The invention discloses a brake control method of a hybrid electric vehicle. The method comprises the following steps of obtaining the total demand braking force T, the largest brake braking force T1max and the largest energy recovery braking force T2max of the current vehicle; selecting the brake braking force T1 within 0-T1max, selecting the energy recovery braking force T2 within 0-T2max, meeting the conditions that the sum of the T1 and the T2 is equal to the T, obtaining a plurality of sets of T1 and T2, calculating the brake cost F corresponding to each set, and finding out a set of T1 and T2 with the smallest F; and controlling a brake braking output value and an energy recovery braking output value to be the set of T1 and T2 with the smallest F. According to the brake control method, brake braking and energy recovery braking can be mutually related and matched for use, so that economy and safety are high.
