One energy recovery system (30) that can decelerate the vehicle in
response to a brake request stores recovered energy electrically in a
battery bank (32). Another energy recovery system (36) stores recovered
energy hydraulically in a high pressure accumulator (40). One system is
given priority over the other when a brake request is issued. When the
stored energies are reused to accelerate the vehicle, one form of stored
energy is used before the other.
