Tesla announces moving away from ultrasonic sensors in favor of ‘Tesla Vision’
Tesla announced today that it is moving away from using ultrasonic sensors in its suite of Autopilot sensors in favor of its camera-only “Tesla Vision” system.
Last year, Tesla announced the transition to its “Tesla Vision” Autopilot without radar. The automaker would start producing vehicles without a front-facing radar.
Originally, the suite of Autopilot sensors – which Tesla claimed would include everything needed to achieve eventually full self-driving capability – included eight cameras, a front-facing radar, and several ultrasonic sensors all around its vehicles.
The idea with Tesla Vision transition was that it would transition to only using camera-based computer vision in its Autopilot system instead of using inputs from both cameras and radars.
You’d think that more data would be better, but Tesla’s idea is that the roads are designed for humans who operate them using a vision-based system with their natural neural nets in their brains. The automaker believes it best to try to replicate that purely with cameras and artificial neural nets and not let the data from the radar pollute that.
It resulted in some Autopilot features being limited in vehicles without radar. In fact, Tesla limited the Autosteer speed of Tesla Vision vehicles to only 75 mph until May of this year.
Now Tesla is announcing that it is going a step further and removing ultrasonic sensors and replacing them by its Tesla Vision technology:
Today, we are taking the next step in Tesla Vision by removing ultrasonic sensors (USS) from Model 3 and Model Y. We will continue this rollout with Model 3 and Model Y, globally, over the next few months, followed by Model S and Model X in 2023.
The ultrasonic sensors were primarily used for short-range object detections in applications like auto-park and collision warnings.
Tesla explains how its vision neural nets are replacing the USS:
Along with the removal of USS, we have simultaneously launched our vision-based occupancy network – currently used in Full Self-Driving (FSD) Beta – to replace the inputs generated by USS. With today’s software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.
Tesla confirmed that it will again result in some feature limitations:
| Features* | Equipped with USS | Not equipped with USS |
|---|---|---|
| Forward Collision Warning | ✓ | ✓ |
| Automatic Emergency Braking | ✓ | ✓ |
| Lane Departure Warning / Avoidance | ✓ | ✓ |
| Emergency Lane Departure Avoidance | ✓ | ✓ |
| Pedal Misapplication Mitigation | ✓ | ✓ |
| Auto High Beam | ✓ | ✓ |
| Autowiper | ✓ | ✓ |
| Blind Spot Collision Warning Chime | ✓ | ✓ |
| AutoSteer† | ✓ | ✓ |
| Auto Lane Changes | ✓ | ✓ |
| Navigate on Autopilot | ✓ | ✓ |
| Traffic Light and Stop Sign Control | ✓ | ✓ |
| Park Assist | ✓ | Coming soon |
| Autopark | ✓ | Coming soon |
| Summon | ✓ | Coming soon |
| Smart Summon | ✓ | Coming soon |
Over time, Tesla will push new software updates to improve the features and release Park Assist, Autopark, Summon, and Smart Summon using its occupancy network.
Electrek’s Take
While this might be perceived as another cost-cutting effort by Tesla who will now not have to embed ultrasonic sensors into its body panels, the automaker truly believes that its vision system is a better approach.
Unfortunately, Tesla again decided to roll out the change before being ready to replace all the features.
It’s going to be interesting to track the progress of those features on Tesla vehicles without USS over the next few months.
