Abstract: An on-vehicle device for a driver monitoring system can be configured to be isolated from the vehicle bus while connected to the vehicle's OBD port. In a fully-isolated mode, the device only receives power and ground from the vehicle's OBD port and there is no other communication sent or received from the vehicle bus. In a passive mode, the device can obtain some information from the vehicle bus but does not request any information on the vehicle bus. The device may be undetectable on the vehicle bus. Optionally, the device receives commands via a communication interface to be switched among the three modes: fully active mode, fully isolated mode and passive mode. The commands may come from a server and may be communicated over the internet or over a cell network to a communication module on the device.

Abstract: A driver assessment system includes at least one vehicle sensor on a vehicle gathering vehicle dynamics information. At least one occupant sensor gathers driver information. The at least one occupant sensor may be a wearable device or subdermal device on the driver. At least one computer receives the vehicle dynamics information and the driver information to determine a driver readiness.

Abstract: An opportunistic calibration method continuously monitors a smartphone orientation and compensates for its variation, as necessary. The method relies on the probabilistic fusion of built-in sensors; in particular, the GPS, accelerometer, gyroscope, and magnetometer. The calibration method may utilize a state-machine approach along with an orientation stability detection algorithm to keep track of the smartphone orientation over time and to coordinate the calibration process in an opportunistic manner. An orientation calibration method may rely mainly on the probabilistic fusion of GPS and magnetometer sensory data.

Abstract: A vehicle monitoring system includes an accelerometer installed in the vehicle in an unknown orientation. The system infers the orientation of the accelerometer in the vehicle from the acceleration signals. The proposed method detects and corrects the orientation in two steps. In the first step, the gravity vector is used to estimate the orientation in the vertical plane. Then, based on the acceleration data collected during the vehicle movement, the heading of the vehicle is estimated and the orientation within the horizontal plane is corrected.

Abstract: A telematics system provides a platform for generating coaching tips, feedback, and simple indices based on driving behavior, historical information, heursistics and expert knowledge. The coaching tips are displayed on the policyholder portal and text describing the tips is completely configurable by an administrator on the server for the application. Furthermore, both ‘driving behavior’ and ‘environmentally friendly (green) driving’ tips can be supported.

Abstract: An in vehicle appliance gathers data from various sensors mounted within the vehicle, stores that data and generates summaries of that data for transmission through a wireless network. The data summaries reduce the length of the transmission over a wireless network while providing sufficient data to characterize vehicle operations without excessive transmission length, cost and use of available bandwidth.
