1Future Vehicle Telematics Robert Vogt IVCEOIOSiX, LLC
2IOSiX, LLCFormed in 2005Focused on compact, cost- effective dataloggers, vehicle interfaces, and custom devicesExtensive hardware/software platformQuick turn-around IP leveragingFull automotive engineering capabilities to the vehicle subsystem levelExtensive protocol suiteSAE J1850 PWM/VPWISO /KWPISOSAE J1939 & J1708WiFi/Bluetooth/Zigbee/900MHzGSM/CDMA/SatelliteGPS/RTK-GPSDC/DC power conversion & control, Lithium battery IPUSB, microSD, FAT16/32Video/Audio capture & encoding
3Current Method 1 x J1962 connector 16 pins Vehicle interface hardware for every application
4Upsides/Downsides Inexpensive to implement (<$7 @ 1M) Backward compatibility to 1996Hundreds of devices on the market in thousands of applicationsToo many buses to put on J1962 connector5+ CAN at various speeds5+ ISO-KJ1850 PWM/VPW, SCI, BEAN, single-wire CANConflicts between different OEM functions on same pinPotential for poor equipment to interfere with vehicle operationInconsistent vehicle stateMinimal security
5Pin ConflictsOrange = signal conflict between vehicles
6Concept Vehicle network gateway connecting to all busses A variety of devices can access the vehicleConsistent vehicle state data, especially for power controlProvide the same capability as the previous direct data bus access for diagnostics applicationsEnsure vehicle network stability
7Requirements Interface to multiple devices simultaneously Security access levelsBasic read-only dataFull bus accessPrevent interference between devicesCost minimized to OEMs and tool manufacturersImplementation should be straightforward
8Implementation USB Ethernet Ubiquitous Inexpensive High speed Low latencyRequires one interface per port, not easily expandableDepending upon USB profile, can be used with inexpensive microcontrollersPower via USB, non-standard in this manner, maximum 5WUbiquitousInexpensiveHigh speedLow latency on local networkEasily expansion using Ethernet hubs and switchesCan be used with inexpensive microcontrollers at lowered data ratesPower-over-Ethernet, maximum 25W
9Benefits to Vehicle Manufacturers Can use generic, low-cost radio hardware for OEM telematicsNo expectation to provide an ‘app’ ecosystem or data connectivity to 3rd party functionsEquipment conflicts eliminatedFlashing and diagnostics all can be done with a standard computer if neededDealership can hook vehicle to diagnostics system easily via WiFi dongle
10Vehicle Manufacturer Costs Depending on vehicle bus configuration, a high volume solution can be reached in the sub-$20 range:$3 – Processor$2 – Ethernet transceiver$4 – 100 mbps Ethernet switch (4 ports)$4 – Vehicle bus transceivers$4 – Connectors$2 – Casing, Power, etc.
11Benefits to ETI Members Consistent access to vehicle systemsOpportunity to supply vehicle gateways to OEMsCould bring an era of better software-only scantoolsBOM reduction for both low- and high-end devicesRelaxed device packaging constraints as expansion ports can be located in remote vehicle areas (trunk?)
12Tool Manufacturer Costs -$4 transceivers-$3 cables and connectors+$2 Ethernet transceiver+$0.50 processor with Ethernet support (SPI?)Net savings of $4.50+ in high volumes
13Technical Details 4 Ethernet ports One preferably located near the driver’s seatRemainder located near rear of vehicleBasic API would cover vehicle speed, emissions data, odometer, brake switch, accelerometer data, fuel consumption, etc.Advanced API would provide encapsulated access to the vehicle data busses. Requests could be throttled as-needed to prevent interference with critical vehicle comms.
14More Future Vehicles Would have Ethernet already Could be directly connected to diagnostic ports as long as access APIs are preservedSolid upgrade path
15Backwards Compatibility There will be a need for existing vehicles to be retrofit with a small Vehicle Network Gateway to work with newer equipment.This could be one-size-fits-all or a different part by vehicle manufacturer and legacy data bus.There would be a strong opportunity for ETI members to supply these aftermarket components.
