Tesla to improve parking chimes with directional sound

September 3, 2021

I'm sure I've said this before, but one of the amazing things about Teslas is that just about every item in the car is run through a software layer. For example, instead of the ultrasonic sensors being wired directly to the car's audio system to produce a tone when an object is in close proximity , the sensors are plugged up to a hub or motherboard, which then is completely software controlled. One of the many inputs are the ultrasonic sensors, and outputs are individual speakers, display, turn signals, headlights, ambient lights etc.

Tesla to improve parking chimes

This gives Tesla a great amount of flexibility. Nothing is set in stone. If Tesla wanted, they could make your ambient lights become brighter the closer an object was to the ultrasonic sensors. In fact, this is what gives Tesla the ability to let out a fart noise every time you use your turn signals in Tesla's Emissions Testing Mode.

We're now hearing that Elon agrees that they can do a better job with parking chimes. Currently Tesla displays a nice visualization in the car when an object is close to the ultrasonic sensors. The car will display an arc around the area of the car that the object is close to. The color of the arc is dependent on the distance of the object. The arc will change from gray to orange and red, all in a very fluid way. The vehicle will even display the distance of the object in inches or centimeters. The visualizations are great.

What's not so great, or rather is more on par with what other vehicles provide are the chimes that the car makes when encountering an object. The car produces slightly annoying chimes, akin to unfastened seat belt sounds when coming close to an object. The sound is roughly the same volume until you get very close.

Someone on Twitter suggested that Tesla improve the proximity sensors chimes to better match the great visualization Tesla already provides. They suggested that Tesla project the sound directionally based on the location of the object. They also mentioned that the volume should be an indicator for the distance of the object and the sound should be something other than chimes.

It's a great suggestion that has been suggested before, but Elon Musk actually responded to this particular suggestion. Elon either more strongly agrees with this suggestion now, or Tesla is or will be looking into this feature in the future.

Tesla has the ability to control each of the speakers in the car individually, so it would actually be amazing if Tesla could decode surround sound directly in the car. Tesla would then be able to encode sounds in a surround sound format and directional sound in the car.

Good point, agreed.

This could be used for a variety of features where directional sound is advantageous such as the parking chimes, turn signals, emergency braking and even the ability to watch Netflix and other streaming services in surround sound. After all, you already have a surround sound setup in your car, all we need is the software.

Tesla Vehicles Spotted With LiDAR: What Do They Use It For?

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.

However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.

What is LiDAR?

LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.

Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.

While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.

Why Does Tesla Use LiDAR?

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.

Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.

Tesla’s vision-only system has been seen to be extremely accurate, with Vision-only Autopark being able to park in even narrower and tighter spaces faster than the previous version that relied on ultrasonic sensors.

We’ll likely continue to see Tesla purchase LiDAR systems, as well as use them for validation well into the future.

Tesla's Upcoming Robotaxi Event in August Delayed, According to Bloomberg

In a report from Bloomberg, it is claimed that Tesla will be delaying its much-anticipated 8/8 Robotaxi event by two months to October 2024.

While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.

Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.

Why the Delay?

The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.

If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.

Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.

A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.

Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?

While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.

Is the Delay Accurate?

We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.

Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
