A working machine is provided, which includes a prime mover, a first traveling pump driven by power of the prime mover to supply operation fluid through a connector fluid tube, a traveling motor including first and second ports connected to the connector fluid tube, the traveling motor configured to be switched in a first speed and a second speed higher than the first speed, a first pressure detector to detect first traveling-pump pressure near the first port, a second pressure detector to detect second traveling-pump pressure near the second port, and a controller configured, with the traveling motor switched in the second speed, to automatically shift down the traveling motor from the second speed to the first speed, when a differential pressure between the first traveling-pump pressure and the second traveling-pump is equal to or more than a deceleration threshold.

A method for steering correction in a mobile machine having at least one ground-engaging device including one or more tracks or one or more wheels includes detecting a steering request with an electronic control unit, the steering request being generated by an input device configured to control steering of the mobile machine. The method also includes determining that the steering request is a request to propel the mobile machine in a straight path and determining, during travel of the machine, an amount of deviation of the mobile machine from the straight path. The method further includes generating an adjusted steering command based on the amount of deviation from the straight path.

A working machine includes a pair of traveling devices, a pair of traveling motors having a first speed and a second speed higher than the first speed, a pair of traveling pumps to supply operation fluid to the traveling motors, a connector fluid tube connecting the traveling motors and the traveling pumps, a traveling-pump pressure detector to detect a traveling-pump pressure that is pressure generated in the connector fluid tube, a revolving speed detector to detect a prime-mover revolving speed, a third storage to store a second decelerating judgment table representing a relation between the prime-mover revolving speed and a second decelerating judgment pressure, and a controller having: an automatic decelerator portion to perform an automatic deceleration process for reducing a speed of the traveling motor, and a differential pressure calculator portion to calculate a traveling differential pressure between one traveling pump pressure and another traveling pump pressure.

Disclosed embodiments include steering circuits utilizing a controllable cross-feed loop between left and right drive motor sides of an articulated power machine to reduce skidding caused by a turning operation in which an articulation actuator changes an articulation joint angle between a front frame member and a rear frame member of the power machine.

An autonomous traveling device to tow a cart including a caster, which swivels around an axis perpendicular to a rotation axis of a wheel, includes a drive wheel, and circuitry configured to detect a position of the autonomous traveling device, drive the drive wheel to move the autonomous traveling device, drive the drive wheel to move the autonomous traveling device backward, and drive the drive wheel to turn the autonomous traveling device. In response to a detection that the autonomous traveling device towing the cart is at a turning position, the circuitry drives the drive wheel so that the autonomous traveling device turn by a predetermined angle while moving forward or backward. Based on a determination that the autonomous traveling device towing the cart is at a moving-back position, the circuitry drives the drive wheel to move the autonomous traveling device backward to a target position.
