Speed Notification Controller for Vehicle Bus Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle tracking systems lack a comprehensive solution for providing timely and localized speed exceeded notifications to both drivers and remote authorities, which can lead to unnecessary alerts and inefficient communication of excessive speed events.
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, while also generating local notifications for a shorter second time period to alert the driver, thereby preventing excessive remote alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote notifications are sent for every speed threshold exceedance, then complete monitoring coverage is achieved, but unnecessary alerts and communication overhead increase
Solution Approach 1:
The system performs preliminary local notification through vehicle indicators before sending remote notifications. This preliminary action allows the driver to correct the speeding behavior immediately, preventing the need for remote alert communication in many cases.
Solution Approach 2:
The notification system is segmented into two levels: local notifications via vehicle indicators for immediate driver feedback, and remote notifications via wireless communication for persistent violations. This segmentation divides the monitoring function to optimize resource usage.
2Ease of operation
If local notifications are provided to drivers, then drivers can adjust speed in real-time, but the system complexity increases
Solution Approach 1:
The controller leverages the existing vehicle data communications bus and existing vehicle indicators, making the system multi-functional by using already-present vehicle components for both their original purposes and for speed monitoring notifications.
Solution Approach 2:
The system uses the vehicle's own existing infrastructure (data bus and indicators) to provide notifications, rather than requiring entirely separate notification hardware. This self-service approach reduces overall system complexity.
3Ease of manufacture
If speed monitoring uses existing vehicle data bus, then integration is simplified, but access to speed data requires controller coupling to the bus
Solution Approach 1:
The controller is designed to interface with the universal vehicle data communications bus, allowing it to access speed data and other vehicle parameters through a standard interface that serves multiple functions including engine control, transmission control, and now speed monitoring.

AI summary
A speed exceeded notification device may be installed in a vehicle of a type including a vehicle data communications bus extending throughout the vehicle, and at least one vehicle indicator coupled to 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 determining when a vehicle speed exceeds a speed threshold for a first time period, and based thereon may cooperate with the wireless communications device to send a remote vehicle speed exceeded notification. The controller may also determine when the vehicle speed exceeds the speed threshold for a second time period less than the first time period, and may generate a local vehicle speed exceeded notification using the at least one vehicle indicator coupled to the vehicle data communications bus so that a driver of the vehicle can reduce the speed of the vehicle and avoid sending of the remote vehicle speed exceeded notification.
