The invention discloses an unmanned vehicle formation dynamic control method and system. The method comprises the following steps: collecting perception information of a current environment through a sensor and communication equipment; analyzing and determining the formation with the highest efficiency under the current condition according to the collected sensing information; establishing a master-vehicle and slave-vehicle formation model, and enabling each unmanned vehicle to move according to a kinematical equation of the master-vehicle and slave-vehicle formation model; an error dynamic model is established, and an error control method is designed, so that the tracking error between the slave vehicle and the master vehicle is converged to a minimum neighborhood; when a task vehicle needs to drive away from the formation, the task vehicle predicts the tracks of other vehicles and performs obstacle avoidance driving based on a dynamic prediction obstacle avoidance control method; and performing formation switching according to the current environment conditions and task requirements. According to the invention, the formation generation and maintenance capability of the unmanned vehicle formation can be improved in a complex environment, the formation obstacle avoidance strategy is optimized, and the balance between the formation and an independent task is realized.

This disclosure relates to a control method, device, vehicle, and storage medium for an active suspension system. The method includes: acquiring a first distance between the vehicle and an obstacle before the vehicle's camera enters a blind spot, and the total number of pulses generated by the vehicle after the camera enters the blind spot, the pulse count increment per tire revolution, and the tire circumference; determining the distance traveled by the vehicle after entering the blind spot based on the total number of pulses, the pulse count increment, and the tire circumference; and determining the active force applied to the active suspension based on the first distance and the travel distance, so that the vehicle triggers control of the active suspension based on the active force. This disclosure compensates for distance signals that the camera cannot recognize within the blind spot area by calculating the travel distance in real time, and provides independent control logic for the active suspension, thereby improving the vehicle's stability when encountering road obstacles.

An apparatus (200) according to an aspect of the present disclosure includes: an information obtaining unit (231) configured to obtain path related information associated with a moving path of the apparatus; and a communication processing unit (235) configured to transmit a radio resource control, RRC, message including the path related information to a base station (100). The RRC message including the path related information is an RRC message initiated by the apparatus.
