1. A method of operating a vehicle, comprising:
acquiring, by processing circuitry from a first vehicle retarding subsystem, at least one value indicative of current energy accumulation by the first vehicle retarding subsystem;
determining, by the processing circuitry, a measure indicative of a retardation energy capacity currently available for retardation of the vehicle, based on:
the acquired at least one value indicative of current energy accumulation by the first vehicle retarding subsystem;
a predefined model of retardation energy accumulation by the first vehicle retarding subsystem; and
a predefined limit indicative of a maximum allowed energy accumulation by the first vehicle retarding subsystem; and
determining a measure indicative of a sustainable retardation power provided by the vehicle without accumulation of retardation energy by the at least first vehicle retarding subsystem.
