Abstract:
A system and method to level a vehicle. The method utilizes a reference current draw unique for each individual actuator that is measured and saved at measured temperature and actuator actuating duration times. The reference current draws are adjusted by a fixed predetermined compensation increment and by a variable predetermined time and temperature increment. During operating function steps, actual extend and retract current draws are measured, which may be at another temperature and duration time. The adjusted reference current draws are compared to the actual extend and retract current draws to determine when desired conditions such as ground contact or fully retracted condition are achieved.
