In-Vehicle Speed Alerting With Custom Severity Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle safety systems lack the ability to customize speeding severity based on individual driver, vehicle, and transported object characteristics, which can impact the safety of route traversal.
Innovation Solution
A system and method that allow for the selective setting of speeding designations by defining delta speed differences or percentage speed differences relative to a reference speed limit, along with corresponding time durations, to ensure safe vehicle traversal. This system includes a computer-readable storage medium with program instructions and processors to provide an interface for defining speeding severity levels, receiving speed data from vehicles, determining corresponding speeding severity levels, and transmitting alerts to vehicles for in-vehicle driver alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed speeding threshold is used for all vehicles, then the system is simple to operate, but it cannot account for individual driver, vehicle, and transported object characteristics that affect safety
Solution Approach 1:
The patent segments the speeding threshold into multiple severity levels (e.g., Level 1, Level 2, Level 3) with progressively stricter thresholds. Each level represents a different degree of speeding severity, allowing the system to differentiate between minor and major violations based on the specific context of driver, vehicle, and cargo characteristics.
Solution Approach 2:
The patent applies local quality by assigning different speeding severity thresholds to different vehicles or drivers based on their specific characteristics. For example, vehicles transporting hazardous materials or inexperienced drivers may be assigned lower (stricter) speeding thresholds, while experienced drivers with stable vehicles may have higher (more lenient) thresholds.
2Reliability
If multiple speeding severity levels are defined with different delta speed differences and time durations, then the system can customize speeding severity based on individual characteristics, but the system complexity increases
Solution Approach 1:
The patent implements dynamic speeding thresholds that automatically adjust based on real-time conditions. The system monitors vehicle speed, duration of speeding, and contextual factors (driver experience, vehicle type, cargo characteristics) to dynamically determine the appropriate severity level and corresponding alert response, rather than using static fixed thresholds.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors speeding events, evaluates them against the defined severity levels, and provides alerts or notifications to drivers. The system also tracks driver responses and behavioral changes over time, using this feedback to refine and adjust severity level definitions for improved safety outcomes.
3Reliability
If speeding alerts are provided for all speeding events, then driver safety is maximized, but driver alert fatigue may occur reducing effectiveness
Solution Approach 1:
The patent applies partial action by providing alerts only for speeding events that meet or exceed specific severity thresholds, rather than alerting for every speeding instance. This selective alerting approach focuses driver attention on the most critical violations while avoiding unnecessary notifications for minor infractions, thereby preventing alert fatigue while maintaining safety.
Solution Approach 2:
The patent changes the parameter of alert triggering from a fixed binary threshold to a multi-level severity scale. By adjusting the delta speed difference and time duration parameters for different severity levels, the system optimizes alert generation to balance safety requirements with driver responsiveness, ensuring alerts are meaningful and actionable.
Data Source
AI summary
An improved system and method of defining speeding severity levels, receiving over a wireless network from a vehicle device speed data and metadata, determining associated speeding severity levels, based at least in part on the determined associated speeding severity levels, determining whether an alert communication is to be transmitted the vehicle device, and in response to determining that an alert communication is to be transmitted the vehicle device, transmitting the alert communication via a wireless interface to the vehicle device, the alert communication configured to cause the vehicle device to provide a corresponding in-vehicle alert.
