Abstract
A working machine includes a machine body to attach a work attachment thereto, a pair of traveling devices to support opposite side portions of the machine body and to be driven independently of each other, a manual operator to be operated by a user in relation to travel of the machine body, and a controller configured or programmed to perform control relating to the travel of the machine body. The controller is configured or programmed to, while the manual operator is operated in relation to the travel of the machine body, drive the pair of traveling devices independently of each other based on at least one of a state of the machine body or a state of the pair of traveling devices to bring a travel state of the machine body into agreement with an instruction provided by operation of the manual operator.
Claims18
A working machine comprising:
- a machine body to attach a work attachment thereto;
- a pair of traveling devices to support opposite side portions of the machine body such that the machine body is allowed to travel, the pair of traveling devices being operable to be driven independently of each other;
- a manual operator to be operated by a user in relation to travel of the machine body;
- and
- a controller configured or programmed to perform control relating to the travel of the machine body;
- wherein
- the controller is configured or programmed to:
- while the manual operator is operated in relation to the travel of the machine body, drive the pair of traveling devices independently of each other;
- and
- if at least one traveling device of the pair of traveling devices skids such that a travel state of the machine body differs from a target travel state corresponding to an instruction provided by an operation of the manual operator, reduce a drive rotational speed of the at least one skidding traveling device to a value lower than a current drive rotational speed of the at least one skidding traveling device.
A working machine comprising:
- a machine body to attach a work attachment thereto;
- a pair of traveling devices to support opposite side portions of the machine body such that the machine body is allowed to travel, the pair of traveling devices being operable to be driven independently of each other;
- a manual operator to be operated by a user in relation to travel of the machine body;
- and
- a controller configured or programmed to perform control relating to the travel of the machine body;
- wherein
- the controller is configured or programmed to:
- while the manual operator is operated in relation to the travel of the machine body, drive the pair of traveling devices independently of each other;
- and
- if there is a speed difference between the pair of traveling devices that causes a travel state of the machine body to differ from a target travel state corresponding to an instruction provided by an operation of the manual operator, reduce a speed of one of the pair of traveling devices that is at a higher speed than the other.
