Patent ID: 7472766

Claim:
A regeneration control system of a vehicle, comprising: a first electric motor connected to front wheels and a second electric motor connected to rear wheels so as to carry out regeneration by the first and the second electric motors in a deceleration mode; total regeneration amount determining means for determining a total regeneration amount of the vehicle on the basis of a running condition of the vehicle for a predetermined time interval; regeneration amount allocation determining means for determining the allocation of a regeneration amount to each of the first and the second electric motors relative to a total regeneration amount on the basis of a vehicle speed and the steering angle of a steering wheel when the total regeneration amount has been determined by the total regeneration amount determining means; determination value calculating means for calculating a determination value for determining a behavior of the vehicle on the basis of the steering angle of the steering wheel and a yaw rate when the allocation of the regeneration amount has been determined by the regeneration amount allocation determining means; determining means for determining whether the determination value calculated by the determination value calculating means lies in a predetermined range defined beforehand; selecting means for selecting, if the determining means determines that the determination value lies in the predetermined range, the allocation of a regeneration amount determined by the regeneration amount allocation determining means at that point, or for selecting, if it is determined that the determination value lies out of the predetermined range, the allocation of a regeneration amount determined by the regeneration amount allocation determining means at the point when the determination value lied in the predetermined range immediately before it deviated from the predetermined range; and regeneration command issuing means for issuing a command of a regeneration amount to each of the first and the second electric motors on the basis of the regeneration amount allocation selected by the selecting means.
