Claims

[Scope of utility model registration request]

In a hydraulic transmission device installed as a propulsion power of a vehicle, a reference swash plate angle setting unit outputs a reference swash plate angle command signal for a hydraulic pump corresponding to the rotational speed of an engine; The present invention is characterized by comprising a correction swash plate angle setting unit that inputs a brake pedal depression signal and outputs a correction swash plate angle command signal that reduces and corrects the control swash plate angle of the hydraulic pump in response to the depression signal. Hydraulic transmission equipment for vehicles.
