Abstract
A method a braking a vehicle which has a drive motor, a hydrostatic drive unit including adjustable hydraulic machines having adjusting devices, and an electronic subassembly controlling the adjusting devices of the hydraulic machines. Continuous adjustment of the hydraulic machines permits the drive motor to exert a braking moment that slows the movement of the vehicle. The method includes rapidly adjusting the hydraulic machines by the electronic subassembly toward a setting that relieves the drive motor completely or partially after a limiting rpm value on the drive motor is exceeded and the higher pressure present in the hydrostatic drive unit reduces the braking energy through the adjusting devices until the speed of the drive motor drops below the limiting rpm value. At this time, the electronic subassembly again adjusts the hydraulic machines to utilize the braking moment. The sequence is repeated until the braking moment imparted by the drive motor is sufficient to prevent exceeding the limiting rpm value of the drive motor.
