Abstract
The present disclosure is directed to an agricultural work vehicle and a method of controlling the same. According to the present disclosure, a set vehicle speed may be varied while maintaining a constant-speed driving mode, and the control of the hydrostatic transmission is performed to maintain the set vehicle speed, thereby improving the convenience of use and utilization rate of an agricultural work vehicle.
Claims11
An agricultural work vehicle, comprising:
- a hydrostatic transmission configured to vary a speed depending on a rotational angle of a swash plate;
- a controller configured to control the rotational angle of the swash plate by generating a control current intended to adjust the rotational angle of the swash plate and providing the control current to the hydrostatic transmission, and provided with a constant-speed driving control function of enabling driving while maintaining a set vehicle speed set for constant-speed driving in a constant-speed driving mode;
- sensors configured to provide the controller with information required to control the rotational angle of the control plate;
- a constant-speed driving switch configured to input a command to activate the constant-speed driving control function to the controller;
- and
- a speed setting switch configured to input a command to variably adjust the set vehicle speed required for constant-speed driving while maintaining the constant-speed driving mode during a process in which the controller controls the hydraulic transmission in the constant-speed driving mode through activation of the constant-speed driving control function;
- wherein when a command to vary the set vehicle speed required for constant-speed driving is input via the speed setting switch, the controller controls the hydraulic transmission to vary the set vehicle speed while maintaining the constant-speed driving mode.
4 more elements
A method of controlling an agricultural work vehicle, the method comprising:
- an information collection step of collecting information used to determine a load state when a constant-speed driving mode is activated;
- a load determination step of identifying a current load state by analyzing the information collected in the information collection step and determining the current load state;
- and
- an angle control step of controlling a rotational angle of a swash plate in a hydrostatic transmission according to the current load state determined in the load determination step.
