single-track motor vehicle. The target object being selected for the method for distance control as a function of at least one of the lateral offsets.
