Driving Assistance Apparatus Smooth Track Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving assistance systems experience discomfort for drivers when switching between lane division line and preceding vehicle tracking due to increased vehicle movement, leading to noticeable deviations and discomfort.
Innovation Solution
A driving assistance apparatus that determines both a first traveling track based on road infrastructure and a second traveling track based on a preceding vehicle's path, stores deviation information, and forms a target track to minimize the deviation between the two tracks when switching, thereby reducing driver discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system switches between lane division line tracking and preceding vehicle tracking, then the vehicle can maintain continuous guidance, but the driver experiences discomfort due to increased vehicle movement and noticeable deviations
Solution Approach 1:
The system performs preliminary actions by storing deviation information between lane division line tracking and preceding vehicle tracking before a switch occurs. This pre-stored information is then used to smooth the transition when switching between tracking methods, preventing sudden vehicle movements and maintaining driver comfort while ensuring continuous guidance.
2Measurement precision
If the system uses lane division lines for tracking, then the vehicle can follow the intended lane, but the lane division line may become unrecognizable due to discontinuity, fading, or road surface conditions
Solution Approach 1:
The system uses preceding vehicle tracking as an intermediary method when lane division line recognition fails. By switching to follow the preceding vehicle's trajectory, the system maintains continuous and reliable tracking even when lane markings are discontinuous, faded, or obscured by road surface conditions.
Solution Approach 2:
The system changes the tracking parameter from lane division line coordinates to preceding vehicle trajectory when the former becomes unrecognizable. This parameter switching allows the system to maintain measurement precision and tracking continuity under varying road conditions.
3Adaptability or versatility
If the system switches tracking targets from lane division line to preceding vehicle, then guidance can be maintained, but the switching itself causes increased vehicle movement and driver discomfort
Solution Approach 1:
The system performs preliminary actions by pre-storing deviation information between different tracking methods before switching is needed. This allows the transition to be smoothed using the pre-calculated deviation data, reducing the impact of switching on driver comfort while maintaining the flexibility to adapt between different tracking methods.

AI summary
An apparatus for assisting in the driving of a vehicle determines, for a first vehicle, a first traveling track based on road infrastructure and a second traveling track based on the traveling track of a second vehicle that precedes the first vehicle. The apparatus stores information about the first traveling track and the second traveling track such that the deviation corresponds to the respective traveling positions of the vehicles. If a base for formation of a target track that the first vehicle is caused follow is switched between the first traveling track and the second traveling track when the apparatus forms this target track, the apparatus forms the target track based on the deviation information to decrease deviation between the first traveling track and the second traveling track.
