1. Vehicle characteristics : 4

2. Introduction of ABS The abs system was used mechanically in aircraft in 1930 and entered the automotive industry in light of the evolution of the automobile industry. The ABS brakes are used to prevent the car from slipping on the Liz roads, and this is done in several brakes instead of a braking action to prevent the car from slipping. The advantages of an automated system for the car include: 1 - The car stops sooner 2 - The car can also be driven during braking Disadvantages: The abs brakes in the frozen streets are extremely weak and do not go away. 5

7 As you can see, the speed of the car and the time of the car with the ABS system is slower, and the speed is reduced evenly. From the chart, which shows the amount of steering angle in time, it can be seen that a vehicle equipped with an ABS braking system does not brake in any direction and does not deviate from the road.

In the lateral acceleration chart, the time you see in the picture shows that a vehicle with an ABS has less variation and does not leave the car, but in the absence of the ABS, the trend is tangible and it is possible to leave the car there has it. In the yaw-timeline, a vehicle with a ABS brake system can be zero yaw and the vehicle without NO ABS has different values, indicating that it is moving in the car's brakes in a reversal. 8

9 In the pitch - time curve seen in this figure, in the ABS system, the value of the bolt starts from zero and reaches the value of 0. 7 and starts to change slightly, but the NO ABS braking system without behavior of the graph shows that the vehicle is in It is not equilibrium and totally deviated from its path.

5. Conclusion : The purpose of the project is to examine the behavior of two cars, one of which has an ABS braking system, and one of these vehicles without an ABS braking system. As you can see in this test, the vehicle with an ABS has a better performance on the wet surface, and it can be concluded that it is better to use the ABS braking system to make it easier for the vehicle to be stopped and faster. 12
