Vehicle Speed Notification Controller with Local Pre-Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tracking systems do not effectively provide speed exceeded notifications to users in a timely and localized manner, potentially leading to unnecessary alerts and lack of driver awareness of excessive speed.
Innovation Solution
A speed exceeded notification device integrated with a vehicle's data communications bus, featuring a wireless communications device and a controller that sends remote notifications when a speed threshold is exceeded for a first time period, and provides local pre-warnings for a second, shorter time period, using audible, visual, or tactile notifications to encourage the driver to slow down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote notifications are sent immediately when speed threshold is exceeded, then user awareness of excessive speed is improved, but unnecessary alerts are generated and communications costs increase
Solution Approach 1:
The system performs preliminary local notification through the speaker before sending remote notifications. This preliminary action allows the driver to correct the speeding behavior locally, preventing the need for costly remote notifications and reducing unnecessary alerts to monitoring stations
Solution Approach 2:
The speaker acts as an intermediary between the speed detection system and the remote notification system. It provides a local warning mechanism that mediates between immediate remote alerting and delayed notification, reducing the need for expensive remote communications while maintaining driver awareness
2Loss of information
If remote notifications are sent for all speed exceedances, then complete monitoring is achieved, but driver awareness of immediate speed issues is reduced
Solution Approach 1:
The notification system is segmented into two distinct levels: local notification through the speaker and remote notification to the monitoring station. This segmentation allows the system to provide immediate local feedback to the driver while reserving remote notifications for persistent or severe cases, thereby maintaining both complete monitoring and driver awareness
3Loss of energy
If local pre-warnings are provided before remote notifications, then unnecessary remote alerts are reduced, but device complexity increases
Solution Approach 1:
The speaker is utilized for multiple functions: it serves as both a local warning device for immediate speed corrections and as a trigger for remote notifications when speeding persists. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while still providing effective local pre-warnings

AI summary
A speed exceeded notification device is for a vehicle of a type including a vehicle data communications bus extending throughout the vehicle, and at least one vehicle device generating data related to vehicle speed on the vehicle data communications bus. The speed exceeded notification device may include a wireless communications device, and a controller to be coupled to the vehicle data communications bus. The controller may be for reading the data related to vehicle speed from the vehicle data communications bus, and determining when a vehicle speed exceeds a speed threshold for a first time period. The controller may also be for determining when the vehicle speed exceeds the speed threshold for a second time period less than the first time period and, in response thereto, generating a local vehicle speed exceeded notification. Based thereon, the controller may cooperate with the wireless communications device to send a remote vehicle speed exceeded notification.
