Teledriving / Remote Driving

Soliton’s Technology for Teledriving Solutions

What is Teledriving?

Teledriving is a relatively new concept of remote driving. Not to be confused with the self-driving car, Teledriving allows vehicles to be “driverless” with the vehicle been driven from a remote teleoperation center by a “teledriver”. A human remains in full control of its operation albeit remotely. 

It is expected to gain certification to operate on the public streets in the not-too-distant future where it can be used for applications such as affordable door-to-door taxi services, or where an autonomous vehicle needs to “phone-home” as its current programming cannot resolve a unique situation and needs assistance to continue. 

The technology behind teledriving

Soliton has been actively involved in developing highly reliable elements of the solution that is core to delivering a complete remote driving solution. The teledriver, who sits in a mockup car console with its steering controls, looks at monitors around them that gives them the view from the car as if they are looking through the windscreen, mirrors and side windows. If the teledriver is to operate the car safely, then it’s imperative that the view they receive is in real-time. A delay of even a few hundred milliseconds could prove fatal, given the time it would take for the driver to pull out safely into traffic or to react to an emergency which could be too late.

Soliton’s unique Zao technology can provide live video streams from the car back to the teledriver in less than 100ms. It does this using bonded cellular connections and its own RASCOW2 technology.   By bonding together multiple 4G and 5G connections, it is possible to create multi-links with different cellular operators simultaneously for extreme reliability and high bandwidth. This is utilized for live streaming video back to the teleoperator.  As the Zao technology can provide two-way communication, it operates bi-directionally. In one direction from the car to the teledriver is the ultra-low latency live video, streaming from multiple cameras in or on the car, and the second is a secure IP network connection that sends the commands from the teledriver to control the car for real time operation.

Ultra-low latency of video transmission from a remote location back to the teleoperator is a key feature of Soliton’s technology. Other bonding systems typically have latencies of 1 to 2 seconds. Even over 4G, Soliton can uniquely have latencies of 65ms and below that includes both encoding and decoding. With 5G, this latency can be reduced further.

Soliton’s technology is being adopted by teledriving companies and automotive companies that are seeking to implement such reliable and low latency solutions.  Where video will become important for the aspect of car communication with infrastructure, it is important that the technology is cloud and MEC ready.

The Zao technology does not rely on expensive 360-degree lidar sensors, nor does it have the lidr requirement of collecting massive amounts of data and so making it less expensive and easier to implement.

What about other teleoperation applications?

The same principle of remote operation of vehicles can also be applied to other similar scenario’s such as remote control of cranes, diggers, forklift trucks and mine clearing equipment. Where there is a war zone or hazardous area that is unfit or dangerous to work, by utilizing the Zao ultra-low latency video streaming equipment, it is possible to take humans out of high-risk areas where equipment that would normally need a human operator. The machinery can be remotely controlled and driven from the safety of a teleoperation center that could be anywhere in the world.
