Vehicle cruise control method and device, vehicle and storage medium

The invention relates to the technical field of vehicles, in particular to a cruise control method and device of a vehicle, the vehicle and a storage medium. If the current working condition is the cruise working condition, obtaining a target cruise speed according to the actual speed of the current vehicle, and obtaining a first target acceleration based on the difference between the actual speed and the target cruise speed; and calculating a first driving torque or a first braking torque of the current vehicle according to the first target acceleration, and controlling a braking system to perform energy recovery electric braking and hydraulic braking based on the first braking torque, or controlling a driving motor to execute the first driving torque. Therefore, the efficiency loss of the vehicle during switching of driving and energy recovery and mutual conversion of electric energy and mechanical energy can be effectively avoided, the vehicle running smoothness is improved, the energy consumption rate of
