Welcome to Tinkla!

In early 2018 I got involved with the Comma.ai OpenPilot project. The more I got involved, the deeper I wanted to integrate OpenPilot with my Tesla Model S for a better experience. Today, by just looking at the instrument cluster (IC) or the center instrument display (CID) you would not know if the car is equipped with the Tesla original AutoPilot (AP1) or with our version of OpenPilot for Tesla.

Quick Start

1. The Tesla Giraffe install guide will start your journey to driving with OpenPilot.
2. Plug your Comma.ai Panda into your Giraffe
3. Then make and install the EPAS Harness.
4. Install the EON in your windshield.
5. Then install the Tesla version of OP
6. Finally take your Tesla w/OP for a spin!
7. And if you want to have IC integration (root access not required), now you can with Tinkla Buddy

Out of the Box

Well, just few easy mods to your Tesla and OpenPilot does a fairly good job at lane keep assist (LKA) and introduces a limited adaptive cruise control (ACC) based on the OpenPilot vision radar and just regenerative (regen) braking. Also, the system has a built in lane departure warning (LDW). All you need is:

1. an EON, (not a comma two devkit)
2. a Panda,
3. a Tesla Giraffe,
4. and a fairly easy to make EPAS harness.

The cost for this complete setup is about $1,000 USD when getting all the components from Comma.ai and ebay (for the harness).

Map Integration

Comma.ai has brought map integration for longitudinal control (slowing down in turns for example) and there are plans to start bringing map info into lateral control as well to improve turning. Map integration is a key component for us too in order to improve the turning capabilities of the system.

0 - 18 MPH Upgrade

The "Out of the Box" setup is the basic install for your tesla and can control your acceleration above 18 MPH. The Pedal Interceptor is a small unit that gets connected between your accelerator pedal on your Model S and the Giraffe. While the stock cruise control on Tesla only works above 18 MPH, with the pedal we can control speed down to 1 MPH (though the regen brakes only work above 5 MPH). The benefit of the pedal is better (and smoother) adaptive cruise control over just the stock Tesla cruise control.

Tesla Radar Retrofit

With a few more wires and a harness (plus some eBay parts) you can add a Tesla Bosch radar to your pre-AP1 car. With full radar integration now available in OpenPilot, you get more accurate lead car detection which leads to a better ACC (still limited to regen braking). Also, if you have Instrument Cluster integration, now you can see 3 lanes full of cars on your IC.

If you want easy integration Tinkla Buddy is the way to go.

Stop-and-Go

The next hurdle for us is integration with iBooster brakes for full stop and go traffic. This will require replacement of the standard vacuum brakes on your pre-AP1 Model S to the iBooster system that Tesla used in the AP1 cars and beyond. This will be about $500-$800 in parts and some more involved mechanical work as you would need to flush your brakes and such. Also, root access is needed for this upgrade.

Parking Sensors

Finally, we will be integrating the AP1 style parking sensors into the OpenPilot code, allowing us to use the data from the 12 sensors to detect cars around us. This is one step we're hoping to start soon. Depending on where you source the sensors and harness, this alone can be somewhere between $500 and $1,500.

AP1 Integration

Once all this is done, we will be able to fully integrate with AP1 cars as well. With Tesla no longer paying any attention to the older Model S (the AP1 was based on the MobileEye platform that Tesla dumped in October 2016 and has received limited code updates ever since), the only option to get new features and functionality is by joining the OpenPilot group.
