The invention discloses a hybrid vehicle energy distribution method and device based on predictive cruise control, electronic equipment and a vehicle. The method comprises the steps that the cruise speed and the optimal cruise requirement are preset, possible speed trajectories of the vehicle on the road section ahead are determined, and under the condition that the optimal cruise requirement is met, the speed trajectory with the minimum cost function value in all the possible speed trajectories is selected as the optimal speed trajectory, the cost function comprises at least the following cost factors: a vehicle energy consumption function and a travel time function, the optimal speed trajectory is used as a target vehicle speed trajectory for predictive cruise control of the hybrid vehicle, and the optimal speed trajectory is used as a target vehicle speed trajectory for predictive cruise control of the hybrid vehicle depending on the remaining charge of the hybrid vehicle and the optimal speed trajectory. A vehicle speed threshold for switching between battery operation and fuel operation of the hybrid vehicle is obtained. The method can find an optimal speed boundary value for a hybrid vehicle using a battery and using fuel based on predictive cruise control.
