Announcements from the Tesla Q2 2018 results conference call

We don’t cover Tesla’s stock, financial results, or other stuff that isn’t their product but this time during the Q2 call, they made really cool product announcements:

  • v9 would include on-ramp off-ramp AP with automatic lane change when possible
  • Hardware 3 will be introduced next year. According to the announcement, the new hardware is a chip designed in-house. This chip is designed explicitly for neural network processing. There are drop-in replacements for the Model S, Model X, and Model 3. According to Elon, the current Nvidia hardware can process 200fps while this new one can process over 2000fps.
  • The coast-to-coast trip on AP won’t happen soon. The AP team is focused on «safety features» like recognizing stop signs and traffic lights in a super reliable way. They don’t want to distract the team or do it with a predefined hardcoded route, so it’s going to have to wait.

According to him, it’s probably going to be a degraded experience compared to the HW2.5 to HW3 retrofit, and looking at the changes in the latest firmware versions, it seems they don’t plan on changing the radar or the steering rack.

Tesla turned on redundancy in HW3

According to Greentheonly, in the version 2019.40.50.1, the B node in the HW3 board starts the full copy of the Autopilot software. This is important because if one node crashes, the car can immediately start using the other one for redundancy.
