Prioritized recapture of energy during deceleration of a dual-hybrid motor vehicle

摘要

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.
