Abstract: Diesel fuel consumption is calculated in real-time in an vehicle diagnostic monitor using standard OBDII reported parameters and publicly available engine characteristics. Also, fuel consumption in vehicles that maintain a constant air-fuel ratio is calculated by analyzing the subject engine as an air pump and reading publicly available OBDII diagnostic data to estimate the instantaneous airflow through the engine without the need of MAF sensor data.

Abstract: A system for assessing fitness of drivers for trip assignments includes a data processor adapted to communicate with recorders in vehicles for retrieving driving histories of drivers, and a terminal connected with the data processor. The terminal is used by a dispatcher for operating the data processor to construct trip definitions of pending trip assignments, append each of the trip definitions separately to the driving history of each of the drivers so as to form driver/trip assignment combinations of all drivers and all pending trip assignments, process the combinations through an hours-of-service engine to determine which combinations are legal under hours-of-service work rules, calculate a fitness rating for each legal combination, and analyze the fitness ratings of the legal combinations against one another to select the driver with best fitness for each pending trip assignment.

Abstract: A system for job management between mobile devices includes a processor configured to store in a storage messages and data pertaining to job assignments and reassignments to build a historical record concerning each job assignment and reassignment, to receive from a dispatch terminal requests containing messages and data pertaining to creating and allocating job assignments and reassignments at and between mobile devices, to communicate via a communication interface with the mobile devices, to execute the requests by creating and allocating the job assignments and reassignments at and between the mobile devices, and to output to a storage the messages and data pertaining to the allocation of job assignments and reassignments in order to add to and maintain the historical record in the storage concerning each job assignment and reassignment with respect to the mobile devices.

Abstract: An interface device includes a processor, a memory communicating with the processor and containing indicators of vehicle operational parameters from which a user may select to set up filters, a communication module communicating with the processor, and a plurality of protocol bus modules supporting different multiple vehicle diagnostic protocols and have multiple filters for set up in correspondence with the indicators of user-selected parameters. The processor is configured to control the memory and modules to cooperate with one another to find the correct protocol out of multiple supported protocols, define the indicators of user-selected parameters by saving user-initiated filter setups, read data regarding user-selected parameters from a vehicle diagnostic communication port according to the filter setups, and output messages regarding the user-selected parameters.

Abstract: A method of sensing vehicle engine ignition status is disclosed wherein samples of only the electrical system voltage levels are used. Sampling voltages that drop sufficiently (in magnitude and quantity over a period of time) will signify an “engine off” state.

Abstract: The user configures to process at least two data sources without depending on preprogrammed functions or resorting to reprogramming the basic software of the device.

Abstract: The acceleration of a mobile asset is sensed and compared to threshold acceleration levels when the speed of the mobile asset is above a threshold speed. When the acceleration exceeds a threshold a report is created allowing aggressive driving behavior to be logged.

Abstract: A wireless device for facilitating for GPS-based asset tracking via a wireless communications network and a centralized management system. The wireless device includes dynamically configurable event profiles which allow the wireless device to be dynamically reconfigured and to perform certain actions based on a dynamically configurable combination of received events.

Abstract: Data flow from a vehicle telematics device to a remote host, rationalized regardless of the source of the data and its format. Disclosed is a method to unify and process data from multiple sources into singular information for use within the telematics device for vehicle usage data, driver performance, and location data.
