CATERPILLAR TRENCHER ACTUATOR CONTROL SYSTEM Russian patent published in 2016 - IPC E02F9/20 E02F5/14 

FIELD: transport.

SUBSTANCE: claimed set of inventions relates to the vehicle actuator control system and can be used for control over the digger or trencher. Claimed control system comprises the controller to generate the vehicle actuation signal for control over the vehicle motion. Note here that said controller exploits the hydrostatic drive fluid pressure as the variable for variation of the actuation signal. Besides, said control system comprises multiple signal variation inputs to be used for control over the actuation effect brought about by the vehicle actuation signal. Note here that said signal variation inputs comprises the components that follow. The first signal variation input is received from the actuation control to be controlled manually by the trencher operator. The second signal variation input is received from the actuation control to be controlled manually by the trencher operator. The third signal variation input is received from the hydrostatic actuator fluid pressure. The fourth signal variation input is received from the engine rpm. The fifth signal variation input received from the engine rpm or from the left hydrostatic actuator fluid pressure. The sixth signal variation input received from the engine rpm or from the left hydrostatic actuator fluid pressure.

EFFECT: minimal labour input, higher efficiency under all operating conditions.
