Braking characteristics are a very important element in vehicle performance. In this regard, the most common technology used to date is to obtain the maximum friction between the tyre and the road surface through the ABS control. However, most of the ABS developments have been carried out on vehicles. These developments have temporal / spatial limitations. Using simulation techniques as an alternative to resolving problems, this paper is used to execute the ABS through the simulation technique and demonstrate that the results have been correlated.

This research proposes a navigation algorithm using RTK-GPS units and encoders. GPS systems sometimes lose their signals and receive inaccurate position data due to many factors, such as obstructions. This paper shows that GPS failure can be solved by using a DR (dead reckoning) navigation method with encoders and that position errors can be decreased by using RTK-GPS units. In addition to this method, new way point update algorithm and steering algorithm using RTK-GPS units will be introduced.
