Embodiment Construction
[0026] It is a general object of this invention to control the slope and spacing of the torque curve as a function of speed, system pressure and swash plate angle. This control includes (1) reducing the dependence of the swash plate angle on non-input signal parameters (ie: system pressure and speed); (2) increasing the dependence of the swash plate angle on the input signal; (3) ensuring that the overall operation of the vehicle The stability of speed, pressure and swash plate angle within the range; (4) reduce the vibration and noise of the swash plate in items (1)-(3).
[0027] The above objectives are achieved by combining various known control concepts, fine-tuning some or all of the concepts within certain parameters, which will be described in detail below. Through these concepts a control system is formed which can control the hydraulic transmission to have a control performance similar to that of the DFC system.
