Vehicular diagnostic system
First Claim
1. An apparatus comprising:
- a communication circuit configured and arranged to couple to and communicate with a vehicle on board diagnostics (OBD) circuit;
a data acquisition module configured and arranged to acquire data from signals generated by the OBD and received via the communication circuit, the signals including parameter indicators (PIDs);
a PID identification module configured and arranged to use the data acquired by the data acquisition module to identify at least one PID that characterizes vehicle operation; and
a feedback module configured and arranged togenerate data that characterizes vehicle operation based upon the at least one PID and the acquired data, bypopulating at least one of an array and a matrix with the at least one PID, andusing the at least one of the array and matrix together with a model of the operation of the vehicle indicative of driver input-based safety risk characteristics, matching operation of the vehicle as characterized by the at least one PID with the model, anddetermine a driver input characteristic of the vehicle being driven based upon the data that characterizes vehicle operation.

Abstract
Apparatuses, systems and methods are implemented for characterizing one or more driver inputs. As may be relevant to one or more embodiments herein, particular aspects are directed to determining a driver input characteristic and using the determined input characteristic to assess a risk metric to the driver. In some implementations, the driver input characteristic is determined based upon a prediction of one or more of actual fuel used and torque. In some implementations, the prediction is determined in real-time and may be transmitted to a remote terminal for storage and/or analysis. The data for the prediction is obtained from a vehicle diagnostic system, and is used to determine (e.g., predict and/or infer) information as presented by other vehicle systems to the vehicle diagnostic system, without necessarily communicating directly with the respective other vehicle systems. In various implementations, the driver risk characteristic is used for assessing an insurance-based risk metric.
