ABSTRACT:
A method for compensating a regenerative braking amount when regenerative braking of a vehicle fails due to an error in controller area network (CAN) communications between an electronic brake system (EBS) and a hybrid control unit (HCU). The method includes steps of determining whether or not the regenerative braking is activated, remembering a regenerative braking control amount in the HCU and the EBS, 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 HCU and the EBS, 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 HCU and the EBS respectively.
