An autonomous travel work system works, regarding a garden LD as a canvas and applying an arbitrary design to the garden LD, according the design. The autonomous travel work system includes an information terminal configured to be input means and transmit input information, a computer configured to receive the input information, and at least one electric lawn mower configured to work autonomously traveling in the garden LD. The information terminal includes a display, a work ground input, a design allocation input, and a work request device. The information terminal or the computer includes a work ground designation device, a design allocation device, a mapping route generator, and a work pattern generator.

Autonomous travel work system

A vehicle capable of easily translating in an arbitrary direction. A vehicle comprising: wheels composed of two front wheels and two rear wheels; four steering actuators connected to the wheels, respectively, and steering the wheels; four drive actuators connected to the wheels, respectively, and driving the wheels; a joystick () tiltable in an arbitrary direction to perform operation and instructing the operation of the steering actuators; an accelerator pedal () for instructing the operation of the drive actuators; and a controller () which, when the joystick () is tilted, steers the wheels in the direction in which the joystick () is tilted, and when the accelerator pedal () is operated, drives the wheels on the basis of the amount of the operation of the accelerator pedal ().

Vehicle and feedback control method

The purpose of the present invention is to provide a work vehicle that does not slip. The work vehicle has an engine () generating a rotational power, a hydraulic stepless transmission (HST) () having a hydraulic pump () and a hydraulic motor () and changing the speed of rotation generated by the engine () and transmitting it to drive wheels (), an actuator () for adjusting the transmission ratio of the HST () by changing the tilt angle of a movable swash plate () of the hydraulic pump (), a shift lever (speed setting means) () for setting the speed of a motor output shaft () changed by the HST (), and a control device () for controlling operation of the actuator () so that the speed of the motor output shaft () changed by the HST () changes at a predetermined rate of change (&#x3b2;) until it reaches the speed (preset speed) set by the shift lever ().

Work vehicle
