PPC (Predictive Powertrain Control)
Example: speed tolerances display
PPC uses topographic map data to optimise fuel
consumption and to adjust output according to
operating conditions. PPC influences gear
selection and adjusts the speed of cruise control
or distance control assistant. The speed adjust-
ment facilitates better utilisation of momentum
accumulated on downhill gradients. On uphill
gradients, the power output is optimised and
may be reduced before the top of the hill is
reached. You can adjust the speed tolerances in
the Eco-Drive menu window (
Y
page 283).
