    摘要： A vehicle steering system and a vehicle are provided. The vehicle steering system includes a steering shaft and a steering transmission shaft. The steering shaft or the steering transmission shaft includes a first shaft section and a second shaft section. A clutch mechanism is arranged between the first shaft section and the second shaft section. In an engaging state, a transmission connection is established between the first shaft section and the second shaft section and in this case, a controller determines that the vehicle enters a driving mode. In a disengaging state, the transmission connection between the first shaft section and the second shaft section is disconnected, and in this case, the control modulecontroller determines that the vehicle enters a game mode.

    摘要： A track beam includes a main component and a guide component. The main component includes a top plate, a bottom plate, and a web plate. The bottom plate is disposed below the top plate, and the web plate is connected between the top plate and the bottom plate. The guide component includes a guide plate and a connecting structure. The guide plate is disposed between the top plate and the bottom plate. The guide plate includes a planar plate structure extending in a longitudinal direction and is spaced apart from the web plate in a transverse direction. The connecting structure is connected between the main component and the guide plate such that the guide plate is connected to the main component through the connecting structure.

    摘要： The present disclosure relates to a vehicle scheduling method, apparatus, and system. The method includes: repeatedly performing following steps according to a preset scheduling period: receiving travelling information acquired by a target vehicle; searching, according to a global path of the target vehicle, a topological map for a target directional path matching the travelling information; determining a right-of-way node sequence of the target vehicle according to the target directional path and a coverage range of the target vehicle, where the right-of-way node sequence includes multiple right-of-way nodes, and the right-of-way nodes are nodes on the topological map; and determining right-of-way nodes matching the global path in the right-of-way node sequence as target right-of-way nodes in a case that each of the right-of-way nodes in the right-of-way node sequence is in a vacant state, and sending the target right-of-way nodes to the target vehicle, so that the target vehicle travels according to a path indicated by the target right-of-way nodes.
