aftermarket Self-Driving (steering too!) $1000 system from Comma.ai

Go for it. Report back.

 

See this thread: My Prius Prime Drives Itself | PriusChat

Though I still take serious issue with any true "self driving" claims at this time. The design, testing, and certification of systems reliable enough for general consumer use just aren't here yet. Misuse of existing driver assist features has already led to self fatalities. If or when such misuse leads to collateral fatalities, on systems not already demonstrated or certified as safer then average human drivers (about 1 death per 100,000,000 vehicle miles traveled), the misusers should face full liability, potentially even vehicular homicide charges.

 

I don't share that confidence. You must compare against equivalent new cars without those assist features too, or with such features turned off.

Full self-driving is a really tough analytical and computational problem, far beyond what we are accustomed to seeing in other applications.

 

This system has only two cameras.

Tesla has eight cameras (covering a complete 360° around the car), one forward-facing radar, and twelve sonars (also covering a complete 360°) according to Wikipedia. The computing platform is also far more sophisticated.

 

2020 Prime is supported. I'm using the first gen on my limited and it works great. The comma 2 has an IR camera so it can see you in the dark and a better cooling fan.

 

I thoroughly enjoy my comma setup. But IMO, its a stretch to compare it to Tesla. Comma is LKAS + ACC on steroids.

 

I've got a 2020 Prime and a Comma 1, and it works really well. However, I'm running a slightly modified fork to give smoother steering. The 2019 and 2020 Primes have TSS-1 like the older 2018 and 2017, but they have an upgraded steering sensor. The better steering sensor is important to prevent ping-pong effects (where the car overcompensates back and forth due to poor precision or feedback delay).

The main OpenPilot code doesn't take advantage of the upgraded steering sensor, but several forks do. Hopefully, Comma.ai will accept the pull request to incorporate the new sensor so 2019 and 2020 prime owners won't have to run a fork to get smoother steering.

 

What's a "fork" in this context?

 

Forked or diverging software paths?

 

A "fork" is terminology used in some source control software, like Git. OpenPilot is open source software hosted on GitHub, so anyone can easily copy the code and publish their own version with minor or major tweaks. The code has diverged from the original, so it has become a fork.

GitHub, and the underlying source control software git, makes it easy to merge new changes back in, so it's pretty easy to make a fork with your specific code changes, yet always keep it updated with the original software so you continue to get updates and improvements.

 

My mind was thinking hardware. Tnx.

 

I have the Comma 2 on my 2018 Prius Prime Advanced and it gives me 98% of what I want. New option called the Smart DSU will be released soon to make it even more desirable.

Took me 20 minutes to install.

Very Little Ping Ponging between the lines.

 

2018 Prius Prime Premium with comma 2 & Openpilot

 

This thing is a game changer for people like me who drive 150 miles or more a day. If buying a Prius, note that 2021 and newer will be the best for OP, 2019 to 2020 will need an SDSU for optimal experience, 2018 and older will require SDSU and zss for the best experience.

 

It doesn't yet do lights and stop signs, but will soon. It doesn't obstruct view of the road because it's mounted high. Works great in traffic, in cities, with or without lane lines. It just makes driving chill.

 

Don't let your expectations get too far ahead of the actual current technology.
