Tesla’s Hardware 2 Sensor Suite

Tesla revealed their current production vehicles are equipped with the necessary hardware for autonomous driving capabilities.

They mention:

  • 8 surround cameras providing 360 degree visibility around the car
  • 12 ultrasonic sensors
  • 1 forward-facing radar unit
  • 1 on-board computer

Cameras

  1. Wide forward camera
  2. Main forward camera
  3. Narrow forward camera
  4. Driver’s side rearward looking side camera
  5. Passenger’s side rearward looking side camera
  6. Driver’s side forward looking side camera
  7. Passenger’s side forward looking side camera
  8. Rear View camera

Camera type, location, FOV, distance and use:

Type Mounting Location Field of View Max Distance Function
1 Wide forward camera Interior: Triple camera, above rear-view mirror 120 degree fish-eye 60m (~197 ft.) Captures traffic lights, obstacles cutting into the path of travel and objects at close range. Particularly useful in urban, low speed maneuvering
2 Main forward camera Interior: Triple camera, above rear-view mirror Unknown, assumed ~50 degree 150m (~492 ft.) Covers a broad spectrum of use cases
3 Narrow forward camera Interior: Triple camera, above rear-view mirror Unknown, assumed ~25 degree 250m (~820 ft.) Provides a focused, long-range view of distant features. Useful in high-speed operation
4 Driver’s side rearward looking side camera Exterior: fender badge mounted Unknown 100m (~328 ft.) Monitor rear blind spots important for safely changing lanes and merging into traffic
5 Passenger’s side rearward looking side camera Exterior: fender badge mounted Unknown 100m (~328 ft.) Monitor rear blind spots important for safely changing lanes and merging into traffic
6 Driver’s side forward looking side camera Exterior: B pillar mounted 90 degree 80m (~262 ft.) Detect cars unexpectedly entering your lane and additional safety when entering intersections with limited visibility
7 Passenger’s side forward looking side camera Exterior: B pillar mounted 90 degree 80m (~262 ft.) Detect cars unexpectedly entering your lane and additional safety when entering intersections with limited visibility
8 Rear View camera Exterior: Hatch latch area mounted Unknown 50m (~164 ft.) Backing up safely, contributing member of the Autopilot hardware suite, useful when performing complex parking maneuvers

Note: locations correspond to Model X locations

Radar

The forward looking radar’s range falls between the Narrow and Main camera’s distance with a max range of 160m (~525ft).

Ultrasound

These are the shortest range sensors, with a max distance of 8m (~26ft)

Computer

NVIDIA Drive PX 2  with more than 40 times the computing power of the previous generation unit in Tesla vehicles
