Patent ID: 7597408

Claim:
A method for compensating a regenerative braking amount when regenerative braking of a vehicle fails, comprising: determining whether or not the regenerative braking is activated; remembering a regenerative braking control amount in a hybrid control unit and an electronic brake system, if determined that the regenerative braking is activated in the previous step; calculating a braking amount for failure check in the hybrid control unit and the electronic brake system when there occurs a failure related to the regenerative braking; learning and remembering a difference between the regenerative braking control amount in a normal state calculated just before the failure and the braking amount for the failure check in the hybrid control unit and the electronic brake system; compensating the braking amount for the failure check with the difference value between the normal regenerative braking control amount and the braking amount for the failure check; and performing a regenerative braking control in the hybrid control unit and the electronic brake system respectively.
