Fuel waste variable identification and analysis system

摘要

A novel fuel waste variable identification and analysis system is capable of analyzing real-time on-board diagnostics (OBD) information of a vehicle from a remote monitoring station unit. This novel system analyzes, quantifies, and/or predicts various fuel waste variables for a particular vehicle and its driver. Preferably, various fuel waste variables are normalized with a novel metric called “RPG,” or “engine rotation per minute per gallon of fuel.” Utilizing the RPG as a normalizing factor for fuel waste variable measurements uniquely enables a realistic representation of a driver's fuel wasting behaviors in context of the particular vehicle's inherent, native, and average fuel consumption characteristics. Furthermore, the RPG-normalized fuel waste variables can be quantified as gallons of “wasted fuel” in computer-generated driving pattern analysis reports from the fuel waste variable identification and analysis system to motivate the vehicle operators and the drivers for higher operational fuel efficiencies.

主权项

1. A fuel waste variable identification and analysis system with a remote real-time vehicle on-board diagnostics monitoring, the fuel waste variable identification and analysis system comprising:
a vehicle on-board diagnostics unit connected to an engine control unit or a vehicular control chipset of a vehicle to record, diagnose, and generate engine, vehicle dynamics, and fuel consumption data as a real-time data stream; a fuel waste variable analytics module that receives the real-time data stream from the vehicle on-board diagnostics unit for detailed analysis and calculations of one or more fuel waste variables; a fuel waste variable identification and analytics unit in the fuel waste variable analytics module, wherein the fuel waste variable identification and analytics unit sets threshold values for the fuel waste variables, retrieves historical fuel consumption data from a vehicle-specific OBD data history database, and calculates pre-RPG (engine rotation per minute per gallon of fuel) normalized fuel waste variables, a vehicle-specific RPG value, RPG-normalized fuel waste variables, and a fuel waste percentage value for a selected period of time interval; the vehicle-specific OBD data history database that accumulates, stores, and categorizes vehicle dynamics and fuel consumption data downloaded from the vehicle; and a computer server or another electronic device with a CPU and a memory unit that displays the RPG-normalized fuel waste variables on a display panel in the vehicle or in a remote monitoring station unit.
