| 20100179721 | ENGINE MONITORING - A method and device for creating an accurate simulation or model of the performance of a vehicle or an internal combustion engine in accordance with the invention comprises accessing the engine on-board diagnostic port (OBD), reading data from the desired industry standard parameter indicators (PID), using these data to produce a basic simulation of the engine operating characteristics, accessing and reading non-industry standard PIDs and using the output from the basic simulation in order to identify the non-industry standard PIDs with a high degree of certainty. As it may not be possible to identify some or all of the required non-industry standard PIDs or their scale due to timing delays or coding, an additional feature of the invention is to prompt a driver of a vehicle to drive the vehicle in a certain way or to perform a certain operation of the engine in order to trigger an event which will assist in identifying the missing non-industry standard PID(s) or will increase the degree of correlation or certainty in identifying the function or the scale of the said non-industry standard PID. | 07-15-2010 |
| 20100023292 | CALIBRATION TOOL - The invention provides a calibration tool for a vehicle monitoring device, the tool having a processor with a clock or access to a time signal and arranged for connection to and to receive and process signals from a vehicle on-board diagnostics unit (OBD), the processor having or connected to means for storing data relating to the vehicle and its engine and codes relating to signals from the available OBD outputs and inputs, the processor being programmed to calculate and store certain coefficients derived over the vehicle's operating range and to populate an array with the said coefficients so that the processor can look up the corresponding co-efficient from the array to calculate the desired value or output. The invention extends to a method of calibrating a calibration tool or a vehicle-monitoring device mounted in a vehicle provided with such a calibration tool. The method comprises the steps of configuring the calibration tool to receive data from vehicle sensors including those indicating vehicle road and engine speed data and temperature data, operating the vehicle, processing the data received during operation of the vehicle to calculate coefficients specific to the vehicle, and populating look-up tables that are accessible to the vehicle monitoring device with the calculated coefficients. | 01-28-2010 |
