Driving-Performance Reduction (FLR)

The FLR function protects the brakes against overloading in the event of misuse.

If a temperature in excess of 600°C is determined, the engine power is reduced to a defined value (dependent on the type of vehicle) in order to limit the vehicle's accelerating performance. When the temperature drops below a lower limit (typically 500°C), the reduced engine torque is increased as a function of time on a ramp basis to the maximum torque again. Driving-performance reduction should only be active from a speed of 60 km/h.

This reduction of the engine torque is stored as a fault (driving performance reduction active). Should the customer find fault with the lack of engine power, this can be established by the garage/workshop and explained as brake overloading.
