Classification: CPC B  F  Y | IPC B

Claim 9:
10. A vehicle control unit, for controlling operation of a vehicle comprising at least a first vehicle retarding subsystem controllable to retard the vehicle, the vehicle control unit being configured to:
acquire, from the first vehicle retarding subsystem, at least one value indicative of current energy accumulation by the first vehicle retarding subsystem;
determine 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

determine 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.
