Steering Assistance Using Preceding Vehicle Path Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle driving assistance systems are ineffective when lane division lines are absent or when vehicles turn at intersections, as they rely on these lines for steering assistance.
Innovation Solution
A vehicle driving assistance system that applies a steering force to help the vehicle turn in the same direction as a preceding vehicle at an intersection, using a combination of forward information acquisition, turning intention recognition, and steering-force control to mimic the preceding vehicle's path, even in the absence of lane division lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system relies on lane division lines for steering assistance, then the steering control is simple and reliable, but the system becomes ineffective when lane division lines are absent or when vehicles turn at intersections
Solution Approach 1:
The system copies the traveling track of the preceding vehicle to generate steering assistance. Instead of relying on lane division lines, the system acquires forward information about the preceding vehicle, identifies its traveling track, and uses this copied track as the basis for steering control, enabling effective operation in environments without lane markings
Solution Approach 2:
The system achieves multi-functionality by being able to operate in both environments with and without lane division lines. When lane lines are present, the system can use them for steering assistance; when they are absent or at intersections, the system automatically switches to using the preceding vehicle's traveling track, making the steering assistance universally applicable across different driving scenarios
2Device complexity
If the system uses lane division lines for steering control, then the control mechanism is simple, but it cannot assist turning at intersections where lane lines discontinue
Solution Approach 1:
The system identifies the traveling track of the preceding vehicle by acquiring forward information and copying this track for steering assistance. This approach eliminates the need for complex intersection detection and lane line recognition, maintaining relatively simple control mechanics while enabling effective turning assistance at intersections
Solution Approach 2:
The preceding vehicle's traveling track serves as an intermediary that bridges the gap between the absence of lane division lines and the need for steering guidance. By using the preceding vehicle's path as a reference, the system provides continuous steering assistance through intersections without requiring complex intersection-specific control mechanisms

AI summary
A vehicle driving assistance system, including: a forward information acquirer; a turning intention receiver; a steering-force applying device; and an assistance processing executing device including an identifying portion for identifying a traveling track of a preceding vehicle, a recognizing portion for recognizing turning of the preceding vehicle to the right or the left, a recognizing portion for recognizing turning of an own vehicle and a direction of the turning, and a steering-force control portion for executing a steering-force control in turning in which the applying device applies a steering force for assisting the turning of the own vehicle along an identified traveling track, when the recognized turning of the preceding vehicle is turning at an intersection present on a traveling path of the own vehicle and a direction of the turning of the preceding vehicle at the intersection coincides with the recognized direction of the turning of the own vehicle.
