Renault SYMBIOZ; A level 4 Autonomous Car

Renault recently unveiled a new concept car called the Renault SYMBIOZ, this concept is meant be a marker of a large leap in the industry of autonomous driving, with what they call level 4 autonomous what this means is “The driving mode-specific performance by an automated driving system of all aspects of the dynamic driving task even if a human driver does not respond appropriately to a request to intervene”, or in simpler terms the driver doesn’t need to be paying attention to the road or have hands on the steering wheel.

For those interested the levels of automation are defined as such:

  • Level 0
    • The full-time performance by the human driver of all aspects of the dynamic driving task, even when “enhanced by warning or intervention systems”
  • Level 1
    • The driving mode-specific execution by a driver assistance system of “either steering or acceleration/deceleration” using information about the driving environment and with the expectation that the human driver performs all remaining aspects of the dynamic driving task
  • Level 2
    • The driving mode-specific execution by one or more driver assistance systems of both steering and acceleration/deceleration using information about the driving environment and with the expectation that the human driver performs all remaining aspects of the dynamic driving task
  • Level 3
    • The driving mode-specific performance by an automated driving system of all aspects of the dynamic driving task with the expectation that the human driver will respond appropriately to a request to intervene
  • Level 4
    • The driving mode-specific performance by an automated driving system of all aspects of the dynamic driving task even if a human driver does not respond appropriately to a request to intervene
  • Level 5
    • The driving mode-specific performance by an automated driving system of all aspects of the dynamic driving task under all roadway and environmental conditions that can be managed by a human driver

So far the Renault SYMBIOZ is the first car concept to attain level 4 autonomy, this is 2 levels above the Tesla cars which are widely considered to be the forerunners in this aspect of the industry. Renault have said that they believe this concept represents what all cars will be like by 2030, so we should check back in over a decade to see whether they were correct or not.

As for autonomous cars, for now I think many of us would rather keep our hands on the wheel, you know “just in case…”.
