NOVELTY - The braking method involves determining the braking torque overall value using the first, second and third braking torques to give priority to the contribution of the third braking torque for the highest energy recovery. The first braking torque and second braking torque are provided by the thermal engine (MT) of the hybrid traction system. The first braking torque is derived from engine friction. The second braking torque is derived from one or more additional braking systems operating on the thermal engine or on a transmission of a vehicle.    USE - Braking method with energy recovery for vehicle (claimed) with hybrid traction system and service brakes.    ADVANTAGE - Ensures that the overall braking action is performed by various contributions that may be added up and that may vary in time according to the different situations. Resolves the problem that when the battery is charged, the electric brake is no longer able to contribute to the braking because the engine-generator does not deliver electric current and cannot convert the kinetic energy into electric energy as a generator. Ensures that the service brake will be always available, even though it will be used as less as possible. Ensures that the service brake is not subject to the direct control of electronic control unit (ECU), but is positively influenced by it, in the sense that the whole braking contribution deriving from the additional braking system serves to reduce the request to the service brake.    DETAILED DESCRIPTION - An electric engine-generator (ME) is connected to one or more battery systems (BAT). The battery systems provide the third battery torque if the electric engine-generator functions as a generator. INDEPENDENT CLAIMS are also included for the following:    (1) Braking device with energy recovery;    (2) Computer program comprising of program codes for performing braking method with energy recovery; and    (3) Computer-readable medium for storing the computer program for performing the braking method with energy recovery.
