Tesla software update 2019.40.50 full release notes, video demos, and details.

Tesla rolls out cool new features and games in the 2019.40.50 grand software update

Tesla has finally started rolling out this year’s last major software update, the firmware version 2019.40.50 — this update brings cool new features and two new video games to the table, now Tesla Autopilot is more capable in detecting surrounding objects and stop signs.

According to TeslaFi data collection, the most stable and widely released subversion of this update is the 2019.40.50.1 and most of the Tesla owners are able to download the update before Christmas.

The first set of new features like the Adjacent Lane Speeds, Autosteer Stop Sign Warning, and Automatic Wiper Improvements was released in the 2019.40.2 update a couple of weeks ago which is the prequel to the current more extensive update.

Full Self-Driving Preview

As we can see that the Tesla CEO Elon Musk gave a teaser of the upcoming features including a sneak preview of the full self-driving (FSD) last week, several Tesla owners are reporting drastic improvements in Autopilot/Autosteer performance.

The new and improved driving visualizations can now even show objects like garbage cans on the side of the road, and as we can see in the screenshot above, the car can even see the STOP mark on the road in addition to the sign on the roadside.

Only Teslas with Hardware 3.0 (produced after April 2019) currently have the FSD preview, according to Elon Musk, the free HW3 supercomputer retrofit should start happening Q1′ 2020 — YouTuber Tesla Raj’s Tesla Model 3 has the FSD sneak preview with the new visualizations he has featured in the following video.

The 2019.40.50 release notes provide the details and how to unlock the new FSD visualizations from your center touchscreen interface:

Driving Visualization Improvements

The driving visualization can now display additional objects which include stoplights, stop signs and select road markings. The stop sign and stop light visualizations are not a substitute for an attentive driver and will not stop the car. To see these additional objects in your driving visualization, tap Controls > Autopilot > Full Self-Driving Visualization preview.

Voice Commands

This is the most cool feature of the 2019.40.50 Tesla software update as we can see in the following Tesla release notes and video by a Tesla Model 3 owner — the newly rebuilt ability of Tesla vehicles to take voice commands and act upon them brings further safety to the cars as the driver does not need to be distracted to perform routine tasks.

With the new voice commands Teslas can open the glovebox, enable/disable Sentry Mode, listen and respond to SMS/text messages, search for music/podcasts, navigate to nearby Supercharger stations, and a lot more — the icing on the cake is that the commands which the car does not currently understand, those commands are sent to Tesla neural net to deepen the fleet’s AI learning.

Voice commands have been rebuilt to understand natural language. For this initial release, we focused on commands that minimize having to touch the screen so you can keep your eyes on the road. A few areas and examples of what you can say are:

  • Climate: “Set the temperature to 70”, “Turn on the passenger seat heater”
  • Vehicle: “Adjust my right mirror”, “Open the glovebox”
  • Navigation: “Let’s go to work”, “Where are the nearby supercharging stations”
  • Media: “Play the Beatles”, “Search for Joe Rogan podcast”,
  • Communication: “Call Davis Lewis”, “Send a text message to Evan”
  • Other: “Show me the rear camera”, “Open Autopilot settings”

Anonymized voice commands will be captured to further train and improve the system in future software updates.

Reading and responding to text messages without taking your hands off the steering wheel is now a breeze in Tesla cars as with just pressing the right scroll wheel the Tesla drivers can now listen and reply to messages with voice commands, the car’s AI converts the voice into text and replies back.

Release notes and demo video:

You can now read and respond to text messages using your right scroll wheel button. When a new message is received press the right scroll wheel button to have your text message read out loud and press again to respond by speaking out loud. You will also be able to view messages as they come in via the “Cards” section of the touchscreen.

Once enabled, you can also choose to play a chime whenever a new text message is received by enabling “Chime on New Message”.

Note: Notifications need to be enabled on your device from the phone’s Bluetooth settings to send and receive text messages. Due to the limitations of Bluetooth support from your device, you will not be able to send group messages. As usual, Bluetooth behavior may depend on the make and model of your device.

Camp Mode

The ‘Keep Climate ON‘ function has now evolved into ‘Camp Mode’, previously this climate control feature was limited to cooling/heating the cabin to the desired temperature but now it includes playing music and interior lighting as well.
