The embodiment of the invention provides a braking energy recovery method, a controller and a computer readable storage medium, and belongs to the technical field of automobile control. The method comprises the steps that the current brake pedal opening degree and the preset brake pedal opening degree are obtained; a target electric braking torque is obtained according to the current brake pedal opening degree and the preset brake pedal opening degree; the actual electric braking torque is obtained, and the final recovery torque is determined according to the actual electric braking torque and the target electric braking torque; and adjusting the driving motor to recover the braking energy according to the final recovery torque. According to the embodiment of the invention, the target electric braking torque with relatively high braking energy recovery efficiency can be determined by utilizing the current brake pedal opening degree and the preset brake pedal opening degree, then the final recovery torque is determined by utilizing the target electric braking torque and the actual electric braking torque, and the driving motor is adjusted according to the final recovery torque; therefore, the braking energy recovery efficiency can be improved, and the endurance mileage of the electric automobile is increased.
