Abstract: A reinforcement learning algorithm-based predictive control method for lateral and longitudinal coupled vehicle formation includes S1, combining a 3-DOF vehicle dynamics model that takes into account a nonlinear magic formula tire model with a lane keeping model and establishing a vehicle formation model; S2, constructing a distributed control framework and designing a local predictive controller for each following vehicle based on the vehicle formation model under the control framework; S3, using a reinforcement learning algorithm to solve the optimal control strategy of the local predictive controller, and applying the optimal control strategy to the target following vehicle. The present application completes the lateral and longitudinal coupled modeling of vehicle formation and considers the nonlinear characteristics of tires. In addition, the present application also transforms the global optimization problem of vehicle formation into a local optimization problem of each following vehicle.

Abstract: The electronic device includes a folding apparatus and a flexible display. The folding apparatus is configured to bear the flexible display. An elastic component of the folding apparatus may transfer an elastic force to the flexible display by using a housing of the folding apparatus. A force that is away from a main shaft and that is applied to the flexible display when the electronic device is in a flattened state is greater than a force that is away from the main shaft and that is applied to the flexible display when the electronic device is in a closed state.

Abstract: This application discloses a folding mechanism and an electronic device. The folding mechanism is applied to a housing apparatus of an electronic device, and is configured to connect two housings of the housing apparatus. The folding mechanism can form display accommodating space through automatic avoidance in a folding process, and a flexible display is accommodated in the display accommodating space, so that a folding action performed by the housing apparatus on the flexible display is stable, and a squeezing force is small. This helps reduce a risk that the flexible display is damaged due to excessive squeezing of the folding mechanism, and makes the flexible display more reliable.
