Solution Overview
Problem
Current vehicle sensor systems are limited by the number of sensors that can be implemented, which restricts the accuracy and range of environmental sensing, and sharing sensor information between vehicles can increase costs and complexity.
Innovation Solution
A vehicle-to-vehicle communication network that processes and shares sensor data between entities, using a processor to determine available bandwidth and select appropriate sensor data types for transmission, allowing for enhanced environmental determination while reducing the need for multiple sensors on individual vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are implemented to improve sensing accuracy and range, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges sensor systems across multiple vehicles by establishing a communication network that shares sensor data between vehicles. Instead of each vehicle needing complete sensor coverage, the system combines data from multiple sources to achieve comprehensive environmental sensing, thereby reducing the number of sensors required per vehicle while maintaining or improving overall measurement precision.
Solution Approach 2:
The communication network serves multiple functions: it transmits sensor data between vehicles, enables bandwidth management, supports different data types (raw sensor data, processed data, selective data), and provides a platform for collaborative sensing. This multi-functionality allows the system to achieve enhanced sensing capabilities without proportionally increasing hardware complexity.
2Measurement precision
If multiple sensors are implemented to improve sensing accuracy and range, then measurement precision is improved, but cost increases
Solution Approach 1:
The patent merges sensor systems across multiple vehicles by establishing a communication network that shares sensor data between vehicles. Instead of each vehicle needing complete sensor coverage, the system combines data from multiple sources to achieve comprehensive environmental sensing, thereby reducing the number of sensors required per vehicle while maintaining or improving overall measurement precision.
Solution Approach 2:
The system uses communication networks to copy and transmit sensor data between vehicles. Rather than duplicating physical sensors in each vehicle, the data from sensors in one vehicle is copied and shared with other vehicles, achieving the same effect as having multiple sensors at a fraction of the cost.
3Measurement precision
If high bandwidth sensor data is transmitted to improve environmental determination, then measurement precision is improved, but communication bandwidth requirements increase
Solution Approach 1:
The patent implements dynamic bandwidth management where the system adapts to available communication bandwidth by selecting appropriate data types and transmission priorities. When bandwidth is limited, the system dynamically switches to transmitting processed or selective data rather than raw sensor data, maintaining environmental determination accuracy while adapting to varying bandwidth conditions.
Solution Approach 2:
The system changes data transmission parameters based on available bandwidth. It can transmit different types of sensor data (raw, processed, or selective) depending on bandwidth availability, and can adjust transmission quality, resolution, or frequency to match communication constraints while still providing sufficient information for accurate environmental determination.
Data Source
AI summary
An apparatus includes a processor configured to receive first sensor data from a sensor system of the first entity and a receiver. The receiver is configured to receive second sensor data from a second entity in the vehicle to vehicle network over a communication network and provide the second sensor data to the processor. The second sensor data comprises a first type of sensor data having a first bandwidth requirement. The processor is further configured to determine an available bandwidth of the communication system; and when the first bandwidth requirement exceeds the communication bandwidth, select a second type of sensor data having a second bandwidth requirement. The second bandwidth requirement is less than the first bandwidth requirement. The processor is further configured to process the first and second sensor data to at least partially determine an environment surrounding the first entity.
