Abstract

A method of open loop control of a retardation torque of a vehicle is presented. The method comprises obtaining of a current vehicle acceleration indicator, obtaining of one or more current vehicle state indicators, and determining of an open loop retardation torque based on the vehicle acceleration indicator and the one or more vehicle state indicators. The method further comprises controlling of a resulting retardation torque based on the open loop retardation torque. The resulting retardation torque is applied by one or more propulsion sources of the vehicle.
