3. Current Method 1 x J1962 connector 16 pins
Vehicle interface hardware for every application

4. Upsides/Downsides Inexpensive to implement (<$7 @ 1M)
Backward compatibility to 1996
Hundreds of devices on the market in thousands of applications
Too many buses to put on J1962 connector
5+ CAN at various speeds
5+ ISO-K
J1850 PWM/VPW, SCI, BEAN, single-wire CAN
Conflicts between different OEM functions on same pin
Potential for poor equipment to interfere with vehicle operation
Inconsistent vehicle state
Minimal security

5. Pin Conflicts
Orange = signal conflict between vehicles

6. Concept Vehicle network gateway connecting to all busses
A variety of devices can access the vehicle
Consistent vehicle state data, especially for power control
Provide the same capability as the previous direct data bus access for diagnostics applications
Ensure vehicle network stability

7. Requirements Interface to multiple devices simultaneously
Security access levels
Basic read-only data
Full bus access
Prevent interference between devices
Cost minimized to OEMs and tool manufacturers
Implementation should be straightforward

8. Implementation USB Ethernet Ubiquitous Inexpensive High speed
Low latency
Requires one interface per port, not easily expandable
Depending upon USB profile, can be used with inexpensive microcontrollers
Power via USB, non-standard in this manner, maximum 5W
Ubiquitous
Inexpensive
High speed
Low latency on local network
Easily expansion using Ethernet hubs and switches
Can be used with inexpensive microcontrollers at lowered data rates
Power-over-Ethernet, maximum 25W

9. Benefits to Vehicle Manufacturers
Can use generic, low-cost radio hardware for OEM telematics
No expectation to provide an ‘app’ ecosystem or data connectivity to 3rd party functions
Equipment conflicts eliminated
Flashing and diagnostics all can be done with a standard computer if needed
Dealership can hook vehicle to diagnostics system easily via WiFi dongle

10. Vehicle 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.

11. Benefits to ETI Members
Consistent access to vehicle systems
Opportunity to supply vehicle gateways to OEMs
Could bring an era of better software-only scantools
BOM reduction for both low- and high-end devices
Relaxed device packaging constraints as expansion ports can be located in remote vehicle areas (trunk?)

12. Tool 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

13. Technical Details 4 Ethernet ports
One preferably located near the driver’s seat
Remainder located near rear of vehicle
Basic 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.

14. More Future Vehicles Would have Ethernet already
Could be directly connected to diagnostic ports as long as access APIs are preserved
Solid upgrade path

15. Backwards 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.
