According to Tesla, forward radar, a forward-looking camera, 12 long-range ultrasonic sensors around the car, and a high-precision digitally-controlled electric assist braking system, are to be used by the new Version 7.0 software release to allow the automated driving capabilities.
"While truly driverless cars are still a few years away, Tesla Autopilot functions like the systems that airplane pilots use when conditions are clear," the company explained in a press release on Wednesday.
On Wednesday, Tesla sought to reassure any Model S owners nervy at the thought of giving over control of their car to a computer.
"The driver is still responsible for, and ultimately in control of, the car. What's more, you always have intuitive access to the information your car is using to inform its actions."
Drivers who want to upgrade to autopilot will have to pay $3,000 for the privilege of the built-in chauffeur, which is able to steer the car within a lane of traffic, changes lanes and manage speed. In addition, autopilot is able to scan for a parking space, alert the driver when one is available, and parallel park on command.
