The subject of this article is on-board information control systems that ensure the movement of heavy vehicles in a convoy with the driver only in the first car, as well as cruise control systems, including adaptive and intelligent ones. The purpose of the article is the formation of the specified on-board system of a heavy truck, which includes both a set of algorithms and key functions that implement movement in a column, and a list of used categories of sensors. All considered functions are arranged hierarchically at three levels: strategic, tactical and operational. The study collected both theoretical and practical information provided by automakers, revealing the essential content of onboard information systems and cruise control. The novelty of the study lies in the fact that the model of intellectual cruise control has been improved, providing movement of heavy vehicles in a convoy, if there is a driver only in the first car. The proposed model includes the hierarchical architecture of the on-board information management system, key algorithms and sensors for its implementation.

A wide variety of ways to analyze the end-to-end latency emerges due to the feature of component-based software. The researchers began to see that the latency is more sensitive to the data and control flows than the software architecture. However, for an embedded software, the latency depends upon the hardware heavily. To illuminate the feature clearly, we extend the atomic model of component-based software first. A way to specify the flows involved is further developed to identify the end-to-end latency. What is more, a novel methodology that bridges the gap between a constraint on latency and an execution platform is proposed for the embedded software. By constructing a hierarchical architecture, it is available to consider the methodology as a decision problem where the satisfiability module theory (SMT) can be applied. Experimental results demonstrate how the latency analysis conducts with the proposed model and methodology for the complex software architecture.

Abstract The approach to formalization of complex organizational and technical systems based on the toposes theory is substantiated. The article presents a review of the literature on the formalization of knowledge. An integrated control system for technical complexes is considered. The description of blocks of intelligent information and control systems based on the toposes theory is developed. An algorithm for formalizing intelligent information and control systems and an example of constructing toposes and functors for the general case are presented. The conclusion is made about the possibility of applying the proposed approach to the formalization of the intelligent information and control systems in the process of formation of their appearance.

Commercial vehicles display a large variation in their parameters, and due to many current trends in vehicle control systems, identifying these parameters has been the subject of much research. Using the National Center for Asphalt Technology’s test track and instrumented Freightliner vehicles as a test bed, this paper sets out to provide analysis of real world and simulated estimation results and explore how sensor accuracies can degrade these results. Various vehicle parameters are identified using both the existing test conditions of the facility and simulated data. The estimation accuracy and performance are then analyzed for validation and use in other vehicle design arenas.

The undertaking was finished so one can pick out the effectiveness of the worker pride level closer to the recruitment and schooling manner going on inside the corporation. The powerful become measured utterly based totally at the opinion of the employees and workers in all level, it's also analyzed with various statistically announcement and studied approximately the sources. The examine turned into finished because the management wanted to find out the various factors that affected the advantages of the schooling for the personnel. corporation is imparting education programs and seminars, and numerous different improvement applications also. on the subject of those info a established questionnaire changed into prepared. Which became used to get response from a pattern of 250 personnel? on this have a look at Descriptive research design turned into used and comfort Sampling approach was used as the sampling process, and records obtained were statistically analyzed the usage of Chi-rectangular test and Kolmogrov Smirnov D take a look at and Kendall's Concordance check. The evaluation and interpretations enables to identification the findings and suggestion of the workers. Recruitment bureaucracy the primary level within the process which keeps with choice and ceases with the location of the candidate. it is the next step within the procurement feature the primary being the manpower planning. Recruiting makes it viable to gather the range and kinds of humans essential to make certain the ongoing operation of the corporation. Recruiting is the discovering of potential applicants for actual or expected organizational vacancies. In other words, it's far a linking interest bringing together these with jobs and people seeking jobs. Recruitment has been seemed because the maximum vital characteristic of personnel administration, because unless the proper type of humans are hired, even the exceptional plans, agency charts and control systems might not do much correct. Recruitment both as high-quality? and terrible? hobby. it's far a procedure of trying to find potential personnel and stimulating and inspiring them to apply for jobs to boom the hiring ratio?, i.e., the range of applicants for a task. selection, on the other hand has a tendency to be poor as it rejects a great member of who follow, leaving most effective the pleasant to be employed .

The article discusses the heat and mass transfer dynamic model for an electric heater with lumped parameters, which allows transient processes simulation for the main influences. The proposed model is recommended to be used in cyber-physical systems for forecasting and evaluating the effectiveness of control systems integrated into a single information management system. The developed model can be used by specialists for the analysis and synthesis of control systems for balanced ventilation systems or industrial air conditioners. As an example, a numerical simulation of transient processes along the action main channels for an electric heater HE 36/2 manufactured by VTS CLIMA was carried out. The significant advantage of the proposed model is the possibility for using it for the synthesis and analysis of multidimensional control systems.

State And Control Constraints

A new decision algorithm for ACC systems is proposed. Feasible driving set is defined based on state and control constraints, which represent driver behavior features. And based on the analysis of collected driving data, a second-order range policy is selected to approach real driver behavior. Under dynamic output feedback control framework, the decision algorithm has been developed based on quadratic boundedness theory and given in terms of linear matrix inequalities. Performance of the proposed algorithm is verified by Simulink and Carsim co-simulation.
