Abstract
A hitch assembly control system is provided in which signals representative of battery voltage are used to generate a correction factor that is applied to control signals to a hitch actuator circuit to improve consistency in control. In an alternative embodiment, a correction factor is generated from signals representative of electrical parameters of solenoid coils included in the actuator circuit and this correction factor is applied to control signals to the actuator circuit. Also provided is a calibration method for a vehicle control system in which certain physical and electrical parameters of the vehicle and the control system are measured and stored during a calibration sequence for later use in the control of an implement coupled to an attachment member of the vehicle. A control method for a vehicle is also provided in which correction factors are generated from measurements of battery voltage or a solenoid coil parameter, and applied to control signals generated by a control circuit.
