Abstract
A method and device for controlled braking of a vehicle using a hydrostatic drive is provided. Two pivotal hydraulic motors are connected to a respective axle of the drive, driven by a hydraulic pump and regulated by a respective regulating circuit. For each axle of the drive, a respective reference variable containing the difference between a set value and the actual value of a speed of the driven wheel is continuously determined and fed back to the respective regulating circuit. A displacement of the axle load of the vehicle from a current deceleration (a) of the vehicle is dynamically determined. A resultant braking force acting on the axle driven by the hydraulic motor is determined and put into effect by the hydraulic motor through adjusting a corresponding pivot angle. A deceleration-dependent distribution of the braking force is then provided to the respective axle by a control program.
