Title:
METHOD FOR CALCULATING VISCOSITY OF PRESSURE MEDIUM IN PRESSURE MEDIUM CIRCUIT
Document Type and Number:
Japanese Patent JP2019011045
Kind Code:
A
Abstract:
To provide a method for calculating viscosity of a pressure medium in a pressure medium circuit.SOLUTION: A brake circuit of an electronic slip-controllable vehicle brake device includes a pressure supply device that can be loaded via an operation mechanism, a sensor providing an operation signal indicating operation of the operation mechanism, a pressure sensor providing a pressure signal indicating a dominant pressure in the pressure supplier, and an electronic control unit, and further processes the signal in the electronic control unit. The electronic control unit records the operation signal and the pressure signal so as to be time-synchronized with each other, calculates a quotient from the value, and determines viscosity corresponding to a pressure medium by the recorded characteristic curve. An electronic controllable actuator is controlled depending on the calculated value.SELECTED DRAWING: Figure 2
