Average Braking Energy for a Vehicle Without Trailer on a Horizontal Plane and Downhill

The braking system is a main method for the safety of the Vehicle. The braking event is an aspect of vehicle stopping achievement where the kinetic energy due to speed of the vehicle converts to thermal energy via two or more friction surfaces. The average braking energy is the main point in our study. Some parameters of road structure impact on the vehicles braking performance. The article has analysis for the influence of road grade, tire rolling resistance coefficients, and tire slip during decelerate a vehicle without complete its wheel stop on the average braking energy at three different beginning speeds for the vehicle moving once on horizontal plane and other downhill by using two equations for the average braking energy.
