Blindspot Warning Using HD Maps and Adjacent Vehicle Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blind areas formed by vehicles in adjacent lanes can obstruct a driver's view, leading to potential accidents without warning, as existing technologies do not effectively alert drivers to these hazards.
Innovation Solution
A vehicle apparatus equipped with a GPS module, camera, sensors, and a processor that detects and computes the driving speed and relative speed of adjacent vehicles, determining the existence of blind areas and providing warnings or controlling the vehicle to maintain safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles are present in adjacent lanes, then blind areas are formed blocking driver view, but no warning is provided to the driver
Solution Approach 1:
The system continuously monitors the positions and speeds of adjacent vehicles using sensors and cameras, processes this information to determine blind area formation, and provides real-time feedback to the driver through visual, auditory, or haptic warnings. This closed-loop feedback mechanism ensures the driver is informed of previously undetected blind area hazards
Solution Approach 2:
The patent introduces an intermediary warning system that mediates between the physical presence of adjacent vehicles and the driver's perception. The system acts as a mediator by detecting vehicle positions, calculating blind area formation, and translating this information into comprehensible warning signals for the driver, bridging the information gap
2Measurement precision
If the system monitors adjacent vehicles and computes speeds, then blind area detection capability is improved, but device complexity increases
Solution Approach 1:
The system employs multi-functional sensors and cameras that serve multiple purposes: detecting adjacent vehicles, measuring their positions, computing their speeds, and determining blind area formation. This multi-functionality reduces the need for separate dedicated components for each measurement task, thereby limiting the increase in device complexity while maintaining high measurement precision
Solution Approach 2:
The patent combines multiple detection functions into an integrated system where sensors and cameras work together to simultaneously gather position and speed information of adjacent vehicles. The processing unit merges data from multiple sources to comprehensively determine blind area formation, reducing overall system complexity through functional integration

AI summary
A method for providing driving assistance by detecting and warning against areas on one or other side of the road which are obscured by vehicles in other lanes is based on a HD map and includes acquiring location and driving speed of a vehicle which is carrying an apparatus applying the method. The system of the method includes at least one sensor, and environmental information as to surroundings is acquired with location. The speeds of other vehicles relative to the driving speed of the vehicle are calculated, and an instruction to the driver is generated the speed of the vehicle is less than a first predefined value but the speed of the vehicle relative to the driving speeds of the other vehicles is larger than a second predefined value. The apparatus applying the method is also disclosed.
