CONTROLLING A HYDRAULIC PRESSURE OF A FLUID TRANSMISSION

摘要

A control device for controlling a hydraulic pressure of a fluid transmission includes a pressure sensor for detecting actual pressure values of the hydraulic pressure, an electronic control unit for generating a control signal as a function of the actual pressure values detected by the pressure sensor and a reference pressure signal delivered to the control unit, a power switch controlled by the control signal and a solenoid valve actuated by the power switch for generating the hydraulic pressure. The control device is configured as a compact electromagnetic unit. The electronic control unit is respectively connected to the pressure sensor and to the power switch by a direct electrical connection. A method for controlling a hydraulic pressure of a fluid transmission is also provided.
