🚦 Speed Limit Control (SLC)
Speed Limit Control (SLC) automatically adapts the cruise speed to road limits by using speed limit signs information from map data and the car interface.
HKG only: Highway Driving Assist (HDA) status integration is available on applicable HKG cars.
SLC Supports Selecting Different Policies:
SLC allows users to choose the source of speed limit data that will be used to adjust the cruise speed. The options are:
- Nav Only: Uses navigation data from a loaded Mapbox route to determine speed limits.
- Map Only: Relies solely on OpenStreetMap (OSM) data for speed limit information.
- Car Only: Utilizes the car's built-in data, such as camera or navigation system, to determine speed limits.
- Nav First: Gives priority to navigation data, followed by map data, and finally car data.
- Map First: Prioritizes map data, followed by navigation data, and then car data.
- Car First: Prioritizes car data, followed by navigation data, and then map data.
OpenStreetMap (OSM) Speed Limit Prediction
Any option that uses OSM data is capable of predicting the next speed limit for a more natural drive, dependent on having offline data or onboard connectivity via SIM or hotspot. However, when OSM is not the priority source, the prediction will only kick in if the priority source returns no information regarding the speed limit.
When Speed Limit Control is enabled, you can set the speed limit offset to be either a percentage (%) or a static value:
- Percentage Offset: Adjusts the speed limit by a certain percentage above the actual speed limit.
- Static Offset: Adds a fixed value to the actual speed limit.
This allows for a more natural drive while still adhering closely to road regulations.
