Abstract | This application discloses a method and an apparatus for determining a vehicle speed. During determining of a traveling speed of a vehicle, a probability distribution of intentions may be computed based on observation information of a surrounding object. Then, a probability redistribution of the different intentions is computed based on travel times required for the vehicle to travel from a current position to risk areas corresponding to the different intentions. Further, motion status variations of the surrounding object with the different intentions are predicted based on the travel times required for the vehicle to travel to the risk areas corresponding to the different intentions. Finally, the travelling speed of the vehicle is determined based on the probability redistribution of the different intentions, the motion status variations of the surrounding object with the different intentions, and motion status variations of the vehicle under different travelling speed control actions. In this way, a high risk, between the surrounding object and the vehicle, that is less likely to occur is not ignored. Therefore, a determined travelling speed is more appropriate for a current driving environment, and a potential safety risk during travelling of the vehicle is reduced. |
