Abstract
A method for braking a wheeled vehicle which has at least one adjustable hydrostatic drive unit with a variable displacement pump and a motor and a driving engine wherein the vehicle driving engine absorbs a drag moment and the kinetic energy of the vehicle is partially reduced hydraulically after the maximum drag moment which is absorbable by the vehicle driving engine is exceeded. In the method positive hydraulic braking is achieved when a limiting rpm of the driving engine is exceeded and the vehicle is braked to a speed at which the incline output power is less than or of the same magnitude as the drag power which is absorbable by the driving engine.
