A control and regulation device for a vehicle travel drive, which comprises two hydrostatic transmissions (3, 4) of adjustable transmission ratios, each comprising a hydraulic pump (12, 13) and a hydraulic motor (14, 15), which are in driving connection with two vehicle track arrangements (18, 19) and have each an adjustment device (30, 24; 31, 25) controllable with control signals (vl, vr) for adjusting the transmission ratio, with a control section comprising a desired-value setting apparatus (5) and a signal processing means (42, 43), whereby the desired-value setting means sets transmission ratio desired-values of each hydrostatic transmission, employing respective adjustable control levers (36, 37), and outputs desired-value signals (sl, sr), and the signal processing apparatus processes desired-value signals to control signals (sl, sr) and outputs the latter. For the avoidance of undesired travel speed alterations the signal processing (42, 43) is formed for the formation of a min./max. window from desired-value signals (sl, sr) for the determination of control signals (vl, vr) if the mean value of vl and vr lies within the min./max. window, and if not, corrects the control signals to be outputted.

A control and regulation device for a vehicle travel drive, which comprises two hydrostatic transmissions (3, 4), drivable in parallel by at least on drive motor (1), each transmission comprising at least a hydraulic pump (12, 13) and a hydraulic motor (14, 15) and having an adjustable transmission
A control and regulation device for a vehicle travel drive, which comprises two hydrostatic transmissions (3, 4), drivable in parallel by at least on drive motor (1), each transmission comprising at least a hydraulic pump (12, 13) and a hydraulic motor (14, 15) and having an adjustable transmission ratio, which are drivingly connected with a right or left wheel or track arrangement (18, 19) of the vehicle, and each transmission having at least one adjustment device (30, 24; 31, 25) controlled by control signals (vl, vr) for adjusting the transmission ratio, and a control section, which comprises a desired-value setting means (5) and a signal processing means (42, 43), wherein the desired-value setting means sets desired-values of the transmission ratio of each of the hydrostatic transmissions, employing respective adjustable control levers (36, 37), and for generating corresponding desired-value signals (sl, sr), and the signal processing means processes the desired-Value signals to form output control signals, characterised by, the signal processing means (42, 43) executes signal processing steps of: forming a min./max.-window from the desired-value signals (sl, sr) in accordance with the relations min.=minimum (sl, sr) max.=maximum (sl, sr) wherein in each case the lower value of the desired-value signal (sl or sr) represents the minimum value of the min./max.-window, and the higher value of the desired-value signal (sl or sr) represents the maximum value of the min./max.window, and determining control signals (v;, vr) to be outputted in accordance with the equations vlnm+(sl-sr) vr=nm+(sr-sl), if a mean value nm=(nl+nr)/2, corresponding to a speed of travel relative to the longitudinal axis of the vehicle, of the determined control signals (nl,nr) lies within the min./max. window, or correcting the determined control signals (nl+nr) of the preceding determining step, for deriving corrected control signals (vl,vr) to be outputted in accordance with the equations nml=nl+(min.-nm) vr=nr+(min.-nm) vm=min. and nm>max.: vl=nl-(nm-max.) vr=nr-(nm-max.) vm=max. if the mean value (nm) of the determined control signals (nr) lies outside the min./max. window.
