Abstract

A vehicle system comprises a gateway controller, configured to collect real-time vehicle data from an electronic control unit (ECU); responsive to receiving a start token from a testing device, send the real-time vehicle data to the testing device via at least two connections of different types, each connection having a predetermined bandwidth; and inverse multiplex the real-time vehicle data into separate real-time data streams that match the predetermined bandwidth of each connection.

First claim

What is claimed is:

1. A vehicle system, comprising:
a wired transceiver configured to establish a wired connection having a first bandwidth to a testing device;
a wireless transceiver configured to establish a wireless connection having a second bandwidth to the testing device; and
a gateway controller, configured to
collect real-time vehicle data from a first electronic control unit (ECU) via a first vehicle network and from a second ECU via a second vehicle network different from the first vehicle network,
responsive to receiving a start token from a testing device via one of the wired connection or wireless connection requesting for the real-time vehicle data from the first and second ECUs, inverse multiplex the real-time vehicle data into a first stream for the wired connection based on the first bandwidth and a second stream for the wireless connection based on the second bandwidth, and
send, to the testing device, the first stream via the wired connection and the second stream via the wireless connection.

2. The vehicle system of claim 1 , wherein the gateway controller includes a real-time vehicle data logger, programmed to collect, serialize, multiplex, time-stamp, and buffer the real-time vehicle data.

3. The vehicle system of claim 2 , wherein the gateway controller includes a streaming server programmed to convert the real-time vehicle data from the real-time vehicle data logger into first and second streams.

4. The vehicle system of claim 1 , wherein the wireless connection includes at least one of the following types: WiFi; Bluetooth; cellular; near-field communication (NFC); radio-frequency identification (RFID); or dedicated short range communications (DSRC).

5. The vehicle system of claim 1 , wherein the wired connection includes at least one of the following types: ethernet; on-board diagnostics (OBD); or universal serial bus (USB).

6. The vehicle system of claim 1 , wherein the gateway controller is further configured to authenticate the start token from the testing device.

7. The vehicle system of claim 1 , wherein the gateway controller is further configured to receive and authenticate a stop token from the testing device, and responsive to a successful authentication stop sending the first and second streams.

8. A vehicle testing device, comprising:
a wired transceiver configured to establish a wired connection having a first bandwidth to a vehicle;
a wireless transceiver configured to establish a wireless connection having a second bandwidth to the vehicle; and
a processor, configured to
send a start token to the vehicle indicative an intent to receive real-time vehicle data from plurality of ECUs,
receive a first stream via the wired connection, the first stream being corresponding to the first bandwidth and representative of a first part of the real-time vehicle data,
receive a second stream via the wireless connection, the second stream being corresponding to the second bandwidth and representative of a second part of the real-time vehicle data,
multiplex the first stream and the second stream to obtain the real-time vehicle data.

9. The vehicle testing device of claim 8 , wherein the processor is further configured to multiplex the first and second streams into a single transmission control protocol/internet protocol (TCP/IP) data stream represent of the real-time vehicle data, using a binary serialization method.

10. The vehicle testing device of claim 8 , wherein the wireless connection includes at least one of the following types: WiFi; Bluetooth; cellular; near-field communication (NFC); radio-frequency identification (RFID); or dedicated short range communications (DSRC).

11. The vehicle testing device of claim 8 , wherein the wired connection includes at least one of the following types: ethernet; an on-board diagnostics (OBD); or universal serial bus (USB).

12. A method for a vehicle to transmit vehicle data to a testing device, comprising:
establishing a first connection having a first bandwidth to the testing device;
establish a second connection having a second bandwidth to the testing device;
collecting real-time vehicle data from a first electronic control unit (ECU) via a first vehicle network and from a second ECU via a second vehicle network different from the first vehicle network; and
responsive to receiving a start token from a testing device indicative of an intent to receive the real-time vehicle data from the first and second ECUs, inverse multiplexing the real-time vehicle data into a first stream for the first connection based on the first bandwidth and a second stream for the second connection based on the second bandwidth,
sending, to the testing device, the first stream via the first connection and the second stream via the second connection.

13. The method of claim 12 , wherein the first connection is a wireless connection of at least one of the following types: WiFi; Bluetooth; cellular; near-field communication (NFC); radio-frequency identification (RFID); or dedicated short range communications (DSRC).

14. The method of claim 12 , wherein the second connection is a wired connection of at least one of the following types: ethernet; on-board diagnostics (OBD); or universal serial bus (USB).
