Nowadays, with the development of China’s economy and the improvement of science and technology, there are still some shortcomings and deficiencies in the research of hybrid electric vehicle engine energy-saving controller. The research results are often lack of stable effect, and the energy-saving effect is not significant enough. Therefore, the design of the engine energy-saving controller of hybrid electric vehicle to ensure its stability and good effect of energy-saving is an important research content nowadays. The purpose of this paper is to analyze the design of the engine energy-saving controller of hybrid electric vehicle, and to study the research field of the engine energy-saving controller of hybrid electric vehicle in depth, so as to create conditions for the improvement of the later level. Automobile is one of the most common and important means of transportation in the process of social development. In order to adapt to the development trend of today’s society, the automobile industry must pay attention to the problems caused by the shortage of resources.
Therefore, a hybrid electric vehicle with comprehensive utilization of electric energy, fuel, coal and diesel is formed. Hybrid electric vehicle engine energy-saving controller is an important part in the automotive field. Through the research and analysis of the design of hybrid electric vehicle engine energy-saving controller, the stability of its operation is ensured, and the good energy-saving effect is guaranteed.
Nowadays, the research on the engine energy-saving controller of hybrid electric vehicle mainly guarantees the dual development of its high stability and high energy-saving effect, and promotes hybrid electric vehicle to meet the new requirements in the field of transportation. The new energy-saving controller of HEV engine can control the driving system of HEV engine in all directions and has good energy-saving effect, but its price is too expensive to achieve effective promotion in a wide range, so it does not have good performance. In order to meet the energy-saving needs of the general public, it is necessary to create a hybrid electric vehicle engine energy-saving controller with high stability and energy-saving effect. At the same time, its design must meet the needs of the broad masses of the people. The design of energy-saving controller for hybrid electric vehicle engine mainly includes control chip and functional circuits. The control chip of HEV engine energy-saving controller is mainly single chip microcontroller, which is composed of internal components of HEV engine. It is common to select single chip microcontroller which has strong hardware compatibility and can correct the high efficiency energy-consuming signal of HEV engine in time to improve its performance.
Accuracy of output.
Taking the newly developed embedded X186 single chip microcontroller as an example, it meets the need of effective energy-saving control. It can detect and process the signals emitted by the engine of hybrid electric vehicle, so as to ensure the output of the engine signals. The X186 single chip microcontroller adopts the PID control method. The purpose is to convert the surplus mechanical energy of the hybrid electric vehicle engine into the high frequency electric energy used in the driving process of the vehicle. Due to the influence of engine speed, hybrid electric vehicle will have a greater impact on energy consumption. Therefore, it is necessary to construct a signal secondary processing circuit for the engine energy-saving controller of hybrid electric vehicle, and implement the secondary processing of speed signal. This kind of signal processing work needs the signal secondary processing circuit to have a higher signal transmission speed. Once a car is started, the sensors installed on the crankshaft of its engine will filter and rectify the speed signal of the engine. In order to effectively avoid the interference caused by the environment during the driving process of the car, attention should be paid to the diode and signal isolator in the process of signal secondary processing circuit. Install the forehead. The output control circuit is designed to collect and analyze the signals from the X186 MCU and the signal secondary processing circuit, so as to get the best plan. The output control circuit can connect all the processed signals in the energy-saving controller of the hybrid electric vehicle engine, and transmit the energy-saving plan of the engine quickly by format conversion and construction of transmission folder. The folder will be separated to a specific location according to the need in the transmission process, so as to ensure that the hybrid electric vehicle can achieve a specific energy-saving control effect in different locations.
The functions of the energy-saving controller of hybrid electric vehicle engine mainly include signal management, signal analysis, fault detection and background monitoring. The fault detection function often refers to the timely detection of the transmission signals of the hardware part, so as to detect the possible faults of the energy-saving controller of hybrid electric vehicle engine. Effective prediction and processing of the problem, which is often different from the impact of output control circuit on hybrid electric vehicle engine, should be strictly distinguished between the two. The function of signal analysis is to strictly manage the analysis and processing of the output control circuit. Background monitoring function can effectively monitor the energy-saving controller of HEV engine and HEV engine in real time to a certain extent. Once abnormal phenomena occur, it can be routinely predicted to avoid the deterioration of the problem, which involves long signal acquisition time and energy consumption overload. And the trend of circuit load is abnormal and so on. The PID control arithmetic in X186 single chip microcontroller is relatively simple, which mainly involves three control modes: proportional, integral and differential. The practical application of this PID control arithmetic in HEV engine energy-saving controller should be based on the inherent characteristics of these three control methods, so as to select the suitable P. ID control algorithm. To a certain extent, proportional PID algorithm can control the excess mechanical energy formed in the engine of hybrid electric vehicle timely and effectively, and the control effect is good, and the control efficiency is very high. Proportional PID control algorithm needs to control the excess mechanical energy is infinite growth, if the mechanical energy can be guaranteed to be stable in a constant value, then its control effect will also be affected, resulting in the gradual increase of control error, and constantly rapid growth, eventually leading to hybrid electric vehicle engine energy-saving control. The stability of the device is reduced. In addition, the integral PID algorithm control has the opposite form compared with the proportional PID algorithm control. The integral PID algorithm control needs the surplus mechanical energy existing in the engine of hybrid electric vehicle to show a steady state of increase or decrease. However, it should be noted that this control method has effective control performance, but it can not guarantee the good effect of energy saving for the engine. In addition, the control ability and control needs of differential PID algorithm control are mainly between integral PID algorithm control and proportional PID algorithm control. In summary, this paper takes the energy-saving controller of hybrid electric vehicle engine with high stability and high energy-saving effect as the research object. The X186 single chip microcontroller adopts the PID algorithm control mode to monitor and manage the hybrid electric vehicle engine in real time, thermostatic element and realizes the re-processing of speed signal through the signal secondary processing circuit. To some extent, the processing reduces the impact of engine speed on the energy consumption of hybrid electric vehicles.
At the stage of increasingly developed science and technology level, the development of automobile field must meet the pace of progress of the times. The design of energy-saving controller for hybrid electric vehicle engine must guarantee good energy-saving effect and have high stability. The optimization scheme of energy-saving controller for hybrid electric vehicle engine must be continuously optimized to ensure steam. The automotive industry can make progress towards energy saving and drive the progress of the automotive industry.
