Minh City, March 2023 PP Group automotive market brings many negative aspects that need to be serious consideration of the Du Thành Vinh automotive industry The first problem is that internal combustion engines have contributed to increased environmental pollution In addition, rising fuel prices have pushed engine manufacturers to adopt new technology, optimize efficiency and reduce pollution One of the new technologies is the Adaptive Cruise Control (ACC) system widely used in modern vehicles, helping to improve the performance of the vehicle The ACC system helps maintain a stable vehicle speed in any environmental conditions, including wind or bad road conditions It also helps maintain a safe distance from the vehicle in front The results of simulation of ACC cruise control based on longitudinal dynamics for cars using Carsim software show that the PID controller meets the system requirements well The goal of the project is to have a deep understanding of the ACC system, using Simulink and Carsim to design control algorithms and simulate working modes and case studies for the 2021 Mazda CX-5 The project aims to optimize the vehicle's speed based on control parameters in different road types and estimate simulation models and results by modeling the system on the Carsim app In addition, the project aims to analyze the pros and cons of the ACC system in order to renew it later The project can contribute to saving energy and solving fuel consumption problems efficiently, helping users save fuel purchase costs The project can also prevent drivers from making mistakes on the road due to speeding A literature review included sources from Vietnam and other countries, demonstrating the benefits of the ACC system and how it works, and simulation results with PID controllers that meet the system requirements to maintain a constant vehicle speed The process of modeling an automotive tracking system involves simulating the host car and tracking the vehicle using CarSim, converting the simulation block to Simulink, and adjusting the values using the Simulink block Laplace and the differential equation are then concluded into the block to control speed through the throttle and brake systems, with the distance between the two vehicles calculated using a specific equation Finally, case studies are conducted to simulate road conditions in CarSim

the Cruise Control with PID 16 Fig 2.6 Graphs represent the data of Cruise Control with PID Contrary to the former case, the CCS with PID controller illustrates the signal smoother than the above

4: CONCLUSION 4.1 Conclusion In this paper, the controller design and the process in simulating Adaptive Cruise Control System on Carsim was described in detail, this consists of the reasons why to choose PID controller to illustrate ACC System (conduct distance and velocity control) Furthermore, the outcome has met almost the requirements that expected: - Research ACC system clearly and have a systematical knowledge to apply it into practical - Get more knowledge with Power train and the convert of the real condition into simulation as well as mathematics to find out the transfer function - Model the ACC system by Carsim: + The car can run constantly at the cruise control mode (follow the path) + The controller of ACC system works well (the car can adapt to the front vehicles) 4.2 Limitation Though the report got the requirements as supposed at the expected outcome, there still has some limitations: - Do not have enough time to design the ACC system on Simulink well - The conflicts and crashes between data in Carsim prevent from simulating different kinds of roads - Cannot estimate the level of saving fuel as well as money when the car activates Adaptive Cruise Control System Nevertheless, this is only a simulation with the absolute conditions Compared to the actual conditions, there so many factors below that affect to the ACC: 27 Road condition: Using cruise control on hilly or winding roads, where vehicle speed can change abruptly due to changes in terrain and road conditions, can be hazardous as the vehicle may travel too quickly or too slowly This means that the use of cruise control may not be appropriate in such conditions Similarly, in densely populated areas such as regions of Vietnam where roads are narrow, rough, and congested with traffic, the application of cruise control is limited to only highway or railway Cruise control systems are unable to react to unforeseen changes in traffic conditions such as the need to slow down or stop suddenly due to obstacles or hazards on the road In such situations, it is up to the driver to disable the cruise control manually and take control of the vehicle Weather condition: Cruise control systems rely on electronic components and sensors to operate effectively, which can increase their susceptibility to malfunctions and errors Therefore, Adaptive Cruise Control (ACC) may not work effectively in certain weather conditions, such as heavy rain, snow, or fog… In such situations, the radar system used in ACC may fail, resulting in erratic or unexpected vehicle behavior, which can pose a significant risk to safety 4.3 Development proposal Upgrade the Adaptive Cruise Control System to educated tool in University Add this technology into curriculum for students have a broaden knowledge about the development on Automotive Experiment in practice and evaluate the overall of the system about saving fuel, money and its efficiency 28 Bibliography [1] [2] Illya Verpraet - “The
