1. A computer-implemented method of open loop control of a retardation torque of a vehicle, the method comprising:
obtaining, by a processor device of a computer system, a current vehicle acceleration indicator,
obtaining, by a processor device of a computer system, one or more current vehicle state indicators,
determining, by a processor device of a computer system, an open loop retardation torque based on the vehicle acceleration indicator and the one or more vehicle state indicators, and
controlling, by a processor device of a computer system, a resulting retardation torque applied by one or more propulsion sources of the vehicle based on the open loop retardation torque.
