A Smart Car Control Model for Brake Comfort Based on Car Following

This paper demonstrates a novel car-following model focused on passenger comfort, for example, a rapid deceleration will make passengers uncomfortable. The brake comfort model of car following was set up according to the relationship between vehicle deceleration and passenger comfort levels. The model calculates the controlled car´s acceleration by measuring the distance between the controlled car and its preceding car, as well as the velocity of the controlled car. By controlling the car´s acceleration, the model is able to keep riders feeling comfortable. The friction coefficient between the car and the road surface is also considered. Experiments show that the model is highly compatible with real cases.
