Blind Spot Detection Using Adjacent Vehicle Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles often have blind spots that drivers cannot see through mirrors, increasing the risk of collisions when another vehicle enters or is in the blind spot, especially since not all vehicles are equipped with blind spot warning systems, and existing systems may not activate under all circumstances.
Innovation Solution
Equipping vehicles with sensors such as cameras, ultrasonic sensors, and radar to detect and calculate blind spots of adjacent vehicles, and using this data to alert the driver and potentially adjust the vehicle's path to avoid the blind spot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If vehicles rely on mirrors to see regions behind and to the side, then the driver can visualize most areas, but blind spots remain where the driver cannot directly visualize
Solution Approach 1:
The patent uses sensors (cameras, ultrasonic sensors, radar) as intermediary devices to detect vehicles in blind spot regions that are not directly visible to the driver through mirrors. These sensors act as mediators between the driver and the blind spot areas, providing indirect visualization through electronic warnings when other vehicles are detected in regions that cannot be seen by traditional mirrors.
2Reliability
If blind spot warning systems are equipped in all vehicles, then collision risk is reduced, but device complexity and cost increase
Solution Approach 1:
The patent describes a universal blind spot detection system that can be implemented in various vehicle types using standardized sensor components. The system uses multi-functional sensors (cameras, ultrasonic sensors, radar) that can serve both blind spot detection and other auxiliary driving functions, reducing overall system complexity while maintaining reliability across different vehicle platforms.
Solution Approach 2:
The blind spot detection system is segmented into multiple independent sensor modules (camera module, ultrasonic sensor module, radar module) that can be selectively deployed. This segmentation allows the system to achieve reliable collision avoidance through multiple detection zones while managing complexity by allowing gradual implementation and selective activation of different sensor types based on specific driving conditions.
3Loss of information
If existing blind spot warning systems are used, then some blind spots are detected, but the systems may not activate under all circumstances
Solution Approach 1:
The patent implements a dynamic blind spot warning system that continuously adjusts its detection and warning activation based on real-time driving conditions. The system dynamically changes its sensitivity and activation thresholds depending on factors such as vehicle speed, relative position of detected vehicles, and environmental conditions, ensuring warnings are provided under all relevant circumstances rather than being limited to fixed activation conditions.
Solution Approach 2:
The system changes multiple parameters including detection sensitivity, warning threshold distances, and sensor activation levels based on driving conditions. For example, the system adjusts detection ranges and warning triggers according to vehicle speed, traffic density, and relative positioning, allowing comprehensive blind spot detection coverage across diverse operating scenarios while maintaining adaptability to different driving contexts.
