Abstract:
In a vehicle having a driven wheel, a hitch for attaching a ground-penetrating implement thereto, an actuator for raising and lowering the hitch to vary the ground penetration thereof in response to a hitch control signal applied to an input thereof, and a hitch control system for generating the hitch control signal as a function of sensed parameters and operator controls, the hitch control system comprising:a wheel slip generator for generating a sensed wheel slip signal indicative of a sensed amount of slippage of the driven wheel;an integrated wheel slip generator for generating an integrated slip signal using an integration function operating upon the sensed wheel slip signal;a proportional wheel slip generator for generating a proportional slip signal using a proportional function operating upon the sensed wheel slip signal;an operator operable slip response adjuster for generating a slip response adjuster signal; anda hitch control signal generator for generating the hitch control signal as a function of the integrated slip signal, the proportional slip signal and the slip response adjustment signal, the hitch control signal generator, in response to the slip response adjuster signal, varying a response of the hitch control signal to the integrated slip signal and the proportional slip signal.
