The invention relates to automobile energy recovery and aims at providing an automobile brake energy recovery device and a segmented control method thereof. The device comprises a super-capacitor and a motor, a low-voltage-end ampere meter, a bidirectional Buck-Boost converter, a high-voltage-end ampere meter, a PWM controller, a low-voltage-end relay and a high-voltage-end relay, wherein the low-voltage-end relay and the high-voltage-end relay refer to single-pole double-throw switches and comprise movable contacts, first stationary contacts and second stationary contacts; the low-voltage-end ampere meter is arranged between the super-capacitor and the movable contact of the low-voltage-end relay; the high-voltage-end ampere meter is arranged between the motor and the movable contact of the high-voltage-end relay; and each piece of equipment is connected to the PWM controller by virtue of a signal line. The automobile brake energy recovery device can be directly applied to the conventional electric automobiles and hybrid electrical vehicles, the brake energy recovery efficiency is improved, the energy-saving effect is improved, and the driving range is prolonged.
