Abstract: A data logging unit configured for installation in a hybrid vehicle communicates with a user device configured to receive data from the data logging unit and to display selected portions of the data to a user for identification of potential vehicle faults associated with vehicle events reported by the vehicle's driver. The data logging unit has a data logger which communicates with hybrid drive system and other vehicle components to receive hybrid drive system data, and with a vehicle position sensor which detects location to receive vehicle location data. A data log processing module correlates location data with the corresponding vehicle data, and creates a correlated log of drive system data and associated vehicle location information, to allow identification of vehicle data within an event window based on vehicle location at the time of a reported event. Accordingly, a user may make a geographical request and the system will report vehicle data corresponding to the geographical request.

Abstract: A vehicle monitoring system and method has a vehicle unit which is mounted in each vehicle and a remote monitoring and diagnostic server or system which receives periodic status information in messages from the vehicle units of all active vehicles and displays the data in a user interface on one or more user devices. The vehicle unit is configured to send periodic first messages containing a first, partial set of vehicle operation status information and periodic second messages containing a second, larger set of status information, and may be switched to send second messages at faster time intervals depending on various conditions. The user interface displays at least part of the second set of vehicle information for a selected vehicle while displaying at least part of the first set of vehicle information for at least some active vehicles sending messages to the remote server.
