Traffic accident is one of the biggest cause of death around the world. Rear-end collision has the second largest amount of occurance after frontal collision in Indonesia. Collision avoidance system in the form of an automatic emergency braking system was developed to reduce the number of road traffic accidents. But the development of the collision avoidance system in Indonesia is minimal. The design process of the automatic emergency braking model is aimed to help the development of the collision avoidance system in Indonesia The design process of the model is started by designing the wheel model, and the automatic braking system model. Then, the design process of the control system will be conducted by using a conservative algorithm and proportional control. The test will be conducted by varying the proportional constant, the system delay time parameter, and the deceleration parameter on the algorithm. Based on the test results, the proportional constant of 35, the system delay of 0.3 seconds, and the deceleration parameter of 5 m/s, was chosen as the best combination of parameters. The test has a jerk result of -12.08 m/s3 ii and 11.44 m/s3 , with an average decceleration of 5.25 m/s2. So it can be concluded that the design process of the automatic emergency braking system model was successfully carried out and it produced a mechanical and control system model that was able to simulate the emergency braking process when the relative distance between vehicles was below the critical braking distance. However, a distance simulation system should be implemented for further developments, to have a better response result. In addition, the adaptive control system and the fusion network system of the sensors should also be implemented to obtain a better measurement with higher reliability.
