Vehicle Speed Limiter with Dynamic Location-Based Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles often exceed designated speed limits without effective prevention, relying on policing authorities, as existing speed limiting systems may allow speeds higher than intended limits.
Innovation Solution
A vehicle speed control system that uses a speed limiter communicatively coupled with a vehicle management system, incorporating a speed signal processor and a speed threshold generator to enforce a pre-determined speed threshold based on the vehicle's location and designated speed limits, ensuring the vehicle operates within a set speed limit plus a user-defined buffer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a throttle governor or maximum speed limiter is configured to prevent the vehicle from traveling above a top desired speed, then the vehicle speed can be controlled, but the top desired speed dictated by the governor is often far higher than the designated speed limit in some areas
Solution Approach 1:
The speed limiter dynamically adjusts the speed threshold based on the vehicle's real-time location. The system retrieves location data from GPS and compares it with a database of speed limits for different geographic areas, automatically adapting the speed threshold to match local regulations. This resolves the contradiction by making the speed control system both reliable (enforcing limits) and adaptable (adjusting to different locations).
Solution Approach 2:
The system continuously monitors the vehicle's location and speed, comparing actual speed against the retrieved speed limit for the current location. When the vehicle approaches or exceeds the limit, the system provides feedback by modifying the speed signal to the ECU. This closed-loop feedback mechanism ensures reliable enforcement while adapting to different geographic speed limits.
2Reliability
If the speed limiter compares the combination of speed signal and sensed speed with a stored threshold speed, then the vehicle speed can be limited to the threshold, but the system requires integration of multiple components including speed signal processor, location generator, and speed database
Solution Approach 1:
The system merges multiple functions into an integrated speed control architecture. The speed limiter combines the speed signal processor, location generator, speed database, and ECU communication into a unified system that operates through a single control unit. This merging reduces overall system complexity while maintaining reliable speed limit enforcement through coordinated operation of integrated components.
Solution Approach 2:
The speed limiter serves multiple functions simultaneously: it processes speed signals from the accelerator sensor, generates location data via GPS, retrieves appropriate speed limits from the database, compares actual speed against thresholds, and communicates with the ECU. This multi-functionality consolidates what would otherwise be separate systems into a single versatile component, reducing complexity while ensuring reliable enforcement.

AI summary
One or more techniques and/or systems are disclosed for limiting a speed of a vehicle. A speed control device, operably coupled with a vehicle management system, can be configured to limit an engine speed based at least upon: an identified speed of the vehicle; a pre-determined speed limit for a location of the vehicle, identified in real-time; and a pre-determined speed threshold for the vehicle. A networking component, communicatively coupled with the speed control device, can be configured to communicate wirelessly with a remote computing device to provide the speed threshold information from the remote computing device to the speed control device, and to provide vehicle-related information to the remote computing device. Additionally, the remote computing device can comprise an application that allows a user to provide the speed threshold information and receive the vehicle-related information.
