Speed Assist with Autopilot Tesla Model Y

Other electrical equipment or gadgets that create ultrasonic waves have an impact on the sensors.

Warning: Autopark's ability to park Model Y may be hampered by a variety of unforeseen conditions. Keep this in mind, and keep in mind that Autopark may not be able to steer Model Y properly as a result. When parking the Model Y, pay attention and be ready to take control right away.

See Autopilot Overview and Features.

When Model Y is unable to determine a speed limit, or when Speed Assist is unsure whether an obtained speed limit is accurate, the touchscreen may not display a speed limit sign, and warnings will not be displayed.

When the speed limit warning is set to Display and you go over the set speed limit, the speed limit sign on the touchscreen grows in size.

When the speed limit warning is set to Chime and the vehicle exceeds the set speed limit, the speed limit sign on the touchscreen grows larger and the Model Y emits a warning chime.

When the Model Y slows down below the specified limit, the speed limit alerts disappear after ten seconds.

Warning: Speed Assist should not be used to establish the proper speed limit or driving speed. Drive at a safe speed based on traffic and road conditions at all times.


To Control Speed Assist

Touch Controls > Autopilot > Speed Limit Warning, then select one of the following options to alter the Speed Limit Warning setting:

  • Off - There are no speed limit warnings displayed or chimes sounded.
  • Display - When you exceed the set speed limit, the speed restriction sign appears on the touchscreen and grows in size.
  • Chime - When you exceed the determined speed restriction, a chime is emitted in addition to the visible display.

You can also define the method for determining the speed limit:

  • Relative - If you wish to be warned only when you exceed the offset speed limit by a certain amount, you can define a speed limit offset (+ or -). If you only want to be notified when you exceed the speed limit by 10 mph (10 km/h), for example, you can adjust the offset to +10 mph (10 km/h).
  • Absolute - Set any speed limit between 20 and 140 mph (30 and 240 km/h) on the fly.

Please keep in mind that Speed Assist is not always correct. When the position of a road is miscalculated, Speed Assist may display a speed for a road right adjacent to it, which may have a different speed restriction. Speed Assist, for example, may believe the Model Y is on a freeway or highway while it is actually on a neighbouring surface street, and vice versa.

Note: Unless you alter it manually, your chosen configuration remains in effect.


Limitations and Inaccuracies

In the following conditions, Speed Assist may not be fully functioning or may provide erroneous information:

  • Visibility is poor, and speed limit signs are obscured (due to heavy rain, snow, fog, and other factors).
  • The camera's view is obstructed by bright light (such as from incoming headlights or direct sunshine) (s).
  • The Model Y is being driven dangerously close to a vehicle in front of it, obstructing the camera's vision (s).
  • The camera(s) can't see through the windshield because it's fogged up, dusty, or covered by a sticker, for example.
  • Objects obscure the speed limit signs.
  • The map database's speed limits are erroneous or out of current.
  • The Model Y is being driven in a region without GPS or map data.
  • There are no standard identifiable formats for traffic signs.
  • There has been a recent adjustment to a road or a speed limit.

Warning: The preceding list does not represent a complete list of scenarios that could cause Speed Assist to malfunction. For a variety of reasons, Speed Assist may fail to offer warnings.
