2023 Volvo V90 Automatic Speed Limiter
Automatic speed limiter
The function is available in certain markets.
This function has a dynamic symbol that changes appearance when the function is active.
The colour of the symbol indicates the status of the function:
| Symbol | Meaning |
|---|---|
| Lit | The automatic speed limiter is active. |
| Grey | The automatic speed limiter is selected but in standby mode. |
Speed information from road signs
The automatic speed limiter uses speed information from the Road Sign Information function to automatically adapt the maximum speed of the car.
Road sign information bases its information on the speed limit road signs that the car passes, plus map data. Physical signs passed have top priority, which may be necessary in the case of roadworks, for example.
If road sign information cannot interpret and provide speed information to the driver support systems, the automatic speed limiter is set to standby mode and changes to the normal speed limiter. In such cases the driver must intervene and brake to a suitable speed.
The automatic speed limiter will be reactivated when road sign information can once again interpret and provide speed information.
Even if the driver clearly sees the speed-related road sign, the speed information from the Road Sign Information function to the automatic speed limiter may be incorrect – in such cases the driver must intervene him/herself and accelerate or brake to a suitable speed.
Tolerance level for automatic speed limiter
The automatic speed limiter can be set to different tolerance levels. The tolerance is adjusted in the same way as the speed setting is in the speed limiter.
If, for example, the car follows a signed speed limit of 70km/h (43 mph) the driver can instead choose to allow the car to maintain 75 km/h (47 mph).
The tolerance is followed until a road sign with a lower or higher speed is passed – then the car follows the newly signed speed limit instead and the tolerance is deleted from the memory.
The maximum selectable tolerance is +/- 10 km/h (5 mph).
