THE STABILITY OF THE VEHICLE DURING THE SERVICE BRAKING
The boundaries of the decelerations range, which restrict the vehicle to preserve stability during service braking are defined using the stability index. Analytical expressions to determine the boundaries of the specified range are obtained. The obtained results allow us to suggest the easiest way to ensure vehicle stability during service braking - delay on the rear brakes. The rational values of the braking force on the front axle are determined. Perfect condition for the support of all wheels on the blocking limit of the brake force distribution does not provide stability of the vehicle against skidding when the service braking is over the entire range of retardations from zero to j<sub>x</sub><sub>max</sub> = φ g.
