The invention relates to the technical field of new energy automobiles, and provides a hybrid electric vehicle brake control method and device and an automobile. The method comprises the steps that under the condition that the automobile travels downhill, the predicted automobile speed and the safe automobile speed of the automobile within the future preset duration are calculated; according to the road surface condition and weather in front of the automobile, a target braking mode in the future preset duration is determined; and the braking force of the target braking mode is determined according to the difference between the predicted vehicle speed and the safe vehicle speed. According to the method, the braking force of the corresponding target braking mode is adjusted by estimating the safe speed of the automobile in the future duration and combining the road condition and the weather, so that the speed of the automobile is close to the safe speed, and the safety of the automobile during downhill driving is improved.
