The invention discloses a road vehicle emergency braking system. The road vehicle emergency braking system is arranged at the lower end of a vehicle chassis. The road vehicle emergency braking system comprises a friction plate, a roller, an arc slide way, a winch, at least one lifting arm and at least one hydraulic arm. The arc slide way is composed of an inner arc rail and an outer arc rack which are sequentially arranged in the radial direction. The arc slide way and the winch are arranged at the lower end of the vehicle chassis. A winding rope on the winch is connected with the friction plate. The friction plate is collected or falls to the ground through collecting and releasing of the winding rope. The lower ends of the lifting arm and the hydraulic arm are hinged to the friction plate. The upper end of the lifting arm is hinged to the lower end of the vehicle chassis. The upper end of the hydraulic arm is arranged in the arc slide way and slides along the arc slide way when the hydraulic arm rotates around the hinge point of the hydraulic arm and the friction plate. Teeth are arranged at the upper end of the hydraulic arm. When the hydraulic arm stretches out, the teeth at the end of the hydraulic arm are inserted into teeth of the outer arc rack. The road vehicle emergency braking system is high in reliability, the emergency braking distance of a vehicle can be effectively reduced, and the braking effect on snow and rain slippery road surfaces is obvious.
