REDUCE speed
The vehicle speed is reduced by reducing the drive torque. The following activities are started in this case:
- Engine torque reduction
The engine management system implements the "Reduce engine torque" request.
- Gear downshift (vehicles with automatic transmission)
The transmission management system implements the "Shift down gear" request.
- Service brake actuation
If the drive torque reduction is not sufficient to decelerate the vehicle, the brake system actuates the service brake.
