OPERATIONS The VHM-HD automatically operates while installed in a vehicle. It logs vehicle trip data, fleet management data, GPS location and diagnostic messages for subsequent upload to the network via local wireless base station(s). The device can store up to typically 2,000 trip records between uploads. 1. Vehicle arrives back at base station location and automatically communicates with wireless Access Point (AP). 2. The VHM-HD uploads its fleet management records to the AP base station. Support for a virtual AP app on a smartphone or tablet is also available. 3. The AP stores and forwards the VHM-HD records to Yashu s Web Server Storage and/or 3rd party management application(s).

VEHICLE USAGE DATA LOGGING The VHM-HD records a variety of different indicators during the vehicle s daily use. Various parameters track and manage vehicle health, performance, fuel use and driver behavior. Some of these parameters are tracked only at upload time, but the majority are tracked every second on a trip-by-trip basis. Reference the following subset of typical parameters which can be logged. DATA DESCRIPTION ENGINE DATA VIN Diagnostic Readiness (DM5) Emissions System Monitors Status Vehicle Identification Number Status of vehicle emissions monitors includes: misfire, fuel system, comprehensive component, evaporative system, oxygen sensor, oxygen sensor heater, catalyst, heated catalyst, AC system refrigerant, secondary air system, EGR system Diagnostic Message (DM) Status DM Event Log Lists DM1 / DM12 diagnostic messages with associated Suspect Parameter Message (SPN) and Failure Mode Identifier (FMI) w/ Occurrence Count (OC) Date / time stamp for any DM events can capture and track intermittent DM codes Average Engine Coolant Temperature Max Engine Coolant temperature Fuel Rate / Consumption Average engine coolant temperature per trip Maximum engine coolant temperature per trip Reported fuel rate with subsequent integrated fuel consumption per trip UTILIZATION Trip Duration Trip Start (UTC) Trip Distance Driver ID Engine Idle Time Duration Duration of the trip Date/time of trip start in Coordinated Universal Time Distance travelled during the trip Use of the Yashu Driver-ID badge identifies the individual driver per trip Duration of engine idling to track excessive idling time on vehicles FUEL EFFICIENCY Fuel Efficiency (Moving) Fuel Efficiency (Idling) Total Fuel Efficiency Total Fuel Used Total Idling Fuel Used GPS LOCATION AND EVENTS Latitude / Longitude / Altitude Location Tracking Location of Threshold Exceed Events Calculated fuel efficiency of the vehicle per trip while it is moving Calculated fuel efficiency of the vehicle per trip while it is idling Composite fuel efficiency per trip includes both moving and idling time Total fuel consumed during the trip Total fuel consumed while idling per trip proprietary dead reckoning algorithms fill in any location gaps during loss of GPS signal in urban or mountainous areas. The integrated MEMS accelerometer / gyroscope and J1939 vehicle kinematic parameters are fused together within advanced Kalman estimation routines. Integrated GPS receiver supports 2 minute (default) breadcrumbs trail from multi-constellation satellites (GPS / QZSS, GLONASS and BeiDou). Vehicle location is logged during any event that exceeds a configurable threshold. Supported events include speed, idling and acceleration / deceleration. 2013-2015 Page 3 of 5

Provides an accurate indication of the time a vehicle has experienced DM event. Date / time / location stamped event listing of every idle event greater than 1 sec. Can be used to track excessive idle time by drivers. Also supports distracted driving programs to differentiate moving time vs stopped time during any trip. RAW SPN PARAMETER DATA LOGGING While the previous Vehicle Usage Data generates memory efficient compressed data structures, it may be desirable to simultaneously log raw SPN information for closer inspection of vehicle operation. Future VHM-HD support will be provided to perform isochronous sampling of a configurable set of SPNs. User entry of the desired SPN s arbitration ID, data size, scaling and bias is possible via the intuitive Yashu Device Utility Software GUIs. Reference the following logging script example showing all configurable field entries for an eight SPN data log. Exposing the various fields (ArbID, Src Address, Byte, etc..) allows the user the capability for configuring any proprietary PGNs and/or SPNs. This allows for OEM specific data gathering beyond the SAE J1939 predefined parameter set. Additional support also includes auxiliary I/O units and unique sensor logging equipment conforming to the SAE J1939 protocol standard. 2013-2015 Page 4 of 5
RAW SPN PARAMETER DATA LOGGING (CONTINUED) RAW SPN PARAMETER DATA VIEWING UTILITY Although Yashu Web Server allows data import of the logged raw SPN information from the VHM-HD device, the Yashu Device Utility Software also provides a basic Data GUI for general inspection of the information in graphical format. Further subsequent analysis of the data can be performed through the exporting capabilities of Yashu Web Server.
