ADAS improvements
Pilot Assist gains AI-based lateral control that follows lane edges for natural steering, with Lane Keeping Aid adding a vibrations-only option. ACC and Pilot Assist now work up to 180 km/h and 150 km/h respectively, with smoother acceleration, fewer unnecessary brake interventions, and improved driver-not-detected alerts.
Pilot Assist now uses a new AI-based method for lateral control, following the drive path within the lane instead of just the center. The steering control will now handle road curves in a more natural manner.
- This does not reduce the driver's responsibility to operate the vehicle as safely as possible.
Lane Keeping Aid now improved to include a setting for steering wheel vibrations only
- Previously the Lane Keeping Aid system only offer ON and OFF settings, with the ON setting using both steering interventions and vibrations. You can now select "vibrations only" or "vibrations and steering interventions" when selecting ON. Please note that steering interventions will still be active for solid road lines and edges.
Pilot Assist now works at speeds up to 150 km/h. If your speed exceeds 150 km/h while using Pilot Assist, lateral control will automatically resume when the speed drops below 150 km/h
Adaptive Cruise Control (ACC) now works at speeds up to 180 km/h
Tuning improvements to ACC and Pilot Assist to provide a smoother acceleration and braking experience
Pilot Assist improved to avoid unnecessary brake interventions while driving.
“Driver Not Detected” warning system improved to reduce the number of false alerts
