Importance of the brake pedal simulator applications. 
Today’s advances in computer technologies and a higher implementation of simulation tools in 
engineering, the use of driving simulators has a particular role in the study of the automotive components.
Speaking about the advantages of brake pedal simulators, we should mention several advantages 
that make them useful: 

Controllability, reproducibility and standardization. 
The simulators based on electric drives 
prove themselves reliable from control point of view. Moreover, such systems possess good 
reproducibility.
 

Ease of data collection.
An obvious advantage can be that the performance in the simulator can 
be measured quite accurately. On the other hand, it can be complicated to make proper measurements in 
rear vehicles.
 

Possibility of integrating the brake simulator to the overall driving simulator.
Brake pedal 
simulator can be used as an important part in the driving simulator. It provides a very good understanding 
of vehicle behavior during driving and deceleration because the simulator is equipped with haptic 
feedback which emulates the feedback of a real brake pedal;
 

Implementation in Brake-By-Wire systems.
Brake-By-Wire system is a relatively new tendency 
in braking systems. The concept of the technology claims that some of the conventional hydraulic 
components of the braking systems are replaced with electronic control systems. This technology is 
widely used in Hybrid Electric Vehicles and Battery Electric Vehicles which exploit the idea of 
regenerative braking.
 

Testing.
Being a part of driving simulator, the brake pedal feedback simulator can be used to 
test the braking system for safety and comfort. The current advanced car simulator allows to obtain quite 
a realistic feedback from driving. Besides, the vehicle dynamics performance can be analyzed[4].
 
However, in spite of the listed advantages, there exist some disadvantages that impose certain 
limitations in the use: 

Limited physical, perceptual and behavioral fidelity
. Despite the feedback that can be provided 
by the simulators, there are still a lot of challenges to improve the haptic perception received by the driver 
from the simulators. 

Shortage of research demonstrating validity of simulation
. Before making sure the simulator 
provides an adequate feedback, it has to be compared to the real data obtained from vehicle dynamics 
experiments in order to check for validity. Sometimes it can be quite time-consuming and costly to 
conduct a proper real vehicle dynamics experiment[1].
