Control Method for Hydraulic Assistance
20200215909 · 2020-07-09 ·

A method for controlling a vehicle including a main transmission and a hydraulic transmission, in which, in the absence of a setpoint on the brake, and when the hydraulic transmission is activated, a hydraulic pump of the hydraulic transmission is controlled in such a way as to establish a predetermined pressure inside a hydraulic circuit of the hydraulic transmission, and in the event of a setpoint applied to the brake, the hydraulic transmission is then controlled according to an acceleration setpoint applied to the vehicle. If the acceleration setpoint is greater than or equal to an acceleration threshold value, and the speed of travel of the vehicle is less than or equal to a speed threshold value, the hydraulic transmission is controlled in such a way as to apply a tractive force. If the acceleration setpoint is less than the first threshold value, the hydraulic transmission is disengaged.

Operator Input For Alternative Traction Control

The present invention provides an alternative traction control system, in addition to a primary traction control system, in which a user selectable input can allow wheels of an agricultural machine to spin freely, such as for clearing debris from tires, until a predetermined deactivate condition occurs. Such a deactivate condition could comprise, for example, reaching a maximum rotation speed and/or temperature threshold with respect to a wheel. To minimize the risk of damage to propulsion components which may be caused by excessive rotation speeds and/or temperatures, upon reaching such a threshold, operation can return from the alternative traction control system to the primary traction control system. Such a system can therefore allow an on the fly change that would permit an operator to selectively spin the tires without damaging mechanical aspects of the sprayer.
