A method for determining a wheel reference speed of a wheel of a vehicle having a hydrostatic drive which uses a transfer medium, the hydrostatic drive acting at least on the one wheel, and the hydrostatic drive having an oscillating motor which may be swiveled to a pump mode via which a torque may be applied to the wheel, the method comprising:
- detecting with a wheel speed sensor a wheel speed, the sensor being situated near the wheel;
- and
- adjusting the oscillating motor to allow resistance-free flow of the transfer medium through the oscillating motor while the wheel speed sensor determines the wheel reference speed, wherein the wheel reference speed represents a speed of the wheel which is free running with the oscillating motor swiveled to a zero point at which the oscillating motor acts as neither a pump nor a motor.
