Abstract The article offers an algorithm for the operation of the steering and active drive control system of a saddle-type tractor – trailer combination. The algorithm allows reducing the width of the cornering corridor when maneuvering at low speeds. In the combination vehicle under study, all the wheels of the tractor and semi-trailer are driving and steered. The algorithm of the steering control system takes into account the current values of the folding angle and speed of the combination vehicle. The active drive control is based on the analysis of the forces in the coupling device. The efficiency and effectiveness of the proposed algorithm has been proved using computational experiments.

Objective: The cotton textile industry, as a competitive industry in China's international competition, is confronting new opportunities and challenges brought by the growing process of mechatronics. To further improve the traditional drive control of combing machines made in China and the automatic level of machines as a whole, some of our cotton textile enterprises have undertaken necessary technical transformations on the combing machines so as to raise the operational efficiency and production technology of domestic textile equipments. Methods: This paper focuses on the basic status and dynamic characteristics of the drive part of the domestic new comber, and analyzes the operation process of the comber and the prominent problems from the production practice. Results: The technically improved drive control system uses an industrial control computer (IPC) as the core of the system, which effectively improves the overall working efficiency of the comber, and improves the production accuracy and production efficiency. Conclusion: The combers that are textile machinery equipments with comprehensive application of machines, electricity, gases and instruments, play a vital role in enhancing product quality and production efficiency. Highly intelligent and integrated process control, real-time monitoring and accurate data acquisition and data analysis have become the mainstreams in the development of auto-control. Therefore, the commitment of high technology to transform the traditional production mode has also been an important research.

For L4 and above autonomous driving levels, the automatic control system has been redundantly designed, and a new steering control method based on brake has been proposed; a new dual-track model has been established through multiple driving tests. The axle part of the model was improved, the accuracy of the transfer function of the model was verified again through acceleration-slide tests; a controller based on interference measurement was designed on the basis of the model, and the relationships between the controller parameters was discussed. Through the linearization of the controller, the robustness of uncertain automobile parameters is discussed; the control scheme is tested and verified through group driving test, and the results prove that the accuracy and precision of the controller meet the requirements, the robustness stability is good. Moreover, the predicted value of the model fits well with the actual observation value, the proposal of this method provides a new idea for avoiding car out of control.

Yaw Moment

Basically, there are two main techniques to control the vehicle yaw moment. First method is the indirect yaw moment control, which works on the basis of active steering control (ASC). The second one being the direct yaw moment control (DYC), which is based on either the differential braking or the torque vectoring. An innovative idea for the direct yaw moment control is introduced by using an active controller system to supervise the lateral dynamics of vehicle and perform as an active yaw moment control system, denoted as the stabilizer pendulum system (SPS). This idea has further been developed, analyzed, and implemented in a standalone direct yaw moment control system, as well as, in an integrated vehicle dynamic control system with a differential braking yaw moment controller. The effectiveness of SPS has been evaluated by model simulation, which illustrates its superior performance especially on low friction roads.
