Question 932 of 1208

What allows the electronic ABS control mode, in the situation of a beginning of blocking of one or more wheels, during the braking of the motor vehicle?

A a better loading of the wheels;
B the control of the direction of the motor vehicle;
C a controlled skid.

Explanation

When braking suddenly, the wheels can block, which significantly reduces the control over the direction of the motor vehicle. In this situation, avoidance maneuvers become almost impossible, increasing the risk of an accident.

To prevent the blocking of the wheels during braking, manufacturers developed the ABS system (Anti-lock Braking System). This system detects the moment when the brakes are applied with excessive force and automatically adjusts the pressure exerted on the brakes to prevent the blocking of the wheels. Thus, even in the case of emergency braking, the wheels continue to rotate, maintaining grip with the road surface. This allows the driver to keep control of the direction and to perform avoidance maneuvers, considerably improving traffic safety.

The correct answer is: B
