The invention provides a method and device for controlling the speed of a vehicle, a control system and a storage medium. The method comprises the following steps: acquiring a motion trend of at least one target object in a preset range in front of a vehicle; according to the motion trend of each target object, determining a first class of objects and a second class of objects in the at least one target object, the first class of objects being target objects whose longitudinal distances from the vehicle within unit time are reduced, and the second class of objects being target objects whose longitudinal distances from the vehicle within unit time are reduced; the second class of objects are target objects of which the transverse distances with the vehicle in unit time are reduced; determining the minimum vehicle speed at which the vehicle does not collide with each first-class object and each second-class object respectively; according to each minimum vehicle speed, determining a target vehicle speed of the vehicle; and controlling the running speed of the vehicle according to the target vehicle speed. According to the method, the danger degree of the current environment of the vehicle can be comprehensively evaluated, the possible safety driving risk problem is avoided, and the safety driving performance of the vehicle is remarkably improved.
