TR TR TR DESCRIPTION Automatic power and torque control system in work machines TECHNICAL FIELD The invention is generally related to the automatic power and torque control system used in work machines. The invention is especially aimed at automatic power and torque control with high sensitivity and accuracy, which provides hydraulic system power control by gradually controlling the data transmitted from the engine in work and construction machines such as wheel loaders and backhoe loaders, providing higher performance and lower fuel consumption by operating at high efficiency. It's about the system. KNOWN STATE OF THE TECHNOLOGY: Today, hydraulic systems can be used in heavy-duty machines, especially excavators, where high power density or fast load requirements are required. It is especially preferred for safe driving and efficient engine use. Providing high efficiency power control at engine speed in hydraulic systems is important for machine health. In hydraulic systems, ensuring power control at engine speed with high accuracy and efficiency is important for the productivity of the machine. In the current technique, power control in engines is provided by looking at the amount of deviation between the target and actual engine speed according to the angle of the vehicle's accelerator pedal. However, when the accelerator pedal is pressed, the engine does not react quickly and causes a deviation between the target speed requested from the engine and the actual speed. As a result, the control system obtained with this method may cause some errors and deviations. Even if the engine is capable of providing the torque needed by the system, the hydraulic system may reduce the power even if it is not needed. This causes low sensitivity, accuracy and loss of performance. As a result of a research conducted on the state of the art, the application numbered TR2019/11284 and titled high safety and low noise agricultural machine was found. The application in question relates to an agricultural machine comprising an engine for power transmission, at least one axle with two wheels, handlebars and a power output unit. The agricultural machine also includes a hydromechanical clutch group placed between the engine and the axle, and arms attached to the handlebars that control the said hydromechanical clutch group. The application in question describes an agricultural machine in general terms, but there is no mention of providing power control of the engine speed by gradually controlling the data transmitted from the engine. As a result, improvements are being made in automatic power and torque control systems, so new structures are needed that will eliminate the disadvantages mentioned above and provide solutions to existing systems. PURPOSE OF THE INVENTION The present invention is an automatic power and torque control system that meets the above-mentioned requirements, eliminates the disadvantages and brings some additional advantages. The main purpose of the invention is; It provides power control of the engine speed in construction and construction machines such as wheel loaders and backhoe loaders by gradually controlling the data transmitted from the engine. One purpose of the invention is; To provide higher performance, productivity and lower fuel consumption by operating at high efficiency. Another purpose of the invention; To provide automatic power and torque control system with high sensitivity and accuracy. The present invention aims to realize all the advantages mentioned above and which can be understood from the detailed explanation below; Speed sensors and CAN used in vehicles that detect the rotation speed, such as an operator cabin with an operator position where the operator is positioned, an engine room, a mechanism group that enables the movement of the work equipment, a scoop that enables the loading and unloading of the load, and a wheel loader that contains wheels that enable the vehicle to walk on the ground. An internal combustion engine containing a line, an accelerator pedal that controls the speed of the engine, angle sensors that detect the angle of the accelerator pedal, a variable displacement pump containing a swash plate that determines the flow rate to provide the flow rate needed by the hydraulic system, adjusting the displacement of the variable displacement pump by changing its angle. It is a power and torque control system to control the engine speed, including a power regulator that transmits a signal to the swash plate to provide the required torque, and a transmission that transfers the power received from the engine to the front axles and rear axles to provide the torque needed by the driving system consisting of wheels with different cycle rates. It receives and analyzes the data collected from speed sensors and angle sensors over the CAN line for comparison, determines the amount of deviation by comparing the target and real engine speed based on the data received from the speed sensors, compares the nominal torque value that the engine can deliver with the instantaneous torque value transmitted from the CAN line, and As a result of the comparison, if it detects that more torque value is requested from the engine than the engine can provide, it detects that the engine slides towards stalling and working in the inefficient region. If the engine is loaded with more torque than a predetermined rate, it enables power regulation by sending a signal to the variable displacement pump that feeds the hydraulic system. It contains a control unit that detects that the engine is overloaded and operates inefficiently by comparing the instantaneous amount of fuel consumed by the engine at a certain speed with the amount of fuel consumed by the engine at nominal loads and determining that the amount of instantaneous fuel consumed is more than the fuel consumed by the engine at nominal loads.

The invention, whose schematic view is given in Figure 1, is related to the power and torque control system that provides power control of the engine speed by gradually controlling the data transmitted from an internal combustion engine (6) in vehicles such as construction and construction machines. Here, the internal combustion engine (6) drives the variable displacement pump (1) and transmission (7) by providing the power needed by the vehicle. The variable displacement pump (1) contains an inclined plate (1a) that determines the flow rate to provide the flow rate needed by the hydraulic system variably. The inclined plate (1a) determines the flow rate through the signal it receives from a power regulator (2). The regulator (2) changes the angle of the inclined plate (1a) with the electrical / electronic signal sent by the machine control unit (3) and adjusts the displacement of the variable displacement pump (1). Here, the transmission (7) transfers the power it receives from the engine (6) to the front axles (10) and rear axles (11) in order to provide the torque needed by the walking system consisting of wheels (F) with different cycle rates. The front axles (10) and rear axles (11) transfer the torque they receive from the transmission (7) to the wheels (F) with a certain conversion rate and adjust the speed difference between the right and left wheels thanks to the differential system. In the power and torque control system of the invention. It contains speed sensors (6a) that detect the rotation speed of the internal combustion engine (6), and the speed of the internal combustion engine (6) is controlled manually or automatically by an accelerator pedal (4), hand or foot control. In order to detect the angle of the accelerator pedal (4), a wheel loader (A) is preferred as a work machine. The wheel loader (A) is most commonly used in loading and/or unloading operations of excavation through the work equipment located at the front. The types are: V/Y cycle, stack loading, leveling, load and carry. In the V/Y cycle, the machine loads the bucket excavation and unloads it to another area or vehicle. An operator cabin (B) is located where the operator who controls the vehicle is positioned. ), an engine room (C), a mechanism group (D) that enables the movement of work equipment, a bucket (E) that enables loading and unloading of the load / excavation, and wheels (F) that carry the entire body, which are in contact with the ground and enable the vehicle to walk on the ground. ) contains. Hydraulic cylinders (9) provide the movement of the bucket (E) and boom cylinders that constitute the work equipment. The bucket cylinder allows the bucket (E) to tilt and collect, and the boom cylinder allows the boom to move up and down. The main control valve (8) provides control of the work equipment by being controlled by electronic or hydraulic signals. In the power and torque control system of the invention, the engine (6) and all other components are managed by a machine control unit (3) to enable the system to control power with high accuracy. Communication between the control unit (3) and the engine (6) is provided by the CAN line (6b). The transfer of data received and sent from the engine (6) is transmitted over the CAN line (6b). Here, the control unit (3) performs comparison, analysis and detection tasks by receiving the data collected from the speed sensors (6a) and angle sensors (4a). The control unit (3) performs its duty in three stages: In the first stage, the target and actual engine speed are compared to determine the amount of deviation. If the difference as a result of the comparison is greater than the determined value, the second check is carried out. In the second stage, the torque value that the engine (6) can give is compared with the torque value drawn from the CAN line (6b). As a result of the comparison, it is determined that when more torque value is requested from the engine (6) than the engine (6) can provide, the engine (6) shifts towards stalling and operating in the inefficient region. Here, if the engine (6) is loaded with more torque than a predetermined rate, a signal is sent to the variable displacement pump (1) that feeds the hydraulic system, enabling power regulation. If the torque value remains below this rate, it continues to operate normally. In the third stage, the instantaneous amount of fuel consumed by the engine (6) at a certain speed is compared with the amount of fuel consumed by the engine (6) at nominal loads. The amount of fuel consumed by the engine (6) varies depending on the power drawn from the engine (6) and the speed at which the engine (6) operates. The fuel amount data consumed by the engine (6) at nominal loads is provided by the engine (6) manufacturer. If the instantaneous amount of fuel consumed is more than the fuel consumed by the engine (6) at nominal loads, it is determined that the engine (6) is overloaded and operates inefficiently.
