Increased Priority

If you follow my social media, than you might have noticed i’ve been doing nothing for the past week or so. Being a typical student, school took #1 priority as exams have been looming. Apologies for the speed at which this is being written. Exams finished today, specifically one hour ago. Therefore Carspotter is #1 on the list. Things to expect:

  • Two or 3 awesome films
  • Some apps for macOS(long story, will make a full article on it).
  • Tons of cool wallpapers and screensavers.
  • Lots of new content
  • Some cool things, fun stuff added to the site
  • More blog posts!

Thanks!

Close Call

Yesterday evening, returning from an unknown location, driving on an unknown highway, the four lane highway had two exits – each taking up two lanes. Now, from experience, if you take the wrong exit, it will take you 20 minutes to get back to unknown location A. Naturally, i’d rather take the right (as in correct) exit. But, i had a problem. Car A and car B. With car A being in front of us, and car B being in the lane to the right. I had to get over to lane 3 in record time to take my exit. Luckily, Mr. Musk planned for this, and included a 1 second merge time with our car at no extra charge. Pedal down, turn signal on, swerve. The car decided it would crash and tried to activate Collision Avoidance (hence the frantic beeping), luckily, it didn’t take evasive maneuvers. Alright, into lane 2. Now we have an even bigger problem. To our right, a GT350R. Obviously, this was great to get photos of, but he wanted to take the lane 1&2 exit, and we wanted to take the lane 3&4 exit. And the divider was nearing closer. The Mustang popped the clutch in and revved it to let us know he was going for it. Brakes for us, then. Coming within two feet of our car, the GT350 swerved over the white lines and into his exit while we did the same in the opposite direction. An unknown voice (not me) can be heard saying “Someone had to brake first” nearer the end of the clip.

Website troubles

Some of you may have noticed that the forum is completely gone. I will not be making a new one as some hackers targeted the forum and posted lots of.. Things. As of today, i’ve deleted the entire forum and it’s data. Apologies to those with legit accounts and anyone who visited the forum since May 7th.

Normal Service has been resumed, like i said above, the Forum section of the site is gone entirely and will not return.

Updates to Tapp – macOS app to control Model S and X

So, a little while ago, i updated Tapp to 1.3 – I did minor stabilization and added some new features. With this next update, i’m skipping right to 1.5, then 2.0. This is because as some of you may know, API’s only have a set amount of commands and GETs one can send/request. As of today, i’ve used all of the above. So, at this point, i’m going to work out as many bugs as possible and release Tapp 1.5 tomorrow or the day after. Any suggestions before 1.5? For 2.0? Comment!

Testing Tesla’s Collision Avoidance

As some of you might know, i’ve been attempting to hit a pedestrian with a Model S on AutoPilot for a long time now. Over the many tests i’ve done, i’ve found some pretty odd results – find them below. I would like to thank Elon Musk and Tesla Motors for their outstanding implementation of Collision Avoidance, Traffic Aware Cruise Control(TACC), AutoPilot(AP) and, of course, Automatic Emergency Braking(AEB). My main goal was to have a pedestrian force the vehicle to initiate an AEB event without driver intervention and thanks to Tesla’s immaculate attention to even hidden details, this was accomplished. I also wanted to contribute useful data to help with the evolution of Tesla’s safety systems.

Over the course of this post, i will refer to the car in question as ‘Model S’, not ‘The Tesla Model S’ – I could go into depth as to why, but i won’t bore you. I will also use terms such as TACC, AP and AEB. These terms are declared above. Also, UI is short for User Interface – Basically the driver’s display.

Test #1

  • AutoPilot slows down almost to a standstill, but shows no indication of any object in it’s way. My thoughts are that the radar and camera both saw the pedestrian, but Model S didn’t know what it should display the pedestrian as. As it’s only programmed to show a pedestrian in the event of a Collision Avoidance instance. After the pedestrian moved out of Model S’s way, the car proceeded to accelerate and then, to park behind a parked car. What’s interesting is that Model S wasn’t driving towards the parked car, but rather beside it. I’m guessing that when the lane markers disappeared, Model S continued straight, on it’s original path. Then, when the radar and camera picked up the parked car, Model S must have thought the roadway had taken a corner, and swerved to get back into it’s lane – behind that parked car. What is even more interesting is the fact that when Model S pulled behind the parked car, it displayed the car as being pulled over. In the video, there is a gradient change in colour about halfway through the parked car on the UI. This seems to indicate the side of the road. Interesting.

Test #2

  • This time, AutoPilot was not enabled. It’s hard to say if Collision Avoidance actually did activate, but i’d put my money on it. The classic warning chime played over the sound system, but nothing happened as far as the UI. It appears that Model S detected the pedestrian as an object but figured out that the object was going to pose a threat to the vehicle, unlike a plastic bag, for instance. I would suggest that Tesla incorporate an unidentified object image for the UI, for instances like these. I find this extremely interesting because many times, I’ve thrown cardboard pedestrians, tinfoil walls and other assorted objects into the car’s path and every single time, Model S proceeded to demolish the object without warning. At this point my theory is that the camera picked up the object fine, but the radar either sees through the object or finds the density of the cardboard and finds that it’s not a real pedestrian or vehicle.
