摘要: A method for calibrating hydraulic actuators includes installing an actuator in a test stand and performing an electrical signal sweep to obtain a series of pressure values. Based on desired pressure values, signals yielding unwanted pressure values are removed and the remaining signal values and pressure values are stored in a central database as a look-up table for the actuator. Multiple actuators are then assembled to form a module assembly. The customized look-up tables for the actuators forming the module assembly are retrieved from the database. Based on those tables, signals are applied to the actuators to determine if the pressure values fall within specified tolerance windows. If the pressure values fall within the specified tolerance windows, the customized look-up tables are stored in the memory of a vehicle electronics package. If not, the signals are adjusted so that the pressure values fall within the specified windows, and the adjusted customized look-up tables are then stored in the memory.
