News hardware Electric car: heading for a revolution in autonomous driving at Tesla?
It’s been in Tesla’s and Elon Musk’s little papers for a while now, and now it all seems well done. The autonomous driving of the brand’s vehicles will be fully reviewed. Radars, ultrasonic sensors or camera? The company has therefore made its choice.
Tesla: radars, ultrasonic sensors or cameras, what to choose?
last April, Tesla had confirmed that its transition to Tesla Vision would phase out radars from its Tesla Model 3 and Model Y sold in the US. Recently, we learned that the Model S and X would also follow the same direction. This decision enabled the manufacturer to ensure that Tesla Vision will be supported by software development, eight external cameras and twelve ultrasonic sensors.
But the situation seems to have changed again. We’re six months later and a new victim has just been identified: ultrasonic sensors. It’s throughan update on the Tesla Vision support pagethat we learned that the new models coming to the market will be deprived of ultrasonic sensors – the 12 located at the level of the bumper.
Currently, the first affected will again be the Tesla Model 3 and Y. Then it will be the turn of the Model S and X to undergo the box changes – The US will be the first to receive these changes. It must therefore be understood that the manufacturer’s autonomous driving system will now only work with the help of the cameras.
What consequences for Tesla users
As you can imagine, the first customers who receive vehicles without ultrasonic sensors will not be able to enjoyfor a certain time, many functions. Here they are :
- Park Assist: warns you of nearby objects when the vehicle is traveling less than 8 km/h.
- Car parking: automatically maneuvers into parallel or perpendicular parking spaces.
- Auto Exit: Manually move your vehicle forward or backward through the Tesla app.
- Smart Auto Exit: directs your vehicle to you or a location of your choice via the Tesla app.
The company takes care of that “in the near future, and once these features have reached the same performance levels as current vehicles, they will be restored via a series of over-the-air software updates”. Tesla also adds that it currently has no plans to remove ultrasonic sensor functionality from its existing fleet.
Autopilot Tesla: a change for better or worse?
With all these changes, a question may arise: what about security? Although the combined use of radars, sensors and cameras seems to be the most suitable for autonomous driving, certain special conditions must still be taken into account. E.g, ultrasonic sensors are very useful at low speeds – like in parking lots – but their removal is still less effective than speed cameras.
The combination of speed cameras and cameras is, according to the Insurance Institute for Highway Safety (= Insurance Institute for Road Safety), the best way to avoid accidents (of all types), as cameras are more effective during the day and radars at night. With this new decision, Tesla specifies that its autonomous driving systems will therefore bet everything on the use of cameras and software development.
This choice undoubtedly also has a small financial component, as the overall commitment to the software enables, among other things, a reduction in production costs.. Take effect, without radars or ultrasonic sensors, Tesla should reduce the amount of chips in its vehicles a bit in a particularly difficult time for the car industry – and not only. To find out if Elon Musk and his team have made the right choice, we just have to wait for the first vehicles carrying the modifications to be put into circulation. related to Tesla Vision in the US.
