Abstract
A method of increasing engine braking of an engine for a vehicle, the method including: determining the change in kinetic energy of the vehicle over a period; determining the energy output from a drivetrain of the vehicle over the period; comparing the change in kinetic energy to the energy output; and increasing the engine braking of the vehicle when the change in kinetic energy is greater than the energy output over the period.
