The invention discloses an automobile braking energy recovery method and device, and relates to the technical field of automobiles. In the vehicle braking process, the whole vehicle braking force requirement is determined according to the brake pedal stroke of the vehicle, and the first maximum recycling torque corresponding to the rotating speed of a first hub motor, the second maximum recycling torque corresponding to the rotating speed of a second hub motor and the third maximum recycling torque corresponding to the rotating speed of a concentrated motor are obtained; in this way, the vehicle can be controlled to achieve braking energy recovery based on the magnitude relation between the sum of the first maximum recovery torque, the second maximum recovery torque and the third maximum recovery torque and the braking force requirement of the whole vehicle, and braking energy recovery of the distributed three motors is achieved.
