A Method for Predicting Performance Degradation and Decision-Making of Asphalt Pavement on Highways

This invention relates to the field of intelligent highway maintenance technology, specifically to a method for predicting performance degradation and making maintenance decisions for asphalt pavement on highways. The method includes the following steps: S1, collecting multi-source data from highway sections, including static structure, dynamic traffic, environmental monitoring, and historical data; S2, using an LSTM model to predict pavement performance indicators for future periods based on the multi-source data, including the Pavement Damage Index (PCI), Ride Quality Index (RQI), Rutting Depth (RD), and Skid Resistance Index (SRI); S3, detrending the performance indicators to obtain a stationary residual sequence, and calculating the critical degradation index; S4, comparing the critical degradation index with a preset warning threshold and safety threshold, and adaptively adjusting the maintenance trigger threshold based on the comparison result; S5, using the adjusted maintenance trigger threshold as a constraint condition, inputting it into a multi-objective genetic algorithm to generate the optimal maintenance plan.

A human-machine double preview coupling stable front-axle active suspension control method and system

PendingCN122501098ADynamic modelsIn vehicle
This invention discloses a human-machine dual-pre-aiming coupled and stable front axle active suspension control method and system, belonging to the field of vehicle active suspension control technology. This invention integrates driver control pre-aiming and machine road surface pre-aiming to construct a human-machine dual-pre-aiming coupled dynamic model, accurately characterizing the impact of coupled disturbances on the suspension, achieving quantitative determination of stability and hierarchical collaborative control. The system dynamically optimizes multi-objective control weights based on real-time operating conditions, prioritizing ride comfort in stable operating conditions and safety in emergency and dynamic operating conditions, achieving a synergistic improvement in comfort and stability. With zero hardware increments and lightweight algorithms, it can be directly integrated into the vehicle ECU, reusing onboard sensing and execution components, adapting to mass-produced solutions such as CDC and air suspension, and can be coordinated with ESP and ABS for overall vehicle ride quality, handling safety, and system robustness, possessing excellent engineering practicality and promotional value.

Electric vehicle load leveling systems and methods

An electric vehicle may be equipped with an adaptive suspension system that includes a chassis, a suspension system coupled to the chassis, and at least one helper spring configured to assist the suspension system. The vehicle may include at least one sensor configured to measure suspension travel, including vertical displacement between the vehicle's wheels and body. A controller, coupled to the helper spring and the sensor, may adjust the stiffness of the helper spring based on the measured travel. The stiffness of the helper spring may be varied in response to changes in load, such as added or removed weight, to improve ride quality, stability, and handling. The system may further include multiple helper springs, a user interface for manual adjustment, and an automatic adjustment feature based on the suspension's measured travel.

A control method, device and system for improving lateral ride comfort of an aircraft

The application provides a control method, device and system for improving cross-direction ride comfort of an airplane, and belongs to the technical field of flight control. Three sets of lateral acceleration sensors are arranged on the longitudinal axis of the airplane, and are respectively located at the front cabin nose, the airplane body centroid and the rear cabin tail, so as to obtain lateral overload signals of different positions of the airplane when the airplane is disturbed by crosswind. In combination with three-axis angular velocity signals of the airplane, the front cabin additional lateral overload and the rear cabin additional lateral overload are obtained after filtering processing. Through gain adjustment and amplitude limiting superposition, target aileron differential instructions and target rudder instructions are formed, the aileron and the rudder are deflected to generate lateral force and moment, the lateral force influence brought by the gust disturbance is offset, and the purpose of improving the passenger ride comfort is achieved. The application has simple hardware structure, high signal reliability and easy engineering implementation, and can be used for improving the long-time cross-direction ride quality of a large passenger airplane.
