Vehicle Slowdown Control via Short Range Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle telematics systems require police officers to relay slowdown commands through a call center, which can lead to delays and inefficiencies during pursuits, as they need to communicate with the call center to issue commands to target vehicles.
Innovation Solution
Enabling direct short-range wireless communication between police vehicles and target vehicles, allowing officers to transmit slowdown commands directly to the target vehicle, thereby bypassing the need for call center intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If police officers relay slowdown commands through a call center, then centralized control and authorization are maintained, but communication delays and intermediary involvement increase during high-pressure pursuits
Solution Approach 1:
The system segments the authorization and command execution functions. The call center provides pre-authorization by enabling the target vehicle's telematics unit to receive slowdown commands, while the pursuing officer's mobile device independently transmits the actual command without real-time call center intervention. This segmentation maintains authorization reliability while eliminating communication delays.
Solution Approach 2:
The call center performs preliminary authorization by enabling the target vehicle's telematics unit before the pursuit begins or at the start of the pursuit. This preliminary action stores authorization data in the vehicle's telematics unit, allowing subsequent slowdown commands to be executed immediately without real-time call center verification, thus reducing response time while maintaining security.
2Adaptability or versatility
If police officers relay slowdown commands through a dispatcher or PSAP, then centralized coordination is achieved, but the number of communication intermediaries increases
Solution Approach 1:
The system extracts the actual command transmission function from the call center and dispatcher infrastructure. The pursuing officer's mobile device directly communicates with the target vehicle's telematics unit using wireless communication protocols, removing the dispatcher and PSAP from the command transmission chain while maintaining centralized authorization through pre-enabling by the call center.
Solution Approach 2:
The telematics unit in the target vehicle acts as an intermediary that stores authorization data and receives commands directly from the pursuing officer's mobile device. This intermediary enables direct peer-to-peer communication between police vehicles while maintaining the security framework established by the call center, reducing the number of active intermediaries during pursuit operations.
Data Source
AI summary
A method and system for enabling police pursuing a vehicle to slow the vehicle down via short range wireless communication with the vehicle. The process can be carried out with or without involvement of a call center that provides telematics services to the vehicle. The method involves configuring the vehicle to accept a slowdown command, confirming the target vehicle at a pursuing police vehicle, establishing the short range connection between the police vehicle and target vehicle, and slowing the target vehicle by sending it the slowdown command over the wireless connection. The call center can enable or disable the slowdown service according to the vehicle owner's wishes.
