FIELD: transport.
SUBSTANCE: invention relates to automotive industry. Braking system comprises brake pedal, pneumatic braking modules, deceleration control circuit and pneumatic control circuit. Two stages of brake pedal correspond to operating condition and urgent braking condition. Pneumatic braking modules are intended for each axle and each module comprises proportional electromagnetic valve. Deceleration control unit receives data from pedal in compliance with pedal position and effects electric control over braking motor and/or proportional electromagnetic valve in operating or urgent braking conditions. Pneumatic control circuit operated solely in urgent braking condition to control proportional electromagnetic valve directly by the pedal pneumatic unit.
EFFECT: gradual and smooth braking, reduced braking time interval.
