The paper deals with the problem of braking and braking systems with a focus on regenerative braking. Through the paper, with the help of available literature and other relevant sources, the topic itself is explained. As for braking and its system, it is one of the most dreamy factors of traffic safety. Braking is achieved when the driver acts on the command with his hand or foot. Activation of the brake system creates friction between the movable and immovable brake elements. As a result, the kinetic energy of the vehicle is converted into thermal energy which is released due to the working friction force of the fixed and moving elements of the excellent braking mechanism. The achieved braking torque depends on the engagement moment involved between the tire and the ground. The paper provides an overview of the importance of regenerative braking for today's traffic.
