Patent Images
1. A method comprising:
- in a circuit within a vehicle,communicating with a vehicle diagnostics system to obtain data relating to the operation of the vehicle from the vehicle diagnostics system while the vehicle is being driven via driver control inputs,using the obtained data to determine operational characteristic data including at least one of emissions data and data characterizing a prediction of actual fuel used, andusing the determined operational characteristic data to generate data that characterizes a driver control input that influences at least one of emissions or fuel use.

Abstract
The present invention provides an onboard system for determining vehicle emissions. The emissions are determined in real-time and may be transmitted to a remote terminal for storage and/or analysis. Data is supplied solely to an emissions unit from a vehicle diagnostic system: the vehicle diagnostic system receives vehicle data from vehicle systems and sub-systems.

7. An apparatus for predicting actual fuel used by a vehicle having an engine controller that controls at least one fuel-based operational characteristic of the vehicle, the apparatus comprising:
-
an emissions unit communicatively coupled to a vehicle diagnostic unit and configured and arranged to receive data characterizing fuel-based operational characteristics of the vehicle from the vehicle diagnostic unit; and a processing unit configured and arranged to use the data received from the vehicle diagnostic unit to determine the fuel consumption of the vehicle, independently from any calculations done inside the engine controller. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A method of analyzing driving inputs provided for operating a vehicle having a vehicle diagnostics system connected to a GPS receiver, the method comprising:
-
obtaining data relating to the operation of the vehicle from the vehicle diagnostics system and the GPS receiver while the vehicle is being driven, using the obtained data on-board the vehicle to identify and use at least one of the speed, time and distance travelled with data received via the vehicle diagnostics system and the GPS receiver to detect a characteristic of the driving inputs and routes travelled to provide data for monitoring usage of the vehicle.

17. An apparatus for characterizing driver-inputs for operating a vehicle independent from any calculations done in a vehicle engine controller, the apparatus comprising:
-
an emissions unit configured and arranged to couple to a vehicle diagnostic unit via a diagnostic port and to obtain information pertaining to the operation of the vehicle from the vehicle diagnostics unit; a GPS receiver connected to the vehicle diagnostics unit; and an on-board processing unit configured and arranged to interpret data received from the vehicle diagnostic unit via the emissions unit, the interpreted data characterizing the driver-inputs, and to transmit the interpreted data for access by a remote terminal. - View Dependent Claims (18)
