The invention relates to a deceleration method and a control device of a motor vehicle having an electric driving device. The motor vehicle comprises an operatable accelerating pedal and a brake pedal for a driver. The method comprises determining accelerating pedal operation ending, setting sliding restore torque matching with a condition that the acceleration pedal is not operated in a sliding restore range eenabling the vehicle to decelerate, during brake pedal operation, improving motor vehicle deceleration speed with maintenance of teh sliding restore,keeping maintaining the sliding restore torque matched with the condition that the accerelatinng pedal is not operated, determining operation for afterward brake pedal restore, and reducing sliding restore torque during brake pedal restore, based on the sliding resotre torque matched with the condition that the accelerating pedal is not operated.
