The invention relates to the technical field of unmanned driving, automatic driving and unmanned vehicles, and discloses an unmanned vehicle control method and device on a bumpy road surface, an unmanned vehicle and a storage medium. The method comprises the following steps: determining a driving control strategy of the unmanned vehicle according to the bumping degree of a current road surface; under the condition that the driving control strategy represents that the unmanned vehicle needs to be controlled to decelerate, a vertical bumping characteristic signal set representing the bumping degree within a preset distance range is obtained; calculating a longitudinal acceleration constraint corresponding to each vertical bumping characteristic signal in the vertical bumping characteristic signal set based on a linear mapping relationship between the longitudinal acceleration and the vertical bumping characteristic signal, and screening a maximum longitudinal acceleration constraint; and based on the maximum longitudinal acceleration constraint, determining a target vehicle speed after the unmanned vehicle is decelerated, and controlling the unmanned vehicle. According to the invention, intelligent recognition and self-adaptive speed control of the unmanned vehicle on the bumpy road surface are realized, so that the vehicle can automatically adjust the driving speed according to the road surface bumpy degree detected in real time.
