The invention discloses a planetary gear type transmission, an automobile power system and an automobile, the planetary gear type transmission comprises a transmission shell, an input main shaft, an output main shaft, a two-gear shifting brake assembly and a double-planet-row assembly, and the input main shaft and the output main shaft are arranged on the transmission shell; the double-planet-row assembly comprises a sun gear, a double-planet-gear assembly and a transmission inner gear ring. The two-gear shifting brake assembly comprises an inner side brake assembly and an outer side brake assembly which are arranged in an installation cavity of the transmission shell and arranged inside and outside, and the outer side of the outer side brake assembly is fixedly connected to the transmission shell in combination with a brake part. The two adjacent combined braking parts of the two braking assemblies are connected with one of the double-planet-wheel assembly and the transmission inner gear ring, the output main shaft is connected with the other one of the double-planet-wheel assembly and the transmission inner gear ring, the inner side combined braking part of the inner side combined braking assembly is connected with the sun wheel and the input main shaft, and braking is achieved through alternate combined braking of the inner side braking assembly and the outer side braking assembly. Two-gear speed change of the transmission is achieved, and the dynamic property is improved.
