The invention provides a regenerative braking control method and device. When a vehicle starts to be braked, braking force of regenerative braking is increased step by step at the set slope, the danger of vehicle impact caused by excessive braking at the beginning of regenerative braking is avoided, and because of stable braking, the riding comfort of passengers or a driver is improved; when the vehicle is not braked, regenerative braking is decreased step by step at the set slope, the vehicle speed is lowered step by step till the braking force exits and the vehicle stops operating, the situations that regenerative braking is instantly retracted, consequently the vehicle speed is prone to forming excessive impact, and the danger of rear-ending of the vehicle is caused are avoided, and thetraveling safety of the vehicle is improved; and in the process of the regenerative braking, if an ABS participates in work, regenerative braking exits in a slope mode, in the braking process, even if the ABS no longer works, regenerative braking does not act any more, and the risks that during working of the ABS, regenerative braking works frequently and does not work, consequently vehicle impact is serious, and rear-ending of the vehicle is caused are avoided.
